Terminal Block Actuating Rocker for One-Handed Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection blocks for electrical lines, particularly for ceiling and wall lights, complicate assembly and disassembly when only two hands are available, as they require holding the cable, tool, and terminal simultaneously.
Innovation Solution
A connection block with actuating rocker switches that allow easy opening of terminal contacts for removal, coupled with a plug-in receptacle and a housing design featuring a film hinge and sliding guide for secure and tool-free assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional terminal blocks are used for overhead installation, then electrical connections can be made, but assembly and disassembly become difficult when only two hands are available
Solution Approach 1:
The terminal contacts are designed to be movable between closed and open positions through the actuating rocker. This dynamic feature allows the terminal contacts to transition from a fixed closed state (providing secure electrical connection) to an open state (allowing easy cable removal), resolving the contradiction between secure connection and ease of disassembly
Solution Approach 2:
The actuating rocker is designed to be operable by finger pressure alone, without requiring additional tools or hands. The mechanical advantage provided by the rocker lever allows a single hand to simultaneously hold the cable and actuate the terminal contact opening, enabling self-service operation with limited hands
2Reliability
If terminal contacts are made secure and permanent, then reliable electrical connection is achieved, but disassembly for repair or replacement becomes difficult
Solution Approach 1:
The terminal contacts incorporate a movable design that transitions between securely closed positions (ensuring reliable electrical connection) and open positions (enabling easy disassembly). The spring element provides continuous contact pressure for reliability while the rocker mechanism enables controlled opening for repair access
Solution Approach 2:
The actuating rocker is pre-positioned and accessible from the front of the device, allowing the user to prepare for disassembly by simply pressing the rocker before attempting to remove cables. This preliminary action opens the terminal contacts in advance, making the subsequent disassembly process straightforward
3Adaptability or versatility
If multiple components are used for terminal contacts and rockers, then functionality is achieved, but assembly time increases
Solution Approach 1:
The rocker element is integrated directly with the terminal contact assembly, forming a unified movable component. The spring element is incorporated into the same assembly, creating a compact unit that combines multiple functions (actuation, contact pressure, and terminal opening) into a single integrated component, thereby reducing assembly steps and time

AI summary
A terminal block for electrical conductors comprises a housing in which at least two clamping contacts, each for at least one conductor, are arranged, with each clamping contact being capable of being moved into an open position by an actuating rocker. A coupling device is provided on the housing.
