Connector With Elastic Support Member For Flexible Conductor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for flexible conductors often damage the conductors during connection due to excessive force, compromising the reliability of the electrical connection.
Innovation Solution
A connector design that uses a combination of support members and pushing members to ensure the flexible conductor is not rubbed by large forces during connection, with the support members being elastically deformed to apply a pressing force without damaging the conductor, and the pushing members inserted to secure the connection without direct contact that could cause damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the projection of the base member is inserted into the projection accommodating portion together with the flexible substrate to press the flexible conductor against the inner surface, then electrical connection is achieved, but the flexible conductor may be damaged due to large rubbing force
Solution Approach 1:
A support member is introduced as an intermediary component between the base member and the flexible substrate. The support member has a projection that fits into the projection accommodating portion, and the flexible substrate is positioned between this support member projection and the base member projection. This intermediary structure distributes the pressing force and prevents direct rubbing contact between the base member and flexible substrate, thereby protecting the flexible conductor while maintaining electrical connection reliability.
Solution Approach 2:
The support member is installed beforehand to provide cushioning protection for the flexible substrate. By positioning the support member with its projection into the accommodating portion before final assembly, it creates a protective buffer that absorbs and distributes the insertion force, preventing damage to the flexible conductor during the connection process.
2Reliability
If large force is applied to ensure predetermined contact force between flexible conductor and contact, then electrical connection reliability is improved, but the flexible conductor may be damaged
Solution Approach 1:
The support member serves as a force-distributing intermediary that transforms concentrated large force into distributed pressing force. The projection of the support member fits into the projection accommodating portion and presses the flexible substrate uniformly, ensuring adequate contact force for reliable electrical connection while preventing localized stress concentration that could damage the flexible conductor.
Solution Approach 2:
The support member changes the force distribution parameters by introducing a larger contact area. Instead of a small projection directly pressing the flexible conductor, the support member's projection distributes the force over a broader area of the flexible substrate, maintaining necessary contact pressure while reducing peak stress on the conductor.
