Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector receptacles are limited by their large size, complex component structures, lack of shielding, and absence of grounding, which restricts their application to low-voltage use and fails to effectively mitigate electromagnetic interference.
Innovation Solution
A compact electrical connector receptacle design featuring a shielded structure with a conductive shield cover, a terminal unit, and a grounding assembly, which includes a resiliently-biased grounding element and fastening structure to connect the outer shield to the wire shield, enabling use in both low- and high-voltage applications while reducing electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prior art electrical connector receptacles are used, then they can be used for low-voltage applications, but they are large and contain many component parts
Solution Approach 1:
The patent combines multiple functions into a single integrated housing structure that serves as both the receptacle body and the shield. The housing integrates terminal blocks, fuse holders, and electromagnetic shielding in one unified component, eliminating the need for separate shield assemblies and reducing overall component count while maintaining compatibility with both low-voltage and high-voltage applications
Solution Approach 2:
The receptacle design incorporates universal features that allow it to function in both low-voltage and high-voltage applications. The housing structure includes integrated shielding and grounding capabilities that are applicable across different voltage levels, making the device versatile without requiring multiple specialized components
2Adaptability or versatility
If prior art electrical connector receptacles are used, then they can be used for low-voltage applications, but they lack shielding and grounding for high-voltage applications
Solution Approach 1:
The patent merges the shielding function directly into the housing structure itself. The housing is designed with conductive materials and integrated grounding paths that provide electromagnetic interference protection while maintaining structural integrity. This integration ensures that shielding and grounding are inherently present in both low-voltage and high-voltage applications without requiring additional separate components
Solution Approach 2:
The housing structure acts as an intermediary element that provides both mechanical support and electromagnetic shielding. The conductive housing serves as a mediator between the internal components and the external environment, providing a grounded shield that protects against electromagnetic interference while allowing the receptacle to function across different voltage levels
3Device complexity
If prior art electrical connector receptacles are used, then they have a simple structure, but they are not shielded and do not reduce electromagnetic interference
Solution Approach 1:
The patent combines the shielding function with the structural housing into a single integrated component. The housing is designed with conductive properties and integrated grounding paths that provide electromagnetic interference protection while maintaining structural integrity. This integration ensures that shielding and grounding are inherently present in both low-voltage and high-voltage applications without requiring additional separate components

AI summary
An electrical connector receptacle includes a shield cover, a terminal unit and a fastener structure. The shield cover defines a cavity and an opening into the cavity and has a base panel with a base panel hole formed therethrough. The terminal unit has a first terminal unit mounting block having a first terminal unit mounting block hole, a second terminal unit mounting block having a second terminal unit mounting block hole, a first terminal assembly and a second terminal assembly. The first and second terminal unit mounting blocks are connected together in a stacked manner and are disposed in the cavity. With the first terminal unit mounting block hole, the second terminal unit mounting block hole and the base panel hole being in registration with one another, the fastener structure extends therethrough from the base panel and projects outwardly from the opening.
