Electrical connector having flexibly and steadily engagement between metallic shells and grounding terminals

摘要

An electrical connector (100) includes an insulating housing having a pair of longitudinal side walls (11) and a pair of end walls (12) connecting the side walls thereby defining a receiving cavity therebetween. A plurality of terminal grooves (13) are defined in an inner side of the side wall and exposed to the receiving cavity. A plurality of terminals are received in said terminal grooves and comprise signal terminals and grounding terminals. At least one shell (3) covers on an outer side of the side wall and defines an upper side and a lower side. At least one grounding arm (33) is formed at the lower side of the shell and spaced to the lower side of the shell thereby forming a slot (333) therebetween. The at least one grounding arm (33) has a first portion (331) abutting against the side wall and a second portion (332) mechanically and electrically contacting with the grounding terminal.
