Solution Overview
Problem
Conventional high-voltage fuse designs are cumbersome and bulky due to the need for additional packaging, which hinders miniaturization and increases assembly complexity, and result in higher connection resistance in high-voltage circuits.
Innovation Solution
A conductive connection structure with a U-shaped configuration that eliminates the need for a package plate by directly sealing openings, reducing assembly steps and space occupation, and features a direct insertion mechanism into mating terminals to minimize connection resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a package plate is added to seal the opening of the tube body, then the sealing performance is improved, but the device complexity and volume increase
Solution Approach 1:
The package plate is merged with the conductive connection portion to form an integrated structure. The conductive connection portion has a first contact segment that seals the opening and a second contact segment for electrical connection, eliminating the need for separate package plate assembly while maintaining both sealing and electrical connectivity functions
Solution Approach 2:
The conductive connection portion serves multiple functions simultaneously: it seals the tube body opening, provides electrical connection to the conductive fusing body, and extends to connect with external circuits. This multi-functional design replaces what would traditionally require separate components
2Reliability
If a package plate is added to seal the opening, then the sealing performance is improved, but the length of the fuse increases
Solution Approach 1:
The sealing function and electrical connection function are merged into a single conductive connection portion structure, eliminating the need for an additional package plate that would extend the overall length of the fuse
3Reliability
If the conductive connection portion passes through the package plate, then the electrical connection is achieved, but the assembling becomes cumbersome
Solution Approach 1:
The package plate and conductive connection portion are merged into a single integrated component. The conductive connection portion is formed as an extension of the package plate structure, allowing the electrical connection to be established without separate assembly steps of passing components through each other
4Reliability
If the conductive fusing body extends through the package plate, then the electrical connection is achieved, but the assembling becomes cumbersome
Solution Approach 1:
The package plate and conductive connection portion are integrated into one structure, eliminating the need for the conductive fusing body to pass through a separate package plate. The connection is simplified to mounting the conductive connection portion to the tube body opening

AI summary
The present invention provides a conductive connection structure, a multifunctional high-voltage connector and a battery product, the conductive connection structure comprises: a main body portion; and two conductive connection portions. The main body portion comprises: a tube body having openings; and a conductive fusing body. The conductive connection portion has: a first contact segment connected to the conductive fusing body and sealing a corresponding opening; a second contact segment; and a transitional connection segment. It is not necessary to additionally provide the package plate, thereby making the structure of the conductive connection structure simple and the volume of the conductive connection structure small, reducing the assembling steps, and improving the space utilization of the multifunctional high-voltage connector. When the upper cover and the pedestal are assembled, the second contact segment is directly inserted into the corresponding mating terminal, thereby further reducing the connection resistance in the high-voltage circuit.
