Abstract
The utility model relates to a self protective temperature current protector which comprises a case, an insulated isolation bracket, a movable contact chip, a static contact chip, a conducting wire, a press plate, a bimetallic strip and a heating body, wherein the insulated isolation bracket is arranged in the case; the movable contact chip and the static contact chip are arranged on the insulated isolation bracket; the conducting wire is led out of the case, and is connected with the movable contact chip and the static contact chip; a port of one end of the conducting wire is sealed and fixed; a platform extends from the insulated isolation bracket; the press plate, the movable contact chip and the bimetallic strip are orderly overlapped on the platform, and are tightly pressed; the free end of the bimetallic strip falls down; a slot provided with the heating body is formed on the insulated isolation bracket or the platform; and the heating body is arranged between the bimetallic strip and the static contact chip in a tight contact mode. The self protective temperature current protector is connected in series in a circuit of a protected electric appliance. When the protected electric appliance is in an overheat or overcurrent state, the bimetallic strip trips, contact points are off, the current of the protected electric appliance is cut off, and the heating body heats at the time, so the movable contact chip and the static contact chip always maintain an off state. Only when a power supply is completely switched off, the heating body can be cooled, so the bimetallic strip resets, and the movable contact point and the static contact point can contact. The safety of the protected electric appliance is improved.
Description
Technical field
The utility model relates to a kind of self-insurance's temperature current protector.
Background technology
Original temperature current protector is connected in the circuit of protected electrical equipment, and electric current is exported by lead through lead, movable contact spring, contact, static contact again.When ambient temperature reaches the specified take-off temperature value of bimetal leaf or the electric current by protector is delivered on the bimetal leaf spring leaf heating; when making the bimetal leaf temperature rise to specified take-off temperature value; the bimetal leaf take-off; flick reed; cut off electric current; shielded electrical equipment is no longer worked, avoid continue heating up and damaging, play the purpose of protection electrical equipment.When the protector ambient temperature dropped to specified reset temperature, bimetal leaf resetted, reed contact static contact, and automatic energized, protected electrical equipment is started working again.
Original temperature current protector comprises housing, is provided with insulation in the housing and supports, and the bimetal leaf of protector, static contact, movable contact spring and compressing tablet all place on the support, and dynamic and static contact disconnects the back along with temperature reduction meeting resets very soon.
The utility model content
The problem that the utility model need solve is exactly to overcome the original temperature current protector to have the defective that resets very soon after the disconnection, and a kind of self-insurance's temperature current protector is provided.The technical scheme that adopts is:
A kind of self-insurance's temperature current protector; comprise housing; be arranged on the active and static contact in the housing; the insulation isolation mount and draw the housing outer end and movable contact spring; the lead that static contact connects; housing is drawn the port insulating material sealing of lead one end; static contact is plugged on the described insulation isolation mount; stretch out a platform on the insulation isolation mount; pressing plate; movable contact spring and bimetal leaf are superimposed upon successively on the insulation isolation mount platform and compress; the free end freedom of bimetal leaf is sagging; offer groove on insulation isolation mount or the platform, described heater is arranged in the described groove with between bimetal leaf and the static contact and closely contacts.
Described platform is provided with the positioner to bimetal leaf and movable contact spring.
Be provided with location hole on described bimetal leaf and movable contact spring, be provided with protruding cylinder on platform, bimetal leaf and movable contact spring are enclosed within on the protruding cylinder.
Described platform one end has the downward gradient, and above-mentioned bimetal leaf is sagging along this gradient freedom.
The beneficial effects of the utility model are: the utility model is by being provided with a heater between static contact and bimetal leaf, when the electrical equipment energized is worked, run into overheated or bimetal leaf take-off during overcurrent, cut off electric current, the contact disconnects, at this moment, because heater is mounted between the active and static contact, heater begins heating, makes to keep off-state between the active and static contact always, has only when pulling out attaching plug, all behind the deenergization, along with temperature descends, bimetal leaf resets, and just can touch together between the active and static contact.Like this, avoided that electrical appliance automatically resets, electrical appliance causes danger having to work under the failure condition, improved the fail safe of electrical appliance.

Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See figures.1.and.2; the utility model self-insurance temperature current protector; comprise housing 6; be arranged on pressing plate 7, movable contact spring 5 (there is moving contact 2 end), bimetal leaf 4, static contact 3 (there is fixed contact 1 end), heater 8, insulation isolation mount 9 and the lead 11 that is connected with movable contact spring 5, static contact 3 of drawing in the housing 6 in housing 6 outer ends; housing 6 is drawn the port of lead 11 1 ends with 10 sealing of insulation fixed sealing material, plugs static contact 3 on the insulation isolation mount 9.Pressing plate 7, movable contact spring 5 and bimetal leaf 4 are superimposed upon successively on the platform 12 and compress, one end of platform 12 has the gradient, the free end of bimetal leaf 4 is sagging along this gradient freedom, offer groove on insulation isolation mount 9 between bimetal leaf 4 and the static contact 3 or the platform 12 heater 8 is installed, a convex column 13 is set on the platform 12 bimetal leaf 4, movable contact spring 5, pressing plate 7 are installed, bimetal leaf 4, movable contact spring 5 and pressing plate 7 are provided with in the housing 6 of packing into after borehole jack makes it to be fixed and clamped on protruding cylinder 13, and heater 8 closely contacts between bimetal leaf 4 and static contact 3.
The utility model is by being provided with a heater 8 between static contact 3 and bimetal leaf 4, this product is serially connected in the protected appliance circuit, energized when work, when running into overheated or bimetal leaf 4 take-offs during overcurrent, cut off electric current, and the contact disconnects.At this moment, because heater 8 is mounted between static contact 3 and the bimetal leaf 4, heater 8 begins heating, makes to keep off-state between the active and static contact always.Have only when pulling out attaching plug, after all cutting off the electricity supply, along with temperature descends, bimetal leaf 4 resets, and just can touch together between the active and static contact.Like this, avoided, protected electrical equipment is caused danger having to work under the failure condition, improved the fail safe of electrical appliance because of the automatically reseting of bimetal leaf.
Perhaps also a location notch can be set on platform 12, bimetal leaf 4 and movable contact spring 5 fixed card be located in the location notch also can locate.
Above-mentioned platform 12 can not have the gradient yet, as long as guaranteeing that bimetal leaf 4 one ends stretch out platform 12 outsides can be free sagging.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
