Abstract
The invention relates to a thermal protector. The thermal protector comprises a shell, a base and a base board, wherein the base and the base board are arranged in the shell; the base is fixedly connected with two wires; one wire is connected with a static contact piece, and the other wire is connected with a bimetal element arranged on the base board; the bimetal element is connected with a movable contact through a spring piece; the movable contact is contacted with the static contact piece; the shell is a ceramic shell; and the surface of the shell is glazed. The thermal protector has the advantages of water proofing and temperature resistance.
Description
Technical field
The present invention relates to a kind of thermal protector.
Background technology
Thermal protector is widely used in the domestic air conditioning motor; the dishwasher motor; the electric fan motor; the protection of household electrical appliance such as motor's for washing machine, motor; also can be used for the overtemperature protection of notebook computer, mobile phone, portable equipment simultaneously; this thermal protector also can be used for electric heating appliance, fluorescent lamp ballast, transformer, automobile motor, automobile heating seat cushion, and the overheated overheat protector of pump motor, novel auxiliary electrical heating solar water heater and general electric equipment can be installed at narrow space.The producer of domestic production thermal protector all adopts plastic casing and metal shell; adopt metal shell and plastic casing; the limitation of using is too big; metal shell can not be used in dishwasher motor and pump motor; the auxiliary electrical heating solar water heater; product is subjected to behind the water very easily that oxidation makes product ineffective, and the product of plastic casing can only be used for the plastic packaging motor, and temperature requirement is lower.
Summary of the invention
The objective of the invention is: the thermal protector that a kind of waterproof heatproof is provided.
The object of the present invention is achieved like this: a kind of thermal protector; comprise shell; base and base plate are set in the shell; fixedly connected two leads on the base, wherein a lead connects static contact, and another root lead connects the bimetallic element that is arranged on the base plate; bimetallic element connects moving contact by spring leaf; and moving contact contacts with static contact, and described shell is a ceramic package, and case surface adds glaze.
The present invention is a temperature-sensing element with the bimetal leaf, adopts the heat protector outer casing of 95% ceramic material, is applicable to any occasion, can not produce oxidation after being subjected to water, the heatproof height, and thermal protector ceramic package surface adds glaze, can use in water for a long time.
The invention has the beneficial effects as follows can the waterproof heatproof.
In order to reach better waterproof effect, epoxy sealing glue is filled in the junction of described lead and shell.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Wherein, 1-lead, 2-shell, 3-base, 4-moving contact, 5-spring leaf, 6-bimetallic element, 7-base plate, 8-static contact, 9-epoxy sealing glue.
