IPC: H01R13/639
Filed: 2019-07-12
Abstract: To mount a terminal in a power connector to a correct position in an insulating housing; to maintain mechanical strength of a lock assembly while improving the elasticity and flexibility thereof; and to reinforce the fixing of a male terminal of a clamping arm of the terminal and a rib portion of the insulating housing, ensuring good contact performance of the power connector.SOLUTION: An insulating housing 1 includes a terminal receiving groove 12 and a stopping wall. A terminal 3 is positioned in the terminal receiving groove and includes a mating portion, a stopping portion and a wire connecting portion. The stopping portion abuts against the stopping wall and includes first and second horizontal portions. The first and second horizontal portions include front end edges, respectively. Portions of front end portions are cut off, therefore when the terminal clamps a wire, the front end edges do not splay forward and outward to protrude forward, but are parallel to each other or respectively extend backwardly, which thus can avoid the first and second front end edges of the stopping portion from abutting against the stopping wall first due to the protruding.SELECTED DRAWING: Figure 7
