Capacitor insulation cover produced from waste electrical polypropylene film

Abstract

The invention relates to a capacitor insulating cover made of a waste electrotechnical polypropylene film. A cover body is made of the waste electrotechnical polypropylene film. The lower end of the cover body is provided with a cavity, two terminals at the top of a capacitor can be inlaid in the cavity, the inner side of the side wall of the cavity is provided with clamping rings, the clamping rings are used for being fixed on the terminals of the capacitor in a sleeved mode, the inner wall of each clamping ring is in a circular arc shape, the top of the cover body is provided with through holes, corresponding terminal leads can pass through the through holes, and casing pipes upwards protruding are arranged at the upper end of the cover body and surround the through holes. The spacing distance between the leads keeps stable, the leads are effectively prevented from being wound, reduction of the insulating performance due to decreasing of the creep distance caused when the leads are heated and shrink or when animals bite through the wire skin can be effectively prevented, and the safety performance of the capacitor is enhanced. Meanwhile, the capacitor insulating cover made of the waste electrotechnical polypropylene film is simple in structure, convenient to machine and low in cost.

Description

technical field [0001] The invention relates to an external insulating device for capacitors, in particular to a capacitor insulating cover produced from waste electrical polypropylene film. Background technique [0002] Usually, there are two lead-out terminals on the top of the lamp capacitor or AC capacitor, and each terminal is connected to an external lead wire with insulating rubber, such as the CBB65 capacitor produced by Anhui Tongfeng Electronics Co., Ltd. This kind of capacitor is easy to be entangled with each other due to the short distance between the two leads. The rubber is easy to age and lose its insulating effect, resulting in discharge between the two poles of the capacitor and a short circuit; at the same time, the lead wire at the lead-out end of the capacitor is exposed to the copper core wire due to high temperature shrinkage during use; or the animal bites the wire skin, etc., the capacitor The short distance between the two poles can easily lead to ...
