Description:
Plug Insert for a Connector Assembly and Connector Assembly

The invention relates to a plug insert which is configured to be inserted into a connector assembly. The invention further relates to a connector assembly. Plug inserts which are for instance applied as cable termination units and connector assemblies are known from the art. For data transmission applications, data lines are in general terminated and electrically contacted by means of insulation displacement contacts (IDC), wherein the plug insert or cable termination unit may provide interface means between the data lines and contacts of the connector assembly. Prior art solutions may not provide a reliable contact between the IDC and a cable or wire. Prior art solutions may also suffer from insufficient position accuracy.

An aspect of the present invention is therefore to provide a plug insert and a connector assembly which combine a reliable contact between the IDC and a cable or wire as well as a high position accuracy of the IDC. This object is achieved by the present invention for the plug insert mentioned in the beginning in that the plug insert comprises a plug insert body, comprising at least one contact member accessible from outside the plug insert and at least one IDC, which is electrically connected to the contact member wherein the plug insert further comprises at least one wire manager module, comprising at least one cable receptacle for receiving and holding a cable or wire, wherein the plug insert body comprises a guiding assembly, the guiding assembly being configured to guide the wire manager module relative to the plug insert body from a pre-assembly position to an assembly position, in which the IDC extends into the cable receptacle.

The object is further achieved by the present invention for the connector assembly mentioned in the beginning in that the connector assembly comprises a connector housing and a plug insert according to the invention with at least one cable receptacle extending along a cable insertion direction, wherein the wire manager module is configured to be moved from the pre-assembly state to the assembly state in a direction perpendicular to the cable insertion direction, and wherein the connector housing is configured to receive the plug insert along the cable insertion direction.

The invention thus has the advantage that, by the guiding assembly, the at least one IDC may be reliably and accurately inserted into the cable receptacle, in which the IDC may reliably contact a wire or cable. As mentioned above, the plug insert may be referred to as cable termination unit as well. The pre assembly or assembly position may also be denoted as pre-assembling position and assembling position and may denote a pre-assembly state and an assembly state, respectively. Preferably, the IDC does not extend into the cable receptacle in the pre-assembly position, whereas it extends into the cable receptacle in the assembly position.

The inventive plug insert and the inventive connector assembly may be improved by further technical features. Those features will be described in the following for specific embodiments of the invention, wherein the technical features of different embodiments may be arbitrarily combined with each other or may even be omitted in the case that the objective technical effect obtained by the omitted technical feature is not essential to the present invention.

In one embodiment of the inventive plug insert, the wire manager may be latched to the plug insert body in the pre-assembly position. The pre-assembly position may represent a delivery state of the plug insert. By latching the plug insert body to the wire manager, both elements are attached to each other and neither may be lost. The entire plug insert is thus ready for application without the need to assemble the wire manager module to the plug insert body.

Particularly, the latching means position the wire manager module at a clearly distant position from the plug insert body for an effective guiding of both elements towards each other.

For latching, the plug insert body and/or the at least one wire manager module may comprise at least one latch mechanism or catch mechanism which is configured for providing a releasable engagement between the plug insert body and the at least one wire manager module. Consequently, two, three, four, or even more catch mechanisms may be provided, wherein they may be provided on the plug insert body or on the at least one wire manager, or on both.

The latching of the wire manager to the plug insert body may be releasable, wherein in the latched position, a necessary force to move the plug insert body towards the at least one wire manager module may exceed the force which may be introduced or exerted by a person installing the plug insert (the user) by hand. The force to move the plug insert from the pre-assembly position to the assembly position may require the application of a tool, like pliers. Further, a removal force necessary to completely separate the plug insert body from the at least one wire manager module may be greater than the force required to arrive at the assembly position.

In a further embodiment, the guiding assembly may comprise at least one guiding post on the wire manager module or on the plug insert body. The guiding post may provide the latching, wherein a further guiding post may be provided as well as another further guiding post. Consequently, two, three, four, or even more guiding posts may be provided at the wire manager module for the plug insert body, or at both elements. Preferably, in order to clearly determine a guided movement, three guiding posts are provided. The guiding posts may be provided in the corners of the plug insert body. The at least one guiding post, or, alternatively, the two, three, four, or more guiding posts, may protrude from the at least one wire manager module and/or extend from the plug insert body towards the respective plug insert body or the respective wire manager module. A plurality of guiding posts may be provided. Similar or even identical guiding posts may be provided on the plug insert body and/or at the wire manager module.

