Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield wire grounding structures for electric equipment are cumbersome and prone to damage due to the need for manual installation and exposure of components, which complicates the grounding process and increases the risk of external interference.
Innovation Solution
A shield wire grounding device that integrates a grounding member with the shield wire and insulating member through injection molding, featuring a locking protrusion for secure connection and a conductive plastic material to facilitate easy integration with the electric equipment housing, thereby reducing exposure and improving workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate terminal is used to ground the shield wire to the electric equipment housing, then the grounding function is achieved, but the work complexity increases and installation time is extended
Solution Approach 1:
The patent combines the terminal and grounding member into a single integrated grounding member. The grounding member includes a terminal portion for connecting to the shield wire and a grounding portion for contacting the electric equipment housing, eliminating the need for separate terminal installation and reducing work complexity while maintaining grounding reliability
2Ease of operation
If the shield wire and terminal are exposed to the outside for connection, then the connection is achieved, but the shield wire becomes vulnerable to external interference and damage
Solution Approach 1:
The patent nests the shield wire connection within the integrated grounding member structure. The terminal portion is incorporated into the grounding member, which then connects to the housing, providing protective coverage and reducing exposure to external interference while maintaining connection capability
3Reliability
If manual installation and bending of the terminal is required, then the grounding connection is achieved, but the installation time and labor requirements increase
Solution Approach 1:
The patent designs the grounding member with pre-formed terminal and grounding portions that are ready for installation. The integrated structure eliminates the need for on-site bending and manual assembly, allowing for quick installation while ensuring reliable grounding connection
