In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with figure and instantiation, this utility model is further elaborated.
Embodiment 1
Refer to the temperature device for fusing shown in Fig. 1 to Fig. 2.It includes two electrodes, is provided with thermal fuse-link 2 between two electrodes, and the end of thermal fuse-link 2 is provided with electric conductor 3, and electric conductor is connected with the outer rim of battery-end electrode 1, and two electrodes pass through electric conductor and the thermal fuse-link formation electrical connection of being located between two electrodes.Herein, what electric conductor 3 adopted is little copper pearl.As can be seen from Figure 1, under normal operating temperature, the thermal cutoff device described in the present embodiment can guarantee that normal circuit operation to total；And when circuit temperature increases to over nominal threshold value, the temperature of circuit makes the electrode contact surface temperature of thermal fuse-link described in the utility model raise, thermal fuse-link near electrode undergoes phase transition after reaching softening temperature (i.e. nominal threshold value), thermal fuse-link softens, the support force of the thermal fuse-link of softening is not enough to support its interior electric conductor, electric conductor in thermal fuse-link from original position landing, finally owing to the effect electric conductor of gravity falls from the outer rim of electrode, thermal fuse-link fuses, the electrical connection collectively formed by thermal fuse-link and electric conductor in original circuit is also just disconnected, circuit quits work immediately.Thermal cutoff device described in the present embodiment is the effect due to gravity so that the electric conductor in the thermal fuse-link of softening caves in and falls and disconnect electrical connection.Due to the drive of gravity Yu electric conductor, thermal fuse-link exceedes in softening occurs nominal threshold value will disconnect rapidly in temperature.Namely the fusing of temperature device for fusing is directly controlled by the temperature of circuit.Such design makes circuit will not work long hours at unsafe temperature that comparison is high.
Electric conductor 3 good conductivity, fusing point is higher than external heat fuse-link.What external heat fuse-link 2 adopted is low temperature scolding tin, and fusing point is between 140 ~ 150 DEG C, and material is softer.Thermal fuse-link itself can conduct electricity, and thermal fuse-link ensure that at normal working temperature and can turn between two electrodes.When its connection temperature of powered cell close to softening temperature time, thermal fuse-link 2 undergoes phase transition, and has mobility.And electric conductor 3 maintains the original state at such a temperature.Under the situation that thermal fuse-link 2 Heated Flow increases, electric conductor about 3 discontinuity equalization, the support force of the thermal fuse-link of softening is not enough to support its interior electric conductor, as shown in Figure 2 electric conductor 3 in the thermal fuse-link 2 of softening along the outside landing of battery-end electrode 1, when the surface tension of the thermal fuse-link of outside softening cannot support the electric conductor 3 of inside again, electric conductor 3 caves in, the rolling inertia of electric conductor 3 and acceleration of gravity make the column structure moment of thermal fuse-link disconnect, and form the state shown on the right side of Fig. 2.Compared to common current fusing electric fuse, owing to need not lead to excess current control fusing, the speed of described New temperature device for fusing fusing is faster, and more sensitive to temperature.

Embodiment 2
With reference to Fig. 3 and Fig. 4.Internal end electric conductor 3 and middle part electric conductor 32, electrode 1 and the electrode 4 of being provided with of thermal fuse-link 2 electrically connects with thermal fuse-link 2 formation herein.Herein, what external heat fuse-link 2 adopted is low temperature scolding tin, and fusing point is between 140 ~ 150 DEG C；End electric conductor 3 and middle part electric conductor 32 can be little copper balls, and small copper block etc. is variously-shaped.Total is from figure 3, it can be seen that electric conductor in the thermal fuse-link state that is at this moment in a kind of instability, easily caves in.Electric conductor good conductivity, fusing point is higher than external heat fuse-link.External heat fuse-link material is softer, and when the temperature of powered cell contacted is close to softening temperature, electrode contact surface temperature raises, and the thermal fuse-link 2 near electrode undergoes phase transition after reaching softening temperature (i.e. nominal threshold value), and softening has mobility.And end electric conductor 3 and middle part electric conductor 32 maintain the original state at such a temperature.Under the situation that thermal fuse-link 2 Heated Flow increases, electric conductor is due to action of gravity, similar to Figure 4, to different directions landing.When temperature device for fusing cannot be supported the electric conductor of inside by the surface tension of the thermal fuse-link of thermal softening again, middle part electric conductor 32 caves in, rolling inertia and the acceleration of gravity of middle part electric conductor 32 make thermal fuse-link structure moment disconnect, original electrical connection has not just existed yet, battery cannot normal power supply, circuit also just quits work rapidly.The principle that temperature device for fusing adopts with embodiment 1 is identical, is all utilize action of gravity in electric conductor so that the electric conductor in thermal fuse-link caves in and falls and disconnect electrical connection.Due to the effect of electric conductor, thermal fuse-link exceedes in softening occurs nominal threshold value will disconnect rapidly in temperature.Such design makes circuit will not work long hours at unsafe temperature that comparison is high.
