Sliding PCB Connector for Strong Yet Replaceable Board Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges with compatibility and replacement, leading to increased costs and waste due to poor compatibility between different types of connectors and electronic components, and welded connectors that cannot be disassembled.
Innovation Solution
A connector design featuring a hard circuit board with a conductive part and a soft circuit board with a contact part, connected via a sliding connecting piece, allowing for easy disassembly and replacement, with a gold-plated contact spring for stable electrical connections and a sealing gasket for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welded connectors are used to achieve fixed connection, then connection strength is improved, but disassembly and replacement capability deteriorates
Solution Approach 1:
The connector is divided into separate components: a connecting piece with connecting ends, a first circuit board with a first connecting end, and a second circuit board with a second connecting end. These segmented parts can be assembled and disassembled independently while maintaining strong connections during use.
Solution Approach 2:
The connecting piece is designed to be movable relative to the circuit boards during assembly and disassembly, but provides a fixed, stable connection when assembled. The dynamic capability allows for easy installation and replacement while maintaining connection strength during operation.
2Adaptability or versatility
If electronic components are replaced frequently, then adaptability is improved, but cost and waste increase
Solution Approach 1:
The connector design allows for easy disassembly and replacement of the connecting piece and circuit boards. When components need replacement, only the necessary parts are removed and discarded, while the connector structure itself can be retained and reused, reducing overall waste and cost.
3Reliability
If conductive parts with gold plating are used, then electrical connection stability is improved, but manufacturing cost increases
Solution Approach 1:
Gold plating is applied selectively to specific contact surfaces and conductive parts where electrical connection stability is most critical, rather than coating the entire connector. This localized application maintains electrical reliability while reducing material costs and manufacturing complexity.