When terminating a cable or wire it is thus easy for the user to move the at least one wire manager module from the pre-assembly position of the plug insert towards the plug insert body to arrive at the assembly position. The guiding posts thus may unambiguously define the direction in which, respectively, a distance over which the at least one wire manager module may be moved towards the plug insert body.

The at least one guiding post may be slidingly engaged in a guiding recess. The guiding recess may therefore interact with a respective guiding post. Accordingly, a further guiding recess may interact with a respective further guiding post. A plurality of such interacting pairs of guiding posts and guiding recesses may be provided, wherein the guiding post may be provided either on the plug insert body (or on the at least one wire manager module). Accordingly, the guiding recess is embodied at the corresponding, i.e. interacting, wire manager module (or at the plug insert body).

In a further embodiment of the inventive plug insert, the at least one wire manager comprises at least one stopping member, which, at least in the pre-assembly state, blocks a movement of said wire manager towards the plug insert body.

The stopping member or stopper rib may be understood as a limit stop for the at least one wire manager module. A further movement of the wire manager module towards the plug insert body is thus prevented by the stopping member. This limitation may be achieved by abutment of the stopping member with a corresponding counter limit stop of the plug insert body. The stopping member may be provided in the guiding recess or at the guiding post. The stopping member and/or the counter stopping member may in particular be located in a corner of the guiding recess or at a corner of the guiding post.

Any number of guiding posts may be provided without a stopping member, wherein further guiding posts may be provided with at least one stopping member. In particular, the plug insert body may comprise four guiding posts extending towards the wire manager module in corners of the plug insert body. The plug insert body may comprise a cable termination portion in which the cables or wires will be contacted by the IDC, and a stabilization portion, in which no contacting occurs.

The guiding posts may in particular be located in the corners of the cable termination portion. Additionally, guiding posts being different from the guiding posts in the corners may be provided at the plug insert body and may additionally provide the latching means for latching the wire manager module to the plug insert body.

The at least one stopping member may be broken in the assembly state. In other words, during assembly, i.e. in the case that the plug insert is brought from the pre-assembly position into the assembly position, the counter-stopping member is pressed against the stopping member and damages, i.e. breaks, the stopping member. A broken stopping member may be applied as an indicator, showing that the present plug insert is no longer pristine. Thus, even if the at least one wire manager module is unlatched from the plug insert body, it is unambiguously clear to a technician that said plug insert at hand has already been applied before.

This increases security of applications in which the inventive plug inserts are used as already applied and possibly damaged or malfunctioning plug inserts may be easily recognized.

The at least one stopping member may comprise a predetermined breaking point at which the at least one stopping member is broken off when changing the state of the plug insert. The breaking point is to be understood as a region where breaking of the stopping member is desired and planned. The breaking point is thus not to be understood as a single point, but rather as a line along which breaking occurs. At this breaking point, the structure of the stopping member may be weakened by a mechanical, thermal or chemical treatment.

In a further embodiment, the plug insert body may comprise two adaptor plates and a circuit board, the circuit board being arranged between the two adaptor plates. The plug insert body may thus be a single piece or may be constructed from two or more elements.

A plug insert body comprising of two or more elements may increase the versatility of the inventive plug insert and connector assembly. One may apply PCBs with the same size and shape but with a different circuit layout. Thus, different connection geometries may be realized with one plug insert geometry, simply by using different PCBs. The guiding assembly may be provided at least partly on the adaptor plates. In a further embodiment, the two adaptor plates may be identical to each other. In the pre-assembly position, there may be provided a first adaptor plate and a second adaptor plate in between which the circuit board is provided. Only the orientation of the adaptor plates may be different between the first and the second adaptor plate. They may be mirrored with respect to the PCB or simply rotated identical plates. Each of the adaptor plates may be provided with at least one guiding post and/or at least one guiding recess.

In an advantageous embodiment of the inventive plug insert, the two adaptor plates are heat stacked to each other. Heat stacking represents a beneficial way for attachment avoiding thermal influence to further components, namely the circuit board provided between the two adaptor plates. At least one of the two adaptor plates may provide a heat stacking element which may be provided in the form of a longitudinal post extending from one adaptor plate through a corresponding hole in the circuit board and through the further adaptor plate. During heat stacking, the portion extending from the further adaptor plate is heated under application of a pressing force and thus forms a deformed end which may not be removed from the further adaptor plate or the circuit board. This deformed portion may be similar to a rivet head. By fixing the position of the at least one wire manager module with respect to the plug insert body, the tolerance claims may be optimized.

