RU6377U1 - LAMP INTEGRITY CONTROL DEVICE - Google Patents

Abstract

A device for monitoring the integrity of lamps, containing two printed circuit boards with electrical circuit elements, inter-circuit jumpers and pins for connecting to the vehicle's wiring network, a housing and a cover, characterized in that the pins are configured and pressed into the boards, a special microcircuit is installed in the wiring diagram, current sensors made of high resistance wire, while the device is made in dimensions of 28 x 50 x 30 mm ± 10% excluding pins.

Description

DEVICE FOR POWER CONTROL

The device is designed to signal the failure of the brake lights and marker lights, both in the on and in the off state.

Known interrupter direction indicators and alarm 492.3747. The chopper is produced by JSC AVAR of Pskov TU 37.469.002-86. See the product catalog of ABAR JSC Vneshtorgizdat publishing house 1992

A reed switch is installed in the breaker for monitoring the health of direction indicators,

 The disadvantage of a reed switch is a false alarm or loss of control functions when exposed to external electromagnetic fields.,

Known relay health monitoring lamps 4402.3747,., B ,,, produced by AVAR Pskov TU 37.003.1177-83. See the product catalog of ABAR JSC Pskov, Vneshtorgizdat 1992

The relay consists of two printed circuit boards connected by jumpers. There are five reed switches, radio elements, pins for connecting to a vehicle

in LAZ

The disadvantages of the relay on the reed switches are:

- complex triggering or loss of control function when external electromagnetic fields are applied from nearby electromechanical relays or other products with inductive loads;

- a significant number of copper winding wires, In the proposed device integrity control lamps

technical result - stable laglp integrity control in the absence of false positives is achieved as follows:

- a special microcircuit is installed in the electrical circuit;

- current sensors are made of high resistance wire;

-pins for connection to the onboard network are configured and pressed into printed

- the device is made in dimensions of 28 x 50 x 30 mm - 10 excluding pins.

On Fig, 1 shows printed circuit boards in expanded form lying in the same plane.

Figure 2 shows the device assembly with a breakout.

In Fig. 3, a pin with a configuration pressed into a printed circuit board.

The proposed device consists of two printed circuit boards I, 2. The boards are interconnected by rewires 3, on the boards I, 2 there are elements of the electric cxeivrM - resistors 4, capacitors 5, current sensors from high-resistance wire 6, special circuitry 7, resistors 8, pins S for connecting to the vehicle side panel. The pins E are made with a configuration of 10 and are pressed into the boards I, 2. The device has a housing II, a cover 12. The proposed device is installed with pins in the unit, relay and fuses (not shown in the drawing). The device using a special chip 7 evaluates the flow of current in the circuit and its value. In the marker lamps (not shown in the drawing), the presence of a flowing current is evaluated. For stop lamps (not shown in the drawing), not only the presence of the pierced current but also its value is evaluated. In the event that the Lalsha is faulty, a signal is sent to the control lamp on the dashboard (not shown) of the vehicle. The device works both with the engine turned on and the car engine turned off. The proposed device is technologically simpler, less material-intensive, fiberglass less than 30, plastics less than 15, excluded winding wires, reduced labor costs for assembly.
