Electric connector assembly

Abstract

The invention discloses an electric connector assembly comprising a circuit board which comprises a first surface, a second surface and a plurality of first through holes which are communicated with the first surface and the second surface; an electric connector which comprises an insulating body located on the first surface and a plurality of conductive terminals arranged on the insulating body, wherein each conductive terminal is provided with a conductive connection part, the conductive connection parts penetrate through the first surface to enter the corresponding first through holes. The electric connector further comprises a shielding shell for accommodating the insulating body; a shielding piece, located on a second surface for shielding the plurality of conductive connection parts and being electrically isolated from the conductive connection parts. The shielding piece and the shielding shell are electrically connected with each other to form grounding; the shielding piece located on the second surface of the circuit board shields the plurality of conductive connection parts of the plurality of conductive terminals and prevents the conductive connection parts from leaking electromagnetic interference, and the shielding piece and the shielding shell are electrically connected with each other and grounded, so that the shielding piece and the shielding shell can jointly form relatively complete electromagnetic shielding for the conductive terminals.

[0004] The existing electrical connector assembly includes a substrate and an electrical connector arranged on the substrate. The electrical connector includes an insulating body, a plurality of terminals disposed in the insulating body, and a metal shell for receiving the insulating body to provide electromagnetic shielding. , where the pins of the terminals are DIP pins, that is, the pins of the terminals pass through the substrate to form an electrical connection, so the metal shell must not completely surround the terminals, that is, a part of the terminals must be exposed outside the metal shell

With the development of technology, due to the increasingly high frequency of signals transmitted by terminals and the compact arrangement of various electrical components brought about by the miniaturization of equipment, the electromagnetic interference leaked by terminal pins can no longer be ignored. It will have adverse effects on the entire electrical system in which the electrical connector assembly is applied
