Electrolytic capacitors with explosion-proof function

Abstract

The invention relates to an electrolytic capacitor with an explosion-proof function. The electrolytic capacitor settles problems such as low fixing effect in an existing capacitor. The electrolytic capacitor comprises a capacitor housing, a sleeve, an end cap, a capacitor core package, two terminal blocks, wring bolts and a detachable positioning structure. An external screw thread exists on the circumferential external surface of the capacitor housing. An annular collar sleeves the lower end of the capacitor housing. The circumferential inner side of the annular collar is provided with an internal screw thread. Furthermore the annular collar and the capacitor housing are connected in threaded connection. One side, which is next to the lower end of the capacitor housing, of the annular collar is circumferentially provided with a plurality of extension bases that face the circumferential inner side of the annular collar. The extension bases extend to the circumferential inner side of the annular collar and are crossed with one another at the center of the annular collar. The crossing portion of each extension base is provided with a positioning hole. Furthermore a positioning column is connected with the positioning sleeve through the detachable positioning structure. The electrolytic capacitor has advantages high explosion-proof effect of the capacitor, high convenience in mounting and fixing the capacitor, no easy loosening between the positioning column and the capacitor housing, and higher firmness in mounting and fixation.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, in particular to an electrolytic capacitor with explosion-proof function. Background technique [0002] Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. 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. Classification by electrolyte: organic dielectric capacitors, inorganic dielectric capacitors, electrolytic capacitors, electric heating capacitors and air dielectric capacitors, etc. Among them, electrolytic capacitors are being widely used because of their large capacity and ability to withstand large pulsating currents. The existing electrolytic capacitors are mostly installed by the mounting base that comes with the capacitor. This installation method has many ...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves the problem of looseness between the bolt and the capacitor when the existing capacitor is installed to a certain extent, but because the capacitor is actually installed in the structure of the scheme, it can only be installed by rotating the capacitor or fixing the capacitor, so it is easy to make the capacitor The shell is deformed, and the capacitor in this scheme still exists: the explosion-proof effect is poor, and the problem of looseness between the terminal end and the end cover is easy to occur during wiring
