Cable Support Structure on PCB Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The compactness of modern electronic devices limits the mounting space for clips that support cables on printed circuit boards (PCBs), making it difficult to securely attach cables due to the need for a substantial mounting area and adequate spacing from peripheral components.
Innovation Solution
The use of a conductive shield with a support member that includes a first part spaced apart from the conductive shield's sidewall and a second part extending from the first part, forming a fixing space for the cable, which reduces the required mounting space by allowing the cable to be stably fixed vertically and preventing horizontal movement, while the support member is surface-mounted on the PCB.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clip is used to support the cable on the PCB, then the cable can be securely attached, but the mounting space required increases
Solution Approach 1:
The support member is merged with the conductive shield to form an integrated structure. The support member includes a first part spaced apart from the conductive shield's sidewall and a second part extending from the first part, creating a unified assembly that reduces the number of separate components and mounting operations while maintaining cable support functionality
Solution Approach 2:
The support member utilizes vertical spacing between the first part and the conductive shield's sidewall to create a fixing space for the cable. This dimensional approach allows the cable to be positioned in the gap rather than requiring horizontal mounting area, effectively converting a 2D mounting problem into a 3D spatial solution
2Volume of moving object
If the PCB is made compact to reduce device size, then device compactness improves, but the mounting area for cable support decreases
Solution Approach 1:
The support structure utilizes the vertical dimension by spacing the first part apart from the conductive shield's sidewall to form a fixing space. This allows cable support functionality to be achieved in the vertical direction rather than requiring additional horizontal mounting area, enabling compact PCB design
Solution Approach 2:
The support member is positioned within or adjacent to the conductive shield structure, utilizing the existing shield's spatial envelope. The support member's first part is spaced apart from the sidewall while the second part extends toward the shield, nesting the support function within the overall shield assembly's footprint
