Solution Overview
Problem
Conventional high-voltage coaxial cables and connectors face difficulties in flexible assembly and separation, insulation performance deterioration due to bending, and spatial limitations, making it hard to replace individual components when dielectric breakdown occurs.
Innovation Solution
A high-voltage coaxial cable and connector design featuring a threaded coupling mechanism between the cable core and connector inside electrode, along with a corrugated coupling portion and extended dielectric structure, ensuring stable electrical contact and insulation resistance, allowing for repeated assembly and separation without compromising performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating glue is applied onto the coupled portion to ensure insulation performance, then insulation performance is improved, but the ease of assembly and separation deteriorates
Solution Approach 1:
The patent removes the insulating glue from the coupled portion between the connector and cable core, extracting the harmful adhesive substance that prevented easy assembly and separation. Instead, it uses a threaded coupling mechanism that provides both mechanical connection and insulation without requiring glue.
Solution Approach 2:
The patent segments the insulation function from the coupling function by using a threaded connector body that provides both mechanical fastening and electrical insulation separately, rather than relying on glue to provide both functions simultaneously.
2Reliability
If the coaxial cable is designed with fixed coupling to ensure stable electrical contact, then electrical contact stability is improved, but the adaptability for repeated assembly and separation deteriorates
Solution Approach 1:
The patent transitions from a fixed, permanent coupling design to a dynamic, reusable threaded coupling mechanism. The threaded connection allows the connector to be repeatedly assembled and separated while maintaining stable electrical contact through precise thread engagement between the connector body and cable core.
3Reliability
If the connector and cable are designed as integrated units to ensure insulation performance, then insulation performance is improved, but the ease of repair deteriorates
Solution Approach 1:
The patent segments the connector and cable core into separable components with threaded coupling, allowing individual replacement of either the connector or cable core while maintaining insulation performance through the threaded connection design that provides both mechanical fastening and electrical insulation.
Solution Approach 2:
The threaded coupling mechanism allows damaged components (connector or cable core) to be easily discarded and replaced individually, while the intact threaded portion can be recovered and reused, facilitating maintenance and repair without replacing the entire assembly.
4Ease of operation
If the coaxial cable is bent to achieve flexible wiring, then flexibility is improved, but the insulation performance deteriorates
Solution Approach 1:
The patent addresses the insulation issue in bent cables by extending the dielectric structure in the radial dimension (outward) to cover the coupled portion, rather than relying solely on longitudinal dielectric extension. This radial dielectric barrier maintains insulation performance even when the cable is bent, as it provides coverage in the direction where breakdown would occur during bending.

AI summary
A high-voltage coaxial cable and a connector are provided. The connector includes inner connector electrode, a connector dielectric enclosing an inner connector electrode, and an external connector housing. The inside electrode of a connector is provided with a tapped hole in one side thereof. The tapped hole corresponds to the threaded single core of a high-voltage coaxial cable. The inside electrode of a connector is selectively assembled with and separated from the high-voltage coaxial cable by selectively screwing the threaded single core into and away from the tapped hole. The connector dielectric is formed along the circumferential surface of the inside electrode, and is provided with a coupling portion. The coupling portion couples the connector with another connector, and is formed to a preset depth in a corrugated shape. The connector housing is formed in a shape that surrounds the connector dielectric.
