Connector for Circuit Board Electrical Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in connecting flexible circuit boards for LED light strips to printed circuit boards on display panels, as current methods involve high-temperature soldering or expensive plug-fit connectors, which are complex, risky, and prone to damage during reworking processes.
Innovation Solution
A circuit board device with a connector comprising a first and second portion that can press and separate the circuit boards electrically, eliminating the need for soldering or desoldering at high temperatures, and using a conductive sheet or adhesive tape for connection, allowing for easy assembly and disassembly without damaging the boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-temperature soldering is used to connect the flexible circuit board for LED light strip to the printed circuit board on display panel, then reliable electrical connection is achieved, but the complexity and risk of the process increases, and reworking becomes difficult
Solution Approach 1:
The patent introduces a connector as an intermediary component between the flexible circuit board and printed circuit board. This connector includes a first portion connected to the flexible circuit board and a second portion connected to the printed circuit board, with a connection section that can be electrically connected or disconnected. This intermediary device eliminates the need for direct high-temperature soldering between the two circuit boards, thereby reducing process complexity and risk while maintaining reliable electrical connection.
2Reliability
If soldering process is used to connect the circuit boards, then strong electrical connection is achieved, but the ease of operation and reworking process deteriorates due to high temperature requirements
Solution Approach 1:
The patent implements a dynamic connection mechanism where the connector can transition between connected and disconnected states. The connection section of the connector allows for easy connection and disconnection without requiring high-temperature soldering or desoldering processes. This dynamic design enables simple reworking operations while maintaining strong electrical connection when needed, directly addressing the contradiction between connection strength and ease of reworking.
3Ease of manufacture
If traditional connector with multiple parts is used to connect circuit boards, then electrical connection can be achieved without soldering, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated connector structure. The connector combines the functions of electrical connection, mechanical fixation, and alignment in one component. The first portion, second portion, and connection section work together as an integrated assembly that simplifies the overall manufacturing process while avoiding the complexity of traditional multi-part connectors with separate fasteners, insulators, and contact elements.
