Interference-proof electrical plug connector

摘要

An interference-proof electrical plug connector has an insulative housing, two terminal sets, a shielding-grounding plate and a shell. The terminal sets are mounted in the insulative housing and each terminal sets has multiple conductive terminals. Each terminal set has multiple conductive terminals and at least one pair of super-speed signal terminals. Each super-speed signal terminal has a mounting section including a widening tab laterally protruding from the mounting section toward an adjacent super-speed signal terminal to reduce the distance between the super-speed signal terminals of the pair. The shielding-grounding plate is mounted in a rear end of the insulative housing. The widening tabs of each pair of the super-speed signal terminals effectively diminish impedance of the super-speed signal terminal such that input loss and return loss of the super-speed signal terminals are reduced.

1. An interference-proof electrical plug connector comprising:
an insulative housing having a top board, a bottom board, two opposite sidewalls and an insertion space defined in a front end of the insulative housing among the top board, the bottom board and the sidewalls; two terminal sets being substantially point symmetrical to each other according to a centre of symmetry of the insertion space, and mounted respectively on an upper inner surface of the top board and a lower inner surface of the bottom board, wherein each terminal set has
multiple conductive terminals, each conductive terminal having
a mounting section mounted on the top board or the bottom board of the insulative housing;an electrical contacting section formed on and protruding forward from the mounting section and extending in the insertion space; anda soldering section formed on and protruding backward from the mounting section; andat least one pair of super-speed signal terminals, the super-speed signal terminals of each pair located adjacent to each other, andeach super-speed signal terminal having
a mounting section mounted on the top board or the bottom board of the insulative housing and having a widening tab formed on and protruding from the mounting section, wherein the widening tabs of the super-speed signal terminals of each pair extend toward each other such that a distance between the mounting sections of the super-speed signal terminals of each pair is less than that between the mounting sections of adjacent conductive terminals or that between the mounting sections of adjacent super-speed signal terminal and conductive terminal;an electrical contacting section formed on and protruding forward from the mounting section and extending in the insertion space; anda soldering section formed on and protruding backward from the mounting section; a shielding-grounding plate mounted in a rear end of the insulative housing and having
a shielding body mounted in the rear end of the insulative housing and located between the terminal sets; andtwo resilient hooking arms formed on and protruding forward respectively from two opposite sides of the shielding body and extending in the insertion space of the insulative housing; and a shell having a cavity defined in the shell and accommodating the insulative housing; wherein two central conductive terminals are removed from one of the terminal sets and the conductive terminals of one of the terminal sets are fewer than the conductive terminals of the other terminal set.
