Cable Connecting Mechanism Hinge Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cable connecting mechanisms are prone to hinge breakage due to forces transmitted from cables to the lid and bottom surface members, which can cause them to move relative to each other.
Innovation Solution
A cable connecting mechanism featuring a slider and slider housing member with specific engagement structures and cable extension parts that restrict movement and distribute loads, preventing the lid and bottom surface members from moving relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are routed to connect to the joint piece inside the case, then the cable connecting function is achieved, but the cables transmit forces to the lid member or bottom surface member via the joint piece, causing the lid and bottom surface members to move relative to each other and risking hinge breakage
Solution Approach 1:
A wall portion is introduced as an intermediary element between the cable routing path and the lid member. This wall portion intercepts and blocks the force transmission path from the cable to the lid member, preventing the cable-induced forces from causing relative movement between the lid and bottom surface members, thereby protecting the hinge from breakage while maintaining the cable connecting function
2Device complexity
If the case structure is simplified with fewer engagement structures, then the device complexity is reduced, but the ability to maintain the closed state against cable forces is compromised
Solution Approach 1:
The wall portion is positioned in a different spatial dimension relative to the traditional engagement structures. Instead of adding more engagement structures in the same plane, the wall portion extends into the interior space of the case to block force transmission paths, achieving enhanced reliability with minimal increase in device complexity

AI summary
Provided is a cable connecting mechanism including a slider and a slider housing member. The slider housing member has a lid member, a bottom surface member, a pair of side walls, a one-end-side hinge connecting the lid member and the bottom surface member, an another-end-side hinge connecting the member and the bottom surface member, a first engagement structure provided on an outer surface closer to one end of the slider housing member than the one-end-side hinge, a second engagement structure, a third engagement structure, a fourth engagement structure, a cable extension part, and a wall portion arranged to be sandwiched between the one-end-side hinge and the another-end-side hinge. In a closed state, when a load is applied to the cable so as to release the closed state by pressing at least one of the lid member and the bottom surface member, the wall portion abuts against an outer circumference of another one of the lid member and the bottom surface member, to restrict a movement of the lid member or the bottom surface member in an alignment direction of the pair of side walls. Therefore, the hinge is not easily broken.
