Abstract

The utility model relates to an electronic flashing lamp used for controlling the steering indication lamps of motor vehicles, which mainly comprises a miniature relay which is arranged in the casing body, a triode, a resistor and a capacitor. The conduction and the cutoff of the triode are adopted to control the miniature relay to attract and release, the on and off of the normally opened contact of the relay controls the lighting and quenching of the steering indication lamp, and then the flash of the steering indication lamp is controlled. The utility model has the advantages that the circuit structure is very simple, and the component only has four pieces; thus, the volume is relatively small, and the cost is relatively lowered; simultaneously the reliability is relatively increased, and convenience is brought to the installation.

Description

Electronic flasher

The utility model relates to a kind of electronic flasher that is used for controlling machine motor-car turning indicator.

The existing electronic flasher that is used for the motor turning indication, general electronic component is more, causes complex structure, volume to increase the also corresponding increase of cost.Though the electronic component that also has less (as the employed electronic flasher of liberation CA141 car), use therein high capacity chemical capacitor (about 2000 μ F) makes the also corresponding increase with cost of volume of this Der Blink und Abblendschalter.Because the volume conference is made troubles to installation.

In view of the foregoing, the purpose of this utility model provides a kind of simple in structure and volume is little, cost is low electronic flasher.

The purpose of this utility model is to realize like this; It comprises miniature relay, aerotron, resistance and the electric capacity that places in the housing, the coil two ends of miniature relay link to each other with the emitter of positive source and aerotron respectively, the base stage of aerotron links to each other with the common port of resistance and electric capacity, the other end of electric capacity links to each other with power cathode with the collecting electrode of aerotron, and the other end of resistance links to each other with positive source as the open contact of output control terminal through miniature relay.During use, its output control terminal links to each other with the motor turning indicator lamp, conducting that utilizes aerotron and adhesive and release by the control miniature relay, and, reach the purpose of control turning indicator flash of light with this by the light on and off of the switching control turning indicator of miniature relay open contact.

The utility model has the advantages that: circuit structure is extremely simple, and components and parts only have four, thereby volume is less relatively, the also corresponding reduction of cost, and the also corresponding raising of reliability brings great convenience to installation simultaneously.

Below in conjunction with accompanying drawing the utility model is explained.

Fig. 1 is a shape assumption diagram of the present utility model.

Fig. 2 is the utility model schematic circuit diagram.

By accompanying drawing as can be known, mainly (JZC-22F), aerotron BG, resistance R, capacitor C (50 μ F) constitute the utility model by miniature relay JZ, wherein miniature relay JZ and aerotron BG, resistance R, capacitor C place on the wiring board 6 in the housing 1, and housing 1 is provided with fixedly plug-in card 2 used when installing and the positive and negative electrode insert-connecting plate 3,4 that can link to each other with the power sources of motor vehicle both positive and negative polarity, exports insert-connecting plate 5.During installation, output insert-connecting plate 5 links to each other with the power end of turning indicator D, when circuit energized moment, the eb of electric current by miniature relay JZ coil and the aerotron BG capacitor C charging of becoming a partner, aerotron BG conducting this moment, relay J Z adhesive, its open contact is connected, electric current charges to capacitor C through resistance R, and turning indicator D is luminous, along with the capacitor C both end voltage raises, aerotron BG ends, relay J Z discharges, and promptly its open contact disconnects, and turning indicator extinguishes.The resistance R value is selected less, make the velocity of discharge of capacitor C by resistance R, turning indicator D greater than the become a partner charging rate of capacitor C of the eb of aerotron BG, when the capacitor C both end voltage drops to certain value, aerotron BG conducting, the adhesive of relay J Z open contact, repeat above-mentioned working process afterwards, realize the flash of light of turning indicator D with this.

Claims

1, a kind of electronic flasher that is used for controlling machine motor-car turning indicator, it is characterized in that: it comprises miniature relay, aerotron, resistance and the electric capacity that places in the housing, the coil two ends of miniature relay link to each other with the emitter of positive source and aerotron respectively, the base stage of aerotron links to each other with the common port of resistance and electric capacity, the other end of electric capacity links to each other with power cathode with the collecting electrode of aerotron, and the other end of resistance links to each other with positive source as the open contact of output control terminal through miniature relay.
