Electrical connector and method of making the same

Abstract

An electrical connector includes a terminal module and a main iron shell arranged outside the terminal module. The terminal module includes an insulating body and a plurality of conductive terminals held on the insulating body. The insulating body includes a base and extends forward from the base. The tongue plate, the main iron shell further includes a first iron shell and a second iron shell, the first iron shell includes a first cylinder portion formed with a receiving cavity and a first stop wall at the front end of the first cylinder portion and having a first opening , the second iron shell is fixed on the front end of the first blocking wall and forms a docking cavity communicating with the first opening, the base is accommodated in the receiving cavity, the front end of the base is pressed forward against the rear surface of the first blocking wall, and the tongue plate Through the first opening forward to protrude into the docking cavity, a better waterproof effect can be achieved.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector with a waterproof function that can be docked in a forward or reverse direction. 【Background technique】 [0002] Please refer to the Chinese Invention Patent No. CN104538781A published on April 22, 2015, which discloses a seamless shielding shell set outside the insulating body, and the inner surface of the shielding shell is a smooth surface, which is easy to fill the tail of the shielding shell to form a waterproof When the glue block is formed, the liquid glue before solidification may flow into the docking cavity at the front end of the shielding shell from the gap between the insulating body and the shielding shell, and the docking cavity at the front end of the shielding shell and the tail space do not form two relatively isolated parts. When the waterproof rubber block is aged and loosened, it is easy for external liquid to enter the electronic device fr...

[0002] Please refer to the Chinese Invention Patent No. CN104538781A published on April 22, 2015, which discloses a seamless shielding shell set outside the insulating body, and the inner surface of the shielding shell is a smooth surface, which is easy to fill the tail of the shielding shell to form a waterproof When the glue block is formed, the liquid glue before solidification may flow into the docking cavity at the front end of the shielding shell from the gap between the insulating body and the shielding shell, and the docking cavity at the front end of the shielding shell and the tail space do not form two relatively isolated parts. When the waterproof rubber block is aging and loose, it is easy for external liquid to enter the electronic device through the tail through the gap, and the waterproof effect is poor.

In the prior art, the shielding shell can be made of metal powder injection molding, and the inner wall of the shielding shell can be formed with a ring wall that abuts against the front end surface of the base of the insulating body backward, so that the docking cavity at the front end of the shielding shell and the space at the tail are formed. The two parts are relatively isolated, but the structure is more complicated and the manufacturing cost is higher
