Electrical connector and its terminal module assembly

Abstract

An electrical connector, which includes a terminal module assembly, a front insulator that is injection-molded to cover the terminal module assembly, and a rear insulator that is injection-molded at the rear of the front insulator. The terminal module assembly includes a pair of terminal modules and is attached to the The metal sheet outside the terminal module, each terminal module includes a conductive terminal and an insulating part carrying the conductive terminal, the front insulator is formed with a butt tongue plate, the butt tongue plate is provided with a butt surface, and the conductive terminal includes a contact part exposed to the butt surface , the rear insulator covers the rear of the front insulator to form a base, the base has a rear end surface, the metal sheet has a rear end surface and extends backward to the base, the insulating part is provided with a breaking surface parallel to the rear end surface of the base and The escape hole running through the broken surface backwards, the rear end surface of the metal sheet and the broken surface are both located in the base and not exposed on the rear end surface of the base. In the present invention, the rear end surface and the broken surface of the metal sheet are covered by the injection molding of the rear insulator, and the escape hole is filled at the same time, so as to improve the overall strength of the electrical connector.

Description

【Technical field】 [0001] The invention relates to an electrical connector and a terminal module assembly thereof, in particular to an electrical connector which avoids cracks and improves overall strength. 【Background technique】 [0002] Chinese utility model patent CN206004086U discloses an electrical connector combination, which includes a socket connector and a plug connector, the socket connector is provided with three docking cavities, and the plug connector is provided with three docking cavities. a butt tongue plate and a base, each butt tongue plate includes an upper and lower butt joint surface, two rows of conductive terminals respectively exposed on the upper and lower butt joint surfaces and a pair of shielding parts, the rear end surface of the shielding part is a distance from the rear end surface of the butt tongue plate The distance is so small that the rear end face of the metal part cannot be completely covered during injection molding, resulting in cracks....