Further means for fixation of the wire manager module(s) to the plug insert body are gluing, clamping or mortising.

Heat stacking is preferably performed applying a polymer which may be easily heated and melted.

In a further advantageous embodiment of the inventive plug insert, the plug insert comprises two wire manager modules, wherein the plug insert body is arranged in between the two wire manager modules. Such a structure may in particular be symmetric, i.e. that identical adaptor plates sandwich the circuit board, wherein such a structure is sandwiched by the two wire manager modules. In particular, only a main part or main portion of the plug insert body - the cable termination portion - may be arranged between the two wire manager modules. In such an embodiment, further elements of the plug insert body may extend from the sandwich structure, i.e. may not be arranged between the wire manager modules but represent a stabilization portion. A structure of the PCB extending out of the sandwiched portion may represent further connection means, i.e. in the form of contact pads or contact regions provided on the circuit board. Further, portions of the adaptor plates also may not be located between the two wire manager modules for providing stability to the corresponding portion of the circuit board.

Further, the at least one IDC may be held and positioned by one adaptor plate. Preferably, each adaptor plate carries, positions and holds the same number of IDC members. The IDC members may only be oriented in opposite directions for the different adaptor plates. The orientation of the IDC is to be understood as the direction into which the blades cutting the insulation of a wire or cable open.

The at least one IDC may comprise an insulation cutter member configured to cut through the insulation of a cable or wire and a cable cutter member configured to cut a cable or wire. Thus, by receiving at least one cable or wire in the at least one cable receptacle of the wire manager module and by moving the wire manager module towards the plug insert body, the pre-assembly position of the plug insert is changed into the assembly position, thereby the cables or wires are electrically contacted and cut to a required length in one assembly step.

If the IDC is secured to the plug insert body this positioning of the IDC secures that only at certain positions a contact is made with the PCB. IDCs are commonly used for data connection/fixation to the plug insert body by clamping, by pressing/force fitting, gluing, or by mortising.

The IDCs may be positioned directly on the PCB which optimizes the chain of tolerances and improves accuracy. Heat stacking may be applied as an alternative to gluing, in which the PCB is clamped at the number of heat stacking points, whereas gluing is applied over the larger area, heat stacking is a punctual connection.

It is preferred if the at least one cable receptacle extends along a cable insertion direction, and that the wire manager module is configured to be moved from the pre-assembly position to the assembly position in a direction which is oriented perpendicular to the cable insertion direction.

In particular, the cable receptacle may be tube-like, wherein the tube-like cable receptacle may consist of several tube-like sections. Said tube-like sections may preferably be aligned with each other, such that it is not necessary to bend the wire or cable to receive it in the cable receptacle. The cable receptacles are thus configured to receive a straight cable or wire without the necessity of bending the cable or wire.

In the following, the present invention will be described based on figures that show specific embodiments. The embodiments shown in the following therefore do not limit a possible scope of protection which is defined by the claims. They merely show specific combinations of technical features. The technical features indicated in the figures may be arbitrarily combined with each other or may even be omitted if the technical effect obtained by the omitted technical feature is not essential to the present invention. The description of features present in one figure may be applied to the same feature in other figures. A repetition of the description of such features is avoided. The figures show:

Fig. 9 an inventive connector assembly.

Fig 1 shows a first embodiment of the inventive plug insert 1 in an exploded view. The plug insert 1 comprises a plug insert body 3 which in the embodiment shown comprises two contact members 5 that are accessible from outside the plug insert 1. The plug insert body 3 further comprises two IDCs (insulation displacement contacts) 7, which are electrically connected to the two contact members 5.

The plug insert 1 further comprises a wire manager module 9 with two cable receptacles 11 for receiving and holding a cable or wire (not shown).

It is to be noted that in different embodiments, a different number of IDCs 7 and contact members 5 may be comprised. The abbreviation 'IDC' denotes a single insulation displacement contact or a plurality of two, three, four or more of such. Also the shape (rectangular) of the plug insert body 3 and the wire manager module 9 are purely exemplary for the embodiment shown, and different shapes are possible.

In Fig. 2 a further embodiment of the plug insert body 3 is shown. This embodiment is applied in the subsequent figures 3 to 9. Also the embodiment of the plug insert body 3 shown in Fig. 1 may be combined with the subsequently described additional technical features. The plug insert body 3 shown in Fig. 2 comprises two adaptor plates 13 in between which a circuit board 15 is arranged. The plug insert body 3 comprises a cable termination portion 17, a stabilizing portion 19 and a contacting portion 21.

