Elliptical Protect Tube for Cable Separation in Combination Mold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing separate installation of electronic parking brake (EPB) cables and wheel speed sensor (WSS) cables in vehicles leads to cable management difficulties, affecting vehicle quality and lacking a suitable structure for separating cables between the motor and WSS.
Innovation Solution
A seal mold divided structure for combination cables, where the cables are fixed separately with a protect tube having an elliptical inner surface to prevent molding compound ingress, and a division molding portion that keeps the cables separated, along with a connector molding portion and protect tube to maintain cable separation and protect against damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If EPB cable and WSS cable are bound and connected together, then cable management is improved, but cable separation and identification become difficult
Solution Approach 1:
The combination cable is segmented into distinct EPB cable and WSS cable portions through the division molding portion, which creates a physical separation structure. This allows the cables to be managed together as a combination cable while maintaining clear separation and identification of individual cable functions through the molded division structure.
2Ease of operation
If cables are set separately in the vehicle, then cable identification is improved, but vehicle quality and manufacturing efficiency deteriorate
Solution Approach 1:
The EPB cable and WSS cable are merged into a single combination cable assembly with integrated connector housing. This combining approach improves manufacturing efficiency by reducing assembly steps while maintaining clear cable identification through the division molding portion that visually and physically distinguishes each cable's function within the unified structure.
3Ease of manufacture
If regular cylindrical protect tube is used, then manufacturing simplicity is maintained, but molding compound can infiltrate along the cable surface
Solution Approach 1:
The protect tube transitions from a regular cylindrical shape to an elliptical cross-section that closely fits the cable's winding displacement shape. This asymmetric, customized geometry prevents gaps between the protect tube and cable surface, blocking the infiltration path for molding compound while maintaining manufacturing feasibility through mold design.
4Reliability
If connector and first cable are molded together, then connection stability is improved, but cable separation from second cable becomes difficult
Solution Approach 1:
The molding process is segmented into two distinct portions: the connector molding portion that bonds the connector to the first cable, and the division molding portion that separates the first cable from the second cable. This segmentation allows strong connector-cable connection through integrated molding while simultaneously creating clear cable separation through the division structure.

AI summary
A seal mold divided structure for combination cable disclosed comprises the following structures: a first cable and a second cable separated from the combination cable; a connector provided at the end of the first cable; a division molding portion that molds the division part between the first cable and the second cable and keeps the first cable and the second cable separated from each other; a connector molding portion that molds the connection part between the connector and the first cable; and a protect tube, with its ends respectively fixed to the division molding portion and the connector molding portion to protect the first cable and prevent inflow of a molding compound.
