Embodiment
Describe embodiment in detail by reference to the accompanying drawings.A kind of automobile-used electromagnetic power main switch, comprise electromagnetic component 1, metal shell 2, dynamic iron core 3, movable contact spring component 4 and fixed electrode 5, described electromagnetic component 1 is primarily of magnetic conductive board 6, coil holder 7 and the main coil 8 be arranged on coil holder 7 are formed with ancillary coil 9, wherein ancillary coil 9 is arranged at the outside of main coil 8, and on the closed-loop path of ancillary coil 9, be in series with thermistor 10, this thermistor 10 is fixed on by 906 insulating cements in the groove of bakelite 11, one end of described thermistor 10 is connected to the first binding post 12 with the leading-out terminal of the ancillary coil 9 of being drawn by coil entrance hole 15, the other end of thermistor 10 is connected to the second binding post 13 with the end of incoming cables of the main coil 8 of being drawn by coil entrance hole 15, the leading-out terminal of the ancillary coil 9 of being drawn by Wire Hole 16 and the leading-out terminal of main coil 8 are connected to the 3rd binding post 14, second binding post 13 is connected with external cabling sheet respectively with the 3rd binding post 14.
The utility model pours into 906 insulating cements and thermistor can be helped to dispel the heat on the one hand, when it disconnects after battery main switch works long hours, thermistor just can be made in the short time to be in conducting state; Can thermistor being fixed on the other hand, preventing thermistor because shaking some hidden danger that may cause.
The benefit that thermistor brings after applying in battery main switch:
1, energy consumption reduces.General single group coil battery main switch, power during its adhesive is with equally large when keeping, and the maintenance stage of battery main switch after adhesive puts in place, holding power needed for its coil does not need too large, so general single group coil battery main switch is wasted there being a large amount of electric energy because of coil heating, compare and added the battery main switch of thermistor, the unicoil power that main coil power ratio is general when designing is little, but battery main switch enough can be allowed to work reliably in the maintenance stage, so just can reduce energy consumption when battery main switch works long hours.
2, pick-up voltage is low.Take nominal voltage as the battery main switch of 24V be example, pick-up voltage≤the 16V of such battery main switch of regulation is had in QC/T413, through test, unicoil battery main switch general on market seldom can arrive standard, general all at 18-19V, even higher, used the twin coil battery main switch of thermistor due to its ancillary coil power higher, there is provided a larger power can to during battery main switch adhesive dynamic iron core, thus ensure that battery main switch also can normally work when voltage is lower.Experiment results proved, the pick-up voltage of this novel battery main switch can reach about 15V.
3, caloric value is little.The coil heating amount of a battery main switch is directly connected to its useful life.General nominal voltage is the electric current of battery main switch when normal work in coil of 24V is 0.5-0.6A, and that is, its coil power is 12-15W.Adopt the battery main switch of thermistor; utilize the overheat protector characteristic of thermistor; its adhesive put in place start working 2 seconds after just by the current limit by ancillary coil at about 0.08A; and the operating current of another group main coil only has 0.3A; that is; the coil total current of this battery main switch is 0.38A, and its coil power only has 9W.Like this, just effectively reduce the caloric value of coil, thus not only energy-conservation but also useful life of battery main switch can be extended.
4, consumptive material is few.On consumption enamelled wire, through disassembling the same model battery main switch of other producers, the enamelled wire consumption of their battery main switch is greatly about about 120g.And battery main switch of the present utility model, come by two groups of coils during adhesive, its main coil is only required to be iron core provides one to be enough to the reliable power kept, that is main coil does not need too large power, so the enamelled wire that main coil can select wire diameter slightly smaller, and the number of turn also can suitably reduce; And ancillary coil need not work long hours, can adopt and reduce its length to strengthen its instantaneous power, because there is the existence of thermistor, thus not worry that it has serious fever phenomenon.Through measuring, when reaching above-mentioned standard, its enamelled wire consumed only has 93g.
5, the every technical parameter of graphic analyses following (for nominal voltage 24V):
Embodiment above describes general principle of the present utility model, principal character and advantage; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the scope not departing from the utility model principle; the utility model also has various changes and modifications, and these changes and improvements all fall in the scope of the utility model protection.
