Embodiment Construction
[0015] see figure 1 and figure 2 , the one-to-many serial connection device of the present invention includes a connection card 10 and a connection line 20;
[0016] The connection card 10 is provided with a serial signal transceiving control module 11 and at least one Mini DisplayPort connector 12. The serial signal transceiving control module 11 has at least two sets of serial signal input and output pins of DB9 connector specifications. 13. The number of contacts of the Mini DisplayPort connector 12 is as follows: image 3 As shown, there are 20 contacts P1-P20, and the serial signal input and output pins 13 of the two DB9 connector sockets are electrically connected one-to-one with the Mini DisplayPort connector 12 contacts. In this embodiment, the serial signal The transceiver control module 11 has a total of four sets of serial signal input and output pins 13 of DB9 socket specification, and another Mini DisplayPort socket 12' is further set on the connection card 10...

The invention relates to a multi-serial port connecting device which comprises a connecting card and a connecting line. The connecting card is provided with a tandem signal transmitting-receiving control module and at least one Mini DisplayPort connecting seat. The tandem signal transmitting-receiving control module is provided with at least two groups of tandem signal input / output (I / O) pin with the specification of DB9 connecting seat. The two groups of tandem signal input / output pin with the specification of DB9 are respectively connected with twenty connecting points of the Mini DisplayPort connecting seat. The connecting line comprises a plug member, at least two socket members with the specification of DB9 and a lead set. The plug member is provided with a Mini DisplayPort plug, and the plug is respectively electrically connected with the two socket members with the specification of DB9 with the lead set to provide connection for two electronic devices with a DB9 connector. Thus, the space occupied by the connecting seat on the connecting card can be reduced.
Description
technical field [0001] The invention relates to a connection device, especially a multi-serial port connection device and a connection card thereof. Background technique [0002] The serial port refers to the serial communication connection port, mostly refers to the COM (Component Object Model) interface, which is a variety of serial signal transmission interfaces, such as RS232, RS422 and RS485, etc. According to the number of contacts, it is roughly divided into two specifications: D-type 9-pin serial port (DB9) and D-type 25-pin serial port (DB25). However, with the design trend of computer miniaturization, such as Figure 6 As shown, most computer manufacturers tend to adopt USB connector 72 (supporting serial signal transmission) or Mini DisplayPort connector 73 (supporting video and audio signal transmission), etc., which are smaller in size than DB9 connector 71, and because the USB connector It is also a communication interface for serial signals, so the probabilit...
