Abstract

The utility model discloses a multifunction torch testing device. Transfer switches 2, illuminating diodes 3, and jacks 4 are arranged at the inside of the back cover of a common torch on a piece of the circuit board. The three elements are fixed on the back seat of the torch by connecting devices, the three elements are arranged in series in the circuit of the torch, and the three elements are formed into a hoop with other elements in the torch. Test wires 10 are arranged at the inside of the jacks 4, and the test wires 10 can be switched in the tested appliances. The utility model has the advantages of simple structure, one object with, multiple functions, convenient portability.,low cost and wide purpose.

Description

Multifunction torch testing device

The utility model relates to a kind of electrical testing instrument, particularly a kind of multifunctional electric torch tester.

Known electrical testing instrument, as multimeter, volume is big, carries inconvenience, and cost is higher, be not suitable for average family and use, and the torch that people use does not possess test function again.

This reality is made the shortcoming that novel purpose promptly is to overcome prior art, and a kind of multifunctional electric torch tester is provided, and this tester one-object-many-purposes not only can be used as the torch illumination but also can test electrical equipment, and is easy to use, cheap, easy to carry.

The purpose of this utility model reaches by following measure, switch 2 is installed in the bonnet of common torch, light emitting diode 3, jack 4, these elements are installed on the circuit board, and circuit board is fixed on the back seat of torch by coupling arrangement, above-mentioned three elements all are connected in the circuit of torch, form the loop with other element of torch, be provided with p-wire 10 in the jack 4, p-wire 10 can insert circuit-under-test.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the cut-open view of torch tester

Fig. 2 is the sectional view of the element in the torch tester bonnet

Fig. 3 is the circuit diagram of torch tester

Among Fig. 1,1 is the torch bonnet, and 2 is switch, and 3 is light emitting diode, 4 is jack, they all are arranged in the torch bonnet, are installed on the circuit board, and the sectional view of elements on circuit board as shown in Figure 2, jack 4 has two, be provided with p-wire 10 in the jack 4, p-wire 10 is by plug 11, connecting line 12, probe 13 is formed, what insert in the jack is plug 11, probe 13 with contacted by electricity measurer, circuit board is fixed on the back seat of torch by

screw

5,6 is the battery of torch, 7 is the torch body, and 8 is switch, and 9 is bulb.

Fig. 3 is the circuit diagram of torch tester, when this tester is used alone as torch, switch 2 and A point is closed, switch 8 closed bulbs are bright, any one switch disconnects, bulb does not all work, when this tester is used to test, insert test plug 11 in the jack, probe 13 with contacted by electricity measurer, cut-off switch 8 just can be tested, tested electrical equipment resistance was in 10 Europe when cell voltage was 3V, switch 2 is closed with the A point, the electrical equipment break-make is designated as bulb, by the electricity measurer resistance in 10 Europe～1000 Europe, switch 2 is connected on the B point, the electrical equipment break-make is designated as light emitting diode, this tester can be used for each family and check electrical equipment and fuse in uncharged circuit, plug, the break-make of socket etc., when not having multimeter and special test equipment, maintenance household electrical appliance and judgement diode, radio device interpolars such as triode just, oppositely logical, disconnected situation, the electrician can carry and be used for illumination and check electrical equipment and motor, each winding such as transformer logical, the fault of disconnected and winding and winding and casing short circuit also can be used for driver's automobile generation electric fault and check that circuit and maintenance at night throw light in road.

Can find out from top narration, the utlity model has following advantage: the scope of application is wide, cost is low, simple in structure, easy to carry, one-object-many-purposes.
