The high resistance branch power-off, the high resistance branch after power-off can not continue to the disconnection shape of the low resistance branch
State, the low resistance branch are connected again, are returned to original state.
Further, the high resistance branch main body uses PTC heater.
Further, the low resistance branch is equipped with fixed contact and moving contact, and the fixed contact is contacted with the moving contact
The then low resistance branch conducting, the fixed contact do not contact the then low resistance branch with the moving contact and disconnect.
Further, whether the fixed contact and the moving contact contact by the arc being located above the PTC heater
Bimetal leaf control, at a circuit, the PTC heater is persistently powered hair for the high resistance branch and entire circuit communication
Heat leads to the arc bi-metal plate deformed, and then struts the moving contact, disconnects the low resistance branch.
Further, the low resistance branch mainly by lug plate, the movable contact spring fixed with the lug plate, be fixed on institute
State moving contact, the fixed contact below the moving contact and the fixed touching plate group connecting with the fixed contact of movable contact spring end
At.
Further, including porcelain seat, the PTC heater are fixed on the porcelain seat, and the lug plate passes through long rivet
It is fixed on porcelain seat one end, the fixed touching plate is fixed on the porcelain seat other end by short rivet.
Further, the PTC heater bottom is equipped with metal clips；It is set between the PTC heater and the porcelain seat
There is metal locking plate.
The utility model also protects the temperature adjustment stick for using above-mentioned hand-reset temperature limiter.
The utility model has the beneficial effects that 1. when experiencing overtemperature, load can be disconnected automatically, and continue to keep load disconnected
It opens, there is no the problem of load is connected again；2. can restPose automatically after power-off, it is not necessarily to after-sales service, convenient for making
With.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of hand-reset temperature limiter.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.The utility model
Embodiment is given for the purpose of illustration and description, and be not be limited to exhaustively or by the utility model it is disclosed
Form.Many modifications and variations are obvious for the ordinary skill in the art.Selection and description are implemented
Example be in order to more preferably illustrate the principles of the present invention and practical application, and make those skilled in the art it will be appreciated that
The utility model is to design various embodiments suitable for specific applications with various modifications.
Embodiment 1
The utility model protects a kind of hand-reset temperature limiter, including two branches in parallel, respectively low resistance branch
With high resistance branch；When proper device operation, the low resistance branch is connected and with entire circuit communication at a circuit, is born
It carries and is in energized state；When temperature control goes wrong, and load temperature is more than certain numerical value, the low resistance branch is disconnected, described
High resistance branch and entire circuit communication maintain the off-state of the low resistance branch at a circuit；After power supply disconnects,
The high resistance branch power-off, the high resistance branch after power-off can not continue to the disconnection shape of the low resistance branch
State, the low resistance branch are connected again, are returned to original state.
In the present embodiment, as shown in Figure 1, what the low resistance branch was mainly fixed by lug plate 1, with the lug plate
Movable contact spring 2, the moving contact 3 for being fixed on the movable contact spring end, the fixed contact 4 below the moving contact and touching is determined with described
The fixed touching plate 5 of head connection forms.
Hand-reset temperature limiter is equipped with porcelain seat 12, is fixed on PTC heater 8 on the porcelain seat, the lug plate 1 passes through length
Rivet 11 is fixed on porcelain seat one end, and the fixed touching plate 5 is fixed on the porcelain seat other end, the PTC by short rivet 10
Heater bottom is equipped with metal clips 9；Metal locking plate 7 is equipped between the PTC heater and the porcelain seat.Lug plate 1, long riveting
Nail 11, metal locking plate 7, PTC heater 8, metal clips 9, short rivet 10, fixed touching plate 5 constitute high resistance branch.The dynamic touching
Arc bimetal leaf 6 is equipped between piece and the PTC heater.
Working principle (only by taking temperature adjustment stick as an example):
1. temperature adjustment stick works normally, electric current passes through lug plate, movable contact spring, moving contact, fixed contact, fixed touching plate and entire electricity
Road connection is at a circuit, the heater load display energized state of temperature adjustment stick connection at this time, heater persistent fever.
2. when the adjustable temperature controller failure (constantly on) on temperature adjustment stick cannot manage the temperature of load heater, fever
Know from experience persistent fever, when temperature limiter reaches specific temperature, bimetal leaf on temperature limiter is heated reversal deformation, struts dynamic touching
Piece separates moving contact and fixed contact, causes entire circuit to disconnect load heater and stops fever.
3. lug plate, long rivet, metal locking plate, PTC heater, metal clips, short rivet, fixed touching plate and entire electricity at this time
Road forming circuit.PTC heater is high resistance heating part, after energization can persistent fever, the heat generated can allow bimetallic
Piece is constantly in heating status, to keep deforming, allows, fixed contact is always maintained at the state of disconnection, and then ensure that load
Heater will not generate heat again.
4. PTC heater power-off, PTC heater no longer generates heat, at this time bimetal leaf environment when extracting power-line plug
Constant temperature reduce, as low as to a certain degree when, bimetal leaf restore original form, at this time move, fixed contact contact, entire circuit return
Multiple original state, the line plug that plugs in again can work normally.
Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, this field and those of ordinary skill in the related art are not making creative work
Under the premise of every other embodiment obtained, all should belong to the utility model protection range.
