High-Voltage Plug Insulating Sleeve Recess Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for high-voltage medical equipment, such as X-ray generators, face challenges with electrical insulation due to the use of insulating liquids, which are difficult to apply perfectly, prone to leakage, and unsuitable for large-dimensional devices, especially when the equipment is in motion.
Innovation Solution
A connecting plug with a jacket and multiple recesses to hold insulating sleeves in place, preventing sliding and deformation, and using air-filled spaces between beadings for insulation, allowing for correct positioning and easy insertion, and accommodating thermal expansion without liquid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid insulator (oil or grease) is used to provide electrical insulation between the plug and receptacle, then electrical insulation is achieved, but the device becomes difficult to seal, prone to leakage, and requires vertical orientation during fitting
Solution Approach 1:
The patent extracts the liquid insulator from the system and replaces it with a solid insulating interface in the form of a sleeve made of flexible insulating material. This eliminates the sealing and leakage problems associated with liquid insulators while maintaining electrical insulation functionality.
Solution Approach 2:
The patent changes the physical state of the insulator from liquid to solid flexible material. This parameter change allows the insulator to maintain its insulating properties while eliminating the need for complex sealing and vertical orientation requirements.
2Ease of operation
If a sleeve of flexible material is used to replace the liquid insulator, then ease of operation is improved, but the sleeve tends to slide and deform during insertion in large-dimensional devices
Solution Approach 1:
The patent incorporates a recess in the jacket that is designed to receive and hold the insulating sleeve in its correct position before insertion. This preliminary positioning action prevents the sleeve from sliding or deforming during the insertion process, ensuring accurate positioning in large-dimensional devices.
3Reliability
If an insulating liquid is used, then electrical insulation is provided, but thermal expansion differences cause seal breaking and liquid leakage
Solution Approach 1:
The patent removes the liquid insulator from the system, eliminating the problem of thermal expansion differences between the liquid and surrounding components. The solid flexible sleeve does not suffer from the same thermal expansion issues that cause seal breaking and leakage in liquid-based systems.
4Reliability
If a liquid insulator is used in moving X-ray source equipment, then electrical insulation is achieved, but movement favors leakage in poorly sealed connections
Solution Approach 1:
The patent extracts the liquid insulator and replaces it with a solid flexible sleeve, eliminating the leakage problem that occurs during movement of the X-ray source. The solid material remains in place during rotation and movement, maintaining electrical insulation without requiring perfect sealing.
