Connector Seal Structure With Pressed Tab Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face challenges in ensuring satisfactory sealability due to insufficient surface pressure between the male terminal and the sealing portion, which affects the overall sealing performance.
Innovation Solution
A connector design featuring a male terminal with a tab, a housing with a sealing space, a sealing portion that contacts the tab, and a pressing portion that compresses the sealing portion within the sealing space, enhancing the surface pressure and sealability by sandwiching the sealing portion between the housing end surface and the pressing portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sealing structure is used without a pressing portion, then the device complexity is reduced, but the sealability between the male terminal and sealing portion is insufficient
Solution Approach 1:
The pressing portion is integrated into the housing structure, merging the sealing function with the housing's structural elements. The housing simultaneously provides structural support and sealing pressure through its design, eliminating the need for separate pressing components while ensuring adequate sealability between the male terminal and sealing portion.
Solution Approach 2:
The housing serves multiple functions: it provides structural support, contains the sealing space, and through the pressing portion design, applies compression force to ensure sealing. This multi-functionality reduces overall device complexity while maintaining reliable sealability.
2Reliability
If the sealing portion is compressed to enhance surface pressure, then the sealability is improved, but the sealing portion may deform excessively
Solution Approach 1:
The pressing portion is designed to apply compression force at specific localized areas where sealing is most critical, rather than uniformly compressing the entire sealing portion. This targeted approach enhances surface pressure and sealability at the interface between the male terminal and sealing portion while minimizing overall deformation of the sealing portion.
Solution Approach 2:
The pressing portion applies sufficient compression force to achieve adequate sealability without excessive force that would cause harmful deformation. The design balances the compression level to provide just enough pressure to ensure sealing performance while maintaining the structural integrity and shape of the sealing portion.
