Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors in data center power supply units face challenges with complex terminal structures, high insertion forces, limited current carrying capacity, poor heat dissipation, and reduced versatility due to single connection plates at the rear end of each terminal.
Innovation Solution
The electrical connection module features a shell with rotatable terminals, multiple spring pieces for contact, and multiple connection members at the rear end, allowing simultaneous connection to multiple electrical components, enhancing current capacity and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multi-layer staggered overlapping terminals are adopted to improve current transmission capability, then the current transmission capability is improved, but the structure becomes complex and insertion force increases excessively
Solution Approach 1:
The terminal is divided into multiple terminal laminations (first terminal lamination, second terminal lamination, third terminal lamination) stacked in sequence. Each lamination is a separate component that can be independently manufactured and assembled, allowing the current transmission capability to be enhanced through stacking while maintaining manufacturing simplicity and controlling insertion force.
2Quantity of substance
If a single connection plate is used at the rear end of each terminal, then the structure is simple, but the current carrying capacity is poor and heat dissipation is insufficient
Solution Approach 1:
Multiple connection plates (first connection plate, second connection plate, third connection plate) are merged together at the rear end of the terminal, forming a integrated connection structure. This combining of multiple connection plates increases the current carrying capacity and provides enhanced heat dissipation surface area, solving both the current transmission and thermal management issues simultaneously.
3Device complexity
If a single connection plate is used at the rear end of each terminal, then the structure is simple, but the versatility is reduced
Solution Approach 1:
The connector is designed with multiple connection plates that can simultaneously connect to multiple electrical transmission components (such as multiple bus bars). This multi-functional design allows the connector to be universally applied in various configurations, enabling it to handle different current transmission scenarios and improving its adaptability across different applications.

AI summary
An electrical connection module includes a shell, a terminal, a first electrical connection member, and a second electrical connection member. The shell has a pair of side walls opposite each other in a transverse direction of the shell, a front opening and a rear opening opposite each other in a longitudinal direction of the shell, and a first spring piece and a second spring piece each formed on one side wall. The terminal has a rear end portion, is rotatably installed in the shell, and swings relative to the shell about an axis extending along a height direction of the shell. The first electrical connection member has a first plate-shaped part inserted into the rear opening and clamped between the first spring piece and one side of the rear end portion making electrical contact with the terminal. The second electrical connection member has a second plate-shaped part inserted into the rear opening and clamped between the second spring piece and the other side of the rear end portion making electrical contact with the terminal. A portion of the first electrical connection member and a portion of the second electrical connection member are located outside the shell and each electrically connect to one of a first electrical transmission component and a second electrical transmission component. A front end of the terminal extends out of the front opening and electrically contacts a mating terminal.
