Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors, such as crimp connectors, face space limitations and require laborious installation due to different types of protective grounding connections necessitating screws, limiting the number of connections that can be accommodated and complicating assembly.
Innovation Solution
A connector insert with a protective grounding plate that allows for high-density connections, using power connections as protective grounding connections, featuring a metal plate with elastic arms and a slot for easy assembly and disassembly, and accommodating multiple connections including power, protective grounding, and coding connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw fastening is used for protective grounding connections, then reliable electrical contact is achieved, but installation becomes laborious and time-consuming
Solution Approach 1:
The patent replaces the mechanical screw fastening system with an elastic contact system. The elastic protective grounding plate uses spring force to maintain reliable electrical contact without requiring screws, thereby eliminating the laborious installation process while maintaining contact reliability.
Solution Approach 2:
The elastic protective grounding plate automatically adjusts and maintains electrical contact through its inherent elasticity. The spring-loaded design provides self-adjusting contact pressure, eliminating the need for manual screw tightening and adjustment by technicians.
2Reliability
If different types of connections (power and protective grounding) are used, then proper electrical function is achieved, but the number of connections that can be accommodated is limited
Solution Approach 1:
The patent implements a universal connection design where the same type of connection hole can accommodate both power connections and protective grounding connections. The elastic protective grounding plate works with standard connection holes, allowing flexible configuration and increasing the number of connections that can be accommodated in the insert housing.
3Ease of operation
If elastic protective grounding plate is used, then quick assembly and disassembly is enabled, but manufacturing complexity increases
Solution Approach 1:
The protective grounding plate is segmented into multiple independent elastic arms, each capable of independent deflection and contact. This segmentation allows the complex elastic structure to be manufactured as separate simple components that can be assembled together, reducing overall manufacturing complexity while maintaining the quick assembly/disassembly functionality.

AI summary
An insert for a connector is provided having: an insert housing, wherein a cavity of the insert housing has multiple connection-accommodating holes for accommodating multiple connections, and wherein the multiple connections comprise at least one protective grounding connection; a holding plate, which is attached to a connection side of the insert housing in order to hold the multiple connections in the cavity; and a protective grounding plate, which serves for electrical contact with the protective grounding connection. The insert can accommodate more connections, whereby a high-density connector is provided, wherein power connections and protective grounding connections of the same type can be used in order for quick assembly and disassembly to be realized, whereby it is also possible for customers to replace the connections according to actual use.
