Abstract
Provided is computer USB connection interfaces, comprising four USB connection interfaces. Each connection interface is respectively provided with a positive voltage end, a grounding end, and at least a signal transmitting-receiving end. The computer USB connection interfaces also comprise a connection wire. The four positive voltage ends are coupled with each other by the connection wire. The four grounding ends are coupled with each other by the connection wire. The four signal transmitting-receiving ends are coupled with each other by the connection wire. The computer USB connection interfaces also comprise a power module which is coupled between the positive voltage end of the first USB connection interface and the positive voltage end of the second USB connection interface through the connection wire. The power module is coupled between the positive voltage end of the first USB connection interface and the positive voltage end of the third USB connection interface through the connection wire. The power module is coupled between the positive voltage end of the first USB connection interface and the positive voltage end of the fourth USB connection interface through the connection wire.
Description
Technical field
The utility model relates to a kind of connector, especially relates to a kind of computer USB connecting interface that can expand circuit bearing capacity.
Background technology
Along with scientific and technological development and progress, notebook computer and portable digital device are more and more widely used and popularize, the said equipment reading data is except Adoption Network is downloaded, also need external equipment, such as externally-connected optical drive, hard disk etc., in general mostly adopt USB interface to connect, but because USB interface only can provide the drive current of 500mA, so need external power supply, this set has caused the inconvenience using, especially in travelling or going on business on the way.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of computer USB connecting interface that can increase USB drive current, and the technical scheme of employing is as follows:
A kind of computer USB connecting interface, comprise four USB connecting interfaces, each connecting interface has respectively a positive voltage terminal, an earth terminal and at least one signal transmitting and receiving end, computer USB connecting interface also comprises a connecting line, aforementioned four positive voltage terminals couple mutually through connecting line, aforementioned four grounded end couples mutually through connecting line, aforementioned four signal transmitting and receiving ends couple mutually through connecting line, computer USB connecting interface also comprises a power module, be coupled between the positive voltage terminal of a USB connecting interface and the positive voltage terminal of the 2nd USB connecting interface by connecting line, power module is also coupled between the positive voltage terminal of a USB connecting interface and the positive voltage terminal of the 3rd USB connecting interface by connecting line simultaneously, power module is also coupled between the positive voltage terminal of a USB connecting interface and the positive voltage terminal of the 4th USB connecting interface by connecting line simultaneously.
Preferably: a USB connecting interface, the 2nd USB connecting interface and the 3rd USB connecting interface are male joint, and the 4th USB connecting interface is female joint.
Adopt said structure, can effectively increase the drive signal current of USB interface of computer, be convenient to portable set in the wild or journey use.
Accompanying drawing explanation
Fig. 1 is a kind of computer USB of the utility model connecting interface schematic diagram.
Fig. 2 is a kind of computer USB of the utility model connecting interface internal wiring schematic diagram.
Embodiment
As shown in Figure 1, 2:
A kind of computer USB connecting interface, computer USB connecting interface comprises USB connecting interface 110, 120, 130, 140 and connecting line 160, the first, second and the 3rd USB connecting interface 110, 120, 130 is male joint, and the 4th USB connecting interface 140 is female joint, each USB connecting interface 110, 120, 130, 140 have respectively a positive voltage terminal 122, 112, 132, 142 1 earth terminals 118, 128, 138, 148 and at least one signal transmitting and receiving end 114, 116, 124, 126, 134, 136, 144, 146, aforementioned, four positive voltage terminals 112, 122, 132, 142 couple mutually through connecting line 160, aforementioned four grounded end 118, 128, 138, 148 couple mutually through connecting line 160, aforementioned eight signal terminals 114, 116, 124, 126, 134, 136, 144, 146 couple mutually through connecting line 160, computer USB connecting interface also comprises a power module (not shown), be coupled between the positive voltage terminal 112 of a USB connecting interface 110 and the positive voltage terminal 122 of the 2nd USB connecting interface 120 by connecting line 160, power module is also coupled between the positive voltage terminal 112 of a USB connecting interface 110 and the positive voltage terminal 132 of the 3rd USB connecting interface 130 by connecting line 160 simultaneously, and power module is also coupled between the positive voltage terminal 112 of a USB connecting interface 110 and the positive voltage terminal 142 of the 4th USB connecting interface 140 by connecting line 160 simultaneously.Due to mutually coupling between power supply terminal, can make drive current expansion be twice above even more, and the signal transmission of USB circuit is not affected.
The above, be only embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection range of utility model.
