Description

Technical Field

[0001] The utility model relates to the technical field of surge protectors, in particular to an explosion-proof surge protector. Background Art

[0002] A surge protector, also known as a surge protector, is an electronic device used to suppress abnormal overvoltage and instantaneous overcurrent in a circuit to avoid damage to electrical equipment. It can detect the presence of a surge in the circuit and take appropriate measures to prevent the surge from damaging the equipment. The working principle of a surge protector is based on limiting voltage and shunting current. When an abnormal spike pulse or surge current appears in the circuit, the nonlinear element in the surge protector will quickly reduce its resistance and direct the excess energy to the ground, thereby protecting the equipment.

[0003] The main function of a surge protector is to protect electrical equipment from damage caused by transient overvoltages and surge currents caused by lightning, power grid switching or other factors. In hazardous environments such as explosion-proof control boxes, these transient overvoltages and surge currents may be more severe, so surge protectors need to have explosion-proof functions to ensure that they can still effectively protect equipment under extreme conditions. In order to protect equipment safety, prevent explosion risks, ensure personnel safety and comply with regulatory requirements, when selecting and using surge protectors, the appropriate explosion-proof level and performance parameters should be selected according to specific application scenarios and needs.

[0004] When an existing surge protector is connected to a cable, the cable is generally installed and fixed by bolts to connect the two. After the bolts are used for a long time, they are easy to fall off due to vibration or impact, which can easily cause the cable and the surge protector to loosen and detach. At this time, if the cable and the surge protector are not firmly and stably connected, this will easily affect the use of the surge protector. Therefore, it is necessary to propose an explosion-proof surge protector to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an explosion-proof surge protector to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A kind of explosion-proof surge protector comprises a surge protector body; a plurality of first bolts are threadedly installed at one end of the interior of the surge protector body, a second bolt is threadedly connected to one end of the interior of the surge protector body at the bottom of each first bolt, a plurality of cables are plugged into the top of the surge protector body, a baffle is slidably installed at one end of the surge protector body at one end of each first bolt through a fixed block, a limiting component for limiting the position of each baffle is provided at the bottom of each baffle, a partition is slidably installed at one end of the surge protector body at one end of the second bolt through a connecting block, and a clamping component for limiting the position of the partition is provided on one side of the partition.

[0008] By installing the fixing block, the sliding trajectory of the baffle at one end of the surge protector body can be guided and limited, thereby ensuring that the baffle can block and limit the first bolt from one end, preventing the first bolt from falling off due to vibration or impact, thereby improving the stability of the installation between the cable and the surge protector body; by installing the connecting block, the sliding trajectory of the partition at one end of the surge protector body can be guided and limited, thereby ensuring that the baffle can block and limit the second bolt from one end, preventing the second bolt from falling off due to vibration or impact, thereby reducing arcs and sparks generated by poor contact between the cable and the surge protector body, thereby achieving an explosion-proof effect.

[0009] A further improvement of the technical solution of the utility model is that a first fixing ring is fixedly installed on the top of the surge protector body outside each cable, a second fixing ring is rotatably installed on one side of each first fixing ring, each second fixing ring is respectively fitted with the outer surface of each cable, a fixing plate is fixedly installed on the top of each second fixing ring, and each fixing plate is respectively fitted with the surface of the top of each first fixing ring, a rubber block is attached to the top of each first fixing ring at one end of each fixing plate, and the surface of the other end of each rubber block is respectively fitted with the surface of one end of each fixing plate.

[0010] The above technical solution is adopted. In this solution, the position of the cable on the top of the surge protector body can be limited by using the first fixing ring and the second fixing ring, wherein the position of the second fixing ring on one side of the first fixing ring can be limited by clamping the rubber block on one end of the fixing plate, thereby improving the stability of the cable on the top of the surge protector body, and the rubber block itself can be deformed and rebound. When the cable 9 needs to be disassembled, the rubber block can be squeezed by pushing the fixing plate toward one end to facilitate the rotation operation of the second fixing ring.

[0011] A further improvement of the technical solution of the utility model is that each limiting component includes a fixing frame, which is located at the bottom of the baffle and fixedly connected to one end of the surge protector body; a limiting plate is fixedly installed on the top of the fixing frame at one end of the baffle, and the surface of the other end of the limiting plate is in contact with the surface of one end of the baffle; a limiting block is slidably installed inside the limiting plate through a first spring, and the limiting block is engaged with one end inside the baffle; a first pull ring is provided at one end of the limiting plate, and the other end of the first pull ring extends into the interior of the limiting plate and the first spring and is fixedly connected to one end of the limiting block.

