Abstract
The utility model relates to an electric appliance switch which is controlled by the water temperature variation, particularly a temperature-controlling switch of an automotive radiator fan. The utility model comprises a case body, a bimetal piece 4, a dynamic piece 11 and a fixed seat 6 of a fixed piece 10, wherein, the bimetal piece 4 is arranged in the case body; the dynamic piece 11 is in driving connection with the bimetal piece; the fixed piece 10 is matched with the dynamic piece; a screw thread connecting structure and an adhesion positioning structure are arranged between the fixed seat and the case body; after the distance between a screw thread regulating dynamic piece and the bimetal piece reach the requirement, the screw thread regulating dynamic piece and the bimetal piece can be adhered and sealed. The temperature-controlling switch has stable control indexes and high using reliability.
Description
The utility model relates to the appliance switch, the particularly temperature detect switch (TDS) of radiator fan that utilizes water temperature to change enforcement control.
The temperature detect switch (TDS) of existing radiator cooling fan is made of housing and interior bimetal leaf thereof, elasticity moving plate and push rod, linked fan and moving plate between stator, bimetal leaf and the moving plate and the lead of stator etc. on the holder.Temperature detect switch (TDS) is installed on the radiator, make bimetal leaf acumen experience water temperature, when water temperature was elevated to setting value, the deflection of bimetal leaf reached the promotion push rod and moving plate and stator is joined, promptly connect fan power supply, water tank is brushed in the starting fan operation, its water temperature is descended, when water temperature is reduced to setting value, bi-metal plate deformed is restored, push rod resets with moving plate, and moving plate leaves stator, and fan power supply disconnects out of service.The holder of this temperature detect switch (TDS) is contained in the tube chamber portion of housing, is relation movingly with the tube chamber, and tube wall termination, the chamber face of button is packed in holder in the chamber in utilizing.Therefore, moving plate connect distance between push rod and the bimetal leaf and moving plate thereof to push rod give the inaccessible designing requirement of pressure, make control index error, the dependability of temperature detect switch (TDS) poor.
Given this, the purpose of this utility model just is to provide a kind of temperature detect switch (TDS) that index is stable, dependability is high of controlling.
Temperature detect switch (TDS) of the present utility model (referring to accompanying drawing), comprising housing (1) and interior bimetal leaf (4) thereof, the holder (6) of moving plate (11) that links with the bimetal leaf transmission and the stator (10) that matches with moving plate is arranged, is thread joined structure and bonding location structure between said fixing seat and housing.
Characteristics of the present utility model and advantage be, connecting between holder and the housing is thread joined structure, promptly is the adjustable draw bail in a kind of position in the axial direction.Holder is rotated the tube chamber portion of the housing of packing into, and the distance between holder and push rod, bimetal leaf is adjusted in rotation, make the distance between moving plate on the holder and push rod, the bimetal leaf, moving plate adheres to specification to the pressure that gives of push rod, bimetal leaf, then with holder and the bonding location of housing.The utlity model has the advantage that the control index is stable, dependability is high thereby make.
Below, use embodiment and accompanying drawing thereof again, the utility model is described in further detail.
Brief description of drawings.
Fig. 1 is the structural representation of a kind of temperature detect switch (TDS) of the present utility model.
Fig. 2 is the schematic top plan view of the holder 6 of Fig. 1.
Fig. 3 is the A-A cross-sectional schematic of Fig. 2.
Embodiment 1
A kind of temperature detect switch (TDS) of the present utility model, as shown in the figure.Housing 1 is arranged, housing is made tubular with metal material, its front end is for there being externally threaded closed cylinder portion 2, be pressed with the bimetal leaf 4 of common temperature sensitive type in it with guide ring 3, the afterbody of housing is that tube chamber portion 5, its internal chamber wall that periphery is hex nut shape has internal thread, with thread joined structure holder 6 is housed.This holder periphery is shaped on screw thread 7, on its ladder bottom surface with two binding posts 8,9 respectively rivet clasp the stator 10 and the resilient moving plate 11 of electric conducting material system are arranged, moving plate 11 is lifted up tongue 12, and its end riveting has the contact of matching with the contact of moving plate, and the gap of design code should be arranged between two contacts.The cylindrical push rod 13 of the ceramic that places guide ring 3 central parts is arranged between moving plate 11 and bimetal leaf 4.Rely on screw thread 7 that the holder spinning is gone into the tube chamber portion 5 of housing, adjustment adheres to specification it.Form bonding part 14 with adhesive then, the Connection jacket 15 of annular is packed in the housing tail end, thus the positioning and fixing seat.With lead 16,17 respectively with binding post 8,9 weldering connection after, with resin 18 fillings encapsulation Connection jacket, make this temperature detect switch (TDS).
Rely on the screw thread of this temperature detect switch (TDS) closed cylinder portion 2, this temperature detect switch (TDS) be installed in the setting position of radiator, make closed cylinder portion directly and the water in the water tank contact.Utilize the distortion of bimetal leaf with water temperature, promote push rod, make moving plate contact or be separated with stator, through the link break-make of fan power of lead 16,17 controls, realization is to the control of electric fan.
Claims (1)
1, temperature detect switch (TDS), comprise housing (1) and interior bimetal leaf (4) thereof, the holder (6) of moving plate (11) that links with the bimetal leaf transmission and the stator (10) that matches with moving plate is arranged, it is characterized in that between holder and housing being thread joined structure and bonding location structure.
