Abstract
The utility model discloses a loop on/off detection device comprising a housing. A power source, a switch, a signal lamp, a buzzer and two meter pen jacks are arranged on the housing, the signal lamp is in parallel connection with the buzzer, one end of the portion formed by the parallel connection of the signal lamp and the buzzer is connected with one meter pen jack, and the other end of the portion is connected with one end of the switch, the other end of the switch is connected with one end of the power source, and the other end of the power source is connected with the other meter pen jack. Compared with the prior art, a present circuit is improved according to the utility model, so that the buzzer and the indicating lamp can simultaneously work during a loop on/off detection process, and an operator can determine on/off states of equipment to be detected more conveniently; the detection device is protected by the housing, so that the reliability and the safety of the detection device are effectively ensured, and the operator can conveniently operate, use and keep the detection device; and the detection device is simple in structure, is of low cost and is practical.
Description
Technical field
The utility model relates to the detection field of circuit loop, particularly relates to a kind of loop switching detection device.
Background technology
In electronic equipment production scene, often need to carry out loop break-make detection to the circuit board of having produced or electronic equipment, but the processing environment of workshop generally all can be very noisy.And generally carry out now this work, all adopt digital multimeter, but the buzzer that digital multimeter itself carries is very little, in noisy environment, is easy to ignore to fall this sound, can cause operator to judge by accident equipment under test disconnected.
In order to address the above problem, some operators design a kind of for the easy device of test loop break-make, only need in loop, add a powerful hummer just can finish the work, but this design is because simple in structure, many times, only in order to meet needs self manufacture for the moment, can not meet large-scale industrial requirement.
Utility model content
In order to solve above-mentioned existing issue, the utility model proposes a kind of loop switching detection device, by the two ends of two test pencils contact equipment under tests on this device, according to the whether conducting of the reaction and judgement equipment under test loop of pick-up unit.
The concrete technical scheme that the utility model adopts is:
A kind of loop switching detection device, described device comprises shell, on described shell, be provided with power supply, switch, signal lamp, hummer and two test pencil jacks, described signal lamp and hummer are connected in parallel, one end after parallel connection is connected on a test pencil jack, the other end after parallel connection is connected on one end of switch, and the other end of switch is connected to one end of power supply, and the other end of power supply is connected on another test pencil jack.
In technique scheme, the two ends of described power supply are provided with jack interface, and described jack interface is arranged on shell.
In technique scheme, described power supply is rechargeable battery.
In technique scheme, described jack interface is charging inlet.
In technique scheme, described signal lamp is light emitting diode.
The utility model compared with prior art, by existing circuit is being improved, can accomplish when carrying out loop break-make detection, hummer and pilot lamp are worked simultaneously, the break-make situation that more can useful operating personnel judges equipment under test, simultaneously because adopt pick-up unit guaranteed with shell, more effective reliable, the security that has guaranteed pick-up unit, and handled easily person operation, use, this pick-up unit of keeping, this structure of the detecting device is simple, cost is low, practical.
Accompanying drawing explanation
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 position circuit diagram of the present utility model;
Wherein: BT is that accumulator, D1 and D2 are that light emitting diode, F are that hummer, J are that socket, K are that switch, R are that current-limiting resistance, 1 and 2 is test pencil jack.
Embodiment
Disclosed all features in this instructions, except mutually exclusive feature, all can combine by any way.
As shown in Figure 1, for circuit diagram of the present utility model, in circuit, comprise two light emitting diodes (D1 and D2), the light emitting diode current-limiting resistance R that connects is on one side excessive for controlling electric current, a hummer F in parallel with light emitting diode, both latter one section in parallel be connected on test pencil jack 1, other end connecting valve K after parallel connection, the other end of K switch connects one end of accumulator BT, the other end of accumulator BT is connected on test pencil jack 2, company's section at accumulator BT is connected with socket J, and socket J is charging socket.
In actual use, the test pencil of universal digital table is inserted in test pencil jack 1 and 2, toggle switch K, make internal circuit conducting, with the two ends of test pencil, go to contact two measured points of equipment under test, if hummer and light emitting diode work, represent that pick-up unit and tested device form loop conducting, tested device loop is path; If light emitting diode and hummer are not worked, represent the circuit breaker in tested device, tested device need to be keeped in repair.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
