And two pins 6 extend out of the socket insulator 5 to form two external terminals A and B.

The socket insulator 5 is also internally provided with an elastic piece 4 which stretches along the axial direction and a fixing piece for fixing the socket insulator 5 on equipment. In the embodiment of the invention, the elastic part 4 is a spring, the fixed part is a screw 3, the two springs and the two screws are symmetrically distributed on two sides of the two contact pins 6, and the spring is sleeved on the screw to realize the guiding of axial floating.

In the embodiment of the invention, in order to prevent the socket 1 from loosening on the equipment, a flat washer 7 and a spring washer 8 are further arranged between the screw 3 and the socket insulator 5, wherein the flat washer 7 is pressed on the tail end face of the socket insulator 5, and the spring washer 8 is positioned between the flat washer 7 and the screw 3, so that an elastic force is generated between the screw 3 and the socket insulator 5 to keep the screw stable.

The plug 1 comprises a plug insulator 11 at the front end and a push rod insulator 9 at the rear end, wherein the push rod insulator 9 is matched with at least one locking platform 14 on the periphery of the push rod insulator and a locking groove 13 extending along the axial direction on the socket insulator 5 to realize the axial backward limiting between the plug and the socket, and at the moment, one end of the elastic element 4 is pressed on the socket insulator 5, and the other end of the elastic element is pressed on the push rod insulator 9 to provide axial separation force for the socket insulator 5 and the push rod insulator 9.

The connector has a short-circuit state and an open-circuit state, when no external force exists, the inserting pins and the inserting holes are separated from each other under the axial opposite elastic force provided by the elastic piece 4, and at the moment, the socket insulator 5 and the push rod insulator 9 are axially limited by the matching of the locking platform 14 and the locking groove 13 to prevent the two from being separated from each other. At this time, the two pins 6 disposed in the socket insulator 5 are not in contact with the two insertion holes 12 in the plug insulator 11, and the two external connection terminals a and B are in an open circuit state, i.e., a normally open state.

When the push rod insulator 9 of the plug compresses the elastic element 4 to move towards the socket insulator 5 under the action of external force, the two jacks 12 in the plug insulator 11 also move towards the two pins 6, so that the two jacks 12 are in contact conduction with the two pins 6, and at the moment, a short circuit state is formed between the two external connection end points A and B, namely a normal working state.

And the bent contact pin 6 is integrally U-shaped, so that the connector and the printed board can be conveniently welded.

The connector for realizing the switching function can be applied to a modular connector case to realize the independent control of each module power circuit in the case, and each module is correspondingly provided with the connector for realizing the switching function.

In particular, the modular connector comprises a chassis 21 provided with a modular jack 24 on the bottom plate and a plurality of modules 25 fitted inside the chassis, each module end being provided with a modular plug 26 for cooperation with the modular jack 24. The bottom of the chassis 21 is further provided with a printed board 23 for connecting with the tail of each module socket 24, the printed board 23 is connected with a main power switch 28 on the chassis 24 through an internal wire, and is communicated with an external power inlet 27 through the main power switch 28. The printed board 23 distributes power to the power contacts of the respective modular jacks through internal wiring thereof. The connector for realizing the switching function is arranged on the bottom plate of the case 21, so that the on-off of the power supply circuit corresponding to each module socket on the printed board 23 is realized.

Specifically, the connector for realizing the switching function is fixed at the bottom of a chassis base plate 22 through a screw 3, and is connected with a power circuit of a corresponding module on a printed board through a part of the tail part of a contact pin 6 extending out of a socket insulator 5, and is used as a switch on the power circuit of the module to realize the on-off of the power circuit of the module. At the moment, the rear end face of the plug end push rod insulator 9 plugging part is contacted with the end face of the chassis base plate, the force application part penetrates through the chassis base plate and extends into the chassis, and can move towards the socket 2 end under the pushing of the module 25 when the module 25 is plugged, and when the module plug and the module socket are plugged in place, the connector for realizing the switching function is also plugged in place at the same time, so that a power circuit of the module is conducted, namely the connector for realizing the switching function is synchronously plugged with the chassis connector. And when the module connector is separated, because of the existence of the spring 4, the connector plug realizing the switching function is also separated from the socket along with the separation of the module 25, and when the module plug and the module socket are completely separated, the contact pin and the jack of the connector realizing the switching function are also completely separated, so that the power supply of the module is disconnected. Preferably, two terminals of the connector for implementing the switching function are connected to a + pole circuit of the module power supply circuit.
