Abstract

The utility model relates to a folder locked connector, which consists of a connector body, lock plates symmetrically manufactured on two sides of the connector, and folders manufactured on the upper side and the lower side of the connector. Evenly distributed wire guide holes are integrally manufactured in the middle of the connector body, the folders are integrally connected with the connector body through bending point portions, the section of each bending point portion of the folders is of a structure with two thick ends and thin middle, and the outer end face of the bending point portion is level to the outer end face of the connector body. The bending point portions of the folders on two sides of the connector are manufactured into the forms with two thick ends and thin middle, thereby preventing stress concentration generated at bending points from causing peeling or breakage at the bending points when the folders are folded, increasing service life of the folders on two sides of the connector, and accordingly increasing service life of the connector.

Description

Folding locking-type connector

Technical field

The utility model belongs to electric field, especially a kind of folding locking-type connector.

Background technology

It is connectors of plug-in that the connector that integrated circuit adopted has many, and this connector also needs the folding of both sides that electric wire is clamped the location when plug-in mounting.Plug-in connector frequency of utilization when the plug circuit is more, and therefore, folding is as the execution position of plug, and its quality and structure level are crucial.Find when detecting fatigue life, when double spread repeatedly fastens under different experimental enviroment conditions,, folding is ruptured at bending point position easily, thereby cause connector to be scrapped in the bigger stress concentration phenomenon of bending point position generation by folding.

By retrieval, do not find the technical literature that addresses the above problem as yet.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of folding locking-type connector that can prevent effectively that folding bending point position stress from concentrating is provided.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of folding locking-type connector, constitute by connector body, made pintle hook lock and the made folding of the upper and lower symmetry of connector of connector bilateral symmetry, the uniform through wires hole of connector body middle part for being made into integration, folding is connected with the connector body one by the flex point position, it is characterized in that: the cross section at the bending point position of described folding is that two is thick, the structure of intermediate thin, and its outer face flushes with the outer face of connector body.

And the made two structure thick, intermediate thin in the cross section at the bending point position of described folding is a grading structure.

The beneficial effects of the utility model are:

1, the bending point position of the both sides folding of this connector makes that two is thick, the form of intermediate thin, when having avoided folding to fasten in bending point problem of stress concentration that the position produces, improved the useful life of the both sides folding of connector, and then the useful life of having improved connector.

2, the structure of this connector has been avoided the peeling or the breakage problem of folding, can guarantee the abundant fastening of the main part and the folding part of all similar products, has improved the quality level of connector.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.

A kind of folding locking-type connector, constitute by connector body 3, made pintle hook lock 4 and the made folding 1 of the upper and lower symmetry of connector of connector bilateral symmetry, the uniform through wires hole of connector body middle part for being made into integration, folding is connected with the connector body one by bending point position 5, and contiguous bending point position is shaped on line ball fin 2 in folding.

Innovative point of the present utility model is:

The cross section at the bending point position of folding makes that two is thick, the structure of intermediate thin, and its outer face flushes with the outer face of connector body.

Made two, the cross section at the bending point position of folding is thick, the structure of intermediate thin, and " approach " is grading structure with " thick " of both sides in the middle of it, with the problem of stress concentration of minimizing bending point.

Claims
