Referring to fig. 3 and 5, the plug includes a plug pin 21, a plug insulator 22, and a plug housing 23; the plug insulator 22 is sleeved on the plug pin 21, and the plug shell 23 is sleeved on the plug insulator 22; the front end of the bolt 21 is in a round table shape or a cone shape, and the tail end is connected with the second cable. Referring to fig. 4 and 5, the socket includes a socket 11, a socket insulator 12, a socket housing 13, and an elastic member; the front end of the inner cavity of the plug bush 11 is matched with the front end of the plug pin in shape, and the tail end of the plug bush 11 is connected with a first cable; a second limiting step 17 is arranged on the outer side surface of the plug bush 11, the second limiting step 17 is positioned at the front end or the front part of the plug bush 11, a first limiting step 16 is arranged on the inner side of the socket insulator 12, the plug bush 11 penetrates through the first limiting step 16 to be connected with the socket insulator 12 in a sliding mode, and the elastic element is positioned in a first cavity formed by the socket insulator, the first limiting step, the plug bush and the second limiting step; the socket housing 13 is fitted over the socket insulator 12.
When the plug is used, the plug is inserted into the plug bush when the plug is inserted into the socket, the plug bush is pushed to move along the axis of the plug bush, and the plug bush are pressed tightly under the action of the spring to generate reliable contact force. Meanwhile, the contact surface between the plug pin and the plug bush is large, so that the contact resistance can be effectively reduced, and the truncated cone-shaped or conical plug pin is stable and not easy to damage. The invention does not limit the forms of the plug shell and the plug bush shell, and only needs to adopt the existing plug shell and the plug bush shell.
In an alternative embodiment of the present invention, referring to fig. 3 and 4, the latch further includes a second retaining ring 24; a third limiting step 25 is arranged on the inner side surface of the plug insulator 22; the tail end of the bolt 21 is provided with a limit step IV 26, and the middle part is provided with a retaining ring II mounting groove; the plug pin passes through the third limit step 25 and is fixed in the plug insulator 22 through the second retainer ring 24.
In an alternative embodiment of the invention, see fig. 4, the front end of the latch 21 is truncated cone shaped.
In an alternative embodiment of the invention, see fig. 3, the socket further comprises a first collar 15. The second limiting step 17 is located at the front end of the plug bush 11, a first retaining ring mounting groove is formed in the outer side face of the middle of the plug bush 11, a first retaining ring 15 is mounted on the first retaining ring mounting groove, and the first retaining ring 15 and the second limiting step 17 are located on two sides of the first limiting step 16 respectively. The first check ring is C-shaped and made of stainless steel.
In an alternative embodiment of the invention, see fig. 4, the resilient member is a spring 14. When the bolt is used, a proper spring can be selected according to requirements, so that the pressing force of the spring can ensure that the plug bush and the bolt are kept in contact effectively under the condition of vibration or impact.
In an alternative embodiment of the invention, the plug housing comprises a plug housing inner layer and a plug housing outer layer; the inner layer of the plug shell is fixedly connected with the outer layer of the plug shell; the cavity between the inner layer of the plug shell and the outer layer of the plug shell is used for plugging the socket shell.
In an alternative embodiment of the invention, the receptacle housing exterior and the receptacle insulator exterior are not adjacent, and the cavity between the receptacle housing exterior and the receptacle insulator exterior is used to mate the plug housing and the plug insulator.
