Description

Technical Field

[0001] The utility model relates to the technical field of surge protectors, in particular to an anti-static interference type surge protector. Background Art

[0002] A surge protector, also known as a surge protector or SPD, is an electronic device used to suppress abnormal overvoltage and instantaneous overcurrent in a circuit to avoid damage to electrical equipment. Its main function is to suppress conducted interference, reduce noise, and suppress the generation and radiation of surge waveforms to protect electronic equipment.

[0003] With the rapid development of modern electronic technology, the stable operation of electronic equipment in various complex environments has become particularly important. Among them, anti-static interference surge protectors are key devices to protect electronic equipment from damage by static electricity and surges. The stability and reliability of their performance are directly related to the safe operation of the entire system. In high temperature environments, electronic equipment is more susceptible to static electricity interference. The generation of static electricity may not only come from the accumulation of charge inside the equipment, but also from temperature changes in the external environment. When the temperature rises, the moisture in the air evaporates, reducing the relative humidity in the air, thereby increasing the possibility of static electricity generation. In addition, high temperature may also accelerate the aging of internal components of the equipment, further increasing the risk of static electricity interference.

[0004] Chinese patent document CN210577780U discloses a surge protector base, including a base body, the front side of the base body is provided with a card slot and a mounting slot from top to bottom, the inner bottom wall of the mounting slot is provided with a slide slot and a fixing slot from left to right, and a connecting piece is inserted into the fixing slot; however, the following defects still exist in the implementation process:

[0005] Although the device in the above document can double-fix the surge protector, which not only fixes it more firmly but also facilitates disassembly and assembly, the device in the above document cannot reduce the interference of static electricity on the surge protector when it is running in a high temperature environment. Utility Model Content

[0006] The purpose of the utility model is to provide an anti-static interference type surge protector to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] The invention discloses an anti-static interference type surge protector, comprising a base body and a replaceable module; the base body and the replaceable module are plug-connected, the upper part of the base body and the lower part of the base body are symmetrically provided with mounting holes, the inner cavity of the mounting holes is fixedly connected with a clamping block assembly, the lower part of the base body is symmetrically provided with a heat dissipation assembly, the heat dissipation assembly is used to dissipate heat from the lower part of the base body, the heat dissipation assembly comprises a second shell, the inner cavity of the second shell is slidably connected with a baffle, the upper end of the baffle is symmetrically fixedly connected with a second spring, the side of the second spring away from the baffle is fixedly connected with the lower end of the base body, the lower part of the baffle is symmetrically slidably connected with a limiting cylinder, the lower end of the base body is fixedly connected with a bottom block, and the lower end of the limiting cylinder is fixedly connected with the upper end of the bottom block.

[0009] A further improvement of the technical solution of the utility model is that a heat conducting block is fixedly connected to the upper part of the base body and the lower part of the base body, and the heat conducting block is made of copper material.

[0010] The above-mentioned technical scheme is adopted, in which the upper part of the base body is connected to the lower part of the base body by a heat-conducting block, so that in a high-temperature environment, the heat of the upper part of the base body can be guided to the lower part through the heat-conducting block, and then the heat dissipation component is used to dissipate the heat, thereby reducing the static electricity generated inside the base body in a high-temperature environment. At the same time, since the base body is made of copper material, when static electricity is generated in the upper part of the base body, the heat-conducting block can be used to guide the static electricity to the lower part of the base body. Since the lower part of the base body is connected to the ground wire, the static electricity can be discharged, thereby reducing the interference of static electricity on the device.

[0011] A further improvement of the technical solution of the utility model is that the outer surface of the base body and the inner cavity of the base body are coated with a tin oxide conductive coating.

[0012] The above technical solution is adopted. In this solution, since tin oxide, as a semiconductor compound, has excellent static conductive properties, the static charge on the surface of the base body can be quickly conducted away, thereby avoiding potential damage to the equipment caused by static electricity accumulation.

