Lockable Connection Module for Busbar Current Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection modules for distributing direct current along a support rail are unsuitable for high currents due to increased installation height and numerous contact points, making them inefficient for systems like 40 A direct current distribution.
Innovation Solution
A connection module with a housing featuring a crossbar and latching profile for positive-locking attachment to busbar modules, allowing reliable and releasable mounting, and incorporating a pivot lever and spring-elastic element for secure contact and easy removal, enabling efficient distribution of direct current without increasing structural height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection sliders are used to electrically connect adjacent connection modules, then electrical connection is achieved, but installation height increases and the system becomes unsuitable for high direct currents
Solution Approach 1:
The patent transitions from vertical connection sliders to horizontal busbar modules that extend continuously along several connection modules. This dimensional change allows current distribution without increasing installation height, as the busbars run longitudinally through the housing rather than requiring vertical clearance for sliders.
2Productivity
If busbars extending continuously along several connection modules are used, then wiring expenditure is reduced and high direct current distribution is enabled, but the mechanical connection must be both reliable and releasable
Solution Approach 1:
The patent implements a dynamic mounting system where the connection module can be easily inserted and locked into position on the busbar module. The housing features a rear side that mounts to the busbar module, allowing for simple attachment and detachment operations while maintaining secure electrical connection during operation.
3Reliability
If the connection module is designed for secure mechanical connection to busbar modules, then electrical contact reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the mechanical mounting function and electrical connection function into an integrated busbar module system. The busbar module serves both as the mechanical support structure and as the electrical conductor, eliminating the need for separate connection mechanisms and reducing overall device complexity while maintaining reliable electrical contact.

AI summary
A connection module for mounting on a busbar module or several busbar modules extending in a longitudinal direction includes: a housing, a rear side of which is mounted or mountable on the busbar module or busbar modules; a crossbar, movable on a first longitudinal side of the rear side of the housing transversely to the longitudinal direction, so as to provide a positive-locking connection of the connection module to the busbar module or the busbar modules in a mounted position of the connection module; and a latching profile on a second longitudinal side, opposite the first longitudinal side, of the rear side of the housing, the latching profile providing a positive-locking connection of the connection module to the busbar module or the busbar modules in the mounted position.
