Abstract
The utility model provides a USB adaptor with a DB9 serial port and a DB25 parallel port, which solves the problems of required converters for connection between the prior various digital equipment and the host computers as well as varied circuits and troublesome splice. The structure of the USB adaptor comprises a casing provided with a circuit board inside; a USB connecting wire connected with a host computer is arranged on one side of the casing, a DB9 pin serial port capable of being connected with a piece of digital equipment is arranged on a second side surface of the casing, screw holes used for fixing the digital equipment are arranged on both sides of the serial port correspondingly, a DB25 pin parallel port capable of being connected with another piece of digital equipment is arranged on the converse side surface corresponding to the second side surface, and other screw holes used for fixing the digital equipment are arranged on both sides of the parallel port correspondingly. The two pieces of digital equipment can be connected with the host computer via the USB adaptor without waiting, the reaction is prompt, the compatibility is high, and neither data lines nor converters are required to be carried, therefore, the utility model has the advantages of simplicity, practicality and portability.
Description
Technical field
The utility model relates to a kind of adapter, relates to a kind of band serial ports that computer is connected with multiple ancillary equipment and USB adapter of parallel port be convenient to specifically.
Background technology
Along with social progress and expanding economy, the popularity rate of computer is more and more higher, utilizing many ancillary equipment of main frame connection all to use in a lot of occasions obtains, these ancillary equipment are finished transfer of data or exchange with computer by the USB connecting line, and some computers can be less for the interface that ancillary equipment connects, it is very inconvenient then to seem when many ancillary equipment need use, on the other hand, the ancillary equipment connector of each manufacturer is in size, all different in shape, or even the special-purpose USB connecting line of employing, can't be connected with computer anywhere or anytime, this has brought a lot of troubles and inconvenience to us.
Summary of the invention
In order to solve the existing in prior technology deficiency, it is a kind of easy to use, environmental and durable that the utility model provides, compatible strong, and have the USB adapter of DB9 serial port and DB25 parallel port.
For achieving the above object, the utility model by the following technical solutions:
A kind of USB adapter that has DB9 serial port and DB25 parallel port, comprise that an inside is provided with the housing of circuit board, housing one side is provided with the USB connecting line that is connected with main frame, its second side is provided with the serial ports that can join with digital equipment, be provided with the parallel port that can join with digital equipment corresponding to the face of tossing about of second side, described serial port setting is the DB9 pin, and corresponding being provided with in the serial ports both sides is used for the screw that fixes with digital equipment, described parallel port is set to the DB25 pin, and corresponding being provided with in the both sides, parallel port is used for the screw that fixes with digital equipment.
Owing to adopted above structure, the utlity model has following distinguishing feature and beneficial effect:
One: highly versatile, can between USB and the special-purpose connecting line plug of multiple digital product, connect, do not need to carry a plurality of connecting lines or transducer;
Two: simple in structure, with low cost, volume is light and handy, has effectively solved the space and the use problem of going out to carry, and can not puzzle one's brains because of the difference of socket or plug;
Three: each interface all is independently to link to each other with main frame, can not interact among the work, raises the efficiency greatly.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is a structure vertical view of the present utility model;
