Electrical connector with anti-mismating mechanism for preventing incorrect insertion of a smaller sized mating connector

摘要

An electrical connector (100) for permitting insertion of a full sized plug and preventing insertion of a smaller sized plug includes an insulative housing (1) defining a receiving cavity (110) through a mating face (11) thereof for receiving a mating connector and a plurality of terminals (2) received in the housing. Each terminal defines a fixing portion (20) retained in the housing, a contacting portion (21) being inclinedly bent at an angle and extending into the receiving cavity from one end of the fixing portion and a soldering portion (22) extending from the other end of the fixing portion. The fixing portion further defines a supporting portion (23) with two ends connecting with the fixing portion, the supporting portion faces to and supports the contacting portion to prevent the contacting portion from further excursion.
