Description

Technical Field

[0001] The utility model relates to the technical field of thyristor switches, and more specifically to a thyristor switch. Background Art

[0002] A thyristor switch, also known as a thyristor switch, is a semiconductor device used to control the flow of electric current. Thyristors can achieve precise control of circuits and are commonly used in applications such as dimming, speed regulation, and power control.

[0003] The working principle of the thyristor switch is to control the conduction and cutoff of the current by controlling the voltage between an insulating gate and a semiconductor structure. When a trigger pulse or signal is given, the thyristor can switch from the non-conducting state to the conducting state, allowing current to pass. Once the thyristor is turned on, it will remain in the conducting state until the current drops to zero or a reverse voltage is applied.

[0004] The existing thyristor switch blows air from the side, which does not conform to the law of air convection, resulting in low heat dissipation efficiency and poor heat dissipation effect, which seriously affects the long-term stable and reliable operation of the equipment. In addition, dust is easily accumulated on the heat sink, which affects heat dissipation. Excessive dust accumulation is prone to generate static electricity during use.

[0005] In addition, the existing thyristor switch is generally fixedly connected by fixing bolts. When it needs to be disassembled, it is necessary to loosen the fixing bolts with tools, which makes installation and disassembly very troublesome. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a thyristor switch to solve the problems existing in the above background technology.

[0007] The utility model provides the following technical solution: a thyristor switch, comprising a thyristor switch body, a connecting plate is installed on the right side of the thyristor switch body, a mounting assembly is installed on the right side of the connecting plate, a heat dissipation assembly is installed on the left side of the thyristor switch body, the heat dissipation assembly comprises a heat dissipation aluminum plate, a heat dissipation aluminum sheet is fixedly connected to the inner side of the heat dissipation aluminum plate, a fan assembly is installed at the bottom of the heat dissipation aluminum plate, cylindrical grooves are opened on the front and back sides of the connecting plate, a second spring is fixedly connected to the inner side of the cylindrical groove, a latch block is fixedly connected to the other end of the second spring, and the latch block is movably sleeved with the cylindrical groove.

[0008] Furthermore, the mounting assembly includes a mounting plate, the four corners of the side of the mounting plate are provided with fixing holes, the front and back sides of the left side of the mounting plate are fixedly connected to the fixing plate, a cylindrical hole is provided on the surface of the fixing hole, a cylindrical rod is movably sleeved on the inner side of the cylindrical hole, and a connecting block is fixedly connected to one end of the cylindrical rod away from the fixing plate.

[0009] Furthermore, a first spring is arranged on the outer side of the cylindrical rod, one end of the first spring is fixedly connected to the fixing plate, and the other end is fixedly connected to the connecting block, and the connecting block is fixedly connected to a limiting block in the middle near the surface of the fixing plate.

[0010] Furthermore, a rotating shaft is movably sleeved on the top of the inner side of the heat dissipation aluminum plate, and a dustproof sheet is fixedly connected to the outer side of the rotating shaft.

[0011] Furthermore, the fan assembly includes a fixing frame fixedly connected to the bottom of the heat dissipation aluminum plate, the inner side of the fixing frame is fixedly connected to the fan body, and the bottom of the inner side of the fixing frame is fixedly connected to a dustproof net.

[0012] Furthermore, the right side of the latch block away from one end of the connecting plate is an inclined surface, and the latch block and the cylindrical hole are adapted to each other.

[0013] Technical effects and advantages of the utility model:

[0014] 1. The utility model is provided with a heat dissipation component. Starting the fan body can accelerate the air flow. The low-temperature air from the outside enters through the bottom of the fixed frame. The dustproof net can filter the dust in the air to prevent the dust from adhering to the surface of the heat dissipation aluminum sheet and affecting the heat dissipation. The high-temperature air inside the heat dissipation aluminum sheet is discharged through the top of the heat dissipation aluminum plate. The dustproof sheet is offset in the vertical direction by the thrust of the air. When the heat dissipation is not performed, the dustproof sheet maintains a horizontal state under the action of its own gravity, and the top of the heat dissipation aluminum plate is closed to prevent the outside dust from falling on the surface of the heat dissipation aluminum sheet.

[0015] 2. The utility model is provided with a connecting plate and a mounting assembly. When the thyristor switch body needs to be installed, the connecting plate is inserted into the inner sides of the two fixing plates. The inclined surface of the latch block is squeezed by the fixing plates and pressed into the inner side of the cylindrical groove. When the surface of the connecting plate fits with the left side of the mounting plate, the latch block is aligned with the cylindrical hole. Under the elastic force of the second spring, the latch block extends into the inner side of the cylindrical hole to fix the connecting plate, thereby completing the installation of the thyristor switch body. When the thyristor switch body needs to be disassembled, the connecting block is pressed in the direction of the fixing plate that is close to it. When the limit block contacts the surface of the fixing plate, the cylindrical rod pushes the latch block out of the cylindrical hole, and then the connecting plate can be taken out horizontally to the left.

In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The thyristor switch involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0025] In the embodiment of the present application, the mounting assembly 3 is fixed by passing bolts through the fixing holes 302. When the thyristor switch body 1 needs to be installed, the connecting plate 2 is inserted into the inner sides of the two fixing plates 303. The inclined surface of the latch block 203 is squeezed and pressed into the inner side of the cylindrical groove 201 by the fixing plates 303. When the surface of the connecting plate 2 is in contact with the left side of the mounting plate 301, the latch block 203 is aligned with the cylindrical hole 304. Under the elastic force of the second spring 202, the latch block 203 extends into the inner side of the cylindrical hole 304 to complete the fixing of the connecting plate 2, thereby completing the installation of the thyristor switch body 1. When the thyristor switch body 1 needs to be disassembled, the connecting block 307 is pressed in the direction of the fixing plate 303 that is close to it. When the limit block 308 contacts the surface of the fixing plate 303, the cylindrical rod 305 just pushes the latch block 203 out of the cylindrical hole 304, and then the connecting plate 2 can be taken out horizontally to the left.

