Plug insulator in housing and the contact pin being plugged on plug insulator；The socket includes Socket casing, is connected to socket
The nut of housing forward end, the socket insulator being arranged in Socket casing and nut, the nut and Socket casing are coaxial, described
Jack is provided with socket insulator, internal thread is provided with the nut；Back-up ring, the gear are also arranged with outside institute's plug casing
Ring outer wall front end is provided with snap ring, and rear end is provided with connection screw thread；Snap ring is coaxial with back-up ring；The back-up ring and snap ring can be caught in
In nut.
As a further improvement on the present invention, the back-up ring outer wall rear end is also arranged with retaining ring, the length of the retaining ring
Degree can be rotated less than length and retaining ring of the connection screw thread on back-up ring axial direction on back-up ring on back-up ring and the axial direction along back-up ring
It is mobile.
As the another improvement of the present invention, the back-up ring is made up of the curved baffle plate split in two cross sections, two gears
The center of circle of plate overlaps and has gap between two baffle plates.
Further, the retaining ring outer wall is provided with latch.
Further, the pitch of the internal thread of the connection screw thread and nut is not less than 1.75.
To sum up, the beneficial effects of the invention are as follows：The present invention is not provided with external screw thread in plug back-up ring front end and only sets a card
Ring, during installation, user is only needed back-up ring being easily pushed into nut, and snap ring is caught in the rear end of nut, and nut and socket are turned again
Dynamic one to two circle, plug and socket can be securely fixed by back-up ring rear end is connected with nut nose threads.With traditional screw thread
Connector is compared, and winding number needed for the electrical connection mechanism of the present embodiment is few, therefore not only plug and socket stable connection, and
And installation rate is fast.

Embodiment
The present invention will now be described in further detail with reference to the accompanying drawings and the accompanying drawings, but embodiments of the present invention
Not limited to this.
Embodiment 1：
As shown in figure 1, reliable and stable electrical connection mechanism, including plug and socket.
The socket includes Socket casing 21, nut 22, columned socket insulator 23, and the rear end of nut 22 is with inserting
The front end of seat shell body 21 is connected, and the two is coaxial；Socket insulator 23 is located in Socket casing 21 and nut 22, the socket insulator
Jack 24 is provided with 23, internal thread is provided with the nut 22.
Plug casing 11, the columned plug being arranged in plug casing 11 that the plug includes hollow cylindrical are exhausted
Edge body 12 and the contact pin 13 being plugged on plug insulator 12；Back-up ring 14, the back-up ring 14 are also arranged with outside institute's plug casing 11
Outer wall front end is provided with snap ring 141, the outer wall rear end of back-up ring 14 is provided with connection screw thread 16, the outer wall stage casing of back-up ring 14 is smooth and does not set
Put any part.Snap ring 141 and back-up ring 14, plug casing 11 are coaxial, and snap ring 141 is close to the setting of the outer wall of back-up ring 14.Connection
Screw thread 16 is engaged with the internal thread of nut 22；The back-up ring 14 and snap ring 141 can be caught in nut 22, and back-up ring 14 is caught in spiral shell
When in cap 22, connection screw thread 16 is threadedly coupled with nut 22；The back-up ring 14 is by the curved baffle plate in two cross sections with recess
Relative mode split is formed, and the structure after split is as shown in figure 1, the center of circle of two baffle plates overlaps and had between two baffle plates
Gap is to have gap between two relative sides of baffle plate.
In the present embodiment, the front end of back-up ring 14 is not provided with external screw thread and only sets a snap ring 141, and during installation, user only needs
Back-up ring 14 is easily pushed into nut 22, between the two neighboring helix for the rear end that snap ring 141 is caught in nut 22, by nut 22
And socket is rotated further by one to two circle, the rear end of back-up ring 14 is connected with the nose threads of nut 22 can be firmly solid by plug and socket
It is fixed.Compared with traditional screw thread coupling, winding number needed for the electrical connection mechanism of the present embodiment（That is the turning collar of nut 22
Number）Seldom, therefore not only plug and socket stable connection, and installation rate is fast.
Embodiment 2：
On the basis of embodiment 1, also back-up ring 14 is improved as follows in the present embodiment：
The outer wall rear end of back-up ring 14 is also arranged with retaining ring 15, and the retaining ring 15 is threaded in the institute of connection screw thread 16
It is to be provided with the internal thread being engaged with the external screw thread of the outer wall of back-up ring 14, the length of retaining ring 15 on the inwall of retaining ring 15 in section
Less than the length on back-up ring 14 on the axial direction of 16 back-up ring of connection screw thread 14, therefore, retaining ring 15 can be rotated on back-up ring 14 and edge
The axial movement of back-up ring 14.The effect of retaining ring 15 has 3, first, fixed back-up ring 14, second, nut 22 is carried out it is spacing, third,
Further make plug and socket stable connection, can be by retaining ring 15 when the nut 22 of socket is being rotated in place on back-up ring 14
Moved to the direction of the front end of back-up ring 14, compress back-up ring 14.When the connection of plug and socket is very stable, adjustment can not had to
