Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection, in particular to an electric connector. Background Art

[0002] As an electrical connection component, electrical connectors are widely used in the fields of circuit boards, circuit plugging, etc. Most of the existing electrical connectors include a shell, an insulating gel, a terminal group and a middle clip. The terminal group is installed in the insulating gel, and the middle clip is installed in the insulating gel and located at the front end of the terminal group. Hooks are provided at both ends, and the shell is fixed on the outside of the insulating gel. Although this type of electrical connector can meet the use needs to a certain extent, its disadvantage is that the middle clip is separated from the terminal, which is easy to move during the injection molding of the insulating gel, affecting the stability of the overall structure.

[0006] Preferably, the inner side of the hook is parallel to the terminal located at the outermost side of the terminal group, and the width of the hook gradually increases.

[0007] Preferably, the front end and the rear end of the hook both have an arc-shaped transition.

[0008] Preferably, the connecting piece is integrally formed with the two outermost terminals of the terminal group.

[0009] Preferably, the terminal group and the insulating colloid are integrally injection molded.

[0010] Preferably, rear ends of the plurality of terminals are distributed at equal distances on the rear end of the insulating colloid.

[0011] Preferably, the top and bottom of the insulating colloid are provided with grooves, and the interior of the shell is provided with bumps, and the bumps are embedded in the grooves to fix the shell on the outside of the insulating colloid.

[0012] Compared with the prior art, the beneficial effect of the utility model is that the utility model connects the connecting piece to the negative terminals on the two outer sides of the terminal group, which can not only increase the current load of the negative terminal, but also make the structure of the two negative terminals relatively stable. Hooks extend from both ends of the connecting piece to avoid the traditional middle clip structure, so that the terminal group and the insulating colloid are positioned more accurately during injection molding, the overall structure is more solid, and the production efficiency is effectively improved.
