Abstract
The utility model provides a kind of Serial Port Line, the USB interface comprising cable, the DB9 interface be connected with this cable one end and be connected with this cable other end, the little USB interface of panel space is taken compared with DB9 connector or RJ45 connector by arranging, in actual applications, the area of device panel can be saved, while reducing product cost, be conducive to the miniaturization of product.
Description
Technical field
The utility model relates to communication equipment field, particularly relates to a kind of Serial Port Line.
Background technology
Serial line interface computer, telecommunications, Industry Control, etc. the communications field have and use widely, even become standard configuration in certain fields.Serial line interface is mainly used for the location of equipment debugging and failure problems.
No matter serial line interface is use DB9 (9 needle serial port) connector or use RJ45 connector, and volume is all very large.Conventional taking on panel of DB9 connector is of a size of 30.9mm*12.5mm, and conventional taking on panel of RJ45 connector is of a size of 16.6mm*13.5mm.And panel space is normally very valuable, the serial line interface of these 2 kinds of connectors often takies a lot of space of panel, causes panel to need to do more, cause the cost of product high, and volume is large.
Utility model content
The utility model object is to provide a kind of Serial Port Line, and being intended to solve serial line interface existing serial line interface, to take panel space many, cause cost high and bulky problem.
The utility model provides a kind of Serial Port Line, the USB interface comprising cable, the DB9 interface be connected with this cable one end and be connected with this cable other end.
Further, described USB interface is USB Type-A interface, USB Type-B interface, Mini USBType-A interface, Mini USB Type-B interface, Micro USB Type-A interface, Micro USB Type-B interface or USB Type-C interface.
Further, described USB interface is male joint.
Further, described DB9 interface is male joint.
Further, the signal ground pin of described USB interface connects the signal ground pin of described DB9 interface, and the data of described USB interface send pin and data receiver pin and send pin with the data receiver pin of described DB9 interface and data respectively and be connected.
Further, the metal shell of USB interface is connected by mesh shields metal wire with the metal shell of described DB9 interface.
Above-mentioned Serial Port Line takies the little USB interface of panel space by arranging compared with DB9 connector or RJ45 connector, in actual applications, can save the area of device panel, is conducive to the miniaturization of product while reducing product cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of Serial Port Line in the utility model preferred embodiment;
Fig. 2 is the equivalent circuit diagram of Serial Port Line shown in Fig. 1.
Embodiment
In order to make the technical problems to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Serial Port Line 100 in the utility model preferred embodiment, the usb 1 30 comprising cable 110, the DB9 interface 120 be connected with this cable 110 one end and be connected with this cable 110 other end.
In the present embodiment, the usb 1 30 of Serial Port Line 100 is male joint, and described DB9 interface 120 is male joint.In other embodiments, the usb 1 30 of Serial Port Line 100, DB9 interface 120 can be maternal interface.
Further, described usb 1 30 is USB Type-A interface, USB Type-B interface, Mini USB Type-A interface, Mini USB Type-B interface, Micro USB Type-A interface, MicroUSB Type-B interface or USB Type-C interface.
The pin of USB connector (male, for Micro USB Type-B interface) has two kinds of definition modes, as shown in the table:
| Pin | Serial ports definition 1 | Serial ports definition 2 |
| 1 | Unsettled | Unsettled |
| 2 | TXD (transmission data) | RXD (reception data) |
| 3 | RXD (reception data) | TXD (transmission data) |
| 4 | Unsettled | Unsettled |
| 5 | GND (signal ground) | GND (signal ground) |
According to upper table, composition graphs 2, the signal ground pin GND of usb 1 30 meets the signal ground pin GND of described DB9 interface 120, and the data of described usb 1 30 send pin D+ and data receiver pin D-and send pin TXD with the data receiver pin RXD of described DB9 interface 120 and data respectively and be connected; Or D+ sends pin as data receiver pin, D-as data, so RXD then sends pin as data, and TXD is then as data receiver pin.The benefits of these two kinds definition are: even if this interface is mistaken as when being USB functional interface and is connected to USB device, also can not cause any infringement to this USB.Other usb 1 30 and DB9 interface 120 pin then unsettled.
Further, the metal shell (being defined as PGND pin) of usb 1 30 is connected by mesh shields metal wire PGND with the metal shell (being defined as PGND pin) of described DB9 interface 120.And, for the cable 110 not having shielding requirements, this root line can be deleted.
Above-mentioned Serial Port Line 100 takies the little usb 1 of panel space 30 by arranging compared with DB9 connector or RJ45 connector, in actual applications, can save the area of device panel, is conducive to the miniaturization of product while reducing product cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
