Abstract
The utility model relates to an on-off-indicating unit for electric circuit which is a minitype simple indicating unit and is used to measure whether two points in the circuit are communicated or whether conducting wires are communicated. The utility model is mainly composed of a small-size battery, an LED, a testing probe, etc., has the advantages of small volume, power consumption saving, etc. and can be widely used in the switch electric unit industry, the electrical installation industry, the maintenance industry, etc.
Description
The utility model is the miniature simple and easy indicator of certain 2 whether communicate (lead communicates) in the metering circuit.
Now, in the work such as the secondary distribution of device for switching and electric installation and maintenance, usually need from several leads, to detect required one, or measure at certain 2 and whether communicate.Such as in the secondary distribution of switch electric utility, usually need from a branch of lead, to detect of the corresponding label of certain root lead, promptly on some the end of a thread of an end of a bunch, put on mark head " 102 " number, (according to the channel number of electrical equipment), just need find out at the other end of this bunch is with it other end with single line, then, put on identical circuit numbers, receive on the desired position,, use inconvenient on the one hand if adopt multimeter to measure; On the other hand, enterprise is general unlikely is equipped with a multimeter (even be equipped with, the workman also not necessarily reaches the level that everyone can use) for each first lineman people.Then often volume is big to adopt common battery bulb series process, and use of power consumption carried inconvenience (when adopting this method, because the about 300mA of bulb power consumption mostly adopts the large size battery) more.
The purpose of this utility model is to overcome the multimeter method, and the shortcoming of battery bulb method makes it to reduce volume, reduces power consumption, uses easy to carry.
The utility model is achieved in that the connecting and disconnecting of the circuit indicator is made up of compact battery and light emitting diode etc., and battery is loaded on the battery tube.Gauge tap is arranged on tube, and the front end of tube is equipped with light emitting diode and measuring sonde, and a lead is drawn from jack in the rear end, conductor wire end is connected to crocodile clip, clamps the end of a thread of required numbering during use with crocodile clip, touches corresponding the end of a thread with measuring sonde, at this moment, light emitting diode is just shinny.
Advantage of the present utility model: adopt this device, volume is small and exquisite, and is easy to carry, and common bulb (miniature bulb that torch is used) is power consumption 300mA approximately, and the light emitting diode power consumption 10mA that only has an appointment), thereby reduced power consumption (promptly having prolonged the serviceable life of battery).
The concrete structure of utility model is provided by following embodiment.
Fig. 1 is the electrical schematic diagram of this device, and Fig. 2 is the profile synoptic diagram of this device.At figure (among Fig. 1 and Fig. 2), (1) is measuring sonde, and (2) are light emitting diode, and (3) are current-limiting resistance, (4) be gauge tap, (5) are battery, and (6) are spring, and (7) are jack, (8) be plug, (9) for connecting lead, (10) are crocodile clip.
Common large size battery capacity is 4Ah, and No. 5 battery capacities are 0.5Ah.But the about 10mA of light emitting diode power consumption, and the about 300mA of bulb power consumption.So the battery of this device still is (0.5/10)/(4/300)=3.75 times in battery serviceable life of battery bulb method serviceable life.In the device, resistance plays metering function, gets about 82 Ω.For preventing not time spent short circuit, on the battery tube, be provided with switch (4), for ease of using, be provided with jack (7) and plug (8) in the end of battery tube.Clamp the end of a thread of required numbering with crocodile clip (10) during use, get final product with probe (1) searching then.The shinny degree of light emitting diode (2) can satisfy routine request, and as will prevent strong illumination the time, the brightness of light emitting diode (2) reduces relatively, the transparent body of clamping light emitting diode (2) can be blocked some, only exposes a wicket.
Claims (2)
1, the miniature simple and easy indicator that is used for metering circuit whether communicate (lead communicates) at 2 is characterized in that being made up of compact battery and light emitting diode.
2, indicator as claimed in claim 1 is characterized in that: gauge tap and jack are housed on this indicator, and gauge tap can be shut in time spent not, to prevent the short circuit voluntarily of this indicator; Jack can make measures the lead grafting conveniently.
