Description
Technical field
The utility model relates to the heat-sensitive actuating structure in a kind of thermostat.
Background technology
The existing electric connector that is used for cordless electric appliance, general all by a plug with its mutually the socket of fit form, socket usually and consuming device make one, plug is connected with power line, when making electrical appliance, power line on the plug connects power supply and as pedestal, the socket of making one with consuming device places on the plug, the work of promptly switching on, so just can be so that consuming device is broken away from the puzzlement of power line, very convenient, and it is safe and reliable, the patent No. is that the Chinese utility model patent " electrical cnnector " of CN00233024.5 discloses so a kind of electrical cnnector by socket and the mutual fit of plug, the binding post that annular is arranged in the socket, the elasticity electric contact point that combines with annular binding post in the described socket is arranged on the plug, the binding post of annular is by the inwall of conduction in the described socket, outer wall and intermediate insulation material layer are formed, each elasticity electric contact point on the plug has dead ring isolated, when plug combines with socket, each annulus wall in each elasticity electric contact point on the plug and the socket combines, avoid the generation of electric arc, each is organized all has dead ring isolated between the contact, and the contact of zero potential is between the phase line, connector insulation shielding performance is further improved, guaranteed the safe and reliable of use.
When this class electricity connector is used to add the electric cup of hot water, each elasticity electric contact point on the plug connects power supply, a metal derby is put in the socket upper surface, the electric cup body is promptly placed on it, between electric cup body and horizontal metal piece, have two shell fragments that independently are heated, be heated shell fragment below is two to thoroughly do away with the edge push rods, when this shell fragment that is heated generates heat under the situation of the dry combustion method of electric cup body, burning, be bent downwardly, and depress push rod, contacting of push rod and then disconnection elasticity electric contact point and power supply, thus outage prevents dry combustion method, burning.For example (publication number is disclosed Chinese invention patent on October 10th, 2007 " a kind of dry burning self-lock protection structure ": just announced a kind of self-lock protection structure that can prevent dry combustion method CN101051723A); it includes two shell fragments that are heated; place the push rod under the shell fragment that is heated; it is characterized in that: have groove in the middle of at least one described push rod; be provided with the fixing elastic wire of an end in push rod one side; described steel wire is held out against by a wedge-shaped catch and is affixed on the push rod surface; be heated at the shell fragment that is heated and be bent downwardly under the state that moves downward of compressing push rod; elastic wire snaps in the push rod groove, the locking push rod.But, production application through the later stage is found, recessing in the middle of push rod, snap in the structure of push rod intermediate groove by elastic wire, its elasticity is not fine, and, the diameter of general cylinder ejector rod is unlikely accomplished very big, it is very dark that groove in the middle of the push rod also can not leave, and elastic wire snaps in slippage easily behind the push rod groove, and security performance is good inadequately; And on manufacturing process, need offer groove in the middle of push rod, production technology is comparatively complicated, assembles up also more loaded down with trivial details.
The utility model content
Technical problem to be solved in the utility model is to provide heat-sensitive actuating structure in the high thermostat of a kind of novel reliability simple in structure at above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the heat-sensitive actuating structure in this thermostat, it is arranged on the plug body in the electric connector, and power is provided for the contact deciliter mechanism of control circuit break-make in the plug body, described heat-sensitive actuating structure comprises at least one flexure strip that is heated, it is characterized in that: this heat-sensitive actuating structure also comprises a metal substrate, have at least one and the opening that flexure strip matches that is heated on the metal substrate, the flexure strip that is heated accordingly is positioned at this opening and can moves up and down along this opening, and correspondingly, be movably set with the lever of an insulation in the described plug body, this lever is provided with a contact stud that places in the described opening, also be provided with on this lever one with plug body in the low link stopper that offsets of conductive contact film free end, the other end of conductive contact film is fixed in the plug body, and makes the contact stud of described lever have the trend that exposes to all the time outside the metal substrate; In addition, the external power supply binding post is set between conductive contact film and the lever, described conductive contact film contacts with described external power supply binding post under nature.
As improvement, the described flexure strip that is heated is one to have the circular temperature control sheet that central authorities discharge tongue.
Preferably, described conductive contact film and the contacted position of external power supply binding post are provided with first conductive contact, and described external power supply binding post and the contacted position of conductive contact film are provided with second conductive contact.
Compared with prior art, advantage of the present utility model is: the principle by lever realizes the contact deciliter of control circuit break-make in the plug body, and structure is simple more novel, the reliability height.
