[0002] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments and meters, and communication lines. A surge protector can limit the voltage overload caused by lightning, electrical system switching operations, or static electricity to a voltage range that the elevator electrical system can withstand, thereby preventing damage to the elevator electrical system caused by the above-mentioned overvoltage. It has the characteristics of large protection flow rate, extremely low residual voltage, fast response time, and stable and reliable operation.

[0003] Existing surge protectors do not have a wiring auxiliary structure. During wiring, the exposed part of the wire is very easy to fall off from the wiring hole after being inserted into the wiring hole. Therefore, the wiring worker needs to insert the exposed part of the wire into the wiring hole with one hand to support it, and use the other hand to use a tool to rotate the fastening screw to tighten the exposed part of the wire to achieve wiring. However, when large-scale wiring is required, the above wiring method is not convenient for the staff to perform wiring operations quickly. Therefore, the applicant has made a useful design and found a solution to the above problem. The technical solution to be introduced below was produced in this context. Summary of the Invention

[0028] Reference example Figures 1 to 3 A surge protector includes a housing 1, with wiring chambers 2 provided at both ends of the housing 1, the wiring chamber 2 being provided with a static conductive plate 3, the static conductive plate 3 being provided with a movable plate 4 that can be raised and lowered, a spring 5 being provided between the movable plate 4 and the static conductive plate 3 to apply an upward force to the movable plate 4, the movable plate 4 being provided with a control assembly 6 and passing through the top of the wiring chamber 2, and elastic portions 21 for clamping wires being provided on both sides of the entrance of the wiring chamber 2;

[0029] It is worth mentioning that a first through hole 22 is provided on the top of the wiring chamber 2, and the first through hole 22 provides a guide for the insulating rod 62 to rise and fall;

[0030] It is worth mentioning that the static conductive plate 3 is provided with a pressure-bearing surface 31, the pressure-bearing surface 31 is provided with a plurality of equally spaced protrusions 32, the static conductive plate 3 is provided with a countersunk hole 33, the static conductive plate 3 is provided with a limiting portion 34, the limiting portion 34 is provided with a second through hole 35, the protrusion 32 serves to increase the friction between the exposed portion of the wire and the countersunk hole 33, prevents the spring 5 from detaching, the limiting portion 34 limits the rising distance of the movable plate 4, and the second through hole 35 provides a guide for the screw 61 to rise and fall;

[0031] It is worth mentioning that the movable plate 4 is provided with a resistance portion 41, which abuts against the protrusion 32. The movable plate 4 is provided with a cylinder 42, which is arranged opposite to the resistance portion 41. A threaded hole 43 is provided on the back of the cylinder 42. The resistance portion 41 cooperates with the protrusion 32 to prevent the spring 5 from detaching. At the same time, the cylinder 42 cooperates with the countersunk hole 33 to limit the distance that the movable plate 4 descends, preventing the elastic potential energy of the spring 5 from decreasing. The threaded hole 43 facilitates the connection between the screw 61 and the movable plate 4.

[0032] It is worth mentioning that the control assembly 6 includes a screw 61 and an insulating rod 62. The screw 61 passes through the first through hole 22 and the second through hole 35 and is threadedly connected to the threaded hole 43. The insulating rod 62 is threadedly connected to the screw 61. The insulating rod 62 is provided with a pressing portion 621. The pressing portion 621 maintains a downward pressure distance from the top of the housing 1. The insulating rod 62 prevents workers from accidentally getting an electric shock. The pressing portion 621 facilitates operation by wiring personnel. When the pressing portion 621 abuts against the top of the housing 1, the distance that the movable plate 4 can descend is limited.

[0033] It is worth mentioning that the spring 5 is disposed on the outer wall of the cylinder 42 and abuts against the counterbore 33 .

[0034] The operating principle of the present invention is now described as follows:

[0035] Applying downward pressure to the pressing portion 621 squeezes the spring 5 and stores energy. A gap is formed between the protrusion 32 and the abutment portion 41 to accommodate the exposed portion of the wire. The insulation layer of the wire is pushed into the elastic portion 21 through the entrance. The elastic force released by the elastic portion 21 forms a force that clamps the wire, thereby improving the stability of the electrical connection between the wire and the housing 1.

[0036] At this time, the exposed part of the wire enters between the movable plate 4 and the static conductive plate 3, and the force applied to the pressing part 621 is released. The elastic force released by the spring 5 is applied to the movable plate 4, so that a clamping force is formed between the protrusion 32 and the contact part 41 to clamp the exposed part of the wire.

[0037] The above design solution can enable the product to achieve the advantage of improving wiring efficiency.

[0038] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
