In the present invention, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed, mechanically connected, electrically connected, directly connected, indirectly connected via an intervening medium, or in communication between two elements or in an interaction relationship between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

The core of the present invention is to provide a socket housing 11, a socket 1, a plug 2 and a connector, and the specific structure of the socket, the plug and the connector will be described below.

< Socket >

Referring to fig. 1 to 6, the socket 1 includes a socket housing 11 and a socket contact 12 mounted in the socket housing 11, and the socket housing 11 includes a flange 111 matched with the mounting surface plate and a socket portion 112 formed by extending the flange 111 forward, and a curved groove 1122 and an identification key slot 1121 are circumferentially distributed on an outer circumference of the front end of the socket portion 112, where the curved groove 1122 can be matched with the clip 23 on the plug 2 to realize the locking of the header, and the identification key slot 1121 is used for judging whether the socket can be matched with the corresponding identification key 25 on the plug 2.

It should be noted that, at least one crank groove 1122 and at least one identification key groove 1121 are provided, and in the prior art, three crank grooves 1122 are generally provided to ensure the locking effect of the headstock after the crank grooves 1122 are matched with the staples 23. When the number of the identification key grooves 1121 is one, the determination accuracy is generally low because of the small number of the identification key grooves, although the determination can be made as to whether the plug 2 to be inserted is matched. Preferably, at least two identifying key slots 1121 are circumferentially arranged on the outer wall of the front end of the plugging portion 112 at intervals, and more preferably, the width of the identifying key slots 1121 and/or the diameter of the circle where the bottom wall is located are defined, wherein the widths of the identifying key slots 1121 along the direction perpendicular to the extending direction of the socket housing 11 are identical or not identical or are completely different. The bottom walls of the plurality of identification key slots 1121 are the same or not the same or different from the center of the socket 1. When the width of the recognition key groove 1121 and/or the diameter of the circle in which the bottom wall of the recognition key groove 1121 is located are the same, although it is also possible to judge whether the plug 2 to be inserted is matched, the judgment accuracy is not very high. When the width of the recognition key slot 1121 and/or the diameter of the circle where the bottom wall of the recognition key slot 1121 is located are set to be not identical or completely different, not only the misplug of the connector itself in the axial direction but also the misplug between the connector and the connector can be prevented, and simultaneously the rotation of the opposite plug 2 to the correct plug angle and position can be ensured, and the damage to the contacts in the plug 2 and the socket 1 due to the mismatching of the plug angle and the plug position can not exist.

The invention arranges the locking curved groove 1122 and the identification key groove 1121 on the outer circumference of the socket shell 11, thereby realizing the integral easy cleaning of the socket 1 and solving the problem that the existing socket structure is only partially easy to clean.
