Description

  The present invention relates to an outlet that integrates a power supply terminal and a communication terminal to improve efficiency mainly for electrical appliances (including digital network home appliances) having a communication terminal function.

In general, most appliances eventually operate with a DC power source.
Nevertheless, the power supply to the appliance is AC100V.

  In order to secure a DC power supply, the manufacturing company is equipped with an AC / DC power supply unit for each product to cope with it.

  Furthermore, the AC / DC power supply unit in the product is a technically big problem with respect to the reduction in size and weight of the product.

Next, with regard to the wiring method in the electrical appliance having the communication function, another communication cable is required separately from the power cable, and two wires are always required.

  In order to facilitate replacement of the power fuse, an overcurrent protection circuit 4 is disposed on the front surface of the main body 1 to protect the circuit inside the main body 1 when the current from the outlet terminal portions 12a and 27a is short-circuited. .

  Jumper terminals 7 and 22 are provided on the front surface of the outlet 1 so that it can be easily converted as an outlet for the fuel cell 13, which is expected as a new power supply. That is, the jumper terminals 7 and 22 are means for selecting a power source to be connected to the outlet terminal unit from among a plurality of power sources.

  Collective switch circuits 8 and 23 are arranged on the front surface of the main body 1 so that switching between the LAN, FTTH 16, telephone line, and ISDN 17 can be easily achieved. That is, the collective switch circuit 8 is a means for selecting a communication line connected to the communication terminals 12c to 12f from the plurality of communication lines. Similarly, the collective switch circuit 23 is means for selecting a communication line to be connected to the communication terminals 27c to 27f from the plurality of communication lines.

  Filter circuits 6 and 21 are incorporated in the main body 1 so as to be compatible with power line communication.

  As shown in FIG. 1, the outlet terminal portions 12 and 27 output + 24V to 12a and 12b is grounded. That is, the outlet terminal portion is a DC power supply terminal.

  Next, 12c and 12d of the communication line 1 are designed for 4W transmission, and 12e and 12f of the communication line 2 are designed for 2W transmission / reception and 4W reception.

The input terminals 3 and 19 are arranged in two rows on the top of the main body 1 as shown in FIG.
In the attachment cable 38 illustrated in FIG. 6, the cable plug 12 and the attachments 33 and 34 are detachable, and in the attachments 33 and 34, an electric appliance with a communication terminal function connected to the main body 1. Is provided with a voltage conversion circuit for solving the difference in DC voltage value.

  Further, the communication terminal 36 and the DC plug 37 suitable for the connected electrical appliance with the communication function are attached to the end of the cable to achieve connection consistency. That is, the attachment cable 38 eliminates the difference in the shape of the communication terminal between the electrical appliance with the communication terminal function connected to the main body 1.

  In the future, when the voltage value of the DC power supply is unified, the attachment cable may be a connection cable composed only of the outlet terminal portion 12, and the connection can be facilitated and the product cost can be reduced.

  As shown in FIG. 1, the main body 1 is provided with a direct current power supply device 5 that converts alternating current into direct current.
