Abstract

The invention discloses a double-sealed ceramic high-voltage DC contactor, which relates to the technical field of high-voltage DC contactors. It includes a contactor body. The upper surface of the contactor body is symmetrically provided with terminals, and the outer surface of the terminals is threadedly connected with a compression nut. When the wire is compressed by the compression nut, the limit column is separated from the limit rod at the same time, so that the upper end of the rotating pressure rod rotates and presses to the top of the compression nut, thereby increasing the upward pressure of the compression nut under the downward pressure of the rotation pressure rod. The resistance during movement also increases the friction when the compression nut rotates, thereby preventing the compression nut from loosening due to vibration when it is affected by external forces, and improves the fixing effect and compression of the compression nut when used. The stability of the nut during use also makes the fixing effect between the guide and the terminal block more reliable, increasing the safety when using the double-sealed ceramic high-voltage DC contactor.

Compared with the existing technology, the present invention provides a double-sealed ceramic high-voltage DC contactor, which has the following beneficial effects:

1. When the wire is compressed by the compression nut, the limit column is separated from the limit rod at the same time, so that the upper end of the rotating pressure rod rotates and presses to the top of the compression nut, thereby increasing the compression under the downward pressure of the rotating pressure rod. The resistance when the nut moves upward also increases the friction when the compression nut rotates, which can prevent the compression nut from loosening easily due to vibration when it is affected by external forces, and improves the fixation effect and performance of the compression nut when used.

Among them: the silicone pad 501 is made of silicone and is used to absorb and disperse the impact force received by the contactor body 1, and to provide auxiliary protection to the contactor body 1.

In the existing technology, because the material of the double-sealed ceramic high-voltage DC contactor is ceramic, one of its characteristics is that it is highly brittle, and because most of the ceramic high-voltage DC contactors are fixedly installed without any buffer protection structure, Therefore, when the ceramic high-voltage DC contactor is impacted by an external force, it may be damaged. Compared with the existing technology, in the implementation of this embodiment, when the contactor body 1 is impacted by an external force, the impact will be transmitted to the silicone pad 501 on the contactor body 1, the silicone pad 501 will deform and quickly return to its original shape, absorb and disperse the impact force at the same time, and then dissipate the vibration energy, thereby reducing the impact force on the contactor body 1, protecting the contactor body 1, and increasing the contactor body 1 of durability.

Everything through the above examples works as follows:

In the initial state: under the clamping limit between the limiting column 411 and the limiting rod 416, the limiting rod 416 and the rotating pressure rod 413 cannot rotate. At this time, the torsion spring 415 is in a torsion state.

The following is the working process of the anti-loosening reinforcement mechanism to install reinforced wires:

When in use, the staff first wraps the wire around the outer surface of the terminal 2, and then rotates the compression nut 3 to move downward along the terminal 2 and compress the wire. When the compression nut 3 rotates toward When moving downward, the bottom of the compression nut 3 will press down one end of the rotating rod 408, causing the rotating rod 408 to rotate with its middle part as the center of the circle, causing one end of the rotating rod 408 to rotate downward and the other end to rotate upward. When the other end of the rotating rod 408 moves upward, When rotating, the other end of the rotating rod 408 will push the linkage column 403 and the counterweight slide rod 402 to move upward. When the counterweight slide rod 402 moves upward, the bottom of the counterweight slide rod 402 drives the connecting rod 406 to rotate. At this time, the connecting rod Under the action of 406, the connecting rod 406 pushes the slider 405 and the arc-shaped clamping rod 407 toward the guide on the outer surface of the terminal 2, and then clamps the outer surface of the wire. At this time, the wire is under the compression nut 3 The pressure clamping and arc-shaped clamping rods 407 clamp the outer surface, increasing the fixing angle of the conductor, and at the same time providing fixed points for multiple positions of the conductor. Multiple fixed points can support and complement each other, thereby improving It has a fixing effect on the wire, and at the same time prevents the wire from loosening or loosening when the wire is connected to the terminal block 2, avoids overlapping of the wire and poor contact, and improves the stability of the wire and the terminal block 2 when used;

Further, when the rotating rod 408 rotates, one end of the rotating rod 408 will gradually approach the pushing piece 410 and push the pushing piece 410 and the movable block 409 to move upward. When the pushing piece 410 moves upward, the pushing piece 410 approaches and squeezes the triangular block 412 , when the pushing piece 410 presses the triangular block 412 upward, since the bottom of the triangular block 412 is an inclined surface, the pushing piece 410 will squeeze the inclined surface of the triangular block 412, thereby driving the limiting column 411 under the guidance of the inclined surface of the triangular block 412. Move in the direction away from the limit rod 416. When the compression nut 3 compresses the wire, the limit column 411 is disconnected from the limit rod 416 at the same time. At this time, under the torsional rebound of the torsion spring 415, the rotation pressure is driven. The rod 413 rotates downward with the fixed column 414 as the center of the circle, so that the upper end of the rotating pressure rod 413 rotates and presses to the top of the compression nut 3, thereby increasing the pressure of the compression nut 3 when the compression nut 3 moves upward under the downward pressure of the rotation pressure rod 413. resistance, and at the same time increases the friction force when the compression nut 3 rotates, thereby preventing the compression nut 3 from being easily loosened due to vibration when it is affected by external forces, and improves the fixing effect and compression of the compression nut 3 during use. The stability of the nut 3 makes the fixing effect between the guide and the terminal 2 more reliable, and increases the safety of the double-sealed ceramic high-voltage DC contactor;

