If the motor does not start even after pressing a, the following steps should be taken to find the location of the failure. First, it is assumed that there is no abnormality in the power supply circuit to the motor itself. Workers usually use a voltmeter, tester, lamp, etc. to find the fault, but as shown in Figure 2,
To explain when using a tester, one lead wire of the tester is connected to the T phase on the power supply side, and the other lead wire is connected to each point A, B, C to F and H, J to N. The location of the failure was discovered by sequentially moving the parts and examining their potentials. In this work, if the voltage measurement range of the tester itself is not set in advance to a large enough margin, there is a risk of burnout, and there is also the drawback that it can easily be damaged if it falls from your hand. The same applies when using a voltmeter. In the case of lamps, there is a drawback that lamps with different ratings must be prepared for each circuit voltage.

能となる。 SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a check device that eliminates the drawbacks of conventional devices, is easy to handle, and can detect failures within a short period of time. According to the present invention, two display neon lamps are housed in a hollow cylindrical insulating case with a contact needle fixed to one end so that their blinking states can be visually observed from the outside. Connect the neon lamps in series and connect the points between them to the contact needle, connect lead wires to the other terminals of the neon lamps through resistors, and connect these lead wires to the outside from the other end of the case. This is accomplished by constructing an electric circuit check device by extracting the information. In this invention, two wires are connected in series by simply connecting the lead wire to the control power source of the electric circuit in which a defective conduction point is to be detected, and touching the contact needle to an appropriate point in the electric circuit. It is possible to detect poor continuity by visually observing the blinking state of the neon lamps, and by connecting two neon lamps in series, the lead wire is only connected to the control power source of the electric circuit. It can also be used as a voltage detector to detect whether an appropriate voltage is being applied to the control power source of an electric circuit.

As well as housing LM 1 and LM 2 and resistors R 1 and R 2 ,
The connections are made as shown in the figure, and a contact needle 8 made of a conductor is attached to the portion corresponding to the tip of the pencil lead. Lead wires 2 and 3 are connected to the resistors R 1 and R 2 , respectively, and alligator-shaped clips 4 and 5 are connected to the tips of the lead wires, which are covered with insulating tubes. Resistors R 1 and R 2 are of high resistance, 300kΩ in the example.
and 500 kΩ were used. In order to make the display neon lamps LM 1 and LM 2 correspond to the lead wires 2 and 3, the lead wires 2 and 3 are colored differently, or the insulating tubes 6 and 7 are colored differently.

Assume that the motor does not start even if BS2a is pressed, and that there is no abnormality in the motor's power supply circuit itself. In such a case, as shown in FIG. 3, the check device according to the present invention is connected, the contact needle 8 is placed at point D, and the switch BS2a is pressed. As a result, if the display neon lamp LM 1 goes out and LM 2 lights up, it can be seen that the failure category is on the side of point D or point G. Therefore, the next step is to move the contact needle 8 to E.
Let's move it to point F. At point E, contact
Even if AXa is closed, if lamp LM 1 is still off, move to point F. If the lamp LM 1 turns on and the lamp LM 2 turns off at this point F, it is discovered that the coils M and C are disconnected.

電器としても役立つ。 In addition, in the case of a failure in which the coils M and C cannot be self-retained, place the contact needle 8 on point J, and
Check whether LM 1 or LM 2 lights up. If the lamp LM 1 lights up, it is clear that the contact La part is defective. On the other hand, if the contact La is short-circuited or activated and the contact needle 8 is applied to the K point, and in this state the lamp LM 1 goes out and LM 2 lights up, it is known that the coil LX is disconnected. Note that when the check device according to the present invention has its lead wires 2 and 3 connected to the power supplies R and T, the neon lamp for display
LM 1 and LM 2 can be connected in series and both can be lit. This check device therefore also serves as a voltage detector.

していけば不良個所が迅速に発見できる。 As described above, if the device according to the present invention is used, two neon lamps are connected in series across both ends of the electrical circuit in which a conduction failure point is to be found, so the point between these lamps (i.e. When the contact needle (contact needle) is connected to an appropriate point in the middle of the electric circuit, one of the two lamps that are lit at first goes out, so the power supply R between the contact point of the contact needle and the other lamp that is lit is turned off. Or, it is immediately obvious that the circuit between T and T is in the poor conduction range. In other words, by simply touching the contact needle, the defective area and good area of the circuit can be determined by the flashing of two lamps, and if the defective area is further converged, the defective area can be quickly discovered.

ある。 Also, since it is a neon lamp, there is no risk of damaging the device like a voltmeter or tester even if the circuit voltage changes without changing the voltage range.
It won't break even if you accidentally drop it. Furthermore, a voltmeter,
It is much cheaper than testers and has practical value.
