Shell type capacitor assembling method

Abstract

The invention relates to a shell type capacitor assembling method comprising the steps that a hollow shell is taken, position-limiting protrusions are processed at the two ends of the internal side wall of the shell, and a gap for electrode embedding is reserved between the two position-limiting protrusions of the same pair; a produced capacitor is taken, and the electrodes of the two ends of the capacitor are bent to be L-shaped; and the capacitor is inserted in the shell, and the capacitor is inserted in the shell after the electrodes of the two ends of the capacitor are respectively aligned with the gap between the corresponding position-limiting protrusions when insertion is performed so that assembling of the capacitor is completed. Advantages of the shell type capacitor assembling method are that when assembling is performed by utilizing the assembling method, the position-limiting protrusion are processed in the shell, and the electrodes of the capacitor are limited and guided by utilizing the position-limiting protrusion so that the installing position of the capacitor is guaranteed and the electrodes can be limited after completion of installation, and thus displacement of the capacitor main body can be avoided and subsequent use is not influenced.

Description

technical field [0001] The invention relates to the field of capacitor manufacturing, in particular to a shell-type capacitor assembly method. Background technique [0002] A capacitor is a component that can store electric charge and is one of the most commonly used electronic components. In a DC circuit, a capacitor is equivalent to an open circuit. The simplest capacitor consists of plates at both ends and an insulating dielectric (including air) in between. After electrification, the plates are charged to form a voltage (potential difference), but due to the insulating material in the middle, the entire capacitor is non-conductive. However, such a situation is under the premise that the critical voltage (breakdown voltage) of the capacitor is not exceeded. We know that any substance is relatively insulating. When the voltage across the substance increases to a certain level, the substance can conduct electricity. We call this voltage the breakdown voltage. Capac...

Problems solved by technology

[0004] At present, the film capacitors used in the market can only be used in some small circuits, and the waterproof and moisture-proof performance is not high, and for some working conditions that require high safety performance, a shell will be placed outside the capacitor , and poured a layer of epoxy resin to improve its flame retardant performance

[0005] When installing the capacitor into the case, it is found that due to the large number of capacitors, their sizes are inconsistent. If each specification of the capacitor is equipped with a type of case, it will not only cause trouble, but also reduce the cost. Higher, and if the same type of shell is used, for some small-sized capacitors, it is easy to shift in the shell after being assembled into the shell, which affects normal use
