Description

  The present invention relates to a power strip for connecting an outlet and a plug of an electrical device.

  An outlet serving as a power outlet is usually fixed to a wall, and the number of plug outlets is limited to a few. Therefore, a power strip is used to increase the number of plug insertion ports according to the number of electrical devices to be used or to supply power to electrical devices located away from the outlet.

In this regard, Patent Documents 1, 2, and 3 propose a power strip provided with a plurality of load plug insertion ports so that a plurality of loads can be used.
Patent Documents 4 and 5 propose a power strip provided with a switch for switching an energization state of a load plug insertion port.
Patent Documents 6, 7, 8, and 9 propose a power strip in which a switch for switching the energization state of a load plug insertion port is provided at hand.
Further, Patent Document 10 proposes a power strip in which a plurality of load plug insertion ports are prepared and the energization state of the plurality of load plug insertion ports can be switched at hand. .

  The plug sockets PS14 and PS15 are also connected in parallel. The plug sockets PS14 and PS15 supply power to the load as long as power is supplied from the outlet regardless of the operation of the socket switch SW4. It has become.

  The pilot lamps PL11, PL12, and PL13 are turned on or off according to the energized state of the corresponding plug sockets PS11, PS12, and PS13, respectively. At the same time, the pilot lamps PL21, PL22, PL23, and PL24 are turned on or off according to the energization state of the corresponding plug sockets PS11, PS12, PS13, and PS21.

  The pilot lamps PL11, PL12, PL13 can be activated or stopped according to the operation of the lamp switch LSW1, and the pilot lamps PL21, PL22, PL23, PL24 can be activated or stopped according to the operation of the lamp switch LSW5. Yes.

  The pilot lamp PL4 indicates an energized state with respect to the plug sockets PS11, PL12, PS13, PS21, and is turned on or off according to the operation of the socket switch SW4.

  In addition to these elements, elements normally incorporated in the power strip 1 such as a capacitor and a varistor as a surge absorbing element can be appropriately incorporated in this electric circuit.

  According to the power tap 1 according to the present embodiment, a plurality of plug insertion ports 11a to 15a and 21a for loads such as electronic devices are provided, which is convenient when a large load is used. Further, since the socket body 10 and the switch body 20 are provided as separate bodies, and the connection cable 40 for connecting them has a certain length, the socket switches SW21 to SW23 can be used even at locations away from the plug insertion ports 11a to 13a. , SW4 is operated, and the energization states of the plug insertion ports 11a to 13a can be switched individually or collectively. Therefore, the load plug does not get in the way when the switch is operated, and the cable connected to the plug does not get in the way and is easy to use.

Next, a power strip 5 according to another embodiment of the present invention will be described with reference to FIG.
Similar to the power tap 1, the power tap 5 according to the present embodiment includes a socket body 50, a switch body 60, a power plug 70, and a connection cable 80.

Here, the plug sockets PS51 to PS55, the plug insertion ports 51a to 55a, and the lamp switch LSW6 included in the socket body 50 are respectively plug plugs PS11 to PS15, the plug insertion ports 11a to 15a, and the lamp switch LSW1 included in the socket body 10. And has the same configuration.

The pilot lamps PL are configured by a characteristic number and arrangement so that the pilot lamps PL can be easily and individually identified.

That is, the pilot lamps PL51, PL52, and PL53 correspond to the plug sockets PS51, PS52, and PS53, respectively, but the numbers in Braille notation indicate “1”, “2”, and “3”, respectively. One pilot lamp, a pair of pilot lamps arranged side by side in the width direction of the socket body 50, and a pair of pilot lamps arranged side by side in the length direction of the socket body 50 are configured. On the other hand, the pilot lamps PL61, PL62, and PL63 are also arranged side by side in the width direction of one pilot lamp and the switch body 60 so that the numbers in braille indicate “1”, “2”, and “3”, respectively. A pair of pilot lamps provided and a pair of pilot lamps provided side by side in the length direction of the switch body 60 are configured. Further, the pilot lamp PL64 is constituted by three pilot lamps collected so as to form the vertices of a right-angled isosceles triangle, as indicated by “4” in braille notation.
In this example, the braille notation of numbers is used. However, the present invention is not limited to this, and braille notation using hiragana may be used. Ordinary Arabic numerals may be used, and various notation means can be used as long as each pilot lamp PL and socket switch SW can be individually identified.
Moreover, Braille notation etc. may be given to the upper surface of socket switch SW61-SW64, and the number of Braille notation may be formed by the protrusion using the convex part of LED which comprises each pilot lamp PL. This allows people with disabilities to know their numbers by touching them with their fingers and can be switched on and off safely. Such protrusions can also be created when the main body is formed.

The pilot lamp PL51 and the pilot lamp PL61 indicating the energized state of the plug socket PS51 are configured by pilot lamps having the same number and arrangement, and any of the plug sockets PS in which the pilot lamp PL51 indicates the energized state is used. (In this case, the plug socket PS51) can be identified at a glance.
Similarly, the pilot lamps PL62 and the pilot lamps PL63 are plug sockets PS52 and PS53 in which the pilot lamps PL62 and the pilot lamps PL63 indicate the energized state by grasping the pilot lamps PL52 and PL53 having the same number and arrangement. Can be identified at a glance.
