Shield Receiving Member Structure for Continuous Wire Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield receiving members with discontinuous circumferential ends risk significant disconnection, leading to reduced wire holding force.
Innovation Solution
A shield receiving member design with a plate-shaped body featuring recesses and protrusions, along with first and second locking portions that engage the shield and outer sheath, ensuring continuous engagement without significant disconnection, enhancing wire holding force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the shield receiving member is bent such that two end portions in the circumferential direction face each other to form a tubular shape, then the wire holding force is improved through recess engagement, but the recess may be largely disconnected in the circumferential direction between the two end portions, reducing the effectiveness of wire holding
Solution Approach 1:
A bridge portion is introduced as an intermediary element connecting the two end portions of the shield receiving member in the circumferential direction. This bridge portion fills the gap between the end portions, ensuring continuous engagement with the shield while maintaining the tubular shape's wire holding capability. The bridge portion acts as a mediator that preserves both the structural integrity and the functional effectiveness of the recess engagement.
Solution Approach 2:
The shield receiving member is divided into distinct segments: end portions, a bridge portion connecting them, and locking portions. This segmentation allows the bridge portion to specifically address the continuity issue between end portions while the locking portions maintain the wire holding function. The segmented structure enables independent optimization of each component's function.
2Strength
If locking portions are added to engage both the shield and outer sheath, then the wire holding force is enhanced, but the device complexity increases
Solution Approach 1:
The locking portions are merged with the existing shield receiving member structure rather than being separate components. The locking portions are formed as integral parts of the plate-shaped body, combining the functions of shield engagement, outer sheath engagement, and structural support into a single unified component. This merging approach enhances wire holding force while minimizing the increase in device complexity.
Solution Approach 2:
The locking portions serve multiple functions simultaneously: they engage with the shield to prevent radial movement, engage with the outer sheath to prevent axial movement, and maintain the overall structural integrity of the assembly. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving enhanced wire holding force.

AI summary
A shield receiving member includes a body part that extends in a circumferential direction and in which two end portions in the circumferential direction face each other. One of the two end portions of the body part in the circumferential direction has a recess that is recessed in the circumferential direction, and the other of the two end portions has a protrusion that protrudes in the circumferential direction and is disposed inside the recess. The body part has a first locking portion and a second locking portion that are bent from the outer circumferential surface side to the inner circumferential surface side, the first locking portion and the second locking portion extend in the circumferential direction from one end to the other end, respectively, and are arranged side-by-side in an axial direction intersecting the circumferential direction.
