Abstract
The utility model discloses a general type SEL relay communication connector, it contains: be located the standard USB interface of connector one end, be located the connector other end with USB interface connection's modularization interface, this modularization interface contain a RS232 interface and a EIA485 interface. Its advantage is: its one end is equipped with the USB interface, conveniently inserts computer commonly used, and the other end is equipped with RS232 interface and EIA485 interface respectively to make things convenient for the staff to carry and use.
Description
Technical field
This utility model relates to technical field of electronic communication, is specifically related to a kind of universal SEL relay communications connectors.
Background technology
The PC relay that SEL company of the U.S. produces has wide application in power system, and main application model includes the models such as SEL351, SEL551, SEL387.SEL series relay mainly employs RS232 serial ports, two kinds of ports of EIA485 serial ports carry out communication, carry out needing to use Special-purpose connecting line to be attached with relay by corresponding port respectively when equipment debugging, maintenance, and then use SEL stipulations etc. to carry out related work.Owing to relay relevant device debugging efforts generally is on-the-spot mobile operation, carry many different types of connecting lines the most inconvenient, and easily take line when real work by mistake and cause affecting work efficiency.Meanwhile, Novel laptop is the most no longer equipped with RS232 serial ports, and USB can only be used to turn Serial Port Line, and this makes work on the spot need more carry a USB and turn serial port patch cord again, increases work on the spot complexity and difficulty further.It is therefore desirable to a kind of portable general type SEL relay communications connectors of design, SEL relay field adjustable, maintenance is facilitated to use.
Utility model content
The purpose of this utility model is to provide a kind of universal SEL relay communications connectors, and its one end is provided with USB interface, and convenient insertion commonly uses computer, and the other end is respectively equipped with RS232 interface and EIA485 interface, to facilitate staff to carry and to use.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
A kind of universal SEL relay communications connectors, is characterized in that, comprise:
It is positioned at the standard USB interface of adapter one end；
Being positioned at the modular interface being connected with described USB interface of the adapter other end, this modular interface comprises a RS232 interface and an EIA485 interface.
Above-mentioned universal SEL relay communications connectors, wherein:
Described RS232 interface and EIA485 interface lay respectively at the both sides of described modular interface.
Above-mentioned universal SEL relay communications connectors, wherein, described modular interface enclosed inside has:
USB RS 232 chip, the USB interface described in the connection of its one end, the RS232 interface described in the connection of its other end；
RS232 turns RS422 chip, and its one end connects the other end of described USB RS 232 chip, the EIA485 interface described in the connection of its other end.
Above-mentioned universal SEL relay communications connectors, wherein:
Described RS232 interface and EIA485 interface all use standard 9 needle serial port male form.
This utility model compared with prior art has the advantage that its one end is provided with USB interface, and convenient insertion commonly uses computer, and the other end is respectively equipped with RS232 interface and EIA485 interface, to facilitate staff to carry and to use.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is the chip connection figure in this utility model；
Fig. 3 is the stitch definition table of RS232 interface and EIA485 interface in embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, this utility model is further elaborated.
As shown in Figure 1, 2；A kind of universal SEL relay communications connectors, it comprises: be positioned at the standard USB interface 1 of adapter one end；Being positioned at the modular interface being connected with described usb 1 of the adapter other end, this modular interface comprises a RS232 interface 2 and an EIA485 interface 3；Described RS232 interface 2 and EIA485 interface 3 lays respectively at the both sides of described modular interface.
Described modular interface enclosed inside has USB RS 232 chip 4 and RS232 to turn RS422 chip 5, the usb 1 described in the connection of one end of USB RS 232 chip 4, the RS232 interface 2 described in the connection of its other end；RS232 turns the other end of the described USB RS 232 chip 4 of one end connection of RS422 chip 5, the EIA485 interface 3 described in the connection of its other end；Owing to the definition of EIA485 interface 3 is actual similar with the definition of RS422, in addition to stitch definition difference, other is essentially identical, therefore uses RS232 to turn RS422 chip 5 and carries out the data conversion of EIA485 interface 3.
As it is shown on figure 3, described RS232 interface 2 and EIA485 interface 3 all uses standard 9 needle serial port male form, in the present embodiment, in addition to the stitch used in Fig. 3, remaining stitch is not involved in data transmission.
Operation principle of the present utility model is, when using RS232 interface 2, data are directly sent to usb 1 by USB RS 232 chip 4, and when using EIA485 interface 3, data turn RS422 chip 5 and USB RS 232 chip 5 by RS232 respectively and are sent to usb 1.
Although content of the present utility model has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that the description above is not considered as restriction of the present utility model.After those skilled in the art have read foregoing, multiple amendment of the present utility model and replacement all be will be apparent from.Therefore, protection domain of the present utility model should be limited to the appended claims.
