Compared with prior art, the beneficial effects of the utility model are: this thermal switch, convenient and practical, applied range, and highly sensitive, the response time is short, stable and reliable for performance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model partial structurtes schematic diagram;
In figure: 1 shell, 2 electrical switch module, 3 power supplys, 4 signal conditioning circuit plates, 5 sensor chips, 6 wires, 7 connector decks, 8 sensors.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of thermal switch, comprise shell 1, electrical switch module 2, power supply 3, signal conditioning circuit plate 4, sensor chip 5, wire 6, connector deck 7 and sensor 8, one end of described sensor 8 and signal conditioning circuit plate 4, electric switch module 2 is potted in shell 1 by fluid sealant, the other end stretches out shell 1, filling by fluid sealant, can isolate the ingredient of each switch of shell 1 inside, be conducive to the stable performance of switch, fluid sealant can also prevent high temperature on the impact of each element of switch, make switch not fragile, described wire 6 passes through epoxy encapsulation, one end of wire 6 and sensor chip 5 are by being welded and fixed, can prevent wire 6 from making wire aging because of high temperature or low temperature effect, the serviceable life of extension lead 6, wire 6 will because of temperature information sensor chip 5, one end of wire 6 is connected with connector deck 7, can whole device be fixed on the parts of required monitor temperature, be not easy to come off, and good stability, described sensor chip 5 and signal conditioning circuit plate 4 pass through connection, signal conditioning circuit plate 4 and electrical switch module 2 pass through connection, sensor 8 can monitor external temperature by the impact of temperature on resistance, after the temperature information of monitoring is processed by signal conditioning circuit plate 4 by sensor chip 5, send to electrical switch module 2, described signal conditioning circuit plate 4 is integrated with amplifying circuit, shaping circuit, comparator circuit and relay, signal conditioning circuit plate 4 is at the temperature information sent sensor chip 5, by amplifying, shaping, export low and high level and alarm relay signal more afterwards, thus drive electrical switch module 2, if temperature exceedes the temperature preset, circuit for alarming will give the alarm signal, and control circuit can cut off the circuit of external electrical equipment, it is outside that described power supply 3 is located at shell 1, power supply 3 provides electric power for whole device, heat insulator is equipped with outside shell 1 and power supply 3, reduce the impact of temperature on power supply 3 and other external electrical equipment, improve the serviceable life of this thermal switch, make its work more stable.This thermal switch, convenient and practical, applied range, highly sensitive, the response time is short, stable and reliable for performance, can also the real time data of monitor temperature at any time.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
