[0002] Electrical equipment refers to equipment that uses electrical energy to complete specific functions. It is widely used in industrial, commercial and home environments. An electrical equipment protector is a device used to protect electrical equipment from power system failures and abnormal operating conditions. It can detect abnormalities in parameters such as current, voltage, frequency, and temperature, and quickly cut off power when potential dangerous conditions are detected to prevent equipment damage and personal safety accidents. Common electrical equipment protectors include circuit breakers, fuses, leakage protectors, etc.

[0003] A Chinese patent publication (publication number: CN214336669U) discloses a highly sensitive anti-interference leakage protector, including a leakage protector component compartment body, wherein an incoming power supply fixing compartment is fixedly installed on the upper surface of the leakage protector component compartment body, an incoming power supply fixing compartment screw rotating base is fixedly installed near the rear surface of the incoming power supply fixing compartment, an internal threaded blind hole is provided at the middle position of the front surface of the incoming power supply fixing compartment screw rotating base, and an incoming power supply lead metal sheet is fixedly installed on the front surface of the incoming power supply fixing compartment screw rotating base. The highly sensitive anti-interference leakage protector described in the utility model can make the leakage protector resistant to electromagnetic interference, reduce the influence of surrounding components and equipment on leakage protection, improve safety, and can seal the incoming wires to prevent a large amount of dust from being generated during long-term operation in harsh environments, resulting in a short circuit at the incoming wire;

The quick-release assembly 3 includes a first U-shaped rod 301, a clamping plate 302, a guide column 303, a groove 304, a spring 305 and a second U-shaped rod 306.

[0024] In one embodiment, a rubber gasket 5 is fixedly attached to the rear side of the housing 2 , and the rear side of the rubber gasket 5 is in active contact with the front side of the wiring socket 1 . The rubber gasket 5 is provided to improve the sealing between the housing 2 and the wiring socket 1 .

[0025] In one embodiment, a first U-shaped rod 301 is movably provided on the front side of the wiring socket 1, and a second U-shaped rod 306 is movably provided on the front side of the wiring socket 1. The second U-shaped rod 306 is symmetrically arranged with the first U-shaped rod 301. A clamping plate 302 is fixedly installed on the inner wall of the side where the first U-shaped rod 301 and the second U-shaped rod 306 are close to each other. A clamping hole 6 is provided on the top and bottom of the inner wall of the shell 2. The clamping plate 302 cooperates with the clamping hole 6. Two grooves 304 are provided on the lower surface of the first U-shaped rod 301. A guide column 303 is movably provided inside the groove 304. The bottom end of the guide column 303 extends to the top of the first U-shaped rod 301. The top of the guide column 303 is fixedly connected to the upper surface of the second U-shaped rod 306. The outer side of the guide column 303 is movably connected to the inner wall of the groove 304. The second U-shaped rod 306 is in dynamic contact, and a spring 305 is fixedly connected to the upper surface of the second U-shaped rod 306, and the top of the spring 305 is fixedly connected to the lower surface of the first U-shaped rod 301, and the spring 305 is wound around the outer side of the guide column 303. By pulling the first U-shaped rod 301, the first U-shaped rod 301 moves upward along the guide column 303 under the action of the groove 304, and the first U-shaped rod 301 drives the clamping plate 302 to separate from a clamping hole 6. When the first U-shaped rod 301 moves upward, the spring 305 is stretched, and then the second U-shaped rod 306 is pulled downward, so that the second U-shaped rod 306 drives the guide column 303 to move downward, and the spring 305 is stretched when the second U-shaped rod 306 moves downward, until the second U-shaped rod 306 drives the clamping plate 302 to separate from a clamping hole 6, thereby releasing the fixation of the shell 2.

[0026] In one embodiment, four T-shaped guide grooves 4 are provided on the front side of the terminal block 1, and the four T-shaped guide grooves 4 are symmetrically arranged in pairs. Two T-shaped guide blocks 8 are fixedly installed on the rear sides of the first U-shaped rod 301 and the second U-shaped rod 306, and the T-shaped guide blocks 8 cooperate with the T-shaped guide grooves 4. The rear sides of the first U-shaped rod 301 and the second U-shaped rod 306 are in active contact with the front side of the terminal block 1. The movement of the first U-shaped rod 301 and the second U-shaped rod 306 is guided by the arrangement of the T-shaped guide blocks 8 and the T-shaped guide grooves 4.

[0027] When the utility model is in operation: during use, the shielding layer 7 is provided to reduce the influence of external electromagnetic interference or radio frequency interference on the protector of the electrical equipment. When the shell 2 needs to be disassembled for maintenance and inspection of the interior of the terminal block 1, the first U-shaped rod 301 is pulled upward, and the spring 305 is stretched while the first U-shaped rod 301 is pulled upward. At this time, the first U-shaped rod 301 drives the clamping plate 302 located on the top of its inner wall to separate from the clamping hole 6 located on the top of the inner wall of the shell 2, and then the second U-shaped rod 306 is pulled downward. While the second U-shaped rod 306 moves, it drives the guide column 303 to move out from the inside of the groove 304. The second U-shaped rod 306 moves and the spring 305 is stretched. At this time, the second U-shaped rod 306 drives the clamping plate 302 located on the bottom of its inner wall to separate from the clamping hole 6 located on the bottom of the inner wall of the shell 2, and the fixation of the shell 2 can be released.