In the cable termination portion 17 the IDC 7 are arranged. The stabilizing portion 19 represents a portion in which the PCB 15 is stabilized by two protrusions 23 of the two adaptor plates 13. In the contacting portion 21 the contact members 5 are provided to the outside of the plug insert 1. In this embodiment, four IDC are provided, whereas the two of them are held and positioned by the lower adaptor plates 13a. Accordingly, the upper adaptor plate is arranged on the opposite side of the PCB (the circuit board 15 may be referred to as PCB 15). The labeling "upper" and "lower" is arbitrary and may be replaced by a first 13a and a second adaptor plate 13b.

The plug insert body 3 comprises a guiding assembly 25 which comprises six guiding posts 27. In the first embodiment of Fig. 1, the plug insert body 3 exactly comprises six guiding posts, wherein the second embodiment of Fig. 2 comprises six guiding posts 27 per adaptor plate 13, i.e. twelve guiding posts 27.

Two of the guiding posts 27 further comprise latching means 29. The latching means 29 have a latching beak 31 which may interact with a counter latching means 33 provided at the wire manager module 9 (see Fig. 1).

In the embodiments shown, the six guiding posts 27 (per adaptor plate 13) extend away from the plug insert body 3, respectively from the corresponding adaptor plate 13 (in the second embodiment) towards the wire manager module 9.

Accordingly, in the second embodiment shown in figures 2 to 9, six guiding posts 27 extend away from the circuit board 15 to each side. In other words, six guiding posts 27 extend upwards from the upper adaptor plate 13b and another six guiding posts 27 extend downwards from the lower adaptor plate 13a. The labeling upper and lower is arbitrary in view of the orientation shown in the figures and does not limit the invention to exactly this orientation. The upward direction 35 and the downward direction 37 is indicated in Fig. 2.

Four of the six guiding posts per side are arranged or located in the corners 39 of the cable termination portion 17.

In Fig. 2, heat stacking members 41 are shown in a processed state 43. An unprocessed state 45 of the heat stacking members 41 is shown in a circle 47. Such an unprocessed heat stacking member 41 extends through a hole 49 in the corresponding adaptor plate 13 and is heated and melted by a tool (not shown), thereby forming a head 51 of the heat stacking member 41 in the processed state 43. This head 51 attaches the two adaptor plates 13 to the circuit board 15. The heat stacking member 41 may be provided as a separate piece or may be formed monolithically with one of the lower adaptor plate 13a and/or the upper adaptor plate 13b. The circuit board 15 provides corresponding holes (not shown) to allow passing through of the heat stacking member 41.

In all embodiments shown, the IDC 7 comprises two opposing IDC blades 53 which may also be referred to as insulation cutter members 53. The IDCs 7 further comprise a cable cutter member 55. The insulation cutter members 53 are configured to cut through the insulation of a cable or wire and to electrically contact the core of said cable or wire. The cable cutter member 55 is configured to cut excess cable or wire. This will be briefly explained with reference to Fig. 7 below.

In Fig. 3 and Fig. 4, a second embodiment of the inventive plug insert 1 is shown in two different perspective views. The plug insert 1 comprises the plug insert body 3 of Fig. 2, which is comprised of the circuit board 15, the two opposing adaptor plates 13 and two wire manager modules 9 in between which said plug insert body 3 is located.

In the embodiment shown, the two wire manager modules 9 each provide two cable receptacles 11, each for receiving one cable or wire (not shown). An according number of contact members 5 is provided in the contacting portion 21 of the plug insert 1.

As can be seen from the figures, the cable receptacles 11 (best seen in Fig. 4) represent a tube-like structure 57, which is embodied straight, i.e. without any curvature or bent sections. In different embodiments, such curvatures or bent sections may be present. Thus, a straight cable or wire may be received without the need of bending said cable or wire.

The cable receptacles 11 define a cable insertion direction 59.

The wire manager modules 9 are movable along an assembly direction 61 which is oriented perpendicular to the cable insertion direction. Each wire manager module 9 has its own assembly direction 61, which is identical to the upward direction 35 for a lower wire manager module 9a and which is identical to the downward direction 37 for an upper wire manager module 9b (the upward 35 and downward direction 37 are shown in Fig. 2). Accordingly, a first assembly direction 61a and a second assembly direction 61b may be defined, which are directed opposite and parallel to each other.

