Wire Plug-in Aid Sleeve Structure for Multi-Strand Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire connection terminals with larger inlets allow dust and water ingress and cause conductive wires to deflect, leading to poor contact and insecurity, especially when multi-strand wires with smaller diameters are used, requiring cumbersome handling to plug in forked conductor ends.
Innovation Solution
A wire plug-in aid sleeve structure with a recessed guide channel and wire collection section that gradually binds the forked conductor end, featuring a guide hole with tapered sections and a display face for character encoding, simplifying the plug-in process and enhancing recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wire inlet diameter is made obviously larger than the conductive wire diameter to facilitate easy plugging, then the ease of operation is improved, but the reliability deteriorates due to dust and water intrusion affecting electro-conductive performance
Solution Approach 1:
The guide sleeve is nested within the wire inlet, creating a layered structure where the smaller guide sleeve fits inside the larger wire inlet. This allows the conductive wire to pass through the guide sleeve's guiding portion which provides precise alignment and protection, while the guide sleeve itself is contained within the wire inlet structure, thus maintaining both ease of operation and reliability
Solution Approach 2:
The guide sleeve acts as an intermediary component between the conductive wire and the wire inlet. It provides a guiding portion that aligns and protects the wire during insertion, ensuring reliable electro-conductive contact while facilitating easy plugging operations. The guide sleeve mediates the interaction between the wire and inlet, preventing direct exposure to dust and water
2Ease of operation
If the wire inlet diameter is made obviously larger than the conductive wire diameter to facilitate easy plugging, then the ease of operation is improved, but the stability deteriorates due to wire deflection and swinging under external force
Solution Approach 1:
The guide sleeve is nested within the wire inlet, creating a layered structure where the smaller guide sleeve fits inside the larger wire inlet. This allows the conductive wire to pass through the guide sleeve's guiding portion which provides precise alignment and protection, while the guide sleeve itself is contained within the wire inlet structure, thus maintaining both ease of operation and reliability

It provides a guiding portion that aligns and protects the wire during insertion, ensuring reliable electro-conductive contact while facilitating easy plugging operations. The guide sleeve mediates the interaction between the wire and inlet, preventing direct exposure to dust and water
3Stability of the object's composition
If the guide hole diameter is made smaller to match the conductive wire diameter to prevent deflection, then the stability is improved, but the ease of operation deteriorates as multi-strand wire forked ends become difficult to plug in
Solution Approach 1:
The guide sleeve is divided into distinct functional sections: a guiding portion with a smaller diameter that matches the wire diameter to provide stability and prevent deflection, and an enlarged portion with a larger diameter that facilitates easy insertion of multi-strand wire forked ends. This segmentation allows each section to perform its specific function optimally
Solution Approach 2:
Different sections of the guide sleeve have different diameters tailored to specific functional requirements. The guiding portion has a smaller diameter for stability and precise alignment, while the enlarged portion has a larger diameter for ease of insertion. This local variation in quality (diameter) allows the single component to satisfy both contradictory requirements

AI summary
The middle section and the tail section are mounted in a wire inlet of a terminal device. The aid sleeve is formed with an internal guide hole. A wire collection section is disposed on one side of the head section distal from the middle section. A recessed guide channel is disposed on one side of the wire collection section proximal to the guide hole. The recessed guide channel includes two lateral outer arched channels with larger curvature radius. The two lateral outer arched channels gradually extend toward a middle bottom face to form an inner arched channel with smaller curvature radius. The recessed guide channel can gradually bind the forked conductor end section of a multi-strand conductive wire, whereby the wire can be quickly plugged into the guide hole.
