Plug-In Connector Frame for Blind Mating and Hermetic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connectors face challenges in achieving reliable and faultless blind plugging and hermetic sealing against external media, especially in situations where clear visibility of the mating plug is obstructed, leading to potential damage and inefficiencies in mounting and sealing processes.
Innovation Solution
A plastic frame with a specific geometry is used to accommodate standard modules and provide sealing, combined with a potting frame or sleeve housing for sealing the wiring space, allowing for adaptable and secure mounting on various housing types, with a plugging contour designed for correct orientation and sealing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plug-in connectors are enclosed in housings to achieve hermetic sealing against external media, then sealing performance is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The frame is designed with a universal sealing geometry that can be used across different plug-in connector configurations and housing types. The same frame design with integrated sealing surfaces and potting compound accommodation serves multiple sealing functions, eliminating the need for specially adapted housings for each application while maintaining hermetic sealing performance.
Solution Approach 2:
The sealing function is merged into the frame structure itself through integrated sealing surfaces and the combination of the frame with potting compound or sleeve housing. This consolidation eliminates separate sealing components and reduces overall structural complexity while achieving hermetic sealing.
2Reliability
If specially adapted housings are designed for blind plugging applications, then mounting reliability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The frame provides universal mounting functionality for blind plugging applications through standardized plugging contours and geometric features that work across different configurations. This universal design allows the same frame to be used in various mounting scenarios without requiring specially adapted housings, reducing manufacturing costs while maintaining mounting reliability.
3Ease of manufacture
If standard modules are used in plug-in connectors, then ease of manufacture and cost-effectiveness are improved, but adaptability to different housing types may be limited
Solution Approach 1:
The frame acts as a universal adapter that enables standard modules to be adapted to different housing types. The frame's standardized interface and geometric design allow it to interface with various housing configurations while maintaining the benefits of using standard modules, thus achieving both cost-effectiveness and adaptability.
