Branch Connector Maintaining Twisted Pair Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional branch connectors for twisted pair cables deteriorate communication quality by unwinding the twisted shape of cables, leading to ineffective branching in communication networks.
Innovation Solution
A branch connector design that maintains the twisted shape of cables by using a first housing with twist grooves and ribs to increase the distance between cables, while a second housing with pressure contact terminals ensures secure connection and assembly, ensuring the twisted shape is preserved during branching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the twisted shape of cables is unwound in the branch connector, then the cables can be easily connected and assembled, but the communication quality deteriorates
Solution Approach 1:
The branch connector is divided into a first housing for receiving twisted cables and a second housing for connection terminals, allowing the twisted structure to be preserved in one section while enabling connection in another
Solution Approach 2:
A cable receiving portion with twist grooves acts as an intermediary structure that maintains the twisted configuration of cables while facilitating their connection to terminals through the housing assembly
2Reliability
If the distance between two first cables is increased, then the twisted shape can be maintained, but the space required in the connector increases
Solution Approach 1:
The connector utilizes three-dimensional spatial arrangement with twist grooves that follow the twisted path of cables, allowing increased cable separation distance within a compact overall volume by exploiting vertical and lateral dimensions
3Reliability
If pressure contact terminals are used to connect cables, then the connection reliability is improved, but the risk of damaging the cable insulating sheath increases
Solution Approach 1:
The insulating sheath serves as an intermediary protective layer that guides the pressure contact blades to the conductor while preventing direct damage, allowing reliable electrical connection without compromising cable integrity
Solution Approach 2:
The pressure contact blades are designed with controlled dimensions and elasticity parameters that enable them to penetrate the insulating sheath to the conductor without excessive force that would cause damage

AI summary
A branch connector includes: a first housing having a wiring route portion in which two first cables constituting a twisted pair cable are wired in a twisted shape to be spaced apart from each other; and a second housing to which a pair of pressure contact terminals connected respectively with two second cables constituting a twisted pair cable is fixed. The pair of pressure contact terminals is connected respectively with the two first cables by pressure contact in a state where the second housing is assembled with the first housing.
