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

[0016] The plug of the present invention is used in conjunction with a socket with a screw cap. The general structure of the socket with screw cap in the prior art is as figure 2 Shown:

[0017] 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.

[0018] The structure of the quick installation type plug-in mechanism of the present invention is as follows: figure 1 As shown, it includes a hollow cylindrical plug housing 11, a cylindrical plug insulator 12 disposed in the plug housing 11, and a pin 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 retai...

Embodiment 2

[0021] On the basis of Embodiment 1, the retaining ring 14 is also improved as follows in this embodiment:

[0022] 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 during installation, and the third is to further stabilize the connection between the plug and the socket. When rotating in pl...

Abstract

Provided is a quick installation type connecting mechanism, comprise a plug casing, a plug insulator arranged in the plug casing, and pins embedded in the plug insulator. The plug casing is also sleeved by a back-up ring; the outer wall front end of the back-up ring is provided with a snap ring which is coaxial with the back-up ring, and the rear end is provided with connecting threads. The front end of the back-up ring of a plug is not provided with external threads but only provided with the snap ring, and only the rear end is provided with connecting threads. In installation, a user only needs to easily push the back-up ring into a nut of a matching socket, clamp the snap ring into the rear end of the nut, and rotate the plug for one to two circles relative to the matching socket to realize threaded connection between the rear end of the back-up ring and the nut front end of the matching socket so as to firmly fix the plug and the socket. Compared with a traditional thread connecting device, the plug requires extremely less coiling in installation, and has the advantages of stable connection and fast installation.
