Abstract
A portable wire calibrating device comprises a shell, the batteries, a light emitting diode and a buzzer; the batteries are installed inside the shell and the light emitting diode and the buzzer are installed on the shell and connected with the batteries. It is characterized in that the output ends of the light emitting diode and the buzzer are linked together with the plugging hole installed on the shell.
Description
Technical field
The utility model relates to a kind of school line apparatus, and especially a kind of sound and light alarm that circuits such as electrical cable, telecommunication, electronic circuit are detected shows the school line apparatus.
Background technology
The general school line lamp of Shi Yonging mainly is made of the crocodile clip of battery, small electric bulb and output terminal and insulated conductor etc.Two school line lamps that polarity is identical commonly used are clamped the common port at tested cable two respectively during use with the crocodile clip of one of output terminal, and another output terminal with two school line lamps links to each other with tested cable two ends respectively again, realize the detection to this cable core.Though simple in structure, crocodile clip very easily damages the insulation course that connects lead and causes fault such as short circuit.In addition, because the detection of existing correcting line machine demonstration is not obvious, the necessary high concentration of notice not only wasted time and energy when the staff operated, and labour intensity is big, and work efficiency is low.Therefore, be necessary prior art is improved.
Summary of the invention
For overcoming the fragile line insulation layer that prior art exists, it is not obvious to detect demonstration, requires staff's notice high concentration, waste time and energy, work efficiency is low, carries inconvenience, the big deficiency that waits of labour intensity, the utility model provides a kind of portable school line apparatus.
The utility model is realized by following technical proposal: a kind of portable school line apparatus, comprise housing, be installed in the battery in the housing, and be installed on the housing and light emitting diode that links to each other with battery and hummer, it is characterized in that respectively the output terminal that links to each other with hummer with light emitting diode links to each other with spliced eye on being installed in housing.
Be provided with switch between described battery and the output terminal and between light emitting diode and the output terminal, detect the loop so that constitute independent sounding as required, be used for detecting daytime, perhaps sounding, luminous loop are used for detecting night.
The utility model compared with prior art has following advantage and effect: adopt such scheme, can be with battery, lead is encapsulated in the housing, light emitting diode and hummer are fixed on position comparatively showy on the housing, be arranged on spliced eye on the housing and be easy to the position that tested cable socket inserts, operating personnel have fundamentally been solved because of the notice high concentration problem of " fatigue " too, both be convenient for carrying and operated, can realize fast detecting again, effectively improved work efficiency, in addition, the setting of switch, can select independent sounding to detect as required, perhaps sounding, luminous detection is applicable to and detects at daytime or night, makes this school line apparatus versatile and flexible and energy-conservation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the circuit structure diagram of the utility model;
Fig. 3 is another circuit structure diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Battery 2 is installed in the housing 1, and light emitting diode 4 and hummer 5 are installed on the front plate of housing 1, so that show detection signal intuitively, spliced eye 3 is installed in the side of housing 1, so that the plug p-wire, as Fig. 1.The positive and negative electrode of battery 1 connects hummer 5 and light emitting diode 4 respectively, and the output terminal 6,7 that links to each other with light emitting diode 4 with hummer 5 is electrically connected with corresponding spliced eye 3, as Fig. 2.Between the positive pole of battery 1 and output terminal 7, be connected with switch 8, between light emitting diode 4 and output terminal 7, be connected with switch 9, so that select independent sounding to detect as required, perhaps sounding, luminous detection.
Claims (2)
1, a kind of portable school line apparatus, comprise housing, be installed in the battery in the housing, and be installed on the housing and light emitting diode that links to each other with battery and hummer, it is characterized in that respectively the output terminal that links to each other with hummer with light emitting diode links to each other with spliced eye on being installed in housing.
2, portable school according to claim 1 line apparatus is characterized in that being provided with switch between described battery and the output terminal and between light emitting diode and the output terminal.
