Abstract
The utility model discloses a kind of malfunction elimination telephone set, the two ends of button (TA1) are in series with normally open contact (C3), button (TA1) is connected in circuit, the two ends of button (TA2) are parallel with normally open contact (C4), button (TA2) is connected in circuit, the output of circuit is connected with telephone circuit, telephone circuit is connected loud speaker with on the output after the circuit in parallel of button (TA1), the output of loud speaker is connected with relay indicating light, the output of relay indicating light is connected with voice distribution frame.The utility model has after the circuit redesign in ordinary telephone set, both can investigate speech channel fault, and can investigate telemechanical fault-signal again, not only ensure that the normal operation of communication routine work, also substantial saving in cost, reduce goods and materials loss, thus increase work efficiency.
Description
Technical field:
The utility model relates to a kind of circuit investigating fault, is specially adapted to Circuits System telephone set and breaks down and the investigation of remote motion signal fault.
Background technology:
When electric communication operation and maintenance protects, communication day-to-day operation maintenance workload day by day increases, when particularly phone in use breaks down, in ground investigation with when repairing fault, the process of normal use pocket telephone, when remote motion signal breaks down, use receiver remote motion signal looking up the fault, due to fault variation, the tool kind that causing communicates carries in maintenance work is numerous and diverse, should not deposit, both waste material resources, waste financial resources again.
Summary of the invention:
Task of the present utility model is that proposition is a kind of easy to use, investigates fault fast, saves a kind of malfunction elimination telephone set of maintenance cost.
Task of the present utility model completes like this, a kind of malfunction elimination telephone set, it is characterized in that: the two ends of button (TA1) are in series with normally open contact (C3), button (TA1) is connected in circuit, the two ends of button (TA2) are parallel with normally open contact (C4), button (TA2) is connected in circuit, the output of circuit is connected with telephone circuit, telephone circuit is connected loud speaker with on the output after the circuit in parallel of button (TA1), the output of loud speaker is connected with relay indicating light, the output of relay indicating light is connected with voice distribution frame.Described button ((TA1)) and button ((TA2)) are the sides being arranged on telephone set, and described loud speaker and relay indicating light are arranged on the visual panel of telephone set, are provided with electronics take-up key below described relay indicating light.
The utility model has following effect: after being redesigned by the circuit in ordinary telephone set, both can investigate speech channel fault, and can investigate telemechanical fault-signal again, not only ensure that the normal operation of communication routine work, also substantial saving in cost, reduce goods and materials loss, thus increase work efficiency.
Accompanying drawing illustrates:
Fig. 1 is the surface structure schematic diagram of telephone set; Fig. 2 is the circuit diagram of telephone set.
Embodiment:
Embodiment is described in detail in conjunction with above accompanying drawing, a side of telephone set is provided with button TA1 and TA2, the visual panel of telephone set is provided with loud speaker 6, relay indicating light 7 and electronics take-up key 3, in order to realize telephone set, both the signal of phone fault and investigation telemechanical fault can have been investigated, spy devises following circuit, as shown in Figure 2, the two ends of button TA1 are in series with normally open contact C3, button TA1 is connected in circuit, the two ends of button TA2 are in series with normally open contact C4, button TA2 is connected in circuit, the output of circuit is connected with telephone circuit 5, telephone circuit 5 is connected loud speaker 6 with on the output after the circuit in parallel of button TA1, the output of loud speaker 6 is connected with relay indicating light 8, the output of relay indicating light is connected with voice distribution frame.
During as telephone line will be investigated, click button TA2, the normally open contact C4 of at this moment series connection on button TA2 closes, and circuit communication loud speaker 6 and relay indicating light 7 work, the signal received by voice distribution frame is amplified signal by loud speaker, judges that whether telephone circuit is normal.
During as investigated remote motion signal fault, click button TA1, the normally open contact C4 of the series connection at this moment on button TA1 closes, circuit communication, loud speaker 6 and relay indicating light 7 work, the signal received by its voice distribution frame, by loud speaker, signal is amplified, judge that whether remote motion signal is normal.
Button TA1 and TA2 is also the switch of the tinkle of bells, dials bell rings toward TA1, dials the tinkle of bells be switched off toward TA2, and it is bright to click electronics take-up key 3 relay indicating light, and can dial or talk, press electronics take-up key after phone is finished, relay indicating light is bright, phone take-up.Investigate fault fast by achieving a phone part to the design of telephone circuit, substantial saving in fund cost and maintenance cost.
