Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in Figure 1, Figure 2 and Figure 3, the present invention provides a push-pull self-locking multi-core high-voltage connector, through the use of the plug and the socket together, after the plug is inserted into the socket, the connection between the socket and the plug can be realized. The function of automatic locking between the two parts effectively avoids the vibration of the connector caused by the unstable external environment, which causes it to fall off from the circuit system, or affects its normal working performance, and safety accidents such as leakage caused by poor contact occur. The safety and stability of the connector during the working process are ensured, and the service life of the connector is prolonged.

Specifically, it includes a multi-core plug 1 and a porous socket 5. The multi-core plug 1 is connected with a number of mandrel pins 2, and a number of jacks 6 are provided on the porous socket 5 at positions corresponding to the mandrel pins 2. When the pin 2 of the mandrel is aligned with the socket 6, and inserted into the socket 6, the connection performance of the multi-core high-voltage connector is realized.

The upper end of the mandrel pin 2 is provided with a connecting seat 3, and one side of the connecting seat 3 is provided with a self-locking fitting 4. The self-locking fitting 4 includes a compression spring 401 and a self-locking rod 402. The connecting seat 3 is connected, and the other end is connected with a vertically arranged hand push plate 403, and one end of the hand push plate 403 away from the compression spring 401 is connected with the self-locking rod 402; the positions on the porous socket 5 close to the jack 6 are vertically arranged The limiting plate 7 is integrally formed with the multi-hole socket 5 , and a locking hole 8 is provided on the limiting plate 7 corresponding to the position of the self-locking rod 402 .

The working principle of the multi-core high-voltage connector to realize the push-pull self-locking function is as follows:

During the process of inserting the mandrel pin 2 into the socket 6, the operator presses the push plate 403 toward the side of the mandrel pin 2, so that the self-locking rod 402 is inserted into the mandrel under the action of the compression spring 401. The direction of the needle 2 is approaching. At this time, the self-locking rod 402 can enter the space formed by the limit plate 7 and the socket 6, and continue to insert the mandrel pin 2 downward until the mandrel pin 2 is completely inserted into the socket. 6, the operator releases the hand push plate 403, under the elastic action of the compression spring 401, the end of the self-locking rod 402 away from the hand push plate 403 can just automatically bounce into the locking hole 8, that is, the multi-core plug 1 is realized. Locking function with multi-hole socket 5.

In the process of inserting the mandrel pin 2 into the jack 6, if the operator does not press the hand push plate 403, at this time, the end of the self-locking rod 402 away from the hand push plate 403 is located on the limit plate 7 away from the jack 6 On the outside of one end, that is, under the blocking of the limiting plate 7, the self-locking rod 402 cannot continue to move downward, so that the mandrel pin 2 cannot continue to be inserted into the socket 6, which will cause the mandrel pin 2 to not move further. It is completely inserted into the jack 6, so that the multi-core high-voltage connector cannot work normally.

If you want to remove the multi-core plug 1 from the multi-hole socket 5, the working principle is as follows:

The operator presses the hand push plate 403 to the side of the mandrel pin 2, so that the self-locking rod 402 approaches the direction of the mandrel pin 2 under the action of the compression spring 401 until the self-locking rod 402 completely comes out of the locking hole 8, At this time, the operator continues to lift the multi-core plug 1 upward until the mandrel pin 2 is taken out from the socket 6, that is, the operation process of removing the multi-core plug 1 from the multi-hole socket 5 is completed.

In this embodiment, the center of the compression spring 401 is horizontally provided with an elastic rubber strip 9 along the axial direction. The elastic deformation ability can also cause corresponding deformation when the operator presses the push plate 403 to deform the compression spring 401. The arrangement of the elastic rubber strip 9 plays a certain role in supporting and stabilizing the compression spring 401, which can avoid When the multi-core plug 1 is in an independent state, it is easy to bend downward due to the force of the push plate 403 and the self-locking rod 402, which will cause wear and tear on the compression spring 401 for a long time, shorten its service life, and make it elastically deformed ability is affected.

The surface of the hand push plate 403 is provided with an insulating protective layer 10. The insulating protective layer 10 is made of polytetrafluoroethylene material and has the ability of insulating protection, which can play a role in safety protection for the operator's operation process, and improves the multi-functionality. The safety and reliability of the core high-voltage connector.

As shown in FIG. 2 , the locking hole 8 is a blind hole, which means that the locking hole 8 does not completely penetrate the limiting plate 7 . In this way, after the self-locking rod 402 is locked into the locking hole 8 , the limiting plate 7 can One end of the self-locking rod 402 plays a blocking role, thereby ensuring the stability of the self-locking, preventing the self-locking rod 402 from passing through one end of the limiting plate 7 and being easily subjected to external forces, making the self-locking rod 402 unstable and affecting the self-locking effect.
