Socket Connector Terminal Retention for Stable Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket connectors lack a limiting structure between the elastic terminal and the insulating body, leading to loosening and potential breakage of the elastic terminal due to frequent insertion and withdrawal, affecting signal transmission stability.
Innovation Solution
The socket connector design includes a shell with lateral walls featuring lug portions and limiting grooves, a lid with restricting grooves, and terminals with inserting tabs and limiting blocks, which are clipped and limited by these structures to stabilize the terminals within the insulating body, ensuring secure attachment and improved signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the elastic terminal is mounted in the insulating body without a limiting structure, then the assembly process is simple, but the elastic terminal is prone to loosening and breakage during frequent insertion and withdrawal operations
Solution Approach 1:
The insulating body is divided into functional regions including a limiting groove and a retaining groove. The limiting groove restricts the insertion depth of the elastic terminal, while the retaining groove holds the limiting structure of the terminal. This segmentation provides targeted constraints at different locations, preventing loosening and breakage while maintaining assembly simplicity.
Solution Approach 2:
A limiting structure is introduced as an intermediary element between the elastic terminal and the insulating body. This limiting structure includes a limiting portion that fits into the limiting groove and a retaining portion that fits into the retaining groove. The intermediary structure mediates the connection, providing reliable mechanical constraint without complicating the overall assembly process.
2Adaptability or versatility
If the elastic terminal is allowed to move freely in the insulating body, then the terminal can accommodate insertion forces, but the terminal becomes loose and affects signal transmission stability
Solution Approach 1:
The insulating body provides different types of constraints at different locations: the limiting groove provides depth restriction to prevent over-insertion, while the retaining groove provides lateral constraint to prevent loosening. This local differentiation of constraint qualities allows the terminal to accommodate forces while maintaining stable signal transmission.
