Abstract
Disclosed is an adapter of receiving aerial of an active television, comprising a power transformer, supply lines, an aerial terminal, television terminals and a coupled circuit, wherein the aerial terminal and the television terminals are respectively fixed on the different side surfaces of an outer casing, the coupled circuit is connected between the aerial terminal and the television terminals, the power transformer is positioned at the external end of the supply lines, and the power transformer is combined with a power plug. The number of the television terminals is two. A first television terminal is a coaxial plug engaged with aerial plug of the television and is disposed at one end of the outer casing. The aerial terminal and a second television terminal are arranged on other side surfaces of the outer casing. The utility model has the advantages that the added television interface not only can be used by two sets of televisions, but also can be used as a hitching device divided into two sections of the cable television aerial in the condition of no power connection. Because the power transformer is not installed inside the adapter, thereby the volume is reduced greatly, the circuit connectors are decreased, the occupied space is reduced and the appearance is more beautiful, being capable of being directly inserted into the aerial plug of the television.
Description
Technical field
The utility model relates to television receiving antenna, particularly a kind of active tv reception antenna adapter.
Background technology
The structure of existing active tv reception antenna is: outdoor antenna oscillator is connected with the antenna amplifier antennafire input, signal after the output of this antenna amplifier antennafire will amplify by coaxial cable is delivered to indoor, and be connected with adapter, in this transducer power transformer is arranged, it provides low-voltage alternating current power supply by above-mentioned coaxial cable to antenna amplifier antennafire; Adapter also provides signal output and is connected with the TV set aerial mouth by cable.The shortcoming of this translator is to have only a television interface, can not satisfy the user's that two above television receivers are arranged requirement, again owing to have power transformer to make its volume big in it, can not directly be connected with television set, must be by a cable, increase line contacts, both increased cost, reduced reliability again.
Summary of the invention
The purpose of this utility model just provides a kind of two television interfaces active tv reception antenna adapter that also energy is direct and TV is pegged graft that has.
Technical solutions of the utility model are: comprise power transformer and power line, antenna terminal, TV terminal, coupling circuit, antenna terminal and TV terminal are separately fixed on the not ipsilateral of described shell, be connected with coupling circuit between the two, described power transformer is positioned at the outer end of power line, and with attaching plug be one; Described TV terminal has two, and wherein the first TV terminal is the coaxial plug that cooperates with the TV set aerial socket, and it is positioned at an end of described shell, and the described antenna terminal and the second TV terminal are positioned at other side of described shell.
One end of described shell is flat cuboid, and the other end is a bucking ladder, and the described first TV terminal is positioned at the upper base of this bucking ladder, and the described antenna terminal and the second TV terminal all are coaxial sockets, all are positioned at the other end of the flat cuboid of shell; Described power line is connected in the end face of this flat cuboid.
Described coupling circuit is: the skin of described three terminals interconnects, respectively connect between the axle core of antenna terminal axle core and two TV terminals a capacitor C 1, C2, and series inductance L and capacitor C 3 between the skin, and antenna terminal also is connected with power line.
The utility model advantage is: increased television interface and used not only can be for two television identical the time, also can be under the situation that does not connect power supply have used as the split device of the one-to-two of cable TV antenna; Because power transformer is not interposing in the transducer, its volume is greatly reduced, it directly can be plugged on the antenna socket of television set, reduced line joint, improved the quality of reception, also reduced take up room, more attractive in appearance.
Below in conjunction with drawings and Examples the utility model is further specified.
