Terminal Block External Jumpers for Reversible Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for electrical/electronic circuits, such as those on DIN rails and connection boxes, lack a safe and reversible external connection method to form multiple electrical connections, requiring internal screw-type or resilient spring means for wire retention and are complex in design.
Innovation Solution
A container terminal block with external continuity jumpers and a simplified internal design featuring insulating bodies with female seats for connectors and pins for secure electrical connections, eliminating the need for internal retention means and allowing biunique coding for precise connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal screw-type or resilient spring means are used for wire retention, then secure electrical connection is achieved, but device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent extracts the retention function from internal screw-type or spring means and relocates it to external continuity jumpers. The jumpers are positioned outside the terminal block housing, allowing wire retention and electrical connection without complex internal mechanisms. This extraction principle directly resolves the contradiction by eliminating internal complexity while maintaining secure connection through external jumper elements.
Solution Approach 2:
The continuity jumpers serve as intermediary elements that mediate between the wire connections and the electrical circuit. Instead of using direct internal screw or spring retention, the jumpers act as external mediators that provide both mechanical retention and electrical continuity, simplifying the internal structure while ensuring reliable connection.
2Reliability
If multiple internal retention mechanisms are provided, then reliable wire retention is achieved, but manufacturing cost and assembly time increase
Solution Approach 1:
The retention function is extracted from multiple internal mechanisms and consolidated into external continuity jumpers. This single external element performs the retention function that previously required multiple internal components, thereby reducing assembly time and manufacturing cost while maintaining reliable wire retention.
3Reliability
If internal continuity jumpers are used, then electrical connection is achieved, but access and modification become difficult
Solution Approach 1:
The continuity jumpers are extracted from the internal structure and positioned externally on the terminal block. This external positioning provides easy access for installation, modification, and maintenance of electrical connections, while still achieving reliable electrical continuity within the circuit.
