High-temperature-resistant bolt-type aluminum electrolytic capacitor

Abstract

The invention belongs to the technical field of capacitors and particularly discloses a high-temperature-resistant bolt type aluminum electrolytic capacitor. The capacitor comprises a shell, a cavity is formed in the shell, and a core is fixed in the cavity; a top end and a bottom end of the outer side face of the shell are each provided with at least two air inlets, and filtering assemblies are detachably fixed into the air inlets; the outer side face of the core is sleeved with a heat conduction sleeve, the outer side face of the heat conduction sleeve is fixedly connected with a plurality of heat conduction modules, and two ends of the heat conduction sleeve are fixed to the top end and the bottom end of the cavity correspondingly; a transmission assembly is arranged at a bottom end of the shell and is in transmission connection with a plurality of threaded rods, and one end of each threaded rod penetrates through the cavity and is fixedly connected with a sweeping block. Through the arrangement of the filtering assembly and the heat conduction module, technical problems that in the prior art, the heat dissipation effect of a capacitor is poor, and dust or sundries are prone to entering are effectively solved, and then the technical effects that the heat dissipation effect of the capacitor is improved, and dust or sundries are prevented from entering are achieved.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a high temperature resistant bolt type aluminum electrolytic capacitor. Background technique [0002] Capacitors are an important electronic component in electronic devices. The quality of the capacitor directly affects the quality and market competitiveness of the entire electronic product. With the rapid development of electronic technology, people's requirements for capacitors are becoming more and more stringent. In the structure of existing capacitors, the widths of the positive electrode foil and the negative electrode foil are generally set to be smaller than the width of the electrolytic paper, so that the positive electrode foil and the negative electrode foil are completely overlapped. However, due to the defects in processing equipment and processing technology, in the actual production process, due to the relatively large amount of material used in the bolt type ...
