Abstract
The utility model discloses a novel motor vehicle relay with indication lamps. The motor vehicle relay comprises a shell and pins extending from the inside of the shell, wherein, a grounding wire is arranged inside the shell and is led out of the shell and connected to a grounding part in a circuit of a motor vehicle; a visible part in the shell is provided with indication lamps which correspond to each pin; the outer sides, corresponding to each indication lamp, of the shell are respectively marked with the pin sign for the corresponding pin and the anode of each indication lamp is connected with the corresponding pin and the cathode thereof is connected with the grounding wire. When in use, if a pin of the motor vehicle relay has the working voltage, the corresponding indication lamp can be lighted up, vice versa; thereby, the maintenance staff can detect the corresponding faults such as the faults occurring in the load, the relay or the circuit accurately according to the lighting of an LED D1, and the faults are easily detectable, the examination and the maintenance are convenient and the troubleshooting is quick.
Description
Technical field
The utility model relates to a kind of relay, especially a kind of motor vehicle relay.
Background technology
Various loads in the motor circuit all connect with relay as loudspeaker, direction indicator lamp etc., when faults such as loudspeaker do not ring or direction indicator lamp does not work occurring, often can not in time measure location of fault, and it is very inconvenient to detect maintenance.
The utility model content
The purpose of this utility model provides a kind of novel band display machines motor-car relay that can indicate the operating state of motor vehicle relay comprehensively and show corresponding motor circuit situation.
The technical solution of the utility model is such: the motor vehicle relay of novel band display lamp, comprise that housing reaches by each pin of drawing in the housing, be provided with earth connection in the above-mentioned housing, this earth connection is drawn the ground connection place that above-mentioned housing is external to motor circuit, viewing position place in the above-mentioned housing is provided with and the corresponding indicator light of above-mentioned each pin, indicate the pin number of each corresponding pin on the pairing hull outside face of above-mentioned each indicator light respectively, correspondence is connected on above-mentioned each pin the positive pole of above-mentioned each indicator light respectively, negative pole connects above-mentioned earth connection respectively.
Above-mentioned housing and the corresponding position of above-mentioned each indicator light are respectively arranged with transparent window.
Above-mentioned each indicator light is in series with current-limiting resistance respectively.
Above-mentioned each indicator light is in series with current-limiting resistance and voltage-stabiliser tube respectively.
After adopting such scheme, the beneficial effects of the utility model are: when motor vehicle relay pin of the present utility model produces operating voltage, corresponding indicator light will be connected indication, which pin of motor vehicle relay does not have operating voltage, corresponding indicator light just can not be bright, the maintenance personal is according to the indicator light situation, can accurately judge corresponding failure condition, as load itself or relay or line fault, maintenance is convenient rapidly, the time of fixing a breakdown significantly reduces, and phenomenon of the failure is directly perceived, comes into plain view.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Fig. 2 is an indicator light distribution schematic diagram of the present utility model.
Embodiment
The motor vehicle relay of novel band display lamp of the present utility model, European relay with five pins is an example, the pin of its five pins number is respectively 87,86,30,85,87a, wherein 86,85 pairing pins are connected to the positive terminal and the negative pole end of relay coil, 30 pairing pins are connected in battery power, and 87, the pairing pin of 87a is connected to relay normally open output and normally closed output.
As shown in Figure 1, band display lamp motor vehicle relay of the present utility model comprises housing 1 and respectively by the pin 87,86,30,85, the 87a that draw in the housing, has additional earth connection 2 in the housing 1, and earth connection 2 is drawn the ground connection place that housing 1 is external to motor circuit.Pin 87,86,30,85,87a are electrically connected with indicating circuit respectively in housing, each indicating circuit comprises light-emitting diode D1, current-limiting resistance R and voltage-stabiliser tube D2 respectively, the positive pole of light-emitting diode D1 in each indicating circuit is connected on each corresponding pin, the negative pole positive pole of series limiting resistor R and voltage-stabiliser tube D2 successively, and the negative pole of voltage-stabiliser tube D2 connects respectively on the earth connection 2.
As shown in Figure 2, the front of housing 1 (that promptly relative with pin lateral surface) is provided with and five pins 87,86,30,85, the corresponding transparent window 11,12,13,14,15 of the pairing light-emitting diode D1 of 87a, and the other mark respectively of transparent window 11,12,13,14,15 has and five pins 87,86,30,85, the corresponding pin of 87a number.
When each pin of motor vehicle relay of the present utility model produces operating voltage, corresponding light-emitting diode D1 will connect luminous indication, which pin of motor vehicle relay does not have operating voltage, corresponding light-emitting diode D1 just can not be bright, the maintenance personal is according to the luminous situation of light-emitting diode D1, can accurately judge corresponding failure condition, as load itself or relay or line fault, maintenance is convenient rapidly, the time of fixing a breakdown significantly reduces, phenomenon of the failure is directly perceived, comes into plain view.
