Description
Technical field
The utility model relates to the 2M network channel fault detection technique fields in electric system, and in particular to a kind of electric power
The cable passage 2M fast detector in system.
Background technique
The business of 2M circuit is more and more in Optical Transmission Network OTN, and when service disconnection, operation maintenance personnel needs to carry out fault location,
Judge cable quality, the transmitting-receiving port of differentiation equipment is the important step of troubleshooting.But in practical work, due to 2M event
The sudden needs of barrier are temporarily handled, and 2M code error tester limited amount can not be accomplished to carry；In more situations
Staff only needs the quality of test cable, and it is necessary to use 2M code error tester.Such common solution of failure
It is using multimeter test conduction, but often due to the contact of 2M coaxial connector is smaller, pen meter of universal meter is relatively thick,
There is inconvenience when test, the effect is unsatisfactory.
Summary of the invention
To solve the above-mentioned problems, it quickly detects the cable passage 2M that the utility model provides in a kind of electric system
Instrument, specific technical solution are as follows:
A kind of cable passage 2M fast detector in electric system includes 2M coaxial connector, light emitting diode；It is described
Light emitting diode is fixedly connected with 2M coaxial connector.
Preferably, the anode of the light emitting diode is connect with the core wire contact pin of 2M coaxial connector, the light-emitting diodes
The cathode of pipe is connect with the insulated hull of 2M coaxial connector.
Preferably, the 2M coaxial connector is BNC-J or L9-J head.
Preferably, the light emitting diode is red light emitting diodes.
The utility model has the following beneficial effects: the utility model has the advantages of simple structure, low manufacture cost can be easily and fast
Judge transmitting-receiving port and the quality of cable of the port 2M, and more intuitive using diode displaying.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein, 1:2M coaxial connector, 2: light emitting diode.
Specific embodiment
In order to better understand the utility model, the utility model is made in the following with reference to the drawings and specific embodiments further
Illustrate:
A kind of cable passage 2M fast detector in electric system includes 2M coaxial connector 1, light emitting diode 2；Hair
Optical diode 2 is fixedly connected with 2M coaxial connector 1.Wherein, the core wire of the anode and 2M coaxial connector 1 of light emitting diode 2
Contact pin connection, the cathode of light emitting diode 2 are connect with the insulated hull of 2M coaxial connector 1.2M coaxial connector 1 uses BNC-J
Head or L9-J head.
The color effects of light emitting diode are useful in different voltages rate range, yellow, red applicable voltage class model
It encloses for 1.75-1.83V, the voltage class ranges that the applicable voltage class ranges of green, yellow are 2.0-2.13V, blue is applicable
For 3.35-3.45V, to guarantee visual effect, more the port intuitive judgment 2M whether failure, the light emitting diode 2 of the present embodiment
For red light emitting diodes.
In the experience of multiple malfunction elimination, can obtain 2M hair port voltage is direct current 2.0V or so, and light emitting diode
Conducting voltage is also 2V or so.Therefore may determine that whether the port 2M is faulty using light emitting diode, but light emitting diode
It is small in size, it has not been convenient to carry, therefore connect with 2M coaxial connector using light emitting diode so that light emitting diode easily with
The connection of the port 2M.
The production method of the utility model are as follows: by the anode of light emitting diode 2 using scolding tin and BNC-J or L9-J head
Core wire contact pin connection, the cathode of light emitting diode is connect with the insulated hull of BNC-J or L9-J.
The use process of the utility model are as follows: the DDF distributing frame in communications equipment room protocol converter pond is on probation, light-emitting diodes
Pipe 2 is lighted, and illustrates that the utility model has been inserted in the equipment hair port (TX) and cable work is good.Light emitting diode 2 cannot be lighted,
Then prove that the utility model has been inserted in the equipment receipts port (RX) or cable breaks down.Judge whether cable is normal at this time, only needs
It exchanges protocol converter to receive and dispatch port connection, if can light light emitting diode 2 proves that cable is good；It cannot such as light luminous
Diode then proves that cable is faulty.
The utility model is not limited to above-described specific embodiment, and the foregoing is merely the preferable of the utility model
Case study on implementation is not intended to limit the utility model, made within the spirit and principle of the present invention any
Modifications, equivalent substitutions and improvements etc., should be included within the scope of protection of this utility model.
