Title:
TEMPERATURE CUT OFF BREAKER
Document Type and Number:
WIPO Patent Application WO/2017/125068
Kind Code:
A1
Abstract:
A temperature cut off breaker, comprising: a bimetal switch (101, 102); an insulation package (130), wherein the bimetal switch is packaged in the insulation package; and a pair of electrode pins (110, 120), which are respectively electrically connected to two ends of the bimetal switch. An insulation coating (140) is formed on at least a portion, extending from the insulation package, of the pair of electrode pins; and the insulation coating is made of a curable material, the curing temperature of which is lower than the triggering temperature of the temperature cut off breaker. The insulation coating is accurately formed on a region, needing to be insulated, of the electrode pins and is reliably combined with the electrode pins, and thus a short circuit can be reliably prevented from occurring between electrode pins of a thermal protection device, and the usage security is improved. In addition, the cost of the insulation coating is lower than that of a common insulation tap, and therefore, the manufacturing cost of a thermal protection device is reduced. Furthermore, an automatic spraying device can be used to efficiently form the insulation coating, so as to improve the manufacturing efficiency.