[0026] The heat dissipation aluminum plate 401 and the heat dissipation aluminum sheet 402 have good thermal conductivity. The heat generated by the thyristor switch body 1 is transferred to the heat dissipation aluminum plate 401 and the heat dissipation aluminum sheet 402. The heat dissipation aluminum sheet 402 has a large contact area with the air and can transfer a large amount of heat to the air, thereby dissipating the heat of the thyristor switch body 1. Starting the fan body 432 can accelerate the air flow. The low-temperature air from the outside enters through the bottom of the fixed frame 431. The dustproof net 433 can filter the dust in the air to prevent the dust from adhering to the surface of the heat dissipation aluminum sheet 402 and affecting the heat dissipation. The high-temperature air inside the heat dissipation aluminum sheet 402 is discharged through the top of the heat dissipation aluminum plate 401. The dustproof sheet 412 is offset in the vertical direction by the thrust of the air. When no heat is dissipated, the dustproof sheet 412 maintains a horizontal state under the action of its own gravity, and the top of the heat dissipation aluminum plate 401 is sealed to prevent the outside dust from falling on the surface of the heat dissipation aluminum sheet 402.

[0027] In a preferred embodiment, the mounting assembly 3 includes a mounting plate 301, and fixing holes 302 are provided at the four corners of the side of the mounting plate 301. The front and back sides of the left side of the mounting plate 301 are fixedly connected to fixing plates 303. A cylindrical hole 304 is provided on the surface of the fixing hole 302. A cylindrical rod 305 is movably sleeved on the inner side of the cylindrical hole 304. The end of the cylindrical rod 305 away from the fixing plate 303 is fixedly connected to a connecting block 307. Bolts are passed through the fixing hole 302 to fix the mounting assembly 3.

[0028] In a preferred embodiment, a first spring 306 is provided on the outer side of the cylindrical rod 305, one end of the first spring 306 is fixedly connected to the fixed plate 303, and the other end is fixedly connected to the connecting block 307. The connecting block 307 is fixedly connected to a limiting block 308 in the middle near the surface of the fixed plate 303. The first spring 306 generates a thrust on the connecting block 307, so that one end of the cylindrical rod 305 is located on the inner side of the cylindrical hole 304, thereby preventing the cylindrical hole 304 from affecting the installation of the connecting plate 2.

[0029] In a preferred embodiment, the top of the inner side of the heat dissipating aluminum plate 401 is movably sleeved with a rotating shaft 411, and the outer side of the rotating shaft 411 is fixedly connected with a dustproof sheet 412. When the fan body 432 is not working, the dustproof sheet 412 maintains a horizontal state under the action of its own gravity and fits with the top of the heat dissipating aluminum plate 402, thereby sealing the top of the heat dissipating aluminum plate 401 and preventing external dust from falling on the surface of the heat dissipating aluminum plate 402.

[0030] In a preferred embodiment, the fan assembly 403 includes a fixed frame 431 fixedly connected to the bottom of the heat dissipation aluminum plate 401, a fan body 432 is fixedly connected to the inner side of the fixed frame 431, and a dustproof net 433 is fixedly connected to the bottom of the inner side of the fixed frame 431, and the dustproof net 433 can play a dustproof role.

[0031] The working principle of the utility model is as follows: the mounting assembly 3 is fixed by passing bolts through the fixing holes 302. When the thyristor switch body 1 needs to be installed, the connecting plate 2 is inserted into the inner sides of the two fixing plates 303. The inclined surface of the latch block 203 is squeezed and pressed into the inner side of the cylindrical groove 201 by the fixing plate 303. When the surface of the connecting plate 2 fits with the left side of the mounting plate 301, the latch block 203 is aligned with the cylindrical hole 304. Under the elastic force of the second spring 202, the latch block 203 extends into the inner side of the cylindrical hole 304 to complete the fixation of the connecting plate 2, thereby completing the installation of the thyristor switch body 1. When the thyristor switch body 1 needs to be disassembled, the connecting block 307 is pressed in the direction of the fixing plate 303. When the limit block 308 contacts the surface of the fixing plate 303, the cylindrical rod 305 just pushes the latch block 203 out of the cylindrical hole 304, and then the connecting plate 2 can be taken out horizontally to the left.

[0032] The heat dissipation aluminum plate 401 and the heat dissipation aluminum sheet 402 have good thermal conductivity. The heat generated by the thyristor switch body 1 is transferred to the heat dissipation aluminum plate 401 and the heat dissipation aluminum sheet 402. The heat dissipation aluminum sheet 402 has a large contact area with the air and can transfer a large amount of heat to the air, thereby dissipating the heat of the thyristor switch body 1. Starting the fan body 432 can accelerate the air flow. The low-temperature air from the outside enters through the bottom of the fixed frame 431. The dustproof net 433 can filter the dust in the air to prevent the dust from adhering to the surface of the heat dissipation aluminum sheet 402 and affecting the heat dissipation. The high-temperature air inside the heat dissipation aluminum sheet 402 is discharged through the top of the heat dissipation aluminum plate 401. The dustproof sheet 412 is offset in the vertical direction by the thrust of the air. When no heat is dissipated, the dustproof sheet 412 maintains a horizontal state under the action of its own gravity, and the top of the heat dissipation aluminum plate 401 is sealed to prevent the outside dust from falling on the surface of the heat dissipation aluminum sheet 402.
