Solution Overview

Problem

Existing connection devices face challenges in accommodating increasingly cramped space conditions and miniaturization of electrical components, as they require more compact designs while maintaining effective actuation mechanisms for releasing electrical conductors.

Innovation Solution

A connection device with a direct-plug-in clamping connection featuring a clamping spring and actuation mechanism that can be moved from a base position to an actuation position, with actuation regions arranged at an angle greater than 0°, allowing for a more compact configuration and controlled actuation, and incorporating a guide and mating guide for smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the actuation mechanism is designed with a fixed rotational axis, then the structure is simple, but the device size is larger and cannot accommodate cramped space conditions

Engineering Contradiction:
Improvedevice sizeVSAvoidactuation mechanism structure
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the actuation mechanism from a fixed rotational axis system to a moving rotational point system. The guide element constrains the actuation mechanism to follow a specific path, causing the rotational point to move dynamically during actuation. This dynamic approach enables a more compact device configuration while maintaining the necessary actuation functionality for releasing electrical conductors in cramped spaces.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide element serves as an intermediary component between the actuation mechanism and the housing. It mediates the motion of the actuation mechanism by constraining it to a specific path, thereby enabling the moving rotational point behavior without requiring complex internal mechanisms. The guide translates the actuation force into the desired motion pattern, resolving the contradiction between compact size and functional complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the actuation regions are arranged at a larger angle range, then accessibility for actuation tools is improved, but the device configuration becomes more complex

Engineering Contradiction:
Improveaccessibility for actuation toolsVSAvoidactuation mechanism configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent resolves this contradiction by arranging actuation regions at angles greater than 0° relative to each other, utilizing angular dimensionality to improve tool accessibility. The moving rotational point mechanism allows the actuation force to be applied from multiple angular directions while maintaining a compact configuration. This dimensional approach enables operators to access the actuation mechanism from different angles without increasing overall device complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Volume of moving object

If the connection device is made more compact, then it satisfies cramped space conditions, but the actuation mechanism becomes harder to operate

Engineering Contradiction:
Improveconnection device sizeVSAvoidactuation operation
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent applies segmentation by dividing the actuation mechanism into distinct functional elements: the actuation mechanism itself, the guide element, and the clamping spring. This segmentation allows each component to be optimized for its specific function while working together in a compact arrangement. The guide element segments the motion path, enabling the actuation mechanism to move through a controlled trajectory that maintains operational ease despite the compact overall device size.

Inventive Principle:
Principle #1Segmentation

AI summary

A connection device comprises at least one direct-plug-in clamping connection which has a direct-plug-in design for plugging in an electric conductor and which has a clamping spring, busbar and/or a clamping cage. The clamping spring is designed to clamp an electric conductor plugged into the direct-plug-in clamping connection to contact the busbar and/or the clamping cage in an electrically conductive manner. The direct-plug-in clamping connection additionally has an actuation mechanism which can be moved from a base position to an actuation position and back. In the actuation position, the actuation mechanism moves the clamping spring so as to release the electric conductor, wherein the actuation mechanism has at least two actuation regions which are provided for an actuation tool and which are arranged at an angle greater than 0 ° relative to each other. When the actuation mechanism is moved from the base position to the actuation position and returned back to the base position from the actuation position, it is moved about an imaginary rotational point which changes the position. A series connection assembly comprises at least two such connection devices designed in the form of series connection devices. A method is provided for installing such a connection device.
