Shield Contact Spring With Support Spring For Cable Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield contact springs complicate the insertion of cables due to the contact spring's design, which often inhibits the insertion process and requires complex operation for users.
Innovation Solution
Incorporating a support spring that presses the contact spring out of the insertion region, allowing the contact spring to remain in an open state, simplifying the insertion process and enabling pre-tensioning for better contact, while maintaining a compact design and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact spring is designed to contact the cable shield, then electrical contact reliability is improved, but cable insertion becomes difficult due to the contact spring blocking the insertion region
Solution Approach 1:
The contact spring is designed to be movable between a retracted position (during cable insertion) and an engaged position (after insertion). The support spring enables this dynamic behavior by providing the force to move the contact spring out of the insertion region after the cable is inserted, ensuring reliable electrical contact without blocking the insertion process
2Ease of operation
If the contact spring is held in the open state during insertion, then cable insertion ease is improved, but additional components increase device complexity
Solution Approach 1:
The support spring and contact spring are combined into a single integrated component rather than separate parts. The support spring is formed as an extension of the contact spring, creating a unified structure that provides both the contact function and the support function, thereby reducing device complexity while maintaining ease of cable insertion
3Reliability
If the support spring projects into the space between contact spring and fixing spring, then support function is improved, but available space is reduced
Solution Approach 1:
The support spring projects locally into the space between the contact spring and fixing spring only at the specific location where support is needed, rather than extending throughout the entire assembly. This localized projection provides the necessary support function while minimizing the reduction of available space in other areas of the device
