Description

Electrical connector metal shell structure

technical field

The utility model relates to a metal shell structure of an electric connector, in particular, the opening end is made by drawing and forming, so that the opening end does not have any connection gap, and the structural strength of the opening end is greatly improved.

Background technique

Electrical connectors have become an indispensable component in various electronic product devices. Among them, common electrical connectors such as USB connectors used to connect hosts with keyboards and mice, and newly introduced HDMI connectors in recent years.

These electrical connectors usually have a common feature, that is, their exposed sockets are formed by a metal shell made of a hollow frame to accommodate the mating plug and provide good shielding and grounding effects to ensure the signal between the two. The transmission is reliable.

At present, most of the metal shells used in this type of electrical connectors are made of flat plates that are bent several times and then the free edges on both sides of the plates are fastened together to form a polygonal open metal shell. The metal shells of most USB-type connectors are made in this way. However, this method only relies on the thickness of the metal sheets to interlock each other. When there is a slight warping deformation or position shift between the edges on both sides, the two may become loose and the metal shell will lose its opening shape.

In addition, since the existing structure will produce a seam at the opening after being joined, the strength of the overall structure is weak, which causes inconvenience in use, which is a pity.

It can be seen that the above-mentioned existing metal shell of the electrical connector still has many shortcomings, which is not a good design and needs to be improved urgently.

In view of the above-mentioned shortcomings derived from the metal shell of the existing electrical connector, the inventor is eager to improve and innovate, and after years of painstaking research, he finally successfully developed and completed the structure of the metal shell of the electrical connector.

Another object of the present utility model is to extend the wired end structure behind the open end, the wired end structure includes an upper cover and a lower cover of the wired end, and the upper cover and the lower cover are fixed to each other through the buckle block and the buckle hole. The open end can accommodate the electrical connector, and the wire end can accommodate the wire body connected with the electrical connector.

In order to achieve the above purpose, the housing structure of the electrical connector of the present invention includes an open end, which is formed by the top wall, the bottom wall and the two side walls connecting the top wall and the bottom wall, so that it forms an accommodating space, The above-mentioned open end is made by drawing and forming, and there is no joint between the top wall, the bottom wall and the side wall; the line end is connected to the rear of the open end, and the line end includes an upper cover and a lower cover, an upper cover and a lower cover. Clamping parts respectively extend from the rear of the lower cover, and the two clamping parts can be fastened with each other to clamp and fix the wire body. In one embodiment, the open end is shaped as a rectangular window for the USB connector.

In one embodiment, a hole is provided on a wall of the opening end, so that it can be used for docking with the docking connector.

In one embodiment, the wire end is integrally formed and extends behind the open end.

In one embodiment, the wire end and the open end can be separated, and the wire end and the open end are connected and fixed through the connection block and the connection hole structure.

In one embodiment, the upper cover is formed with a cover surface that is coplanar with the top wall, and the lower cover is formed with a cover surface that is coplanar with the bottom wall, and both sides of the cover surface are bent to form a U. font structure.

In one embodiment, the clamping portion is slightly arc-shaped, so that the two clamping portions can clamp and fix the wire body.

In one embodiment, buckle blocks and buckle holes are respectively provided on the side surfaces, and the upper cover and the lower cover are locked and fixed to each other by means of the buckle blocks and the buckle holes after being closed.

In one embodiment, the two side walls of the opening respectively form an inwardly bent connecting wall.

The utility model is different from the existing structure and its beneficial technical effect is that the existing electric connector housing is integrally formed first and then made by bending, so the front opening naturally produces some connection gaps, making the overall strength lower , In addition, the open end of the existing electrical connector housing and the wire end are not completely integrally formed, so the wire end needs to be assembled after manufacture, which greatly increases the cost of manufacturing and assembly; on the other hand, the open end of the utility model is It is made by drawing and forming, so that there is no seam between the open ends, which increases the strength of the open end; and the wire end and the open end are integrally formed to reduce manufacturing and assembly costs.