Furthermore, when the wire needs to be disassembled, the rotating pressure rod 413 can be manually turned to rotate, and then the compression nut 3 is rotated to keep the compression nut 3 away from the wire, and then one end of the rotation rod 408 will lose the pressure of the compression nut 3. At this time, under the influence of gravity, the counterweight sliding rod 402 slides downward, causing the rotating rod 408 to rotate, and at the same time drives the connecting rod 406 to rotate and pulls the arc clamp rod 407 away from the wire, and at the same time, the bottom of the pushing piece 410 loses the rotation of the rotating rod 408 Push and support, the pushing piece 410 and the movable block 409 slide down and reset, and then the limiting column 411 can be manually pushed toward the limiting rod 416 and snapped with it, returning to the initial state, thereby facilitating the next installation of the wire;

Please refer to Figure 1 to Figure 6 for the above working process.

The following is the working process of the shock-absorbing protection mechanism to protect the contactor body 1, reduce the impact force of the contactor body 1 from the outside, and improve the durability of the contactor body 1:

The contactor body 1 can be inserted into the inner cavity of the silicone pad 501, and then the silicone pad 501 and the contactor body 1 can be placed on the upper surface of the support base 502, and then the knob 511 can be turned to drive the worm 509 to rotate at the same time. When the worm 509 rotates, At the same time, the worm gear 507 is driven to rotate, so that the rotating disk 505 is driven to rotate simultaneously through the worm gear 507. When the rotating disk 505 rotates, the movable rod 506 can be pulled to rotate, and then under the action of the movable rod 506, the connecting sliding rods 504 are pulled to each other through the movable rod 506. Approach, thereby driving the sliding arc-shaped rods 503 to approach each other through the connecting slide rod 504, thereby clamping the silicone pad 501, and then completing the installation of the silicone pad 501 and the contactor body 1. After the clamping is completed, the push rod 512 can be pushed The push rod 512 drives the sliding magnetic ring 513 to approach the fixed magnetic ring 510, and then according to the principle of magnet attraction, the fixed magnetic ring 510 and the sliding magnetic ring 513 are attracted together to assist in fixing the knob 511, and when necessary, the fixed magnetic ring 510 and the sliding magnetic ring 513 are attracted together. When the contactor body 1 is disassembled and inspected, the push rod 512 can be pulled to make the sliding magnetic ring 513 separate from the fixed magnetic ring 510, and then the worm 509 is reversed to make the worm wheel 507 and the rotating disk 505 rotate in reverse, so that the movable rod 506 pushes the connecting sliding rod 504 to each other. away, so that the sliding arc rod 503 breaks away from the silicone pad 501. By simply turning the worm 509, the disassembly and installation of the contactor body 1 can be completed, making it more convenient for maintenance. At the same time, the worm 509 and the worm gear 507, when the sliding arc rod 503 is moved outward by an external force, the connecting slide rod 504 drives the movable rod 506 to pull the rotating disk 505 and the worm gear 507 to rotate, but because the worm 509 can only drive the worm gear 507 to rotate, the worm gear 507 cannot drive the worm. The principle of 509 rotation makes it impossible for the external force pulling the sliding arc rod 503 to interfere with it, thereby improving the fixing effect of the contactor body 1. After clamping the contactor body 1, the sliding magnetic ring 513 and the fixed The adsorption of the magnetic ring 510 increases the resistance when the knob 511 rotates, thereby preventing the knob 511 from rotating due to interference from external forces, thereby further improving the fixing effect when the sliding arc rod 503 is clamped, so that after the contactor body 1 is installed More stable during use;

Furthermore, when the contactor body 1 is impacted by an external force, through the arrangement of the silicone pad 501, because the silicone pad 501 is made of silicone, which is a highly elastic material, the contactor body 1 is impacted by the external force and transmitted to the silicone. When the pad 501 is put on, the silicone pad 501 will deform and quickly return to its original shape, absorb and disperse the impact force at the same time, and then dissipate the vibration energy, thereby reducing the impact force on the contactor body 1, protecting the contactor body 1, and increasing the contact The durability of the device body 1;

Please refer to Figure 7 to Figure 9 for the above working process.

Overview:

When the wire is installed, under the downward pressure clamping of the compression nut 3 and the clamping of its outer surface by the arc-shaped clamping rod 407, the fixing angle of the wire is increased, and at the same time, the wire is prevented from loosening when it is connected to the terminal 2 or loose phenomenon, avoid wire overlap and poor contact, improve the stability of the wires and terminals 2 when used, and at the same time make the upper end of the rotating pressure rod 413 rotate and press to the top of the compression nut 3, thereby rotating the pressure rod 413 Under the downward pressure, the resistance of the compression nut 3 when moving upward is increased, making the fixing effect between the guide and the terminal 2 more reliable, increasing the safety when using the double-sealed ceramic high-voltage DC contactor, and then, by The silicone pad 501 is set when the contactor body 1 is impacted by an external force and transmitted to the silicone pad 501. The silicone pad 501 will deform and quickly return to its original shape, while absorbing and dispersing the impact force, and then dissipating the vibration energy, thereby reducing the contactor The impact force received by the body 1 protects the contactor body 1 and increases the durability of the contactor body 1 .
