Abstract
The utility model discloses a charger cable and a charging device. The charging device is characterized in that the charging device comprises a charger and a charger cable; the charger cable is matched with the charger; a power supply terminal, an earth terminal, a D+ data transmission terminal and a D- data transmission terminal are included at one end of the charger cable at least; and the D+ data transmission terminal is in short circuit with the D- data transmission terminal, The utility model normally recognizes the charger device through the short circuit between the D+ data transmission terminal and the D- data transmission terminal of the charger cable.
Description
Technical field
The utility model relates to communication technical field, relates in particular to a kind of charger cable and charging device.
Background technology
Nowadays the charging device of mobile phone has become the indispensable communication tool of people, and popular cell-phone function emerges in an endless stream especially, corresponding mobile phone corollary equipment also becomes and is enriched, the standard cell phone charger of China is by standard USB line (Universal Serial Bus at present, USB), one end is a standard USB interface, and the other end is that Mini USB (micro universal serial bus interface) is connected with charger for mobile phone.In order to discern mobile phone corollary equipment and charger for mobile phone, in the prior art, charger adopts D+, D-transfer of data (hereinafter to be referred as D+, the D-) short-circuit of terminals with its interface end, and mobile phone corollary equipment commonly used is owing to need transfer of data, and D+ data transfer terminal, the D-data transfer terminal of its interface end do not have short circuit.The port of mobile phone just can short circuit judges insertion is charger or mobile phone corollary equipment by identification D+ data transfer terminal, D-data transfer terminal, yet mobile phone for the usb data cable that D+ data transfer terminal, D-data transfer terminal are provided, such RM is feasible, but a lot of at present low terminals, mobile phone producer only offers charge cable or the charger that the user has power supply terminal (VBUS) and earth terminal (GND).
In realizing process of the present utility model, the inventor finds that prior art has following shortcoming:
For the low-end mobile phone that adopts the cell-phone charging cable do not have D+ data transfer terminal, D-data transfer terminal, the mobile phone port just can't detect whether short circuit of D+ data transfer terminal, D-data transfer terminal, can't discern charger device.
The utility model content
The utility model discloses a kind of charger cable and charging device, so that charger device is normally discerned.
The utility model provides a kind of charging device, it is characterized in that, comprise charger and charger cable, described charger cable matches with described charger, at least one end of described charger cable comprises power supply terminal, earth terminal, D+ data transfer terminal and D-data transfer terminal, described D+ data transfer terminal and described D-data transfer terminal short circuit.
The utility model also provides a kind of charging device, comprise charger and cable, described cable matches with described charger, described cable comprises power supply terminal, earth terminal, D+ data transfer terminal and D-data transfer terminal at least, and described D+ data transfer terminal and described D-data transfer terminal be short circuit mutually.
Compared with prior art, the utility model embodiment has realized the normal identification of the equipment that is recharged to charger device with the described D+ terminal of charger cable and D-terminal short circuit mutually.

The corresponding setting of charger cable among the utility model embodiment with USB interface, perhaps corresponding setting with the MiniUSB interface, the cable that is the charger end can adopt USB interface or Mini USB interface, the cable of mobile phone end also can adopt USB interface commonly used at present to be connected with mobile phone, also can adopt Mini USB interface commonly used to be connected with mobile phone.
The foregoing description with D+ data transfer terminal 131 and D-data transfer terminal 132 short circuit mutually, can realize that being recharged equipment normally discerns charger device.
Fig. 3 is the structural representation that the charging device of another embodiment of the present utility model is connected with the equipment of being recharged, at least the cable 22 that comprises charger 21 and match with charger, cable 22 comprises power supply terminal 221, earth terminal 222, D+ data transfer terminal 2231 and D-data transfer terminal 2232, and D+ data transfer terminal 2231 and D-data transfer terminal 2232 be short circuit mutually.
Be recharged equipment 23 and can be mobile phone, or other equipment that need charge.
The foregoing description with D+ data transfer terminal 2231 and D-data transfer terminal 2232 short circuit mutually, can be realized normally discerning being recharged 23 pairs of chargers 21 of equipment.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
