Electrical Connector Diagonal Insertion Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors face issues such as limited alignment flexibility, terminal wear, resistance during connection and disconnection, and inability to simultaneously insert positive and negative terminals, leading to potential damage and sparks.
Innovation Solution
The design features a first connecting member with a cylindrical socket and a second connecting member that can be diagonally aligned, utilizing guiding grooves and blades to reduce resistance, prevent terminal wear, and facilitate simultaneous terminal insertion, along with drainage and vent channels for heat and water management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the male connector and female connector are connected straightly, then the connection is simple, but the connecting surface is prone to wear when the connectors are not aligned
Solution Approach 1:
The patent introduces a diagonal connection dimension by forming receiving slots and blades at specific angles (e.g., 45 degrees) relative to the connector axis. This diagonal arrangement allows connectors to align and connect along a diagonal path rather than strictly straight, reducing wear on the connecting surface while maintaining connection simplicity.
2Productivity
If the power terminals and signal terminals are connected simultaneously, then the connection speed is fast, but sparks may damage electronic components
Solution Approach 1:
The patent segments the terminals into different groups (power terminals and signal terminals) with different insertion depths. Power terminals extend further than signal terminals, causing them to connect and disconnect at different times. This segmentation enables sequential connection that prevents simultaneous contact of all terminals, eliminating sparks while maintaining fast connection speed.
Solution Approach 2:
The patent implements preliminary action by designing the power terminals to make contact first during insertion, establishing a safe electrical connection before signal terminals engage. This preliminary sequencing of terminal contact prevents harmful sparks while maintaining efficient connection.
3Productivity
If the connectors are disconnected quickly, then the operation is efficient, but resistance is generated when air cannot be discharged
Solution Approach 1:
The patent extracts the air discharge function by providing dedicated vent channels that are separate from the electrical terminal connections. These vent channels allow air to be discharged during connector insertion and removal, eliminating resistance and vacuum suction effects while maintaining efficient disconnection operation.
4Reliability
If the connectors require precise alignment, then the connection is stable, but the alignment flexibility is limited
Solution Approach 1:
The patent employs asymmetric guiding structures including guiding grooves and guiding pieces with specific directional orientations. These asymmetric features provide alignment guidance while allowing flexibility in the approach direction, enabling connectors to be aligned diagonally or at various angles while maintaining stable connection. The asymmetric design increases adaptability without sacrificing connection reliability.
