Abstract
The utility model relates to a three-pin capacitor convenient for distinguishing pins, which comprises a cover plate, wherein the cover plate is provided with a fan capacitor pin, a press capacitor pin and a common pin, the fan capacitor pin comprises a first metal welding piece, the first metal welding piece is fixed on the cover plate through a first insulating base, the press capacitor pin comprises three second metal welding pieces, the second metal welding pieces are fixed on the cover plate through second insulating bases respectively, the common pin comprises four third metal welding pieces, and the third metal welding pieces are fixed on the cover plate through third insulating bases respectively. By means of arranging the first metal welding piece on the fan capacitor pin, arranging three second metal welding pieces on the press capacitor pin and arranging four third metal welding pieces on the common pin, the type of each pin is judged through different numbers of the metal welding pieces, thereby being convenient, efficient and effective, and convenient to distinguish, and effectively avoids occurrence of great potential safety hazards caused by mistake connection.
Description
Technical field
The utility model relates to capacitor technology field, relates in particular to the tripod capacitor of being convenient to distinguish pin.
Background technology
Capacitor is commonly referred to electric capacity, and electric capacity is also called " capacitance ", refers to the electric charge reserves under given potential difference, is designated as C, and international unit is farad (F).In general, electric charge is understood stressed and is moved in electric field, has had medium between conductor, has hindered electric charge move and make charge accumulation on conductor, causes the accumulation of electric charge to store, and the quantity of electric charge of storage is called electric capacity.Electric capacity is one of a large amount of electronic components that use in electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.
Tripod electric capacity is that the electric capacity of two perhaps poor capacitances such as grade encapsulates with shell, because there being a pin, is public pin, therefore be three pins, tripod electric capacity can be done parallel connection, series connection, the use of discrete double volume, just conventional this type of electric capacity of common single-phase double volume motor.
In prior art, three general moulding of pin on the cover plate of tripod electric capacity are all identical, and sometimes common pin is slightly different, and other two pins are identical, be not easily distinguishable, sometimes people usually mark below different pins, but in the situation of long term wear, mark tends to see fuzzy, even disappear, be not easily distinguishable, the in the situation that of wrong, be easy to cause the generation of potential safety hazard.
Utility model content
In view of this, be necessary to provide a kind of safety, and be convenient to distinguish the tripod capacitor of pin.
The utility model is to realize like this, be convenient to distinguish the tripod capacitor of pin, comprise cover plate, cover plate is provided with blower fan capacitor pin, press capacitor pin and common pin, described blower fan capacitor pin comprises a first metal welding fitting, described the first metal welding fitting is fixing on the cover board by the first insulating base, described press capacitor pin comprises three the second metal welding fittings, described the second metal welding fitting is fixing on the cover board by the second insulating base, described common pin comprises four the 3rd metal welding fittings, described the 3rd metal welding fitting is fixing on the cover board by the 3rd insulating base.
Further, described cover plate is provided with for the scolding tin hole through electric wire.
The advantage that the utility model provides is convenient to distinguish the tripod capacitor of pin is: by a first metal welding fitting being set on blower fan capacitor pin, three the second metal welding fittings are set on press capacitor pin and four the 3rd metal welding fittings being set in common pin, by the metal welding fitting of varying number, judge the type of each pin, convenient and swift effective, be convenient to distinguish, effectively avoid the generation of the major safety risks that cause because of wrong.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is convenient to distinguish the tripod capacitor of pin.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation that the utility model is convenient to distinguish the tripod capacitor of pin.
The described tripod capacitor of being convenient to distinguish pin, comprise cover plate 10, cover plate 10 is provided with blower fan capacitor pin 20, press capacitor pin 30 and common pin 40, described blower fan capacitor pin 20 comprises a first metal welding fitting 21, described the first metal welding fitting 21 is fixed on cover plate 10 by the first insulating base 50, described press capacitor pin 30 comprises three the second metal welding fittings 31, described the second metal welding fitting 31 is fixed on cover plate 10 by the second insulating base 60, described common pin 40 comprises four the 3rd metal welding fittings 41, described the 3rd metal welding fitting 41 is fixed on cover plate 10 by the 3rd insulating base 70.
Described cover plate 10 is provided with for the scolding tin hole 80 through electric wire.
In practical operation, also can be on described cover plate 10 corresponding blower fan capacitor pin 20, press capacitor pin 30 and common pin 40 steel seal projection that " FAN " shape, " HERM " shape and " C " shape be set respectively strengthen being convenient to distinguishing.
By a first metal welding fitting 21 being set on blower fan capacitor pin 20, three the second metal welding fittings 31 are set on press capacitor pin 30 and four the 3rd metal welding fittings 41 being set in common pin 40, by the metal welding fitting of varying number, judge the type of each pin, convenient and swift effective, be convenient to distinguish, effectively avoid the generation of the major safety risks that cause because of wrong.
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 range of the present utility model.
