Stepped Wiring Terminal for EMI Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiring terminals in electronic devices are cumbersome for assembly and maintenance, lack electromagnetic shielding, and are not suitable for connecting multiple functional modules without exposing leads, leading to aesthetic issues and electromagnetic interference.
Innovation Solution
A wiring terminal with a base attached to a housing, featuring stepped conductor portions that allow leads to be positioned between the housing and electronic modules for electromagnetic interference shielding, and a simple, easy-to-install design that hides leads, facilitating connections between multiple modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional wiring terminals are used to connect power modules and functional modules, then electrical connection can be established, but the leads are exposed which causes aesthetic issues and electromagnetic interference
Solution Approach 1:
The lead is nested within the housing structure by positioning it between the housing wall and the electronic module. The stepped arrangement of conductor portions allows the lead to be concealed inside the housing, eliminating external exposure while maintaining electrical connection functionality.
Solution Approach 2:
The housing structure serves as an intermediary element that shields the lead from external electromagnetic interference. By positioning the lead between the housing wall and the module, the housing acts as a shielding barrier without requiring additional specialized shielding components.
2Ease of manufacture
If leads are exposed in conventional wiring terminals, then electrical connection is simple, but aesthetic appearance deteriorates and electromagnetic interference increases
Solution Approach 1:
The lead is nested within the housing structure by positioning it between the housing wall and the electronic module. The stepped arrangement of conductor portions allows the lead to be concealed inside the housing, eliminating external exposure while maintaining electrical connection functionality.
3Reliability
If conventional wiring terminals are used, then electrical connection between modules is achieved, but assembly and maintenance become cumbersome
Solution Approach 1:
The wiring terminal is segmented into distinct conductor portions (first and second conductor portions) with different spatial arrangements. This segmentation allows for modular assembly where each portion can be independently positioned and connected, simplifying the overall assembly process while maintaining reliable electrical connections.
Solution Approach 2:
The conductor portions are arranged in a stepped manner along the direction extending from the housing wall to the module, creating a three-dimensional configuration. This dimensional arrangement allows leads to be routed through the housing interior space, simplifying external connections while maintaining reliable electrical contact.
