A locking structure for preventing loosening of AC connectors

Abstract

This utility model discloses an anti-loosening AC connector locking structure, belonging to the technical field of locking structures. It includes a socket connector, one end of which is fixedly connected to an AC connector socket, and an AC connector plug is inserted into the AC connector socket. This utility model, by setting a positioning locking strip and a positioning locking groove, provides precise axial positioning guidance during connection, ensuring coaxial docking of the plug and socket. Simultaneously, the second tangential groove on the surface of the positioning locking strip provides a mechanical engagement point for the locking block, forming a stable force-bearing support surface to resist radial vibration. As the plug penetrates deeper, the locking block embeds into the second tangential groove under the action of a spring, utilizing friction and spring force to form a bidirectional locking force, resisting axial separation and ensuring connection stability. Furthermore, during unlocking, the limiting block can drive the locking block to precisely exit, reducing frictional wear.

Description

Technical Field

[0001] This utility model belongs to the field of locking structure technology, specifically relating to a locking structure for an anti-loosening AC connector. Background Technology

[0002] Locking structures are devices or structures that restrict the relative movement between components, ensuring they remain fixed under specific operating conditions and preventing positional changes or loosening due to external forces, vibrations, or other factors. The locking structure of an AC connector is designed to ensure a secure connection between the plug and the socket.

[0003] Existing AC connectors are prone to loosening and separation under conditions such as vehicle bumps and equipment vibrations, leading to poor contact and power outages, which in turn affect the stable transmission of power. Therefore, a locking structure for preventing loosening of AC connectors is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a locking structure for an anti-loosening AC connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a locking structure for an anti-loosening AC connector, comprising a socket connector, one end of which is fixedly connected to an AC connector socket, an AC connector plug being inserted into the AC connector socket, one end of which is fixedly connected to an assembly, one end of which is fixedly connected to a positioning ring, the other end of which is fixedly connected to a plug connector, and two positioning locking strips fixedly connected to the surface of the positioning ring, each of the two positioning locking strips having a first tangential groove on its surface. The socket connector has a second tangential groove, and two positioning locking grooves are provided inside the socket connector. Locking blocks are inserted and connected to the inner walls of the two second tangential grooves respectively. The socket connector has two limiting grooves, and limiting combination blocks are slidably connected to the inner walls of the two limiting grooves respectively. Springs are fixedly connected to the other ends of the two limiting combination blocks respectively. The socket connector has two pull-out sliding grooves, and pull-out sliding rods are inserted and connected to the inner walls of the two pull-out sliding grooves respectively. Operating handles are fixedly connected to the other ends of the two pull-out sliding rods respectively. Two protective rings are fixedly connected to the surface of the socket connector.

[0006] By setting up the above structure, during connection, the insertion and cooperation of the positioning lock bar and the positioning lock groove can provide precise axial positioning guidance, ensuring that the plug and socket are coaxially connected. At the same time, the second phase groove on the surface of the positioning lock bar can provide a mechanical engagement point for the lock block, forming a stable force-bearing support surface to resist radial vibration. As the plug is inserted, the lock block is embedded into the second phase groove under the action of spring thrust. The friction force and spring force form a bidirectional locking force to resist axial separation and ensure connection stability. When unlocking, the limit block can drive the lock block to exit precisely, reducing friction loss. The limit block and spring are linked. In the locked state, the spring thrust presses the second phase groove to compensate for vibration gap. When unlocking, the spring is compressed to store potential energy. After the release operation, the spring resets and drives the lock block to return to its position automatically. With the coordinated action of all components, a full-process anti-loosening function can be realized from precise positioning and automatic locking to convenient unlocking, ensuring connection reliability.

[0007] As a preferred embodiment, the positioning ring is located outside the AC connector plug.

[0008] As a preferred embodiment, the two positioning lock bars are respectively inserted and connected to the positioning lock slots.

[0009] As a preferred embodiment, the two limiting grooves are respectively connected to the positioning lock groove.

[0010] As a preferred embodiment, one end of each of the two limiting blocks is fixedly connected to one end of the locking block.

[0011] As a preferred embodiment, the two pull-out grooves are respectively connected to the limiting groove.

[0012] As a preferred embodiment, one end of each of the two pull-out slide rods is fixedly connected to the other end of the limiting assembly block, and the two pull-out slide rods are respectively inserted and connected to the protective ring.

