Problems solved by technology

[0004] Because the shells of current mica capacitors are all made of plastic, long-term use in high-temperature environments will seriously reduce the service life of the capacitors, thereby affecting normal working conditions, and the machine that cuts the pins of the capacitors after the preparation is completed Most of the structure is more complicated and the cost is higher

Abstract

The invention discloses a high temperature resistant wound mica capacitor and a preparation method thereof. Metal foil, both sides of the top of the ceramic layer are fixedly connected with pins, the bottom ends of the pins penetrate the ceramic layer and the shell and extend to the inside of the shell, by setting the motor seat and the support plate on the second support frame, respectively Provide support for the servo motor and the electric telescopic rod, use the first clamping block and the second clamping block on the moving plate to clamp the mica capacitor, and then cooperate with the screw to drive the screw sleeve to make the shearing knife move towards the mica capacitor The side moves and contacts with the second clamping block, thereby shortening the stitches. This structure is relatively simple, so it is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a high temperature resistant wound mica capacitor and a preparation method thereof. Background technique [0002] Mica capacitors refer to capacitors that use natural mica as the medium in the middle of the capacitor. Its shape is mostly square, and its pressure resistance and performance are quite good. However, due to the influence of the dielectric material, the capacity of the mica capacitor cannot be made too large, and the cost is higher than other capacitors. The medium of the mica capacitor is a mica sheet, and the electrode has a metal foil type and a metal film type. The early mica capacitors were made of metal foil or silver-sprayed electrodes on the surface of the mica sheet, and then they were laminated according to the required capacity and then impregnated and pressed into the bakelite shell. Nowadays, a layer of silver electrodes is mostly covered on the mica...
