The device comprises a shell (1), a battery (2), an indicating lamp (3) and a probe jack (10), wherein one end of the shell (1) is provided with a slide block (4), a detection probe (6) and a slide block (5) are arranged on the slide block (4), a detection probe (7) is arranged on the slide block (5), the slide block (4) can move up and down along the shell, and the slide block (5) can move side to side along the slide block (4). Compared with the prior art, the device can conveniently detect polarity of diodes with different specifications, providing convenience for electronic enthusiasts and circuit maintenance persons.
Description
Technical field
The utility model relates to a kind of pick-up unit of electronic component, and more particularly, it relates to a kind of device that detects diode polarity.
Background technology
At present, the polarity of diode generally can be determined by the resemblance of diode itself, but because the encapsulation problem, causes the indicated polarity of the polarity of some diodes and its resemblance and do not meet; The pin of the diode that removes from circuit is irregular, more difficultly determines its polarity.At present, the device of the testing circuit that electrophile and maintenance circuit personnel are used is a multimeter, but aspect detection diode polarity, multimeter carries inconvenience; Some diode is small-sized, and the probe of multimeter can not detect.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of easy to carry and can detect the device of the diode polarity of multiple different size.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of diode polarity pick-up unit comprises shell (1), battery (2), pilot lamp (3), probe jack (10); One end of shell (1) is provided with slide block (4); Slide block (4) is provided with detector probe (6), slide block (5); Slide block (5) is provided with detector probe (7).Slide block (4) can move up and down along the relative battery of shell; Slide block (5) can be along slide block (4) slide block (6) side-to-side movement relatively.
Compared with prior art, the beneficial effects of the utility model are: a kind of device of very convenient detection diode polarity is provided, and can have detected the polarity of the diode of various different sizes.For electrophile and maintenance circuit personnel provide convenience.
Description of drawings
Fig. 1 is a kind of structural drawing of diode polarity pick-up unit;
Fig. 2 is a kind of circuit diagram of diode polarity pick-up unit.
Among the figure: shell 1, battery 2, pilot lamp 3, slide block 4, slide block 5, detector probe 6, detector probe 7, electric capacity 8, divider resistance 9, probe jack 10
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of diode polarity pick-up unit comprises shell (1), battery (2), pilot lamp (3), probe jack (10).Battery can use No. 5 batteries or No. 7 batteries on the market, also can use button cell; The voltage of battery is 1.3V～1.5V.
One end of shell (1) is provided with slide block (4); Slide block (4) is provided with detector probe (6), slide block (5); Slide block (5) is provided with detector probe (7).Slide block (4) can move up and down along shell, and slide block (5) also stretches out in shell or the withdrawal shell thereupon, thus protection detector probe (6) and detector probe (7).Slide block [5] can be along slide block (4) side-to-side movement, thereby change the distance between detector probe (6) and the detector probe (7), so just can detect the polarity of the diode of various different sizes with this diode detection device.
As shown in Figure 2, detect the polarity chron of diode with this diode polarity pick-up unit, detector probe (6) connects an end of diode, and detector probe (7) connects the other end of diode, if pilot lamp (3) is bright, then that end of being connect of detector probe (6) is the positive pole of diode; If pilot lamp (3) does not work, the two poles of the earth of the diode of turning round, detection gets final product once more.If detect pilot lamp (3) and all do not work for twice, then might damage by this diode.
In addition, can also adjust distance between the detector probe by slide block (5), and then detect the polarity of diode according to the size of diode.
Claims (1)
1. diode polarity pick-up unit, comprise shell, battery, pilot lamp, probe jack, it is characterized in that, one end of described shell (1) is provided with slide block (4), described slide block (4) is provided with detector probe (6), slide block (5), and described slide block (5) is provided with detector probe (7); Described slide block (4) can move along the relative battery of shell, and described slide block (5) can be along slide block (4) detector probe (6) motion relatively.
