Problems solved by technology
The explosion-proof structure of the existing organic dielectric capacitor is realized by deforming and falling off the top cover of the shell when the capacitor body is deformed or exploded, and tearing off the connection between the top cover electrode and the capacitor body. After the explosion-proof capacitor is not repairable, resulting in waste of material resources

Embodiment Construction
[0014] like figure 1 as shown, figure 1 It is a structural schematic diagram of an explosion-proof capacitor proposed by the present invention.
[0015] refer to figure 1 , an explosion-proof capacitor proposed by the present invention, comprising: a capacitor body 3, a housing 1 for accommodating the capacitor body 3, an end cover 4, and a filling liquid 2; the filling liquid 2 is injected into the housing 1 outside the capacitor body 3 , the housing 1 is provided with an end cover 4;
[0016] The end cover 4 is provided with a first guide groove with the notch facing inward, and a first slider 41 that can slide back and forth in the first guide groove is arranged in the first guide groove;
[0017] The first terminal 43 and the second terminal 45 are installed on the end cover 4, and a first guide groove is opened on the first terminal 43, and the first guide groove and the first through groove penetrating through the housing 1 Connecting to form a second guide groove, a...

The invention discloses an explosion-proof capacitor. After the explosion-proof capacitor is operated for a long time, the capacitor body heats and enables a filling liquid to be heated and expanded,the pressure in a shell rises, and the filling liquid pushes a first sliding block to slide towards the outer side of the shell so as to reduce the pressure inside the shell; the first sliding block slides towards the outer side of the shell and drives a second sliding block to slide, so that a first conductive part on the second sliding block is separated from a second conductive part on a firstbinding post, and the first binding post is in a power-off state and enables the capacitor to stop working; the capacitor body does not generate heat after the capacitor body stops working, the filling liquid is cooled and shrunk, and the pressure in the inner part of the shell is reduced; therefore, the capacitor is prevented from being exploded, and the explosion-proof effect is achieved; and compared with a capacitor in the prior art, the explosion-proof effect of which is achieved by damaging the shell, the explosion-proof capacitor disclosed in the invention has a remarkable beneficial effect and the service life of the capacitor can be prolonged.
Description
technical field [0001] The invention relates to electronic components, in particular to an explosion-proof capacitor. 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. Classified by dielectric: organic dielectric capacitors, inorganic dielectric capacitors, electrolytic capacitors, electric heating capacitors and air dielectric capacitors, etc. Among them, organic dielectric capacitors are the most widely used due to their mature technology, high production efficiency, and good safety. The explosion-proof structure of the existing organic dielectric capacitor is realized by deforming and falling off the top cover of the shell when the capacitor body is deformed or exploded, and...
