Wiring Substrate Extension Part for Connector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductive substrate modules experience insulation failure and short-circuit issues due to tilting and peeling of detachable connectors, which can lead to contact with the conductive board, causing insulation and short-circuit failures.
Innovation Solution
The detachable connector is fixed against an extension part of the wiring pattern, preventing tilting and peeling, thus maintaining insulation integrity and avoiding contact with the conductive board, and allowing for low-cost connection with the fixed connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable connector is mounted on a conductive board with an insulation layer, then the assembly flexibility and ease of operation are improved, but the reliability deteriorates due to insulation failure and short-circuit risk when the connector tilts or peels off
Solution Approach 1:
The patent introduces an extension part of the wiring pattern as an intermediary element between the detachable connector and the conductive board. This extension part provides a dedicated abutment surface that maintains proper connector positioning and prevents direct contact between the connector and the conductive board, thereby eliminating the short-circuit risk while preserving assembly flexibility
Solution Approach 2:
The extension part of the wiring pattern serves as a protective cushioning structure positioned in advance between the detachable connector and the conductive board. It prevents the connector from tilting or peeling off by providing a stable abutment surface, thereby preventing insulation failure and short-circuit risks before they can occur
2Ease of operation
If the detachable connector is allowed to move freely for ease of connection, then the ease of operation is improved, but the stability of the object deteriorates due to tilting and peeling
Solution Approach 1:
The extension part of the wiring pattern acts as an intermediary that provides a stable abutment surface for the detachable connector. This allows the connector to be easily attached and detached while maintaining stability during operation, as the extension part prevents excessive movement, tilting, or peeling
3Reliability
If a covering layer is added to prevent connector contact with the conductive board, then the insulation reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the insulation function with the existing wiring pattern by extending it to form an abutment surface. This integration eliminates the need for a separate covering layer, as the extended wiring pattern serves both electrical connection and mechanical support functions, thereby preventing connector contact with the conductive board without increasing structural complexity
Solution Approach 2:
The extension part of the wiring pattern performs multiple functions: it provides electrical connection, mechanical support, and insulation protection. By making the wiring pattern multi-functional, the patent eliminates the need for additional covering layers, thereby maintaining insulation reliability while avoiding increased device complexity

AI summary
A wiring substrate includes a wiring pattern that is formed on a surface of a conductive board via an insulation layer and an extension part that is extended from the wiring pattern. The extension part is disposed in a portion located immediately below a detachable connector. The detachable connector is connected to a fixed connector mounted on the wiring substrate and connected and fixed to the wiring pattern.
