The self-locking grounding wire clamp of the present invention also includes two arcuate conductive clips, a movable locking piece, a movable locking piece pressure bar, a movable pull bar, a terminal block and a clip pressure spring;

The main body of the U-shaped clip body is an inverted U-shaped structure, and the inner surface of the U-shaped clip body is provided with a U-shaped groove. In the U-shaped area of the clip body, the bottom ends of the two bow-shaped conductive clips are all arranged in the U-shaped grooves on the inner surface of the U-shaped clip body, and are located on the opening side of the U-shaped clip body. The top of the piece is hinged with one end of the movable lock piece, and the other ends of the two movable lock pieces are hinged with the lower end of the movable pressure rod, and the top of the movable pressure rod passes through the top of the U-shaped clip body and the top of the movable pull rod in turn; There is a card point in the middle of the rod, and the card point is placed on the lower side of the top of the movable rod;

A spring is sleeved on the outside of the movable pull rod, and a limit baffle is arranged on the movable pull rod, and a limit baffle is arranged in the hollow structure of the U-shaped clamp body, and the limit baffle and the limit baffle are used to fix the position of the spring; the terminal block It is arranged on the outside of the U-shaped clip body, and the clip pressure spring is arranged between the bow-shaped conductive clip and the U-shaped clip body;

In the present invention, a pair of bow-shaped conductive clips are installed on both sides of the U-shaped ground wire clip slot, and the two sides of the bow-shaped conductive clips are used to tighten the wires by spring pressure respectively. The tops of the bow-shaped conductive clips are respectively equipped with movable locking pieces. By pushing up and down the opening and closing angle of the movable locking piece, the opening and closing distance of the bow-shaped conductive clips on both sides is controlled. Realize the function of clamping and releasing the grounding wire. A rectangular through hole is arranged on the top of the movable pull rod, and the movable pressing rod can move up and down through the through hole. There is a stuck point in the middle of the movable pressure rod. When the movable pull rod moves downward, the stuck point drives the movable pressure rod to move, thereby transferring the force to the movable locking piece, so that the bow-shaped conductive clip is opened at a certain angle and then locked, which is convenient for the removal of the grounding wire. , avoiding the problem of jamming easily when the grounding wire is removed.
