Abstract
The utility model discloses a low frequency through EOC jumper which comprises an over current unit, a mixed signal separation unit, a high-low frequency signal mixing unit and over current unit which are connected in sequence; the mixed signal separation unit is connected with a high frequency signal output port, and the high-low frequency signal mixing unit is connected with a high frequency signal input port. The lower frequency through EOC jumper is additionally provided with the over current units to support over current and carry out the over current effect on the 60V voltage line, and accordingly solves the problem that the coaxial line with 60V line is difficult to be reconstructed.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of communication equipment, relates in particular to the straight-through EOC jumper of a kind of low frequency.
Background technology
Development along with integration of three networks technology, increasing EOC technology produces, but because the circuit of broadcasting and TV has decay, so be added with amplifier in the centre, also, there is not the transmitted in both directions performance, present EOC Technology Need transmitted in both directions because the network of former broadcasting and TV is one-way fashions, so we will transform the amplifier of broadcasting and TV, make its energy transmitted in both directions.Amplifier also has the amplifier effect to low frequency signal, so we need auxiliary equipment that amplifier is carried out cross-over connection, makes its low frequency signal not be exaggerated distortion.The equipment of bridging amplifier has only flow pattern and flow pattern excessively, but the flow pattern jumper does not have the overcurrent unit, can not have a very big difficult problem to present CHINA RFTCOM Co Ltd transformation with the circuit that the 60V power supply is arranged in the line.
The utility model content
The technical problem that the utility model mainly solves provides a kind of can being used in and supports the low frequency of 60V power supply to lead directly to the EOC jumper in the broadcasting and TV circuit.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of low frequency to lead directly to the EOC jumper, comprise the overcurrent unit, mixed signal separative element, low-and high-frequency signal mixed cell, the overcurrent unit that connect successively, described mixed signal separative element connects high-frequency signal outlet, and described low-and high-frequency signal mixed cell is connected with high-frequency signal inlet.
Wherein, described mixed signal separative element is connected by an amplifier with described low-and high-frequency signal mixed cell.
Wherein, described overcurrent unit is connected with coaxial cable.
The beneficial effects of the utility model are: can not there be the very situation of hang-up in the only flow pattern jumper of difference prior art to present CHINA RFTCOM Co Ltd transformation with the circuit that the 60V power supply is arranged in the line.The utility model supports the straight-through EOC jumper of the low frequency of overcurrent by increasing the overcurrent unit, by the overcurrent unit 60V voltage in the circuit is carried out the overcurrent effect, solves the problem that has 60V track remodelling difficulty in the prior art in the coaxial line.

Fig. 1 is the theory diagram of a kind of embodiment of the straight-through EOC jumper of the utility model low frequency;
Fig. 2 is the theory diagram of another embodiment of the straight-through EOC jumper of the utility model low frequency.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1, first embodiment of the straight-through EOC jumper of the utility model low frequency, it comprises a coaxial line cable 16, an overcurrent unit 11, a mixed signal separative element 12, a low-and high-frequency signal mixed cell 14, an overcurrent unit 15, a coaxial line cable 16 that connects successively.Described mixed signal separative element 12 connects high-frequency signal outlet 17, and described low-and high-frequency signal mixed cell 14 is connected with high-frequency signal inlet 18.
Signal enters overcurrent unit 11 from coaxial cable 16, again through described mixed signal separative element 12 isolated high and low frequency signals, isolated high-frequency signal is through high-frequency signal outlet 17 outputs, isolated low frequency signal mixes low-and high-frequency signal mixed cell 14 with the high-frequency signal of importing from high-frequency signal inlet 18, and mixed signal is exported mixed signal through overcurrent unit 15 and by coaxial cable 16.
See also Fig. 2, in another embodiment, be connected by an amplifier 13 between described mixed signal separative element 12 and the described low-and high-frequency signal mixed cell 14.Described mixed signal separative element 12 isolated high and low frequency signals, isolated high-frequency signal is through high-frequency signal outlet 17 outputs, isolated low frequency signal amplifies the back by described amplifier 13 to be mixed low-and high-frequency signal mixed cell 14 with the high-frequency signal of importing from high-frequency signal inlet 18, and mixed signal is exported mixed signal by overcurrent unit 15 and by coaxial cable 16.
Described overcurrent unit 11 connects the mixed signal separative element to be realized 60V voltage in the circuit is carried out the overcurrent effect, is convenient to the transformation of existing CHINA RFTCOM Co Ltd.
Can not there be the very situation of hang-up in the only flow pattern jumper of difference prior art to present CHINA RFTCOM Co Ltd transformation with the circuit that the 60V power supply is arranged in the line.The utility model supports the straight-through EOC jumper of the low frequency of overcurrent by increasing the overcurrent unit, by the overcurrent unit 60V voltage in the circuit is carried out the overcurrent effect, solves the problem that has 60V track remodelling difficulty in the prior art in the coaxial line.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
Claims (3)
