Description

Technical Field

[0001] The invention relates to the field of electrical safety, and in particular to a surge protector with flame retardancy, vibration resistance and moisture resistance. Background Art

[0002] A surge protector, also known as a lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other equipment in the circuit. Especially during the operation of the national power grid and high-speed trains, in order to ensure safety, surge protectors are required to work and protect against surge power.

[0003] Existing surge protector products are mostly connected to the circuit using a wire connection method similar to that of a leakage protector, but there are no corresponding protective measures for the wire connection interfaces. Dust is easily accumulated at the interfaces due to long-term use, or rainwater enters the interfaces in outdoor environments, causing poor contact, or short circuits, leakages, and further causing dangerous situations such as line fires. Safety cannot be guaranteed during use. In addition, the specific routing methods of the wires are different under various working conditions, and the routing direction needs to be adapted when connecting, which is troublesome. Secondly, the resistivity accuracy of existing surge protectors cannot be controlled. When faced with different usage conditions, the same specifications may result in untimely responses or failure to meet the actual strain. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to propose a surge protector with flame retardancy, vibration resistance and moisture resistance.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] In the above-mentioned flame-retardant, vibration-resistant and moisture-resistant surge protector, a groove is provided on the surface of the arrester, two springs are welded inside the groove, and an anti-vibration plate is welded to the other end of the spring.

[0008] In the above-mentioned flame-retardant, vibration-resistant and moisture-resistant surge protector, two connecting blocks are welded on the surface of the anti-vibration plate, and two built-in grooves are formed inside the groove, and the connecting blocks are slidably connected to the built-in grooves.

[0009] In the above-mentioned flame-retardant, vibration-resistant and moisture-resistant surge protector, a shift block is welded to one end of the latch tooth, a notch is provided on the surface of the protective cover, the shift block is slidably connected to the notch, the latch tooth is slidably connected to the notch, and the notch is slidably connected to the through slot.

[0010] In the above-mentioned flame-retardant, vibration-resistant and moisture-resistant surge protector, a reset spring is welded on one side of the shift block, and the other end of the reset spring is welded to the inner wall of the slot. A limiting groove is provided on the inner wall of the slot, and the limiting groove is slidably connected to the shift block.

[0011] In the above-mentioned flame-retardant, vibration-resistant and moisture-resistant surge protector, a top spring is welded inside the regulator, and a clamping block is welded at the other end of the top spring, and the clamping block is clamped with the lightning arrester.

[0012] In the above-mentioned flame-retardant, vibration-resistant and moisture-resistant surge protector, a moisture-proof plate is slidably connected to the surface of the arrester, and a fixing strip is inserted into the top of the moisture-proof plate.

[0013] In the above-mentioned flame-retardant, vibration-resistant and moisture-resistant surge protector, a mounting groove is provided on the surface of the lightning arrester, and a screw hole is provided on the surface of the mounting groove.

[0014] Compared with the existing technology, the advantages of the flame-retardant, vibration-resistant and moisture-resistant surge protector are:

[0015] 1. Use the sliding effect of the shift block inside the slot to drive the card teeth to slide along the through slot, so that the card teeth are separated from the rotating teeth, and adjust the use direction of the card slot to adapt it to the wiring method of the wire. Use the card slot to insert the wire to be connected into the wiring hole, and twist the terminal through the fixed groove on the surface of the lightning arrester. Use the terminal to clamp and fix one end of the wire inside the wiring hole, which can facilitate the connection work of different wiring directions. Use the protective effect of the protective cover to ensure the safety of the work;

[0016] 2. By rotating the adjustment block on the surface of the lightning arrester and utilizing the sliding effect of the connector in the slide slot, the working effect of the resistor can be determined. The resistance value can be adjusted and controlled by utilizing the amount of intervention of the sliding rheostat, thereby further achieving the purpose of controlling the resistivity. In addition, the semiconductor material of the core component of the product adopts a multi-component formula and a high-dispersion technology of micro-nano electronic powders, and the core components form a good ohmic contact technology between the core bodies of the product, which can accurately control the resistivity of the surge protector and achieve the working purpose of making the product have good linearity, low-temperature resistivity and high energy density;

[0017] To sum up, by utilizing the protective effect of the protective cover and the rotation effect of the card slot on the top of the protective cover and the rotation of the adjustment block inside the lightning arrester, the connector is driven to slide along the slide groove on the surface of the resistor to determine the intervention amount of the resistor. This can facilitate wiring, ensure the safety of the entire work, control the resistivity, and improve work results. BRIEF DESCRIPTION OF THE DRAWINGS
