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 built into a telephone requires a low-voltage power source in order to use the microphone and speaker. Therefore, as shown in Fig. 4, in the past, a telephone insulated wire core 1 was connected to a speakerphone 3 via a telephone connection terminal housing 2, and then to a commercial 100V power outlet 4, and the voltage was converted from AC100V to a low voltage. 5 and the insulated wire cores 6 of the converted low-voltage power supply were connected to the speakerphones.

In such a situation, the telephone insulated wire core and the low-voltage power insulated wire core are separate, making handling difficult, making the appearance messy and undesirable, and making it difficult to connect each one when moving the speakerphone. Depending on the length of the insulated wire core, it was difficult to move it.

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

To cover an insulated wire core for a telephone and an insulated wire core for low voltage power at once and use it as a composite cord without separately preparing and connecting it to a speakerphone.

To improve a connection terminal casing for a telephone, and to make the connection terminal casing equipped with two or more connection terminals for a low-voltage power supply.

The composite cord and the terminal of the connection terminal housing are connected 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 will be explained below based on the drawings.

As shown in FIG. 1, the present invention provides telephone insulated wire cores 9, 9' on the connecting terminal insulating base 8 of the connecting terminal housing 7.
metal plate terminals 10, 10' for connecting the metal plate terminals 10, 10' and metal plate terminals 12, for connecting the insulated wire cores 11, 11' for low voltage power.
12' is provided, and the insulated wire cores 9, 9' for telephone and the insulated wire cores 11, 11' for low voltage power are collectively coated to form a composite cord 13, and the wire cores 9, 9' are connected to metal plate terminals for telephone. 10 and 10', wire cores 11 and 11' are respectively connected to metal plate terminals 12 and 12' for low voltage power.

(Example) An example of the present invention will be described with reference to FIG. A cord set for communication equipment having the above configuration is prepared, and the insulated wire core 1 for telephone is connected to the metal plate terminals 10 and 10'.
Insert the voltage converter 5 that converts the commercial 100V voltage into a low voltage into the outlet 4 of the commercial 100V power supply, and connect the insulated wire core 6 of the converted low voltage power supply to the metal plate terminals 12,1.
2', and the wire core 9 at the other end of the composite cord 13,
The speakerphone can be used by connecting terminals 9', 11, and 11' to the terminals of the speakerphone body 3.

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, the same number of metal plate terminals 12, 12' are used to connect the insulated wire cores, although not shown. , 12'' are provided, and the composite cord is also made by covering them all together.

In addition, insulated wire cores 9, 9' for communication and metal terminals 10,
The number of 10' is not limited to 2 or 2, but 3 or more than 3 is also included in the present invention.

(Effects of the invention) Since a composite cord is used, in which an insulated wire core for telephones and an insulated wire core for low-voltage power are covered all at once, the appearance is good, the wiring condition is matched, and it is convenient when moving the speakerphone. be effective.
