Abstract

A novel microcomputer communication and printing connection port is a rectangular plastic-sealed signal transfer box 1, wherein the A end of the rectangular plastic-sealed signal transfer box is a DS25P pin socket which is matched with a printer port of a computer, and the other end of the rectangular plastic-sealed signal transfer box, which is correspondingly connected with a 25-core flat cable 2, is a DB25P hole socket B end which is a signal wiring port of the printer. One end of the 11-core communication cable 3 is welded on the A-end socket, and the other end of the 11-core communication cable is led out through the C port and then welded on the D port of the DS25P pin-type socket. The utility model discloses can realize the intercommunication between two computers, realize data sharing, file transmission, equipment sharing (like CD-ROM, floppy disk drive, hard disk etc.) to can share a printer.

Description

Microcomputer communication is held concurrently and is printed connecting port

The utility model belongs to the microcomputer communication print interface circuit technical field of holding concurrently.

At present, finding has only microcomputer communication interface or printer shared device on the market.The microcomputer communication interface can only be used for the information transmission between two or many microcomputers, and the interface circuit complexity; And the printer shared device only is used for many shared printers of microcomputer, it has mechanical type and electronic type two big classes, its principle all is that signal is switched between the various computing machine, and exists shortcomings such as electronic type printer shared device costs an arm and a leg, mechanical type printer shared device use inconvenience.

The purpose of this utility model just provides the double connecting port of printing of a kind of novel microcomputer communication, it can realize the mutual communication of two intercomputers, realize data sharing, file transfer, equipment shared (as CD-ROM drive, floppy disk, hard disk etc.), and can share a printer.

Accompanying drawing 1 is held concurrently for the utility model microcomputer communication and is printed the synoptic diagram of connecting port.

Accompanying drawing 2 is the socket synoptic diagram of A port in the utility model, B port, D port.

Referring to accompanying drawing 1, the utility model is achieved in that design one square shape envelope Signal transfer box 1, specification 4 * 5cm², 1.5 centimetres of thickness. The A end is D type 25 core pin type sockets (model is DS25P), it and meter The printer port of calculation machine matches, and connected mode is solder type. Connect with 25 core flat cables 2 are corresponding with it The other end is the B end, and the B end is D type 25 core pass sockets (model is DB25P), and the mode of connection is pressure line type, It is the signal connection jaws of printer. The C port is the outlet of communication cable 3, and is used for the connection of fixed telecommunication cable The place. 11 core communication cables, 3 one ends are welded on the DS25PA end socket, and the other end is welded on D end model and is On the D type 25 core pin type sockets of DS25P. The length of communication cable 3 is generally 3～4 meters. D end socket is used for Be connected the connection of computer communication mouth.

Referring to accompanying drawing 2, A end socket and B hold the pin of socket number to connect one to one with 25 core

flat cables

2 or 25 of standard hard drive signal wires.The 2nd, 3,4,5,6,10,11,12,13,15,25 pins of A end pin type socket hold the 15th, 13,12,10,11,5,6,4,3,2,25 pins of pin type socket to connect one to one with D respectively with 11 core communication cables 3.

Can utilize the utility model to realize between microcomputer that point-to-point communication reaches between microcomputer the method for resource sharing and has multiplely, modal have: the communication program InterLnk, the intersvr that 1) utilize MS-DOS6.X to provide; 2) the Drivemap driver redirection function that utilizes PCtools9.0 to provide; 3) the laplink for DOS/windows program of utilizing Traveling to provide.Wherein the 2nd kind of method has distinctive characteristic, can realize memory-resident, carries out communication on the backstage and can articulate cd cd-ROM etc. under the DOS environment.

Major advantage of the present utility model is: the security to equipment is good: do not have mechanical change action, need not plug cable and socket; Invest little: the mechanical hook-up that does not increase any electronic equipment and need to regulate; Easy to manufacture: as only to make a plastic packaging interconnecting device and 11 core shielded cables; Function is strong: solved intercomputer communication problem and made some expensive equipment (as CD drive) can share use easily, file, data transmission have solved and have relied on traditional " parasite net " (to copy files on the floppy disk, between computing machine, carry out information switching method) vehicular cumbersome approaches, efficient height, easy to use is only imported number order on computers and can be dealt with problems.
