Description

Electrical connector with encapsulation injection molding material

【Technical field】

The utility model relates to a packaging technology for electric connector welding wires, and in particular to an electric connector structure in which each welding point is directly welded to a pre-formed wire packaging component.

【Background technique】

The method for encapsulating the electrical connector with hot melt adhesive is generally as follows: welding the electrical connector and the end of the wire. Apply ultraviolet glue (UV glue) to the connection between the welded electrical connector and the wire. The ultraviolet glue is hardened by a special light source to complete the assembly of the electrical connector sealing glue.

However, the cured product shape of the electric connector produced by the above assembly method is not easy to control, and the position positioning effect of the wire welding point is irregular, and the reliability is not good. It even causes the embarrassment that the welding point of the wire is exposed, and the electrical connector is short-circuited. Therefore, the above-mentioned assembling method has a limited protective effect on the positioning effect of the welding point of the wire and the short circuit that is easily pulled by an external force (pull force).

In view of this, in order to improve the above-mentioned shortcomings, the present inventor has produced the utility model through years of research and development of electrical connectors and the like.
