TWI767299B - Connector with direct-lock and rotating pre-ejection function - Google Patents

Abstract

A connector with direct-lock and rotating pre-ejection function includes an insulated body, a plurality of terminals, an inner housing, an outer housing, a fixing ring, a locking member, an ejecting member, and a first and second elastic members. The outer housing has a cam surface formed therein. The ejecting member has a collision portion, and the collision portion contacts the cam surface. When the connector is plugged to a mating connector, a buckling body of the locking member is able to mutually latch a locking body of the mating connector so as to achieve a direct-lock function. When the connector is separating from the mating connector, the outer housing is rotated in a clockwise or counterclockwise direction, so that the buckling body of the locking member and the locking body of the mating connector can be separated away to achieve a unlocking function. In addition, the outer housing can drive the cam surface to push the collision portion, and then the ejecting member protrudes to push the mating connector outside, so as to perform a pre-ejection function.
