Solution Overview
Problem
Conventional connections between coaxial cables and printed circuit boards require additional elements like connectors and are limited to the edge of the board, making them costly and inflexible.
Innovation Solution
A solder connection method that allows coaxial cables to be connected to any part of the printed circuit board using a slanted arrangement with outer and inner conductor contact areas, eliminating the need for connectors and enabling flexible placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are used to connect coaxial cable to printed circuit board, then connection reliability is improved, but device complexity and cost increase
Solution Approach 1:
The invention extracts and eliminates the connector component from the connection system. By directly soldering the coaxial cable conductors to the printed circuit board contact areas, the patent removes the intermediate connector element, thereby reducing device complexity and cost while maintaining connection reliability through proper solder joint design
Solution Approach 2:
The invention merges the functions of the connector and the printed circuit board mounting structure into a single integrated solution. The outer conductor receiving opening and contact areas are directly formed on the printed circuit board, combining what were previously separate connector and board mounting functions into one unified structure
2Ease of manufacture
If coaxial cable is connected only at the edge of printed circuit board, then manufacturing simplicity is maintained, but adaptability and flexibility are reduced
Solution Approach 1:
The invention creates a universal connection structure that can be implemented at any location on the printed circuit board. The outer conductor receiving opening and associated contact areas can be fabricated anywhere on the board surface, allowing the same connection method to serve multiple positions and applications, thereby achieving both manufacturing simplicity and placement flexibility
Solution Approach 2:
The invention transitions from edge-only connection (one-dimensional constraint) to surface-wide connection capability (two-dimensional freedom). By forming contact areas and receiving openings on the board surface rather than limiting connections to the edge, the patent enables flexible placement while maintaining straightforward manufacturing processes
3Reliability
If additional connectors are used for cable connection, then connection stability is improved, but cost increases
Solution Approach 1:
The invention extracts the connector component from the assembly, eliminating it entirely. The coaxial cable is connected directly to the printed circuit board through solder joints at contact areas, removing the need for additional connector hardware and reducing overall component quantity and cost

AI summary
A solder connection between a coaxial cable and a printed circuit board arrangement. The coaxial cable comprises an inner conductor, an outer conductor and a dielectric arranged in between. The printed circuit board arrangement comprises an outer conductor contact area and an inner conductor contact area. The outer conductor contact area comprises an outer conductor receiving opening. The coaxial cable runs at an angle to the printed circuit board arrangement, wherein a part of the outer conductor is arranged in the outer conductor receiving opening and wherein the inner conductor is arranged at the inner conductor contact area. A first solder joint connects the outer conductor to the outer conductor contact area. A second solder joint connects the inner conductor to the inner conductor contact area.
