Therefore, the metal casing itself is bound to have a seam, which makes it easy for dust and water to pass through the seam. Infiltration, in other words, the existing metal casing itself does not have the effect of dustproof and water repellent.

Moreover, the existing metal casing only wraps around the insulative body, and at most, some snap structures are added. Therefore, the structural strength between the metal casing and the insulative body is insufficient, and the plugging or using is repeated after a long period of time. Factors such as incorrect plug-in angle will cause the metal shell to be twisted, deformed or displaced relative to the insulating body, resulting in a gap between the trailing edge of the metal shell and the insulating body, in the event of water and liquid splashing. At this time, the water liquid will penetrate through the gaps, in other words, between the trailing edge of the existing metal casing and the insulating body, the water repellent effect is easily lost due to distortion, deformation or displacement.

Therefore, how to design a novel that can improve the above-mentioned defects is a major issue that the creators of this case want to solve.

The purpose of this creation is to provide an electrical connector having a dustproof and water repellent function.

In order to achieve the above object, the present invention provides an electrical connector having a dustproof and water repellent function, comprising: an insulative housing having a plurality of protrusions, the assembly being provided with a plurality of protrusions; and a plurality of terminals disposed on the insulative body And a metal inner casing that is drawn by drawing, wrapped around the insulating body and having a plurality of connecting ports and a trailing edge formed corresponding to the grouping port, the grouping port corresponding to the group of the connecting portion Then, the plurality of protrusions abut against the inner surface of the metal inner casing to position the metal inner casing to the assembly portion, and the rear edge abuts against the insulation body.

Compared with the prior art, the present invention has the following effects: even after repeated insertion and removal or incorrect user insertion angle, the rear edge of the metal inner casing can be firmly abutted against the insulating body without gaps. And the metal inner shell has no seams, so it has a complete dustproof and water repellent effect.
