JP3089545U - Charging plug - Google Patents

Abstract

(57) [Summary] An object of the present invention is to enable charging of an electronic device having a USB connector terminal from a power socket provided in a room or the like. A charging plug having a power connection terminal has a US plug.
Charging plug with B socket 3.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a charging plug that enables charging of an electronic device having a universal serial bus (USB) connector terminal from a power socket.

[0002]

[Prior art]

 A conventional charging plug has a power connector terminal at one end, a lead wire directly connected to the other end, and a connector terminal for connecting to a specific electronic device such as a mobile phone at the end of the lead wire. It is commercially available.

[0003]

[Problems to be solved by the invention]

 However, electronic devices that can use such a charging plug are limited to those that can be connected to a connector terminal provided at the end of a lead wire.

On the other hand, many recent personal computer devices are provided with a USB socket, and accordingly, many electronic devices having a USB connector terminal are commercially available. Therefore, there is a drawback that an electronic device having a USB connector terminal cannot be charged from a power socket provided indoors.

Accordingly, an object of the present invention is to propose a charging plug that enables charging of an electronic device having a USB connector terminal from a power socket provided indoors.

[0006]

[Means for Solving the Problems]

 This invention proposes a charging plug provided with a power supply connection terminal and a USB socket in view of the above-mentioned circumstances.

[0007]

[Embodiment of the invention]

 In other words, in the present invention, the power supply terminal of the charging plug is connected to a power supply socket provided in a room or the like, and the USB connector terminal of the electronic device is further connected to the USB socket of the charging plug to charge the electronic device. However, since the charging plug is provided with a USB socket, it is possible to charge an electronic device having a USB connector terminal from the power socket.

In this case, the electronic device and the charging plug may be connected via a lead wire provided with a USB connector at one end and a connector of a mobile device such as a mobile phone or a PDA at the other end. This enables various types of charging such as mobile devices such as mobile phones and PDAs.

[0009] By using a charger provided with a voltage setting circuit of 90V to 240V inside as a charger used in the present invention, it can be applied to commercial power sources in the world including Japan, the United States and Europe. be able to.

[0010] In addition, by mounting an overcharge prevention circuit on the charger, it can be used without worrying about the remaining battery level of a mobile phone or the like.

[0011]

【Example】

 Hereinafter, the present invention will be described in detail based on the illustrated embodiment. Reference numeral 1 denotes a charging plug constituting the present invention. The charging plug 1 has a connection terminal 2 of a power socket, and a side portion thereof has a USB. A socket 3 is provided.

In the circuit of the charging plug 1, between the input terminal of the connection terminal 2 and the output terminal of the USB socket 3, there are provided an overcharge prevention circuit 4 and a voltage setting circuit 5 of 90 V to 240 V.

On the other hand, reference numeral 6 denotes a lead wire used in the present invention. One end of the lead wire 6 is provided with a USB connector 7 and the other end is provided with a connector 8 of a portable telephone.

In the above configuration, when charging a mobile phone or the like using the power socket, the connection terminal 2 of the charger 1 is connected to the power socket, and the USB socket 3 of the charger 1 is connected. To the USB connector 7 provided at one end of the lead wire 6, and to the connector 8 provided at the other end of the lead wire 6 to connect the portable telephone.

In this embodiment, since the overcharge prevention circuit 4 is provided in the charger 1, it is possible to charge the portable telephone without worrying about the remaining battery level.

Further, in this embodiment, since the connector 8 is adapted to be compatible with various types of mobile phones, there is a high possibility that the connector 8 can be used as it is even when the mobile phone is replaced.

In this embodiment, charging of a mobile phone has been described. However, by changing the connector 8, the mobile phone can be used for charging a mobile device such as a PDA other than the mobile phone.

[0018]

[Effect of the invention]

 In short, according to the present invention, it is possible to charge an electronic device having a USB connector terminal using a power socket installed in a room or the like.
