Wire Connector with Protecting Portion to Prevent Accidental Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire connectors require multiple types to support both wire branching and extension, and often necessitate wire cutting, which can lead to accidental cutting of extension wires during the cutting operation.
Innovation Solution
A wire connector design that includes a wire holder with specific end faces and holding portions for both main and extension wires, featuring openings for easy insertion and a protecting portion around the extension wire to prevent accidental cutting, allowing for both branching and extension without separate connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single wire connector is used to support both wire branching and wire extension, then the number of connector types is reduced and versatility is improved, but the risk of accidental cutting of extension wires during cutting operations increases
Solution Approach 1:
The protecting portion acts as an intermediary element between the cutting tool and the extension wire. It physically intervenes to prevent the cutting tool from reaching the extension wire, thereby mediating the interaction between the operator's cutting action and the wire to be protected.
Solution Approach 2:
The protecting portion is positioned in advance to counteract the potential harmful action of accidental cutting. By pre-placing this protective structure, the system prepares a counter-measure before the cutting operation occurs, preventing the harmful effect rather than responding to it afterward.
2Ease of operation
If openings are provided in the wire holder for easy wire insertion, then ease of operation is improved, but the risk of wire misalignment or incorrect insertion increases
Solution Approach 1:
The wire holder structure provides self-aligning features where the opening geometry and surrounding structures guide the wire into the correct position automatically during insertion. The design enables the wire to self-correct its alignment as it passes through the opening, reducing reliance on operator precision.
Solution Approach 2:
The opening structure serves as an intermediary guide that mediates between the operator's insertion action and the wire. It provides a controlled path that ensures proper wire positioning while maintaining ease of insertion, acting as a guiding mechanism between the external action and the internal wire placement.

AI summary
A wire connector is described that suppresses the cutting of wires accidentally. The wire connector 1 includes a wire holder 6 that holds at least two wires, a contact 7A that electrically connects the two wires and a body 4 that holds the wire holder. The wire holder 6 includes first and second end faces 24 and 26, and a wire holding portion 25 that includes first and second holding portions 32, 33, 34 and 36. On the first end face 24, at portions of circumferential edge portions of the openings 34c and 36d of the second holding portions 34 and 36, protecting portions 23 that project from the first end face 24 and protect the wires are provided.
