[0002] With the rapid development of modern technology, batteries, as an important energy storage device, are widely used in many fields such as automobiles, communications, and power. In these application scenarios, battery terminals, as key components connecting batteries to external circuits, directly affect the stability and reliability of the entire system.
[0003] Traditional terminals often use simple nut fastening methods. Because the copper core has a smooth surface and the lead-based shell is relatively soft, it is easy to deform under external torque, which weakens the bonding force between the copper core and the lead-based shell, leading to copper core stripping. Especially in vibration environments, the wires connected to the copper core by bolts and nuts may loosen, which will affect the current transmission efficiency and even cause circuit failure. To address this issue, a non-loosening battery terminal structure is proposed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an anti-loosening battery terminal structure, including a housing 1, which is a frame structure for installing a battery. A terminal 3 is provided at the top of the housing 1. The terminal 3 is a component that connects the internal electrodes of the battery to the external circuit. An anti-loosening component is provided at the top of the housing 1 and the terminal 3 to increase the stability of the connection of the terminal 3. The anti-loosening component includes a connecting block 22 that provides support and limit, a second baffle 21 fixedly connected to the middle of the front surface of the connecting block 22, and a first baffle 2 fixedly connected to the middle of the rear surface of the connecting block 22. The second baffle 21 protects and limits the cable connecting the terminal 3. The first baffle 2 is located outside the bolt and nut to limit them. Both the second baffle 21 and the first baffle 2 are U-shaped. The U-shape can provide more stable limiting and protection.
[0031] Furthermore, the top of the housing 1 is provided with slots 23 on both the left and right sides of the terminal 3, which are fitted with plastic clips 24 to limit the connection block 22. The bottom left and right ends of the connection block 22 are fixedly connected with plastic clips 24 that fit into the slots 23 to quickly limit the connection block 22. The plastic clips 24 are L-shaped and the bottom end is beveled. By setting it as beveled, it is easy to squeeze the beveled surface of the plastic clips 24 to deform it and insert it into the slots 23. After the plastic clips 24 are elastically reset and locked into the inner wall of the slots 23, they can be quickly limited. The slots 23 are L-shaped to match the bottom of the plastic clips 24. The vertical slot of the slots 23 is twice the length of the vertical part of the plastic clips 24. When the plastic clips 24 are deformed by squeezing, they can slide out from the protruding part of the inner wall of the slots 23 for easy removal.
[0032] Reference Figure 2 , Figure 3 and Figure 4 The top of the connecting block 22 is provided with a limiting component, which includes a limiting block 4, which can limit the plastic block 24 to prevent it from deforming. The connecting block 22 has a groove 41 located on the right side of its center, providing space for the lever 43 and spring 42. The inner wall of the groove 41 is slidably connected to the lever 43, which drives the limiting block 44 to move. The limiting block 4 is designed in an inverted L shape with a T-shaped bottom. The L shape facilitates movement, while the T-shape limits the distance of movement. The limiting block 4 is designed as... On the left side surface of the plastic block 24, the lever 43 is elastically connected to the connecting block 22 via the spring 42. One end of the spring 42 is fixedly connected to the left inner wall of the slide groove 41, and the other end of the spring 42 is fixedly connected to the left side of the lever 43. The elastic force of the spring 42 can quickly reset the limiting block 44. The bottom right side of the lever 43 is fixedly connected to the limiting block 44, which can be inserted into the second slot 46 to limit the limiting block 4. The top of the connecting block 22 is located on the right side of the slide groove 41 and has a second slot 45 that provides space for the limiting block 4 to move.
[0033] Furthermore, the limiting block 4 can only move vertically up and down. The limiting block 4 is slidably connected to the inner wall of the second slide groove 45. The upper and lower ends of the left side of the limiting block 4, away from the center, are provided with slots 46. The limiting block 44 can be inserted into the upper slot 46 to limit the limiting block 4 to the left side of the plastic block 24. When both sets of levers 43 are pressed at the same time, the limiting block 44 can be moved out of the upper slot 46. At this time, moving the limiting block 4 upward will make the T-shaped After the bottom end contacts the bottom end of the connecting block 22, it is limited. At this time, the second slot 46 below is aligned with the limiting block 44. The elastic force of the spring 42 can reset the limiting block 44 and limit the limiting block 4. At this time, the obstruction and limitation of the plastic block 24 can be released. The two plastic blocks 24 can be pressed quickly to remove the connecting block 22. The limiting block 44 is movably engaged in the inner wall of the second slot 46. There are two sets of limiting components, and the two sets of limiting components are symmetrically arranged with the center line of the connecting block 22 as the axis of symmetry.
[0034] Working principle: When installing the anti-loosening battery terminal 3 structure, first align the plastic clip 24 at the bottom of the connecting block 22 with the slot 23 at the top of the housing 1. Since the bottom of the plastic clip 24 is inclined, the plastic clip 24 deforms under the pressure of the connecting block 22 and smoothly inserts into the slot 23. After insertion, the plastic clip 24 returns to its original position due to its elasticity and is locked into the protruding inner wall at the bottom of the slot 23, thereby quickly limiting the connecting block 22 on the housing 1 and completing the initial fixation of the anti-loosening component to the housing 1. At this time, the baffle 21 and baffle 2 on the front and rear surfaces of the connecting block 22 protect and limit the connecting terminal 3 and the cable, preventing the cable from shaking randomly. The baffle 2 is U-shaped and fits on the outside of the bolt and nut, limiting them from the left and right sides, effectively preventing the bolt and nut from loosening due to vibration and other factors during use, thereby ensuring the stability of the connection between the terminal 3 and the external circuit.
[0035] In the initial state, the limiting block 4 is in the second slide groove 45, and its left side slot 46 engages with the limiting block 44. The limiting block 4 is located to the left of the plastic block 24, preventing the plastic block 24 from deforming and ensuring a tight fit between the plastic block 24 and the first slot 23, so that the connecting block 22 is firmly fixed to the housing 1. When it is necessary to remove the connecting block 22, press the two sets of levers 43 at the same time. The levers 43 slide in the first slide groove 41, compressing the spring 42 and causing the limiting block 44 to slide out of the second slot 46, thus releasing the limiting block 4. Then, move the limiting block 4 upwards until its bottom T-shaped part contacts the bottom of the connecting block 22 and stops moving. At this time, the lower slot 46 is aligned with the limiting block 44. Release the lever 43. Under the elastic force of the spring 42, the lever 43 returns to its original position, and the limiting block 44 is inserted into the lower slot 46, limiting the limiting block 4 to the position above the connecting block 22. At this time, the obstruction to the plastic block 24 is released. Then, the plastic block 24 can be squeezed again to deform it and slide out of the slot 23, thus removing the connecting block 22.
[0036] During equipment operation, even when subjected to external forces such as vibration, the baffle 1 2, baffle 2 21 and limit block 4 can effectively prevent the terminals 3, bolts, nuts and plastic blocks 24 from loosening or shifting due to the coordinated work of the anti-loosening components and the limit components. This ensures the stability of the connection between the battery and the external circuit, ensures that the current can be transmitted stably, and avoids circuit failures caused by loose connections.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
