Technical Field

The utility model relates to an electric connector, concretely relates to plug-in binding post.

Background

In the plug-in type wiring terminal in the prior art, the buckling of the terminal pieces at two ends is realized by the mutual interference fit of the clamping points and the clamping point holes, specifically, the plastic clamping points are pressed into the plastic clamping point holes in a cold mode, and the clamping points and the clamping point holes are in interference fit. Wherein, the interference fit surface is a plane surface, achieving the buckling purpose. Problems and disadvantages of the prior art: when the product is assembled, the assembly position of the clamping point and the inner side edge of the body is in interference fit, and no guide is provided, so that the problem of difficult assembly exists; after the product is assembled, the binding force is smaller and the product risk is high because the matching surface of the clamping point and the hole is a plane and a plane.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: promote plug-in binding force of binding post.

In order to solve the technical problem, the utility model provides a following technical scheme: plug-in binding post's lock structure, including setting up the bayonet joint on the built-up member and setting up the jack on body spare, be equipped with the stuck point on the bayonet joint, set up the stuck point hole on the lateral wall of jack, the stuck point is equipped with first fitting surface, the stuck point hole be equipped with first fitting surface complex second fitting surface, first fitting surface and second fitting surface are the inclined plane.

The assembly part and the body part are connected through the matching of the plug connector and the jack, specifically, the plug connector is inserted into the jack, the plug connector and the jack are mutually extruded to generate elastic deformation, the plug connector to be inserted extends into the jack, the clamping point is buckled in the clamping point hole, the elastic potential energy is released, and the first matching surface is matched with the second matching surface. Drawing built-up piece and body spare, first fitting surface offsets with the second fitting surface, and the cohesion of built-up piece and body spare can effectively be improved in the inclined plane design, promotes and produces the property ability to promote the product quality.

Detailed Description

Referring to fig. 2 and 3, the snap-fit structure of the plug-in type connection terminal includes a plug 11 disposed on the assembly member 10 and a socket disposed on the body member 20, the plug is provided with a fastening point 12, a fastening point hole 22 is disposed on a side wall of the socket, the fastening point is provided with a first fitting surface 13, the fastening point hole is provided with a second fitting surface 23 fitted with the first fitting surface, and the first fitting surface and the second fitting surface are inclined surfaces.

The plug 11 and the fastening point 12 are provided with consecutive first guide surfaces 14, and the insertion hole is provided with second guide surfaces 24 capable of being matched with the first guide surfaces, as shown in fig. 2 and 4, the first guide surfaces and the second guide surfaces are inclined surfaces. The first guide surface 14 is formed by cutting the plug and the stuck point obliquely on an assumed plane, the first guide surface is located at the top of the plug, the second guide surface is located at the bottom of the jack, the plug is inserted into the jack, and the second guide surface is matched with the first guide surface to provide a condition for the plug to be smoothly inserted into the jack.

As shown in fig. 2, the bottom of the jack is provided with an abdicating structure 25 abdicating the plug-in connector 11, the top of the plug-in connector is inserted into the bottom of the jack and is matched with the abdicating structure, at this time, the fastening point 12 is aligned with the fastening point hole 22, and the fastening point is fastened into the fastening point hole. The abdicating structure can effectively prevent the plug-in connector 11 and the jack from loosening, and can also prevent the clamping point and the clamping point hole from loosening so as to improve the stability of the matching of the assembly part 10 and the body part 20.
