Embodiment 1

[0026] see figure 1 , a tantalum capacitor, including an inner shell 1 and an outer shell 2, the outer shell 2 covers the outside of the inner shell 1, a group of mutually symmetrical front plates 11 and rear plates 12 are respectively installed on the four side walls of the inner shell 1, and the inner wall of the outer shell 2 There is a limit rod 21 that runs through the front plate 11 and the rear plate 12. The outside of the housing 2 is also coated with epoxy resin 23. The limit rod 21 is fixed on the outer wall between the front plate 11 and the rear plate 12. The middle plate 22 connected to the outer shell 2, the spring 3 that is sleeved on the limit rod 21 is connected between the middle plate 22, the front plate 11 and the rear plate 12, and the setting of the spring 3 can make the connection between the inner shell 1 and the outer shell 2 An elastic connection method is formed. When a large relative shaking may occur between the inner shell 1 or the outer shell 2, ...

Embodiment 2

[0036] see figure 2 The inner shell 1 and the outer shell 2 in the aluminum capacitor are components made of aluminum material, the epoxy resin 23 is filled inside the inner shell 1 and the outer shell 2, and the positive terminal electrode 4 and the negative terminal electrode 5 are connected to the outer wall of the shell 2.

Abstract

The invention discloses a tantalum and aluminum capacitor and a preparation method thereof. The tantalum and aluminum capacitor comprises an internal shell and an outer shell, the outer part of the inner shell is covered by the outer shell, and four side walls of the inner shell are respectively provided with a group of front plate and rear plate which are symmetrical to each other. A limiting rodpenetrating through the front plate and the rear plate is arranged on the inner wall of the outer shell, the outer part of the outer shell is also coated with epoxy resin, and a middle plate connected with the outer shell is fixed to the outer wall, located between the front plate and the rear plate, of the limiting rod. According to the present invention, springs sleeving the limiting rods are connected between the middle plate and the front plate and between the middle plate and the rear plate; the inner shell and the outer shell can be connected in an elastic connection mode through the springs additionally arranged on the tantalum capacitor; with the absorption effect between the springs, the vibration kinetic energy is absorbed; a conduction polymer based on bisamide bond hydrogen bond enhancement is added into an aluminum capacitor and covers the surface of an oxide film, the hydrogen bonds can be damaged and recombined in the heating and cooling process, and the mechanical property and the electrical property of the capacitor are recovered, so that the safety of the capacitor is improved, and the service life of the capacitor is prolonged.

Description

technical field [0001] The invention relates to a tantalum and aluminum capacitor and a preparation method, in particular to a tantalum and aluminum capacitor and a preparation method thereof. Background technique [0002] The full name of tantalum capacitor is tantalum electrolytic capacitor, which is also a kind of electrolytic capacitor. It uses metal tantalum as the medium and does not use electrolyte like ordinary electrolytic capacitors. Tantalum capacitors do not need to use aluminum-coated capacitor paper winding The control itself has almost no inductance, but this also limits its capacity. In addition, since there is no electrolyte inside the tantalum capacitor, it is very suitable for working at high temperature, high temperature resistance, high accuracy, and excellent performance in filtering high-frequency harmonics. [0003] An aluminum electrolytic capacitor is made of an aluminum cylinder as the negative electrode, which is filled with a liquid electrolyte,...
