Shield Connector Wire-Groove Layout to Prevent Shell Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shield connectors cause interference between wires and shells due to the regulation of wire positions, leading to potential interference issues.
Innovation Solution
The shield connector design includes a housing with a first and second shell, where the second shell has a wire holding portion with housing grooves that form regulatory grooves with a slanted portion to prevent interference between the shells and wires, allowing the wires to be spaced apart along a first direction orthogonal to the leading-out direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the positions of multiple wires are regulated by assembling the lower shell and the upper shell, then the wires are bundled and positioned, but the wires tend to interfere with the lower shell due to the regulation
Solution Approach 1:
The wire holding portion is divided into multiple housing grooves, with specific grooves forming regulatory grooves that guide wires separately. This segmentation allows wires to be positioned individually rather than as a bundled mass, preventing interference with the lower shell while maintaining organized wiring.
Solution Approach 2:
The regulatory groove acts as an intermediary structure between the housing and the wires. It provides a dedicated pathway that mediates the relationship between the wired and the lower shell, allowing wires to pass through in an organized manner without direct contact or interference with the lower shell.
2Object-affected harmful factors
If the wires are bundled with a distance maintained for interference prevention, then interference is reduced, but the wire harness size increases
Solution Approach 1:
The regulatory groove extends in the lengthwise direction of the housing, utilizing the longitudinal dimension to guide wires. This allows wires to be spaced apart along the length of the housing rather than requiring lateral separation, thereby maintaining compact wire harness dimensions while preventing interference.
Solution Approach 2:
The wire holding portion has differentiated local structures: some housing grooves form regulatory grooves for wire guidance, while others provide general holding. This local differentiation allows precise wire positioning only where necessary, maintaining compact overall size while preventing interference in critical areas.

AI summary
A shield connector includes a second shell attached at a position opposite to a first shell with a part of a housing interposed between the first shell and the second shell. The second shell has a wire holding portion that holds four wires led out toward a leading-out direction between the first shell and the second shell. The wire holding portion has four housing grooves that are formed toward a position where the four wires are bundled, and each houses one of the four wires such that the four wires are spaced apart from one another along a first direction. Two of the four housing grooves form regulatory grooves. The regulatory groove includes a first portion formed along a leading-out direction, and a second portion that is a portion formed to be slanted with respect to the leading-out direction.
