Distribution Terminal With Offset Cable Bores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distribution terminals have limitations in terms of overall width, making them difficult to handle and install in compact spaces, and they often require specialized screws or materials to maintain structural integrity and meet safety standards.
Innovation Solution
The distribution terminal design features vertically offset cable insertion openings and bores in the clamping body, allowing for a compact arrangement with a reduced overall width, and includes a detachable upper housing part for enhanced safety and ease of handling, along with a baying profile for improved space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If cable insertion openings and bores are arranged at the same height level, then the structural simplicity is maintained, but the overall width of the distribution terminal increases
Solution Approach 1:
The patent applies vertical offset arrangement of cable insertion openings and bores, transitioning from a horizontal alignment (same height level) to a vertical dimension arrangement. This dimensional change allows the openings to be positioned at different height levels, enabling a compact layout that reduces the overall width of the distribution terminal while maintaining structural integrity
2Area of stationary object
If the distribution terminal is designed with compact dimensions for space efficiency, then space utilization improves, but the handling and installation difficulty increases
Solution Approach 1:
The distribution terminal is segmented into modular components including the housing, clamping body, and vertically arranged cable insertion openings. This segmentation allows each component to be optimized independently - the compact vertical arrangement reduces installation space while standardized modular components maintain ease of handling and installation
3Length of stationary object
If vertically offset cable insertion openings are implemented, then the overall width is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent implements local quality by providing different cross-sectional dimensions for different bores (first bore with first cross section, second bore with second cross section). This allows each bore to be precisely manufactured for its specific function while the vertical offset arrangement overall reduces the terminal width. The varying cross sections enable optimized positioning that accommodates manufacturing tolerances

AI summary
The invention relates to a distribution terminal, in particular a main conductor connecting terminal (10), comprising at least one terminal body (18) that is disposed in a housing (12) and has two front faces (20, 22; 56, 48) and two side faces (24, 26; 60, 62), and further comprising at least one pair of conductor insertion openings (28) disposed at offset heights in the front faces (20, 22) and two bores (52) that adjoin the conductor insertion openings (28) and are disposed at offset heights in the or each terminal body (18), characterised in that each bore (52) in the terminal body (18) is formed on the front faces (56, 58) of said body in a bore surface portion (64, 66), and the bore surface portions (64, 66) of both bores (52) overlap in some parts.
