The feature of the automatic reset type product is to keep the temperature of the load within a certain range, that is, it will not permanently protect the load due to the sharp rise in temperature after the load fails. Once the load temperature drops to a certain range, the protector will automatically connect again. The failure of the load has not been resolved at all, which virtually increases the risk of use

The invention provides a locking-type manual reset protector with an insulation sheet and belongs to a composite type over-current and overheat protector. The locking-type manual reset protector comprises a shell. The shell is internally provided with a first lug plate and a second lug plate which are respectively riveted to the shell. The outer end of each of the first lug plate and the second lug plate is arranged outside the shell, the second lug plate is lower than the first lug plate in position, a bimetal sheet is fixedly connected on the upper side of the inner end of the first lug plate, a fixed contact is arranged on the inner end of the second lug plate, a movable contact is arranged on the free end of the bimetal sheet, and the fixed contact and the movable contact are in mutual contact with each other. A push rod is arranged inside the shell, one insulation sheet is connected on the inner end portion of the push rod, and a reset spring is arranged between the push rod and the shell. When the protector is disconnected, the insulation sheet is arranged between the fixed contact and the movable contact; when the protector resets, the insulation sheet leaves the fixed contact and the movable contact and is located in the compression direction of the reset spring. The locking-type manual reset protector is simple in structure, convenient to use and high in security coefficient.
Description
technical field [0001] The invention belongs to a composite overcurrent and overheating protector, in particular to an overheating and overcurrent protector for generators, electric motors, rotating motors of household appliances, electric appliances, electric heating appliances, lighting appliances, communication equipment, and instruments, and the like. Temperature control device. Background technique [0002] At present, most of the protectors on the market are automatic reset. It is not convenient for customers to apply in different environments. The feature of the automatic reset type product is to keep the temperature of the load within a certain range, that is, it will not permanently protect the load due to the sharp rise in temperature after the load fails. Once the load temperature drops to a certain range, the protector will automatically connect again. The failure of the load has not been resolved at all, which virtually increases the risk of use.
