Solution Overview
Problem
Existing connection assemblies for electrical wires lack a stable and efficient mechanism to securely connect multiple terminals while allowing easy assembly and disassembly of electrical wires without requiring tools.
Innovation Solution
A connection assembly with a plurality of connection terminals featuring a housing part, contact element, and spring element, where the terminals are guided by guide webs in an outer housing, allowing easy assembly and providing mechanical stability, and a detachment element for automatic release of the clamping leg, enabling tool-free attachment and detachment of electrical wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connection terminals are arranged in a row and inserted into an outer housing without guide devices, then the assembly process is simple, but the mechanical stability and alignment of the connection block deteriorates
Solution Approach 1:
Guide webs are introduced as intermediary elements between the housing parts and the outer housing. These guide webs act as mediators that facilitate the insertion process while simultaneously ensuring proper alignment and mechanical stability of the connection block, resolving the contradiction between assembly simplicity and structural stability.
Solution Approach 2:
The guide webs extend in the assembly direction (third dimension) to provide guidance and stabilization. By adding this dimensional element, the housing parts are guided during insertion, ensuring accurate positioning and stable assembly without complicating the basic row arrangement structure.
2Reliability
If a tool is used to move the clamping leg into the release position, then the clamping leg can be reliably actuated, but the ease of operation for attaching and detaching electrical wires deteriorates
Solution Approach 1:
The detachment element is designed to be actuated directly by the electrical wire itself during the insertion process. The wire's movement automatically triggers the detachment element to move the clamping leg into the release position, eliminating the need for external tools and enabling tool-free operation while maintaining reliable actuation.
Solution Approach 2:
The detachment element is pre-configured with a detachment leg that interacts with the electrical wire before the wire is fully inserted. This preliminary arrangement ensures that as the wire is inserted, it automatically activates the detachment element, which then releases the clamping leg in advance, facilitating smooth and tool-free wire attachment.
3Ease of operation
If the clamping leg is held in the release position without a locking mechanism, then the ease of operation for wire insertion is improved, but the reliability of maintaining the release position deteriorates
Solution Approach 1:
The locking element is designed to automatically engage with the detachment element when the clamping leg is in the release position. This preliminary locking action prevents the clamping leg from accidentally moving away from the release position during wire insertion, ensuring the release position is maintained reliably without requiring continuous external force or complex mechanisms.
