Abstract
The utility model relates to a fuse for circuit protection, in particular to a thermal control fuse that can be repeatedly used, which comprises a shell, a button on the shell and a pressure contact spring connected with a dynamic contact bridge through the button. Wherein, a clearance is provided between the dynamic contact bridge and a static thimble socket. The dynamic contact bridge contacts the static thimble socket through the button. A locating spring leaf is positioned on the button. In addition, the locating spring leaf is also positioned on a gear at end of a rotating shaft. Melting point thermal control alloys are arranged between the rotating shaft and a temperature probe out of the shell. The rotating shaft is connected with a static contact pin. Moreover, a trip spring is arranged between the static contact pin and button. The utility model can be repeatedly utilized, thus saving cost and improving operating efficiency.
Description
Technical field
The utility model relates to a kind of fuse that is used for circuit protection, is specially a kind of repeatedly used temperature control fuse.
Background technology
Fuse generally is used for the overload protection of circuit, and in use after the fusing, the needs that have change fusible link or fusing plate, have in addition need whole fuse.The use of this fuse is the money that expends again consuming time, therefore, necessary design a kind of after fuse blows also repeatedly used fuse.
Summary of the invention
The purpose of this utility model is to provide a kind of temperature control fuse that can use repeatedly at the defective of existing fuse, both can save cost, can improve service efficiency again.
The technical solution of the utility model is as follows: repeatedly used temperature control fuse, comprise shell and the button that is located on the shell, button connects by contact pressure spring and movable contact bridging, leaves the gap between movable contact bridge and the quiet lug plate, by pressing button the movable contact bridge is contacted with quiet lug plate; Button is provided with Location resilient piece, and Location resilient piece is bearing on the gear of roller end, rotating shaft and be located between the outer temperature-sensitive head of shell and be provided with fusing point temperature control alloy, and rotating shaft is connected with quiet leg, is provided with the dropout spring between quiet leg and the button.
The utility model is installed in the circuit, and when equipment ambient temperature of living in was higher than the melting temperature of alloy between rotating shaft and the temperature-sensitive head, alloy melted, the gear of roller end loses supporting force, under the effect of dropout spring, movable contact bridge and quiet lug plate disengage, and circuit is disconnected.When temperature drops to the melting temperature that is lower than alloy between rotating shaft and the temperature-sensitive head, press the button, equipment can work on again.The utility model can use repeatedly, has both saved cost, has improved service efficiency again.

Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. quiet lug plate 2. movable contact bridges 3. quiet leg 4. rotating shafts 5. temperature-sensitive heads 6. buttons 7. contact pressure springs 8. shells 9. dropout springs 10. gears 11. Location resilient pieces
Embodiment
As shown in Figure 1, repeatedly used temperature control fuse comprises shell 8 and the button 6 that is located on the shell 8, button 6 is connected with movable contact bridge 2 by contact pressure spring 7, leaves the gap between movable contact bridge 2 and the quiet lug plate 1, by pressing button 6 movable contact bridge 2 is contacted with quiet lug plate 1; Button 6 is provided with Location resilient piece 11, Location resilient piece 11 is bearing on the gear 10 of rotating shaft 4 ends, rotating shaft 4 and be located between the outer temperature-sensitive head 5 of shell 8 and be provided with fusing point temperature control alloy, rotating shaft 4 is connected with quiet leg 3, is provided with dropout spring 9 between quiet leg 3 and the button 6.Select for use tin-mercury alloy as the fusing point temperature control alloy between rotating shaft 4 and the temperature-sensitive head 5 in the present embodiment.
The course of work of the present utility model is as follows:
(A) press the button 6, movable contact bridge 2 is connected with quiet lug plate 1, quiet leg 3, Location resilient piece card 11 is stuck on the gear 10 at this moment, and contact pressure spring 7 is in running order, can guarantee that the contact on the movable contact bridge 2 contacts well with the contact of quiet leg 3 with quiet lug plate 1, equipment is in running order.
(B) when electric current is excessive, the heat energy that is produced rotates by the gear 10 that Location resilient piece drives in the rotating shaft 4 because of the effect of dropout spring 9 greater than alloy melting point temperature between temperature-sensitive head 5 and the rotating shaft 4, and this equipment can automatic disconnection.
(C) be used for firing equipment when this equipment, equipment ambient temperature of living in is higher than the melting temperature of alloy between rotating shaft 4 and the temperature-sensitive head 5, and equipment also can automatic disconnection.
(D) after equipment disconnected, because of equipment does not have current path, when perhaps this equipment was used on the heater, heater also was failure to actuate because of outage, and temperature can descend again.When temperature is lower than the melting temperature of alloy between rotating shaft 4 and the temperature-sensitive head 5, press the button 6 equipment and can work on again.
This equipment can not only replace fuse in the market, and can use the temperature protection equipment that also can replace in the small household electrical appliance repeatedly.
