Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of thermostat with function of preventing low temperature connection.The present invention processes simply, and cost is low, can reach the effect than the Long-distance Control product temperature, has temperature control effect accurately, and can stop because of ambient temperature and cross the low bi-metal plate deformed that makes, and prevents that effectively the contact from connecting once more, has avoided hidden danger.
For reaching above-mentioned purpose, the present invention adopts following technical scheme:
A kind of thermostat with function of preventing low temperature connection, comprise support, regulating shaft and insulated column are installed on the support, be separately installed with binding post, the fixed contact sheet of spring leaf, moving contact sheet, binding post, bimetal leaf and the lug plate of fixed contact sheet on the insulated column from top to bottom, and between support and the spring leaf, between the binding post of moving contact sheet and the fixed contact sheet, fit is equipped with the porcelain packing ring on the binding post of fixed contact sheet and the insulated column between the bimetal leaf; Be installed with porcelain knob between spring leaf and the bimetal leaf; Be fixed with the moving contact sheet on the spring leaf, the moving contact sheet is provided with moving contact, and the fixed contact sheet is provided with fixed contact; The below of described fixed contact sheet is welded with a slice heating wire, and the binding post of heating wire one end and fixed contact sheet is connected, and the other end and fixed contact sheet are connected; Between the binding post of fixed contact sheet and fixed contact sheet mica sheet is installed; The below of bimetal leaf is installed with an iron plate, and micrometer adjusting screw is installed on the iron plate.
The length of described heating wire is the 5-20 millimeter, and wide is the 1.0-5.0 millimeter, and thickness is the 0.1-0.4 millimeter.
The binding post welding of described heating wire one end and fixed contact sheet is connected, and the other end and the welding of fixed contact sheet are connected.
Described mica sheet thickness is the 0.5-1.0 millimeter.
The invention has the beneficial effects as follows: the present invention processes simply, and cost is low, can reach the effect than the Long-distance Control product temperature, has temperature control effect accurately, and can stop because of ambient temperature and cross the low bi-metal plate deformed that makes, prevent that effectively the contact from connecting once more, avoid hidden danger.
