Wiring Wrench Latching Mechanism for Terminal Block Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal block wiring operations are inconvenient and prone to damage due to the use of screwdrivers, which are not designed for wiring, leading to potential tool misuse and equipment damage.
Innovation Solution
A terminal block assembly and wiring wrench system featuring a press rod with a pressing protruding arm and a handle with a clamping protruding arm, coupled by a pivoting structure, where an elastic arm drives the arms to move closer, securely latching the wrench to the terminal block, allowing for convenient and secure wiring without damaging tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screwdriver is used for wiring operation, then the wiring can be completed, but the operation is inconvenient and the terminal block may be damaged easily
Solution Approach 1:
A dedicated wiring wrench is introduced as an intermediary tool between the operator and the terminal block. The wrench features a pressing protruding arm that engages with the pressing portion of the terminal block, and a clamping protruding arm that secures the terminal block body, allowing safe and convenient wiring operations without damaging the terminal block
Solution Approach 2:
The wiring wrench is divided into functional segments: a handle for gripping, a pivoting structure for motion transmission, an elastic arm for providing pressing force, a pressing protruding arm for engaging the pressing portion, and a clamping protruding arm for securing the terminal block body. Each segment performs a specific function to resolve the contradiction
2Ease of operation
If a dedicated wiring wrench is designed, then the wiring operation becomes convenient and secure, but the device complexity increases
Solution Approach 1:
The wiring wrench combines multiple functions into a single integrated tool: the handle and pressing protruding arm form a pressing mechanism, while the clamping protruding arm forms a clamping mechanism. The pivoting structure and elastic arm merge the motion transmission and force application functions, creating a compact yet functional design that balances complexity with operational convenience
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables secure latching and convenient operation of the terminal block assembly, preventing damage and simplifying the wiring process by using a dedicated wrench that securely engages with the terminal block, allowing cables to be inserted and connected without requiring additional tools.
Implementation Method 1
an elastic arm extended from the other side of the handle, and the clamping protruding arm and the pressing protruding arm being configured to be opposite to each other, and the elastic arm selectively abutting the stop portion

AI summary
Disclosed are a terminal block assembly (10) and its wiring wrench (2). The wiring wrench (2) includes a press rod (21) and a handle (22), and the press rod (21) has a pressing protruding arm (211) on a side and a stop portion (212) on the other side, and the handle (22) and the press rod (21) are connected by a pivoting structure (23), and the handle (22) has a clamping protruding arm (221) on a side and an elastic arm (222) on the other side, and the clamping protruding arm (221) and the pressing protruding arm (211) are configured to be opposite to each other, and the elastic arm (222) may selectively abut at the stop portion (212). Therefore, the wiring wrench (2) can be latched securely with the terminal block (1) to provide the effect of latching the terminal block (1) conveniently.
