Capacitor convenient to weld

Abstract

The invention discloses a capacitor convenient to weld. The capacitor comprises a capacitor body, wherein a capacitor core is fixed inside the capacitor body by virtue of a capacitor core fixing ring,the surface of the capacitor core is coated with an aluminum protective shell, the surface of the aluminum protective shell is provided with an arc groove, the upper end of the capacitor core is connected with a first fuse wire and a second fuse wire by virtue of a first lead strip and a second lead strip, the top end of the first fuse wire is connected with a first lead terminal, the top end ofthe second fuse wire is connected with a second lead terminal, an explosion-proof cover plate is arranged above the capacitor core, and a space between the explosion-proof cover plate and the capacitor core is filled with a damp-proof encapsulating material. The capacitor is first provided with a welding pin, the diameter of the welding pin is smaller than the lead terminal, and during welding, the welding pin can be inserted into a jack of a circuit board, so that the first lead terminal and the second lead terminal can be welded, and the capacitor is more convenient to weld.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a capacitor that is convenient for welding. Background technique [0002] Capacitors, usually referred to as capacitance for their ability to hold charges, are represented by the letter C. Capacitors, as the name implies, are 'charged containers', which are devices that hold charges. Capacitors are one of the electronic components widely used in electronic equipment. It is widely used in DC blocking, coupling, bypass, filtering, tuning circuit, energy conversion, control and other aspects in the circuit. In the DC circuit, the capacitor is equivalent to an open circuit. A capacitor is a component that can store electric charge and is one of the most commonly used electronic components.

Problems solved by technology

[0003] There are many types of capacitors on the market at present. When some poor-quality capacitors are used, they will expand when they are heated, which will cause the aluminum protective shell of the capacitor to expand and damage, resulting in damage to the capacitor. Secondly, the lead terminals and welding holes of the capacitors currently on the market The same inner diameter, not convenient enough for welding
