Wire Protective Cover With Bending Retainer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical wire protective covers have low assembly workability due to their design, where the opening size is wider than the bundled wires, leading to easy removal during assembly.
Innovation Solution
Incorporating temporary wire retaining pieces that protrude and undergo bending deformation to narrow the opening, allowing easy insertion and preventing removal of the electrical wire protective cover from the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening size of the wire receiving channel is made wider than the bundled electrical wires, then the electrical wires can be easily inserted, but the electrical wire protective cover can be easily removed from the electrical wires during assembly
Solution Approach 1:
The temporary wire retaining piece is designed to be movable rather than fixed. It can bend inward to widen the opening for wire insertion, then return to its original position to narrow the opening and prevent cover removal. This dynamic behavior resolves the contradiction between ease of insertion and assembly stability.
Solution Approach 2:
The opening size of the wire receiving channel is changed dynamically through the bending deformation of the temporary wire retaining piece. The opening size parameter transitions from a larger value (during insertion) to a smaller value (during retention), resolving the contradiction between ease of operation and reliability.
2Ease of operation
If the opening size of the wire receiving channel is made wider than the bundled electrical wires, then the electrical wires can be easily inserted, but the assembling workability is lowered due to easy removal
Solution Approach 1:
The temporary wire retaining piece dynamically changes the opening size during the assembly process. It bends inward during insertion to maintain high productivity, then returns to its original position to prevent accidental removal, thereby improving overall assembling workability.
Solution Approach 2:
The temporary wire retaining piece is pre-positioned to protrude from the cover body, creating a preliminary constraint that guides wire insertion while preventing premature removal. This preliminary action improves assembling workability by reducing errors and rework.

AI summary
An electrical wire protective cover is assembled to a connector to cover an electrical wire pulled out of the connector. The electrical wire protective cover includes: a cover body configured to receive the electrical wire and having a wire receiving channel with an opening along a wire extending direction of the electrical wire; and a temporary wire retaining piece protruding from the cover body in a direction narrowing the opening of the wire receiving channel, and configured to allow the electrical wire to be inserted by a bending deformation of the temporary wire retaining piece into an inside of the wire receiving channel and prevent a movement of the electrical wire received in the wire receiving channel to an outside of the wire receiving channel.