[0013] A further improvement of the technical solution of the utility model is that the inner cavity of the limiting cylinder is filled with an expansion block made of silicone rubber material.

In this scheme, since the inner cavity of the limit cylinder is filled with an expansion block, the expansion block collides after being heated, and then the expansion range is limited by the limit cylinder to guide it to expand upward, so that the expansion block can be used to push the baffle to move upward, and then the heat dissipation hole is removed, and then the heat inside the base body is dissipated, thereby cooling the inside of the base body and avoiding the generation of a large amount of static electricity due to excessively high temperature inside the base body.

[0015] A further improvement of the technical solution of the utility model is that a plurality of heat dissipation holes are provided in the middle of the second shell.

[0016] The above technical solution is adopted, in which a plurality of heat dissipation holes are provided, so that the heat inside the base body can be quickly dissipated to the outside, thereby facilitating cooling thereof.

[0018] The above technical solution is adopted, in which the outer shell is threadedly connected to the threaded block, so that the position of the threaded block in the inner cavity of the outer shell can be changed by rotating the threaded block, and then the elastic block assembly is pushed to move, so that the ground wire can be quickly fixed and the ground wire can be replaced easily.

[0019] A further improvement of the technical solution of the utility model is that the elastic block assembly includes a protrusion, a side of the protrusion close to the threaded block is fixedly connected to a spring 1, a side of the spring 1 close to the threaded block is fixedly connected to a connecting block, and the connecting block is rotatably connected to the threaded block.

[0020] The above technical solution is adopted, in which the connecting block and the threaded block are rotatably connected, so that when the threaded block rotates, it can drive the connecting block to move instead of rotating, thereby preventing the elastic block assembly from causing damage to the ground wire when the ground wire is docked. The elastic force of spring 1 can push the protrusion to move, so that when the ground wire is docked, the protrusion can be quickly pushed to limit the position of the ground wire, thereby facilitating the installation of the ground wire.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides an anti-static interference type surge protector, which can guide the heat and static electricity on the upper part of the base body to the lower part through the heat conductive block, and dissipate the heat through a plurality of heat dissipation holes, so that the inside of the base body can be cooled and dissipated, thereby reducing the generation of static electricity; the static electricity transmitted to the lower part of the base body can be discharged through the ground wire, thereby reducing the time that the static electricity stays in the inner cavity of the base body, and then reducing the interference of static electricity on the device; the baffle can be used to block the heat dissipation holes when the device does not need to dissipate heat, thereby preventing external dust from entering the base body through the inner cavity of the plurality of heat dissipation holes, and then causing damage to the electronic components inside the base body.

[0043] The following is a detailed description of the working principle of the anti-static interference surge protector.

[0044] like Figure 1-7 As shown, when it is necessary to install a ground wire on the base body 1, since the upper and lower parts of the base body 1 are symmetrically provided with connecting grooves, the pole piece of the ground wire can be placed in the inner cavity of the base body 1 through the connecting groove, and then the pole piece of the ground wire will exert a force on the protrusion 321, and then the protrusion 321 will be pushed to move in the direction away from the pole piece, and then the spring 1 322 will be driven to contract, and then the spring 1 322 will push the protrusion 321 to move in the direction of the pole piece under the elastic force of the spring 1 322 itself, and then the protrusion 321 will be pushed to move in the direction of the pole piece, and then the end of the protrusion 321 close to the pole piece and enter the center hole of the pole piece, so that under the elastic force of the connecting block 323, the position of the ground wire can be limited, and then the position of the threaded block 33 in the inner cavity of the shell 1 31 is adjusted by rotating the threaded block 33, and the elastic block assembly 32 is pushed to move in the direction of the pole piece, so that the elastic block assembly 32 can be pushed by the threaded block 33 to lock the pole piece of the ground wire, and the clamping block assembly 3 can be used to install the ground wire without the help of other auxiliary tools, thereby improving work efficiency;
