Abstract
Abstract An electrical connector ( 100 ) for receiving a mating plug ( 200 ) having a number of plug contacts and a metal shell. The electrical connector has an insulative housing ( 10 ) provided with a base portion ( 13 ) and a tongue portion ( 14, 15 ) extending forwardly from the base portion. A set of first electrical contacts ( 21 ) and a set of second electrical contacts ( 22 ) are arranged in the isulative housing for engaging with the plug at a front and a rear position respectively. Each contact ( 21, 22 ) includes a contact section ( 214, 222 ) electrical connected with the contacts of the plug. An insulator ( 40 ) is located in front of the first electrical contacts for avoiding an improper connection between the contacts and the plug.
