Retaining Frame for Plug Connectors with Integrated Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding frames for plug-connector modules and plug connectors are complex to produce and assemble, especially when integrating modules for high currents, due to the need for multiple elements and different fastening planes.
Innovation Solution
A holding frame composed of two mirror-inverted side parts and a fixing element, which forms a stable fastening surface for plug connectors and a receiving region for modules, allowing for simple assembly and integration into a plug-connector housing with a screw-connected design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple elements and different fastening planes are used to accommodate both plug connectors and plug-connector modules, then both types of connectors can be integrated, but the production and assembly complexity increases
Solution Approach 1:
The patent combines the fastening functions for both plug connectors and plug-connector modules into a single integrated fastening plane. The holding frame structure integrates receiving spaces for both connector types at the same fastening level, eliminating the need for multiple fastening planes and reducing assembly complexity while maintaining the ability to accommodate both connector types.
Solution Approach 2:
The holding frame is designed with universal receiving spaces that can accommodate both plug connectors and plug-connector modules through a single fastening interface. The frame structure provides multi-functional capability by supporting different connector types with unified fastening geometry, reducing the need for specialized mounting arrangements.
2Stability of the object's composition
If multiple elements are used to form the holding frame, then structural stability can be ensured, but the number of parts and assembly steps increases
Solution Approach 1:
The patent merges multiple frame elements into a single integrated holding frame structure. This unified structure maintains structural stability through its geometric design and material properties while reducing the total number of parts from multiple separate elements to one monolithic component, thereby simplifying assembly.
Solution Approach 2:
While the frame is integrated, the design incorporates internal geometric segmentation through the arrangement of receiving spaces and structural ribs that provide stability. The segmentation is achieved within the single piece through form rather than separate components, maintaining stability without increasing part count.

AI summary
A retaining frame for retaining plug-connector modules and/or plug connectors for installation in a plug connector housing, has two side parts each with at least one surface and at least one frame element designed to be fitted together to form the retaining frame. The surfaces of the side parts, once joined together, form a fastening surface having at least one recess for receiving a plug connector. The frame elements of the side parts of the retaining frame, once joined together, are spaced apart from one another and form at least one receiving region for receiving the plug-connector modules. On the fastening surface, at least one fixing element is provided, which can be fixed there in such a way that the side parts joined together to form the retaining frame are fixed, and that a plug connector accommodated in the recess is also axially fixed in the retaining frame.
