Problems solved by technology

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 loses its insulating effect, resulting in discharge between the two poles of the capacitor and a short circuit; at the same time, the lead wire 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 a sudden drop in electrical insulation strength, creepage, or even a short circuit, resulting in a decrease in safety performance

Embodiment Construction

[0012] like figure 1 , figure 2 and image 3 As shown, the cover body 1 is made of waste electrical polypropylene film; the lower end of the cover body 1 has a cavity 3 for the two terminals on the top of the capacitor to be embedded, and the inner side of the cavity side wall 1 is provided with a socket for fixing on the capacitor terminal through a sleeve. The inner wall is arc-shaped snap ring 6 .

[0013] There are through holes 5 on the top of the cover body 1 for the lead wires of the corresponding terminals to pass through. The upper end of the cover body 1 is provided with an upwardly protruding sleeve 4 around each through hole 5, and the height of the sleeve tube 4 is 3-5mm.

[0014] Considering the convenience of fixing, the cover body 1 is provided with two symmetrical snap rings 61, 62 corresponding to each terminal inside the cavity side wall 2, and the arc length of each snap ring 61, 62 is not less than л / 6. When the cover covers the terminals, two snap rin...

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 close 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 ...
