Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example one

As shown in fig. 1 to 3, the present embodiment provides a socket protection door structure, which is applied to a sliding rail socket 1 with two holes. The socket protection door structure is integrally installed right below two jacks 11 of the socket 1 and comprises a support frame 2, a spring 3 and two sliding modules 4. The support frame 2 is a long-strip box body with an opening at the upper end. The middle of two side walls of the bracket frame 2 is provided with a convex column 22, the inner wall of the shell 12 of the socket 1 is provided with a corresponding round hole, the convex column 22 is inserted into the round hole to form rotary connection, and the bracket frame 2 can swing and rotate around the convex column 22 at two sides. The rib plates are arranged below the support frame 2 to limit the rotation angle of the support frame 2 to a certain degree, so that excessive rotation is prevented. Two through holes 21 are arranged at the bottom of the support frame 2, and the shapes and the positions of the through holes 21 correspond to those of the jacks 11.

Two sliding modules 4 are symmetrically arranged at two ends in the support frame 2 and are respectively positioned between a group of corresponding through holes 21 and the jacks 11, and the spring 3 is positioned between the two sliding modules 4, and two ends of the spring are respectively connected with one sliding module 4. The side walls of the two sides of the support frame 2 are provided with sliding grooves 23, the two sides of the sliding module 4 are provided with flanges 41, and the flanges 41 are inserted into the sliding grooves 23 to form sliding connection. Specifically, the method comprises the following steps: the insertion hole 11 of the socket 1 in the present embodiment is a square and circular composite insertion hole, and thus the slide module 4 includes the first slider 4a and the second slider 4 b. The upper ends of the first slider 4a and the second slider 4b are both provided with inclined surfaces which are both inclined toward the end of the holder frame 2 and in a direction away from the insertion hole 11. The back of the first sliding block 4a is also provided with an installation groove, and one end of the spring 3 is embedded into the installation groove; the first slide block 4a is positioned below the square hole of the square and round composite jack. The second slider 4b is positioned between the first slider 4a and the end of the holder frame 2; and the second slider 4b is located below the circular hole of the square-circular composite jack.

The working principle of the embodiment is as follows:

when the plug is normally inserted into the socket, there are two cases:

1) when the square plug is inserted into the square hole, the first sliding blocks 4a positioned on the two sides of the support frame 2 are stressed uniformly, and under the action of the plug and the inclined plane, the first sliding blocks 4a on the two sides compress the springs 3 to move towards the middle of the support frame 2, so that the through holes 21 exposed below are avoided, and the square plug can pass through the through holes 21 from the middle of the first sliding blocks 4a and the second sliding blocks 4b and can be smoothly inserted into the socket 1.

2) When circular plug inserts the circular port, be located 2 both sides second slider 4b atress on the support frame even, under the effect on plug and inclined plane, the second slider 4b of both sides drives first slider 4a common compression spring 3 and removes to support frame 2 centre to dodge the through-hole 21 that exposes the below, make circular plug pass through-hole 21 and realize inserting socket 1 smoothly.

When a single pole of a plug or a foreign object is inserted into one jack 11, only one end of the sliding module 4 at two ends of the support frame 2 is stressed, and the other end of the sliding module is not stressed. At the moment, the stressed end of the support frame 2 rotates to sink, namely, the end is like a seesaw, so that the sliding module 4 is difficult to be ejected; even if the foreign matter passes through the sliding module 4 which moves, the foreign matter is blocked again by the bottom plate of the support frame 2 due to the deflection of the through hole 21 and the insertion hole 11 on the support frame 2, and the plug or the foreign matter cannot contact with the inside of the socket 1 and the conductive member, thereby playing a role of preventing the abnormal insertion.

Example two

The overall structure of the present embodiment is similar to the present embodiment, and the differences are as follows: as shown in fig. 4, the insertion hole 11 of the two-hole sliding rail socket is a square hole. The slide module 4 is a single slide block. When the plug inserts socket 1 normally, the sliding blocks that are located 2 both sides of support frame are atress even, and under the effect of plug and inclined plane, the sliding block module compression spring 3 of both sides removes to support frame 2 centre to dodge the through-hole 21 of below, make the plug pass through-hole 21 and realize inserting socket 1 smoothly.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
