Publication number: 20130164977Abstract: An electrical connector includes an insulating housing, a plurality of terminals assembled in the insulating housing, and a shielding shell curved from a metal plate to show a hollow barrel shape and enclose the insulating housing. An inserting space is formed between a front of the insulating housing and periphery inner sides of a front of the shielding shell, and has a free open front end for inserting a mating connector therefrom into the inserting space. The terminals project into the inserting space to connect with the mating connector. A pair of elastic fool-proofing elements is formed at two opposite bottom corners of the open front end of the shielding shell and each shows an arc shape from a front view. Two cambered faces of the elastic fool-proofing elements face each other for guiding the insertion of the mating connector and further elastically resisting against the mating connector.Type: ApplicationFiled: December 21, 2011Publication date: June 27, 2013Inventors: Guang-Li Huang, Li-Jun Xu, Ming-Han Lin
