Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the present invention provides a quick-locking electrical connector, including: a socket 100 and a plug 200; the socket 100 includes: a socket housing 101, a socket insulator 102, and a socket center pin 103; the plug 200 includes: a plug housing 201, a plug body 203, and a shield assembly, a center pin 209, an insulator assembly, and a seal assembly disposed within the plug body.

In this embodiment, as shown in fig. 3 and 4, the plug housing 201 is slidably disposed on the plug main body 203, the plug main body 203 is axially provided with an annular groove 231 for abutting against the socket housing 101, a radial annular limiting groove 232 is disposed on a groove wall of the annular groove 231, an elastic limiting ring 202 (C-shaped limiting ring) having an opening is disposed in the annular limiting groove 232, the elastic limiting ring 202 is provided with a control inclined surface 221 and a limiting end surface 223, the socket housing 101 is provided with a locking portion 104, when the plug 200 is inserted into the socket 100, the socket housing 101 extends into the annular groove 231, and the locking portion 104 and the limiting end surface 223 form a limiting fit.

Referring to fig. 1, the plug housing 201 is provided with a control portion 234 extending into the annular groove 231 and abutting against the control inclined surface 221, and when the plug housing 201 is slid, the control portion 234 presses the control inclined surface 221 to deform the elastic limiting ring 202 and disengage from the locking portion 104 to unlock the socket 100. The control portion 234 is tightly pressed against the control inclined surface 221, and can control the deformation of the elastic limiting ring 202, and can also play a role of limiting the elastic limiting ring 202 in the annular limiting groove 232 when not stressed.

In this embodiment, as shown in fig. 4, the elastic retainer 202 is further provided with a sliding surface 222 so that the front end of the socket housing 101 can be pressed in. When the plug 200 is inserted into the socket 100, the socket housing 101 is inserted through the annular groove 231 and presses the sliding surface 222 of the elastic limiting ring 202, so that the elastic limiting ring 202 moves into the annular limiting groove 232, and when the front locking portion 104 of the socket housing 101 exceeds the limiting end surface 223 of the elastic limiting ring 202, the elastic limiting ring 202 recovers deformation by virtue of the elastic force thereof and locks the locking portion 104.

In this embodiment, as shown in fig. 4, a part of the position-limiting end surface 223 of the elastic position-limiting ring 202 is located in the annular position-limiting groove 232, and a part of the position-limiting end surface protrudes out of the annular position-limiting groove 232. One part of the limiting end surface 223 is positioned in the annular limiting groove 232, so that the self positioning and fixing can be realized, the limiting end surface is prevented from sliding out of the annular limiting groove 232, and the other part of the limiting end surface protrudes out of the annular limiting groove 232 to form the main part of the locking socket.

In this embodiment, as shown in fig. 1 or fig. 2, the locking portion 104 is a limiting boss disposed at a position corresponding to the limiting end surface 223 at the front end of the socket housing 101. Of course, the locking portion 104 may also be a limiting slot disposed at the front end of the socket housing corresponding to the position of the limiting end face. The limiting boss or the limiting clamping groove can provide a limiting surface matched with the limiting end surface 223, and then the locking purpose is achieved.

In this embodiment, as shown in fig. 2 and 3, the sealing assembly includes a first sealing ring 208 disposed on the plug main body 201 for sealing with the socket housing 101. The first sealing ring 208 ensures that the plug and the socket are waterproof after being inserted.
