Electric probe for shock wave measurement and making method thereof

Abstract

The invention discloses an electric probe for shock wave measurement and a making method thereof. The electric probe is mainly composed of a metal capillary tube, an enameled wire, a metal lead and aheat shrinkable tube, wherein one end of the enameled wire is coated with an insulating coating and is arranged in the metal capillary tube in a passing mode, the top part is coated with a conductiveadhesive for being cured and fixed and the tail part is bonded and fixed by using a resin adhesive; the other end of the enameled wire is subjected to painting scraping and tin immersion; the metal lead is wound on the tail part of the metal capillary tube and is sleeved with heat shrinkable tube for being fixed; the metal lead and the enameled wire are used as two electrodes of the electric probeand after passing the inspection, a high-sensitivity shock wave measurement-used electric probe is achieved. The electric probe has good shock wave response, the response time can reach a nanosecondorder, the response range is wide from a dozen GPa to hundreds of GPa, the size is small, the mounting steps are simple, the use is convenient, the making cost is low, and the research cost can be significantly reduced.

Description

technical field [0001] The invention belongs to the field of shock wave measurement devices, and in particular relates to an electric probe for shock wave measurement and a manufacturing method thereof, more precisely, relates to a high-speed pulse electric switch element for monitoring shock wave fronts or moving objects The component whose surface reaches a predetermined position and its manufacturing method. Background technique [0002] In shock wave physics and partial detonation physics experiments, the dynamic impact angle of flyers, shock wave velocity and wave front inclination are often measured with electric probes. The dynamic collision angle of the flyer refers to the angle between the plane of the flyer and the target plane, which reflects the approximation of the uniaxial collision; Flyer dynamic collision angle influence. In the impact experiment, the electric probe is connected to the electric pulse network circuit as a high-speed pulse electric switch. B...
