Abstract

A plug connector includes a housing, a latch member and an actuating member. The housing includes a base portion and a tongue portion extending forwardly from the base portion. The tongue portion has a first surface and is sized to fit within the complementary connector. The base portion has a second surface disposed at a level on the housing that is above the first surface of the tongue portion. The latch member includes an engaging portion attached to the second surface of the base portion and a latching portion extending beyond the base portion and located above the first surface of the tongue portion. The actuating member has an operating portion extending beyond said base portion, a cooperating portion disposed between the latch member and said second surface of the base portion, and an intermediate portion interconnecting the operating portion and the cooperating portion. The actuating member is sized, structured and arranged such that movement of said actuating member away and toward said tongue portion caused the latching portion of the latch member to be raised and lowered relative to the first surface of the tongue portion. The intermediate portion of the actuating member has a portion being sized, structured and arranged such that movement of the actuating member away and toward said tongue portion causing the portion of the intermediate portion to be compressed by the base portion and to provide elastic restoring force to the latching member.
