Sheet-like Shield for Wiring Harness Short Wire Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shield connectors cannot be crimped together when devices are closely connected, as the crimping operation interferes, preventing effective shielding between devices with short connecting wires.
Innovation Solution
A wiring harness using a sheet-like shield made of electrically conductive metal cloth is mounted to cover the wire between shield connectors, eliminating the need for a tubular shield and allowing shielding even with short wires, with brackets facilitating connection and crimping operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a tubular shield member is crimped to shield between devices, then shielding performance is improved, but the method cannot be applied when devices are closely connected due to crimper interference
Solution Approach 1:
The patent replaces the rigid tubular shield member with a flexible sheet-like shield member made of electrically conductive material. This sheet-like shield can be retro-fitted between closely connected devices by wrapping it around the wire after the connectors are in place, eliminating the need for pre-crimping and enabling shielding in short wire connection scenarios.
2Object-affected harmful factors
If a tubular shield member is used, then shielding is achieved, but the operation becomes complex requiring pre-mounting before connector assembly
Solution Approach 1:
The patent inverts the traditional sequence of shield installation. Instead of mounting the tubular shield before connector assembly (which requires complex pre-positioning), the sheet-like shield is installed after the connectors are assembled by wrapping it around the existing wire and connector assembly, greatly simplifying the operation.
3Length of moving object
If shield connectors are placed close to each other, then wire length is reduced, but crimping operation interferes between adjacent connectors
Solution Approach 1:
The patent performs the shield installation action after the connectors are already assembled and positioned close to each other, rather than requiring preliminary shield installation before connector assembly. This eliminates the crimper interference problem while maintaining short wire lengths.

AI summary
A wiring harness (10) for connecting a first device and a second device includes a first shield connector (20) to be connected to the first device, a second shield connector (30) to be connected to the second device, wires (40) arranged between the first shield connector (20) and the second shield connector (30), and a shield (50) made of an electrically conductive metal cloth. After the wires (40) are arranged between the first shield connector (20) and the second shield connector (30), the sheet-like shield (50) is mounted to cover the wires (40), thereby shielding between the first and second devices.
