Description

A kind of Micro USB and standard USB interface adapter

Technical field

The utility model relates to USB interface, particularly a kind of interface adapter that Micro USB interface female seat is converted into standard USB interface male seat.

Background technology

USB (English: Universal Serial Bus, be called for short USB) and be a serial ports bus-bar standard that connects external device (ED), use on computers extensively.An external bus standard, for being connected and communication of standard computer and external equipment.

At present, standard USB interface is a kind of conventional pc interface, and he only has 4 lines, two signals of two power supplys, therefore signal is serial transmission, usb interface is also referred to as serial port, and the speed of usb2.0 can reach 480Mbps.Can meet various industry and civilian needs.Output voltage and the electric current of USB interface are: in fact+5V 500mA has error, and maximum can not exceed namely 4.8-5.2V of +/-0.2V.4 lines of usb interface are generally to distribute so below, both sides black line and red line are respectively GND and VCC, middle green line and white line are respectively data+ and data-, wherein, in square metal tube, four lines are successively set on a pcb board, middle data+ and data-line are shorter compared with the VCC of both sides and GND line, like this, and when USB mouth accesses, first connect with the mains, then just connect signal, when transfering to, holding wire first disengages, then just power line disengages, and has realized like this heat and has dialled slotting.

Micro USB is a portable version of standard, generally be arranged on the small intelligent equipment such as mobile phone, for communicating by letter with other relevant apparatus, at present, Micro USB interface is a D type little compared with standard USB interface, at present, on the larger smart machine such as PC, dispose standard USB interface, Micro USB interface is generally arranged on the small intelligent equipment such as mobile phone, if having the smart machine that the mobile device (as mobile phone USB flash disk etc.) of Micro USB male seat interface will be relatively large with PC etc. communicates by letter, need to there is Micro USB female seat to turn adapter or the patchcord of standard USB male seat, generally a patchcord at present on the market, one is a standard USB interface male seat, other end is Micro USB interface female seat, a middle line couples together.Such USB interface male seat all needs the five metals that forms a circle around and in Micro USB interface female seat, and cost is higher, and volume is too large, and outward appearance is more not attractive in appearance.

Utility model content

The purpose of this utility model is to overcome current Micro USB female seat to turn the adapter of standard USB male seat or the higher deficiency of the complicated cost of Wiring technology, provide a kind of Micro USB female seat being comprised of a pcb board and integrated shell to turn standard USB male adapter, in this adapter, USB interface male seat does not need five metals shell around and in Micro USB interface female seat.

The technical solution of the utility model is: a kind of Micro USB and standard USB interface adapter, comprise shell, also comprise a pcb board, one described of pcb board one head breadth is narrow, the wide width of is identical with standard USB interface, and the narrow width of is identical with Micro USB interface; On described pcb board, on a face of wide head, be provided with standard USB interface wire, on a face of narrow head, be provided with Micro USB wire, described standard USB interface wire and the Micro USB wire both sides in pcb board respectively; Described standard USB interface wire is electrically connected with corresponding Micro USB wire.

The two-stage step shape that described shell is formed in one, is provided with the preformed hole identical with Micro USB interface size at the back side of the two stage steps of shell, described preformed hole is through hole, the other end of through hole shell one, two to stage interface on.

Described pcb board is arranged on described shell, on a wide fixing described shell subordinate table top of described pcb board, form the male seat of standard USB interface, described pcb board narrow one forming Micro USB interface female seat in shell preformed hole together with shell preformed hole.

The utility model provides a kind of Micro USB and standard USB interface adapter, this adapter have one can be inserted into computer etc. there is the male seat of standard USB interface and one can be by the Micro USB interface female seat that there is Micro USB interface and insert, and in USB interface male seat and Micro USB interface female seat, all do not need metal framework, reduced the cost of Micro USB and standard USB interface adapter.

Below in conjunction with specific embodiment, the utility model is described in more detail.

Embodiment

Embodiment 1, the present embodiment is a kind of by Micro USB interface female seat and standard USB interface male seat adapter, be generally used for the mobile device that only has Micro USB interface is linked into and is only had on the smart machines such as the computer of standard USB interface, we know, at present, the mobile device of the mobile device interfaces such as a lot of equipment and mobile phone, IPAD only has Micro USB interface, mobile phone or IPAD etc. have the female seat of Micro USB interface, and the mobile device supporting with it has the male seat of Micro USB interface.At present, PC etc. only have standard USB interface, can access a lot of electronic equipments with USB interface such as USB flash disk, but can not access the mobile USB equipment of the male seat of only having Micro USB interface, therefore, the present embodiment just provides so a kind of adapter, the standard USB interface male seat of this adapter is pulled into the USB interface of PC, then only has the USB interface male seat of the mobile USB equipment of the male seat of Micro USB interface just can be inserted in the Micro USB interface female seat of adapter.
