Abstract

The utility model relates to a protector for a heat fusing body, which comprises a contact leading wire, a sealing piece, an insulating porcelain bead, a casing and a leading wire. The utility model is characterized in that a temperature sensing agent, a drum-shaped spring, a compression spring and a movable contact are arranged in the casing, wherein the movable contact is arranged among an upper shim, a contact sheet and the contact leading wire, the compression spring is sheathed outside the movable contact and is clamped between the insulating porcelain bead and the upper shim, the drum-shaped spring is arranged between the upper shim and a lower shim, and the temperature sensing agent is arranged between the lower shim and the bottom of the casing. The utility model has the advantages of reasonable structure, small size and reliable operation, can perform a back-replenished heat protection action for electric heaters or other high-current device and can cut off a circuit to protect electric appliances against overheat damage under the condition of the failure of a temperature controller or other overwarm and overheat conditions.

Description

The thermal fuse-link protector
Technical field
The utility model relates to a kind of protector, particularly a kind of thermal fuse-link protector.
Background technology
All be provided with thermostat in existing electric heater or other high-current equipment, if but the thermostat inefficacy will produce the excess temperature superheating phenomenon, and make circuit be subjected to pyrolytic damage.The heat protective device that does not also have at present to mend after one guarantees that electrical appliance was not subjected to pyrolytic damage.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, reliable in action, the thermal fuse-link protector of concurrent heating protective effect after can playing high-current equipment.
The purpose of this utility model can reach by following measure: a kind of thermal fuse-link protector; comprise contact lead, sealed piece, insulation porcelain bead, shell, lead-in wire; it is characterized in that: be provided with temperature sensing agent, barrel-shaped spring, compression spring, moving contact in the enclosure; moving contact is located between Upper gasket, contact and the contact lead; its outer compression spring that is with; the compression Spring Card is located between insulation porcelain bead and the Upper gasket; barrel-shaped spring is located between Upper gasket and the lower gasket, and temperature sensing agent is located between lower gasket and the outer casing bottom.
The purpose of this utility model can also reach by following measure: lead-in wire communicates with moving contact by shell, contact.Upper gasket is located at the contact below, fits each other.The temperature sensing agent normality is a solid shape.
The utility model has following advantage compared to existing technology: rational in infrastructure; volume is small and exquisite, and reliable in action can play back concurrent heating protective effect to electric heater or other high-current equipment; under thermostat inefficacy or other excess temperature overheat condition, can cut off circuit and protect electrical appliance not to be subjected to pyrolytic damage.
Description of drawings
Fig. 1 is the preceding internal structure schematic diagram of the utility model action;
Fig. 2 is the internal structure schematic diagram after the utility model action.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model comprises contact lead 1, sealed piece (glue) 2, insulation porcelain bead 3, shell 4, lead-in wire 5, temperature sensing agent 6, barrel-shaped spring 7, compression spring 8, moving contact 9, pad 10, lower gasket 11, contact 12 etc.Contact lead 1 is drawn from the top of shell 4, and by sealed piece (glue) 2 and insulation porcelain bead 3 location; Moving contact 9 is located between shell interior the insulation porcelain bead 3 and contact 12, and can contact (or separation) with the contact 1-1 of contact lead 1; Compression spring 8 is placed on the moving contact 9, and is arranged between insulation porcelain bead 3 and the contact 12; Upper gasket 10 is located at contact 12 belows, fits each other; Barrel-shaped spring 7 is located between Upper gasket 10 and the lower gasket 11; Temperature sensing agent 6 normalities are solid-state, are located between lower gasket 11 and shell 4 bottoms, and lead-in wire 5 and shell 4 bottom connections, and communicate with moving contact 9 by shell 4, contact 12.Temperature sensing agent 6 can adopt materials such as benzene potassium acid (can adopt different materials according to different fusing points).
Before action, temperature sensing agent 6 is solid-state, and spring 8 is compressed, and moving contact 9 contacts with the contact 1-1 of contact lead 1 under the effect of barrel-shaped spring 7, makes circuit connect (see figure 1).Right in the normal operation of electrical equipment, temperature sensing agent 6 keeps solid-state.If ambient temperature reaches the fusing point of temperature sensing agent 6, temperature sensing agent 6 fusings, volume-diminished, compression spring 8 unclamps, and moving contact 9 and contact lead 1 is disconnected, thereby cut off the circuit (see figure 2).Temperature sensing agent 6 is in case distortion just can't be restored, and institute thinks one-time action.Right at the hot melt that more renews, must be repaired the circuit of mistake, and should be changed the temperature sensing agent 6 (thermal fuse-link) of same model, specification when changing in principle.
This protector one-time action cuts off electric current and has high-current circuit cut-out ability; it can bear the maximum current voltage (or current/voltage of 120V/25A) of 250V/16A; because resistance value own is low; element self heat effect also can not cause the drift of working point temperature, so move safe and reliable.
