Description

The USB connector male

Technical field

The utility model relates to a kind of connector parts, relates in particular to a kind of USB connector male.

Background technology

The USB connector male of prior art, the outside is made up of containment vessel and plastic cement shell.Between this connector male head and the female seat is that simple plug-in cooperates, and does not have lock function, and male is easy to extract from female seat.This connected mode lacks fastness and stability.

The utility model content

The purpose of this utility model is for overcoming the deficiencies in the prior art, a kind of USB connector male of the LOCK of having function is provided, and is stuck in the female seat dual-side groove and can not extracts after inserting it into female seat, by button shell fragment inside compression in the left and right sides can be extracted.

For achieving the above object, the utility model has adopted following technical scheme:

A kind of USB connector male comprises plastic cement shell and containment vessel, and the rear end of containment vessel is placed in the plastic cement shell, and the both sides of plastic cement shell are respectively equipped with the through hole that can insert button near the position of containment vessel; Two sides of containment vessel also are respectively equipped with through hole, are provided with groove by through hole to the side of plastic cement shell; Two shell fragments that front end is provided with the snap close projection are installed in the plastic cement shell, fixedly connected with the plastic cement shell in its rear end, and front end snap close projection passes from the through hole of containment vessel; The both sides button is located in two side through hole of plastic cement shell, and its inner props up shell fragment, pin or release button may command shell fragment projection in the turnover of containment vessel two side through hole.

Described containment vessel two sides are respectively equipped with groove, and the front end of shell fragment extends to through hole along groove, and the snap close projection of shell fragment front end passes from through hole.

Button the inner of described shell fragment is provided with T type groove, and shell fragment passes from T type groove.

Owing to adopted said structure, after the USB connector male is inserted female seat, be stuck in the female seat dual-side groove and can not extract, by button shell fragment inside compression in the left and right sides can be extracted, strengthened connector connection stability and fastness.
