Description

Technical Field

[0001] This utility model relates to the field of battery terminal technology, specifically a new energy lithium battery terminal. Background Technology

[0002] Currently, new energy lithium battery terminals typically consist of an insulating base, a metal terminal extending out of the insulating base, a sealing gasket inside the insulating base, and a dust cap on the metal terminal. During use, screws are simply passed through the screw holes in the insulating base for installation. However, because the insulating base is made of plastic, excessive screw tightening can easily cause it to crack. Furthermore, the current dust caps, which are directly fitted onto the metal terminal, have very little friction, making them prone to slipping and instability. Additionally, the dust caps lack positive and negative markings, easily causing confusion during connection. Therefore, we propose a new type of new energy lithium battery terminal. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a new energy lithium battery terminal block, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a new energy lithium battery terminal block, including a mounting base, on which a metal terminal block is mounted, the metal terminal block having a knurled groove, a dust cap being fitted onto the metal terminal block, the metal terminal block and the dust cap being adapted to each other, the dust cap having positive and negative markings, and a metal ring being provided on the mounting base.

[0005] Preferably, the number of metal rings is four and they are symmetrically distributed around the center of the mounting base, and the metal rings are threaded inside.

[0006] Preferably, a reinforcing ring is provided on the surface of the metal terminal block and above the mounting base, and a reinforcing rib is provided on the outer side of the reinforcing ring.

[0007] Preferably, the inner cavity of the mounting base is provided with a rubber pad, the rubber pad is sleeved onto the surface of the metal terminal, and the rubber pad has a through hole that corresponds to the position of the inner cavity of the metal ring.

[0008] Preferably, the inner wall of the dust cap is in contact with the surface of the metal terminal block.

[0009] Preferably, the mounting base, metal ring, metal terminal, reinforcing ring, and reinforcing rib are integrally formed.

[0010] This utility model provides a new energy lithium battery terminal, which has the following beneficial effects:

[0011] 1. This new energy lithium battery terminal has knurled grooves added to the metal terminal. The knurled grooves contact the inner wall of the dust cap, thereby increasing the friction between the metal terminal and the dust cap, preventing the dust cap from falling off, and improving stability.

[0012] 2. This new energy lithium battery terminal features a metal ring added to the mounting base. The metal ring is used to secure the screw, increasing the screw's torque and preventing direct contact between the screw and the mounting base, thus preventing cracking of the mounting base due to the screw's force. Positive and negative markings are added to the dust cap. When the metal terminal is negative, the marking on the dust cap is negative; similarly, when it is positive, the marking on the dust cap is positive. The metal terminal and dust cap are perfectly matched. If they are mismatched, the dust cap and metal terminal will not make proper contact, causing the dust cap to detach or be improperly installed. This allows the operator to easily identify the correct terminal and effectively avoids confusion during on-site installation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a new energy lithium battery terminal block, including a mounting base 1, on which a metal terminal block 6 is mounted. The metal terminal block 6 is a negative metal terminal block, and a knurled groove 5 is provided on the metal terminal block 6. By adding the knurled groove 5 to the metal terminal block 6, the knurled groove 5 contacts the inner wall of the dust cap 7, thereby increasing the friction between the metal terminal block 6 and the dust cap 7, preventing the dust cap 7 from falling off, and improving stability.

[0029] A dust cap 7 is fitted onto the metal terminal 6. The dust cap 7 is a negative dust cap and has a negative marking. By adding positive and negative markings to the dust cap 7, when the metal terminal 6 is a negative metal terminal, the marking on the dust cap 7 will be the negative marking. The specifications of the metal terminal 6 and the dust cap 7 are compatible. When the two are used together, if they are not compatible, the dust cap 7 will not be able to make proper contact with the surface of the metal terminal 6, and the dust cap 7 will fall off directly or be improperly installed. This allows the operator to know the situation and effectively avoids confusion during on-site installation.

[0030] Mounting base 1 is provided with a metal ring 4. By adding a metal ring 4 to mounting base 1, the screw is installed using the metal ring 4, which increases the torque value of the mounting screw, avoids direct contact between the mounting screw and mounting base 1, and prevents mounting base 1 from cracking under the action of the screw.

[0031] There are four metal rings 4, which are symmetrically distributed around the center of the mounting base 1. The metal rings 4 have internal threads.

[0032] A reinforcing ring 2 is provided on the surface of the metal terminal 6 and above the mounting base 1, and a reinforcing rib 3 is provided on the outside of the reinforcing ring 2.

[0033] The inner cavity of the mounting base 1 is provided with a rubber pad 9, which is sleeved onto the surface of the metal terminal 6. The rubber pad 9 has a through hole 8, and the through hole 8 corresponds to the position of the inner cavity of the metal ring 4.

[0034] The inner wall of the dust cap 7 is in contact with the surface of the metal terminal 6.

[0035] The metal ring 4 and the metal terminal 6 are placed in the plastic mold of the mounting base 1. The mounting base 1, the reinforcing ring 2 and the reinforcing rib 3 are formed by injection molding, thereby forming an integral structure of the mounting base 1, the metal ring 4, the metal terminal 6, the reinforcing ring 2 and the reinforcing rib 3. The reinforcing ring 2 restricts the position of the dust cap 7, and the reinforcing rib 3 enhances the stability of the connection between the metal terminal 6 and the mounting base 1.

[0036] Example 2

[0037] Based on Example 1, please refer to Figures 5 to 8 Unlike Embodiment 1, the metal terminal 6 is a positive metal terminal, and a dust cap 7 is fitted onto the metal terminal 6. The dust cap 7 is a positive dust cap and has a positive marking. When the metal terminal 6 is a positive metal terminal, the marking on the dust cap 7 is a positive marking.

[0038] Example 3

[0039] Based on Example 1, please refer to Figures 9 to 12 Unlike Embodiment 1, the bottom shape of the metal terminal 6 is different; it is flat.

[0040] In summary, this new energy lithium battery terminal first places the metal terminal 6 and four metal rings 4 in a plastic mold, and then uses injection molding to integrally form the mounting base 1, the metal terminal 6 and the metal rings 4. Then, the rubber pad 9 is inserted into the inner cavity of the mounting base 1 from the bottom. The through holes 8 on the rubber pad 9 correspond one-to-one with the inner cavity of the metal ring 4. Screws are used to fix the metal ring 4 and the inner cavity of the rubber pad 9. Finally, the matching dust cap 7 is put on to complete the assembly.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
