Electrical equipment is equipment that makes electric current do work in the process of power generation, transmission, transformation, distribution and consumption. The use of electrical equipment makes people's application of electric energy more convenient, quick and effective, while reducing the safety risks of electric energy use.

[0003] The authorization publication number "CN 220585515 U" records "a flameproof high-voltage terminal for electrical equipment, comprising a flameproof high-voltage terminal body, a mounting plate fixedly connected to the bottom of the flameproof high-voltage terminal body, a connection hole opened on the top of the flameproof high-voltage terminal body, and a limiting component provided on the flameproof high-voltage terminal body, the limiting component comprising two telescopic rods fixedly connected to the inner wall of the flameproof high-voltage terminal body. The flameproof high-voltage terminal for electrical equipment, by providing a limiting component, can fix the wire during the use of the flameproof high-voltage terminal body by pulling the tooth plate to move and placing the wire in the connection hole, and then loosening the tooth plate to move the clamping joint to the right to cooperate with the pressure plate to fix the wire, thereby eliminating the need to use special tools for operation, facilitating quick plugging and unplugging of the wire, and simplifying the operation, thereby improving the work efficiency of the staff".

[0004] The above patent effectively optimizes the connection efficiency between the terminal block and the wire, but the limiting component in the above patent has the problem of poor limiting effect. Specifically, the limiting component limits the two sides of the wire through the clamping joint and the tooth plate. Since the wires are all cylindrical in shape, if only the two sides of the wire are restricted, the wire is prone to shaking in the direction without restriction, affecting the connection stability of the wire and the terminal block.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions:

[0007] A flameproof high-voltage terminal block for electrical equipment, comprising:

[0008] A terminal body, wherein a docking plate is fixedly connected between the inner walls of the terminal body; and

[0009] The locking mechanism includes a mounting seat, the mounting seat is fixedly mounted on the inner bottom wall of the terminal body, the outer wall of the mounting seat is rotatably connected with a plurality of clamping claws, a mounting rod is movably embedded inside the mounting seat, a mounting sleeve is fixedly mounted on the outer surface of the mounting rod, a plurality of connecting rods are rotatably connected to the outer surface of the mounting sleeve, and one end of each connecting rod is rotatably connected to the corresponding clamping claw.

[0010] As a preferred solution of the utility model, a spring is fixedly connected between the mounting sleeve and the outer wall of the mounting seat.

[0011] As a preferred solution of the utility model, each outer wall of the clamping jaws is fixedly connected with an anti-slip plate, and each outer wall of the anti-slip plate is fixedly connected with a plurality of anti-slip teeth.

[0012] As a preferred solution of the utility model, the outer wall of the terminal body is provided with a mounting groove, a paddle is movably embedded in the mounting groove, and the paddle is fixedly connected to one end of the mounting rod.

[0014] As a preferred solution of the utility model, a positioning plate is fixedly connected to the outer wall of the terminal body.

[0015] Beneficial Effects

[0016] Compared with the prior art, the utility model provides a flameproof high-voltage terminal block for electrical equipment, which has the following beneficial effects:

[0017] 1. In this solution, the docking plate is used for the electrical connection between the terminal body and the wire. The lifting and lowering of the mounting rod on the mounting seat will drive the mounting sleeve and the connecting rod to lift and lower. Since the connecting rod rotates to connect the clamping claw and the mounting sleeve, and the clamping claw is rotated and connected to the mounting seat, it will drive the clamping claw to swing.
