Multi-Pin Connector Cover with Offset Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing covering hoods for multi-pole plug elements do not effectively manage and protect cables from dirt, dust, and moisture, particularly in spatially limited installations, and complicate cable routing and assembly.
Innovation Solution
A two-part covering hood design with offset openings that guide cables in a targeted manner, featuring sliding guide areas for secure assembly, a cable bundling element, and a design that mimics additional plug elements for aesthetic integration, preventing dust ingress and damage to cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a covering hood is used to protect cables from dirt and dust, then protection against contaminants is improved, but cable routing becomes complicated and assembly becomes difficult
Solution Approach 1:
The covering hood is divided into a first housing part and a second housing part that can be assembled separately. The first housing part is assembled on the connector element first, then cables are routed through openings, and finally the second housing part is mounted to complete the assembly. This segmentation simplifies both cable routing and assembly operations.
Solution Approach 2:
The patent introduces openings that extend through both housing parts in a direction transverse to the longitudinal axis of the connector element. This creates a new dimensional path for cable routing that bypasses the complicated routing through the connector element slots, making cable management easier while maintaining protection.
2Strength
If the covering hood is designed as a single integrated unit, then structural strength is improved, but handling and assembly become more difficult
Solution Approach 1:
The covering hood is segmented into a first housing part and a second housing part. The first housing part can be handled and assembled separately on the connector element, making the overall assembly process easier. The two parts are then connected to form the complete covering hood, maintaining structural strength while improving handling.
Solution Approach 2:
The first and second housing parts are designed to nest together, with the second housing part mounted on the first housing part. This nested structure allows separate handling of smaller components during assembly while forming a strong integrated unit when combined.
3Ease of operation
If the openings are arranged directly one above the other, then cable routing is simplified, but the visual impression is poor and dust ingress is facilitated
Solution Approach 1:
The openings in the first and second housing parts are arranged asymmetrically relative to each other. The opening in the first housing part is offset from the opening in the second housing part, creating a staggered configuration. This asymmetric arrangement prevents direct alignment that would facilitate dust ingress while maintaining effective cable routing capability.
Solution Approach 2:
The second housing part acts as an intermediary barrier between the external environment and the connector element slots. By positioning the opening in the second housing part offset from the opening in the first housing part, the second housing part effectively blocks the direct path for dust and dirt to reach the slots, while still allowing cables to pass through both openings.
