Electrical Contact Arrangement Decoupling Electrical and Mechanical Lengths
Solution Overview
Problem
Existing electrical contact arrangements in telecommunications and data technology face challenges in achieving both good electrical transmission properties and sufficient resilience, as contacts need to be short to optimize transmission but long enough to compensate for tolerances and generate contact force.
Innovation Solution
The electrical contact arrangement decouples electrical and mechanical properties by having a shorter electrical contact length than mechanical contact length, allowing for a spring effect without compromising transmission properties, with the mechanical contact point secured through gluing, soldering, or clamping, and using a comb element for prestress, and a spring-elastic element for movement compensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact length is shortened to optimize electrical transmission properties, then the electrical transmission properties are improved, but the contact force and tolerance compensation capability deteriorate
Solution Approach 1:
The contact is segmented into two distinct functional zones: an electrical contact point zone with minimized length for optimal transmission properties, and a mechanical contact point zone with sufficient length for tolerance compensation and contact force generation. This segmentation allows each zone to be optimized independently for its specific function.
Solution Approach 2:
Different portions of the contact are given different lengths and mechanical properties tailored to their specific functions. The electrical contact point area has minimized length for best transmission, while the mechanical contact point area has sufficient length for spring effect and tolerance compensation. This local differentiation resolves the contradiction between transmission optimization and force generation.
2Stability of the object's composition
If the contact length is increased to compensate for tolerances and generate contact force, then the spring effect is improved, but the electrical transmission properties deteriorate
Solution Approach 1:
The contact structure is divided into separate electrical and mechanical contact point zones with different length characteristics. The mechanical contact point zone provides the necessary spring effect and tolerance compensation without affecting the minimized electrical contact path, thus maintaining transmission properties while achieving stability.
Solution Approach 2:
The mechanical contact point area is designed with sufficient length to provide spring effect and tolerance compensation, while the electrical contact point area maintains minimized length for optimal transmission. This local quality differentiation allows the contact to exhibit both stability and good transmission properties simultaneously.
3Adaptability or versatility
If the contact is designed to be resilient for tolerance compensation, then the tolerance compensation capability is improved, but the electrical transmission properties deteriorate due to increased contact length
Solution Approach 1:
The contact is segmented into distinct resilient mechanical portions and minimized electrical transmission portions. The resilient sections provide adaptability and tolerance compensation, while the electrical contact points maintain minimal length for optimal transmission properties, thus achieving both adaptability and reliability.
Solution Approach 2:
Different sections of the contact have different mechanical properties: the mechanical contact point sections have sufficient length and elasticity for resilience and adaptability, while the electrical contact point sections have minimized length for optimal transmission. This local quality variation resolves the contradiction between adaptability and transmission reliability.
