Abstract

An acousto-optic circuit detector comprises a power supply and a buzzer, which is characterized in that a capacitor is connected to the buzzer in parallel, the power supply, the buzzer and the capacitor are arranged in a host box, the host box is externally connected with a detection pen, and a light emitting diode is arranged on the detection pen. The utility model is convenient for carrying and maintenance, and a 9-volt battery is utilized as the power supply of the acousto-optic circuit detector, which guarantees small volume and durability. The light emitting diode utilized as a visual display portion is more intuitive while being mounted on the detection pen, thereby coils in the circuit can be effectively determined so as to avoid misjudgment, in addition, the micro-buzzer is utilized as acoustic indication implementation so as to avoid external noise influence and increase the testing quality, further, the shock problem to the diode from the circuit switched on or off can be solved by the capacitor, while for remote use, a double-indication test system formed by combining two acousto-optic circuit detectors, adjusting polarities of the capacitors to be opposite, and connecting common terminals can inform both testers of the detection conditions, and an assistant massager standing between both testers for message transmission is not required, thereby saving labor.

Description

Acousto-optic wireline inspection instrument

Technical field

The utility model belongs to electric wiring detection technique field, especially relates to a kind of acousto-optic wireline inspection instrument.

Background technology

Existing school the Line tool is to be composed in series by 4 No. 1 dry cells of joint and a hummer mostly, or be composed in series by 4 joint No. 1 dry cells and miniature bulbs, volume is big, inconvenience is carried, whether the former can't not hear conducting at all when ambient noise is excessive, two kinds of school the Line tools can't differentiate whether gone here and there coil in the circuit at all, very easily cause erroneous judgement disconnected, cause detecting inaccurate, and these two kinds of school the Line tools all are at one end to be provided with the display part, sometimes the people who passes on a message that needs during remote the use stand again in the centre carries out the conduction of information and just can finish test, lavishes labor on.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of saving manpower, improves the acousto-optic wireline inspection instrument that detects quality, and this detector can be judged whether coil is arranged in the circuit, avoid the influence of ambient noise simultaneously.

For solving the problems of the technologies described above, the utility model provides a kind of acousto-optic wireline inspection instrument, comprises power supply, hummer, it is characterized in that: hummer is parallel with electric capacity, power supply, hummer and electric capacity are located in the host box, and host box is connected with detecting pen outward, and detecting pen is provided with light emitting diode.

The utility model is easy to carry, is easy to maintenance; Adopt the 9V battery as detecting power supply, its volume is small and exquisite and more durable; Utilize the more responsive characteristic of led current reaction as the Visual Display part, be contained on the test pen more intuitively, can effectively differentiate and whether go here and there coil in the circuit, break thereby stop erroneous judgement; Adopt miniature hummer to replenish simultaneously, avoid the influence of ambient noise, improve and detect quality as audible indication; The shock problem that when utilizing electric capacity solution circuit to be switched on or switched off again diode is caused; During remote the use, with the combination of two covering devices, it is opposite to adjust electric capacity polarity, public end connection just constitutes the two indication of cover test macros, make the test both sides can learn detection case simultaneously, the people who passes on a message that so just needn't stand again in the centre carries out the conduction of information, saves manpower.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation that two cover instrument combination is used when using at a distance.

Embodiment

With reference to Fig. 1, the utility model comprises power supply 1, hummer 2, and hummer 2 is parallel with electric capacity 3, and power supply 1, hummer 2 and electric capacity 3 are located in the host box 4, is connected with detecting pen 5 outside the host box 4, and detecting pen 5 is provided with light emitting diode 6.

With reference to Fig. 2, form the two indication of cover test macro by two cover instrument combination, can when Distance Test, use, make the test both sides can learn detection case simultaneously, the people who passes on a message that so just needn't stand again in the centre carries out the conduction of information, and for preventing that two overlap instruments and occur line power idle phenomenon of playing a reversed role after continuous, therefore when design, make the polarity in the two cover instruments opposite, so only need directly to connect two system share ends, power supply just will not take place play a reversed role, do not need artificial adjustment.

Claims (1)

1, a kind of acousto-optic wireline inspection instrument comprises power supply, hummer, and it is characterized in that: hummer is parallel with electric capacity, and power supply, hummer and electric capacity are located in the host box, and host box is connected with detecting pen outward, and detecting pen is provided with light emitting diode.
