Elastic Center Contact Assembly for Stable Cable Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face challenges in achieving a stable electrical connection between a conducting wire and a center contact while facilitating easy insertion of a cable into the connector.
Innovation Solution
A cable assembly design featuring a center contact with a front and rear body, spaced apart from the conducting wire, and multiple contact arms that elastically deform to ensure a stable connection without interfering with cable insertion, allowing for simultaneous physical and electrical connection during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the center contact is designed to receive the conducting wire for stable electrical connection, then the electrical connection stability is improved, but the cable insertion difficulty increases
Solution Approach 1:
The contact arms are designed as elastic components that can dynamically deform during cable insertion. When the cable is inserted, the contact arms are pushed outward by the conducting wire and then elastically deform to contact and secure the wire, providing both easy insertion and stable connection without requiring precise alignment or forceful insertion.
2Reliability
If the contact arms are positioned to contact the conducting wire for stable connection, then the electrical connection stability is improved, but the cable insertion difficulty increases
Solution Approach 1:
The center contact is segmented into multiple independent contact arms that are distributed around the conducting wire. Each contact arm can independently deform and contact the wire, providing multiple contact points for stable electrical connection while maintaining a relatively simple overall structure that integrates seamlessly into the connector housing.
3Reliability
If the center contact structure is designed for stable wire reception, then the electrical connection stability is improved, but the assembly time increases
Solution Approach 1:
The contact arms are pre-positioned and pre-loaded in the holder structure before the conducting wire is inserted. This preliminary arrangement ensures that when the cable is inserted, the contact arms are already in the correct position to be pushed outward and make contact with the wire, eliminating the need for separate adjustment or alignment steps during assembly.
