The two opposite inner walls of the housing are respectively provided with first grooves, and the two opposite outer walls of the cylinder are respectively provided with second grooves. The first terminals are respectively Correspondingly combined in the first groove, each first terminal includes a first clamping piece arranged parallel to the inner wall and a first contact piece that shrinks from the front side of the first clamping piece and extends forward, and the second terminals correspond to Combining in the second groove, each second terminal includes a second clamping piece parallel to the outer wall and a second contact piece that shrinks from the front side of the second clamping piece and extends forward.

The first contact piece is located in the middle of the side of the first clamping piece, and the second contact piece is located in the middle of the side of the second clamping piece.

The outer edges of the first clamping piece and the second clamping piece are respectively provided with a plurality of thorns, and the thorns are embedded in the inner side wall of the housing and the outer side wall of the cylinder.

The end section of the first contact piece is bent towards the direction approaching the inner wall, and the end section of the second contact piece is bent towards the direction approaching the outer wall.

The first terminal also includes a first soldering piece extending downward from the rear bottom of the first clamping piece, and the second terminal also includes a first soldering piece extending downward from the rear bottom of the second clamping piece. Two welding tabs.

The power connector also includes a third terminal, and the column is provided with a third groove between the two second grooves, and the third terminal is combined in the third groove.

The third terminal includes a third clamping piece parallel to the third groove and a third contact piece extending forward from the front end of the third clamping piece.
