Description
Technical field
The utility model relates to a kind of audio-frequency test instrument, particularly a kind of earphone-type audio-frequency test instrument.
Background technology
Audio-frequency test instrument is used to the audio frequency testing cable, determines with this tester whether telephone line is connected.At present, audio-frequency test instrument common on market mostly is " mobile phone type " audio-frequency test instrument, its mechanism for testing similar to mobile phone by structure and two calibrating terminals are formed, during use, two staff are needed to coordinate, namely one of them staff needs two calibrating terminals to contact with the copper core of cable respectively, and another staff then needs mechanism for testing to be put near ear, completes the monitoring work of tested cable audio frequency., there is the drawback of taking people's effort in complicated operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of design science reasonable, easy to operate, economize people laborsaving, be easy to realize earphone-type audio-frequency test instrument.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of earphone-type audio-frequency test instrument, comprise mechanism for testing and calibrating terminal, the audio-frequency test end of mechanism for testing is connected with two wires, a calibrating terminal is connected respectively in the end of two wires, it is characterized in that: on the control end of described mechanism for testing, be provided with earphone plug-in opening, this earphone plug-in opening is fitted with test earphone, is shaped with a mounting groove at the back side of described mechanism for testing, in this mounting groove, be fitted with a spring leaf.
And described test earphone is PlayGear Stealth.
Advantage of the present utility model and good effect are:
1, this earphone-type audio-frequency test instrument, by traditional mobile phone type audio-frequency test instrument is designed to earphone-type audio-frequency test instrument, the both hands of tester are liberated to a certain extent, then achieves the audio-frequency test that a tester just can complete cable, people from province is laborsaving.During use, tester can utilize the spring leaf at the tester back side to be stuck on waistband or pocket; Then test earphone is filled in ear; Subsequently, with separating the both hands of releasing, calibrating terminal being connected on the copper core of cable, namely completing the test of cable audio frequency.The utility model can allow work more convenient, operation of operating personnel more simply, not need two people to coordinate, and independently just can complete test job, substantially increases operating efficiency.
2, the utility model scientific structure design is reasonable, have easy to operate, economize that people is laborsaving, operating efficiency is high, be easy to the advantage that realizes, be a kind of earphone-type audio-frequency test instrument with higher innovation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view (omitting calibrating terminal and test earphone) of Fig. 1.
Reference numeral:
1-calibrating terminal, 2-wire, 3-mechanism for testing, 4-earphone plug-in opening, 5-test earphone, 6-mounting groove, 7-spring leaf.
Embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail.Following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of earphone-type audio-frequency test instrument, comprise mechanism for testing 3 and calibrating terminal 1, the audio-frequency test end of mechanism for testing is connected with two wires 2, a calibrating terminal is connected respectively in the end of two wires, its innovation is: on the control end of described mechanism for testing, be provided with earphone plug-in opening 4, this earphone plug-in opening is fitted with test earphone 5, is shaped with a mounting groove 6 at the back side of described mechanism for testing, in this mounting groove, be fitted with a spring leaf 7.
Described test earphone is PlayGear Stealth.
During use, tester can utilize the spring leaf at the tester back side to be stuck on waistband or pocket; Then test earphone is filled in ear; Subsequently, with separating the both hands of releasing, calibrating terminal being connected on the copper core of cable, namely completing the test of cable audio frequency.The utility model can allow work more convenient, operation of operating personnel more simply, not need two people to coordinate, and independently just can complete test job, substantially increases operating efficiency.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
