Connector Housing Hole Layout for Cap Attachment and Water Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector units face complexity in structure due to the need for multiple drain passages and attachment holes to discharge water and attach a cap, limiting their orientation and complicating the design.
Innovation Solution
A connector unit with a front plate portion featuring two or more through-holes positioned on diagonal lines of a rectangular surrounding the opening, one serving as a cap attachment hole and the other as a drain hole, allowing for a simple structure that can be oriented in various directions while maintaining functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple drain passages and attachment holes are formed in the front plate portion, then water discharge functionality is improved, but device complexity increases
Solution Approach 1:
The through-holes in the front plate portion are designed to serve dual functions: they act as attachment holes for securing the cap and as drain holes for water discharge. This multi-functionality eliminates the need for separate structures, reducing device complexity while maintaining both cap attachment and water discharge functionalities.
Solution Approach 2:
The invention merges the cap attachment hole and drain hole into a single through-hole structure. By combining these two previously separate functions into one integrated component, the overall structure is simplified while achieving both objectives of securing the cap and enabling water discharge.
2Adaptability or versatility
If multiple attachment holes are formed for different orientations, then adaptability to various positions is improved, but device complexity increases
Solution Approach 1:
The through-holes are positioned and sized to serve as attachment holes regardless of the connector unit's orientation. The diagonal positioning ensures that in any orientation (horizontal or vertical), there is always an upper through-hole suitable for cap attachment, providing orientation-independent functionality without requiring multiple sets of holes.
Solution Approach 2:
The through-holes are positioned asymmetrically on diagonal lines of the rectangular surrounding the opening portion. This asymmetric diagonal arrangement ensures that regardless of how the connector unit is oriented, one through-hole will always be positioned above the opening portion, enabling universal cap attachment across different orientations.

AI summary
This connector unit includes a connector housing. The connector housing has a front-surface plate part and two or more through-holes penetrating the front-surface plate part to be connected to the inside of the connector housing. In the front-surface plate part, two through-holes of the two or more through-holes are disposed at positions of two opposing apexes of a rectangle surrounding an opening portion. When the connector unit is installed, one through-hole of the two through-holes is positioned above the opening portion to serve as a cap attachment hole, and the other through-hole of the two through-holes is positioned below the opening portion to serve as a water drain hole.
