Description:
CONNECTING MEMBER OF COIL ASSEMBLY AND COIL ASSEMBLY

Field of the Invention

[0001] The present invention relates to a connecting member for connecting a coil assembly as well as the coil assembly, and particularly to a connecting member for connecting a coil assembly for use in a control system of an anti-lock braking system as well as the coil assembly.

Background of the Invention

[0002] Coil assemblies are devices applied extensively. For example, the control system of anti-lock braking system mounted in a motor vehicle comprises a control member, an actuating member and a hydraulic assembly. Atypical control member is a coil assembly. The actuating member comprises a printed circuit board PCB. Both the coil assembly and the PCB of the control system of the anti-lock braking system are usually mounted in a housing and are connected together via connecting terminals.

[0003] Connecting terminals for connecting the PCB to the coil assembly in the prior art have the following problems. First, it wastes material and causes higher costs. In the prior art, generally two kinds of connecting terminals are used to mount the coil assembly, wherein one kind of terminal is used for fixing the coil assembly to the housing and the other kind of terminal is used for welding the coil assembly with the PCB. Secondly, the connecting terminal in the prior art is complicated in process. Currently, the connecting terminal is connected with a framework of the coil assembly mostly by injection molding, and the connecting terminal is connected and communicated with an enameled wire of the coil via welding. Thirdly, the anti-shock effect is inconspicuous. A stress generated by shock is likely to cause damage to the structure of the connecting terminal, especially for the connecting terminal in the anti-lock braking system of the motor vehicle, since constant shock certainly exists during travel of the motor vehicle, there are particularly high requirements for resistance against shock of the connecting terminal. Furthermore, a high requirement is imposed on precision of dimensions of the connecting terminal. If the dimensions deviate, it will not only cause difficulty in mounting the connecting terminal but also tend to generate stress, which causes a shorter service life of the connecting terminal and an increase of the mounting costs for the coil assembly of the connecting terminal. [0004] It is desirable to provide an improved connecting terminal for connecting the coil assembly, which can solve the above problems with the connecting terminals in the prior art, and to provide a coil assembly which has the above improved connecting member.

Detailed Description of Preferred Embodiments

[0042] Various specific embodiments are described with reference to the accompany drawings forming part of the specification. It should be appreciated that although terms indicative of directions such as "front", "rear", "up" and "down" are used in the specification to describe various example structural portions and elements of the present utility model, use of these terms is only for purpose of easy description and determined based on orientations of examples shown in the figures. Since the embodiments disclosed in the present utility model can be arranged according to different directions, these terms indicative directions are used only for illustration purpose and should not be considered as limiting the utility model. In possible cases, the same or like reference numbers used in the present utility model designate the same members.

[0043] Fig. 1 shows a control system of an anti-lock braking system in which a coil assembly according to an embodiment of the present utility model is mounted. A coil assembly 1 is mounted in a cavity formed on one side of a bottom of a housing 2. Fig. 8 shows a perspective view of the other side of the bottom of the housing for mounting a PCB board (not shown in the figure) opposite to the coil assembly 1, and shows connecting terminals of the duly-mounted coil assembly 1. The description is presented by taking the coil assembly applied to the control system of the anti-lock braking system as an example, but it should be appreciated that the coil assembly and connecting member disclosed in the present utility model may be applied to other occasions. [0044] Fig. 2 shows a specific structure of the coil assembly 1 of Fig. 1. For illustration purpose, the coil assembly in Fig.2 is inverted as compared with the coil assembly 1 shown in Fig. 1. The coil assembly 1 comprises a coil member 3, the coil member 3 comprises a coil housing 4 and a coil 5 (not shown) mounted in the coil housing, the coil housing 4 is provided with two connecting terminal mounting brackets 6a and 6b for mounting a connecting terminals 10a and 10b, the coil 5 is usually formed by winding an enameled wire including two wire ends 5 a and 5b respectively provided on the mounting brackets 6a and 6b. As such, when the connecting terminals 10a and 10b are respectively mounted on the mounting brackets 6a and 6b, the connecting terminals are connected to the enameled wire ends, and electrical communication between the connecting terminals and the wire ends may be further achieved in various manners. Alternatively, as shown in the figure, in an upper portion of each of the mounting brackets 6a and 6b is provided a passage for receiving the connecting terminal such that the connecting terminal may be mounted and fixed on the coil member by way of being inserted into the passage. The two wire ends 5a and 5b of the coil 5 are respectively mounted on the upper edge of the mounting brackets 6a and 6b. To more firmly fix the wire ends on the mounting brackets, recesses 7a, 7b are provided in the upper portion of the mounting brackets as shown in the figure so that the enameled wire is provided across the mounting brackets 6a and 6b and at a bottom of the recesses 7a, 7b.

