Connector Housing Assembly With Retained Panel Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for electrical equipment suffer from gaps that allow foreign objects and water ingress, leading to malfunctions, and current sealing members are prone to fall off during transportation.
Innovation Solution
A housing assembly with an insulation housing and a fixed sealing structure, featuring a flange portion and retention features to securely attach a sealing member that abuts against the mounting panel, preventing ingress and ensuring the sealing member does not fall off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing member is provided on the connector to seal the gap, then sealing performance is improved, but the sealing member is prone to fall off during transportation
Solution Approach 1:
The sealing member is integrated with the insulation housing through a retention groove structure. The retention groove is formed directly on the insulation housing, and the sealing member is embedded within this groove, merging the sealing function with the housing structure to prevent detachment during transportation while maintaining sealing effectiveness.
2Ease of manufacture
If there is a gap between the mounting panel and the connector, then installation is simpler, but foreign objects and water can easily enter causing malfunctions
Solution Approach 1:
An elastic sealing member is used to bridge the gap between the connector and mounting panel. The elastic material allows the sealing member to deform and conform to the interface, effectively sealing the gap to prevent foreign object and water ingress while maintaining installation simplicity.
3Object-affected harmful factors
If a sealing member is added to seal the gap, then protection against foreign objects is improved, but the device complexity increases
Solution Approach 1:
The retention groove for the sealing member is formed directly on the insulation housing, merging the retention function with the existing housing structure. This integration approach provides effective sealing and protection against foreign objects without significantly increasing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively seals the gap between the connector and mounting panel, preventing foreign objects and water ingress while maintaining the sealing member's integrity during transportation and installation.
Implementation Method 1
The sealing structure is elastic and abuts against the mounting panel to seal a gap between the insulation housing and the mounting panel

AI summary
A housing assembly of a connector for installing to a mounting panel includes an insulation housing and a sealing structure. The insulation housing has a housing body extending axially and a flange portion extending radially outward from an outer wall of the housing body. The sealing structure is fixedly retained on a side of the flange portion facing the mounting panel. The sealing structure is elastic and abuts against the mounting panel to seal a gap between the insulation housing and the mounting panel.