The present embodiment and embodiment 1 are distinctive in that position and the annexation of electric conductor.In the present embodiment, it is connected in the way of point cantact between adjacent two electric conductors.The electric conductor of top is exactly the point that both contact with the edge of the view field of underlying conductive contact level.Owing to being point cantact, the state that at this moment electric conductor in thermal fuse-link is in a kind of instability, easily caves in, easily falls.At this moment electric conductor easily when outside thermal fuse-link heats up softening landing stagger, losing the support of thermal fuse-link, thus falling, disconnecting two interelectrode electrical connections.
Owing to electric conductor is without influence on interelectrode electrical connection, therefore, it is located at the electric conductor in thermal fuse-link without influence on the normal operation of circuit under normal temperature, thus, the quantity of electric conductor is unrestricted.Contrary, owing to electric conductor adds, when battery temperature is higher than nominal threshold value, the electric conductor of increase can make the thermal fuse-link of softening cave in rapidly to fall, disconnect the electrical connection between electrode equally.
When described in the present embodiment, the electric conductor within thermal fuse-link can fall when battery temperature exceedes nominal threshold value in by the thermal fuse-link of thermal softening, caves in.Thus the present embodiment is not necessarily intended to the outer rim that thermal fuse-link is arranged on electrode.In this case, even if with the electric conductor of electrode contact just in electrode plane, the electric conductor within thermal fuse-link can also make the thermal fuse-link of softening cave in rapidly, disconnects the electrical connection between electrode.
Embodiment 3
With reference to Fig. 5, two electrodes of temperature device for fusing are provided with thermal fuse-link 2, and thermal fuse-link 2 connects the end of battery-end electrode and is provided with some electric conductors in irregular shape 3.Between two electrodes, the electric conductor by being located between two electrodes forms electrical connection, and electric conductor is connected with the outer rim of battery-end electrode 1.Thermal fuse-link outside electric conductor acts the effect supporting connection when not reaching to set threshold values only in temperature, therefore can only use a small amount of hot fusible material.Hot fusible material also not necessarily must by fully wrapped around for electric conductor live.
Owing to electric conductor is without influence on interelectrode electrical connection, it is located at the electric conductor of thermal fuse-link end without influence on the normal operation of circuit under normal temperature, thus, the shape of electric conductor and quantity are all unrestricted.Contrary, owing to electric conductor adds, when battery temperature is higher than nominal threshold value, the electric conductor of increase can make thermal fuse-link fall cave in rapider, thus the electrical connection disconnected faster between electrode.
Embodiment 3
With reference to Fig. 6, it is also possible to increase middle part electric conductor 32 in thermal fuse-link, as long as formation path can be connected between electrodes.Electric conductor within thermal fuse-link can cave in when battery temperature exceedes nominal threshold value in by the thermal fuse-link of thermal softening, thus is not necessarily intended to the outer rim that thermal fuse-link is arranged on electrode.In this case, even if with the electric conductor of electrode contact just in electrode plane (situation of similar embodiment 2), the electric conductor within thermal fuse-link can also make the thermal fuse-link around softened cave in rapidly, fall, the electrical connection between electrode is disconnected.And this example demonstrates that, thermal fuse-link connects this situation of outer rim of circuit end electrode and battery-end electrode 1 at a slant and still can select that and set up middle part electric conductor 32 in thermal fuse-link.The structure that this instability is easily caved in can realize the function that temperature device for fusing high temperature fuses rapidly.It is to say, temperature device for fusing also not necessarily must keep state vertical in Fig. 3 when mounted.On the contrary, the state such as the inclination of Fig. 6 is more conducive to caving in of polyhedron electric conductor.Temperature device for fusing is also not limited to protection battery, and can be applied in each quasi-instrument needing that temperature is strictly controlled.
