TWI778386B - 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 locking member, an ejecting member, and a first and second elastic members. The outer housing has a plurality of pushing bumps which are formed on an inner surface thereof. The ejecting member has a plurality of oblique surfaces. The pushing bumps contact the oblique surfaces, respectively. 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 pushing bumps to push the oblique surfaces, and then the ejecting member is protruded to push the mating connector outside, so as to perform a pre-ejection function.
