Thin-film capacitor core and high-voltage explosion-proof thin-film capacitor

The utility model relates to the technical field of thin-film capacitor cores and high-voltage explosion-proof thin-film capacitors, in particular to a thin-film capacitor core and a high-voltage explosion-proof thin-film capacitor, which comprise a shell, a braid layer is wrapped on the peripheral end surface of the shell, and first chutes are transversely arranged on the end surfaces of the front, rear, left and right sides in the shell; sliding blocks are slidably connected to the interiors of the multiple sets of first sliding grooves, springs are connected between the end faces of one sides of the sliding blocks and the end faces of one sides of the interiors of the first sliding grooves, and fixing blocks are symmetrically arranged on the positions, located on the upper sides and the lower sides of the multiple sets of first sliding grooves, of the end faces of the front side, the rear side, the left side and the right side of the interior of the shell; the film capacitor core and the high-voltage explo
