Large Current Connector Guide Pillar Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Card Edge Connectors are too large due to the need for multiple power supply pins to carry high currents, which contradicts the miniaturization trend of electronic devices.
Innovation Solution
A large current transmission connector design featuring a pallet assembly and socket assembly with a locking structure, where the guide pillar acts as the male end and the locking structure as the female end, allowing for efficient current transmission without the need for extensive space allocation for power supply pins, utilizing a locking mechanism and optimized positioning and fixation elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple power supply pins are used to carry high current (50 A), then the current transmission capability is improved, but the connector volume increases
Solution Approach 1:
The guide pillar is designed to perform multiple functions simultaneously: it provides positioning guidance during insertion and also serves as the current transmission path. By merging the guidance function and current transmission function into a single structure, the connector achieves 50 A current capability without requiring separate power supply pins, thus reducing overall connector volume
Solution Approach 2:
The guide pillar transitions from a single-function positioning element to a multi-functional component that combines positioning, guidance, and electrical current transmission. This universal design allows the same structure to fulfill multiple roles, eliminating the need for additional dedicated power pins and reducing the number of components required

AI summary
The application discloses a large current transmission connector including the pallet assembly and the socket assembly. The pallet assembly includes the pallet and the guide pillar. The socket assembly includes a socket. The socket includes mounting holes and pins. The locking structure is arranged in the mounting hole. The locking structure is used for fixing the guide pillar on the socket and for conveying a current between the pallet assembly and the socket assembly. When the guide pillar and the locking structure are fixed together, the two guide pillars not only play the role of guiding, but also can carry the large current of 50 A. Thus, this connector does not need to set aside a lot of space for mounting the power supply pins. The space of the connector is saved effectively. The miniaturization trend of the connector is met.
