Abstract
The utility model discloses an energy-saving pull-switch capable of prolonging the lifetime of lamp whose ratchet wheel is composed of six-bladed wheels that connecting into integration and a circular wheel. The pull-switch is provided with an applique circuit which is composed of upper and lower conducting strips and a negative temperature coefficient thermistor inside. The electric current goes through the applique circuit first under the action of the ratchet wheel when switching on in order to prevent the filament from the impact of the over-current so as to prolong the life and save the energy. The utility model has the advantage of simple structure and is suitable for household as well as other situations.
Description
The utility model relates to the stay-supported switch of lighting.
Because the filament cold-state resistance of lighting bulb is far below its hot resistance, in the moment of turning on light, filament is subjected to the impact than the big 20-40 of rated current " overcurrent " doubly, and the filament that causes most of bulbs is blowing in a flash of turning on light.The energy loss that this " overcurrent " causes, it also is very important adding up.For avoiding the impact of this " overcurrent ", once developed the bulb device for prolonging of many types abroad, and patented.For example, (United States Patent (USP) No. 2675452, No. 4350931) of placing resistance or diode between lamp socket and lamp holder arranged, also there be resistance is installed in (No. the 2756382nd, United States Patent (USP)) in the switch (No. the 851799th, Russian Patent, No. the 2486753rd, the French Patent (FRP)) that adopts triode in addition or have the circuit arrangement of some elements to achieve the above object.Though all said apparatus can play the bulb effect, the complex structure that has, have will be in the whole process of bulb work consumed power, the effect of lengthening the life that has is unsatisfactory.
The purpose of this utility model is, designs a kind of simple structure, easy to use and stay-supported bulb switch with the power savings of well lengthening the life.
The utility model is that its development person further proposes on the basis of No. 85200535 patent of CN that he has obtained.It comprises and existing regular tap base, loam cake, cable quadrant, conducting strip, three-jaw conducting strip, lug plate mutually, and being provided with one especially by last conducting strip, down conducting strip, the adjunct circuit that places the negative temperature coefficient thermistor between the upper and lower conducting strip to form, the work of this adjunct circuit is by the action realization of a ratchet that is made of six ratchet wheels and garden wheel.
Below in conjunction with accompanying drawing the utility model is explained:
Fig. 1 has illustrated the operation principle of the utility model in opening process: the power end A of switch at first connects resistance terminal B(Fig. 1-2), bulb enters warming up period; And rear end A and C end join (Fig. 1-3), and bulb enters the operate as normal phase.Wherein resistance 5 is a negative tempperature coefficient thermistor.Filament is cold conditions before turning on light, resistance is little; Enter the initial time of warming up period at it, because to be the resistance of resistance 5 connected in series bigger with filament, entire circuit has big resistance, and electric current can only " steadily " pass through filament.Afterwards, filament heating and resistance increases, but the thermistor of this moment also generates heat because of the function of current is because its negative temperature coefficient feature and resistance reduces makes the total resistance in the circuit keep in a basic balance, thereby avoided the impact of " overcurrent ".Bulb inserts normal circuit again through behind the above-mentioned warming up period, enters normal operating conditions.The thermistor of this moment is in short-circuit condition and quits work.
Fig. 2 and Fig. 3 have pointed out practical structures of the present utility model.It comprises base (2), loam cake (11), cable quadrant (1), conducting strip (3), three-jaw conducting strip (7), lug plate (10), its technical characterictic is, the last conducting strip (4) that it also comprises and lug plate (10) joins, down conducting strip (6), place negative temperature coefficient thermistor (5), ratchet (8) between upper and lower conducting strip (4) and (6), insulation spacer (9) in addition between last conducting strip (4) and the following conducting strip (6).And by Fig. 2 and Fig. 5 as can be known, ratchet (8) is by fusing mutually and two concentric wheel bodys constitute: i.e. six ratchet wheels (81) and garden wheel (82).
Fig. 4 to Fig. 7 has pointed out the course of work of the present utility model.Fig. 4 is the off state of switch.During switch motion, ratchet (8) rotates along the direction of arrow among the figure, because the diameter of garden wheel (82) identical with the tooth root garden diameter of six ratchet wheels (81) (being the tooth top garden diameter of the diameter of garden wheel (82)) less than six ratchet wheels (81), following conducting strip (6) is at first connected (Fig. 6) with three-jaw conducting strip (7), electric current by three-jaw conducting strip (7) through down conducting strip (6), thermistor (5), go up lug plate (10) among conducting strip (4) and Fig. 3 contrary direction of this approach (or along) and enter bulb, make filament pre-heating; Then along with being rotated further of ratchet (8), last conducting strip (4) directly with three-jaw conducting strip (7) connection (Fig. 7), electric current directly enters bulb, makes it to enter normal operating conditions.Quit work because of upper and lower conducting strip (4), (6) all make resistance (5) be in short-circuit condition with three-jaw conducting strip (7) connection this moment.Used negative temperature coefficient thermistor (5) has that volume is little, instantaneous power is big, withstand voltage high characteristic, for ease of installing and using, it is designed to the button-type flakelet.
Experiment showed, adopt switch described in the utility model after because " overcurrent " of the moment of having avoided turning on light produces, more existing regular tap can prolong bulb life more than 3 times, saves energy 4% to 6% and do not influence the normal illumination of bulb.
The drawing explanation: in aforementioned figures, the meaning of each reference signs is:
1---cable quadrant
2---base
3---conducting strip
4---go up conducting strip
5---negative tempperature coefficient thermistor
6---following conducting strip
7---the three-jaw conducting strip
8---ratchet (wherein 81-six ratchet wheels, 82-garden wheel)
9---insulation cushion
10---lug plate
11---loam cake
Claims (2)
1, a kind of stay-supported switch that is used for lighting bulb, it comprises base, loam cake, cable quadrant, conducting strip, three-jaw conducting strip, lug plate, feature of the present utility model is, the last conducting strip that it also comprises and lug plate joins, down conducting strip, place negative temperature coefficient thermistor, ratchet between the upper and lower conducting strip, described ratchet partly is made of six ratchet wheels that fuse mutually and garden wheel two.
