Description

Technical Field

[0001] This utility model relates to the field of battery terminal technology, specifically a terminal structure suitable for long-life batteries. Background Technology

[0002] As a core component of energy storage and power supply, batteries are widely used in transportation (automobiles, ships), new energy storage, emergency power supply and other fields. The terminal is the only conductive interface between the battery and the external circuit, and its structural reliability directly determines the battery's service life and safety performance.

[0003] During use, lead-acid batteries experience a gradual buildup of acid inside, which impregnates the terminals and sealant. Furthermore, the conventional cylindrical terminal design with a smooth surface makes them prone to detaching from the sealant when subjected to external force, leading to acid leakage. This leakage at the terminals prevents the battery from meeting its expected lifespan and reduces its overall lifespan. Therefore, there is an urgent need in this field to improve the terminal structure for long-life batteries, thereby addressing the shortcomings of existing technologies. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a terminal structure suitable for long-life batteries, thereby improving the overall service life of the battery terminals.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a terminal structure suitable for long-life storage batteries, including terminal posts and a battery cover for mounting the terminal posts. The battery cover has several mounting openings with a diameter larger than that of the terminal posts. A fixing step is provided at the bottom of the mounting opening. A through countersunk hole is provided at the bottom of the fixing step, penetrating the battery cover. An elastic sealing ring is embedded in the through countersunk hole. The sealing ring is fitted onto the side of the terminal post. A locking ring for pressing the sealing ring is provided in the fixing step. Several first grooves are provided on the side of the terminal post.

[0006] Preferably, the mounting opening is filled with sealant.

[0007] Preferably, the inner sidewall of the mounting opening is provided with a plurality of second grooves.

[0008] Preferably, a sealing ring is embedded between the fixed step and the opposite side of the locking ring, the sealing ring being elastic, and the side of the locking ring being threadedly connected to the fixed step.

[0009] Preferably, the upper part of the locking ring has several vertical holes, and the side of the locking ring has several horizontal holes that communicate with the vertical holes.

[0010] Preferably, the first groove is located inside the mounting opening, the fixing step, and the through countersunk hole, and the inner diameter of the locking ring is larger than the outer diameter of the pole terminal post.

[0011] Preferably, a polygonal snap-fit ​​block is fixedly connected to the upper part of the locking ring, and the polygonal snap-fit ​​block is polygonal in shape.

[0012] To address the shortcomings of existing technologies, this utility model provides a terminal structure suitable for long-life batteries, overcoming the deficiencies of existing technologies. The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, a locking ring is set to press the sealing ring, thereby improving the sealing effect of the sealing ring. The sealing ring is elastic and can play a good buffering role. Then, the sealant is sealed in the installation port. The sealant combines with the side of the terminal post with the first groove, thereby improving the bonding effect between the terminal post and the sealant, reducing the possibility of the terminal post separating from the sealant, and thus improving the service life of the overall battery terminal post.

[0014] 2. In this utility model, by providing a number of second grooves on the inner sidewall of the mounting opening, the second grooves improve the bonding effect between the sealant and the battery cover.

[0015] 3. In this utility model, a number of vertical holes are provided on the upper part of the locking ring, and a number of horizontal holes communicating with the vertical holes are provided on the side of the locking ring. The first groove is located in the mounting port, the fixing step and the through countersunk hole. The inner diameter of the locking ring is larger than the outer diameter of the pole terminal post. When the sealant is injected, the sealant flows into the sealing ring through the vertical holes and the horizontal holes, which increases the stability of the locking ring.

[0027] The specific implementation method in this embodiment is as follows: A sensitive material is added to the ABS material of the battery cover 2 to increase the bonding strength with the epoxy resin. A relative proportion of tin is added to the cast terminal post 1 to reduce the internal resistance of the terminal post and decrease the heat generated during battery charging and discharging. Before use, a first groove 8 is machined on the side of the terminal post 1 using a machining method (to remove surface impurities and oxide layers) to ensure effective bonding between the terminal post 1 and the sealant. The terminal post 1 is connected through the countersunk hole 5. A sealing ring 6 is fitted onto the side of the terminal post 1 and located at the countersunk hole. Inside the head hole 5, the upper part of the sealing ring 6 extends into the fixed step 4, and the locking ring 7 is threaded into the fixed step 4. The locking ring 7 presses the sealing ring 6, improving the sealing effect of the sealing ring 6. The sealing ring 6 is elastic and can play a good buffering role.
