Split-Hood Connector Assembly Without Screw Hole Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector configurations require special means for attaching the hood, necessitating additional work for forming screw holes in the fixing target.
Innovation Solution
A connector design featuring a hood composed of two split bodies that can be easily attached to the housing using through holes, eliminating the need for special attachment means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used for attaching and fixing the hood, then the hood can be securely fixed to the connector terminal, but additional work for forming screw holes is required in the fixing target
Solution Approach 1:
The invention extracts the attachment function from the housing and relocates it to the hood itself. The hood includes a hood attachment protrusion that fits into a hood attachment hole formed in the terminal, separating the attachment mechanism from the housing structure. This allows the hood to be attached without requiring screw holes in the housing, reducing manufacturing complexity while maintaining secure fixation.
Solution Approach 2:
The hood attachment protrusion and hood attachment hole act as an intermediary attachment mechanism between the hood and terminal. Instead of directly screwing the hood to the housing, this intermediate attachment structure enables the hood to be fixed to the terminal first, which is then integrated with the housing assembly, eliminating the need for additional screw holes in the housing.
2Ease of operation
If special screw holes are formed in the fixing target for attaching the hood, then the hood can be attached, but the attachment process becomes more complex and time-consuming
Solution Approach 1:
The hood attachment protrusion is pre-formed on the hood during hood manufacturing, and the hood attachment hole is pre-formed in the terminal during terminal manufacturing. This preliminary preparation of attachment features eliminates the need for on-site screw hole formation during assembly, significantly reducing attachment time and simplifying the operation.
Solution Approach 2:
The invention merges the hood attachment function with the existing terminal structure by forming the hood attachment hole in the terminal. This integration allows the hood to be attached to the terminal assembly as a unit, combining multiple functions (terminal attachment and hood fixation) into a single structural feature, thereby simplifying the overall attachment process.

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.
