The present utility model relates to a connector for quick connection and disconnection, is of the kind provided with a pin and a socket, and which permits the connection between the conductors of similar diameter by means of quick and efficient action of fitting the pin to the socket.

Connectors of this kind, especially those which are designed for high currents that utilize the inventive concept of the pin and socket, are already well known in the art.

However, said connectors of the prior art present the disadvantage of utilizing welding systems or the traditional mounting (assembly) systems by means of threads for effecting the connection and disconnection operations, which are time consuming and require such specific appliance tools as, for example, welding machines, conformation pliers, etc.

Therefore, it is desirable that a connector be developed for effecting connection and disconnection operations which does not utilize specific appliance tools, and, further, which provides a quick and simple solution for the easy installation and removal of the conductors. This purpose is achieved by means of the development of a connector that presents separate prongs and provides a spring action suitable for the connection and disconnection of conductors that results in a stabilized electrical connection.

Detailed Description

The connector 1 for quick connection and

disconnection of the present invention is basically comprised of two main parts, a male element 3 and a female element 3 and further, of two screw nuts 4 and a coiled spring 5 that is used in the outer diameter of the connection pin 6 of the male element 2 to facilitate the assembly of the connector 1 of the present invention and effect the electrical connection between the female and male elements of the connector 1. The screw nut 4 presents separate prongs which provide a spring effect suitable for this kind of connection, guaranteeing the electrical performance of same, as it usually works with frequent increases and drops in temperature.

The male element 2 presents in one of its ends a connecting pin 6 and in the other end clamps 9.

Additionally, the male element 2 presents a threaded part 10 where screw nut 4 will be joined and further presents two plane faces 13 wherein a spanner wrench used is to fix the male element when tightening screw nut 4.

The female element 3 presents end clamps 11, a threaded part 12 where screw nut 4 will be joined and further, a cylindrical receptacle 13 for receiving male element 2, more precisely connecting pin 6, mounted on spring 5. Furthermore, said female element 3 presents two place faces 14 wherein a spanner wrench is used to fix the male element when tightening screw nut 4.

For the application of connector l of the present invention it is necessary to adjust conductors 8 which will be connected, in the interior of clamps 9 and 11 of each male element 2 and female element 3 and further it is necessary to thread screw nut 4 which will have a springlike effect on clamps 9, 11 of male element 2 and female element 3 when tightening screw nut 4 by means of a common spanner.

The screw nut 4 was designed so as to function as a spring by the action of its prongs 7 over clamps 9 and

11 of the male element 2 and female element 3 against conductors 8, which permits a stabilized electrical connection.

Thus, conductors 8 are firmly fixed to connector 1 for the present invention providing an excellent mechanical and electrical connection.

Referring now to Figs. 8-9, a further embodiment of the present invention will be described. Fig. 8 shows electrical connector l' having a male element 2', a nut 4, prongs 7, conductor 8, and end clamps 9. Male element 2' includes a spring element 5 disposed in an annular 26 groove thereof. Electrical connector 1' also includes receptacle 13' with plane faces 14, locking grooves 22,24, end clamps 11, and nut 4 with prongs 7 for connection to conductor 8. Electrical connector 1' also includes a spring locking member 20 having lock arms 20a and a handle section 20b. Spring locking member 20 is shown prior to insertion into locking grooves 22,24 wherein lock arms 20a will each be received within a respective locking groove 22,24.

Grooves 22,24 are cut into receptacle member 13' so that when male element 2' is inserted into the receptacle 13', annular groove 26 will be aligned with locking grooves 22,24. As shown in Fig. 9, lock arms 20a will be received in a respective locking grooves 22,24, the cross section of which is shown in Fig. 9. Part of each locking arm 20a will protrude out of annular groove 26 so that they will be aligned for engagement with a respective portion of receptacle 13'. Forces tending to separate the receptacle from the male element 2' as shown by arrow "A" and arrow "B" will result in a shearing force directed by receptacle 13' and male element 2' against the lock arms 20a of spring locking member 20. Spring 5 of electrical connector 1' provides metal to metal contact between itself and the male element 2' and receptacle 13'.

Although two specific embodiment of the present

invention are herein described for a better understanding, it should be clear to those skilled in the art that numerous variations of details may be effected without departing from the scope of the invention, as defined in the attached claims.
