Split Elastic Waterproofing Member for Easy Wiring Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproofing solutions for multi-core cables require complex configurations to prevent water ingress, making it difficult to easily attach an elastic waterproofing member to a wiring member.
Innovation Solution
A wiring module with a penetration accommodating portion that includes a first and second split waterproofing member, allowing for easy attachment by longitudinally splitting the elastic waterproofing member to accommodate the wiring member, with peripheral surface portions exceeding a semicircle for provisional holding and slits for deep-side penetration, enabling secure and efficient waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric wires penetrate through holes in a rubber plug, then water ingress is inhibited, but attachment complexity increases
Solution Approach 1:
The elastic waterproofing member is divided into a first split waterproofing member and a second split waterproofing member by longitudinally splitting the penetration accommodating portion. This segmentation allows the wiring member to be easily inserted by opening the split members, simplifying the attachment process while maintaining waterproofing performance through the elastic material's ability to seal around the wiring member.
2Ease of operation
If the elastic waterproofing member is split longitudinally, then ease of attachment improves, but structural integrity may be compromised
Solution Approach 1:
The elastic waterproofing member utilizes dynamic properties of elastic materials, allowing the split members to be separated for attachment and then return to their original joined state. The elasticity provides restoring force that maintains structural integrity after attachment, enabling the member to flex and seal around the wiring member while maintaining overall strength.

AI summary
One object is to be able to easily attach an elastic waterproofing member to a wiring member. A wiring module (10) includes a wiring member (20), and an elastic waterproofing member (30, 130, 230, 330) in which a penetration accommodating portion (32) is formed that is capable of accommodating a portion in a longitudinal direction of the wiring member. The elastic waterproofing member includes a first split waterproofing member (36, 136) and a second split waterproofing member (38, 138), the first split waterproofing member and the second split waterproofing member are obtained by splitting the elastic waterproofing member so as to longitudinally split the penetration accommodating portion, and the first split waterproofing member and the second split waterproofing member are kept in a joined state, with a portion in a longitudinal direction of the wiring member accommodated in the penetration accommodating portion.
