Plug-in Connection Fixing Element for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plug-in connections experience premature wear due to vibration-induced movement between electrical conductors and contact elements, leading to increased contact resistance and potential failure, as existing fixation methods only stabilize the insulation, allowing conductor movement to transfer to the contact.
Innovation Solution
A plug-in connection design where the electrical conductor is directly mechanically connected to a contact carrier via a fixing element, eliminating relative movement between the conductor and contact element by absorbing and dissipating conductor movements through the carrier, thereby preventing wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the line is fixed only on the cable insulation, then the insulation is stabilized, but the electrical conductor can still move relative to the contact element causing wear
Solution Approach 1:
The patent segments the fixation function by introducing a separate fixing element that specifically targets the electrical conductor, distinct from the cable insulation fixation. This allows independent stabilization of the conductor while maintaining insulation stability.
Solution Approach 2:
The fixing element acts as an intermediary component between the electrical conductor and the contact carrier. It provides a dedicated mechanical connection that prevents conductor movement without interfering with the insulation fixation or electrical contact function.
2Device complexity
If the conductor is allowed to move freely, then the assembly is simpler, but vibration causes relative movement between pin and contact leading to premature failure
Solution Approach 1:
The fixing element serves as a simple intermediary component that provides effective conductor fixation without complex mechanisms. It captures the conductor and attaches it to the contact carrier in a straightforward manner.
Solution Approach 2:
The fixing element is designed to be self-contained, providing both the capture and fixation functions in a single component that integrates with the existing contact carrier structure, eliminating the need for additional complex fixation systems.

AI summary
A plug-in connection is described having a contact carrier including a contact element, which is mechanically connected to the contact carrier; a line has an electrical conductor, which is electrically connected to the contact element, and has an insulation which surrounds the electrical conductor. The line is mechanically connected to the contact carrier, the plug-in connection having a fixing element, into which is accommodated an uninsulated area of the line in which the electrical conductor is not surrounded by the insulation, and which fixes the electrical conductor to the contact carrier.
