Abstract
The utility model discloses a heat protector, which comprises an insulating bottom base which is provided with two static copper feet. The utility model is characterized in that one end of each static copper foot in the insulating bottom base is riveted with a silver contact point. A silver-copper pressing plate contacted with the silver contact points of the two static copper feet and a small spring are sheathed on a pushing rod made of PPS rigid material. The outer surface of one end of the insulating bottom base is provided with a circular bimetal plate sealed by an aluminum shell. One end of the pushing rod is in contact with the circular bimetal plate and the other end of the pushing rod passes through a bottom base cover to be in contact with a pin tumbler. The insulating bottom base is arranged on an outer shell and one end of the outer shell is provided with a pressing button connected with a pin tumbler basket. A big spring is arranged between the pressing button and the pin tumbler basket. The inner part of the pin tumbler basket also contains one pin tumbler by a pin tumbler containing plate. The bimetal plate of the utility model is sealed in an insulating environment and is insulated from a conductive part. Thus, the utility model has the advantages of safety, long service life, etc. The utility model is suitable for the work in an outdoor bad environment and is particularly suitable for the use of a wire disc of a power supply connector.
Description
Technical field
The utility model relates to a kind of thermal protector, particularly a kind of thermal protector that is installed in the drum.
Background technology
At present domestic normal employing thermal relay protection electrical equipment because its volume is bigger, can only be contained in the circuit of electrical equipment outside, is not the heating of directly experiencing electrical equipment inside, just reflects indirectly by electric current.Therefore, a kind of thermal protector that can be contained in electrical equipment inside need be arranged.The patent No. is that the Chinese patent " double-metal sheet type thermal protector " of CN91227524 discloses a kind of double-metal sheet type thermal protector; the base plate of packing in its shell; base plate one end is fixed a flexible member; silver point is fixed in the hole of flexible member, and the fixed contact sheet is contained in the flexible member below, its terminal lead that connects; base plate also connects a lead; the moulding bimetallic element is contained in two little ears of flexible member, and there is the arcuation projection at the flexible member middle part, and the insulation supporter is contained between shell and the fixed contact sheet.This installs buried at motor, electrical equipment inside.Its weak point is, protector because of between its shell and lower clamping piece, the bimetal leaf from nearer, in case deformed element just is easy to generate leaky.Particularly under outdoor adverse circumstances, situation is just more serious.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, cost is lower, safe and reliable, long service life, be adapted at the safety-type thermal protector of working under the outdoor adverse circumstances.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of thermal protector; comprise insulator foot; two quiet copper pin are arranged on insulator foot; it is characterized in that riveted joint has silver contact on the end of described quiet copper pin in insulator foot; one silver-bearing copper dynamic pressure sheet that can contact with the silver contact of two quiet copper pin and little spring are socketed on the top rod of the firm material of PPS; the circular bimetal leaf that the aluminum hull encapsulation is arranged in the outside of described insulator foot one end; one end of described top rod contacts with circular bimetal leaf; the other end of described top rod passes base cover and contacts with pellet shot from a slingshot; described insulator foot is installed on the shell; one end of shell has a button; button is connected with the pellet shot from a slingshot basket; between button and the pellet shot from a slingshot basket big spring is arranged, contain sheet by pellet shot from a slingshot in the pellet shot from a slingshot basket pellet shot from a slingshot is housed.
Because the utility model has been taked above-mentioned technical measures, it compared with prior art bimetal leaf be encapsulated in one the insulation environment in, isolated with current-carrying part, advantage such as therefore have safe and reliable, long service life, be adapted at working under the outdoor adverse circumstances, and also have characteristics such as simple in structure, that cost is lower, be active in one's movements, be particularly suitable for the power connector drum and use.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to accompanying drawing, the utility model comprises insulator foot 2, and two quiet copper pin 4 are arranged on insulator foot 2.Quiet copper pin 4 end outside connects lead, and riveted joint has silver contact 13 on the end of quiet copper pin 4 in insulator foot 2, and is this simple and practical.One silver-bearing copper dynamic pressure sheet 3 that can contact with the silver contact 13 of two quiet copper pin 4 and little spring 12 are socketed on the top rod 15 of the firm material of PPS, are enclosed in the insulator foot 2 by base cover 5.There is a circular bimetal leaf 1 to be encapsulated in the outside of insulator foot 2 one ends by aluminum hull 14.One end of described top rod 15 contacts with circular bimetal leaf 1, and the other end of top rod 15 passes base cover 5 and contacts with pellet shot from a slingshot 10.Described insulator foot 2 is installed on the plastic casing 7, and an end of shell 7 has a button 8, and button 8 is connected with pellet shot from a slingshot basket 6, and a big spring 9 is arranged between button 8 and the pellet shot from a slingshot basket 6.Contain sheet 11 by pellet shot from a slingshot in the pellet shot from a slingshot basket 6 pellet shot from a slingshot 10 is housed.
During normal the use, silver-bearing copper dynamic pressure sheet 3 is communicated with two quiet copper pin 4, makes current lead-through.When environment temperature is higher than setting, for example 56 ℃ the time, circular bimetal leaf 1 distortion pushes rod 15 pressure that overcome little spring 12 silver-bearing copper dynamic pressure sheet 3 and quiet copper pin 4 is disengaged, thereby cuts off the electricity supply, and plays a protective role.At this moment, protector can not automatically reset in-25 ℃.Want hand-reset, press button 8,, silver-bearing copper dynamic pressure sheet 3 is contacted with two quiet copper pin 4 again, make the multiple conducting of electric current by pellet shot from a slingshot basket 6, pellet shot from a slingshot 10, top rod 15.
