Electrical connector with an improved terminal base

摘要

An electrical connector includes a terminal base and plurality conductive contacts, and the conductive contacts defining a first group of contacts, and the first group of contacts including several signal contacts and several grounding contacts arranged with the signal contacts at intervals. The terminal base includes an insulative housing, and a conductive plastic block integrally molded with the insulative housing and combining with the insulative housing seamlessly, the conductive plastic block electrically contacts with the grounding contacts to electrically connect the grounding contacts together. Therefore, the seamless state prevents any loose from the conductive plastic block and the insulative one, which could make the terminal base to be steadier.

1. An electrical connector comprising:
a terminal base; a plurality of conductive contacts retained in the terminal base, the conductive contacts including a first group of contacts, and the first group of contacts including a set of signal contacts and a set of grounding contacts arranged with the signal contacts at intervals; wherein the terminal base includes an insulative housing, and a conductive plastic block integrally molded with the insulative housing and combining with the insulative housing seamlessly, the conductive plastic block electrically contacts with the grounding contacts to electrically connect the grounding contacts together; wherein the insulative housing includes a main portion and a tongue plate extending forwardly from the main portion, and each of the first group of contacts include a contact portion located in the tongue plate, a retaining portion retained in the main portion and a soldering tail extending through a rear surface of the main portion, wherein the conductive plastic block is set in the main portion and abuts against the retaining portions of the all grounding contacts; wherein the tongue plate defines a plurality of slots, and the slots pass backwards through the rear surface of the main portion, wherein the main portion defines a groove communicating with the slots and corresponding to the retaining portions of the signal contacts, and the conductive plastic block defines several protruding portions protruding into the groove and electrically and mechanically abutting against the retaining portions of the grounding contacts.