[0045] Fig. 3 is a sectional view of the coil assembly 1 shown in Fig. 2 and shows the coil 5 mounted in the coil housing. For the sake of clarity and brevity, Fig. 3 only shows one mounting bracket 6a and one connecting terminal 10a. The mounting bracket 6b and the connecting terminal 10b may have the same structure.

[0046] Fig. 4 is a sectional view of the coil assembly 1 shown in Fig.2 with one mounting bracket being sectioned. For the sake of clarity and brevity, Fig. 4 also only shows one mounting bracket 6a and one connecting terminal 10a. The mounting bracket 6b and the connecting terminal 10b may have the same structure. Fig. 4 more clearly shows a connection relationship between the connecting terminal 10a and the mounting bracket 6a after the connecting terminal 10a is inserted into the mounting bracket 6a through the passage on the mounting bracket, particularly the enameled wire 5 a (5b) is provided across the mounting bracket 6a (and 6b) and at the bottom of the recess 7a (and 7b). [0047] As will be described hereafter in more detail, the mounting bracket cooperates with the connecting terminal disclosed in the present utility model to achieve an excellent technical effect.

[0048] Fig. 5 and Fig. 6 show a specific structure of the connecting terminal 10a according to an embodiment of the present utility model. The connecting terminal 10b has the same structure. The connecting terminal 10a comprises connecting ends 100a and 200a, wherein the connecting end 100a is electrically connected with the enameled wire end 5 a, and the connecting end 200a is to be connected with a PCB of the control system of the anti-lock system. The connecting ends 100a and 200a may be configured to extend parallel to each other in opposite directions.

[0049] Between the connecting ends 100a and 200a is provided a transverse arm 300a extending transversely. The transverse arm 300a is provided with a curved portion 320a which is wholly in a shape of Greek letter Omega (Ω). The curved portion 320a has an arch-like portion 322a and two ends 321a and 323a. In the present utility model, "a curved portion which is wholly in a shape of Greek letter Omega" refers to a structure having two ends and an arch-like connecting portion between the two ends, wherein the arch-like connecting portion has a structure starting from both ends and extending towards outside the both ends first and then extending towards inside the both ends. The curved portion is not limited to a shape completely identical with Greek letter Omega (Ω) and not limited to the specific shapes as shown in the figures. A plane where the curved portion 320a lies is substantially perpendicular to an extension direction of one of the connecting ends 100a and 200a.

[0050] The curved portion 320a which is wholly in the shape of Greek letter Omega achieves an advantageous effect of enhancing anti-shock performance of the connecting terminal. Upon shock, a force that might damage the structure of the connecting terminal occurs. The shock may be effectively reduced and the service life of the connecting terminal may be prolonged through deformation of the curved portion. Furthermore, the curved portion 320a which is wholly in the shape of Greek letter Omega further effectively reduces requirements for precision of dimensions of the connecting terminal. This at least brings about the following advantages. When the dimensions of the connecting terminal deviate to some degree (e.g., a distance between the two connecting ends 100a and 200a does not comply with a standard precision), it will become difficult to mount the connecting terminal at a predetermined portion to connect the coil assembly and the PCB. Even though the connecting terminal is mounted in place, a stress is apt to occur and cause damage to the connecting terminal. The curved portion 320a is provided to compensate the above deviation of dimensions and thereby solve the problem that in the event of dimension deviation the connecting terminal is hard to mount and a stress damaging the structure of the connecting terminal might occur. Furthermore, it is found that the curved portion which is wholly in the shape of Greek letter Omega achieves a particularly prominent effect in solving the above technical problem. These advantages are especially effective when the connecting terminals are applied to the control system of the anti-lock braking system where the connecting terminals have to endure constant and strong shocks and need to be positioned on the housing for connection with the PCB.

