Description

Technical Field

[0001] This utility model belongs to the field of battery component technology, specifically, it relates to a positive electrode post cover plate. Background Technology

[0002] In the design and manufacturing system of batteries (including lithium-ion batteries, lead-acid batteries, and other chemical power sources), the positive electrode cap, as a key component of the battery's sealing structure and electrical connection system, plays a decisive role in the overall performance, safety, and lifespan of the battery. With the rapid development of industries such as new energy vehicles and large-scale energy storage power stations, the market has placed higher demands on the energy density, reliability, and cycle life of batteries.

[0003] Batteries are filled with electrolytes (such as organic electrolytes in lithium-ion batteries and sulfuric acid solutions in lead-acid batteries). These electrolytes are chemically reactive. If a leak occurs, it can not only corrode the external structure of the battery and cause short circuits, but it can also react with moisture and oxygen in the air, creating safety hazards (such as lithium-ion battery electrolyte leaks, which can easily cause combustion and explosion).

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the technical problem that batteries filled with electrolytes (such as organic electrolytes in lithium-ion batteries and sulfuric acid solutions in lead-acid batteries), which are chemically reactive and, if leaked, can not only corrode the external battery structure and cause short circuits, but may also react with moisture and oxygen in the air, creating safety hazards (such as lithium-ion battery electrolyte leaks easily leading to combustion and explosion), the basic concept of the technical solution adopted by this utility model is as follows: A positive electrode post cover plate includes a circular plate, a retaining ring is connected to the bottom end of the circular plate, a retaining groove is formed between the retaining ring and the circular plate, a sealing groove is formed on the inner wall of the retaining groove, and a sealing ring is installed on the inner wall of the sealing groove.

[0006] In a preferred embodiment of this utility model, a reinforcing block is provided at the bottom end of the circular plate and the outer wall of the retaining ring.

[0007] In a preferred embodiment of this utility model, the circular plate and the snap ring are made of metal, such as copper alloy, which has good electrical conductivity and a certain strength.

[0008] In a preferred embodiment of this utility model, the inner wall of the sealing groove is fitted to the outer wall of the sealing ring, the sealing ring is made of rubber, and the inner outer wall of the sealing ring protrudes from the inner wall of the sealing groove.

[0009] In a preferred embodiment of this utility model, there are several reinforcing blocks, which are evenly and equidistantly distributed on the cam ring and the circular plate.

[0010] Compared with the prior art, the present invention has the following advantages: This utility model uses a slot to insert into the outer wall of the positive electrode post for installation and connection. The sealing groove and sealing ring can improve the sealing between the overall cover plate and the positive electrode post, thereby preventing electrolyte leakage. At the same time, the sealing ring can improve the installation stability between the overall cover plate and the positive electrode post.

[0011] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0013] In the diagram: 1. Circular plate; 2. Snap ring; 3. Snap groove; 4. Sealing groove; 5. Sealing ring; 6. Reinforcing block. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0015] like Figures 1 to 3 As shown, a positive electrode post cover plate includes a circular plate 1, a retaining ring 2 connected to the bottom end of the circular plate 1, a retaining groove 3 between the retaining ring 2 and the circular plate 1, a sealing groove 4 on the inner wall of the retaining groove 3, and a sealing ring 5 installed on the inner wall of the sealing groove 4.

[0016] Furthermore, a reinforcing block 6 is provided at the bottom end of the circular plate 1 to connect with the outer wall of the retaining ring 2. The reinforcing block 6 can improve the connection stability between the circular plate 1 and the retaining ring 2, thereby improving the overall strength of the cover plate.

[0017] Furthermore, the circular plate 1 and the retaining ring 2 are made of metal, such as copper alloy, which has good electrical conductivity and a certain strength. This can further enhance the overall strength of the cover plate and improve its service life.

[0018] Furthermore, the inner wall of the sealing groove 4 fits snugly against the outer wall of the sealing ring 5. The sealing ring 5 is made of rubber, and the inner outer wall of the sealing ring 5 protrudes from the inner wall of the sealing groove 4. There are several reinforcing blocks 6, which are evenly and equidistantly distributed on the retaining ring 2 and the circular plate 1. By fitting snugly against the inner wall of the sealing groove 4 and the outer wall of the sealing ring 5, the sealing performance of the two together for the overall cover plate can be improved. By protruding the inner outer wall of the sealing ring 5 from the inner wall of the sealing groove 4, the inner outer wall of the sealing ring 5 can contact the positive electrode post and be squeezed against each other, thereby further improving the sealing performance of the cover plate.

[0019] The implementation principle of the positive terminal block cover in this embodiment is as follows: During use, the slot 3 between the retaining ring 2 and the circular plate 1 is aligned with the positive terminal block of the battery. The slot 3 is then inserted into the outer wall of the positive terminal block. During this process, the outer wall of the positive terminal block contacts and presses against the sealing ring 5, causing deformation. After the circular plate 1 and retaining ring 2 are placed on the positive terminal block, the rubber material of the sealing ring 5 allows for a tight fit between the outer wall of the sealing ring 5 and the outer wall of the positive terminal block through the elasticity of the rubber. Thus, the cooperation between the sealing slot 4 and the sealing ring 5 provides a good seal for the positive terminal block of the battery, preventing electrolyte leakage. Simultaneously, the rubber properties of the sealing ring 5 increase the connection friction with the positive terminal block, thereby improving installation stability. The reinforcing block 6 connected between the circular plate 1 and the retaining ring 2 increases the connection strength between them, thereby improving the ability to withstand mechanical stress during installation and maintenance.
