Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection structures of coaxial cables to circuit boards face instability and insufficient connection area due to size differences between internal and external conductors, leading to unreliable connections, especially on flat circuit boards where space-saving designs are required.
Innovation Solution
A terminal structure for coaxial cables that includes an internal conductor connection portion, a removal portion, and an external conductor connection portion, where the internal conductor is connected via a conducting portion on the end face, and the external conductor is connected separately, with the removal portion ensuring a stable and space-saving connection on a flat circuit board by exposing and coating the conductors with a copper plating layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the length of the terminal is shortened to save space on the circuit board, then the connection portion becomes more compact, but the connection area becomes insufficient
Solution Approach 1:
The invention transitions from a linear arrangement to a planar arrangement by forming connection portions on the end face of the coaxial cable. The internal conductor connection portion and external conductor connection portion are arranged side-by-side on the same plane rather than one after another along the length, effectively utilizing two-dimensional space to maintain sufficient connection area while reducing the required cable length.
2Reliability
If the internal conductor and external conductor are connected separately to terminals on a flat circuit board, then the connection structure becomes more complex, but the connection stability improves
Solution Approach 1:
The invention divides the connection structure into two separate connection portions: an internal conductor connection portion for connecting the internal conductor to a terminal, and an external conductor connection portion for connecting the external conductor to another terminal. This segmentation allows each conductor to be connected independently to terminals on the flat circuit board, improving connection stability despite the increased structural complexity.
3Shape
If the internal conductor and external conductor have different outer diameters, then the coaxial cable structure is maintained, but the connection to flat circuit board terminals becomes unstable
Solution Approach 1:
The invention resolves the diameter mismatch issue by arranging both connection portions on the same plane at the end face of the coaxial cable. This planar arrangement allows conductors of different diameters to connect to terminals on a flat circuit board simultaneously without compromising stability, as the connection stability is determined by the planar configuration rather than the axial alignment of different diameter conductors.

AI summary
A terminal structure include an internal conductor connection portion, a removal portion and an external conductor connection portion. The internal conductor connection portion is connected to a internal conductor via a conducting portion and an external conductor. The removal portion is provided at a rear side relative to the internal conductor connection portion. The external conductor connection portion is provided at a rear side relative to the removal portion, is formed in the outer peripheral surface of the external conductor, is shut off from the internal conductor connection portion by the removal portion, and is connected to the external conductor.
