Electric Wire Cover Hinge Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric wire covers fail to prevent misalignment caused by twisting of the hinge portion, leading to difficulties in closing the paired wire covers smoothly.
Innovation Solution
Incorporating a guide groove and a rotation restriction rib in the electric wire cover design, which are positioned close to the hinge portion, allowing the rotation restriction rib to slide in the guide groove during rotation, thereby restricting rocking between the paired wire covers and ensuring proper alignment.

1Object-affected harmful factors
If a thin plate-like hinge portion is used to connect the first and second electric wire covers, then the hinge portion has flexibility for rotation, but twisting of the hinge portion occurs during rotation, causing misalignment between the paired electric wire covers
Solution Approach 1:
A guide groove is introduced as an intermediary structure between the first and second electric wire covers. The guide groove receives and guides the rotation restriction rib during rotation, acting as a mediator that controls the rotational movement and prevents twisting of the hinge portion, thereby ensuring proper alignment between the paired covers
Solution Approach 2:
The rotation restriction rib and guide groove work together in a self-aligning mechanism. As the second electric wire cover rotates during closing operation, the rotation restriction rib automatically engages with the guide groove, which self-corrects any twisting tendency of the hinge portion and guides the cover into proper alignment without external intervention

AI summary
An electric wire cover includes: a first electric wire cover including a wire arrangement space like a groove opened on one side, and attached to a wire lead-out end of a connector housing; and a second electric wire cover formed integrally with the first electric wire cover through a hinge portion, and covering the wire arrangement space. A guide groove is provided in one of the first and second electric wire covers, and extends in a direction perpendicular to a rotation axis of the hinge portion. A rotation restriction rib is provided in the other electric wire cover and extends in the direction perpendicular to the rotation axis. The rotation restriction rib slides in the guide groove during rotating operation by the hinge portion so as to restrict rocking of the electric wire covers relative to each other.
