Plug Contact Connection System for Single-Row Housing Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection systems for single-row housings require a time-consuming method using tools to attach connecting elements, which complicates the process and increases the risk of faulty wiring due to the need for precise alignment and attachment of conductors to small connection areas.
Innovation Solution
A connection system utilizing plug contacts and fastening elements, such as snap arms, allows for tool-free attachment of connecting elements to the single-row housing, with multiple connecting areas and encoding for clear assignment, enabling secure and efficient electrical contact across the housing's length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw-type terminal or spring-loaded terminal is used for connection, then reliable electrical contact is achieved, but the attachment process becomes time-consuming and requires tools
Solution Approach 1:
The patent replaces the traditional screw-type or spring-loaded terminal mechanism with a plug contact system that uses a simple insertion motion instead of threaded rotation or spring compression. This substitution eliminates the need for tools and significantly reduces attachment time while maintaining reliable electrical contact through the plug contact's direct metallic connection to the printed circuit board.
Solution Approach 2:
The patent extracts the connecting clamp (screw-type or spring-loaded terminal) from the connection area and replaces it with a plug contact that is integrated into the housing structure. This extraction eliminates the complex clamping mechanism while preserving the essential function of establishing electrical contact, thereby simplifying the attachment process.
2Reliability
If a screw-type terminal or spring-loaded terminal is used for connection, then secure electrical contact is achieved, but the process becomes complex and requires precise alignment
Solution Approach 1:
The patent replaces the complex mechanical system of screw threads or spring clamps with a simple plug contact insertion mechanism. This substitution dramatically reduces the complexity of the connection process while maintaining secure electrical contact, as the plug contact directly engages with the printed circuit board contact area without requiring additional mechanical components.
Solution Approach 2:
The patent segments the connection system into distinct functional elements: the plug contact integrated in the housing and the corresponding contact area on the printed circuit board. This segmentation allows for independent optimization of each component and simplifies the overall connection process by eliminating the need for complex integrated clamping mechanisms.
3Reliability
If conductors are directly attached to the connection area, then electrical connection is established, but the process becomes difficult due to the small width of the housing
Solution Approach 1:
The patent introduces a plug contact as an intermediary element between the external connecting element and the internal printed circuit board. This intermediary allows conductors to be attached to the connecting element from the accessible broadside of the housing, rather than requiring direct attachment to the small connection area on the printed circuit board, thereby significantly improving ease of operation.
Solution Approach 2:
The patent changes the dimensional accessibility of the connection interface by moving it from the narrow width direction (where the connection area is located) to the broadside of the housing (where the connecting element is attached). This dimensional shift allows operators to work from the more accessible broadside, greatly improving ease of operation while maintaining reliable electrical connection.
