Electrical Connector Terminal Geometry to Prevent Mating Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connectors often experience terminal deformation due to interference when assembled, as the fixed structural dimensions of terminals and housings lead to compression and friction during mating.
Innovation Solution
The design incorporates a terminal member with first and second terminals featuring bump and notch parts, which are complementary in shape, allowing for secure assembly without deformation by accommodating each other's geometry, and an anti-friction surface on the mating connector to prevent damage and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the terminal is assembled with the housing using fixed standard dimensions, then the structural stability is improved, but the terminal is prone to compression and deformation when mated with another electrical connector
Solution Approach 1:
The patent applies parameter changes by modifying the terminal structure from fixed standard dimensions to variable dimensions. The terminal includes an elastic piece with adjustable length that can be regulated between a first length when not subjected to external force and a second length when subjected to external force. This allows the terminal to adapt its dimensions during mating operations, preventing compression and deformation while maintaining structural stability through the elastic piece's inherent properties.
2Reliability
If the terminal of the electrical connector is inserted into the terminal of another electrical connector, then electrical connection is achieved, but the terminal is interfered with and compressed by the other terminal
Solution Approach 1:
The patent applies dynamics by transforming the terminal from a static fixed-dimension structure to a dynamic adjustable-dimension structure. The elastic piece can change its length based on external forces applied during mating. When the terminal is inserted into another connector, the elastic piece dynamically adjusts its length to accommodate the mating process, reducing compression forces while ensuring reliable electrical connection through the conductive structure.
3Manufacturing precision
If fixed standard size is used for housing and terminal, then manufacturing consistency is improved, but the terminal experiences friction and wear during assembly
Solution Approach 1:
The patent applies parameter changes by allowing the terminal's dimensional parameters to vary during assembly rather than maintaining fixed standard dimensions. The elastic piece's length can be regulated based on the assembly process requirements, which reduces friction and wear during insertion while still achieving consistent manufacturing results through controlled regulation of the elastic piece's dimensions.
