Abstract
Description
Technical Field
[0001] This utility model is an anti-loosening elastic contact terminal structure, belonging to the field of terminal structure technology. Background Technology
[0002] Terminal structures are key components used for electrical connections and are widely used in various electronic devices and electrical systems. They mainly consist of a metal conductor and an insulating shell. The metal conductor is responsible for conducting current, and its material is often a copper alloy with good conductivity. Through special processing, it possesses excellent corrosion resistance and conductivity stability. The insulating shell isolates the conductor from the external environment, ensuring electrical safety, and is usually made of plastic with good insulation properties.
[0003] Common terminal structures typically employ rigid connections, which are prone to loosening over prolonged use. This can lead to inconsistent electrical contact, potentially causing poor contact and affecting the normal operation of the terminals. Therefore, we propose an anti-loosening elastic contact terminal structure. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Please see Figures 1-6 This utility model provides a technical solution: an anti-loosening elastic contact terminal structure, including terminal 1, and further including:
[0027] Terminal 2 is located at one end of terminal 1. A slot 3 is provided at one end of terminal 2. A plug block 4 is fixedly installed at one end of terminal 1. Two limiting grooves 5 are provided on the periphery of plug block 4. Two limiting strips 6 are fixedly installed on the inner wall of slot 3. Several sliding grooves 8 are provided inside terminal 2 and on the periphery of slot 3. Sliding rods 9 are slidably installed in several sliding grooves 8. One end of several sliding rods 9 passes through the sliding grooves 8 and is fixedly installed with the same extrusion plate 11. A rubber pad 2 12 is fixedly installed on one side of extrusion plate 11. A rubber pad 7 is fixedly installed at one end of terminal 1 and on the periphery of plug block 4. A spring 10 fixed to the inner wall of sliding groove 8 is fixedly installed at the other end of sliding rod 9.
[0028] A limiting component is located within terminal 2 and is used to limit the insertion block 4.
[0029] In use, the operator inserts the plug 4 at one end of terminal 1 into the slot 3. Simultaneously, two limiting strips 6 on the inner wall of slot 3 enter two limiting grooves 5, thus limiting the plug 4 and preventing it from rotating. At this time, rubber pad 7 compresses rubber pad 12 and the compression plate 11, causing them to move. The movement of the compression plate 11 drives several sliding rods 9 to move, which in turn compress several springs 10, causing them to contract until the plug 4 is fully inserted into slot 3. At this point, the limiting assembly can... The insertion block 4 is limited to achieve an elastic connection between terminal 1 and terminal 2. At the same time, under the rebound force of several springs 10, several springs 10 will squeeze several sliding rods 9, and several sliding rods 9 will squeeze the compression plate 11, so that the rubber pad 12 on the compression plate 11 is tightly attached to the rubber pad 7. At the same time, both rubber pad 7 and rubber pad 12 will undergo slight deformation, so that the connection between terminal 1 and terminal 2 can be more stable, ensuring that the connection between terminal 1 and terminal 2 will not be loose.
[0030] In this embodiment, the limiting component includes:
[0031] The slide 13 is located inside the terminal 2 and above the slot 3. A limiting block 14 is slidably installed inside the slide 13. The bottom end of the limiting block 14 passes through the bottom of the slide 13 and extends into the slot 3. A pull rod 15 is fixedly installed at the top of the limiting block 14 and inside the slide 13. The top end of the pull rod 15 passes through the top of the slide 13 and extends to the outside. A spring 16 is sleeved on the pull rod 15 and inside the slide 13. A limiting hole 17 is opened at the top of the plug 4.
[0032] One end of the insert 4 will press the bottom end of the limiting block 14, causing the limiting block 14 to move upward. The upward movement of the limiting block 14 will compress the second spring 16 to retract until the insert 4 is fully inserted into the slot 3. At this time, under the action of the rebound force of the second spring 16, the second spring 16 will press the limiting block 14 to move downward until the bottom end of the limiting block 14 is inserted into the limiting hole 17. At this time, the limiting block 14 can limit the insert 4, thereby realizing the elastic connection between terminal 1 and terminal 2.
[0033] In this embodiment, the bottom end of the limiting block 14 is inserted into the limiting hole 17, the bottom end of the limiting block 14 has an inclined structure, the pull rod 15 is slidably connected to the slide groove 13 and the terminal 2, and the two ends of the spring 16 are tightly welded to the top of the limiting block 14 and the slide groove 13 respectively.
[0034] Specifically, it ensures that the bottom end of the limiting block 14 can be inserted into the limiting hole 17, that one end of the insert block 4 can press the limiting block 14 to move, that the pull rod 15 can slide normally in the slide groove 13 and the terminal 2, and that the structure of the spring 16 is stable.
[0035] In this embodiment, the insert 4 is inserted into the slot 3, and the limiting strip 6 is inserted into the limiting groove 5.
[0036] Specifically, this ensures that the insert 4 can be inserted into the slot 3 and that the limiting strip 6 can be inserted into the limiting groove 5.
[0037] In this embodiment, several sliding rods 9 are distributed in a ring with equal spacing.
[0038] Among these measures, the structural stability of several sliding rods 9 is ensured.
[0039] In this embodiment, one end of the sliding rod 9 is slidably connected to terminal 2.
[0040] Specifically, it is ensured that one end of the sliding rod 9 can slide normally within terminal 2.
[0041] In this embodiment, the plug 4 and the terminal 1 are integrally formed.
[0042] Among these measures, it is essential to ensure the structural stability of plug 4 and terminal 1.
[0043] Working principle: During use, the operator inserts the plug 4 at one end of terminal 1 into the slot 3. Simultaneously, the two limiting strips 6 on the inner wall of the slot 3 enter the two limiting grooves 5, thus limiting the plug 4 and preventing it from rotating. At this time, the rubber pad 7 will press the rubber pad 12 and the pressing plate 11 to move. The movement of the pressing plate 11 drives several sliding rods 9 to move, and the movement of the sliding rods 9 will press several springs 10 to retract. At the same time, one end of the plug 4 will press the bottom end of the limiting block 14, causing the limiting block 14 to move upward. The upward movement of the limiting block 14 will press the spring 16 to retract until the plug 4 is fully inserted into the slot 3. At this time, the spring 16... Under the action of the rebound force, spring 16 will press the limiting block 14 downward until the bottom end of the limiting block 14 is inserted into the limiting hole 17. At this time, the limiting block 14 can limit the insertion block 4, thereby realizing the elastic connection between terminal 1 and terminal 2. At the same time, under the action of the rebound force of several springs 10, several springs 10 will press several sliding rods 9, and several sliding rods 9 will press the pressing plate 11, so that the rubber pad 12 on the pressing plate 11 is tightly attached to the rubber pad 7. At the same time, both rubber pad 7 and rubber pad 12 will undergo slight deformation, so that the connection between terminal 1 and terminal 2 can be more stable, ensuring that the connection between terminal 1 and terminal 2 will not be loose.
