Description
Technical field:
The utility model relates to Signal Terminal technical field, is specifically related to a kind of TV signal terminal branch distributor with testing agency.
Background technology:
Existing TV signal terminal branch distributor can not be known in the very first time after damage, cause maintenance time long, and work as not use for a long time or run into thunderstorm hour and the plug of output line need to be pulled up, prevent that branch distributor from damaging, its complicated operation, is used inconvenient.
Utility model content:
The purpose of this utility model is to provide a kind of TV signal terminal branch distributor with testing agency, and whether it is convenient to checkout equipment and normally works, and saves maintenance time, easy and simple to handle, easy to use.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises shell 1, input interface 2, output interface 3, installing rack 4, change-over circuit plate 5, it also comprises diverter switch 6, indicator light 1, indicator light 28, relay one KM1, relay two KM2, the both sides of shell 1 are all provided with installing rack 4, on installing rack 4, be provided with installing hole 4-1, the two ends of shell 1 are separately installed with input interface 2 and two output interfaces 3, input interface 2 is connected with the input of change-over circuit plate 5 by wire, and 6, two output interfaces 3 of diverter switch are installed on wire and by connecting wire, are connected with the output of change-over circuit plate 5 respectively, and two connection wires respectively with the coil of relay one KM1, the coil of relay two KM2 connects, one end of diverter switch 6 respectively with one end of relay one KM1 normally opened contact KM1-1, one end of relay two KM2 normally opened contact KM2-1 connects, the other end of relay one KM1 normally opened contact KM1-1, the other end of relay two KM2 normally opened contact KM2-1 respectively with indicator light 1, indicator light 28 connects.
Operation principle of the present utility model is: during use at input interface 2, output interface 3 is installed input, outlet, then press diverter switch 6, the coil of relay one KM1 now, the coil of relay two KM2 obtains electric, relay one KM1 normally opened contact KM1-1, relay two KM2 normally opened contact KM2-1 are closed, indicator light 1, indicator light 28 is all in running order, proof branch distributor is normally worked, otherwise damage, when running into thunder and lightning or not using for a long time, only diverter switch 6 need to be closed, do not need the plug of output line to pull up, easy and simple to handle, easy to use.
The utlity model has following beneficial effect: be convenient to checkout equipment and whether normally work, save maintenance time, easy and simple to handle, easy to use.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit connection diagram of the present utility model.
Embodiment:
Referring to Fig. 1-Fig. 2, this embodiment adopts following technical scheme: it comprises shell 1, input interface 2, output interface 3, installing rack 4, change-over circuit plate 5, it also comprises diverter switch 6, indicator light 1, indicator light 28, relay one KM1, relay two KM2, the both sides of shell 1 are all provided with installing rack 4, on installing rack 4, be provided with installing hole 4-1, the two ends of shell 1 are separately installed with input interface 2 and two output interfaces 3, input interface 2 is connected with the input of change-over circuit plate 5 by wire, and 6, two output interfaces 3 of diverter switch are installed on wire and by connecting wire, are connected with the output of change-over circuit plate 5 respectively, and two connection wires respectively with the coil of relay one KM1, the coil of relay two KM2 connects, one end of diverter switch 6 respectively with one end of relay one KM1 normally opened contact KM1-1, one end of relay two KM2 normally opened contact KM2-1 connects, the other end of relay one KM1 normally opened contact KM1-1, the other end of relay two KM2 normally opened contact KM2-1 respectively with indicator light 1, indicator light 28 connects.
The operation principle of this embodiment is: during use at input interface 2, output interface 3 is installed input, outlet, then press diverter switch 6, the coil of relay one KM1 now, the coil of relay two KM2 obtains electric, relay one KM1 normally opened contact KM1-1, relay two KM2 normally opened contact KM2-1 are closed, indicator light 1, indicator light 28 is all in running order, proof branch distributor is normally worked, otherwise damage, when running into thunder and lightning or not using for a long time, only diverter switch 6 need to be closed, do not need the plug of output line to pull up, easy and simple to handle, easy to use.
This embodiment has following beneficial effect: is convenient to checkout equipment and whether normally works, save maintenance time, and easy and simple to handle, easy to use.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
