The technical problems to be solved in the utility model is: provide a kind of telephone line switch accuracy high, switch telephone line switcher timely.
The utility model solves the technical scheme that its technical problem adopts: a kind of telephone line switcher, comprises control relay circuit; Described control relay circuit has multiple input interface and multiple output interface; Described each output interface connects a phone set terminal respectively; Described each input interface has positive pole and negative pole; The positive pole of described all input interfaces is connected on same voice trunks equipment simultaneously; The negative pole of described all input interfaces is connected on another voice trunks equipment simultaneously; The corresponding output interface of a described input interface; Described control relay circuit is also connected with two buttons; The voice trunks equipment that one of them control positive pole of described button connects is communicated with; The voice trunks equipment that another button control negative pole connects is communicated with.
Further, each input interface described in the utility model is connected with a light-emitting diode.
Further say, the number of output interface described in the utility model is 4; The number of described input interface is 8.
Further say, voice trunks equipment described in the utility model one of them be speech adapter; Another is Digital Data Net.
Further say, control relay circuit described in the utility model connects 12V DC power supply.
The utility model, according to the characteristics design circuit of relay, by input, exports the core of RJ11 interface respectively by different Controls, controls different input RJ11 interfaces and export RJ11 interface UNICOM by control relay.For improving the reliability of switch, circuit design is self-locking and interlocking, and after pressing the button, switch circuit switched also keeps this state, now this button useless, until after pressing another button, switch switches to another circuit and keeps.By circuit design, for each input RJ11 interface increases a light-emitting diode, but this diode only has and just works under a kind of pattern wherein, and namely user can judge the operating state of switch by light-emitting diode.Simultaneously due to diode and relay associating in circuit design, also judge the operating state of relay by diode.This switch mode changes place frequently at telephone line and is suitable for, simultaneously according to this switch mode modification circuits, can realize one export RJ11 interface and three even more input RJ11 interface UNICOM, also can increase the quantity simultaneously switching telephone line.Greatly mention the reliability of circuit.
The beneficial effects of the utility model are, solve the defect existed in background technology, telephone line under different communication modes and user terminal are fixed by switch, when communication pattern switches, only need a button of switch, telephone line can be realized switch, promote the accuracy that post personnel switch telephone line, shorten switching time.

Embodiment
With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of telephone line switcher as shown in Figure 1, is made up of control relay circuit, RJ11 interface, light-emitting diode, button, power supply.
Speech adapter and DDN (Digital Data Net) are two kinds of voice trunks equipment that current boats and ships use, and can control phone set terminal use any voice trunks by switch.The components and parts such as relay, RJ11 interface, light-emitting diode, button, power supply of switch complete assembling on one piece of circuit board, wherein RJ11 interface, light-emitting diode, button, power supply are all connected with control relay circuit, " 1+ ", " 1-" two input corresponding " 1 " exports, by that analogy."+" represents that the type interface is connected with same voice trunks, and "-" represents and be connected with another voice trunks.When pressing left side button, "+" style interface and corresponding output interface UNICOM, now this button useless, this UNICOM's state keeps, until when pressing right-hand button, and "-" style interface and corresponding output interface UNICOM, and hold mode, meanwhile, light-emitting diode is bright.
Switch can ensure that output interface is connected with a road input interface all the time, even if switch supply line breaks down, utilize the characteristic of the normally closed electric shock of relay and common conducting, under still ensureing that switch is operated in a kind of communication pattern, improve the reliability of telephone line.The switching of telephone line is realized by button, and therefore control relay circuit needs self-locking and interlock function, when pressing one of them button, circuit turn-on, and energy hold mode, until press another button, state switches.Control relay circuit figure is as shown in Figure 2:
Under initial condition, spring push-button switch S1, S2 disconnect, and relay K 1 normally opened contact and common disconnect, and relay K 2 normally-closed contact is connected with common, and now the equal no current of relay K 1 ~ K10 coil passes through.When pressing the button S1, K1 coil has electric current to pass through, and K1 normally opened contact is connected with common, and now K3 ~ K10 coil has electric current to pass through.When S1 resets, because K1 coil still has electric current to pass through, then circuit state keeps, and S1 button no longer works, relay coil obtain electric after, utilize the auxiliary contact of often opening of self to keep the on-state in loop, i.e. self-locking.
When pressing the button S2, K2 coil has electric current to pass through, then K2 normally-closed contact and common disconnect, K1 coil blackout, and K1 normally opened contact is connected with common and disconnects, and now Circuit Interrupt, K3 ~ K10 coil does not have electric current to pass through.When S2 resets, Circuit Interrupt, K2 coil no current passes through, and now K2 normally-closed contact is connected with common, and circuit reverts to initial condition, and S2 button no longer works.Utilize K2 coil to form current circuit, control the current circuit of whole control relay circuit, namely interlock.
In sum, control relay circuit has two states, and K3 ~ K10 coil has electric current by passing through with no current simultaneously, and this two states can realize switching respectively by button S1, S2.According to this characteristic, for relay K 3 and K4, by connecting RJ11 interface shown in Fig. 3:
When K3, K4 coil has electric current through out-of-date, relay normally open contact is connected with common, and now input interface " 1-" is connected with output interface " 1 ".When K3, K4 coil does not have electric current through out-of-date, relay normally-closed contact is connected with common, and now input interface " 1+ " is connected with output interface " 1 ".Other several RJ11 interfaces and relay annexation by that analogy, have no current to pass through by button S1, S2 control K3 ~ K10 coil, and then control a wherein road input RJ11 interface and be connected with output interface.
In the design shown in Fig. 3, only using the contact of relay side, for making full use of resource, and improving circuit reliability, the utility model increases a light-emitting diode when designing for each relay, circuit diagram as shown in Figure 4:
When relay coil has electric current through out-of-date, normally opened contact is connected with common, and now light-emitting diode has electric current to pass through.Therefore by the operating state of the condition adjudgement switch of light-emitting diode and coupled relay work whether normal.
Through overtesting, switch circuit design is correct, working properly, and use switch to switch telephone line in certain period of going to sea, accuracy reaches 100%, and average switching time is within 30 seconds.
The just embodiment of the present utility model described in above specification, various illustrating is not construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of utility model.
