Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a failure determination device for promptly finding a failure location when a system telephone device fails.

[Conventional technology]

FIG. 2 is a block diagram of an example of a conventional system telephone device. In FIG. 2, 20 is a main unit, 20P is a modular plug, 21 is a master telephone attached to the main unit 20, 22, 23, 24 ...
22J, 23J, 24J are modular jacks installed at the child device installation locations, 22P, 23P, 24P are modular plugs connected to the respective child devices, and 25 is wiring. The number of wires 25 differs depending on the number of station lines. In addition to the number of station lines, two control lines are wired to each slave unit, and a slave unit is selectively called by a signal sent from the main unit 20.

When the system telephone device as described above fails, conventionally, to determine the location of failure, remove all the modular plugs of the main unit 20 and the slave units 22, 23, 24, and place between the main unit and the slave unit installation location. Contact each other to check the
And the slaves 22, 23, 24 were temporarily wired and operated, the faulty part was judged, and repair was performed.

[Problems to be solved by the device]

However, in the system telephone device, the main device, the circuit of the cordless handset and the wiring form differ depending on the number of station lines to be connected, the number of cordless handsets, the control method (analog type or digital type) for calling the cordless handsets, When the telephone device is broken down, it is necessary to deal with it by different methods depending on the model of the main device. Especially when wiring and inspecting it, it takes a lot of time and manpower to prepare a modular connector for the wiring. However, there is a problem that the wiring material is wasted and the wiring material is wasted.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned problems and provide a device capable of promptly finding a faulty part corresponding to all currently used main units of the models.

[Means for solving the problem]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a failure determination device for a system telephone device including a main device connected to one or a plurality of telephone lines and an intercom line, and a plurality of slave phones controlled by the main device. , A plurality of modular jacks that connect the telephone line and the intercom line, different types of modular jacks that can be connected to correspond to the different types of main devices, and a plurality of slave phones that correspond to the different types of main devices. A plurality of modular jacks of different types to be connected are provided, and the modular jacks are wired in the same manner as the wiring configuration of the system telephone device, and are housed in a small and lightweight portable type body. is there.

[Action]

Since the present invention is configured as described above, regardless of the model of the system telephone device, if the failure determination device of the present invention is carried, it is possible to immediately determine the failure point without performing different preparation work for each model. Since it can be started, trouble repair can be performed quickly.

〔Example〕

FIG. 1 (a) is a block diagram of an embodiment of the present invention.
FIG. 3B is an explanatory view of an embodiment of the present invention, FIG. 3 is a connection diagram of the embodiment of the present invention, and FIG. 4 is a perspective view showing a structure of the embodiment of the present invention.

In the above figures, 1J is a station line 1, 2J is a station line 2, 3J is a modular jack for connecting doorphones, 4J and 5J are modular jacks for connecting main devices of different methods, and 6J and 7J are different methods. Modular jack for main phone connection, 8J1
8J4, 9J1 to 9J4, 10J1 to 10J4, 11J1 to 11J4, 12J1 to 12J4 are modular jacks for connecting slave units corresponding to the various main devices and main telephones. Further, each number with P attached thereto is a modular plug inserted into each modular jack.

As shown in FIG. 1 (a), FIG. 3, and FIG. 4, the modular jack is attached to one panel, and the station line 1,
A modular jack that connects the station line 2 and the intercom line,
The modular jack for connecting each main device and the modular jack for connecting a plurality of cordless handsets corresponding to the main device are wired in the same manner as the wiring configuration of the system telephone device in use, and (Fig. 4), small,
It is lightweight and easy to carry. FIG. 1 (b) is an explanatory view of an embodiment of the present invention. As an example, it is generated in a system telephone device including a main unit 10 which accommodates two office lines and an intercom line and can selectively call n slave units. It is an explanatory view in the case of applying the failure judging device of the present invention in order to search the cause of the failure which occurred. As shown in the figure, place a failure detector near the main device installation location and connect the modular plugs 1P, 2P, 3P connected to the office line and doorphone line to the modular jack 1
J, 2J, 3J, and also the modular plugs 4P1, 4P2, 4P3 from the main device 10 are inserted into the modular jack 4J (three ports). In addition, the cordless handset is pulled out from the modular jack at the installation location by inserting the modular plugs 8P1 to 8Pn connected to the cordless handset into the fault detectors 8J1 to 8J4.
The system telephone device is immediately configured. Therefore, when operating the main unit to perform a call test of each slave unit, there is no need to communicate with the slave unit installation place as in the past, and the cause of the failure is Whether it is in the main unit, in the wiring, or in a specific child device, etc. can be promptly determined and countermeasures can be taken.

Needless to say, the type and number of the modular jacks attached to the failure determination device of the present invention are not limited to those in the above embodiment, and can be arbitrarily changed as necessary.

[Effect of device]

As described above in detail, the failure determination device of the present invention can be applied to all currently used system telephone devices, and can be made compact and lightweight to be portable and convenient. After receiving the information, it is possible to expect an effect that it can be immediately dispatched, and a small number of people can quickly determine the failure location and perform the failure repair at the installation site without performing any special preparation work.