[0013] By setting a protective ring, which is fitted on the outside of the pull-out slide bar, impurities can be prevented from entering the pull-out slide groove and causing jamming. At the same time, it provides radial support for the pull-out slide bar, improving unlocking stability and structural impact resistance.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting a positioning locking bar and a positioning locking groove, provides precise axial positioning guidance during connection by fitting the positioning locking bar and the positioning locking groove together, ensuring coaxial docking of the plug and socket. Simultaneously, the second tangential groove on the surface of the positioning locking bar provides a mechanical engagement point for the locking block, forming a stable force-bearing support surface to resist radial vibration. As the plug is inserted, the locking block embeds into the second tangential groove under the action of spring force, utilizing friction and spring force to form a bidirectional locking force, resisting axial separation and ensuring connection stability. Furthermore, during unlocking, the limiting assembly block can precisely withdraw the locking block, reducing frictional loss. The limiting assembly block and spring work together; in the locked state, the spring force presses against the second tangential groove to compensate for vibration gaps. During unlocking, the compressed spring stores potential energy, and the release operation resets the spring, causing the locking block to automatically return to its position. With the coordinated action of all components, a full-process anti-loosening function is achieved from precise positioning and automatic locking to convenient unlocking, ensuring connection reliability.

[0016] This invention, by setting a protective ring, which is sleeved on the outside of the pull-out slide rod, can prevent impurities from entering the pull-out slide groove and causing jamming. At the same time, it provides radial support for the pull-out slide rod, improving unlocking stability and structural impact resistance. Attached Figure Description

Locking blocks 11 are inserted into the inner walls of the two second tangential grooves 9. Two limiting grooves 12 are formed inside the socket connector 1. Limiting combination blocks 13 are slidably connected to the inner walls of the two limiting grooves 12. Springs 14 are fixedly connected to the other ends of the two limiting combination blocks 13. Two pull-out sliding grooves 15 are formed inside the socket connector 1. Pull-out sliding rods 16 are inserted into the inner walls of the two pull-out sliding grooves 15. The other ends of the two pull-out sliding rods 16 are... An operating handle 17 is fixedly connected to the socket connector 1. Two protective rings 18 are fixedly connected to the surface of the socket connector 1. By setting a positioning locking strip 7 and a positioning locking groove 10, the insertion and cooperation of the positioning locking strip 7 and the positioning locking groove 10 during connection can provide precise axial positioning guidance, ensuring that the plug and socket are coaxially connected. At the same time, the second tangential groove 9 on the surface of the positioning locking strip 7 can provide a mechanical engagement point for the locking block 11, forming a stable force-bearing support surface to resist radial vibration. As the plug is inserted, the locking block 11 is inserted into the second tangential groove 9 under the pushing force of the spring 14, utilizing friction and the spring 14. The force forms a bidirectional locking force to resist axial separation and ensure connection stability. When unlocking, the limit block 13 can drive the locking block 11 to exit precisely, reducing frictional loss. The limit block 13 is linked with the spring 14. In the locked state, the spring 14 pushes and presses the second tangential groove 9 to compensate for vibration gap. When unlocking, the spring 14 is compressed to store potential energy. After the release operation 17, the spring 14 resets and drives the locking block 11 to return to its position automatically. With the coordinated action of each component, the entire process of anti-loosening function from precise positioning and automatic locking to convenient unlocking can be realized, ensuring connection reliability.

[0025] The positioning ring 5 is located outside the AC connection plug 3.

[0026] Two positioning lock bars 7 are respectively inserted and connected to the positioning lock grooves 10.

[0027] The two limiting grooves 12 are respectively connected to the positioning lock grooves 10.

[0028] One end of each of the two limit combination blocks 13 is fixedly connected to one end of the locking block 11.

[0029] The two pull-out grooves 15 are respectively connected to the limiting grooves 12.

[0030] One end of each of the two pull-out slide rods 16 is fixedly connected to the other end of the limiting assembly block 13. Each of the two pull-out slide rods 16 is inserted and connected to a protective ring 18. By setting the protective ring 18, which is sleeved on the outside of the pull-out slide rod 16, impurities can be prevented from entering the pull-out slide groove 15 and causing jamming. At the same time, it provides radial support for the pull-out slide rod 16, improving unlocking stability and structural impact resistance.

[0031] Working principle and usage process of this utility model:

[0032] When performing the connection operation, the AC connection plug 3 is inserted into the AC connection socket 2. At this time, the positioning locking strip 7 on the positioning ring 5 is inserted into the positioning locking groove 10 of the socket connector 1. As the plug goes deeper, the locking block 11 will be embedded in the second tangential groove 9 of the positioning locking strip 7 under the action of the spring 14, so as to achieve automatic locking, ensure the stability of the connection, and at the same time ensure stable power transmission.

[0033] When unlocking is required, pull the operating handle 17. The operating handle 17 moves the sliding rod 16, which in turn moves the limiting block 13 within the limiting groove 12 and compresses the spring 14. The limiting block 13 then moves the locking block 11 out of the second tangential groove 9, thus separating the AC connector plug 3 from the AC connector socket 2 and releasing the lock. The entire process, through the cooperation of components such as the spring 14, the locking block 11, and the positioning lock bar 7, conveniently and quickly realizes the anti-loosening locking and unlocking operation of the connector.
