Connector Shielding Segmentation for Wire Routing Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face challenges with thermal interference between electric wires, which reduces the durability of the wires and limits the flexibility of their routing paths due to the need to bundle them and increase wire diameter.
Innovation Solution
A connector design featuring a conductive and elastic second shielding member that covers the electric wire connection part, along with a sub-shield body and binding member, to prevent thermal interference while allowing individual wire routing and maintaining wire elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric wires are tied up in a bundle, then thermal interference between wires is generated, but the diameter of the electric wire must be increased to avoid influence of thermal interference
Solution Approach 1:
The shielding structure is segmented into a main shield body covering the housing and sub-shield bodies covering individual electric wire connection parts. This segmentation allows each wire to be independently shielded and routed without being bundled together, preventing thermal interference while maintaining durability through individual protection.
2Reliability
If the diameter of the electric wire is increased, then influence of thermal interference is avoided, but the degree of freedom of routing path is further reduced
Solution Approach 1:
The shielding structure is segmented into a main shield body covering the housing and sub-shield bodies covering individual electric wire connection parts. This segmentation allows each wire to be independently shielded and routed without being bundled together, preventing thermal interference while maintaining durability through individual protection.
Solution Approach 2:
The sub-shield bodies are designed as flexible tubular structures that can accommodate individual wire routing paths. These flexible shielding elements protect each wire independently without requiring increased wire diameter, maintaining both durability and routing flexibility.
3Volume of stationary object
If electric wires are tied up in a bundle, then space is saved, but thermal interference is generated between the electric wires
Solution Approach 1:
The shielding structure is segmented into a main shield body covering the housing and sub-shield bodies covering individual electric wire connection parts. This segmentation allows each wire to be independently shielded and routed without being bundled together, preventing thermal interference while maintaining durability through individual protection.
Solution Approach 2:
The sub-shield bodies are nested within the main shield body structure, with each sub-shield covering individual connection parts while the main shield covers the entire housing. This nested arrangement provides comprehensive shielding without requiring external space, preventing thermal interference while maintaining compact design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively prevents thermal interference, maintains wire elasticity, and enhances the flexibility of electric wire routing paths without requiring bundled wires or increased diameters.
Implementation Method 1
a second shielding member having a tubular shape, electrical conductivity, and elasticity that covers, from the outside, an end part on an opening side of the sub-shield body together with the electric wire pulled out from the opening
Implementation Method 2
a second shielding member having a tubular shape, electrical conductivity, and elasticity that covers, from the outside, an end part on an opening side of the sub-shield body
Implementation Method 3
a binding member that is wound around the second shielding member and the end part on the opening side of the sub-shield body over the second shielding member to fix the second shielding member to the end part on the opening side of the sub-shield body
Implementation Method 4
The sub-shield body may include a locking body that projects from an outer peripheral surface of the end part on the opening side, and the binding member having an annular shape after winding is arranged to be opposed to an end face on the main shield body side of the locking body
