Terminal Block Layout for Compact Size and Clear Release Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal blocks face challenges in achieving a compact size both in height and width due to the arrangement of insertion-receiving portions and release operating elements, leading to operational inefficiencies and increased dimensions.
Innovation Solution
The terminal block is designed with first and second insertion-receiving portions arranged in orthogonal directions and release operating elements positioned differently in the width direction, allowing for a compact, thin, and operable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all insertion-receiving portions are arranged in a row along the height direction, then each portion can be accessed easily, but the terminal block becomes large in the height direction
Solution Approach 1:
The patent transitions from a single-row arrangement to a multi-row arrangement where insertion-receiving portions are distributed across multiple rows in the width direction. This dimensional redistribution reduces the height requirement while maintaining accessibility through strategic positioning of release operating elements.
2Length of stationary object
If insertion-receiving portions are arranged in two rows to reduce height, then the height direction size is reduced, but the terminal block becomes large in the width direction
Solution Approach 1:
The patent merges the functions of multiple release operating elements into a single integrated structure that serves multiple insertion-receiving portions across different rows. This consolidation reduces the overall width requirement by eliminating redundant individual operating elements while maintaining the ability to release connections in all rows.
3Device complexity
If release operating elements are positioned directly above or below insertion-receiving portions, then the structure is simple, but operators may experience obstructions when operating
Solution Approach 1:
The patent employs asymmetric positioning where release operating elements are offset from direct alignment with their corresponding insertion-receiving portions. This asymmetric arrangement eliminates operational obstructions by ensuring that operators can access release elements without interference from cables or components associated with the insertion-receiving portions, while maintaining structural efficiency.

AI summary
A terminal block includes a plurality of inserted portions and a plurality of release operators, wherein: the inserted portions include first inserted portions and second inserted portions which are arranged in a row in a first direction, and which have mutually different positions in relation to the first direction and a second direction perpendicular to the first direction; and the plurality of release operators are arranged in the first direction, in different positions to the first inserted portions and the second inserted portions in relation to the second direction.
