Connector Wire Tape Structure for Displacement-Resistant Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric wires with connectors require an increased tape width to prevent displacement, leading to an increase in the number of work steps and tape usage.
Innovation Solution
The electric wire with connector features a covering portion formed by a tape with a first winding portion around the connector under-neck, a second winding portion around the electric wire, a cross-winding portion intersecting the first and second portions, and a wrap-winding portion over or under the cross-winding portion, using half-wrap winding to prevent displacement.

Engineering Contradiction Analysis
1Reliability
If the wrap width of the tape is increased to 2/3 or more of the tape width to prevent displacement, then the tape displacement is prevented, but the number of work steps and the amount of tape used increase
Solution Approach 1:
The tape winding process is segmented into three distinct portions: a first winding portion that winds the tape around the connector under-neck, a second winding portion that winds the tape around the electric wire or exterior material, and a cross-winding portion that stretches the tape between these two portions to intersect the electric wire. This segmentation allows each portion to perform its specific function with optimized tape width, preventing the need to increase the overall wrap width to 2/3 or more of the tape width.
Solution Approach 2:
The invention introduces a cross-winding dimension by stretching the tape between the first and second winding portions to intersect the electric wire. This adds a new dimensional approach to securing the tape, rather than relying solely on increasing the wrap width in the original winding direction. The cross-winding portion creates a three-dimensional tape configuration that enhances displacement prevention without requiring increased tape width.
2Reliability
If the wrap width of the tape is increased to 2/3 or more of the tape width to prevent displacement, then the tape displacement is prevented, but the amount of tape used increases
Solution Approach 1:
By dividing the tape into functional segments (first winding portion, second winding portion, and cross-winding portion), each segment can use the minimum necessary tape width for its specific function. The first winding portion secures the under-neck, the second winding portion secures the electric wire, and the cross-winding portion provides additional anchoring. This segmentation eliminates the need to use excessive tape width throughout the entire covering portion.
Solution Approach 2:
Different portions of the tape are designed with different functions and local characteristics. The first winding portion has a width suitable for covering the under-neck, the second winding portion has a width suitable for covering the electric wire, and the cross-winding portion is stretched to intersect the wire. This local quality optimization ensures that tape is used efficiently in each specific location rather than uniformly increasing the width throughout.

AI summary
An electric wire with connector includes a connector, an electric wire inserted into an under-neck portion of the connector, and a covering portion formed by a tape wound around the under-neck portion and the electric wire. The covering portion includes a first winding portion in which the tape is wound around the under-neck portion, a second winding portion in which the tape is wound around the electric wire or an exterior material through which the electric wire is inserted, a cross-winding portion in which the tape is stretched between the first winding portion and the second winding portion to intersect the electric wire, and a wrap-winding portion in which the tape is wrap-wound over or under the cross-winding portion.
