Abstract
A communication digital distribution frame (DDF) 2M signal detector comprises a radio frequency coaxial connector which is provided with a thread locking mechanism, and a luminous body. The luminous body is connected with the radio frequency coaxial connector which is provided with the thread locking mechanism through a coaxial line. The communication DDF 2M signal detector can be used to quickly, accurately and visually detect whether connection of a 2M circuit on the DDF is correct or not. The communication DDF 2M signal detector with improved work efficiency has the advantages of being good in practicability, high in efficiency, light and fast, low in cost and easy to popularize.
Description
Technical field
The utility model relates to a kind of signal detector, particularly a kind of communication DDF frame 2M signal detector.
Background technology
Fast and stable development along with electric power system in recent years; Secondary devices such as substation relay protection, automation, monitoring are increasing; The usage quantity of 2M circuit also strengthens thereupon; The whole tandems of these circuit through switching in the frame, get into transmission equipment on communication DDF (communication DDF refers to the digital distribution of communication) frame.In case newly-increased circuit; The Communication Personnel will carry out the wire jumper between user equipment side and transmission equipment side on communication DDF frame, wire jumper connects correctness, and whether receiving and transmitting signal is normal; Generally be to judge through query transmission equipment network management information or connection instrument; But webmaster is installed in the far-end main website more, and needing main website to have the Communication Personnel to cooperate could accomplish, and instrument is carried inconvenience.
The utility model content
The purpose of the utility model is to overcome the weak point of prior art, and whether correct, the communication DDF frame 2M signal detector of increasing work efficiency if providing a kind of 2M circuit that can detect fast, accurately, intuitively on the DDF frame to connect.
A kind of communication DDF frame 2M signal detector, its structural feature is: include the radio frequency (RF) coaxial connector with thread lock mechanism, be connected through coaxial line between the luminous element, luminous element and thread lock mechanism radio frequency (RF) coaxial connector.
During use, after the 2M cable of communication DDF frame rear side connected, the transmission equipment side of plate transmitting-receiving port was plugged the 2M detector in front; If luminous element is luminous; Show that then this port is the transmission signal port of transmission equipment,, show that then this port is the reception signal port of transmission equipment if luminous element is not luminous; If two ports are all not luminous, show that then possibly there is fault in the connection line between transmission equipment and the DDF frame.In like manner; Re-use the sending and receiving port that the 2M detector detects user equipment side; Follow the principle (being that the transmission equipment transmit port connects the subscriber equipment receiving port, the transmission equipment receiving port connects the subscriber equipment transmit port) that optical port connects no optical port then; With connector the transmission equipment side is linked to each other with the port of user equipment side, the transmitting-receiving that can fast and accurately inerrably accomplish the 2M circuit like this connects.
Described luminous element is a light-emitting diode.
Light-emitting diode specifically is connected to coaxial line: the heart yearn of coaxial line one end is linked to each other with a pin of light-emitting diode; The screen of coaxial line links to each other with another root pin of light-emitting diode; And use insulating tape that two pins are isolated, put heat-shrink tube at connecting portion at last and carry out reinforcement protection.
In sum, the utility model is compared the following advantage of prior art:
Whether the 2M circuit that the communication DDF frame 2M signal detector of the utility model can detect on the DDF frame fast, accurately, intuitively connects correct; The communication DDF frame 2M signal detector of increasing work efficiency; Have that practicality is good, efficient is high, light and fast, with low cost, the advantage of very easily promoting.
