Connection arrangement for the connection of two switchgear cabinet frameworks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection assemblies for switchgear cabinet racks require precise alignment of profile frames for modular connector installation, occupying significant installation space and being cumbersome to handle.
Innovation Solution
The modular connector is designed to be fixed to parallel fastening flanges on the profile frames, allowing for loose interconnection and alignment, with chamfered sealing ribs and a slip-on seal for secure seating, and optional centering contours for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the modular connector is fixed by means of two profile sides that are aligned perpendicular to a sealing plane, then the connection assembly achieves secure fixation, but it requires exact alignment of profile frames prior to mounting, increasing installation complexity and time
Solution Approach 1:
The patent applies preliminary action by providing pre-formed fastening flanges that are chamfered from the sealing ribs, which are already positioned and prepared on the profile frames before the modular connector is installed. This pre-positioning eliminates the need for exact alignment during installation, as the fastening flanges guide the modular connector into place. The sealing ribs are also pre-formed with chamfers to facilitate the seating of the modular connector, thereby reducing installation time while maintaining secure fixation.
Solution Approach 2:
The patent introduces an intermediary element - the fastening flange - that mediates between the profile frame and the modular connector. The fastening flange serves as an intermediate structure that is easily attachable to the profile frame and provides a convenient interface for mounting the modular connector. This intermediary component simplifies the connection process by decoupling the alignment requirements, allowing the modular connector to be fixed securely without demanding exact alignment of the profile frames.
2Volume of moving object
If the modular connector is installed in a space-saving manner in a receptacle formed between profile frames, then installation space is minimized, but the profile frames must be exactly aligned to make corresponding bolt passageways flush, increasing handling difficulty
Solution Approach 1:
The fastening flanges are pre-formed and chamfered from the sealing ribs, positioning them in advance to guide the modular connector into the receptacle space. This pre-positioning allows the modular connector to be installed in a space-saving manner within the receptacle formed between the profile frames without requiring exact alignment of the profile frames during installation.
Solution Approach 2:
The fastening flange acts as an intermediary that facilitates the connection of the modular connector to the profile frames in a space-constrained environment. By providing a pre-formed attachment interface, the fastening flange enables easy handling and installation of the modular connector within the limited space of the receptacle, eliminating the need for precise alignment of bolt passageways.
3Reliability
If the profile frames are required to be exactly aligned for modular connector installation, then secure connection is achieved, but the connection assembly becomes cumbersome to handle and install
Solution Approach 1:
The sealing ribs are pre-formed with chamfers that extend from the outer sealing edges toward the fastening flanges. This preliminary shaping of the sealing ribs creates a guided pathway that automatically aligns the modular connector with the profile frames during installation, eliminating the need for manual alignment operations while ensuring secure connection.
Solution Approach 2:
The fastening flange serves as an intermediary component that simplifies the alignment process. By providing a pre-positioned attachment interface on the profile frame, the fastening flange mediates between the profile frame structure and the modular connector, enabling secure connection without requiring complex alignment procedures.

AI summary
A connection arrangement having a first and a second switchgear cabinet framework which each have a rectangular, lateral profile frame composed of two vertical struts and two horizontal struts, wherein the profile frames are connected to one another via an aligning connector, wherein the switchgear cabinet frameworks adjoin one another via outer sealing edges of the profile frames, wherein the outer sealing edges are arranged on the respective free end of a sealing web of the profile frame, wherein a fastening flange is bent off from each of the sealing webs so as to be set back from the outer sealing edge, with the result that the opposite fastening flanges delimit between them a receptacle for an aligning connector for the profile frames, which receptacle is further delimited by the adjoining sealing webs and, where appropriate, a sealing element arranged between the sealing webs, and wherein an aligning connector is arranged in the receptacle and is secured to the opposite fastening flanges.
