Abstract

A reversible dual-position electrical connector includes: an insulation seat provided with a base seat and a tongue; two rows of terminals, wherein the two rows of terminals are embedded into and plastic injection molded with the insulation seat, the terminal is integrally provided with, from front to rear, a connection portion, a contact, an extension and a pin, the contact is in flat surface contact with the tongue, elastically non-movable and exposed from two connection surfaces, and a bent segment is formed between the connection portion and the contact, so that the connection portion is lower than the two connection surfaces and embedded into the tongue; an inner insulating structure embedded and plastic injection molded with the insulation seat, wherein the contacts and the extensions of the two rows of terminals are in flat surface contact with and rest against the inner insulating structure.
