Shield Connector With Auxiliary Bracket For Bent Wire Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield connectors have complex structures and difficult attachment configurations, which hinder the demand for smaller, lighter, and cost-effective components in vehicles, particularly in configurations where electric wires are bent at angles.
Innovation Solution
A shield connector design featuring a connector housing, electric wires, a shield conductor, and a shield attachment member with a main and auxiliary attachment member, allowing for easy attachment and reduced complexity by eliminating one bracket and shield conductor, and utilizing auxiliary members to facilitate attachment at multiple positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional shield connector configuration with two brackets and two shield conductors is used, then the shielding coverage is complete, but the structure becomes complex and the attachment operation becomes difficult
Solution Approach 1:
The patent extracts and eliminates one bracket and one shield conductor from the conventional configuration. Specifically, the housing includes only one first engagement portion instead of two, and the shield attachment member includes only one first connection portion and one conductor holding portion instead of two sets. This reduction maintains sufficient shielding coverage for bent electric wires while simplifying the overall structure and reducing component count.
Solution Approach 2:
The patent inverts the conventional approach by positioning the shield conductor on the outer side of bent electric wires rather than requiring it to be on the inner side. This inversion allows effective shielding with a single shield conductor, eliminating the need for the second shield conductor and its corresponding bracket, thus simplifying the structure while maintaining shielding effectiveness.
2Ease of operation
If the first and second connection portions are directly attached to the housing at the same time, then the attachment is complete, but the attachment operation becomes difficult due to positioning constraints
Solution Approach 1:
The patent segments the attachment process into two distinct stages by introducing an auxiliary attachment member. The first connection portion is attached to the first engagement portion in the first stage, while the second connection portion is attached to the second engagement portion in the second stage. This segmentation allows each attachment operation to be performed independently without positioning conflicts, making the overall attachment process easier to execute.
Solution Approach 2:
The auxiliary attachment member acts as an intermediary that facilitates the sequential attachment process. It includes a second connection portion that engages with the second engagement portion and a third connection portion that connects to the housing. This intermediary structure enables the second attachment operation to be performed after the first, without interfering with the already-attached first connection portion.
3Device complexity
If the shield attachment member is made compact with minimum auxiliary attachment member, then the structure is simplified, but the attachment stability may be compromised
Solution Approach 1:
The patent applies local quality by concentrating the attachment functions in specific localized regions. The auxiliary attachment member includes engagement portions and connection portions positioned at specific locations on the housing to achieve stable attachment. The engagement portions engage with corresponding portions on the housing at strategically chosen positions, ensuring stability without requiring a large or complex auxiliary attachment member structure.
