Multi-Output Connector Bus Bar Layout for Noise-Protected Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors lack a design that efficiently manages multiple electrical connections while providing protection and noise reduction, particularly in electromechanical devices like automobiles and home appliances.
Innovation Solution
A connector design featuring a case with inputs and outputs, a terminal housing, terminals, and a bus bar, where at least one terminal is exposed through each output, allowing external connections, and includes a shield system for noise reduction and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple terminals are connected to a single input through a bus bar, then electrical connection efficiency is improved, but the connector structure becomes more complex
Solution Approach 1:
Multiple terminals are electrically connected to a single input through a common bus bar, merging multiple connection paths into a single integrated structure. This allows simultaneous electrical connections to multiple outputs from one input, improving connection efficiency while the bus bar's unified design actually reduces overall structural complexity compared to separate connection paths for each terminal.
2Ease of operation
If terminals are exposed through outputs for external connections, then ease of connection is improved, but protection and noise reduction become compromised
Solution Approach 1:
The terminal housing provides an enclosing structure that nests around the exposed terminals and bus bar components. This nested design allows terminals to remain accessible for external connections while being protected within the housing structure, simultaneously achieving ease of connection and protection/noise reduction without compromising either function.

AI summary
A connector includes a case having an input and a plurality of outputs, a terminal housing in the case, a plurality of terminals in the terminal housing, and a bus bar disposed inside the terminal housing and connected to the terminals. At least one terminal of the terminals is exposed to an outside through any one of the outputs and is connectable to an external terminal inserted into the case. Another terminal of the terminals is exposed to the outside through another output of the outputs and is connectable to another external terminal inserted into the case. At least some of the bus bar is in the input and exposed to the outside of the case.
