Description

Technical Field

[0001] The utility model specifically relates to the technical field of thermal protectors, in particular to an embedded thermal protector. Background Art

[0002] A thermal protector is a thermostat that uses three metal plates as temperature sensing elements. When the temperature drops to the set temperature, the contacts automatically close and open to restore normal working conditions. It is widely used in household electrical motors and electrical equipment, such as washing machine motors, air conditioner fan motors, transformers, ballasts, electric heating appliances, etc.

[0003] After being connected to the line, the traditional thermal protector is fixed to the installation carrier through which the line passes by bolts. It cannot be embedded on the inner side of the installation object or in the installation groove of the installation carrier, and it protrudes and is exposed on the outside. For this reason, we provide an embedded thermal protector, which is connected to the extension rod by sliding on the inner side of the guide tubes on both sides, and with the cooperation of the spring, it can be embedded in different installation grooves according to actual conditions. It is embedded on the inside and will not be exposed on the outside, which also has a protective effect on the thermal protector. Secondly, it is more convenient to install, which effectively compensates for the above problems. Utility Model Content
