Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiring terminals with open-type bodies deform under resilient force, compromising structural strength and stability, and generate excess residues and waste during production, increasing costs.
Innovation Solution
A clamping wire structure featuring a close-type insertion base with a conductive frame and a V-shaped spring, where the spring is inserted into an insertion space formed by the frame, enhancing stability and reducing material usage by forming the components directly from conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an open-type terminal block is used, then the assembly process is simpler, but the structural strength and stability are compromised under resilient force
Solution Approach 1:
The patent merges the insertion base and spring into a single integrated component formed from one conductor. The insertion base includes forming portions that directly create the spring structure, eliminating the need for separate assembly steps while maintaining structural integrity under resilient force.
Solution Approach 2:
The conductor is segmented into functional portions: an insertion base portion that forms the frame structure, and spring portions that provide resilient force. This segmentation allows each part to perform its specific function while being manufactured as a single piece, resolving the contradiction between assembly simplicity and structural strength.
2Ease of operation
If conventional bent structures are produced, then the clamping function is achieved, but more residues and waste are generated during production
Solution Approach 1:
The patent changes the manufacturing parameter from conventional bending processes to a direct forming process. The conductor is directly formed into the final shape with integrated spring portions, eliminating the need for multiple bending operations and reducing production residues and waste while maintaining the clamping function.
3Ease of manufacture
If separate components are used for insertion base and spring, then manufacturing flexibility is improved, but material usage increases
Solution Approach 1:
The patent combines the insertion base and spring into a single integrated component made from one conductor, eliminating the material that would be required for separate components, fasteners, and assembly fixtures. This merging reduces total material usage while maintaining manufacturing flexibility through the forming process.

Function Achieved in This Case
The close-type frame design improves structural strength and reduces production costs by allowing greater resilient force without deformation and minimizing material usage, facilitating easier assembly and reduced waste.
Implementation Method 1
The adjustment portion is in resilient contact with the contact section by a resilient restoring force of the spring

AI summary
A clamping wire structure of a terminal block includes an insertion base (10) and a spring (20). The insertion base (10) includes an insertion slot (12), a contact section (13), a linking piece (14), a first connection portion (15), an extension element (16), a connection slot (161), and a conductive pin (17). The insertion base (10) bends, so that the insertion slot (12) is positioned correspondingly above the extension element (16), and the linking piece (14) is inserted in the connection slot (161) to allow the insertion slot (12) and the extension element (16) to surroundingly form an insertion space (100). The spring (20) is bent into a V-shaped spring. The spring (20) is inserted in the insertion space (100).
