Description
Technical field
The invention relates to a kind of jockey, espespecially a kind of many serial port connectors and Connection Card thereof.
Background technology
Serial ports refers to serial communication connector, refer to COM (Component Object Model) interface more, for existing multiple tandem signal transmission interface, as conventional interface specifications 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.But, along with the designer trends of computer miniaturization, as shown in Figure 6, mostly manufacturer computer tendency adopts size compared to the less USB Connection Block 72 of DB9 Connection Block 71 (supporting tandem signal transmission) or Mini DisplayPort Connection Block 73 (supporting video-audio signal transmission) etc., and because USB connector is the communication interface that is similarly tandem signal, therefore now and the Future Computer probability of classifying DB9 or DB25 as standard interface relatively low, and face at last the destiny being eliminated.
Because the specification of DB9 is popularized for many years, be also common on the electronic installation of industrial automation and business automation, and those electronic installations can or be managed using computer as control use conventionally, and communicate with each other through the specification of DB9; Therefore no longer include DB9 Connection Block as computer, certainly will cause in the future to those electronic installations control or management on produce inconvenience greatly, historical facts or anecdotes has must be to the improvement of many serial port connectors.
Summary of the invention
The technological deficiency taking up room because above-mentioned Connection Card arranges plural DB9 serial port Connection Block, main purpose of the present invention is to propose a kind of many serial port connectors and Connection Card thereof.
Wanting to reach the technical way that above-mentioned purpose uses is to make this one-to-many serial port connector include:
One Connection Card, be provided with a tandem signal receiving/transmission control module and at least one Mini DisplayPort Connection Block, this tandem signal receiving/transmission control module has the tandem signal import and export pin position of at least two group DB9 Connection Block specifications, this Mini DisplayPort Connection Block comprises 20 contacts, again, the tandem signal import and export pin position of this two DB9 Connection Block specification is electrically connected one to one with this Mini DisplayPort Connection Block contact;
One connecting line, include socket piece and at least one wire group of a plug piece, at least two DB9 specifications, this plug piece is provided with at least one Mini DisplayPort plug, and be inserted in this Mini DisplayPort plug on the Mini DisplayPort Connection Block of this Connection Card, the contact of the contact of Mini DisplayPort plug and the contact of this Mini DisplayPort Connection Block is connected, and this wire group will be electrically connected to respectively the socket piece of this two DB9 specification to contact that should two tandem signal import and export pin positions in this Mini DisplayPort plug.
Because Mini DisplayPort Connection Block has 20 contacts, its number of connections is enough to two groups of tandem signal import and export pin position input tandem signals that are used for to tandem signal receiving/transmission control module for two DB9 Connection Blocks, and the size of Mini DisplayPort Connection Block approximately only has 1/2nd of DB9 Connection Block size, therefore the present invention is able to, in Connection Card, the Mini DisplayPort Connection Block of a size much smaller than a DB9 Connection Block size is set, seeing through connecting line for the electronic installation that two DB9 specifications are provided connects, dwindle the space that Connection Block occupies, significantly reduce Connection Block and occupy the space of host computer, on host computer or notebook computer for compactization.
