Description

Universal Serial Bus Connector

The utility model relates to a universal serial bus connector.

Generally, the universal serial bus connector is provided with a terminal receiving seat, and a plurality of terminals are arranged on the terminal receiving seat, and the wires coated in the wire body are welded with each terminal on the terminal receiving seat to prevent electromagnetic interference The iron sheet covers the terminal accommodating seat, and the end of the metal shell connected with the clamping body is clamped on the wire body for fixing, and the plastic shell is glued to the metal shell by injection molding and The clamping body of the metal shell is mounted on, thereby forming a USB connector.

The manufacturing process of the above-mentioned Universal Serial Bus connector has various disadvantages: the joint shell formed by injection molding is rough and unsightly, and the circuit structure is easily damaged during injection molding, and the probability of defective products increases, increasing manufacturing cost. In addition, the use of high-precision and high-unit-price joint housings has a greater impact on manufacturing costs.

The purpose of the utility model is to provide a universal bus connector which is easy to assemble and has low manufacturing cost.

The universal serial bus connector of the utility model device includes a wire body, a terminal accommodating seat, a metal hollow shell and a plastic hollow shell, and is characterized in that: the wire body includes a protective layer and is coated The wires in the protective layer, the terminal accommodating seat is provided with several terminals, and the several terminals are electrically connected with the corresponding wires, and the metal hollow shell is sleeved and fixed on the terminal accommodating seat, And at least one buckle body is provided on the peripheral wall of the hollow casing; the plastic hollow casing is sleeved on the hollow casing, and on the peripheral wall of the hollow casing, at a position corresponding to the engaging hole, A buckle body is provided.

Due to the adoption of the above-mentioned technical solution, the universal serial bus connector of the present invention has a beautiful joint shell formed by mold forming, and the manufacture of the shell will not damage the circuit structure, resulting in a lower failure rate and lower manufacturing costs. In addition, by using high-precision, high-unit-price connector housings, the impact on manufacturing costs is reduced.

Below by preferred embodiment and accompanying drawing, the utility model universal serial bus connector is described in detail, in the accompanying drawing:
