Description

A kind of novel Splitter

Technical field

The present invention relates to communication technical field, relate in particular to a kind of Splitter technology.

Background technology

ADSL (asymmetric digital subscriber line) access technology is a kind of broadband access technology, it can provide high transfer rate, and can make full use of existing twisted pair telephone network, only needing install additional at the circuit two ends ADSL communication terminal equipment promptly can be the user broadband service is provided, need not do any change to existing line, thus the ADSL access technology in the use tool have great advantage.

The ADSL access technology is the professional and broadband data service use the same line road of call voice in use, 40KHz is with super band (high frequency) transmission data, the following frequency range of 40KHz (low frequency) is used for transporting speech, user side comes the high and low frequency Signal Separation by Splitter, and the high-frequency signal after will separating is then sent into computer; Low frequency signal is sent into telephone set; Therefore, not interfere with each other for guaranteeing the user to enjoy data service and speech business simultaneously be vital to the performance of Splitter.

In realizing invention process of the present utility model, the inventor finds existing Splitter, and there are the following problems at least: structure is comparatively complicated, is difficult to realize high-quality production in enormous quantities.

Summary of the invention

The utility model embodiment provides a kind of simple structure, the Splitter equipment that is suitable for producing in enormous quantities.

A kind of Splitter comprises: signal input part; This signal input part is connected with low frequency signal and selects circuit and high-frequency signal to select circuit.

In embodiments of the present invention, the ADSL signal is imported from signal input part, described ADSL signal comprises low frequency voice signal and high-frequency data signal, signal input part is sent to low frequency signal respectively with described ADSL signal and selects circuit and high-frequency signal to select circuit, low frequency signal selects circuit with the high-frequency signal filtering, and the low frequency voice signal is sent to voice terminal device, high-frequency signal selects circuit with the low frequency signal filtering, and high-frequency data signal is sent to data terminal equipment, thereby realized that speech business and data service are by the same line road transmission and do not disturb mutually, and compare simple structure with existing Related product, be easy to realize large batch of production.

Embodiment

In order to solve comparatively complexity of present Splitter product configurations, be difficult to realize the problem of large-scale production, the utility model provides a kind of simple structure and well behaved Splitter.

The utility model Splitter as shown in Figure 1, comprising: signal input part 1; This signal input part is connected with low frequency signal and selects circuit 2 and high-frequency signal to select circuit 3.

As shown in Figure 2, high-frequency signal selects circuit to comprise two filter capacitor C5 and C6; C5 one end links to each other with signal input part 201, and the other end links to each other with output 203; C6 one end links to each other with signal input part 202, and the other end links to each other with output 204; Output 203,204 directly is connected with computer, and C5 and C6 are 120nF/400V.

Low frequency signal selects circuit to comprise four filter inductances (two 11 same phase transformer) L1 and L2, L3 and L4, presses the phase directional of schematic diagram during connection; L1 one end links to each other with signal input part 201, and the other end links to each other with the end of L3, and the other end of L3 links to each other with signal output part 205, and L2 one end links to each other with signal input part 202, and the other end links to each other with the end of L4, and the other end of L4 links to each other with signal output part 206; Signal output part 205,206 directly links to each other with telephone set, and L1, L2, L3 and L4 are 6.6mH.

Low frequency signal selects circuit also to comprise four capacitor C 1, C2, C3 and C4; C1 is series between L1 and the L3; C2 is series between L3 and the L4; C3 and L4 are in parallel; C4 and L3 are in parallel; Wherein C1 is 68nF/400v, and C2 is 8.2nF/400v, and C3 and C4 are 2.2nF/100v.

Use connected mode of the present utility model, as shown in Figure 3, this ADSL Splitter, LI NE port is its signal input port, DATA (data service) port is its data-out port, links to each other with the ADSLMODEM (modulator-demodulator) of computer PC; POTS (telephone service) is its voice output port, links to each other with telephone set.

The utility model can be realized the isolation fully of DATA signal and POTS signal on function, functional, by Institute of Telecommunication Transmission of the Ministry of Information Industry's test, meet YD/T1187-2002, asymmetric numeral, subscribers feeder (ADSL) standard meets the UL1950 standard.

The utility model is simple in structure, and all adopts special-purpose passive device to form, and plug connector adopts the gold-plated coating of special thickening, not only can guarantee that it has adaptability preferably to operational environment, and is suitable for the large batch of production of procedure.It below is the Splitter test parameter.

The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion by described protection range with claim.
