Cable-Wrapped Pull Strip for Stable Connector Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wire end connectors lack a fool-proof design for detachment, leading to potential damage and increased assembly time and labor costs due to improper pulling directions and assembly sequence.
Innovation Solution
The electrical connector features a pull strip with a winding portion that surrounds the cable when folded, allowing for perpendicular pulling and preventing damage, while enabling assembly after connector body attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional pull strip is used to facilitate detachment, then the user can apply pulling force to detach the connector, but the pull strip may be pulled in different directions causing damage to the connector and reducing service life
Solution Approach 1:
The pull strip is segmented into three functional portions: a connection portion connected to the connector body, a winding portion that can be folded around the cable, and a grip portion for user handling. This segmentation allows the winding portion to act as a buffer that guides the pulling force along the correct direction, preventing damage to the connector while maintaining ease of detachment.
Solution Approach 2:
The winding portion is preliminarily configured to be foldable around the cable before the actual detachment operation. This preliminary arrangement ensures that when the user pulls the grip portion, the force is automatically directed through the winding portion to the connection portion, preventing improper pulling directions before the damage can occur.
2Ease of manufacture
If the pull strip is assembled with the cable before being fastened to the housing, then the connector can be assembled, but the assembly process consumes time and increases labor costs
Solution Approach 1:
The connection portion is preliminarily integrated with the connector body during the connector housing assembly process, while the winding portion remains in a folded state around the cable. This allows the pull strip to be attached to the connector body first, and the cable can be inserted through the already-formed opening, eliminating the need to assemble the pull strip with the cable before fastening to the housing.
Solution Approach 2:
The winding portion is designed to be dynamic and flexible, allowing it to be folded around the cable after the connector body is assembled. This dynamic design enables the assembly sequence to be optimized: the connector body is assembled first, then the pull strip is attached, and finally the cable is routed through the opening formed by the folded winding portion, reducing overall assembly time and labor costs.

AI summary
An electrical connector includes a connector body, at least one cable, and a pull strip. The cable is electrically connected to the connector body. The pull strip includes a connection portion, a winding portion, and a grip portion. Two ends of the connection portion respectively connect the connector body and the winding portion. The winding portion is located between the connection portion and the grip portion. When the winding portion is in an unfolded state, the lengthwise direction of the winding portion is perpendicular to the lengthwise direction of the cable. When the winding portion is in a folded state, the winding portion surrounds the cable. The grip portion is configured to receive a pulling force.
