Connector Assembly Shielding and Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connector assemblies fail to provide effective shielding against external interference, leading to signal fading and distortion during transmission, which compromises their ability to meet signal transmission requirements.
Innovation Solution
The connector assembly incorporates a primary and secondary conductive terminal set with projection areas and positioning structures, where the secondary conductive terminal provides shielding for the primary terminal by having a larger projection area, and uses inner and outer insulation terminal blocks with positioning and fastening structures to ensure secure coupling and bonding, along with jumper conductors for electrical interconnection without additional jumpers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connector assembly structure is used, then device complexity is reduced, but shielding performance deteriorates causing signal fading and distortion
Solution Approach 1:
The connector assembly is segmented into multiple functional components: primary conductive terminals for signal transmission, secondary conductive terminals for shielding, and insulation terminal blocks for positioning. This segmentation allows each component to perform its specific function optimally, with the secondary terminals providing shielding without interfering with the primary signal transmission function.
Solution Approach 2:
The patent implements a nested structure where secondary conductive terminals are positioned to surround and shield the primary conductive terminals. The insulation terminal blocks are nested within the connector assembly to provide positioning structures that hold both primary and secondary terminals in their respective predetermined positions, creating a layered protective configuration.
2Object-affected harmful factors
If secondary conductive terminal with larger projection area is added for shielding, then shielding performance is improved, but device complexity increases
Solution Approach 1:
The secondary conductive terminals are designed with larger projection areas specifically positioned around the primary terminals to provide localized shielding where it is most needed. The insulation terminal blocks provide localized positioning structures that ensure the secondary terminals are placed precisely where they can effectively shield the primary terminals from external interference.
3Reliability
If insulation terminal block with positioning structures is used, then connection reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The insulation terminal blocks are designed with pre-formed positioning structures including positioning holes and positioning protrusions that are created during the molding process. These positioning structures are prepared in advance to receive and hold the primary and secondary conductive terminals in their correct positions, eliminating the need for complex post-assembly positioning operations.

AI summary
A connector assembly is provided. The connector assembly allows a conductive terminal to provide shielding to reduce any effect of external interference on signal transmission of the connector assembly so as to meet signal transmission requirements for the connector assembly, and with the use of a jumper conductor, at least partial conductive terminals on the connector assembly can be electrically interconnected with no need of any additional jumper, such that an electronic device using such connector assembly can be made compact in size desirably.
