Retaining Frame for Plug Connectors with Multi-Level Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding frames for connectors struggle to simultaneously accommodate and securely integrate both control signal transmitting modules and high current transmitting connectors within a unified housing, due to differences in plug-in paths and mounting requirements.
Innovation Solution
A holding frame design featuring two mirror-image angle plates and a module carrier with parallel fastening surfaces, allowing for secure mounting of both connector modules and connectors at different levels, with circular and rectangular receptacles for plug connectors and modules respectively, and enabling over-plugging to accommodate varying sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a holding frame uses a unified receptacle design for all connector modules, then the structure is simple and easy to manufacture, but it cannot accommodate connectors with different plug-in paths and mounting requirements
Solution Approach 1:
The holding frame employs different receptacle designs for different connector types: circular receptacles for plug connectors and rectangular receptacles for connector modules. Each receptacle type is optimized for its specific connector category, allowing the holding frame to accommodate both high-current connectors and control signal modules with their different plug-in paths and mounting requirements.
2Volume of moving object
If connector modules and connectors are mounted at the same level, then the holding frame structure is compact, but over-plugging cannot be compensated for
Solution Approach 1:
The invention introduces a vertical dimension to the mounting arrangement by providing two different fastening levels: a first fastening level for plug connector modules and a second fastening level for plug connectors. This multi-level arrangement compensates for varying over-plugging dimensions while maintaining a compact overall structure, as the vertical stacking utilizes space more efficiently than horizontal expansion.
3Adaptability or versatility
If the holding frame integrates both control modules and power connectors, then it enables unified housing integration, but the mounting requirements and insertion forces become complex to manage
Solution Approach 1:
The holding frame is segmented into distinct functional zones with specialized receptacles: circular receptacles for plug connectors designed to handle high insertion forces, and rectangular receptacles for connector modules with different mounting requirements. This segmentation allows each zone to be optimized for its specific connector type, simplifying the overall integration into a unified housing while managing the complexity of different mounting requirements.

AI summary
The invention relates to a retaining frame (1) for retaining plug-connector modules (13) and/or plug connectors (12), said retaining frame (1) being provided for incorporation into a plug housing. The retaining frame (1) has a fixing surface (9) and the plug-connector modules (13) and/or the plug connectors (12) are held in the fixing surface (9). The plug-connector modules (13) and/or the plug connectors (12) can be mounted on different fixing planes (S, M). This allows plug connectors (12) and plug-connector modules (13) with differing mating heights to be installed in a plug-connector housing.
