Cable Clamp for Coaxial Cable PCB Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for coupling coaxial cables to printed circuit boards, such as using U.FL connectors or soldering, introduce signal path discontinuities and induce series inductance and shunt capacitance, compromising high-frequency performance, especially for signals above 3 GHz.
Innovation Solution
A cable clamp system that crimps around the coaxial cable and includes a projection for insertion into a printed circuit board opening, allowing fixed coupling via soldering, thereby minimizing dielectric extension and preventing outer conductor fraying, while maintaining impedance integrity.

1Ease of operation
If a U.FL connector is used to couple the cable to the printed circuit board, then the cable can be easily connected, but signal path discontinuities are introduced that compromise high-frequency performance
Solution Approach 1:
The patent removes the traditional connector component entirely, extracting the problematic element that caused signal discontinuities. Instead of using a U.FL connector, the cable is soldered directly to the PCB, eliminating the connector's mechanical interface and associated signal path discontinuities while maintaining ease of connection through direct soldering.
Solution Approach 2:
The patent merges the cable assembly with the PCB by soldering the cable conductors directly to the PCB traces, combining what were previously separate components (connector, cable, PCB) into a more integrated assembly. This merging eliminates the intermediate connector interface that caused signal integrity issues.

AI summary
Apparatus, methods, and systems for coupling a cable to a printed circuit board are described herein. In some embodiments, a portion of a cable clamp is configured to be crimped about a cable having an inner conductor and an outer conductor, such as a coaxial cable. The cable clamp can have a projection configured to be inserted into an opening of a printed circuit board. The cable clamp can be configured to be fixedly coupled, for example, soldered, to the printed circuit board.
