Clamping Spring Actuation for Flexible Conductor Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for electrical conductors, particularly those with flexible conductors, require cumbersome manual actuation to pivot the clamping spring away from the current bar for insertion and subsequent clamping, increasing assembly time and difficulty.
Innovation Solution
A connection arrangement featuring a housing, conductor connection space, clamping spring with a pivotable clamping leg, and an actuating element that can be latched to hold the open position, allowing for easy insertion and secure clamping of flexible conductors without manual actuation, utilizing a release element to convert the clamping leg from the open to the clamping position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual actuation is required to pivot the clamping spring away from the current bar, then flexible conductors can be inserted, but the assembly process becomes cumbersome and time-consuming
Solution Approach 1:
The actuating element is pre-positioned in a latched state that automatically holds the clamping spring in the open position, eliminating the need for manual actuation during assembly. The latching mechanism performs the opening action in advance, allowing flexible conductors to be inserted without cumbersome manual operation.
2Ease of operation
If the clamping spring is held in open position without locking, then insertion is easier, but the clamping leg cannot maintain the open position automatically
Solution Approach 1:
The latching mechanism between the actuating element and housing automatically maintains the open position of the clamping spring without requiring continuous manual intervention. The system serves itself by using the latched actuating element to hold the clamping spring open, ensuring both ease of insertion and reliable position maintenance.
3Adaptability or versatility
If dual actuation is required for insertion and clamping, then flexible conductors can be connected, but the number of操作步骤 increases
Solution Approach 1:
The latching function is extracted from the manual actuation process and integrated into the actuating element itself. By removing the need for separate manual steps to maintain the open position, the system reduces the number of operation steps while maintaining the ability to connect flexible conductors, thereby improving assembly speed.
