Flexible Cable Pressing Mechanism for Stable PCB Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing mechanisms for flexible cables and printed circuit boards are inflexible and prone to instability, leading to loose connections and signal disruptions due to fixed specifications and loosening over time.
Innovation Solution
A pressing mechanism comprising a positioning device, a pressing device, and a guide rail, with adjustable components such as splicing guide rails and modular pressing heads, allows for precise alignment and secure connection of flexible cables of varying widths, ensuring stable contact and easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connector with fixed specification is used to press the flexible cable, then the connection structure is simple, but the adaptability to different cable specifications is poor
Solution Approach 1:
The pressing mechanism employs a movable pressing head that can slide along the flexible cable in the width direction, transforming a static fixed-specification connector into a dynamic adjustable system. This allows the pressing head to adapt to different cable widths while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and structural complexity.
Solution Approach 2:
The pressing mechanism changes the width parameter of the pressing head by allowing it to move along the cable width direction. This parameter adjustment enables the same pressing mechanism to accommodate flexible cables of different specifications, improving adaptability without requiring multiple different connectors.
2Adaptability or versatility
If a fixed specification connector is used, then the device structure is simple, but the pressing range cannot be adjusted for different cable widths
Solution Approach 1:
The pressing head is designed to be movable along the width direction of the flexible cable, creating a dynamic adjustment mechanism. This allows the pressing range to be adjusted for different cable widths while keeping the overall mechanism relatively simple, avoiding the need for completely different connectors for each cable specification.
3Reliability
If a connector is installed on the printed circuit board, then the connection is initially stable, but it may loosen after multiple closures causing instability
Solution Approach 1:
The pressing mechanism allows the pressing head to move and adjust its position along the flexible cable width direction during operation. This dynamic adjustment capability enables the connector to compensate for loosening that occurs after multiple closures, maintaining connection stability and durability over time rather than degrading as conventional fixed connectors do.

AI summary
A pressing mechanism and a display device are disclosed. The pressing mechanism includes a guide rail extending in a direction consistent with a width direction of a flexible cable, a positioning device connected to a side of the guide rail facing towards a printed circuit board, and a pressing device sleeved on the guide rail and operative to move along the guide rail and used to press a junction between the printed circuit board and the flexible cable. The positioning device includes a first and a second positioning piece respectively arranged on both sides of the pressing device. The second positioning piece is movably connected to the guide rail and is operative to move along the guide rail. The first and the second positioning piece are detachably connected to the printed circuit board, and respectively abut against both sides of the flexible cable in the width direction.
