Problems solved by technology

The disadvantages of the above-mentioned assembly operation method are: the plastic bracket adopts a built-in type, which increases the processing and material costs of the plastic bracket, and the operator is not convenient enough to operate, the labor efficiency is low, and capacitor cores are prone to occur during the assembly process. The plastic bracket falls off, which leads to the distortion and damage of the lead-out soldering piece, which makes the qualified rate of the product lower

Abstract

The invention discloses a metalized safety film layer stacked-type pulse capacitor, and the capacitor comprises a capacitor packet, a leading-out soldering lug, a plastic housing, and filling resin. The capacitor packet is disposed in the plastic housing, and the interior of the plastic housing is provided with the filling resin. One end of the leading-out soldering lug is connected with the capacitor packet, and the other end of the leading-out soldering lug is located outside the housing. The capacitor also comprises plastic glue for fixing the capacitor packet in the plastic housing. The capacitor packet is formed by the stacking of a metalized film, and the metalized film comprises a central film substrate, a first metal coating layer, a second metal coating layer, and a laminated film medium. The first and second metal coating layers respectively comprise a plurality of square blocks, and the positions of the square blocks of the first and second metal coating layers are corresponding to each other. The capacitor can reduce the size and increase the capacity, is stable at a large-current state, is not liable to be damaged by arcing and breakdown.

Description

technical field [0001] The invention relates to a metallized safety film laminated pulse capacitor, which belongs to the technical field of film capacitor product manufacturing. Background technique [0002] The pulse capacitor in the prior art mainly consists of a metal shell, a lead-out, an insulating seat, a capacitor core group, a cover plate, a positioning epoxy plate, and an impregnating agent. Or capacitor cores combined in series are wound from thin films with one-sided margins and one-sided metal layer thickening. The shortcomings of the above-mentioned capacitors are that they are large in size and small in capacity, and they are easy to catch fire and break down under the condition of high voltage and high current, which will cause the capacitor to heat up and cause damage to the capacitor. It needs to be improved, and there is also a risk of damage during actual use. In addition, most of the capacitor metallized films in the prior art are composite zinc-aluminu...
