DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conversion connector, and more particularly, to a conversion connector used for connecting a device having a universal interface terminal to a portable telephone device.

[0002]

2. Description of the Related Art A universal serial bus (Univer) is a type of serial interface standard for computer equipment.
sal Serial Bus: USB). This USB is
The specifications were released in February 1996 by Compaq (trademark: COMPAQ), Microsoft (trademark: Microsoft), and the like. The USB is used to unify the interface used to connect relatively low-speed peripheral devices such as a keyboard, a mouse input device, a modem, and a printer device to a personal computer. And came to be able to use cables. In recent years, a large number of personal computers and peripheral devices equipped with the USB-compatible terminal have been sold.

In recent years, portable telephones can be connected to a computer via a cable to exchange data. Specifically, as data communication between a portable telephone and a computer, data relating to an address book, a ring tone, and the like are exchanged. At this time, the portable telephone is USB-connected to the computer via a dedicated cable 100 as shown in FIG. 3, and performs data communication. That is, the cable 100 includes a USB connector 102 connected to a computer 101,
Mobile phone connector 10 connected to mobile phone 103
4 and a conversion circuit 105 for converting a signal based on the USB standard into a signal based on the mobile phone standard.

[0004]

The above-mentioned portable telephone is equipped with a secondary battery such as a lithium ion battery. The secondary battery is charged by connecting a portable telephone and a power supply via a charging cable. In addition, as a cable used when charging the portable telephone, there is a cable 106 for connecting the computer 101 and the portable telephone 103 as shown in FIGS. The cable 106 has a USB connector 107 connected to the computer 101 and a mobile phone connector 108 connected to the mobile phone 103. That is, when the cable 106 is used, the portable telephone 103 is charged via the computer.

As described above, when a portable telephone is connected to another device, it is necessary to use a dedicated cable for each application, which is complicated and uneconomical. .

Accordingly, the present invention has been made in view of such a conventional situation, and connects between a portable telephone device and a computer device, and performs data transfer between the portable telephone device and the computer device. An object is to provide a conversion connector capable of performing communication and charging.

[0007]

A conversion connector according to the present invention, which has achieved the above-mentioned object, comprises a first terminal conforming to the universal serial bus (USB) standard and a portable telephone for transmitting a signal conforming to the universal serial bus standard. A conversion circuit for converting into a signal based on the standard, a second terminal based on the portable telephone standard, and connecting the first terminal and the second terminal via the conversion circuit, or A switch for selecting whether to directly connect the terminal and the second terminal.

[0008] The conversion connector according to the present invention configured as described above is connected to a computer device with a first terminal and connected to a portable telephone device with a second terminal. In this state, in the conversion connector, a switch can be used to select whether to connect the computer device and the portable telephone device via the conversion circuit or to connect directly. When the computer device and the portable telephone device are connected via a conversion circuit, the conversion connector is used for performing data communication. On the other hand, when the computer device and the portable telephone device are directly connected, the conversion connector is used to charge and discharge a secondary battery of the portable telephone device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a conversion connector according to the present invention will be described below in detail with reference to the drawings.

As shown in FIG. 1, a conversion connector 1 according to the present embodiment is a universal serial bus (Universa serial bus).
l Serial Bus: A USB terminal 2 conforming to the USB standard and a signal conforming to the USB standard are converted into a signal conforming to the portable telephone standard, and conversely, a signal conforming to the portable telephone standard is conformed to the USB standard Conversion circuit 3 for converting to a signal
And a mobile phone terminal 4 based on a mobile phone standard, and a USB
A switch 5 is provided for selecting whether the terminal 2 and the mobile phone terminal 4 are connected via the conversion circuit 3 or directly connected.

Therefore, in the conversion connector 1, by switching the switch 5, the USB terminal 2 and the mobile phone terminal 4 are connected via the conversion circuit 3, or the USB terminal 2 and the mobile phone terminal 4 are connected. Direct connection can be selected as appropriate.

The conversion connector 1 configured as above is
As shown in FIG. 2, it is connected to the computer 6 via the USB terminal 2 and to the mobile phone 7 via the mobile phone terminal 4.

When the conversion connector 1 is used, data communication between the computer 6 and the portable telephone 7 and charging / discharging of the secondary battery mounted on the portable telephone 7 can be performed.

When performing data communication between the computer 6 and the portable telephone 7, the switch 5 is turned on, for example. By turning on the switch 5 in this manner, the USB terminal 2 and the mobile phone terminal 4 are connected to the conversion circuit 3.
Will be connected via the. Therefore, by using the conversion connector 1, the US 6
Data communication between the computer 6 and the portable telephone 7 can be performed using a signal conforming to the B standard and a signal conforming to the portable telephone device standard.

When charging / discharging the secondary battery mounted on the portable telephone 7, the switch 5 is turned off, for example. By turning off the switch 5 in this way, the USB terminal 2 and the mobile phone terminal 4 are directly connected. Then, a secondary battery such as a lithium ion battery mounted on the portable telephone 7 can be charged and discharged via the computer 6. Specifically, when the computer 6 is connected to a power supply, the mobile phone 7 is connected to the power supply via the computer 6 and thus can be charged. In the case of a computer 6 having a power supply device such as a notebook type, the mobile phone 7
It can be charged from a power supply device mounted on the computer 6.

In other words, if the conversion connector 1 is used, the portable telephone 7 can be charged and discharged using the computer 7 without using a special charger and a charging connector. At the same time, if this conversion connector 1 is used, data communication between the computer 7 and the portable telephone 7 can be performed. As described above, if the conversion connector 1 is used, data communication and charging / discharging can be performed without using a complicated plurality of connectors.

The conversion connector 1 preferably has an overcharge / overcurrent protection circuit for preventing overcharge and overcurrent of the secondary battery attached to the portable telephone device. It is preferable that the overcharge / overcurrent protection circuit is provided, for example, between the mobile phone terminal 4 and the switch 5 and is connected when the switch 5 is turned off. By arranging the overcharge / overcurrent protection circuit in this way, it is possible to reliably prevent overcharge and overcurrent when charging the above-described secondary battery, and to ensure safety measures. .

[0018]

As described above, in the conversion connector according to the present invention, the first terminal and the second terminal are connected via the conversion circuit, or the first terminal and the second terminal are connected to each other. Since a switch for selecting whether to directly connect to the terminal is provided, data communication and charging / discharging can be performed. Therefore, by connecting the portable telephone and the computer with the conversion connector, data communication and charging / discharging can be performed only with the conversion connector. Therefore, according to this conversion connector, the connection between the portable telephone and the computer becomes simple and economical.
