Digital power capacitor

Abstract

The invention relates to the technical field of capacitors, in particular to a digital power capacitor, which comprises a capacitor main shell, wherein a core is fixedly connected to the interior of the capacitor main shell, outgoing lines are symmetrically and fixedly connected to the two sides of the outer surface of the front end of the core, and sealing mechanisms are symmetrically and fixedly connected to positions, close to the outgoing lines, of the outer surface of the front end of the capacitor main shell. According to the invention, the purpose of resin adhesive outflow is achieved by controlling sliding of a sliding plate, so that a fixing sleeve and a wiring pipe are bonded; and when a resin and a plastic insulation protection layer of an outgoing line are separated under the action of external factors such as stress and the like, treatment can be conducted in time, so that the sealing effect of the device is improved, the stable connection between the fixing sleeve and the outgoing line is ensured, the fixing effect on the outgoing line is improved, the situation that the outgoing line and the core are separated from each other due to the looseness of the outgoing line is prevented, and the service life of the capacitor is prolonged.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a digital power capacitor. Background technique [0002] Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. Definition 1: A capacitor, as its name implies, is a 'charged container', a device that holds charges. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. Definition 2: Capacitor, any two conductors (including wires) that are insulated from each other and are very close to each other form a capacitor. [0003] A Chinese patent discloses a cable-leading capacitor, the patent application number is CN200880000309.3, which includes a capacitor body with a capacitor core inside, and the upper end of the capacitor body has a welding spot for connecting the capa...

AI Technical Summary

Problems solved by technology

[0004] In order to seal and protect the electrical components such as the core in the capacitor case, and at the same time seal, protect and fix the outer edge of the lead-out wire (plastic insulating protective layer), the above-mentioned device is welded to the capacitor core by welding the lead-out wire arranged in the capacitor main case On the son, the connecting part of the lead wire and the protective ring is potted with epoxy resin, polyurethane and other resins. This sealing method is easy to cause the capacitor to expand with heat and contract with cold under special temperature conditions. Or with the swinging and pulling of the lead-out wire, the resin and the plastic insulating protective layer of the lead-out wire are easily separated after external factors such as stress, and the sealing effect cannot meet the requirements, and at the same time affect the fixing effect on the lead-out wire. Make the lead-out wire move, which will cause the lead-out wire and the core to separate from each other, making the capacitor unable to work normally
