Specific embodiment
The present invention is further elaborated by following example.
Referring to shown in Fig. 1~4, a kind of Kick type temperature controller of Anti-surging electric current, including bimetal disk 10, leading truck 4,
Terminal 6, leaf spring terminal 8, leaf spring 9, actuating strut 11, fixed contact 12, fishplate bar 13, moving contact 15, housing 16, shell 17 and cover board
18, moving contact 15 is riveted on 9 one end of leaf spring, and leaf spring 9 contacts with leaf spring terminal 8 and connected by the 2nd rivet 7 and the riveting of shell 17
It connects, fixed contact 12 is riveted on 13 one end of fishplate bar, and 13 the other end of fishplate bar is fixed on shell 17, and fixed contact 12 is located at moving contact 15
Within the scope of top and movement travel in the moving contact 15, terminal 6 passes through the 1st rivet 5 and 17 riveting of shell, shell 17
In housing 16, outer cover plate 18 passes through leaf spring terminal 8 and terminal 6 is set to 16 opening of housing, 18 periphery of outer cover plate and housing
The connection of 16 opening peripheral contacts, 18 liang of pins of outer cover plate and two socket plug connections in housing 16, in the bimetal disk
10 tops are successively arranged capping 3, locating rack 2 and power-type NTC thermistor 1 upwards, and leading truck 4 is set to the intermediate circular groove of shell 17
In 17-2, heating wire 14,14 both ends of heating wire are equipped in the 17 intermediate annular groove 17-1 of shell below bimetal disk 10
It is welded to connect respectively with fishplate bar 13 and terminal 6, the periphery of the bimetal disk 10 is connected to 3 lower surfaces of capping and is located at by sealing
Lid 3 and shell 17 are formed by space, and actuating strut 11 slides up and down with the central emptying aperture of leading truck 4 and connect, on actuating strut 11
End face and bimetal disk 10 connect, and 11 lower end surface of actuating strut is connect with the bump contacts of leaf spring 9, the power-type NTC
Thermistor 1 is placed in 2 cavity of locating rack, and 1 two pins of power-type NTC thermistor are welded with leaf spring terminal 8 and terminal 6 respectively
Connection.
The Kick type temperature controller circuit is formed in parallel by the 1st branch 20 and the 2nd branch 21.1st branch 20 is by fixed
The switch that contact 12 and moving contact 15 form is connected in series with heating wire 14.2nd branch 21 is by a power-type NTC temperature-sensitive
Resistance 1 is constituted.
After load booting, since fever, its surface temperature can reach 100-200 DEG C to power-type NTC thermistor 1 rapidly,
Bimetal disk 10 below power-type NTC thermistor 1 acts upwards after being heated, top and bimetallic on actuating strut 11
Disk 10 separates, and in leaf spring 9, moving contact 15 contacts no longer application active force with fixed contact 12.At this point, due to dynamic, fixed contact 15,
12 resistance of 20 resistance of the 1st branch formed with heating wire 14 much smaller than the 2nd branch 21 locating for power-type NTC thermistor 1, work
Make the 1st branch that electric current has largely passed through dynamic, fixed contact 15,12 and heating wire 14 forms, heating wire 14 is because flowing through electric current hair
Heat and maintain disk bimetallic 10 to be maintained at the state after movement upwards, thus, guarantee dynamic, fixed contact 15,12 and heating wire 14
1st branch 20 of composition is in energized state always in temperature controller course of normal operation.Power-type NTC thermistor 1 is because of stream
The electric current crossed successively decreases and calorific value and temperature decrease rapidly, then resistance value increases rapidly.The resistance value of power-type NTC thermistor 1 is got over
Greatly, 20 electric current of the 1st branch is smaller, and calorific value is smaller, so as to cool down rapidly in temperature controller course of normal operation, enables
Power-type NTC thermistor 1 is completely recovered to rapidly room temperature high-impedance state from high temperature low resistive state, and reaching can inhibit surge electric
The remarkable result that stream can be such that power-type NTC thermistor cools down rapidly again.After loading shutdown, heating wire 14 stops fever, double
10 surface temperature of metal disk reduces rapidly, and restores original downward state, and 11 upper end face contact of actuating strut, and application acts on
Power enables moving contact 15 separate with fixed contact 12 in leaf spring 9.When load booting next time, and recycled by the above process.Both prolong in this way
The service life of power-type NTC thermistor 1 has been grown, and has guaranteed that it has sufficient cooling time, load has been can be suitably used for and needs frequency
The application of numerous switch.
