Description

Technical Field

[0001] This utility model relates to the field of power supply protection technology, specifically to a power supply protection device installation mechanism. Background Technology

[0002] A power supply protector is a protective device used in electrical systems. Its main function is to automatically disconnect the power supply when an abnormality occurs in the power supply circuit, protecting the circuit and equipment from damage. Power supply protectors have multiple protection functions, including overload protection, short circuit protection, phase loss protection, and phase sequence protection. Specifically, the power supply protector monitors parameters such as current and voltage in the circuit. When these parameters exceed the set range, the protector will quickly act and disconnect the power supply. For example, in the event of an overload, the power supply protector will implement inverse time protection based on the severity and duration of the overload, preventing damage to the circuit and equipment due to prolonged overload. Simultaneously, for short circuit faults, the power supply protector can also disconnect the power supply in a very short time, preventing the fault from escalating. After the power supply protector is installed in the equipment, it needs to be connected to other components via wires to monitor parameters such as current and voltage in the circuit and protect the circuit and equipment. However, the connection point between the power supply protector's port and the wire plug is easily damaged during maintenance or equipment operation. This can cause the wire plug to separate from the power supply protector's port, affecting its protective function. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a power supply protection device installation mechanism, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a power supply protection device installation mechanism, comprising an installation plate, a main unit embedded on one side of the installation plate, several plug terminals installed on both sides of the main unit, wiring terminals placed on one side of each plug terminal, a drive box fixedly connected to the surface of the main unit and on both sides of the plug terminals, a ball screw rotatably connected inside each drive box, a push block threadedly connected to the outer side of each ball screw, one end of each push block extending to the outer side of the drive box and fixedly connected to a clamping block, a worm rotatably connected inside the drive box and below the worm wheel, the worm being driven by the worm wheel, one end of each worm extending to the outer side of the drive box and fixedly connected to a screw head, the power supply protection device can be an SJDK-400 power supply protector or other models of power supply protection devices, bearings are provided inside the drive box and on the outer sides of both ends of the worm and ball screw.

[0005] Preferably, a drive groove is provided on one side of the screw head.

[0006] Preferably, the surface of the mounting plate is provided with four waist holes.

[0007] Preferably, one end of each of the wiring terminals is equipped with a plug, and one end of each plug is inserted into the socket.

[0008] Preferably, both clamps are located on opposite sides of the wiring.

[0009] Preferably, the outer sides of the push blocks are slidably connected to the inner cavity of the drive box.

[0010] This utility model provides a power supply protection device installation mechanism, which has the following advantages:

[0011] 1. The power supply protection device installation mechanism is equipped with an installation plate, a main unit, and a clamping block. Using a tool, one end of the tool is inserted into the drive groove, and then the screw head is turned through the drive groove. The screw head drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel drives the ball screw to rotate, which in turn drives the push block to move. The push block drives the clamping block to move, so that the clamping block contacts the outside of the wiring, limiting the connection between the wiring and the plug, ensuring the connection between the plug and the wiring, and preventing the plug from becoming disconnected from the wiring.

[0012] 2. The power supply protection device installation mechanism is equipped with a worm gear and a worm wheel. The self-locking property of the worm gear and the worm wheel limits the rotation of the ball screw, thereby limiting the push block and the clamping block, thus ensuring the limit at the connection between the connector and the plug.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution: a power supply protection device installation mechanism, including an installation plate 1, a main unit 3 embedded on one side of the installation plate 1, several plug terminals 4 installed on both sides of the main unit 3, wiring terminals 5 placed on one side of each plug terminal 4, a drive box 6 fixedly connected to the surface of the main unit 3 and located on both sides of the plug terminals 4, a ball screw 8 rotatably connected inside the drive box 6, a push block 10 threadedly connected to the outer side of each ball screw 8, one end of each push block 10 extending to the outer side of the drive box 6 and fixedly connected to a clamping block 11, a worm 7 rotatably connected inside the drive box 6 and located below the worm wheel 9, the worm 7 being driven by the worm wheel 9, one end of each worm 7 extending to the outer side of the drive box 6 and fixedly connected to a screw head 12.

[0021] Each side of the screw head 12 is provided with a drive groove 13, which can be matched with one end of the tool, so that by rotating the tool, the screw head 12 can be rotated through the drive groove 13.

[0022] The surface of the mounting plate 1 is provided with four waist holes 2. Tools are used to fix the mounting plate 1 to the main unit 3 through the waist holes 2.