[0051] The transverse arm 300a further comprises connecting arms 310a, 330a, 350a and 370a. The connecting arm 310a extends substantially in a vertical direction, with a lower end connected to the end 321a of the curved portion 320a and an upper end connected to one end of the connecting arm 350a. The connecting arm 350a extends transversely towards the connecting end 100a. The other end of the connecting arm 350a is connected to the connecting end 100a. Similarly, the connecting arm 330a extends substantially in a vertical direction, with a lower end connected to the end 323a of the curved portion 320a and an upper end connected to one end of the connecting arm 370a. The connecting arm 370a extends transversely towards the connecting end 200a. The other end of the connecting arm 370a is connected to the connecting end 200a. As such, the transverse arm 300a is integrally connected with the connecting ends 100a, 200a.

[0052] In the above embodiment, the connecting arms 310a and 330a extend in the same direction, but they may extend in different directions, for example, one of the connecting arms 310a and 330a extends upwardly while the other extends downwardly. In addition, the arrangement that the connecting terminal 10a in the above embodiment is provided with the vertically- extending connecting arms 310a and 330a may reduce a force acting on the curved portion 320a upon shock so that the structure of the connecting terminal is firmer. However, the arrangement that the both ends 321a and 323a of the curved portion are connected to the connecting ends 100a and 200a directly via the connecting arms 350a and 370a without help of connecting arms 310a and 330a also falls within the scope of protection of the present utility model. The transverse arm 300a and connecting ends 100a, 200a may be an integrally- formed single member, for example a stamped member, so that the connecting terminal can be easily processed and manufactured with lower costs.

[0053] A lower end 120a of the connecting end 100a is formed with two opposite legs 121a and 123 a with a slot 122a formed therebetween. As such, when the connecting end 100a is inserted into the passage of the mounting bracket 6a, the slot 122a clamps the enameled wire disposed on the bottom of the recess 7a. A width of the slot 122a is set to form insulation removal contact with the enameled wire, i.e., while the slot 122a clamps the enameled wire, the slot 122a destroys an insulating layer outside the enameled wire so that electrical communication is achieved between the wire end of the coil and the legs of the connecting end.

[0054] A barb structure 110a is provided on each of opposite lateral sides of the connecting end 100a. Preferably, the barb structure 110a is at least disposed at the outer side of the two legs 121a and 123 a. As such, when the connecting end 100a is inserted into the passage of the mounting bracket 6a, the barb structure 110a and the mounting bracket 6a form an interference fit so that the connecting end 100a may be firmly fixed in the mounting bracket 6a without injection molding.

[0055] The barb structure of the connecting end 100a enables the connecting terminal 10a to be conveniently mounted on a frame of the coil member and firmly fixed thereon without injection molding, which simplifies the mounting process of the connecting terminal and may effectively reduce damage to the enameled wire caused by the high temperature of the injection molding. Electrical connection between the connecting terminal and the coil wire end can be automatically achieved only by inserting the connecting terminal 10a into the mounting bracket with aid of the slot between the legs, thereby simplifying the process, avoiding conventional welding and lowering the costs.

[0056] A barb structure 210a is provided on each of opposite lateral sides of the connecting end 200a. At a predetermined position of the bottom of the housing 2 is provided a through hole (not shown) allowing the connecting end to pass therethrough. When the coil assembly 1 is mounted in the housing 2, the connecting terminal passes through the bottom of the housing via the through hole. The barb structure 210a and the through hole form an interference fit so that the connecting terminal 200a is firmly fixed in the housing. Such connection mode may simplify the structure of a mold for molding the housing and effectively ensure position degree of the connecting terminal. An end 220a of the connecting end 200a has a press-fitting structure which forms a press-fitting connection with the PCB.
