Description

Anti-return structure of connector

Technical Field

The utility model relates to the technical field of connector connection, in particular to a connector anti-return structure.

Background

In the prior art, when the puncture connector is plugged with the circuit board, the puncture connector is usually limited and fixed, so that the puncture connector is prevented from loosening and shaking. At present, the limiting connection mode generally adopted is to puncture the connector and add a plastic part limiting rib, and the structural mode has high fault tolerance, but after the plastic part is deformed, the connector is easily damaged by propping or the position of the circuit board is easily deviated. Some puncture connector bodies carry out clamping with the circuit board from taking the buckle, and the assembly is comparatively convenient, but this kind of condition can't judge whether the connector joint is put in place, therefore has the risk of returning to the position.

Disclosure of Invention

The utility model aims to solve the technical problems of overcoming the defects of the prior art and providing the connector anti-withdrawal structure which has the advantages of visual structure, high safety performance and firmness and stability after being inserted.

In order to solve the technical problems, the technical scheme of the utility model is as follows:

the utility model provides a connector prevents returning position structure, it includes circuit board and connector, the grafting groove has been seted up to circuit board edge, elastic deformation groove has all been seted up to grafting groove both sides, it has two buckle spare to take shape between the elastic deformation groove of grafting groove and both sides, the connector cartridge carries out spacing firm in the grafting inslot and through the buckle spare of both sides.

Furthermore, the outer end part of the buckle piece is also provided with a limiting step, and the connector can form limiting through the limiting step when being inserted into the inserting groove.

Further, the included angle between the limiting step and the clamping piece is 90 degrees.

Further, the end part of the limit step is also provided with a guide cambered surface.

By adopting the technical scheme, the utility model has the following beneficial effects:

1. according to the utility model, the circuit board is provided with the inserting grooves and the elastic deformation grooves, the buckle is formed to clamp the inserting piece, and the buckle structure is designed on the circuit board, so that the visual characteristic is realized, and whether the connector is clamped in place can be directly judged, so that the connector is quick and convenient.

2. According to the utility model, the plug connector is inserted through the insertion groove, and the elastic deformation grooves are formed in the two sides of the insertion groove, so that the buckles on the two sides can deform into the elastic deformation grooves when the plug connector is inserted, the buckles can restore to the original position after being completely inserted into place, and no excessive acting force is applied to the circuit board after being inserted into place, so that the situation that the plug connector is damaged by propping up can be avoided, the position of the circuit board is prevented from being deviated, and the safety performance is improved.

3. The limiting steps are further designed and formed at the end parts of the buckles at the two sides, so that the effect of limiting and stabilizing can be achieved after the plug connector is completely clamped in place, and the plug connector is effectively prevented from backing. Meanwhile, due to the design of the guide cambered surface on the limiting step, the plug connector can be easily installed in the plug groove and smoothly detached, and the edge of the plug connector can be protected from being pressed and damaged.

Detailed Description

In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

As shown in fig. 1 to 5, in the present embodiment, a connector anti-withdrawal structure is provided, which is mainly composed of a circuit board 1 and a connector 2. In order to install the connector 2, the edge of the circuit board 1 is provided with an adaptive inserting groove 3, and meanwhile, the edges of the circuit board 1 at two sides of the inserting groove 3 are provided with elastic deformation grooves 4, so that two buckling pieces 5 are formed between the inserting groove 3 and the elastic deformation grooves 4 at two sides, and the connector 2 can be inserted in the inserting groove 3 and is limited and stable through the buckling pieces 5 at two sides. The circuit board 1 is provided with the inserting groove 3 and the elastic deformation groove 4, and the clamping piece 5 is formed to clamp the inserting piece 2, so that the circuit board has the visual characteristic, and whether the inserting piece 2 is clamped in place can be directly judged, so that the circuit board is quick and convenient. In addition, because the buckle parts 5 on two sides can deform into the elastic deformation grooves 4 when the plug connector 2 is inserted, the buckle parts 5 can be restored to the original positions after the plug connector 2 is completely clamped in place, and no redundant acting force is applied to the circuit board 1 after the plug connector 2 is inserted in place, the plug connector 2 can be prevented from being damaged by propping up, and the position of the circuit board 1 is prevented from being deviated.

In order to form a more stable inserting effect for the connector 2, the outer end part of the clamping piece 5 in the embodiment is further provided with a limiting step 6, and an included angle between the limiting step 6 and the clamping piece 5 is 90 degrees, so that when the connector 2 is completely clamped into the inserting groove 3, the limiting step 6 can be used for tightly limiting the edge of the connector 2, thus not only playing the limiting and stable effects, but also effectively preventing the connector from retreating.

In addition, in order to assist the insertion of the plug connector 2, a guiding cambered surface 7 is formed at the end part of the limiting step 6, so that the plug connector 2 can be easily and smoothly assembled or disassembled when being disassembled, and the edge of the plug connector 2 can be protected from compression damage.
