Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a cord set for use in communication equipment that requires a low-voltage power source, in which a microphone, speaker, etc. are incorporated into a telephone.

(Prior Art) A communication device (hereinafter referred to as a speakerphone) in which a microphone and a speaker are incorporated into a telephone uses a microphone and a speaker, and thus requires a low-voltage power source for use. Therefore, conventionally, as shown in Fig. 4, an insulated telephone wire core 1 is connected to a speakerphone 3 via a telephone connection terminal case 2, 2', and then a low voltage AC100V is connected to a commercial 100V power outlet 4. A voltage converter 5 was inserted, and the insulated wire cores 6 of the converted low-voltage power source were connected to speakerphones.

In such a state, the telephone insulated wire core and the low-voltage power insulated wire core are separate, making handling difficult and undesirable due to their untidy appearance. Depending on the length of the connected insulated wire cores, it was difficult to move them.

(The problem that the idea attempts to solve) The present invention improves the following points.

There is no need to prepare insulated wire cores for telephones and insulated wire cores for low-voltage power separately and connect them to the speakerphone.
Cover all at once and use as a composite cord.

A combination plug with a telephone plug and a low-voltage power plug installed in a common housing, and a connection mechanism that allows the plug to be inserted into an insertable combination plug outlet.

To connect the composite cord and the composite plug to each other so that the wiring state is matched in appearance and is functional.

(Means for Solving the Problems) The present invention has been completed to satisfy all of the above-mentioned problems to be solved, and its configuration will be explained below.

The plug socket housing is provided with a plug socket terminal for connecting the insulated wire core for communication and a plug socket terminal for connecting the insulated wire core for low voltage power, and a plug for connecting the insulated wire core for communication is provided in the plug socket housing. A blade terminal is provided to connect the blade terminal and the insulated wire core for low-voltage power, and the composite plug and the composite plug-in outlet are configured to be freely attachable to and detachable from each other, and the two insulated wire cores for communication and the low-voltage power This is a cord set for communication equipment, characterized in that wire cores at one end of the composite cord, each of which has an insulated wire core covered with a common jacket, are connected to the aforementioned plug blade terminals for communication and low-voltage power, respectively.

(Function) Since the present invention has the above-mentioned configuration, the insulated wire core for communication and the insulated wire core for low voltage power connected to the composite plug socket according to the present invention can be connected to multiple telephones currently in use. If installed in advance, one speakerphone can be used as a conference phone in a frequently used location by inserting the combined plug included with this invention into any of the pre-installed combined plug outlets. It is convenient because it allows you to

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 3. The telephone insulated wire core 1 is connected to the telephone outlet terminal of the composite outlet 7 which is provided with a telephone outlet terminal and a low voltage power outlet terminal, and the low voltage power outlet terminal is connected to the telephone insulated wire core 1. The insulated wire core 6 for low voltage power that has been converted into is connected.

Telephone plug blade terminal 1 is attached to the base 9 of the composite plug.
0,10' and low voltage power plug blade terminal 11,1
1' is formed.
Two telephone insulated wire cores 13, 13' and low voltage power insulated wire cores 14, 14' are collectively coated to form a composite cord 12, and the wire cores 13, 13' are used as a telephone plug blade terminal 10. , 10', the wire cores 14, 14' are connected to the plug blade terminals 11, 11' for low voltage power.

Cores 13, 13', 1 at the other end of composite cord 12
4 and 14' to the terminals of the speakerphone main body 3.

When the composite plug 8 is inserted through the windows 18, 18', 18'', 19, 19' of the composite plug outlet 7, the speakerphone can be used.

Note that when there are three or more insulated wire cores 6 of a low-voltage power supply that converts commercial 100V voltage to low voltage, it is necessary to connect the insulated wire cores to the low-voltage power supply of a composite plug outlet (not shown). Needless to say, the required number of plug-in outlet terminals should be provided, the same number of plug-in blade terminals for low-voltage power of the composite plug should be provided, and the composite cord should also be one in which they are all covered together.

Further, the number of communication insulated wire cores 13, 13' and plug blade terminals 10, 10' is not limited to two, but three or more than three are also included in the present invention.

(Effects of the invention) Since a composite cord is used that covers both a telephone insulated wire core and a low-voltage power insulated wire core, the appearance is good and the wiring condition is consistent, and the composite plug can be attached to and removed from a composite outlet. Since it can be inserted freely, the speakerphone can be easily moved to other locations.
