Description

Technical Field

[0001] This utility model belongs to the field of AC connector technology, specifically relating to an AC connector for high anti-interference power distribution control equipment. Background Technology

[0002] An AC connector is a device that connects AC power to electrical equipment. It is mainly used to transmit high voltage and high current. The main function of an AC connector is to connect AC power to electrical equipment to ensure the stability and safety of power supply.

[0003] Existing AC connectors for high interference resistance power distribution control equipment form a power circuit by simply plugging in the plug and socket. However, this method suffers from insufficient mechanical connection strength and is prone to loosening due to vibration or external force, resulting in unstable connections. Therefore, a new AC connector for high interference resistance power distribution control equipment is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-interference-resistant AC connector for power distribution control equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an AC connector for high anti-interference power distribution control equipment, comprising a first connecting shell, a first insulating shell fixedly connected to one end of the first connecting shell, an anti-interference socket contact fixedly connected to one end of the first insulating shell, an anti-interference plug contact inserted inside the anti-interference socket contact, a threaded block fixedly connected to one end of the anti-interference plug contact, a second insulating shell fixedly connected to one end of the threaded block, a connecting bolt fixedly connected to one end of the second insulating shell, a second connecting shell fixedly connected to one end of the connecting bolt, a limiting groove formed inside the second insulating shell, a protective ring slidably connected to the inner wall of the limiting groove, a rotating ring fixedly connected to one end of the protective ring, and a threaded groove formed inside the anti-interference socket contact, with inner and outer threaded rings threadedly connected to the inner wall of the threaded groove.

[0006] By setting the above structure, the anti-interference socket contact and the anti-interference plug contact are inserted and cooperate to conduct the circuit and realize current transmission. Rotating the rotating ring can drive the inner and outer threaded rings to connect with the threaded groove and threaded block of the anti-interference socket contact respectively, so that the anti-interference plug contact and the anti-interference socket contact are tightly connected, enhancing the conductivity reliability and mechanical connection strength. At the same time, the protective ring can be moved out from the limiting groove of the second insulating shell, and together with the inner and outer threaded rings, it can cover the threaded block, the connection between the anti-interference socket contact and the anti-interference plug contact, preventing external collision damage and dust and foreign objects from entering, ensuring the stability and safety of the connection structure.

[0007] As a preferred embodiment, the protective ring slides on the surface of the threaded block.

[0008] As a preferred embodiment, the rotating ring rotates on the surface of the threaded block.

[0009] As a preferred embodiment, the internal and external threaded rings are threadedly connected to the anti-interference socket contact.

[0010] In one preferred embodiment, one end of the internal and external threaded rings is fixedly connected to one end of the rotating ring. In another preferred embodiment, the internal and external threaded rings are threadedly connected to a threaded block.

[0011] By setting a protective ring and a limiting groove, when the rotating ring drives the inner and outer threaded rings to rotate, the protective ring slides along the surface of the threaded block in the limiting groove. On the one hand, it provides limiting guidance for the axial movement of the rotating ring and the inner and outer threaded rings, ensuring that the threaded block, inner and outer threaded rings, and anti-interference socket contacts maintain coaxiality during the threaded connection process, avoiding offset or shaking. On the other hand, the protective ring always covers the connection area between the threaded block and the inner and outer threaded rings, preventing the intrusion of external foreign objects or collision damage, thereby improving the stability and reliability of the connector's mechanical connection.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by setting internal and external threaded rings and a protective ring, allows the anti-interference socket contact and the anti-interference plug contact to be inserted and cooperate to conduct the circuit and realize current transmission. Rotating the rotating ring can drive the internal and external threaded rings to be threadedly connected to the threaded groove and threaded block of the anti-interference socket contact, respectively, so that the anti-interference plug contact and the anti-interference socket contact are tightly connected, enhancing the conductivity reliability and mechanical connection strength. At the same time, the protective ring can be moved out from the limiting groove of the second insulating shell, and together with the internal and external threaded rings, it can cover the threaded block, the connection between the anti-interference socket contact and the anti-interference plug contact, preventing external collision damage and the intrusion of dust and foreign objects, ensuring the stability and safety of the connection structure.

