## Abstract

The present disclosure relates to a power connector which comprises an insulative housing and a terminal. The insulative housing defines a terminal receiving groove therein and comprises a stopping wall. The terminal is positioned in the terminal receiving groove and comprises a mating portion, a stopping portion and a wire connecting portion. The stopping portion abuts against the stopping wall and comprises a first horizontal portion and a second horizontal portion. The first horizontal portion comprises a first front end edge. The second horizontal portion comprises a second front end edge. A portion of a front end of the first horizontal portion and a portion of a front end of the second horizontal portion are cut off, therefore when the terminal clamps the wire, the first front end edge and the second front end edge do not splay forwardly and outwardly to protrude forwardly, but are parallel to each other or respectively extend backwardly, which thus can avoid the first front end edge and the second front end edge of the stopping portion from abutting against the stopping wall first due to the protruding.

## Claims

### Claim 1

A power connector, comprising:
an insulative housing;
a lock assembly provided to an upper surface of the insulative housing and positioned in an up-down direction with the insulative housing, the lock assembly comprising:
a frame defining an opening therein, the frame comprising:
a front bracket;
a rear bracket facing the front bracket and spaced apart from the front bracket by the opening, and the front bracket and the rear bracket being positioned in a front-rear direction;
a first side bracket extending in the front-rear direction and connecting the front bracket and the rear bracket; and
a second side bracket facing the first side bracket, spaced apart from the first side bracket by the opening and connecting the front bracket and the rear bracket, the first side bracket and the second side bracket being positioned in a left-right direction, the opening being formed by the front bracket, the rear bracket, the first side bracket, and the second side bracket; and
a first leg positioned between the front bracket and the rear bracket of the frame and extending from the first side bracket of the frame to the insulative housing in the up-down direction and connecting with the insulative housing;
a second leg positioned between the front bracket and the rear bracket of the frame and extending from the second side bracket of the frame to the insulative housing in the up-down direction and connecting with the insulative housing;
a first elastic arm extending outwardly from a first end of the rear bracket of the frame in the left-right direction, and then extending toward the front bracket of the frame in the front-rear direction, and then extending in the up-down direction to the insulative housing and connecting with the insulative housing; and
a second elastic arm extending outwardly from a second end of the rear bracket of the frame in the left-right direction, and then extending toward the front bracket of the frame in the front-rear direction, and then extending in the up-down direction to the insulative housing and connecting with the insulative housing.

### Claim 2 (depends on 6)

The power connector according to claim 6, wherein the insulative housing is correspondingly assembled with an external insulative housing of an external power connector in the front-rear direction, a protruding block is provided to an outer surface of the external insulative housing and latched with the opening of the lock assembly of the insulative housing.

### Claim 3 (depends on 6)

The power connector according to claim 6, wherein the insulative housing further comprises two side walls positioned in the left-right direction, two latching blocks positioned in the up-down direction are provided to each of the two side walls, a guiding rib extending the front-rear direction is provided between the two latching blocks of each of the two side walls.

### Claim 4 (depends on 6)

The power connector according to claim 6, wherein the front bracket, the rear bracket, the first side bracket, and the second side bracket of the frame are thin cylinders and sizes thereof can avoid a sink mark deformation due to an uneven wall thickness of a mold injection in manufacturing of the frame.

### Claim 5

A power connector, comprising:
an insulative housing defining a terminal receiving groove therein, the insulative housing comprising:
a rib portion protruding from the insulative housing into the terminal receiving groove; and
a terminal positioned in the terminal receiving groove of the insulative housing, the terminal comprising:
a mating portion;
a clamping portion connecting with the mating portion, the clamping portion comprising:
a first side wall;
a second side wall facing the first side wall, the first side wall and the second side wall being positioned in a left-right direction;
a first clamping arm having two first end portions and a first middle portion positioned between the two first end portions, the two first end portions being respectively connected with the first side wall, the first middle portion protruding toward the second side wall; and
a second clamping arm having two second end portions and a second middle portion positioned between the two second end portions, the two second end portions being respectively connected with the second side wall, the second middle portion protruding toward the first side wall;
the first middle portion of the first clamping arm and the second middle portion of the second clamping arm clamping and being fixed to the rib portion of the insulative housing; and
a wire connecting portion connecting with the clamping portion.

### Claim 6 (depends on 5)

The power connector according to claim 5, wherein the insulative housing further comprises two side walls positioned in the left-right direction, a stopping block extending into the terminal receiving groove is provided to each of the two side walls, the stopping blocks of the two side walls support the terminal.
