Connector With Selective Noise Reduction For Branch Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional joint connectors with noise reduction members for all terminals lead to increased size and cost, and complicate the connection process for branch lines branching off a trunk line, as they require unnecessary division and terminal placement along the trunk line, potentially degrading communication performance.
Innovation Solution
A connector design where noise reduction members are only provided for branch-line connection terminals prone to noise, with trunk-line connection terminals lacking these members, allowing direct pressure contact and reducing the number of components, thereby minimizing size and cost increases and simplifying connection work.

Engineering Contradiction Analysis
1Object-affected harmful factors
If noise reduction members are provided for all terminals, then noise suppression is improved, but connector size and cost increase
Solution Approach 1:
The patent applies local quality by providing noise reduction members only at specific terminals (branch-line connection terminals) rather than uniformly at all terminals. This is based on the recognition that noise primarily occurs at branch-line terminals due to higher terminal resistance, while trunk-line terminals have lower resistance and generate less noise. The selective placement reduces connector size and cost while maintaining effective noise suppression where it is most needed.
2Object-affected harmful factors
If noise reduction members are provided for all terminals, then noise suppression is improved, but manufacturing cost increases
Solution Approach 1:
The patent reduces manufacturing cost by applying noise reduction members only where necessary - specifically at branch-line connection terminals that are prone to noise due to higher terminal resistance. This selective application reduces material costs and assembly complexity compared to providing noise reduction members at all terminals, while still achieving effective noise suppression.
3Adaptability or versatility
If trunk line is divided and terminals are attached for mating connector connection, then connection functionality is improved, but connection work complexity increases
Solution Approach 1:
The patent applies segmentation by separating terminals into two functional groups: trunk-line connection terminals for direct trunk line connection and branch-line connection terminals for mating connector connection. This functional segmentation allows the connector to maintain connection versatility while simplifying installation - the trunk line can be directly connected to trunk-line terminals without division, while branch lines are connected through the mating connector interface.
Solution Approach 2:
The patent extracts the mating connector connection function to dedicated branch-line connection terminals, separating it from the trunk line connection function. This extraction allows the trunk line to be directly connected without division or additional terminal attachment work, while the mating connector connects to the extracted branch-line terminals, simplifying the overall connection process.

AI summary
A connector is equipped with a housing capable of being fitted in a mating connector, a plurality of terminals which are held in the housing and electrically connected to each other, and a noise reduction member or members which are held in the housing. The mating connector is connected to brunch lines among a trunk line and the brunch lines constituting an electric circuit. One of the plurality of terminals is a trunk-line connection terminal which is a pressure contact terminal and is electrically connected to the trunk line directly, and a remaining terminals are branch-line connection terminals which are male terminals or female terminals and are electrically connected to the respective branch lines when the housing is connected to the mating connector. The noise reduction member is not disposed at the trunk-line connection terminal, and the noise reduction member is disposed at the branch-line connection terminal.
