Background
The thermal protector is a common electrical element, the safety of a circuit is directly influenced by the performance of the thermal protector, the existing thermal protectors disconnect the circuit by the action of the bimetallic strip when the ambient temperature reaches a certain value, and the disconnection temperature of the thermal protector with the structure is certain and cannot be adjusted.
Disclosure of Invention
An object of the utility model is to provide a accuse temperature thermal protector to solve foretell technical problem.
The technical scheme of the application is as follows: a temperature-control thermal protector comprises a shell, an insulating block, a conductive bottom plate and a bimetallic strip, wherein the conductive bottom plate is fixed at the bottom of the insulating block; one end of the bimetallic strip is fixed on the insulating block, the other end of the bimetallic strip is provided with a movable contact, a fixed contact matched with the movable contact is arranged on the conductive bottom plate, the insulating block, the conductive bottom plate and the bimetallic strip are arranged in the shell, the bimetallic strip and the bottom plate are connected with a lead, and the lead extends out of the shell; the lower part of the bimetallic strip is further provided with a spare insulator, guide posts are arranged on two sides of the spare insulator, the bimetallic strip is located between the two guide posts, an insulating slide block matched with the spare insulator is connected to the guide posts in a sliding mode, a bolt used for controlling the insulating slide block to move up and down is connected to the insulating slide block, and the bolt is in threaded connection with the shell.
Preferably, a groove is formed in the top end of the insulating sliding block, and the bottom end of the bolt extends into the groove and is provided with a first blocking body; and a second blocking body is arranged at the top end of the insulating sliding block, and the second blocking body limits the first blocking body in the groove.
Preferably, the bottom surface of the insulating slider is arranged in parallel with the corresponding bimetallic strip part; the top surface of the spare insulator is arranged in parallel with the corresponding bimetallic strip portion.
Preferably, the housing comprises a housing body with an opening at one end and an epoxy sealing body, and the epoxy sealing body seals the opening of the housing; the lead penetrates through the epoxy sealing body and is exposed out of the shell.
The utility model provides a thermal protector accuse temperature thermal protector has two kinds of using-way:
1. the bimetallic strip can freely deform between the standby insulator and the insulating slide block, and the disconnection temperature of the thermal protector is relatively low in the using mode;
2. move insulating slider down through the mode of screwing up the bolt and make insulating slider support the part that bimetallic strip corresponds on reserve insulator, form the second fixed point for the length of bimetallic strip to fixed point reduces, and it is bigger just to warp like this can make movable contact break away from the stationary contact, thereby just can break off two contacts under relatively higher temperature, thereby can improve hot protector disconnection temperature.
The temperature control thermal protector has the following advantages:
1. the disconnection temperature of the thermal protector can be adjusted, so that the requirements of people can be met;
2. the second fixed point can be started under the condition that the movable contact and the fixed contact are in poor contact, and the two contacts are compressed through the insulating sliding block to be used as a common thermal protector, so that waste is reduced.
Drawings
Fig. 1 is a schematic view of an internal structure of a temperature-controlled thermal protector provided by the present invention;
FIG. 2 is an enlarged view of FIG. 1 at A;
in the figure: the device comprises a shell body 1, an insulating block 2, a conductive bottom plate 3, a bimetallic strip 4, a movable contact 5, a fixed contact 6, a lead 7, an insulator 8, a guide post 9, an insulating slide block 10, a bolt 11, a groove 12, a first blocking body 13, a second blocking body 14 and an epoxy sealing body 15.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
The temperature control thermal protector has two use modes:
1. the bimetallic strip can freely deform between the standby insulator and the insulating slide block, and the disconnection temperature of the thermal protector is relatively low in the using mode;
2. move insulating slider down through the mode of screwing up the bolt and make insulating slider support the part that bimetallic strip corresponds on reserve insulator, form the second fixed point for the length of bimetallic strip to fixed point reduces, and it is bigger just to warp like this can make movable contact break away from the stationary contact, thereby just can break off two contacts under relatively higher temperature, thereby can improve hot protector disconnection temperature.
The temperature control thermal protector has the following advantages:
1. the disconnection temperature of the thermal protector can be adjusted, so that the requirements of people can be met;
2. the second fixed point can be started under the condition that the movable contact and the fixed contact are in poor contact, and the two contacts are compressed through the insulating sliding block to be used as a common thermal protector, so that waste is reduced.
In actual manufacturing, the position of the bimetallic strip corresponding to the insulating slide block is inclined, and therefore in the embodiment, the bottom surface of the insulating slide block is parallel to the corresponding bimetallic strip part; the top surface of the spare insulator is arranged in parallel with the corresponding bimetallic strip portion to adapt to the inclined surface.
