Holding Frame With Integrated Projections For Plug Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding frames for plug connector modules are costly and complex to produce due to the need for additional steps like inserting limiting posts, which also limit the flexibility in earthing contact positioning, and may compromise mechanical stability during installation.
Innovation Solution
A holding frame design with two articulated halves and laterally closed recesses in the side parts, featuring projections and recesses in the fastening sections to prevent lateral displacement, allowing for simplified production and flexible earthing contact placement without requiring special tools for assembly or disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If limiting posts are inserted to prevent axial displacement of side parts, then mechanical stability is improved, but device complexity and production cost increase
Solution Approach 1:
The patent removes the limiting posts from the structure entirely. Instead of inserting separate posts to prevent axial displacement, the design uses the fastening ends themselves with integrated projections that perform the same function, thereby simplifying the device and reducing production steps while maintaining mechanical stability
Solution Approach 2:
The patent combines the function of limiting posts with the fastening ends. The projections at the fastening ends serve dual purposes: providing the fastening function and simultaneously preventing axial displacement of side parts, eliminating the need for separate limiting posts
2Stability of the object's composition
If limiting posts are used to prevent axial displacement, then mechanical stability is improved, but production time and cost increase due to additional insertion steps
Solution Approach 1:
The projections are pre-formed as integral parts of the fastening ends during the molding process. This preliminary action eliminates the need for subsequent insertion steps, allowing the holding frame to be produced more efficiently while still providing the necessary mechanical stability
Solution Approach 2:
By removing the limiting posts entirely and using integrated projections instead, the patent eliminates the additional insertion step from the production process, thereby improving production efficiency and reducing manufacturing time
3Device complexity
If the holding frame uses a simple design without additional components, then production is simplified, but axial displacement of side parts cannot be prevented
Solution Approach 1:
The patent merges the fastening function with the displacement prevention function into a single integrated structure. The projections at the fastening ends simultaneously provide fastening capability and prevent axial displacement, achieving both simplicity and mechanical stability without requiring separate components

AI summary
Provided is a holding frame for holding plug connector modules and for installing in plug connector casings or for screwing onto wall surfaces, wherein the plug connector modules are inserted into the holding frame and a holding arrangement on the plug connector modules cooperate with recesses provided on opposite side parts of the holding frame. Also, to allow simplified and/or less cost-intensive production with additional flexibility regarding the positioning or omission of earthing contacts, without compromising safe handling of the holding frame, one frame half has a projection in at least one fastening section, which protrudes in the direction of the other frame half and which engages with a recess in the fastening section of the other frame half in such a way that any lateral displacement of the side parts is prevented.
