Flexible Supporter for USB Connector PCB
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB application devices lack central support for their thin printed circuit boards, making them susceptible to damage from external pressing forces when connected with USB brackets.
Innovation Solution
Incorporating a flexible supporter between the printed circuit board and the casing of the USB application device, which disperses the pressing force by deforming and preventing damage to the board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the PCB carrying board is made thin (0.3mm to 1mm) to reduce connector thickness, then the connector thickness is reduced, but the central portion of the PCB becomes susceptible to damage from pressing force
Solution Approach 1:
A flexible supporter is introduced as an intermediary component between the PCB carrying board and the connector body. This flexible supporter has a central supporting structure that directly supports the central portion of the PCB, distributing the pressing force from USB connecting brackets and preventing PCB damage while maintaining thin connector thickness
Solution Approach 2:
The flexible supporter provides localized support specifically at the central area of the PCB where pressing force is most concentrated. The supporting structure includes a central supporting portion with increased thickness or reinforcement in the central region, providing targeted strength where needed without increasing overall PCB thickness
2Length of stationary object
If the PCB carrying board is made thin (0.3mm to 1mm), then the connector thickness is reduced, but the device loses structural support in the central area
Solution Approach 1:
The flexible supporter acts as a mediator that provides structural stability to the thin PCB. It includes a central supporting structure that maintains the PCB's shape and position, preventing deformation while keeping the overall connector thickness minimal
Solution Approach 2:
The flexible supporter is designed with flexible material that can dynamically adapt to pressing forces. It can deform elastically under load and return to its original shape, providing ongoing structural support and stability to the thin PCB throughout operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The flexible supporter effectively distributes external forces, enhancing the structural integrity and preventing damage to the printed circuit board, thereby ensuring the device's compact size and functionality.
Implementation Method 1
the flexible supporter is urged to be deformed by the press of the printed circuit board and to disperse the pressing force from the mating connector

AI summary
A USB application device includes a casing, a printed circuit board and a flexible supporter. The casing has a receiving space therein. The printed circuit board is completely receiving the printed circuit board and includes a top surface and a bottom surface opposite to the top surface. A plurality of contacts is disposed on the top surface of the printed circuit board. The flexible supporter is arranged in the casing and between the casing and the bottom surface of the printed circuit board. If the USB application device couples with a mating connector, the mating connector press the printed circuit board to urge the printed circuit board to press the flexible supporter. The flexible supporter is urged to be deformed by the press of the printed circuit board and to disperse the pressing force from the mating connector.
