されていない。 A conventional line testing handset has a configuration as shown in Figure 1. When using this testing handset, connect the alligator clip 3 to the lines L 1 and L 2 and press the dial to call the test stand. Pulses are generated by repeatedly connecting and disconnecting the alligator clip 3 or repeatedly connecting and disconnecting the connector 4. When the monitor is used only for receiving calls, the connectors 4 are used in a state where they are separated from each other. In FIG. 2, the transmitter T is disconnected from the lines L 1 and L 2 with the connector 4 unplugged. This transmitter/receiver for track testing is often used on main distribution boards, on poles, in manholes, underground caverns, etc. If the connector 4 is left hanging in a disconnected state, it may get caught on the material, etc., or the exposed conductor may be exposed. It is dangerous because it may come into contact with other tracks. Furthermore, when the dial pulse is generated by connecting or disconnecting the connector 4, the operator must operate with both hands, which may be dangerous if the operator is climbing on a pillar. Furthermore, since the plug and jack of the connector 4 are both connected to unstable cords, it is extremely difficult to generate pulses having the required pulse width and pulse interval. Furthermore, in order to generate dial pulses using an alligator clip, there were drawbacks such as the difficulty of maintaining a stable pulse interval and the operation of pinching the conductor after the last pulse, which required skill. There is also a type in which the connector 4 in Figure 1 is replaced with a pull-down switch (see Utility Model Application No. 49-79107), but the switch is installed in an unstable location, making it impossible to operate with one hand. However, even when operated with both hands, one side is not fixed, so erroneous pulse transmission is likely to occur, so it has not been put to practical use.

4 is a band, 15 is a case in which the output end of the transmitter 11 and the input end of the receiver 12 are housed, 16 is a push-button type non-lock switch that is always in contact, 17 is a slide type switch, and 18, 19, 20 are resistance, 2
1 is a capacitor, and 22 is a varistor. The switches 16, 17, the resistor 18, and the transmitter 11 form a DC loop connected between the lines L1 and L2 . The capacitor 21 is used to block direct current flowing to the earphone, and the varistor is used to reduce the click current flowing to the earphone 22. Resistors 18, 19, and 20 form a bridge circuit for improving sidetone. Switches 16 and 17 are provided on the upper surface of the case 15 as shown in b. The switch 17 disconnects the transmitter 11 and may be connected in series with the transmitter 11. However, if the switch 17 is connected in series with the transmitter 11, when the transmitter 11 is disconnected, the resistors 19 and 20 It is necessary to increase the capacitance because DC flows through it, and resistor 1 is installed in the receiver circuit.
8 and 19 are connected in parallel, so that the receiving volume becomes low. For this reason, the switch 17 is preferably connected in series with the resistor 18.

The transmitter 11 is connected between the connection point and the capacitor 21.
When the switch 17 is closed, a DC current is supplied to the transmitter 11, and in this state, an AC signal is also supplied to the receiver 12 without any problem. Further, when the switch 17 is opened, the direct current to the transmitter 11 is blocked, and the alternating current signal is continuously supplied to the receiver 12. If the clip terminal 13 is a "clip terminal" which the inventor of the present application filed on the same date, it is possible to make a secure connection even if there is a slight difference in the dimensions of the objects to be connected.

の接続ミスも生じない効果がある。 As explained in detail above, the line testing handset of the present invention is equipped with a cut-off switch when only receiving calls, so there is no need for a connector, and since the device does not get dangling during use, it can be used at busy sites. Safe to use. Furthermore, the dial pulse for calling the test stand is generated by intermittent switching of a switch attached to the case, which is kept stable during use, making it possible to generate pulses with a stable pulse width and pulse interval.
The risk of incorrect connection is extremely low, and it can be easily operated with one hand even when wearing gloves.Therefore, it is safe even on a pole without having to take both hands off, and there is no need to operate with an alligator clip as with conventional ones. This has the effect of preventing connection errors after the final pulse.
