Abstract

The utility model relates to a pocket USB access insert which comprises plug metal conductive contact pieces at both ends and a plastic base plate. The pocket USB access insert is characterized in that the whole access insert is integral; the middle part of the plastic base plate is thick; and the plug metal conductive contact pieces at both ends are respectively inlaid on the plastic base plate with two thin ends, and directly and correspondingly connected in the plastic base plate. The width of the plug part is consistent with that of the USB plug of the prior art, and the thickness is corresponding to that of the conductive tab and the lower part of the USB plug of the prior art. As the whole access insert is integral, the access insert is extremely thin and small to a great extent, the volume is greatly reduced, the thickness is one third of the original thickness, and the access insert is convenient to carry. As the two USB plug metal conductive contacts are directly and correspondingly connected in the plastic base plate, the data transmission is stable; the structure of the shift connecting wire of the present USB plug is greatly simplified, and the manufacture cost and difficulty are reduced.

Description

Pocket USB refutes and patches sheet

Technical field

The utility model relates to a kind of plug of refuting that connects computer and peripheral digital devices.

Background technology

Along with the arrival of cybertimes, as the standard that connects computer and ancillary equipment, USB interface is simple to operate with it, the advantage of plug and play is widely used in computer realm more and more.At present, comprise that nearly all digital devices such as MP3, MP4, mobile phone, camera have all disposed USB interface, with being connected of convenient realization and computer.But, also all adopted the minibus USB interface gradually along with the miniaturization gradually of these digital devices.Simultaneously, because the needs of the modern life, carry-on digital device also is on the increase, and the data bus connection of these equipment, charger, earphone etc. have also occupied the more space with oneself of people gradually, in case it is all the more so to go on business, have increased many burdens to people.This has proposed to adopt unified standard and the constantly requirement of miniaturization just for the usb data interface.

Conventional USB refutes in succession, and line is made of two USB plug and line.Each USB plug comprises plug metallic conduction contact chip, contact chip plastic substrate, substrate metal shell, plastic cement fixed block and connecting line, and volume is thicker relatively, bigger.For the ease of carrying, occurred simplifying the USB that falls line afterwards again and refuted plug, but size and the thickness of refuting plug have also kept conventional size.

Summary of the invention

The utility model is in order to overcome above-mentioned deficiency, provides a kind of ultra-thin and pocket USB that contact performance is more good to refute and patches sheet, and volume dwindles greatly, more convenient carrying.

Realize that the technical scheme that above purpose adopts is: refute and patch sheet and form by two ends plug metallic conduction contact chip and plastic substrate, it is characterized in that wholely refuting that to patch sheet as a whole, the plastic substrate mid portion is thicker slightly, the metallic conduction contact chip of the USB plug at two ends is embedded in respectively on the thin plastic substrate in two ends, and the metallic conduction contact chip of the USB plug at two ends is in inner directly corresponding linking to each other of plastic substrate; The width of USB plug part and the USB plug of prior art are consistent, the conducting strip of the USB plug of thickness and prior art and suitable with the gross thickness of lower part, the jack sliding fit of plug and corresponding USB socket.

The beneficial effects of the utility model are: whole refuting patches sheet as one, farthest makes it ultra-thin, extra small, dwindled volume greatly, and thickness only is original 1/3rd, conveniently carries; Because two USB plug metallic conduction contact chip makes transfer of data more stable in inner directly corresponding linking to each other of plastic substrate; Simplify present USB plug greatly and refuted the structure of line in succession, reduced manufacturing cost and manufacture difficulty.

Description of drawings

Fig. 1 is an example structure schematic diagram of the present utility model.

Concrete execution mode

As shown in Figure 1, the main purpose of refuting the structural design that patches sheet of embodiment of the present utility model is to simplify substrate metal shell, plastic cement fixed block and connecting line, thereby the USB that is reduced into an one refutes and patches sheet.Refute and patch sheet and form by the metallic conduction contact chip and the plastic substrate of the USB plug at two ends, wholely refute that to patch sheet as a whole, plastic substrate 3 mid portions are thicker slightly, the USB plug 7 at two ends, 6 metallic conduction contact chip 1,5 are embedded in the thin plastic substrate 2 in two ends respectively, on 4, the USB plug 7 at two ends, 6 metallic conduction contact chip 1,5 in 3 inner directly corresponding linking to each other of plastic substrate, USB plug 7,6 the width and the USB plug of prior art are consistent, the metallic conduction contact chip of the USB plug of thickness and prior art and suitable with the gross thickness of lower part, jack sliding fit with corresponding USB socket, whole refuting patches sheet thickness and is about 3mm, for original 1/3rd, length is 40-50mm.

Claims

1, a kind of pocket USB refutes and patches sheet, form by two ends plug metallic conduction contact chip and plastic substrate, it is characterized in that: wholely refute that to patch sheet as a whole, plastic substrate (3) mid portion is thicker slightly, the metallic conduction contact chip (1,5) of the USB plug at two ends (7,6) is embedded in respectively on the thin plastic substrate (2,4) in two ends, and the metallic conduction contact chip (1,5) of the USB plug at two ends (7,6) is in inner directly corresponding linking to each other of plastic substrate (3); The width of USB plug (7,6) and the USB plug of prior art are consistent, the conducting strip of the USB plug of thickness and prior art and suitable with the gross thickness of lower part, the jack sliding fit of plug (7,6) and corresponding USB socket.
