I/O connector with lock-release mechanism

摘要

A connector ( 100 ) includes a cover defining a receiving space for receiving a terminal module ( 3 ). A notch ( 15 ) is defined through a side wall of the cover. A concaved stop portion ( 151 ) is defined in the side wall of the cover and communicating with the notch. The terminal module has a number of terminals ( 33 ) held therein and includes a forwardly projecting mating portion ( 32 ) beyond the cover. A lock member ( 34 ) is received in the housing for mating with a mating connector. A lock-release button ( 24 ) is received in the notch for urging the lock member into a release position and includes a fixing end fixed to the cover and a free operating base ( 240 ) swinging about the fixing end. A stop plate ( 241 ) projects from the free operating base to engage with the stop portion of the cover for preventing the lock-release button disengaging the notch.
