Clamping Spring Connection for Direct Plug-In Flexible Conductors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for electrical conductors, particularly flexible ones, require manual actuation of a clamping spring to transition between clamping and release positions, complicating the mounting process and increasing handling time.
Innovation Solution
A connection arrangement with a clamping spring, actuator, guide element, and release element that allows flexible conductors to be directly plugged in, where the release element is actuated by the conductor's insertion, enabling the guide element to displace and transfer the clamping leg into the clamping position without additional manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual actuation of the actuating means is required to transfer the clamping spring into the release position for inserting flexible conductors, then the conductor can be inserted into the connection space, but the handling becomes inconvenient and the time required increases
Solution Approach 1:
The conductor itself acts as the actuating means during insertion. When the conductor is inserted into the connection space, it automatically transfers the clamping spring from the clamping position to the release position through the mechanical interaction with the guide element and release element, eliminating the need for separate manual actuation by the user
Solution Approach 2:
The guide element and release element are pre-configured in the housing to detect the insertion of the conductor and automatically trigger the position change of the clamping spring before the conductor reaches its final clamped position, preparing the connection space in advance
2Ease of operation
If the clamping spring is held in the release position by the guide element during conductor insertion, then the conductor can be inserted without resistance, but additional components increase device complexity
Solution Approach 1:
The guide element serves multiple functions: it guides the conductor during insertion, holds the clamping spring in the release position, and interacts with the release element to enable automatic position transfer. This multi-functionality reduces the need for separate dedicated components for each function
Solution Approach 2:
The guide element and release element are integrated into the housing structure, combining the functions of positioning, guiding, and actuating into a unified component system rather than separate independent mechanisms

Function Achieved in This Case
Facilitates simple and time-efficient connection of flexible conductors by eliminating the need for manual actuation during the transition of the clamping spring, enhancing handling convenience.
Implementation Method 1
a clamping spring (111) comprising a clamping leg (113) which can be transferred into a clamping position and into a release position
Implementation Method 2
the guide element (115) is displaceable by a spring force of the clamping leg (113) such that the clamping leg (113) is transferrable into the clamping position

AI summary
A connection arrangement for connecting an electrical conductor includes: a housing; a busbar; a clamping spring including a clamping leg transferrable into a clamping position and into a release position; an actuator by which a compressive force is applicable to the clamping leg for transferring the clamping leg from the clamping position into the release position; a conductor connection space formed between a section of the busbar and of the clamping leg of the clamping spring; a displaceably arranged guide element in operative connection with the clamping leg of the clamping spring, the clamping leg being holdable in the release position by the guide element; and a release element, which in the release position of the clamping leg of the clamping spring is in engagement with the guide element. The release element, during insertion of the conductor to be connected into the conductor connection space, actuates by the insertion.
