Busbar Adapter with Integrated Fuse and Plug-in Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for connecting electrical or electronic devices to busbar systems require significant assembly effort and are prone to errors due to the high number of electrical contacts and separate fuse connections, leading to inefficiencies in space usage and safety.
Innovation Solution
An adapter device with integrated fuses and plug-in contacts that allows for secure and quick electrical connection to a busbar system, featuring a compact design with self-resilient or spring-loaded contacts and a latching mechanism for easy installation and protection against accidental contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional separate fuse connections and multiple electrical contacts are used to connect electrical devices to busbar systems, then reliable electrical protection and connection are achieved, but assembly effort and installation time increase significantly
Solution Approach 1:
The patent combines multiple separate components (fuses, electrical contacts, and connection elements) into a single integrated adapter device. The adapter housing contains fuse holders with fuse elements, plug-in contacts for electrical connection, and integrated busbar contacting elements, all merged into one unit that can be installed as a single component rather than assembling multiple separate parts.
2Reliability
If multiple separate electrical contacts and fuse connections are made manually, then secure electrical connection is achieved, but the number of contacts required increases leading to higher complexity
Solution Approach 1:
The adapter device merges multiple electrical contact functions into a single integrated unit. The plug-in contacts are housed within the adapter housing along with the fuse elements and busbar contacting elements, reducing the number of separate contact components that need to be individually installed and connected.
Solution Approach 2:
The adapter device serves multiple functions simultaneously: it provides electrical connection via plug-in contacts, electrical protection through fuse elements, and busbar connection through integrated contacting elements. This multi-functional design eliminates the need for separate devices for each function, reducing overall system complexity.
3Reliability
If fuses are connected to electrical devices via separate lines, then individual protection for each current phase is achieved, but space requirements and wiring complexity increase
Solution Approach 1:
The adapter device combines the fuse holders containing individual fuse elements for each current phase directly within the adapter housing. This integration eliminates the need for separate wiring routes for each fuse connection, as all fuse elements are housed in a compact unit that connects to the busbar system through integrated contacting elements.
Solution Approach 2:
The fuse elements are nested within the adapter housing, which itself is connected to the busbar system. This nested arrangement allows individual protection for each current phase while maintaining a compact footprint, as the fuse holders are contained within the overall adapter structure rather than requiring separate external mounting space.
