Connector Cover With Movable Rear Shield for Narrow Space Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector covers face issues with detachment due to excessive bending force, which can lead to breakage of locking parts, especially when used in narrow spaces where the wire is bent, causing an increased load on the fulcrum and potentially detaching from the connector.
Innovation Solution
A connector cover design featuring a rear cover that transitions to a rearward extension released state when pushed by the wire, making the connector cover shorter and reducing the load on the fulcrum, while being coupled to the cover body via a coupling portion to prevent detachment, with locking forces ensuring the cover remains locked to the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the rear cover is held in a rearward extending state to extend rearwardly of the connector, then the connector can be inserted into narrow spaces, but the load on the fulcrum increases due to leverage, causing detachment
Solution Approach 1:
The rear cover is designed to be movable between a rearward extending state and a rearward extension released state. When the wire is bent, the rear cover transitions to the released state, dynamically adjusting the length of the connector cover to reduce the load on the fulcrum and prevent detachment, while maintaining the ability to extend for insertion into narrow spaces
2Adaptability or versatility
If the wire is bent into contact with the rear cover, then the connector can accommodate wire routing, but excessive bending force transfers to the base portions, causing breakage of locking parts
Solution Approach 1:
The rear cover acts as an intermediary element between the wire and the base portions. When the wire is bent, the rear cover absorbs and redirects the force, preventing direct transmission of excessive bending force to the locking parts of the base portions, thereby protecting them from breakage

AI summary
A connector cover (1) for protecting a wire (80) extending rearward from a connector (100) includes a cover body (10) mountable to extend rearwardly of the connector (100) and fixed to the connector (100), a rear cover (50) disposed behind the cover body (10), a coupling (70) coupling the rear cover (50) and the cover body (10), and extending shape holding portions (60) capable of holding the rear cover (50) in a rearward extending state to extend rearwardly of the connector (100). The rear cover (50) transitions to a rearward extension released state where the rearward extending state is released by being laterally pushed by the wire (80).
