With reference to Fig. 3 and Fig. 4, Fig. 3 is pcb board and USB annexation schematic diagram in the utility model embodiment one USB device, Fig. 4 is the generalized section of the utility model embodiment one USB device, wherein, for clarity sake, among the figure metal shell and the decomposition of plastic cement structural member of USB head are come, be with a USB of the prior art difference, there are not golden finger and terminal on the USB head, USB 31 is made up of plastic cement structural member 41 and metal shell 42, metal shell 42 can be connected with the draw-in groove 44 of plastic cement structural member 41 by buckle 43, and the draw-in groove 23 that is carved with an end of golden finger on the buckle 45 that USB 31 and pcb board 21 can be by USB plastic cement structural member 41 parts and the pcb board 21 is connected.In order to prevent static, the metal shell 43 of USB 31 can comprise ground strip 46, and described ground strip 46 is welded on the pcb board 21.
Owing to there is not terminal, therefore the USB head is shorter than the length of USB head in the prior art in the present embodiment, with reference to Fig. 1, the USB head length degree of standard is 21.00mm in the prior art, remove terminal length, the length of the USB head of the utility model embodiment is 18.8mm, and the utility model can also adopt a plastic cement structural member to be connected technology with a metal shell, with the contraction in length of described USB head to 15.8mm, wherein 12mm is connected with various USB interface equipment for exposing pcb board part, and pcb board is connected by button bit with the plastic cement structural member of USB head and the method for removing terminal reaches the purpose of shortening USB head.
From embodiment one as can be seen, because golden finger is engraved on the pcb board, the USB head does not need special terminal to be connected with pcb board, therefore can so that with the All Ranges beyond USB the contact area can the cloth components and parts, can improve the usable floor area of pcb board, and then can make length or the width that shortens USB device, and reduce the size of USB device, make things convenient for the user to carry.
And, owing to adopt a plastic cement structural member to be connected technology with a metal shell, can shorten the length of USB head, and pcb board can be socketed on the pcb board, avoided being connected with pcb board, be used for the cloth components and parts, therefore can improve the usable floor area of pcb board thereby can vacate more pcb board by terminal, shorten the length of USB device, be convenient to the user and carry.
Embodiment two, be with the difference of embodiment one, by screw the USB head is fixed on the pcb board, with reference to Fig. 5 and Fig. 6, wherein, Fig. 5 is the pcb board schematic diagram in the utility model embodiment two USB device, Fig. 6 is pcb board and USB the annexation schematic diagram in the utility model embodiment two USB device, is provided with screw 51 by the pcb board among Fig. 5 21, by screw 61 PCB 31 is fixed on the pcb board 21.
The USB head in the present embodiment and the difference of existing USB head are, there are not terminal and golden finger, with reference to Fig. 7, be the USB header structure schematic diagram in the utility model embodiment two USB device, form by metal shell 71 and inner plastic cement structural member 72, screw 73 and screw fit are used for the USB head is fixed on pcb board.The USB head is socketed in the end that pcb board has golden finger by plastic cement structural member 72, carries out the signal transmission by golden finger.And be engraved in golden finger on the pcb board by the element conductive on inner cabling and the pcb board.
Owing to there is not terminal, therefore the USB head is shorter than the length of USB head in the prior art in the present embodiment, with reference to Fig. 1, the USB head length degree of standard is 21.00mm in the prior art, remove terminal length, the length of the USB head of the utility model embodiment is 18.8mm, and the utility model can also adopt a plastic cement structural member to be connected technology with a metal shell, with the contraction in length of described USB head to 15.5mm, wherein 12mm is connected with various USB interface equipment for exposing the pcb board part, and pcb board and USB head reach the purpose that shortens the USB head by the method for screw and removal terminal.
From embodiment two as can be seen, because golden finger is engraved on the pcb board, the USB head does not need special terminal to be connected with pcb board, therefore can so that with the All Ranges beyond USB the contact area can the cloth components and parts, can improve the usable floor area of pcb board, and then can make length or the width that shortens USB device, and reduce the size of USB device, make things convenient for the user to carry.
And, owing to adopt a plastic cement structural member to be connected technology with a metal shell, can shorten the length of USB head, and pcb board can be socketed on the pcb board, avoided being connected with pcb board, be used for the cloth components and parts, therefore can improve the usable floor area of pcb board thereby can vacate more pcb board by terminal, shorten the length of USB device, be convenient to the user and carry.
In summary, because the USB head does not need terminal to be connected with pcb board, but adopt the USB headgear to be connected on the frame mode of an end that is carved with golden finger on the described PCB, the USB head can be shortened to below the 18.8mm, and, cooperate the metal shell of USB head to adopt different technology to connect with the plastic cement structural member, can further shorten the USB head, but, in order to meet the prior USB standard, the length of described USB head is greater than 12mm.
In addition; the USB device that is provided for the utility model embodiment; because there is the golden finger part on the plastic cement structural member protection pcb board USB head inside; and whole external connecting branch has the metal shell protection; can avoid inner stitch or part bending or damage; therefore no matter the USB head plugs, and inner body all is not easy impaired.
For fear of the USB device wrong plug, the USB interface corresponding with the USB head can also adopt the fool proof design, the opposite USB head of direction can not socket in, direction positive and negative user be easy to and can feel out.
In addition, the USB head of the utility model embodiment USB device can also prevent static with corresponding USB socket: because the structure of USB head, when the USB head is inserted the USB seat, the metal shell of USB head outside can touch metal corresponding in the USB socket earlier partly, and four of plug inside contacts just can touch the USB seat afterwards.Metal shell can be connected to the place of system, provides the path that static can be discharged, and avoids causing damage because of static by electronic component.
More than USB device that the utility model embodiment is provided be described in detail, used specific case herein principle of the present utility model and execution mode set forth, the explanation of above embodiment just is used for helping to understand the utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
