The bimetallic strip temperature controller can be connected with an earth wire directly, is convenient in installation, and protects the using safety of electric appliances.
Description
Technical field
The utility model relates to temperature automatic control technology field, in particular, relates to a kind of bimetal strip thermostat.
Background technology
First connection terminal in the visible in the market temperature adjustment bimetal strip thermostat is connected with live wire, the zero line of electrical equipment respectively with second connection terminal, but because all can there be the potential safety hazard of electric leakage in electrical equipment, general electrical equipment all need draw ground wire, aims at this and increases many costs; Simultaneously, also must consider to arrange the safe and reasonable that whether walks of circuit.
In addition, the hinged end of bimetallic strip is away from heater, because the heat of heater can not in time be transmitted to bimetallic strip, crosses and penetrates so can produce big temperature.
Summary of the invention
The purpose of this utility model has been to provide a kind of device of setting up ground wire, thereby but can be safe in utilization at when electric leakage protection electrical equipment and the temperature controller of sensitive ground wire.
The technical solution of the utility model is:
A kind of bimetal strip thermostat, comprise and be used to connect first connection terminal and second connection terminal that extraneous power supply forms the loop, be positioned at the thermometal thermal sensitive piece assembly of temperature controller lower end, upper plate assembly and be installed on regulating device on the upper plate, the shell fragment assembly that contacts with regulating device.Also comprise the 3rd connection terminal, the 3rd connection terminal is electrically connected with the rivet made from conductive material.
Preferably, the lower surface of bimetallic strip structure is provided with thermal conductive metal plate.
Preferably, the hinged end of bimetallic strip structure is positioned near on the position of conducting strip.
Positive progressive effect of the present utility model is: owing to set up the 3rd connection terminal, the 3rd connection terminal is electrically connected with the rivet made from conductive material.The 3rd connection terminal can directly connect ground wire, and is easy for installation, protected the safe in utilization of electrical equipment.

Embodiment
Extremely shown in Figure 5 as Fig. 1:
But the temperature controller of the utility model ground wire has comprised thermometal thermal sensitive piece assembly 15, contact chip assembly 14, the first connection terminals 32, the second connection terminals 31, the three connection terminals 30, and top plate member and regulating device 16.
Wherein, first connection terminal and second connection terminal are connected to form the loop with extraneous power supply.
Thermometal thermal sensitive piece assembly is positioned at the temperature controller lower end, and the upper plate assembly is in the temperature controller upper end.And regulating device 16 is installed on the upper plate 11, and shell fragment assembly 10 contacts with regulating device.The 3rd connection terminal 30 is connected with the rivet made from conductive material 1.The lower surface of thermometal thermal sensitive piece assembly 15 is provided with thermal conductive metal plate 5, and its hinged end is positioned near on the position of conducting strip 5.Such setting can improve the sensitivity of reaction more near heater.
During use, temperature control rotating shaft 13 on the regulating device 16 is inwardly rotated, and drives long shell fragment 101 middle suspension shell fragments and moves inward, and drives short shell fragment 102, moving contact 91 on the short shell fragment 102 is communicated with stationary contact 92 on the contact chip 4, and electric heating appliance begins heat temperature raising.
When rising to design temperature, temperature transfers heat on the thermometal thermal sensitive piece 7 by the conducting strip 5 that is welded in rivet 1 bottom, thermometal thermal sensitive piece 7 heated bendings, the one side that drives shell fragment assembly 10 by porcelain pin 81 is bent upwards, moving contact 91 on the short shell fragment 102 is separated with stationary contact 92 on the contact chip 4, thereby disconnecting circuit stops heating.
When electrical equipment generation electric leakage situation, thereby the electric current of revealing on the electrical equipment can be transmitted to the 3rd connection terminal 30 and passes to the earth by ground wire by being fixed on rivet 1 on the electrical equipment, has guaranteed the safe in utilization of electric heating appliance.
But the temperature controller of the utility model ground wire has increased grounding wire device guarantees the safe in utilization of electrical equipment.
