Abstract

The utility model relates to a faxaphone switching device, which is composed of relays K1, K2, a capacitor C, resistors R1, R2, and a photocoupler H. The utility model is characterized in that the relay K1 is fixedly connected with conductive wires L1 and L2, and is movably connected with conductive wires L3 and L4 or L5 and L6; the relay K2 is fixedly connected with conductive wires L9 and L10, and is movably connected with conductive wires L7 and L8 or L11 and L12; the capacitor C is connected with a conductive wire L1; the capacitor C and the photocoupler H are connected with the conductive wire L7 together; the photocoupler H and the resistor R1 are connected with a conductive wire L2 together by the resistor R2 is connected with the conductive wire L8; the conductive wires L5 and L6 are respectively connected with the conductive wires L11 and L12. The utility model can be provided with the function of a fax by a telephone set. The utility model has the advantages of monitoring ringing, simple structure, and complete function.

Description

The fax telephone switching device
The utility model relates to the fax telephone switching device that a kind of facsimile machine is used.
Usually, the fax telephone built-up circuit in the facsimile machine all is to utilize relay under holding state, provides telephone line and external telephone set or facsimile machine for oneself closing of the circuit, but number dialing telephone call.Just telephone line is transferred on the channel of facsimile when sending a fax, when facsimile finished, the telegram in reply phone of again telephone line being transferred used very inconvenient.If small-sized facsimile function is incomplete yet.
The purpose of this utility model be to provide a kind of can be by make to realize to be provided with facsimile function, monitoring ring, simple in structure, multiple functional fax telephone switching device in the telephone set drilling.
The purpose of this utility model is achieved in that the fax telephone switching device, is by connecting lead, relay K 1, K2, capacitor C, resistance R 1And R 2, photoelectrical coupler H constitutes relay K jointly 1With lead L 1, L 2For fixedly connected, with lead L 3, L 4Or L 5, L 6Connect relay K for living 2With lead L 9, L 10For fixedly connected, with lead L 7, L 8Or L 11, L 12Connect capacitor C one end and lead L for living 1Be connected, the other end and photoelectrical coupler H together with lead L 7Be connected, the other end of photoelectrical coupler H is through resistance R 2And resistance R 1Together with lead L 2Be connected resistance R 1The other end connect lead L 8, lead L 5, L 6The respectively corresponding lead L that connects of the other end 11, L 12
The utility model is owing to adopt said structure, can be by realizing control at the phone hands-operation to facsimile machine, and can finish setting by the button on the telephone set to facsimile function, simple in structure, multiple functional.
Provide specific embodiment below in conjunction with accompanying drawing, further specify the utility model and how to realize.
Fig. 1. the utility model circuit principle structure figure
Wherein: L 1-L 12. connect lead, C. electric capacity, R. resistance, K 1, K 2. relay, H. photoelectrical coupler, R 1, R 2. resistance.As shown in Figure 1, the fax telephone switching device is by connecting lead, relay K 1, K 2, capacitor C, resistance R 1And R 2, photoelectrical coupler H constitutes relay K jointly 1With lead L 1, L 2For fixedly connected, with lead L 3, L 4Or L 5, L 6Connect relay K for living 2With lead L 9, L 10For fixedly connected, with lead L 7, L 8Or L 11, L 12Connect capacitor C one end and lead L for living 1Be connected, the other end and photoelectrical coupler H together with lead L 7Be connected, the other end of photoelectrical coupler H is through resistance R 2And resistance R 1Together with lead L 2Be connected resistance R 1The other end connect lead L 8, lead L 5, L 6The respectively corresponding lead L that connects of the other end 11, L 12
Work as K 1With L 1With L 3, L 2With L 4Connect respectively; K 2With L 7With L 9, L 8With L 10When connecting respectively, L 3And L 4Supply direct current to telephone set, thereby can send signal, through resistance R by telephone key 1, capacitor C is sent to fax modem, and facsimile machine is carried out function setting, simultaneously because L 1With L 5, L 2With L 6Be in off-state, the signal that telephone set sends at this moment can not enter the L that links to each other with telephone line 11, L 12
Work as K 1With L 1With L 5, L 2With L 6When connecting respectively, resistance R 1, capacitor C, photoelectronic coupler H and resistance R 2Can be to from the L that links to each other with telephone line 11, L 12On bell signal detect and monitor.
Work as K 2With L 11With L 9, L 12With L 10When connecting respectively, exchange line L 11And L 12On facsimile signal just can import fax modem into.
Said apparatus can be arranged on the facsimile machine circuit board.
