Capacitor element protection box

Abstract

The invention discloses a capacitor element protection box which structurally comprises a top cover, a sliding rod, a placement box and heat dissipation holes, the lower end of the top cover is in sliding connection with the sliding rod, the sliding rod is fixedly installed at the top of the placement box, a square capacitor abuts against a bottom supporting plate, meanwhile, a swing plate swings in an arc shape, it is ensured that the square capacitor is smoother when the square capacitor is lowered, and the square capacitor is prevented from colliding with the inside of a placing groove; a downward pressing rod is pressed downwards in a conduction air pipe, an air thin film is bulged under air pressure, the bulged air thin film buffers and supports the bottom of the square capacitor which is put down, and the surfaces of the two sides of the right-angle end of the square capacitor abut against rubber blocks; and then the bottom of the right-angle end of the square capacitor presses a lower pressing plate, at the moment, a linkage plate drives a sliding block at the lower end to slide stably on a guide rod, buffering is conducted through a compression spring, the effect of buffering and supporting the bottom of the right-angle end of the square capacitor is achieved, and shaking and collision of the bottom of the right-angle end of the square capacitor are avoided.

Description

technical field [0001] The present invention relates to the field of capacitors, and more specifically, relates to a capacitor element protection box. Background technique [0002] In comparison, square power capacitors are traditional and have a long history. Many projects used square capacitors before. Most square capacitors are covered with metal shells. When not in use, square capacitors need to be protected. Store it in a box to prevent bumps and damage at the right angles of the square capacitor. However, the protective box needs to use a relatively hard material to play a protective role. In the process of removing the square capacitor inside the protective box, the square The right-angled edges around the capacitor are prone to greater wear and tear on the inner wall of the protective box. At the same time, when the protective box is moving, the bottom of the square capacitor inside is likely to shake with the movement, which will easily cause damage to the right-ang...

When not in use, square capacitors need to be protected. Store it in a box to prevent bumps and damage at the right angles of the square capacitor. However, the protective box needs to use a relatively hard material to play a protective role. In the process of removing the square capacitor inside the protective box, the square The right-angled edges around the capacitor are prone to greater wear and tear on the inner wall of the protective box. At the same time, when the protective box is moving, the bottom of the square capacitor inside is likely to shake with the movement, which will easily cause damage to the right-angled edges of the square capacitor and reduce the The thickness of the metal shell of the square capacitor will destroy the performance of the square capacitor
