Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage connectors, in particular to an integrated high-voltage connector. Background Art

[0002] Battery technology is constantly improving to adapt to a variety of applications, from mobile devices to electric vehicles and renewable energy storage. Among them, the structure and design of batteries tend to be miniaturized and compact to increase energy density, reduce volume and weight, and reduce manufacturing costs. These trends require battery components to operate efficiently in limited space while requiring higher cost-effectiveness.

[0003] To adapt to this trend, a possible solution is to use an integrated high-voltage connector. An integrated high-voltage connector can connect the positive and negative electrodes of the battery in a single structure, reducing the required connection space, assembly complexity, and manufacturing costs. This design of connector helps to improve the integration of the battery system and further meet the requirements of miniaturization and compact layout.

[0004] However, most of the traditional connectors on the market currently use a connector structure with separate positive and negative poles, which leads to some defects and challenges: ① Inconvenient operation: The connector with separate positive and negative poles needs to be inserted and connected separately, which may be cumbersome during installation and maintenance, especially when operating in a limited space. ② High manufacturing cost: The cost of manufacturing separate connectors is relatively high because they usually require more parts and assembly processes. This puts pressure on the manufacturing cost of the entire battery system and reduces cost-effectiveness. ③ Consistency issues: Separate connectors may have problems with poor or unstable connection, which may affect the performance and reliability of the battery system.

[0017] After adopting the above structure, the utility model has the following advantages:

[0018] The utility model adopts an integrated connector to connect the positive and negative electrodes in a single structure. This design reduces the size of the connector, making it more suitable for miniaturized and compactly laid out battery systems. The advantage of reducing the size is that it can save valuable space and make the battery system more compact, which helps to use space resources more efficiently in various application fields.

[0019] Flexible Installation: The one-piece connector design is more flexible as it can adapt to different installation needs and conditions, which simplifies the installation process, especially when operating in limited space. This improves the installation efficiency of the battery system and reduces the risk of human error and installation problems.

[0020] Reduce costs: The use of integrated connectors is expected to reduce manufacturing costs. Fewer parts and assembly processes reduce manufacturing complexity, which helps save production, assembly, inspection, and installation costs, reduces the price of the final product, and improves market competitiveness.

[0021] Stronger consistency: The integrated connector helps improve the consistency of the connection and reduces the problem of poor or unstable connection. This means that the performance and reliability of the battery system are more stable and predictable, reducing the need for maintenance and troubleshooting. The enhanced consistency helps ensure that the battery system can always maintain a high level of performance in a variety of applications.

[0022] Prevent accidental touch: The one-piece connector design reduces the risk of accidental touch. Since the positive and negative poles are connected in one structure, the possibility of accidental touch or short circuit is reduced, which helps improve the safety of the battery system and reduces the risk of potential danger and damage.