[0012] The above-mentioned technical solution is adopted. In this solution, the elastic force of the first spring itself can squeeze the limit block toward the other end, and squeeze the limit block into the interior of the baffle, so that the baffle can be limited to prevent the baffle from sliding to the top due to external force or other reasons and being unable to block one end of the first bolt, thereby improving the effect of the baffle on blocking the first bolt.

[0013] A further improvement of the technical solution of the utility model is that: the other end of the top of the limit block is provided with an inclined surface inclined toward the bottom.

[0014] The above-mentioned technical solution is adopted. In this solution, by opening a slope at the other end of the top of the limit block, when the baffle is located at the top of the limit plate, by pushing the baffle downward, the baffle can automatically squeeze the slope of the limit block so that it is squeezed into the inside of the limit plate, thereby quickly fitting the baffle to the top of the fixed frame without pulling the limit block to one end first, thereby reducing the operating steps and facilitating the downward movement and use of the baffle.

[0015] A further improvement of the technical solution of the utility model is that a friction strip is attached to the surface of one end of the baffle, and the friction strip is located on the top of the limiting plate.

[0016] The above technical solution is adopted. In this solution, the friction between the user's hand and the surface of one end of the baffle can be increased by installing a friction strip, thereby facilitating manual movement of the baffle upward or downward to prevent slipping.

[0017] A further improvement of the technical solution of the utility model lies in that: the locking component includes a connecting frame, which is located on one side of the partition and fixedly connected to one end of the surge protector body; a locking plate is fixedly installed on the other side of the connecting frame at one end of the partition; the surface of the other end of the locking plate is in contact with the surface of one end of the partition; a locking block is slidably installed inside the locking plate through a second spring; the locking block is mutually locked with one end inside the partition; a second pull ring is provided at one end of the locking plate; the other end of the second pull ring extends into the interior of the locking plate and the second spring and is fixedly connected to one end of the locking block.

[0018] The above-mentioned technical solution is adopted. In this solution, the elastic force of the second spring itself can squeeze the block toward the other end and squeeze the block into the interior of the partition, so that the partition can be limited to prevent the partition from sliding to the top due to external force or other reasons and being unable to block the second bolt from one end, thereby improving the blocking effect of the partition on the second bolt.

[0019] A further improvement of the technical solution of the utility model is that: the other end of the other side of the clamping block is provided with an inclined surface inclined to one side.

[0020] The above-mentioned technical solution is adopted. In this solution, by opening a slope at the other end of the other side of the card block, when the partition is located on the other side of the locking plate, by pushing the partition to one side, the partition can automatically squeeze the slope of the card block so that it is squeezed into the inside of the locking plate, thereby quickly fitting the partition to the other side of the connecting frame without pulling the card block to one end first, thereby reducing the operating steps and facilitating the movement and use of the partition to one side.

[0021] A further improvement of the technical solution of the utility model is that an anti-slip strip is attached to the surface of one end of the partition, and the anti-slip strip is located on the other side of the clamping plate.

[0022] By adopting the above technical solution, in this solution, the friction between the user's hand and the surface of one end of the partition can be increased by installing an anti-slip strip, thereby facilitating manual movement of the partition to one side or the other to prevent slipping.

[0023] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0024] 1. The utility model provides an explosion-proof surge protector. Through the cooperation between the fixing block and the baffle, it can ensure that the baffle blocks and limits the first bolt from one end to prevent the first bolt from falling off due to vibration or impact, thereby improving the stability of the installation between the cable and the surge protector body; through the cooperation between the connecting block and the partition, it can ensure that the partition blocks and limits the second bolt from one end to prevent the second bolt from falling off due to vibration or impact, thereby achieving an explosion-proof effect.

[0025] 2. The utility model provides an explosion-proof surge protector, which can limit the positions of the baffle and the partition at one end of the surge protector by setting a limiting component and a clamping part, thereby preventing the baffle and the partition from sliding due to external force or other reasons, thereby improving the blocking effect of the baffle and the partition on the first bolt and the second bolt, and further improving the explosion-proof effect.

[0026] 3. The utility model provides an explosion-proof surge protector. By fixing the first fixing ring and the second fixing ring on the periphery of the cable, the position of the cable on the top of the surge protector body can be limited, thereby improving the stability of the cable installed on the top of the surge protector body, ensuring that the connection between the cable and the surge protector is firm and reliable, thereby reducing the poor contact between the cable and the surge protector body caused by loosening and falling off, thereby avoiding the generation of arcs and sparks, and achieving an explosion-proof effect.
