Split Hood Connector Structure for Easy Cable Pull-Out Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector designs require additional work to form special screw holes in the fixing target for attaching and fixing the hood, complicating the installation process.
Innovation Solution
A connector design featuring a housing with through holes for attaching a hood composed of two split bodies, which are secured using bundling bands, allowing easy attachment without additional means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to attach the hood to the connector, then the hood can be securely fixed, but additional screw holes must be formed in the connector body increasing manufacturing complexity
Solution Approach 1:
The attaching portion is integrated into the hood body as a unified structure. The hood includes a body portion and an attaching portion that works together as a single component, eliminating the need for separate fastening mechanisms and reducing the number of parts that need to be manufactured and assembled.
Solution Approach 2:
The attaching portion serves multiple functions: it provides mechanical attachment to the connector body, ensures proper positioning during assembly, and maintains electrical isolation. This multi-functional design eliminates the need for separate positioning features and fastening elements.
2Device complexity
If a unified hood structure is used, then the structure is simple, but it cannot provide both straight and angled cable pull-out paths
Solution Approach 1:
The hood is divided into functional zones within the single body: a straight pull-out hole for vertical cable routing and an angled pull-out hole for horizontal cable routing. This segmentation of functions within a unified structure allows multiple cable configurations without requiring separate hood components.

AI summary
A module is composed of a terminal that is attached to a cable and an insulator that accommodates the terminal. The insulator includes two spring pieces and two protrusions that are formed on the two respective spring pieces. A housing has through holes on mutually opposed positions on respective side walls surrounding an accommodation space. The module is accommodated in the accommodation space in a manner such that the two protrusions thereof are fitted from an inside into the respective through holes. A hood is composed of two split bodies. The hood can be fixed on the housing in a manner such that projecting portions of the split bodies are fitted from an outside into the respective through holes and the two split bodies are coupled to each other with a coupling means.
