Pivot Mounting Device for Electric Plug Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for electric plug couplings require precise manufacturing tolerances to ensure reliable locking against tilting and easy movement into an operational position, which increases manufacturing expenses.
Innovation Solution
The mounting device uses parallel guide slots with slot constrictions and a tilt locking element to separate the functions of locking and unlocking, allowing the coupling receptacle to be securely locked in the installation position without damaging the components, and easily pivoted into the operational position by overcoming a predetermined threshold force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If precise manufacturing tolerances are used for latch elements and pivotal mounting, then reliable locking force is achieved, but manufacturing expense increases
Solution Approach 1:
The mounting device is divided into functionally independent components: the coupling receptacle with its latch element, the mounting component with guide slots and slot constrictions, and the door handle carrier with tilt locking. This segmentation allows each component to be manufactured with standard tolerances while achieving reliable overall performance through their coordinated interaction.
Solution Approach 2:
The invention changes the geometric parameters of the guide slots by introducing slot constrictions at specific positions. These constrictions create predetermined threshold forces that must be overcome for the formations to pass through, providing reliable locking without requiring precise tolerances on the latch elements themselves. The slot constriction geometry becomes the critical parameter rather than the latch element dimensions.
2Reliability
If precise matching of mounting tolerances is required for latch elements, then sufficient locking force is obtained, but manufacturing complexity increases
Solution Approach 1:
The invention extracts the locking function from the latch elements and relocates it to the slot constrictions in the guide slots. The slot constrictions are formed directly in the mounting component's guide slots, eliminating the need for precise matching between separate latch elements and their receptacles. The threshold force mechanism is built into the slot geometry itself.
Solution Approach 2:
The slot constrictions automatically provide the locking function through their geometry. When the formations pass through the constrictions, the slot geometry itself generates the threshold force that creates reliable locking. No additional adjustment or precise matching is needed - the slot constriction design inherently provides the necessary locking force.
3Ease of manufacture
If a simple abutment structure is used for tilt locking, then manufacturing is simplified, but reliable locking against tilting may not be achieved
Solution Approach 1:
The invention adds a dimensional element to the tilt locking mechanism by using guide skids that extend substantially parallel to the insertion direction of the plug coupling. This parallel arrangement creates a second dimension of constraint that effectively prevents tilting while maintaining manufacturing simplicity. The guide skids work in conjunction with the slot constrictions to provide comprehensive tilt prevention.

AI summary
The mounting device serves to receive an electrical plug coupling for the connection of an electronic circuit assembly. It has a coupling receptacle (2), which is pivotally mounted on a door handle carrier (10) and is locked against tilting in an installation position and can be pivoted into an operational position. The coupling receptacle (2) is guided by means of two formations (9) projecting on opposite sides in parallel guide slots (7). The guide slots (7) each have at least one slot constriction (8″), through which the formations (9) can be forced only after overcoming a predetermined threshold force. Rigidly connected to the coupling receptacle (2) is at least one tilt locking element (13b). The tilt locking element comes into engagement, in the installation position, with an opposing component (16) fixed to the door and then comes out of engagement with the opposing component when the formations (9) have passed the slot constrictions (8″) in the guide slots (7).
