Abstract

The utility model relates to an integral USB to 9 pin serial converter for the computer field, which comprises a USBA male interface, a converter circuit board, a 9-pin serial port, a 9-pin serial port, a USBA male interface and a converter circuit entity, all welded on the same one circuit board in turn. The utility model has simple structure without matching USB line or USBA male to USBB male extension line required, small appearance, and is convenient to carry.

Description

Integral type USB nine-pinned serial port converter

Technical field

The utility model relates to the integral type USB nine-pinned serial port converter that computer realm is used.

Background technology

Trendy notebook computer is not equipped with low-level interface at present, as nine needles serial port and LPT, only dispose some advanced interface, as USB interface, 1394 interfaces, but also have many equipment to use old-fashioned interface and the old-fashioned universal serial bus of this class of serial ports now, as mobile phone, palm PC, industrial control equipment etc., so if the USB interface that will use serial equipment just must dispose converts serial ports to, and the nine needles serial port that thumping majority equipment all is to use; In addition, general desktop computer all only is equipped with one or two nine needles serial ports, and USB interface just has four to six, if the serial equipment that uses is too many, will convert USB interface to serial ports, to satisfy the demand of equipment.In addition, also have an important use, because USB interface has hot plug, the characteristics that plug and play and transmission speed are fast if use USB nine-pinned serial port converter, just in a disguised form become old-fashioned serial equipment USB socket equipment, just have the advantage of USB interface.Yet computer can only use USBA public access mouth.Existing product, that USBA public access mouth and circuit board is not welded together, shown in accompanying

drawing

2,3,, cause whole length longer because this class converter must be with USB line or USB extended line, volume is bigger, is inconvenient to carry; In addition, install this class converter after, the connecting line between each equipment of computing machine is long, brings great inconvenience to use, and line many can give mixed and disorderly sensation.

Summary of the invention

The purpose of this utility model is to provide a kind of simple and reasonable, convenient and practical integral type USB nine-pinned serial port converter, to overcome weak point of the prior art.

Integral type USB nine-pinned serial port converter by this purpose design comprises USBA interface, converter circuit plate, nine needles serial port.USB public access mouth, converter circuit plate and nine needles serial port are welded on the same circuit board successively.

Can reach user's purpose in the place that USB interface need be converted to nine needles serial port as long as the utility model pegged graft up.The utility model is simple and reasonable, and profile is small and exquisite, is convenient for carrying, and can or not seem mixed and disorderly between each circuit after the grafting.
