Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication cables face challenges in enhancing both waterproof performance and assemblability, with existing solutions not effectively addressing these concurrent requirements.
Innovation Solution
A communication cable design featuring a waterproof rubber plug and a holder divided into first and second members, where the holder covers the outer peripheral surface of the rubber plug, improving waterproof performance and assemblability by allowing easier mounting and reduced component costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof rubber plug is used to improve waterproof performance, then waterproof performance is improved, but device complexity increases
Solution Approach 1:
The holder is divided into a first holder and a second holder that can be assembled together. This segmentation allows the waterproof structure to be implemented in a modular way, improving waterproof performance while keeping each individual component relatively simple, thus managing overall device complexity.
Solution Approach 2:
The rubber plug is accommodated within the holder structure, and the terminal portion is accommodated within the housing. This nested arrangement integrates multiple waterproofing elements into a compact unified structure, improving waterproof performance without proportionally increasing device complexity.
2Reliability
If a holder is added to cover the rubber plug for improved waterproof performance, then waterproof performance is improved, but device complexity increases
Solution Approach 1:
The holder serves multiple functions: it holds the rubber plug in position, provides additional waterproof protection, and structures the overall assembly. By making the holder multi-functional, the patent improves waterproof performance without adding unnecessary additional components, thus managing device complexity.
3Ease of operation
If the holder is divided into first and second members for improved assemblability, then assemblability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The holder is segmented into a first holder and a second holder that assemble together. This segmentation improves assemblability by allowing the holders to be fitted around the rubber plug in stages, making the assembly process more manageable and easier to perform correctly.
4Ease of operation
If a divided holder structure is used to improve assemblability, then assemblability is improved, but device complexity increases
Solution Approach 1:
The holder is divided into two separate holders that can be easily assembled together. This segmentation improves assemblability by breaking down a potentially complex single-piece holder into simpler modular components that are easier to manufacture and assemble.

AI summary
A communication cable is provided with a communication line, a terminal portion connected to an end part of the communication line, a housing for accommodating the terminal portion, a waterproof rubber plug and a holder. The rubber plug is held in close contact with an outer periphery of the communication line and partially accommodated in the housing. The holder is mounted on the housing to hold the rubber plug. The rubber plug includes a close-contact portion and an outer side portion located behind the close-contact portion and outside the housing. The close-contact portion is located behind the terminal portion and held in close contact with the outer periphery of the communication line and an inner surface of the housing. The holder covers an outer peripheral surface of the outer side portion over an entire periphery. The holder is divided into a first member and a second member.
