Problems solved by technology

[0002] The electrical connector is a commonly used electrical interface. The threaded electrical connector is a commonly used electrical connector. It includes a plug and a socket. Generally, the socket is equipped with a connecting nut, and the connecting nut is sleeved in an axial direction to prevent movement. On the socket housing, the plug housing is provided with an external thread corresponding to the connecting nut. When the plug and the socket are mated, the two are locked through the cooperation of the connecting nut and the external thread, and the threaded connection It has the advantages of stable connection and good strength, but the structural defects of the thread itself, during the connection process, if the connection torque is too small, it is easy to loosen automatically, and if the connection torque is too large, it is easy to damage the thread profile
In addition, threaded connections take longer to install

Embodiment 1

[0015] Such as figure 1 As shown, a stable and reliable electrical connection mechanism, including plugs and sockets.

[0016] Described socket comprises socket shell 21, nut 22, cylindrical socket insulator 23, and the rear end of described nut 22 is connected with the front end of socket shell 21, and both are coaxial; Socket insulator 23 is positioned at socket shell 21 and Inside the nut 22 , the socket insulator 23 is provided with an insertion hole 24 , and the nut 22 is provided with internal threads.

[0017] The plug includes a hollow cylindrical plug housing 11, a cylindrical plug insulator 12 disposed in the plug housing 11, and pins 13 inserted on the plug insulator 12; the plug housing 11 is also sheathed There is a retaining ring 14, the front end of the outer wall of the retaining ring 14 is provided with a snap ring 141, the rear end of the outer wall of the retaining ring 14 is provided with a connecting thread 16, and the middle section of the outer wall of ...

Embodiment 2

[0020] On the basis of Embodiment 1, the retaining ring 14 is also improved as follows in this embodiment:

[0021] The rear end of the outer wall of the retaining ring 14 is also sleeved with a locking ring 15, and the locking ring 15 is threadedly connected to the section where the connecting thread 16 is located, that is, the inner wall of the locking ring 15 is provided with a thread corresponding to the outer thread of the outer wall of the retaining ring 14. The length of the locking ring 15 is smaller than the length of the connecting thread 16 on the retaining ring 14 in the axial direction of the retaining ring 14, so the locking ring 15 can rotate on the retaining ring 14 and move along the axial direction of the retaining ring 14 . The locking ring 15 has three functions, one is to fix the retaining ring 14, the other is to limit the nut 22, and the third is to further stabilize the connection between the plug and the socket. When the nut 22 of the socket rotates on...

Abstract

A stable and reliable electrical connection mechanism. A plug of the electrical connection mechanism includes a plug shell, and a plug insulator and a contact pin which are arranged in the plug shell; a socket includes a socket shell, a nut connected on the front end of the socket shell, and a socket insulator arranged in the socket shell and the nut, insertion holes are arranged on the socket insulator, and internal threads are arranged on the nut; the plug shell is externally sleeved by a check ring, the front end of an outer wall of the check ring is provided with a snap ring, and the rear end is provided with connection threads; the snap ring and the check ring are coaxial; and the check ring and the snap ring can be clamped in the nut. According to the electrical connection mechanism, the front end of the check ring of the plug is not provided with external threads but is only provided with the snap ring, and in installation, a user only needs to push the check ring into the nut easily, clamp the snap ring in the rear end of the nut, and then turn the nut and the socket by one to two rounds, so that the rear end of the check ring is in threaded connection with the front end of the nut and thus the plug and the socket can be firmly fixed. Compared with a conventional thread connector, the electrical connection mechanism provided by the embodiment is extremely small in required number of winding, and has the advantages of stable connection and fast installation speed.
