Abstract
The utility model relates to a circuit index gage, comprising a thermoplastic plastic external shell, a sensing coil, a circuit board, a light emitting diode, a resistance, a rectifying diode and wires. The index gage displays the work condition of elements of an electric heater by making use of the light emitting diode, when being used, wires cross the a central via hole of the index gage then are connected to the heating elements, when the heating elements work normally, the light emitting diode illuminates, when the heating elements have accidents, the light emitting diode extinguishes. The utility model is suitable to monitor the work condition of the electric heater, observe the mobile load, guide the phase lacking, monitor the motor operation and the like, which is a current index gage with easy operation, low cost and convenient observation.
Description
The utility model relates to Electron YuanJianJianCeZhuangZhi, specifically a kind of current indicator.
At present, on the loop of well heater, also there is not relevant device can indicate its duty, if will be to the detection of electric current deixis, testing tool commonly used be a reometer, but in actual mechanical process, the user is general, and whether the understanding circuit that only needs is normal, and need not detect the size of electric current, and reometer operates, and exists trouble is installed, contrast not strong, and weak point such as reometer complex structure, cost of manufacture height.
The purpose of this utility model is to develop a kind of, simple in structure, volume small and exquisite, cost are low, even make things convenient for the monitor staff whether to have electric current to pass through by also coming the directly monitoring circuit, thereby understand the current indicator whether the related electric element of well heater on whole loop is in normal operating conditions by the light on and off of light emitting diode at very little electric current.
Major technique content of the present utility model is, a kind of current indicator, constitute by thermoplastics shell, inductive coil, circuit board, light emitting diode, resistance, commutation diode, lead, it is characterized in that, the thermoplastics shell is made up of two symmetric parts, be respectively equipped with the groove of card circuit board, the central hole on the interior edge of band in the shell, be equipped with light emitting diode, resistance, commutation diode on the circuit board, along overcoat inductive coil is arranged in the central hole, the lead on the inductive coil links to each other with light emitting diode on the circuit board.
The utility model is compared the advanced part that is had and is with prior art, this current indicator, have simple in structure, simple installation, applied widely, observe easily, be easy to carry, characteristics such as cost is low, practicality, thereby overcome existing reometer complex structure, trouble has been installed, contrast not obvious, weak points such as cost height.
Description of drawings:
This figure is a utility model stereoscopic inner structure synoptic diagram;
Wherein, shell 1, inductive coil 2, lead 3, circuit board 4, light emitting diode 5, resistance 6, commutation diode 7, groove 8, central hole 9.
Below in conjunction with accompanying drawing the utility model is remake description further, thermoplastics shell 1 is made up of two symmetric parts, be respectively equipped with the groove 8 of card circuit board 4, the central hole 9 on the interior edge of band in the shell 1, be equipped with on the circuit board 4 in light emitting diode 5, resistance 6, commutation diode 7, the central hole 9 and inductive coil 2 arranged along overcoat, lead 3 on the inductive coil 2 links to each other with light emitting diode 5 on the circuit board 4, more than just constitute the utility model.
