Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a transformer box that allows a vehicle electrical appliance to be used with a household power source.

[Conventional technology]

Recently, various car accessories have been developed that can be inserted into the socket of a cigarette lighter installed in a vehicle. Furthermore, some electric appliances such as radio cassettes can be operated by plugging a cord into a car's cigarette lighter socket, and can even be used with a household power source by changing the cord.

[Problem to be solved]

Various electrical appliances that can be used in cars by plugging them into cigarette lighter sockets cannot be used directly on household power sources.

Therefore, this idea was developed with the aim of providing a transformer box that allows various electrical appliances that are plugged into a cigarette lighter socket in a car to be used with a household power source.

[Means for solving problems]

In order to achieve the above-mentioned purpose, this invention provides a transformer for using automotive electrical appliances with household power, and connects to this transformer to provide a socket similar to the socket of a vehicle cigarette lighter. It has been established.

[Effect]

This idea uses a transformer to change the voltage of the household power supply to the same level as the voltage output to the vehicle cigarette lighter, and since it has the same outlet as the vehicle cigarette lighter, it can be used with various vehicle electrical appliances. If you plug it into the outlet as is, you can use it using a household power source.

〔Example〕

Preferred embodiments of this invention will be described below with reference to the drawings.

In FIG. 1, the member designated by the reference numeral 1 is an electrical appliance for a vehicle, and the drawing shows a lighting fixture. The base end of this vehicle electric appliance 1 is equipped with a plug 1A similar to a vehicle cigarette lighter. The transformer box 2 according to this invention is equipped with a transformer 3 (see Figs. 5 and 6) for using the household power supply for vehicle electric appliances, and is connected to the transformer 3 to supply a vehicle cigarette. A socket 4 similar to a lighter socket is provided. Further, reference numeral 5 is a cord connected to a household power source, and this cord 5 is connected to the transformer 3.
It is connected to. Further, the transformer box 2 is provided with a switch 6 and an indicator light (LED) 7 for indicating the energized state when the switch 6 is in the on state. Further, reference numeral 8 is a heat radiation hole. A clamp through hole 9 is formed in the bottom of the transformer box 2. Furthermore, as shown in FIG. 4, hook holes 10, 10 for wall hanging are formed in the bottom surface of the transformer box 2. In FIG. 4, reference numeral 11 indicates a hole for a fuse holder. A fuse holder 12 (see FIG. 6) is attached to this fuse holder hole 11. This fuse holder 12 is provided with a fuse 13,
After changing the voltage with transformer 3, this fuse 1
3 to the insertion port 4. In FIG. 5, a socket portion 4A forming the insertion port 4 is shown. In addition, a clamp 1 is inserted into the previous clamp through hole 9.
4 is inserted, and table 1 is inserted as shown in Figure 5.
The transformer box 2 can be fixed on the 5.

In the illustrated embodiment, the insertion port 4 is formed on the upper surface of the transformer box 2 near one end, but it goes without saying that the location where the insertion port 4 is formed is not limited to the location shown in the drawings. In addition, although a lighting fixture is illustrated as the vehicle electrical appliance 1, not only the lighting fixture but also a vehicle vacuum cleaner, a vehicle shaver, etc. can be used with the transformer box 2 using a household power source. be.

〔effect〕

As explained above, according to this invention, a transformer is provided for using a household power supply to electrical appliances for vehicles, and a socket similar to the socket of a vehicle cigarette lighter is connected to the transformer. With this, it is now possible to use all electrical appliances for vehicles that use cigarette lighters as a power source with household power.
