Abstract
This utility model relates to a kind of ignition coil, especially a kind of ignition coil.Clip is metal holder, it is arranged on the bottom of joint, joint clamped by clip, the afterbody of clip is provided with an annulus, contact tube is fixedly installed in annulus, other end ground connection, and housing is provided with insulating radiation plate, described joint is arranged on insulating radiation plate, and joint is isolated by insulating radiation version with surface of shell.When in use, once joint is breakdown for said structure, then high-tension electricity will be guided by metal holder and be derived by contact tube, do not interfere with other parts, it is greatly improved security performance, and fills water in the inside of contact tube, as cooling liquid, high-tension electricity passes when, instantaneous high-temperature will not be produced, and normal use when, also be able to help heat radiation, the stopper slot of an arc is set, not only increase area of dissipation, can also well fix the position of housing simultaneously.
Description
Technical field
This utility model relates to a kind of ignition coil, especially a kind of ignition coil.
Background technology
Two groups of coils, primary coil and secondary coil is had inside common ignition coil.Primary coil is with thicker enamel-covered wire, generally with the enamel-covered wire of 0.5-1 millimeter around about 200-500 circle;Secondary coil is with thinner enamel-covered wire, generally with the enamel-covered wire of 0.1 millimeter around about 15000-25000 circle.Primary coil one end and low-tension supply on car (+) couple, the other end couples with switching device (circuit breaker).Secondary coil one end couples with primary coil, and the other end couples output high-tension electricity with high-voltage line outfan.Why low tension on car can be become high voltage by ignition coil, is that primary coil is bigger than the turn ratio of secondary coil owing to there being the form identical with common transformer.But ignition coil working method is different with common transformer, the operating frequency of common transformer is fixing 50Hz, also known as Industrial Frequency Transformer, ignition coil then works with impulse form, can regard pulse transformer as, it is repeated energy storage and exoergic according to the rotating speed that electromotor is different with different frequencies.When primary coil switch power, along with the growth surrounding of electric current produces a magnetic field the strongest, iron core stores magnetic field energy;When switching device makes primary coil circuit disconnect, decaying rapidly in the magnetic field of primary coil, secondary coil will induce the highest voltage.The magnetic field disappearance speed of primary coil is the fastest, and the electric current that electric current disconnects moment is the biggest, and the turn ratio of two coils is the biggest, then the voltage that secondary coil induces is the highest.
But current and ignition coil is the most often punctured by instantaneous pressure, thus cause the phenomenon altered a little, there is potential safety hazard.
Utility model content
The purpose of this utility model is, it is provided that a kind of safety is high, fast ignition coil of lowering the temperature.
This utility model solves its technical problem and be the technical scheme is that a kind of ignition coil, including housing, housing is provided with four joints, characterized by further comprising conductive mechanism, conductive mechanism includes clip, contact tube, clip is metal holder, it is arranged on the bottom of joint, joint clamped by clip, and the afterbody of clip is provided with an annulus, and contact tube is fixedly installed in annulus, other end ground connection, housing is provided with insulating radiation plate, and described joint is arranged on insulating radiation plate, and joint is isolated by insulating radiation version with surface of shell.
Of the present utility model it is further arranged to: described contact tube inner hollow, in hollow space, fills cooling liquid.
Of the present utility model it is further arranged to: described cooling liquid is water.
Of the present utility model being further arranged to: be provided with the breach of an arc in the side of housing, the breach of arc constitutes a stopper slot.
When in use, once joint is breakdown for said structure, then high-tension electricity will be guided by metal holder and be derived by contact tube, do not interfere with other parts, it is greatly improved security performance, and fills water in the inside of contact tube, as cooling liquid, high-tension electricity passes when, instantaneous high-temperature will not be produced, and normal use when, also be able to help heat radiation, the stopper slot of an arc is set, not only increase area of dissipation, can also well fix the position of housing simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment；
The structural representation of Fig. 2 position the present embodiment contact tube.
Detailed description of the invention
Understand with reference to Fig. 1-2, this utility model one ignition coil, including housing 1, housing 1 is provided with four joints 11, also include conductive mechanism, conductive mechanism includes clip 2, contact tube 3, clip 2 is metal holder, it is arranged on the bottom of joint 11, joint 11 clamped by clip 2, the afterbody of clip 2 is provided with an annulus 21, contact tube 3 is fixedly installed in annulus 21, other end ground connection, housing 1 is provided with insulating radiation plate 12, described joint 11 is arranged on insulating radiation plate 12, joint 11 is isolated by insulating radiation version 12 with housing 1 surface, described contact tube 3 inner hollow, cooling liquid 31 is filled in hollow space, described cooling liquid 31 is water, the breach of an arc it is provided with in the side of housing 1, the breach of arc constitutes a stopper slot 13.
Obviously, above-described embodiment is only used to done citing is clearly described, and not restriction to embodiment.For the technical staff in described field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out or variation are still in protection domain of the present utility model.
