Description
Technical field
The invention relates to a kind of jockey, refer to a kind of many serial ports jockey and Connection Card thereof especially.
Background technology
Serial ports is meant the serial communication connector; Refer to COM (Component Object Model) interface more; Be existing multiple tandem signal transmission interface; Like interface specification commonly used such as RS232, RS422 and RS485, and existing serial ports Connection Block is roughly divided into D type 9 needle serial ports (DB9) and two kinds of specifications of D type 25 needle serial ports (DB25) according to number of contacts.Yet; Designer trends along with the computer miniaturization; As shown in Figure 6, mostly the manufacturer computers tendency adopts sizes compared to the littler USB Connection Block 72 (supporting the transmission of tandem signal) of DB9 Connection Block 71 or Mini DisplayPort Connection Block 73 (supporting audio-visual signal transmission) or the like, and because USB connector is the communication interface that is similarly the tandem signal; So now and following computer the probability that DB9 or DB25 classify standard interface as is low relatively, and face the destiny that is eliminated at last.
Because the specification of DB9 is popularized for many years, also be common on the electronic installation of industrial automation and business automation, and those electronic installations usually can be with computer as control or management usefulness, and the specification that sees through DB9 is communicated with each other; Be with, no longer include the DB9 Connection Block like computer, certainly will cause in the future those electronic installations are produced inconvenience greatly in control or management, historical facts or anecdotes has must be to the improvement of many serial ports jockey.
Summary of the invention
The technological deficiency that takes up room because above-mentioned Connection Card is provided with plural DB9 serial port Connection Block, main purpose of the present invention are to propose a kind of many serial ports jockey and Connection Card thereof.
Desiring to reach the employed major technique means of above-mentioned purpose is to make this one-to-many serial ports jockey include:
One Connection Card; Be provided with a tandem signal receiving/transmission control die set and at least one Mini DisplayPort Connection Block; This tandem signal receiving/transmission control die set has the tandem signal of at least two group DB9 Connection Block specifications and exports into the pin position; This Mini DisplayPort Connection Block comprises 20 contacts, and again, the tandem signal of this two DB9 Connection Block specification is exported into the pin position and is electrically connected one to one with this Mini DisplayPort Connection Block contact;
One connecting line; The socket piece and at least one lead group that include a plug spare, at least two DB9 specifications; This plug spare is provided with at least one Mini DisplayPort plug; And be inserted on the Mini DisplayPort Connection Block of this Connection Card with this Mini DisplayPort plug; The contact that makes Mini DisplayPort plug is connected with the contact of the contact of this Mini DisplayPort Connection Block, this lead group with in this Mini DisplayPort plug to exporting the socket piece that is electrically connected to this two DB9 specification into the contact of pin position respectively by two tandem signals.
Because of Mini DisplayPort Connection Block has 20 contacts; Its number of connections is enough to supply two DB9 Connection Blocks to be used for two groups of tandem signals of tandem signal receiving/transmission control die set are exported into pin position input tandem signal; And the size of Mini DisplayPort Connection Block approximately has only 1/2nd of DB9 Connection Block size; So the present invention is able in Connection Card the Mini DisplayPort Connection Block of a size much smaller than a DB9 Connection Block size is set; Confession provides the electronic installation of two DB9 specifications to see through the connecting line connection; Dwindled the space that Connection Block occupies, significantly reduced the space that Connection Block occupies host computer, with host computer or the notebook computer that is used for compactization.
