Abstract
The utility model relates to an automobile main power supply test meter, comprising a meter head V and a test pencil B2 which is connected with the meter head V. An anode of the meter head V is connected with a test pencil B1 through a transfer switch K1; a load resistor R1 is connected between a selecting end of the transfer switch K1 and the meter head V; a battery E, a switch K2 and a test pencil B3 are connected in series with the anode of the meter head to form a circuit connecting or breaking detecting device. The utility model has the advantages that it has a simple circuit, small volume weight, low cost, variety functions and it is convenient to carry; besides, it can not only test the working voltage and load starting voltage of the main electric power source of a motor-vehicle, it can also test the connecting or breaking of the circuit. It is simple to operate; therefore, it can satisfy the request of the main electric power source of the motor-vehicle and the simple or comprehensive testing of the circuit.
Description
Technical field: the utility model relates to the detection table of a kind of machines motor-car general supply and related circuit.
Background technology: the present circuit of simple and easy comprehensive detection motor vehicle and the portable instrument of general supply of not being used for, some driver adopts multimeter as pick-up unit, and volume is big, the price height, inconvenient driver portably uses with car, and use is still complicated, and the function that can utilize is few.Now portable accumulator detector has been arranged, can detect the operating voltage and the load starting voltage of accumulator, but function singleness can not satisfy the requirement of power sources of motor vehicle and the simple and easy comprehensive detection of circuit.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of diverse in function, and motor vehicle general supply easy to carry detects table.
The utility model comprises gauge outfit V and is connected the test pencil B2 of its negative pole, the positive pole of gauge outfit V connects test pencil B1 by switch K1, be connected with pull-up resistor R1 between the selecting side of switch K1 and the gauge outfit V, the positive pole of gauge outfit V also is serially connected with battery E, K switch 2 and test pencil B3, forming circuit switching detection device.
Circuit of the present utility model is simple, volume weight is little, cost is low, easy to carry, and diverse in function, but the not only operating voltage of machines motor-car general supply and load starting voltage, the break-make of all right testing circuit, operate very simply, can satisfy the requirement of motor vehicle general supply and the simple and easy comprehensive detection of circuit.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the circuit connection diagram of embodiment;
Fig. 2 is the main synoptic diagram of embodiment.
Embodiment: as shown in the figure, gauge outfit V negative pole is connected with test pencil B2, and the positive pole of gauge outfit V connects test pencil B1 by switch K1, is connected with pull-up resistor R1 between the selecting side of switch K1 and the gauge outfit V, constitutes the general supply voltage check device.The positive pole of gauge outfit V also is serially connected with battery E, K switch 2 and test pencil B3, forming circuit switching detection device.When need detecting general supply mark voltage, switch K1 is beaten a end to direct connection gauge outfit V, test pencil B1 and B2 are connected on respectively on the general supply both positive and negative polarity and can detect.If switch K1 is beaten a end to bringing onto load resistance R 1, utilize test pencil B1 and B2 can measure general supply load starting voltage, whether can measure when motor vehicle can't start is the general supply reason.Need whether the circuit connection is communicated with on the machines motor-car, K switch 2 closures can be utilized test pencil B3 and B2 to be connected the circuit two ends and can be detected, ifs circuit is communicated with then can make battery E conducting that voltage is provided, and gauge outfit V shows, otherwise circuit is broken string.
In practice, detect general supply voltage and testing circuit on off operating mode and generally carry out respectively, present embodiment also is connected with test pencil B4 at the negative pole of gauge outfit V, and B3 is supporting with test pencil, and test pencil B2 adopts clip, and B1 is supporting with test pencil.Test pencil B1 and B2 like this, test pencil B3 and B4 can be arranged in a place, when detecting, be difficult for obscuring, handled easily, and test pencil B2 uses clip more convenient when detecting general supply.Switch K1 of the present utility model and pull-up resistor R1, and battery E and K switch 2 are arranged in the positive terminal of gauge outfit V, in fact be arranged in negative pole end or two ends and arrange the measuring ability that can carry out equally separately respectively, at circuit is the technical scheme that is equal to fully, but with the standard of switch arrangement in positive terminal coincidence detection instrument, connection when also making things convenient for situation such as negative pole end ground connection, handled easily uses.
The branch road that present embodiment also has K switch 3 and miniature bulb L to be connected into is connected in parallel on battery E two ends, constitutes emergent litillumination devices, connects down K switch 3 so when needed, and miniature bulb L can be used as the illumination torch, and function is more various, uses more convenient.And, also can be on gauge outfit V the branch road of light emitting diode LED in parallel and current-limiting resistance R2 serial connection, LED all can be luminous during gauge outfit V work, observes gauge outfit V and can know more and make things convenient for when insufficient light, prevents to misread.
