Abstract
The invention belongs to the mobile terminal field and provides a universal serial bus USB interface. The USB interface comprises a USB interface main body. The USB interface further comprises a power source line plugging tongue with two plugging portions, a ground line plugging tongue with two plugging portions, two power source pins and two ground pins; the bottom of the power source line plugging tongue and the edge of the bottom of the ground line plugging tongue are fixed to the USB interface main body; the bottoms of the two power source pins are respectively connected with the bottom of the power source line plugging tongue; and the bottoms of the two ground pins are respectively connected with the bottom of the ground line plugging tongue. With the universal serial bus USB interface adopted, the two plugging portions of the power source line plugging tongue can be utilized to receive electric signals; current can be shunted by the two power source pins and the two ground pins; a charging loop can be formed through the ground line plugging tongue with the two plugging portions; and therefore, charging current higher than 3 amperes can be supported, and one terminal can transmit high current to the other terminal, so that the other terminal can be driven to work.
Description
Technical field
The application belongs to field of mobile terminals, particularly relates to a kind of general-purpose serial bus USB interface.
Background technology
Along with the progress in epoch, the Internet and mobile radio communication provide the function application of magnanimity.User not only can use mobile terminal to carry out tradition application, such as: use smart mobile phone to answer or call; Meanwhile, user not only can use mobile terminal to carry out web page browsing, picture transfer, game etc.
While using mobile terminal process thing, owing to using the frequency of mobile terminal to increase, the electricity of mobile terminal battery core can be consumed in a large number, thus need often charging; Due to the quickening of rhythm of life, the urgent thing that especially happens suddenly gets more and more, and user wishes to carry out large current charge to the battery core of mobile terminal.
Existing mobile terminal often adopts MICROUSB interface to charge, because this MICROUSB interface only comprises: the power line tongue with a Plug Division, the ground wire tongue with a Plug Division, the power pins connected with power line tongue and the ground pin connected with ground wire tongue, therefore, existing MICROUSB interface can only by a power path and one ground path to form the charging in a loop, thus can only the charging current of maximum support 3 amperes (A), therefore, charging rate is slow, loses time.
Summary of the invention
The object of the application is to provide a kind of general-purpose serial bus USB interface, adopts the MICROUSB interface of standard to charge, the problem that charging rate is slow to solve existing mobile terminal.
On the one hand, the general-purpose serial bus USB interface that the application provides, comprises USB interface main body; Described USB interface also comprises:
There is the power line tongue of two Plug Divisions, there is the ground wire tongue of two Plug Divisions, two power supply stitch and two ground stitch;
The bottom of described power line tongue and the bottom margin of described ground wire tongue are fixed on described USB interface main body, the bottom of two described power supply stitch all with the bottom connection of described power line tongue, the bottom of two described ground stitch all with the bottom connection of described ground wire tongue.
The beneficial effect of the application: the USB interface obtained after improving existing MICROUSB interface (socket), has the power line tongue of two Plug Divisions, have the ground wire tongue of two Plug Divisions, two power supply stitch and two ground stitch.Thus, by this USB interface, two Plug Divisions of power line tongue can be used to receive the signal of telecommunication simultaneously, by two power pins and two ground pin share current, ground wire tongue simultaneously by having two Plug Divisions forms charge circuit, and then the charging of more than 3 amperes electric currents can be supported, a mobile terminal can also be realized and big current is transferred to another mobile terminal to drive this another mobile terminal work.
Accompanying drawing explanation
Fig. 1 is the structure chart of the USB interface that the embodiment of the present application provides;
Fig. 2 is the cut-away view of the USB interface that the embodiment of the present application provides.
Embodiment
The structural representation of the general-purpose serial bus USB interface that the embodiment of the present application shown in composition graphs 1 provides, the simultaneously internal structure of the USB interface (not comprising USB interface main body 1 and grafting shell 2) shown in composition graphs 2, details are as follows:
Present embodiment discloses a kind of general-purpose serial bus USB interface, comprise USB interface main body 1; Described USB interface also comprises: the power line tongue 3 with two Plug Divisions, there is the ground wire tongue 7 of two Plug Divisions, two power supply stitch (power supply stitch 8 and power supply stitch 9) and two ground stitch (stitch 13 and ground stitch 14), to carry out large current charge by described power line tongue 3, described power supply stitch (comprising power supply stitch 8 and power supply stitch 9), described ground stitch (comprise ground stitch 13 and stitch 14) and described ground wire tongue 7;
The bottom 32 of described power line tongue 3 and the edge, bottom 72 of described ground wire tongue 7 are fixed on described USB interface main body 1, the bottom (bottom 81 of power supply stitch 8 and the bottom 91 of power supply stitch 9) of two described power supply stitch all connects with the bottom 32 of described power line tongue 3, and the bottom of two described ground stitch (the bottom 131 of stitch 13 and the bottom 141 of ground stitch 14) all connects with the bottom 72 of described ground wire tongue 7.
When carrying out large current charge (big current of such as 3A to 4A), to be connected the power supply signal to receive big current with the power line in USB plug by two Plug Divisions (Plug Division 31 and the Plug Division 33 of power line tongue 3) of power line tongue 3; Meanwhile, two Plug Divisions (Plug Division 71 and the Plug Division 73 of ground wire tongue 7) of ground wire tongue 7 are connected the charge circuit to form big current with ground wire.Increase a Plug Division in order on the power line tongue that provides in existing USB interface, increase the contact area bottom power line tongue; And then while power line tongue can have two Plug Divisions, two power pins can also be connect.Correspondingly, increase a Plug Division in order on the ground wire tongue that provides in existing USB interface, increase the contact area bottom ground wire tongue; And then while ground wire tongue can have two Plug Divisions, two ground pins can also be connect.And then the ground wire tongue 7 after the power line tongue 3 after bottom area increases and bottom area increase, large twice of charging current that the charging current that can support is supported than existing MICROUSB interface or more, improves the maximum current that can bear effectively.
Correspondingly, because two power pins connect with the bottom 32 of described power line tongue 3 respectively, can two-way be divided to transmit the power supply signal received from power line, to charge to the battery core of mobile terminal by these two power supply stitch (power supply stitch 8 and power supply stitch 9).Simultaneously, because two ground pins are also connect with the bottom 72 of described ground wire tongue 7 respectively, when the negative pole of the battery core of mobile terminal is after oversampling circuit and two ground pins form electric pathway, the large current charge loop to battery core charging can be formed.Like this, the USB interface that the present embodiment provides, forms two charge circuits by two power pins and two ground pins, can reduce power loss, reduce heating, avoid burning charging circuit.
