Abstract

An electrical connector includes: a terminal element; a grounding element; an insulating housing; a metal shell enclosing the insulating housing; and two solder terminals extended outward from the metal shell. Wherein the grounding element has at least a supporting rib which is utilized to enhance the structure strength of the grounding element so as to ensure a good grounding effect in limited space. Besides, every one of those solder terminals of the metal shell has a winding portion bended in a tilting angle. Additionally, the metal shell further includes a partner-fitting portion, and two short sides of the peripheral thereof bended backward to form a chamfer-type guiding portion so as to make a corresponding connector connect to the electrical connector smoothly.

Claims
