High-voltage switching device for potential therapeutic instrument

Abstract

The invention provides a high-voltage switching device for a potential therapeutic instrument. The high-voltage switching device comprises a plastic shell, a spring base is mounted at the center of the bottom of the plastic shell, a spring is fixed on the spring base, a spring cap is fixed at the top of the spring, a magnetic induction device is mounted at the center of each of front, rear, left and right side faces of the plastic shell and comprises a connection piece, each connection piece is fixed on the inner side of the plastic shell through a left metal fixing column and a right metal fixing column, the outer end of each metal fixing column penetrates the plastic shell to be connected with a high-voltage line outside the plastic shell, a magnetic induction coil fixing seat is fixed outside the plastic shell through screws, and a magnetic induction coil is fixed on the magnetic induction coil fixing seat. Four-hole output of a high-voltage port of the potential therapeutic instrument is combined into one-hole output by adopting the electric-to-magnetic principle, utilizing adsorption technology and enabling a high-voltage lead to be on, the problem of electric arc interferenceis solved, and independent control of functions is realized.

Description

technical field [0001] The invention relates to a high-voltage switching device, in particular to a high-voltage switching device used in a potential therapy instrument. Background technique [0002] Potential therapeutic equipment generally has functions such as high potential, negative potential, and intermediate frequency electric field. Its function uses relays for high-voltage switching, and then outputs different functions through different high-voltage ports. Here, the relay is similar to an electrical contact switch device. [0003] The relay (electromagnetic type) is generally composed of an iron core, a coil, an armature, and a contact reed. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect. The moving contact and the static contact (normally open contact) are sucked together. When the coil is de-energized, the electromagnetic suction force will also disappe...

AI Technical Summary

Problems solved by technology

The use of relays in potential therapy devices has the following disadvantages: a relay is equivalent to a switch, controls a function, and cannot realize multi-function selection

[0006] Defect 1: The rotating mechanism is driven by a motor. The accuracy of the motor directly affects the accuracy of the rotating mechanism's position. The final result of this problem is that the input PIN pin and the output PIN pin are in poor contact, no conduction, and the product has no power supply output.

[0007] Defect 2: The contact area between the input PIN pin and the output PIN pin, the size of the area directly affects the stability of the power supply output of the product
