The utility model relates to the technical field of a audio test on a communication terminal total distribution frame and provides a universal audio distribution frame test cord. The universal audio-frequency distribution frame test cord comprises an insulating housing, a test circuit board is disposed in the insulating housing, the test circuit board is composed of a control circuit, a sampling circuit, input contact terminals and output contact terminals, test probes are welded onto the input contact terminals, the test probes are needle-like, needle heads of the test probes are round and smooth, the length of each probe is 2cm to 5cm, the maximum diameter of each test probe is no more than 3mm, and a telephone set joint is connected to the output contact terminals. Improvements are performed on the basis of existing equipment, the adopted test circuit board is from a test circuit board of an existing test cord, and replacement money of equipment is greatly saved. One test cord provided by utility model can test audio signals on different modules, so people do not need to replace test cords back and forth; and the universal audio distribution frame test cord is convenient, efficient, simple in structure and easy to carry, and is suitable for popularization and application in the electric power industry.
Description
Technical field
The utility model relates to the audio-frequency test technical field on communication terminal main frame, specifically a kind of general-purpose voice distribution frame test cord.
Background technology
Voice frequency distributing main frame is provided with many Wiring modules, on Wiring module, be provided with testing jack, the testing jack difference of the Wiring module on different voice frequency distributing main frames, therefore carry out signal tone test on different voice frequency distributing main frames time, needed test cord model is also different, and voice frequency distributing main frame kind used is more in a transformer station, tester is in order to complete test signal sound, need carry a complete set of test cord, so equipment purchase fund and maintenance cost have been increased, two in the time not carrying the test cord of certain specification, need routing audition, waste time and energy, be unfavorable for the fast development of industry.The analysis found that, existing test cord structure comprises testing circuit board, on the input contact of testing circuit board, be connected with inserted sheet, on the output contact of testing circuit board, be connected with signal lamp, in testing circuit board, comprise control circuit and sample circuit, and between different test cords only inner inserted sheet specification distinguish to some extent, it is short that the length that inserted sheet has has, wide have narrow having.
Utility model content
Applicant, in communication line service work for many years, finds the problems referred to above, and through exploring and research, object is to provide a kind of general-purpose voice distribution frame test cord, solves existing test event rope specification many, problem that can not be general.
The technical scheme that the utility model is taked for its technical problem of solution is, design a kind of general-purpose voice distribution frame test cord, its structure comprises: insulation crust, in insulation crust, be provided with testing circuit board, testing circuit board is made up of control circuit, sample circuit, input contact and output contact, wherein on described input contact, weld test probe, test probe is needle-like, the syringe needle of test probe is mellow and full, the length of test probe is 2-5cm, the maximum gauge of test probe is no more than 3mm, on described output contact, is connected with telephone set joint.
The beneficial effects of the utility model: this novel test cord is to improve based on existing equipment, the testing circuit board adopting is from the testing circuit board of existing test cord, save in a large number equipment replacement fund, the test probe of needle-like can be applicable to the voice frequency distributing module of all size, this novel test cord just can be tested the audio signal on disparate modules, need not change back and forth test cord, convenient and swift, simple in structure being easy to carry, is adapted at applying in power industry.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of general-purpose voice distribution frame of the utility model test cord.
Embodiment
Referring to Fig. 1, a kind of general-purpose voice distribution frame test cord, its structure comprises: insulation crust 1, in insulation crust 1, be provided with testing circuit board 2, testing circuit board 2 is by control circuit, sample circuit, input contact 3 and output contact 4 form, this testing circuit board 2 can be selected the circuit board in existing test cord, also can select the circuit board in FA820D type security device, wherein, on described input contact 3, weld test probe 5, test probe 5 is needle-like, the syringe needle of test probe 5 is mellow and full, the length of test probe 5 is 2-5cm, the maximum gauge of test probe 5 is no more than 3mm, on described output contact 4, be connected with telephone set joint 6.
