Universal Terminal Platform Block for Multi-Type Wire Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal platform blocks are unable to connect all types of lead wires simultaneously, requiring separate blocks for each wire and terminal shape, leading to inconvenience and complex stock management.
Innovation Solution
A terminal platform block design featuring a first and second terminal member with specific surface features and a fastening screw mechanism that allows for the connection of various lead wire types, including round, Y, rod, twist, and solid wires, by nipping the terminal portions between the members, enabling electrical connection of all lead wires with one block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional connection methods are used, then specific lead wire types can be connected, but only one type of lead wire can be connected per terminal platform block
Solution Approach 1:
The terminal platform block is designed with a universal structure that can accommodate multiple types of lead wires (round, Y-shaped, rod, twist, and solid wires) through a single block. The first and second terminal members create a clamping mechanism that adapts to different wire shapes and sizes, eliminating the need for multiple specialized blocks.
Solution Approach 2:
The terminal platform block is divided into distinct functional components: a first terminal member with a fitting hole, a second terminal member with a screw hole, and a fastening screw. This segmentation allows each component to perform its specific function while contributing to the overall versatility of the assembly.
2Reliability
If separate terminal platform blocks are prepared for each lead wire type, then proper connection is achieved, but stock management becomes complicated
Solution Approach 1:
By designing a single terminal platform block that can reliably connect all types of lead wires, the invention eliminates the need for complex stock management of multiple specialized blocks. The universal design maintains connection reliability while simplifying inventory control and distribution.
3Ease of operation
If a single terminal platform block connects all lead wire types, then stock management is simplified, but the structure must accommodate diverse terminal shapes
Solution Approach 1:
The terminal members are designed with specific surface features at different locations: the first terminal member has a fitting hole in its upper surface portion, while the second terminal member has a screw hole in its upper surface portion. This local differentiation allows the structure to accommodate diverse terminal shapes through the clamping action without requiring complex overall design.

AI summary
A terminal platform block (50) includes a movable terminal member (61, 71) and a fixed terminal member (67, 77), and nips a lead of wire by the movable terminal (61, 71) and the fixed terminal (67, 77) via a fastening screw (65). An upper surface portion (67a, 77a) of the fixed terminal member (67, 77) is fitted between an upper surface portion (61 a, 71 a) and a lower surface portion (61 c, 71 c) of the movable terminal member (61, 71), and the fastening screw (65, 75) fitted to a fitting hole (62, 72) of the movable terminal member (61, 71) is capable of being screwed into a screw hole (68, 78) of the fixed terminal member (67, 77).
