SUMMERY OF THE UTILITY MODEL

The utility model aims at having the above-mentioned problem to current technique, provided a locking structure of socket, the utility model aims to solve the technical problem that: how to keep the plug inserted in the plug bush tight.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides an anti loosening structure of socket, socket include the base and inlay the plug bush of establishing on the base, the jack has on the base, the clamping part in the embedding jack has on the plug bush, supply plug male socket has on the clamping part, anti loosening structure is including setting up the buffer hole on the base, be formed with between buffer hole and the jack and block the body, the clamping part struts the back can with block the body and offset and lean on.

The plug is inserted into the jack, the clamping part of the plug bush is expanded by the plug, the clamping part is abutted against the blocking body after being expanded, the blocking body is formed between the buffer hole and the jack, the blocking body is known to be a part of the base, the existing base is usually made of plastic materials and has certain elasticity, so the blocking body also has certain elasticity, under the action of the elastic force of the blocking body, the blocking body has an acting force inwards acting on the plug bush, thereby the clamping force of the clamping part on the plug is increased, the looseness generated when the clamping part clamps the plug is avoided, the plug is inserted into the plug bush and is kept fastened, the loose phenomenon of the plug bush and the plug caused by poor contact of the plug bush and the plug is prevented, the buffer hole is arranged on the base and is used for providing a buffer space for the blocking body when the blocking body is contacted with the clamping part of the plug bush, and the extrusion stress of the clamping part and the plug bush can be effectively relieved, the fatigue deformation of the clamping part is relieved, so that the elastic restoring force of the clamping part is reduced, and the plug is inserted into the plug bush and always kept fastened.

In the anti-loose structure of the socket, the buffer hole is long and the length of the buffer hole is not less than that of the jack. The long-strip-shaped buffer hole enables the buffer length to be long, the clamping part and the blocking body are guaranteed to be abutted against each other, the clamping part can be wholly and evenly provided with elastic force by the blocking body, the clamping part is enabled to be large in acting force for inwards squeezing the plug, the clamping force of the two clamping parts on the plug is increased, and the plug is inserted into the plug bush to be kept fastened.

In the anti-loose structure of the socket, the width of the buffer hole is smaller than that of the jack. The buffer hole is reasonable in structure, and the buffer space is provided for the blocking body, and meanwhile, the structure can be kept compact.

In the anti-loose structure of the socket, the blocking body is in a strip shape. The blocking body in the strip shape ensures that one side of the clamping part is completely abutted against the clamping part, so that the acting force of the blocking body acting on the clamping part is large, the clamping force of the clamping part on the plug is larger, and the clamping part clamps the plug more tightly.

In the anti-loosening structure of the socket, the number of the buffer holes is two, the two buffer holes are located on two sides of the jack, the blocking bodies are formed between each buffer hole and the jack, and the clamping part is located between the two blocking bodies. All be provided with the body that blocks in the both sides of jack, when the plug inserts in the jack, the both sides homoenergetic that make the clamping part of plug bush leans on with blocking the body counterbalance, make the both sides of clamping part all have an inside effort to the plug bush, make the both sides of clamping part press from both sides the plug simultaneously, make the clamping part can fasten the plug centre gripping more, prevent that the plug from appearing not hard up on the socket and arousing plug bush and plug contact failure, two buffer holes are two respectively and block the body and provide buffer space.

In the anti-loose structure of the socket, the clamping part comprises two clamping pieces which are arranged oppositely, and the socket is formed between the two clamping pieces. When the plug inserts in the jack, one of them centre gripping piece supports with blockking the body and supports and lean on, and another supports with the jack inner wall and supports and lean on, can realize the centre gripping to the plug through two centre gripping pieces, and the centre gripping piece is deformed more easily and is carried out the centre gripping to the plug, makes the plug insert and keeps the fastening on the plug bush.

Compared with the prior art, the anti-loosening structure of the socket has the following advantages:

a blocking body is formed between the buffer hole and the jack, and under the action of elastic force of the blocking body, the clamping portion has inward acting force on the plug bush, so that clamping force of the clamping portion on the plug is increased, looseness is avoided when the plug is clamped by the clamping portion, the plug is inserted into the plug bush to be kept fastened, and the plug is prevented from being loose on the socket to cause poor contact of the plug bush and the plug.
