The simple wire on-off detection device can accurately detect the connection and disconnection of the wires, simultaneously is simple in structure and convenient to use, and can be widely applied to checking of electronic control cabinet, wire inspection of automobiles and wire calibration of cables.
Description
Technical field
The utility model relates to a kind of Simple lead switching detection device, belongs to electronic technology field.
Background technology
At present, the wire break-make testing tool commonly used of electrical technology personnel is multimeter.Gear is transferred to the diode shelves, two test pencils respectively with tested wire two end in contact, according to the break-make of the reaction and judgement wire of hummer.But, the method used testing tool-the multimeter cost is higher and may cause erroneous judgement owing to misoperation.
The utility model content
For the problems referred to above, the utility model provides a kind of Simple lead switching detection device, can detect accurately the break-make of wire, and is simple in structure simultaneously, easy to operate.
In order to realize above-mentioned functions, the utility model adopts following technical solution: a kind of Simple lead switching detection device, by power supply 1, wire 2, resistance 3, light emitting diode 4, hummer 5 forms, connect with resistance 3 after light emitting diode 4, hummer 5 parallel connections, power supply 1 one side main lines disconnect, and the main line is drawn two wires 2 and connect tested wire two ends.
Described power supply 1 is dry cell, and described hummer 5 is the piezoelectric type active buzzer.
The beneficial effects of the utility model: can detect accurately the break-make of wire, simple in structure simultaneously, easy to operate, can be widely used in the school line of the electrical control cabinet inspection of line, automobile line inspection, cable etc.
Description of drawings
Fig. 1 is circuit connection diagram of the present utility model;
Among the figure: 1-power supply, 2-wire, 3-resistance, 4-light emitting diode, 5-hummer.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, understands to make things convenient for the technician.
As shown in Figure 1: a kind of Simple lead switching detection device, by power supply 1, wire 2, resistance 3, light emitting diode 4, hummer 5 forms, connect with resistance 3 after light emitting diode 4, hummer 5 parallel connections, power supply 1 one side main lines disconnect, and the main line is drawn two wires 2 and connect tested wire two ends.
Described power supply 1 is dry cell, not only cheaply but also convenient the purchase.
Described hummer 5 is the piezoelectric type active buzzer, and advantage is the inner band of piezoelectric type active buzzer concussion source, can sound once energising.
Connect with resistance 3 after described light emitting diode 4 and hummer 5 are in parallel, install in use procedure at this, if light emitting diode 4 and hummer 5 have side damage, can judge whether conducting of wire according to the opposing party's state.Simultaneously, also can under different external conditions, use, if the operating environment noise is large, can judge whether conducting of wire according to the state of light emitting diode 4 so; If operating environment illumination is strong, can judge whether conducting of wire according to the state of hummer 5 so.
The utility model can detect the break-make of wire accurately, and is simple in structure simultaneously, easy to operate, can be widely used in the school line of the electrical control cabinet inspection of line, automobile line inspection, cable etc.
The utility model describes by accompanying drawing, in the situation that does not break away from the utility model scope, can also carry out various conversion and be equal to replacement the utility model patent, therefore, the utility model patent is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall in the utility model Patent right requirement scope.
