Abstract
The utility model discloses a universal meter for illuminating a functional knob. The universal meter comprises a universal meter body, a protective sleeve, a meter probe and a measuring circuit board, and is characterized in that the functional knob is arranged in front of the universal meter body; a light-emitting diode (LED) light source which is arranged on the measuring circuit board is arranged under the functional knob; and a transparent light guiding piece and two refracting surfaces are arranged on the functional knob. By the universal meter, measuring ranges and functional gears at the periphery of the functional knob on a control panel are illuminated under the occasion of insufficient light rays; and the universal meter is convenient to use and safe, and the defect that the positions of selection functions are indistinct when the universal meter is used for measuring in the dark environment by users is overcome, so that the users can perform measuring operation conveniently, safely and accurately under the occasions of low visibility.
Description
Technical field
The utility model relates to the multimeter field, relates in particular to a kind of function knob illumination multimeter.
Background technology
Multimeter, as a kind of electronic measuring instrument, is widely used in the electric parameters such as measuring voltage, electric current, resistance, electric capacity, electricity frequency.Current digital multimeter comprises multimeter body, protective sleeve, test pencil etc., and the multimeter body is provided with shell, display screen, control mainboard, function knob etc.Function knob is the critical piece in control panel, and the user can select its project that will measure and range by this function knob, and display screen is used for the display measurement result.Digital multimeter is flexible when metering circuit, electrical equipment, parameter is intuitively by extensive practicality.But because multimeter is very inconvenient in the occasion use of insufficient light at present, as brought selection function and range very inconvenient in the place in low visibility, for example: the user can be when measuring voltage mistake selection the measurement function of current, and the selection mistake of range, this may cause the damage of multimeter even to injure the user.
The utility model content
In view of this, technical problem to be solved in the utility model is: provide a kind of and can under the occasion of insufficient light, illuminate control panel function knob range and function shelves on every side, easy to use, safe, when the solution user uses multimeter to measure under dark surrounds, the selection function position does not see the defect of Chu.
In order to achieve the above object, the utility model adopts following technical scheme to realize: a kind of function knob illumination multimeter, comprise multimeter body, protective jacket, test pencil, testing circuit board, it is characterized in that: described multimeter body front is provided with function knob, and a LED light source be arranged on described testing circuit board is arranged under function knob.
Described function knob is provided with the transparent light guide part.
Described function knob is provided with two planes of refraction.
The light that LED sends, by transparent light guide part and being used in conjunction with of two planes of refraction that sets special angle, emits from the top of function knob and two lamps of side respectively, illuminates function and range zone around function knob.Make the operation of measurement accurately that the occasion under low visibility can be convenient and safe the user.
As shown from the above technical solution, the beneficial effects of the utility model are:
Illuminate control panel function knob range and function shelves on every side under the occasion of insufficient light, easy to use, safe, when the solution user uses multimeter to measure under dark surrounds, the selection function position does not see the defect of Chu.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model function knob structural scheme of mechanism;
Fig. 3 is the utility model function knob vertical view schematic diagram;
Fig. 4 is that the utility model function knob A-A is to cut-open view.
Embodiment
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing.
Refer to Fig. 1 to Fig. 4, the utility model provides a kind of function knob illumination multimeter, comprise multimeter body 1, protective jacket 2, test pencil 3, testing circuit board, it is characterized in that: described multimeter body 1 front is provided with function knob 4, and a LED light source 7 be arranged on described testing circuit board is arranged under function knob 4.
Described function knob 4 is provided with transparent light guide part 8.Described function knob 4 is provided with two planes of refraction (9,10).The light that LED 7 sends is used in conjunction with by transparent light guide part 8 and two planes of refraction (9,10) that set special angle, from top lamp 5 and the side lamp 6 of function knob 4, emits respectively, illuminates function and range zone around function knob 4.Make the operation of measurement accurately that the occasion under low visibility can be convenient and safe the user.
The foregoing is only better possible embodiments of the present utility model, not in order to limit to the scope of the claims of the present utility model, therefore the equivalent structure that all utilization the utility model instructionss and accompanying drawing content are done changes, all in like manner be included in scope of the present utility model.
