CONSTITUTION:The connecting plug 10 of an adaptor 11 is drawn out of the connector of a tester body 1, and connected to a connector 13 provided indoors. Also, a connecting plug 7 connected to one end of an inspecting cord connected to the body 1 is connected to other connector 14 provided indoors, and wirings A1-C1, A4-C4 to the connector 13 are inspected. For instance, at the time of inspecting the connecting system of the wiring A1 and A4, when a switch SW1 and SW1' are set to a closed state, a current from a power source V is conducted in order of a terminal A, the wiring A1, terminals A2, A3 of the adapter 11 and terminals A4, A5, and a pilot lamp 3 is lighted, therefore, it can be confirmed that the wiring is correct. On the contrary, when the wiring is wrong, or when it is disconnected, other switches SW2, SW2', SW3, and SW3' are in an open state and the pilot lamp 3 is not lighted, therefore, it can be confirmed easily.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

Fig. 1 shows an embodiment in which the present invention is used to inspect the wiring of a connector having three connection systems. is equipped with three switches 2a, 2b, 2c and an indicator light 3 consisting of a light emitting diode, and one side 1b has three modular connectors 4.5.6.
is arranged, and the connector l has connection plugs 7.8 on both ends.
An adapter 11 having a connecting plug 10 connected to one end thereof is inserted into the connector 6, respectively. As shown in FIG. 2, this adapter 11 connects terminals 2 and A3 of the same connection system. E2 and 3133 degrees C2 and C3 are respectively internally connected to each other. In addition, as shown in Fig. 2, the tester main body (1 yen) houses a power supply V and a verification device, and the verification device has a terminal A on the + side of the power supply V.

Switches SWI, SW2 and 8W3 connected to terminals A5.B and C are connected to terminals A5. B5. Switch 8W1 connected to C5
', sw2';sw3' are provided.

Note that it is desirable that the switches SWI and 19W1, SW2 and SW2', and SW3 and SW3' work together, respectively.

To use the tester configured as described above, first remove the connection plug 10 of the adapter 11 shown in FIG. (See figure) Connect the IC. At this time, it is desirable that the connector 13 be closest to the central office line. Then, the connection plug 7 connected to one end of the test cord 9 connected to the tester main body 1 is connected to any other connector 14 (see FIG. 2) installed indoors, and the connector 13 Wiring AI between.

B1. Inspect C1, C4, B4 and Person 4. For example, to inspect the connection system for wiring person 1 and wiring person 4, press switch 2a shown in FIG.
If 1' is in the closed state, the current from the power source V will be 1. Terminal 21 of adapter 11 flows through terminal 21 3, terminal 4, and terminal A5 in this order, and indicator light 3 lights up, so it can be confirmed that the wiring is correct. On the other hand, if the wiring is incorrect or there is a disconnection, try another switch 8W2.
8W2', 8W3 SW3' are in the open state, and the current from the power source (2) does not flow to the indicator light 3, so the indicator light 3 does not light up, so it can be easily confirmed. In this embodiment, a diode D is connected between the switch 8W1' and the terminal 5, between the switch 8W2' and the terminal B5, and between the switch 8W3' and the terminal C5, so that the wiring of the same system is connected. Wiring errors can also be confirmed when the terminals are crossed and the positive and negative terminals are reversely connected. Furthermore, by setting switch 2b or 2(1!), wiring errors or disconnections in other systems can be similarly inspected.

9 In this embodiment, an indicator light is used as a confirmation means, but a buzzer may be used or it may be used in combination with a buzzer. Also, the connector 5 provided on the side surface 1b of the tester body 1 is a plug for connecting the test cord 9. 7, or by inserting the connecting plug 10 of the adapter U, it is possible to inspect the power supply V or the disconnection of the adapter 11 (not shown).

Furthermore, FIG. 3 shows another embodiment of the present invention,
The shapes of the tester body, adapter, and test cord are almost the same as those of the previous embodiment (not shown), and the adapter ■ has terminals A2 and 3 of the same connection system.B2 and B3.C2 and C are the diodes DI. .

The output side of is High when A and person 5 are Hlfh.
In this case, C5 and B5 are LOW, and the AND circuit Q
The output side of 5 is) 11th when B, B5 and person 5 are Hi9h and C5 is LOW, and furthermore, AN
The output side of the D circuit Q6 becomes High when all of C, C5, and the person 5 are I (ifh).In addition, in this embodiment, the output side of the AND circuit Q4.C5e C6 is connected to the Oa circuit Q7. Further, a light emitting diode LED4 and a buzzer BZ2 are connected to the output side of an exclusive OR circuit Q9 which receives the respective outputs of the OR circuit Q8 and the zero circuit Q7 as inputs. To use, as in the embodiment shown in FIGS. 1 and 2, connect the connection plug 10 of the adapter 11 to the connector 13 (see FIG. 3) installed indoors, and connect the tester main body 1. Connect the connection plug 7 connected to one end of the inspection cord 9 connected to one of the connectors 14.For example, to inspect the connection system of the wiring A1 and A4, set the SWI to the closed state. The current from the power supply V flows in the order of wire 1, terminal A2, diode D3, terminal 3, and wire A4, making terminal 5 Hiyh.Also, at this time, terminal 5 is Hirh, but terminals C5 and B5 are LOW. Therefore, the output side of AND circuit Q4 becomes Hiyh.
Then, LBDI lights up and buzzer BZ 1 operates. still.

Terminals B and B5 are LO1, 17, and terminals C and C5 are LQIV, so light emitting diode IJD2 and LED 3 do not light up. Furthermore, wiring B1 and B
To test the connection system of No. 4, it is sufficient to close 8W2, in this case terminal B.

B5 and A5 become High and light emitting diode LED

Furthermore, to inspect the connection system of wiring C1 and C4,
When W 3 is closed, terminals C, C5, B5 and person 5 become Hi Vh, and the light emitting diode LED 3 A turns on. Furthermore, if the wires Bl and C1 are mistakenly connected in a crossed manner as shown by the chain line in FIG. B.S.
Person 5 each becomes high and the light emitting diode Lll

3 is in the closed state, an abnormality is notified in the same way.
Therefore, according to this embodiment, the same connection systems are connected via diodes, and the adapter that connects the respective systems via diodes is connected, and the current flowing to this adapter is wired by a confirmation mechanism using a digital circuit. Even if there is a wiring error where multiple connection systems intersect in a complicated manner, it can be easily and reliably detected. In this embodiment, a case is shown in which the wiring for the connection ports of three connection systems is inspected, but it can be similarly carried out in the case of two connection systems or more than three connection systems.

Furthermore, FIG. 4 shows a further embodiment of the present invention, and the overall structure and method of use are almost the same as the embodiment shown in FIG.
A logic circuit consisting of a complementer IJMO8 is connected to B and C. Therefore, unlike the embodiment shown in FIG.
2.8W3 (see Figure 3) allows current to flow through each terminal in sequence, B, C without operating it, which is even more convenient.