[0014] This invention, by setting a protective ring and a limiting groove, allows the protective ring to slide along the surface of the threaded block within the limiting groove when the rotating ring drives the inner and outer threaded rings to rotate. On one hand, this provides limiting guidance for the axial movement of the rotating ring and the inner and outer threaded rings, ensuring that the threaded block, inner and outer threaded rings, and anti-interference socket contact maintain coaxiality during the threaded connection process, avoiding offset or shaking. On the other hand, the protective ring always covers the connection area between the threaded block and the inner and outer threaded rings, preventing the intrusion of external foreign objects or collision damage, thereby improving the stability and reliability of the connector's mechanical connection.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please refer to Figures 1-4. This utility model provides an AC connector for high anti-interference power distribution control equipment, including a first connecting shell 1. A first insulating shell 2 is fixedly connected to one end of the first connecting shell 1. An anti-interference socket contact 3 is fixedly connected to one end of the first insulating shell 2. An anti-interference plug contact 4 is inserted and connected inside the anti-interference plug contact 3. A threaded block 5 is fixedly connected to one end of the anti-interference plug contact 4. A second insulating shell 6 is fixedly connected to one end of the threaded block 5. A connecting bolt 7 is fixedly connected to one end of the second insulating shell 6. A second connecting shell 8 is fixedly connected to one end of the connecting bolt 7. A limiting groove 9 is formed inside the second insulating shell 6. A protective ring 10 is slidably connected to the inner wall of the limiting groove 9. A rotating ring 11 is fixedly connected to one end of the protective ring 10. A threaded groove 12 is formed inside the anti-interference socket contact 3. An inner and outer threaded ring 13 is threadedly connected to the inner wall of the threaded groove 12. By setting the inner and outer threaded ring 13 and the protective ring 10, the anti-interference socket contact 3 and the anti-interference plug contact 4 are connected. The insertion and connection of the conductive circuit enables current transmission. Rotating the rotating ring 11 can drive the inner and outer threaded rings 13 to connect with the threaded grooves 12 and threaded blocks 5 of the anti-interference socket contact 3 respectively, so that the anti-interference plug contact 4 and the anti-interference socket contact 3 are tightly connected, enhancing the conductivity reliability and mechanical connection strength. At the same time, the protective ring 10 can be moved out from the limiting groove 9 of the second insulating shell 6, and together with the inner and outer threaded rings 13, it can cover the connection between the threaded block 5, the anti-interference socket contact 3 and the anti-interference plug contact 4, preventing external collision damage and the intrusion of dust and foreign objects, and ensuring the stability and safety of the connection structure.

[0023] The protective ring 10 slides on the surface of the threaded block 5.

[0024] The rotating ring 11 rotates on the surface of the threaded block 5.

[0025] The internal and external threaded ring 13 is threadedly connected to the anti-interference socket contact 3.

[0026] One end of the internal and external threaded ring 13 is fixedly connected to one end of the rotating ring 11.

[0027] The internal and external threaded rings 13 are threadedly connected to the threaded block 5. By setting a protective ring 10 and a limiting groove 9, when the rotating ring 11 drives the internal and external threaded rings 13 to rotate, the protective ring 10 slides along the surface of the threaded block 5 in the limiting groove 9. On the one hand, it provides limiting guidance for the axial movement of the rotating ring 11 and the internal and external threaded rings 13, ensuring that the threaded block 5 and the internal and external threaded rings 13 and the anti-interference socket contact 3 maintain coaxiality during the threaded connection, avoiding offset or shaking. On the other hand, the protective ring 10 always covers the connection area between the threaded block 5 and the internal and external threaded rings 13, preventing the intrusion of external foreign objects or collision damage, thereby improving the stability and reliability of the connector's mechanical connection.

[0028] The working principle and usage process of this utility model are as follows: The anti-interference socket contact 3 and the anti-interference plug contact 4 are inserted and connected to conduct the circuit. Then, the rotating ring 11 is rotated, which drives the inner and outer threaded rings 13 to be threadedly connected to the anti-interference socket contact 3 and the threaded block 5 respectively. The inner and outer threaded rings 13 will be inserted into the anti-interference socket contact 3, so that the anti-interference socket contact 3 and the anti-interference plug contact 4 form a tight connection, which enhances the reliability of conductivity. At the same time, the protective ring 10 will move out from the inside of the second insulating shell 6 and always protect the internal threaded block 5, while isolating external interference.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
