Cable Assembly Connector Front Faceplate Electromagnetic Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable assemblies with connectors face challenges in effectively suppressing electromagnetic wave leakage from the front face side of the housing, where the contactor is located, despite successful suppression in the circumferential direction.
Innovation Solution
The cable assembly incorporates a housing with a conductive contactor, a cable, a rear faceplate, and a front faceplate, where the housing is interposed between the rear and front faceplates, and fixed using a screw member extending in the front and rear direction, ensuring the contactor area is completely covered by the front faceplate, thereby enhancing electromagnetic wave suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the front faceplate is added to cover the contactor area, then electromagnetic wave leakage is suppressed, but the device complexity increases
Solution Approach 1:
The front faceplate, rear faceplate, and main housing are merged into an integrated assembly using fixing members. This combining approach creates a unified shielding structure that functions as a single system, reducing the operational complexity despite adding components. The merged structure provides comprehensive electromagnetic shielding while maintaining assembly simplicity through the use of standard fixing members.
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
This configuration reliably suppresses electromagnetic wave leakage from the housing, providing more effective shielding compared to previous designs.
Implementation Method 1
the front faceplate is disposed on the mate connector opposing part of the front side of the housing and encloses the front side of the housing... the leakage of electromagnetic waves from the housing can be more reliably suppressed
