Description

Electron flashing relay

The utility model relates to a kind of motor turning electronic lamp flasher.

At present both at home and abroad electronic flasher damages the fault that requires obviously difference the glisten detection of these two kinds of situations and the structure that series resistor silk in major loop is all adopted in discriminating to normal flash of light with because of certain lamp, just remove to control related circuit by the resistor wire sampling voltage and change its flash rate, its weak point is that resistor wire has big power consumption, the device temperature rise is unsuitable for working long hours and can causes the damage of Der Blink und Abblendschalter as overtime work; Disclose a kind of multifunctional vehicle electronic flash control device in CN2078252U, it selects for use time base circuit 555 to vibrate relay J ₁Do output control, J ₂Make Fault Control, aerotron BG is by resistor wire R ₀Detect the steering indicating light electric current identifying faulty condition, and by to C ₃Short circuit change oscillation frequency to reach the purpose of indicating fault, its weak point is: 1.R ₀Power consumption is big, temperature rise, and Der Blink und Abblendschalter is easily because of heat damage, and 2. the circuit structure complexity does not 3. have mu balanced circuit, and the power line voltage rising can cause the device scaling loss, and flash rate also changes thereupon simultaneously, produces erroneous judgement, may burn because of the pin reversal connection when 4. Der Blink und Abblendschalter uses.

The purpose of this utility model designs a kind of energy-conservation exactly, and long service life is easy to use, electronic flash relay simple in structure.

The purpose of this utility model realizes by following structure: electronic flash relay includes by NE555, R ₅, R ₂And C ₁The magnet oscillator circuit of forming and be: in circuit, be connected to protective circuit of voltage regulation, damage device when preventing three output of this flasher relay pin misconnection, be connected to by divider resistance R at 5 pin of NE555 with relay 1J, its principal character that 3 pin of NE555 join ₄And R ₃And make the dry-reed tube of its electric current open and close form bleeder circuit, on power lead, be connected to the GJ of a control dry-reed tube break-make ₁The principle of work of this flasher relay is as follows: 2 of NE555,6 pin are active potential when power connection, and 3 pin output HIGH voltage 1J adhesive mouth L have positive voltage, and external steering indicating light is bright, and positive voltage passes through R simultaneously ₅To C ₁Charging, 2,6 pin current potentials raise gradually with charging, and output switching activity discharges for low level 1J when its current potential rises to the threshold voltage of NE555, and steering indicating light goes out, C ₁Pass through R ₂, R ₅With the discharge of loop such as external steering indicating light, the output high level for the treatment of to overturn again when terminal voltage is lower than threshold values, realize vibration, GJ when normal operation so repeatedly ₁Make the dry-reed tube adhesive, 5 pin current potentials are R ₄And R ₃Partial pressure value, the oscillation frequency that higher relatively 5 pin current potential NE555 produce normal (about 85 times/minute) is when steering indicating light has a bulb damage or bad contact and flows through GJ when not working ₁Electric current reduce, it is obstructed that dry-reed tube is ended, at this moment 5 pin current potentials reduce, the oscillation frequency of NE555 will significantly rise and reach 190 times/minute, flash rate at this moment just can have fault by clear and definite alerting driver steering indicating light, needs repairing.

The utility model compared with prior art has following advantage:

1. adopt common NE555 integrated package and dry-reed tube current detection switch, thus have simple in structure, no heat element, power consumption is little, advantages such as long service life.

2. owing to be provided with protective circuit of voltage regulation, thereby use more conveniently, avoided burning and waited deficiency because of the flasher relay misconnection.

3. failure frequency and normal flash rate can be adjusted respectively, are independent of each other, and are beneficial to manufacturing.
