Flexible Circuit Flat Cable Inserter Detachment Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible circuit flat cables lack a detachment and displacement protection structure, leading to instability and poor mechanical and electrical contact stability during insertion, as the inserter can detach from the plastic member when subjected to external forces.
Innovation Solution
A detachment and displacement protection structure is integrated into the inserter positioning section, featuring a metal member and a plastic member with projecting lug sections, retention slots, and locking mechanisms to prevent displacement and detachment in the flat cable extension direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inserter is provided at the leading end of a flexible circuit flat cable to improve mechanical stability, then the stability of electrical engagement is improved, but the inserter can be separated from the plastic member when pushed rearward by a user, causing the plastic member to be no longer enclosed by the metal member and lose its positioning function
Solution Approach 1:
The plastic member is nested within the metal member, with the metal member forming a hollow section that receives and encloses the plastic member. This nested configuration ensures that the plastic member remains securely positioned within the metal member even when external forces are applied, preventing separation while maintaining the positioning function on the flexible circuit flat cable.
2Manufacturing precision
If the metal member is fit over the plastic member to enclose it, then the plastic member is properly positioned on the predetermined zone, but without a detachment protection structure, the inserter may be separated from the plastic member in the direction of extension of the flat cable when acted upon by external force
Solution Approach 1:
The plastic member is first positioned on the predetermined zone of the flexible circuit flat cable, and then the metal member is fit over the plastic member to enclose it. This preliminary positioning action ensures that the plastic member is correctly placed before the metal member is assembled, maintaining positioning accuracy while the subsequent enclosing action provides connection reliability.

AI summary
Disclosed is a detachment and displacement protection structure for insertion of flexible circuit flat cable. An inserter positioning section is formed on a flexible circuit flat cable and coupled with an inserter, which includes a metal member and a plastic member. In assembling, the plastic member is first positioned on a first surface of the inserter positioning section of the flexible circuit flat cable, and then the metal member is fit over the plastic member. A detachment and displacement protection structure is provided on the inserter positioning section to constrain the inserter from displacing and detaching in a flat cable extension direction due to being acted upon by an external force when the inserter is positioned on the inserter positioning section.