The guiding posts 27 are each received in a corresponding guiding recess 63, which is (in the embodiment shown) provided in the wire manager modules 9. In Fig. 3 the nine visible guiding recesses 63 are indicated. In different embodiments, the guiding recess 63 may be provided in the adaptor plate 13 and a corresponding guiding post 27 may be provided in the wire manager module 9. Each of the adaptor plates 13 or the wire manager modules 9 may comprise both guiding recesses 63 and/or guiding posts 27. The same applies to the first embodiment shown in Fig. 1 with only one wire manager module 9.

The guiding posts 27 are slidingly guided by the corresponding guiding recess 63. As mentioned above, all six guiding posts per side of the plug insert 1 are guiding the wire manager module 9 from the pre assembled a pre-assembly position 65 to an assembly position 67 (see Figs. 8 and 9).

Further details of the guiding assembly 25 are shown with reference to Fig. 5 and Fig. 6. In Fig. 5, it can be seen that the guiding recess 63 of the wire manger module 9 (those details are describe with reference to only one wire manager module 9 and may be transferred to the corresponding further wire manager module 9) comprises a stopping member 69, which is in abutment with a counter stopping member 71 of the corresponding adaptor plate 13. Said stopping member 69 (which may also be called stopper rib) prevents a manual transfer from the pre-assembly state or pre-assembly position 65 into the assembly position 67 by hand. When the assembly position 67 is reached, the stopping member 69 is broken and may be applied as an indicator for an already installed plug insert 1. The stopping member 69 is located in a guiding corner 63a of the guiding recess 63. The stopping member 69 represents a limit stop 70.

The stopping element 69 comprises a predetermined breaking point 69a. At this predetermined breaking point 69a the material of the stopping element 69 may be weakened by mechanical, thermal or chemical processing. Flere, the stopping element 69 will break when the cable manager module 9 is moved further towards the plug insert body 3. A further detail is shown in the cut view of Fig. 6. Flere, two of the six guiding posts 27, namely latching posts 73, per adaptor plate 13 are in engagement with a corresponding counter latching member 33 of the wire manager module 9.

The counter latching means 33 of the wire manager modules 9 comprise a recess 75 into which the latching beak 31 is inserted in the pre-assembly position 65. The latching beak 31 abuts a planar surface 77 of the recess 75, preventing the wire manager module 9 from being removed from the corresponding adaptor plate 13. The planar surfaces 77 are oriented perpendicularly to the assembly direction 61.

The counter latching means 33 further comprise a shoulder 79. In the assembly position 67 the latching beak 31 engages with said shoulder 79 and prevents the disengaging of the corresponding wire manager module 9 from the plug insert body 3 and thus maintains the plug insert in the assembly position 67. The process of contacting a cable or wire 81 is shown with reference to Fig. 7 and Fig. 8. The data cable 83 is shown. The insulation is removed and four single cables or wires 81 (see Fig. 8) are inserted into the four cable receptacles 11. Even if they are indicated on the left side of the Figure, the cables or wires 81 are inserted into the corresponding cable receptacle 11 in the cable insertion direction 59. The portions of the cables or wires 81 which extend out of the cable receptacles 11 on the left side of the figure are excess cables 85.

By application of a tool (not shown; e.g. pliers), the lower wire manager module 9a is moved along the first assembly direction 61a and the upper wire manager module 9b is moved along the second assembly direction 61b. The IDC 7 then extends into the cable receptacles 11, thereby cutting an insulation 87 of each cable or wire 81 by means of the IDC blades 53 (see Fig. 1) and at the same time cuts the access cable 85 by means of the cable cutter member 55 (see also Fig. 1). At the same time, the IDC blades contact a core 89 of the cable or wire 81 and establish an electric connection with those. This contacting and cutting takes place for all cables or wires 81, preferably simultaneously.

In Fig. 8, the inventive plug insert 1 is shown in the assembly position 67, in which the excess cables 85 are completely cut and removed. The assembly shown in Fig. 8 may be referred to as the cable termination unit 91

Finally, said cable termination unit 91 may be received in a connector housing 93 along the cable insertion direction 59, thereby forming an inventive connector assembly 95.This is shown in Fig. 9.

It is to be noted that several technical features were introduced with reference to individual figures. Even if they are not explicitly reintroduced in different figures, the corresponding description related to said technical features apply as well to the other figures. Accordingly, symmetric embodiments of the inventive plug insert 1 are shown, wherein a description of an upper portion of the plug insert 1 may be transferred to the lower portion of the same plug insert as well.
