[0006] The present invention provides a high-frequency thyristor, which specifically includes: a high-frequency thyristor main body; two cable wires are welded on the high-frequency thyristor main body, and a clamping component is installed on the high-frequency thyristor main body.

[0007] Further, the clamping component is composed of a connection block, a second fixing screw, an adjustment groove, a guide rod, and a clamping block. A connection block is fixed on the high-frequency thyristor main body through two second fixing screws. Two stepped shaft-shaped guide rods slide on the connection block. One end of the lower part of the two guide rods is welded to the top surface of the clamping block. The two cable wires are located between the connection block and the clamping block.

[0008] Further, a fixing component is installed on the high-frequency thyristor main body. The fixing component is composed of a fixing block and a first fixing screw. Two fixing blocks are welded on the high-frequency thyristor main body, and a first fixing screw for fixing the high-frequency thyristor main body is inserted into each fixing block.

[0009] Further, when the two first fixing screws are fixed on the mounting seat of the high-frequency thyristor body, the bottom end surface of the clamping block is in elastic contact with the mounting seat, and at this time, the two cable wires are in a clamped state.

[0010] Further, both of the fixing blocks are L-shaped block structures, and the outer walls of the adjustment parts of the two first fixing screws are respectively in elastic contact with the inner sides of the two fixing blocks.

By the fixing blocks pressing against the first fixing screws, the probability of the first fixing screws loosening can be reduced. Compared with the existing device, this device can effectively prevent the high-frequency thyristor body from loosening.

[0020] This application is provided with a protection assembly. Through the setting of the protection assembly, on the one hand, when the high-frequency thyristor body accidentally falls to the ground, the contact between the protection seat and the ground can prevent the high-frequency thyristor body from being bumped and damaged; on the other hand, the through holes arranged in an annular array can reduce the influence of the protection seat on the heat dissipation of the high-frequency thyristor body, ensuring that the high-frequency thyristor body can dissipate heat sufficiently. Compared with the existing device, this device is safer.

[0021] This application is provided with a protective sleeve and heat dissipation grooves. Through the setting of the protective sleeve and heat dissipation grooves, on the one hand, since a ring-shaped protective sleeve is adhered to the outside of the high-frequency thyristor body and the protective sleeve is made of rubber, when the high-frequency thyristor body accidentally falls, the protective sleeve can achieve the bump protection of the high-frequency thyristor body; on the other hand, since heat dissipation grooves are arranged in an annular array on the outer wall of the high-frequency thyristor body and the heat dissipation grooves are in contact with the protective sleeve, the heat dissipation effect of the high-frequency thyristor body can be improved through the heat dissipation grooves, and the influence of the protective sleeve on the heat dissipation of the high-frequency thyristor body can be reduced.

[0043] Wherein, the clamping assembly 3 is composed of a connection block 301, a second fixing screw 302, an adjustment groove 303, a guide rod 304 and a clamping block 305. A connection block 301 is fixed on the high-frequency thyristor body 1 by two second fixing screws 302. Two stepped shaft-shaped guide rods 304 slide on the connection block 301. One end of the lower part of the two guide rods 304 is welded to the top surface of the clamping block 305. The two cable wires 101 are located between the connection block 301 and the clamping block 305.

[0044] Among them, a fixing component 2 is installed on the high-frequency thyristor body 1. The fixing component 2 is composed of a fixing block 201 and a first fixing screw 202. Two fixing blocks 201 are welded on the high-frequency thyristor body 1, and a first fixing screw 202 for fixing the high-frequency thyristor body 1 is inserted into each fixing block 201.

[0045] Among them, when the two first fixing screws 202 are fixed on the mounting seat of the high-frequency thyristor body 1, the bottom end surface of the clamping block 305 is elastically in contact with the mounting seat, and at this time, the two cable wires 101 are in a clamped state. During fixing, the two cable wires 101 are passed through between the connecting block 301 and the clamping block 305, and the two first fixing screws 202 are screwed tightly onto the mounting seat using a wrench. At this time, the cable wires 101 are clamped synchronously by the connecting block 301 and the clamping block 305, avoiding the cable wires 101 being pulled and disconnected from the high-frequency thyristor body 1.

[0046] Among them, the two fixing blocks 201 are both L-shaped block structures, and the outer walls of the adjustment parts of the two first fixing screws 202 are elastically in contact with the inner sides of the two fixing blocks 201 respectively. During use, by the fixing block 201 pressing against the first fixing screw 202, the probability of the first fixing screw 202 loosening can be reduced.

[0047] Among them, the adjustment parts of the two second fixing screws 302 are both hexagonal structures, and an adjustment groove 303 is opened at the adjustment part of each second fixing screw 302. The two adjustment grooves 303 are both hexagonal groove structures. During the installation and removal of the second fixing screw 302, when the outside of the adjustment part of the second fixing screw 302 is knocked, a hexagonal wrench can be inserted into the adjustment groove 303 and rotated. At this time, the emergency adjustment of the second fixing screw 302 can be realized.

[0048] Among them, a protection component 4 is installed on the high-frequency thyristor body 1. The protection component 4 is composed of a connecting rod 401, a protection seat 402 and a through hole 403. Two connecting rods 401 are welded on the top end surface of the high-frequency thyristor body 1. The two connecting rods 401 are both cylindrical rod structures.

The outer diameter of the protection seat 402 is larger than the outer diameter of the high-frequency thyristor body 1. The protection seat 402 is a protection part for the high-frequency thyristor body 1. When the high-frequency thyristor body 1 accidentally falls to the ground, the contact between the protection seat 402 and the ground can prevent the high-frequency thyristor body 1 from being knocked and damaged.

[0049] Among them, through holes 403 are formed in an annular array on the top surface of the protective seat 402. The through holes 403 are in an arc-shaped hole structure. During use, the through holes 403 formed in the annular array can reduce the influence of the protective seat 402 on the heat dissipation of the high-frequency thyristor body 1, ensuring that the high-frequency thyristor body 1 can dissipate heat sufficiently.

The four support rods 104 are all in a stepped structure. When the four support rods 104 are in contact with the mounting seat, the bottom of the high-frequency thyristor body 1 is in a suspended state. During use, the support of the support rods 104 can ensure sufficient heat dissipation at the bottom of the high-frequency thyristor body 1.

[0055] The specific usage method and function of this embodiment: During the installation and removal of the second fixing screw 302 on the connecting block 301, when the outside of the second fixing screw 302 is bumped, a hexagon wrench can be inserted into the adjustment groove 303 and rotated, and at this time, the emergency adjustment of the second fixing screw 302 can be realized; when the device is fixed, two cable wires 101 are passed through between the connecting block 301 and the clamping block 305, and the two first fixing screws 202 are screwed tightly onto the mounting seat with a wrench.
