FPCB Cable Terminal Protector Prevents Connector Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible printed circuit board (FPCB) cables in large-sized flat-panel display devices are prone to detachment from cable connectors due to increased distance and weight, leading to instability under external forces such as shock.
Innovation Solution
A flexible printed circuit board cable and cable connector assembly featuring a conductive line unit with a terminal protector that surrounds the terminal and is integrally formed with an insulating layer, along with a cable connector having a groove on its side surface, enhancing coupling reliability and preventing unintended detachment.

Engineering Contradiction Analysis
1Length of moving object
If the FPCB cable is lengthened to accommodate large-sized display devices, then the distance between FPCBs is increased, but the weight of the FPCB cable increases and it becomes easily detached from the cable connector
Solution Approach 1:
The FPCB cable assembly is divided into multiple components: the FPCB cable itself, a terminal protector extending from the conductive line unit, and a cable connector. The terminal protector acts as an intermediate segment that reinforces the connection interface, preventing the cable from bending or detaching while maintaining the required length for large display devices.
Solution Approach 2:
The terminal protector serves as an intermediary element between the FPCB cable and the cable connector. It extends from the conductive line unit and surrounds the terminal, providing mechanical reinforcement and protection at the critical connection point, thereby preventing detachment caused by the cable's own weight or external forces.
2Length of moving object
If the FPCB cable is lengthened to accommodate large-sized display devices, then the distance between FPCBs is increased, but the cable becomes prone to detachment under external forces such as shock
Solution Approach 1:
The terminal protector is installed beforehand at the connection interface to provide preventive reinforcement. It surrounds the terminal and extends from the conductive line unit, creating a protective structure that cushions against external forces such as shock or vibration before they can cause detachment, ensuring stable connection in large-sized display devices where cable length and flexibility are critical.

AI summary
An FPCB cable and cable connector assembly includes: a conductive line unit including a signal (conductive) line; a terminal exposing a portion of the signal (conductive) line; a terminal protector extending from a side of the conductive line unit and surrounding the terminal; and a cable connector coupled to the terminal. The cable connector includes an actuator pivotably coupled to the cable connector and configured to fix the FPCB cable to the cable connector, and the terminal protector is configured to surround the cable connector such that the FPCB cable is not unintentionally detached from the cable connector.
