Connector Guide for Wire Harness Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face challenges in smooth fitting due to wire slack, leading to positional displacement and troublesome fitting operations when connecting counterparts, as the wires can swing and cause misalignment.
Innovation Solution
A connector design featuring a guide with a through portion that allows electrical wires to extend in both directions, acting as a shaft to prevent swinging and ensure proper alignment, along with a housing body and arm configuration that maintains wire stability and prevents misfitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical wires are drawn out from the connector with slack, then the wires can be routed through the electrical wire cover, but the connector may swing and become positionally displaced from the fittable position
Solution Approach 1:
The guide is provided in advance within the electrical wire cover to define the wire routing path. The guide includes a through portion that预先 (in advance) establishes the correct position and direction for wire passage, preventing the connector from swinging or becoming displaced during the fitting process.
Solution Approach 2:
The guide acts as an intermediary component between the electrical wires and the electrical wire cover. It mediates the interaction by providing a structured through portion that guides the wires while simultaneously serving as a positional reference that prevents connector displacement.
2Ease of operation
If the connector is allowed to swing freely, then ease of movement is improved, but fitting accuracy with the counterpart connector deteriorates
Solution Approach 1:
The guide structure is预先 (in advance) built into the electrical wire cover to define the exact fitting position. This preliminary structural arrangement ensures that when the connector is brought for fitting, it automatically aligns with the counterpart connector through the guide's geometric constraints, eliminating the need for manual positioning adjustments.
3Manufacturing precision
If a guide structure is added to prevent connector swinging, then fitting accuracy is improved, but device complexity increases
Solution Approach 1:
The guide is merged with the electrical wire cover as an integrated structure. The through portion of the guide is formed as part of the electrical wire cover's body, combining two functions (wire routing and positioning guidance) into a single component, thereby improving fitting accuracy without significantly increasing overall device complexity.
Solution Approach 2:
The electrical wire cover is designed to serve multiple functions: it protects the electrical wires, provides routing guidance through the guide structure, and acts as a positioning reference for connector fitting. This multi-functionality reduces the need for separate components, maintaining simplicity while achieving high fitting accuracy.
