Description

  The present invention relates to a table tap for supplying power to an electrical product.

  Conventionally, in a table tap having a plurality of outlets, all outlets are generally independent. In a special table tap such as a PC, there is a product that switches on all other outlets when a device connected to a specific outlet is turned on. (Patent Document 1, Patent Document 2)

  However, in recent electric devices, especially large computer systems that use a combination of multiple electric devices, and business systems, etc., there is a possibility that devices and built-in devices may be destroyed if the power-on / off sequence is incorrect. .

  In completed home appliances, computer systems, etc., a safety circuit is mounted on the power supply unit, and it can be operated without being aware of the order in which the power is turned on. There are things that will not power off.

  In an audio device such as karaoke, a microphone, microphone preamplifier, commander, power amplifier, speaker, etc. are connected, and it is necessary to turn on the power in the order of microphone → microphone preamplifier → commander → power amplifier. The reverse is necessary, that is, power amplifier → commander → microphone preamplifier → microphone. If this order is mistaken, there is a risk that a large power supply noise is generated or, in the worst case, a device such as a speaker is destroyed. Even if there are still two or three devices, it does not matter so much. However, as the number of devices increases, the procedure for turning on / off the power becomes complicated, causing confusion for workers and causing an accident in which the order of turning on / off is wrong.

  Patent Document 1 makes it easy to turn on / off an electric product having many accessory devices, and prevents the power switch from being forgotten to be turned off. One main outlet to which voltage is constantly applied, a relay that closes a contact when a current flows through the main outlet, and a contact that opens when a current is cut off, and a plurality of interlocks wired through the contact portion of the relay Consists of an outlet.

  In Patent Document 2, when a child electronic device that is a peripheral device of a parent electronic device is used at the same time, the power supply of the child device is linked with the power switch of the parent electronic device with a simple structure. Provided is a power strip that can be turned on and can prevent forgetting to turn off a child electronic device. When power is supplied to a parent electronic device having a service connector and a peripheral peripheral electronic device, a first power plug inserted into a power outlet provided on a wall or the like, and the plug and the power cord A tap body having one or more connector groups for inserting a power plug of a connected electrical device as a child, and provided between the power plug and the tap body, and the power supply to the tap body is turned on. , A switch for turning off, a second power plug inserted into the service connector of the parent electronic device, and detecting that the service connector is in an active state via the second power plug This is a power strip constituted by switch control means for controlling ON / OFF of the switch.

  In Patent Document 3, when the switch knob is set to the first position, only the first switch is turned on and only the ventilation fan is driven. On the other hand, when the switch knob is set to the second position, the first switch and the second switch are turned on, the ventilation fan is driven, and the illumination is turned on. When the switch knob is returned from the first position or the second position to the neutral position, the second switch is immediately turned off, but the first switch is turned off after a predetermined time has elapsed due to the action of the delay mechanism. Therefore, although the illumination is turned off immediately, the ventilation fan is stopped after being driven for a predetermined time, can be easily operated, can meet the demand for energy saving, and can be sufficiently ventilated.

  Patent document 1 and patent document 2 are outlets having a plurality of outlets for both companies. Although the main outlet is connected, the other outlet is connected by a relay when the main outlet is turned on. Since the outlet is cut, the disconnection order is reversed.

  Patent Document 3 is found in bathrooms of hotels and condominiums. The power is turned on in the order of ventilation fans → lighting, and when the lights are turned off, the ventilation fans are cut off with a delay mechanism after the lighting is turned off. However, the present invention is limited to fixed devices such as lighting and ventilation fans, and is slightly different from the object of the present invention in which a plurality of devices selected by the user are turned on and off in turn.

  In view of the above problems, claim 1 of the present invention provides a table tap having a plurality of outlets provided with a switch on the table tap, and in a specific order for each step of the switch. The interlocking table tap is characterized in that an interval is provided at each position so that the power can be turned on and off and each step does not pass without stopping.

It is a figure of the table tap of the Example of this invention. It is an enlarged view at the time of switch OFF of the rotary dial of the table tap of the Example of this invention. It is an enlarged view at the time of switch A: ON of the rotary dial of the table tap of the Example of this invention. It is an enlarged view at the time of switch A + B: ON of the rotary dial of the table tap of the Example of this invention. It is an enlarged view at the time of switch A + B + C: ON of the rotary dial of the table tap of the Example of this invention. It is an enlarged view at the time of switch A + B + C + D: ON of the rotary dial of the table tap of the Example of this invention. An example of the stopper of the rotary dial of the table tap of the Example of this invention. 1 shows an example of the structure of a rotary dial according to an embodiment of the present invention. Example 2 of the structure of the rotary dial of the Example of this invention. It is a figure of the table tap of the other Example of this invention. An example of the stopper of the table tap of the other Example of this invention. An example 1 of the structure of the slide switch of the other Example of this invention. Example 2 of the structure of the slide switch of the other Example of this invention.

In the table tap as shown in FIG. 1, there are a plurality of outlets and a rotary switch capable of selecting the outlets, and the switches are now in the OFF position, and all outlets are OFF. (Fig. 2) In addition, the rotary switch can be turned on and off with a specific outlet combination in a fixed order for each step of the switch, so that each step does not stop and does not pass through each position. physical interval a is provided, in particular rotated along the groove of such guides Uei as in FIG. 7, for example, a stopper is provided by Oite crank structures at each position, the switch can not pass through the stopping position nonstop It has become.

  Now, when the rotary switch is turned to the right and the position becomes A: ON, the rotation stops and only the outlet A is energized. (Figure 3)

  Next, when the rotary switch is further turned to the right, it stops at the position of A + B: ON. At this time, in addition to outlet A, outlet B is turned ON. (Fig. 4)

  When the rotary switch is further turned, it stops at the position of A + B + C: ON, and in addition to the outlets A and B, the outlet C is turned on. (Figure 5)

When the rotary switch is further turned, it stops at the position of A + B + C + D: ON, and in addition to outlets A, B, C, the outlet D is turned on. (Fig. 6)

In the case of cutting, it is cut in turn by turning in the same direction as a one-way dial.
Alternatively, the power may be turned off in the reverse order in the order of FIG. 6 → FIG. 5 → FIG. 4 → FIG. 3 → FIG.

  The rotary dial rotates according to the guideline as shown in FIG. 7 and is movable according to the scale position as shown in FIGS. 8 and 9 and always stops at each scale position. : Pass through ON and make a mechanism that A + B cannot turn ON.

  In the embodiment, the rotary rotary switch has been described, but the shape of the switch is not limited to this, and a linear slide switch as shown in FIG. 10 can provide the same effect. Also in this case, the slide switch moves in the groove of the guide way as shown in FIG. 11, and a crank mechanism as a stopper is arranged at each stop position, so that the switch does not pass at a stretch as shown in FIGS. It is effective to have a mechanism like this.

  According to the present invention, it is possible to simplify the handling of a device having a complicated power-on procedure and a power-off procedure regardless of the device to be connected, and prevent a situation in which the device or device is broken due to a power-on mistake.
