Solution Overview

Problem

The existing methods for attaching a current conductor to a current transformer housing require a long, energy-consuming, and time-consuming purely rotational movement of screws or set screws, which is inefficient, especially when dealing with multiple transformer housings.

Innovation Solution

A device that allows for the attachment of a current conductor using both translational and rotational movements of the holding and fastening elements, where the fastening element is guided through the holding element, enabling a quick and simple fastening process without the need for additional tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a purely rotational movement of screws or set screws is used to fasten the current conductor, then the current conductor can be securely fixed to the housing, but the assembly process becomes very energy-consuming and time-consuming

Engineering Contradiction:
Improvesecure fixation of current conductorVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fastening element is designed to perform both translational and rotational movements dynamically during the fastening process. The translational movement enables rapid approach of the fastening element to the conductor surface, while the rotational movement provides the final secure fixation. This dynamic combination resolves the contradiction by making the overall process faster while maintaining reliable fixation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention introduces a translational dimension to the traditional rotational fastening process. Instead of relying solely on rotational movement around the longitudinal axis, the fastening element can now move translationally along its longitudinal axis to rapidly cover distance and approach the conductor surface, adding a new dimension to the fastening operation that significantly reduces assembly time.

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

AI summary

The invention relates to a device for removably fixing a current conductor (1) to a current transformer housing (2), comprising the current transformer housing (2), a retaining element (3) which is led through the current transformer housing (2), a fixing element (4) which is led through the retaining element (3), and a clamping element (5), said fixing element (4) and/or retaining element (3) at least partly sitting against the surface of the current conductor (1) in a fixed state of the current conductor (1) to the current transformer housing (2). The fixing element (4) is rotatable about the fixing element longitudinal axis in a rotary manner in order to fix or remove the current conductor (1), and the clamping element (5) is arranged in a movable manner on the current transformer housing (2) such that the clamping element (5) allows a translational movement of the retaining element (3) along the retaining element longitudinal axis in order to fix or remove the current conductor (1) in a first position and prevents the translational movement of the retaining element (3) along the retaining element longitudinal axis in order to remove the current conductor (1) in a second position. As a result, the device according to the invention thus allows a particularly simple and quick fixing of a current conductor (1) to a current transformer housing (2).
