A high voltage switch contact structure

Abstract

This utility model discloses a high-voltage switch contact structure, including a triggering part and a conductive contact located at one end of the electrical contact part. Two ring blocks are symmetrically arranged on a pin in the triggering part, and the two ring blocks are connected to each other by a spring. One ring block on the pin abuts against one end of the conductive contact rod, and the end of the conductive contact rod makes conductive contact with the conductive contact through the movement of the pin. The advantages of this utility model are: by using an insulated push-pull rod to push and pull the push-pull connector using a lever principle, combined with the connection between the ring block connected to one end of the spring and the end of the conductive contact rod, effective and sufficient electrical contact between the end of the conductive contact rod on the pin and the conductive contact is ensured. Furthermore, the spring's contraction potential energy accelerates the pull-back speed of the insulated push-pull rod, achieving instantaneous and rapid separation between the triggering connection structures. This improves the efficiency and safety of the high-voltage switch's opening and closing operations, with faster opening and closing speeds and an extremely low arc occurrence rate.

Description

Technical Field

[0001] This utility model relates to the field of high-voltage switches, specifically a high-voltage switch contact structure. Background Technology

[0002] High-voltage switches are used to control high-voltage systems and are widely used in power systems, electronic equipment, and industrial production. Their main function is to switch or close circuits within the rated voltage range. Existing high-voltage switches suffer from high risk and low efficiency during manual operation, especially during opening and closing, which can easily cause arcing at the contact points, damaging the contact structure and affecting the stability of the contact guidance. Therefore, this paper proposes a new high-voltage switch contact structure to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a high-voltage switch contact structure to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a high-voltage switch contact structure, including a trigger part and a conductive contact located at one end of the electrical connection part. Two ring blocks are symmetrically arranged on the pin in the trigger part, and the two ring blocks are connected to each other by a spring. One ring block on the pin abuts against one end of the conductive contact rod, and one end of the conductive contact rod makes conductive contact with the conductive contact through the movement of the pin.

[0005] Preferably, the conductive contact has a guide hole in the middle, and the inside of the guide hole is insulated from one end of the ejector pin.

[0006] Preferably, the two ends of the conductive contact rod have the same structural shape, and the conductive contact rod portion passes through the push-pull connector.

[0007] Preferably, the other end of the ejector pin is rotatably mounted on one end of the push-pull connector.

[0008] Preferably, an insulating push-pull rod is rotatably connected to the other end of the push-pull connector.

[0009] Compared with the prior art, the advantages of this utility model are as follows: by using an insulated push-pull rod to push and pull the push-pull connector based on the lever principle, and combining the connection of the ring block connected to one end of the spring with the connection of one end of the conductive contact rod, it can not only ensure effective and sufficient electrical contact between the end of the conductive contact rod on the pin and the conductive contact, but also accelerate the pull-back speed of the insulated push-pull rod by using the spring contraction potential energy, so as to achieve the effect of instantaneous and rapid separation between the trigger connection structures, thereby improving the efficiency and safety of the high-voltage switch opening and closing operation, and the opening and closing speed is faster and the arc occurrence rate is extremely low.

[0018] Please see Figure 1-3As shown, a high-voltage switch contact structure includes a trigger part 1 and a conductive contact 21 located at one end of an electrical connection part 2. Two ring blocks 12 are symmetrically arranged on the pin 11 in the trigger part 1, and the two ring blocks 12 are connected to each other by a spring 13. One ring block 12 on the pin 11 abuts against one end of a conductive contact rod 3, and one end of the conductive contact rod 3 makes conductive contact with the conductive contact 21 through the movement of the pin 11.

[0019] The conductive contact 21 has a guide hole in the middle, and the inside of the guide hole is insulated from one end of the ejector pin 11. The other end of the ejector pin 11 is rotatably mounted on one end of the push-pull connector 5.

[0020] The conductive contact rod 3 has the same structural shape at both ends, and part of the conductive contact rod 3 passes through the push-pull connector 5.

[0021] An insulating push-pull rod 4 is rotatably connected to the other end of the push-pull connector 5.

[0022] Working principle: When the insulating push-pull rod 4 is in a state of being pushed or pulled, it pushes the pin 11 connected by the push-pull connector 5 forward or pulls it backward, causing one end of the conductive contact rod 3 on the pin 11 to be in contact or separated from the conductive contact 21, thereby realizing the opening and closing of the switch.

[0023] The difference compared to existing technologies is:

[0024] By using the lever principle, the push-pull connecting piece 5 is pushed and pulled by the insulated push-pull rod 4. Combined with the connection between the ring block 12 connected to one end of the spring 13 and the conductive contact rod 3, it can ensure effective and sufficient electrical contact between the end of the conductive contact rod 3 on the pin 11 and the conductive contact 21. At the same time, the contraction potential energy of the spring 13 can be used to accelerate the pull-back speed of the insulated push-pull rod 4, achieving the effect of instantaneous and rapid separation between the trigger connection structures. This improves the efficiency and safety of the high-voltage switch opening and closing operation, and the opening and closing speed is faster with an extremely low arc occurrence rate.
