Plain edition central electrode and lateral electrode mostly use nickel, nickel alloy is made, in the long-term ignition operation of spark plug
Afterwards, it is susceptible to burning phenomenon, causes durable performance to be affected, and cold-start performance is also bad.Therefore occur in recent years expensive
Metal sparks plug welds the noble metals such as higher melting-point platinum, iridium on central electrode and lateral electrode, to effectively improve spark plug
Ignition performance and high temperature resistance, existing spark-plug side electrode end by 90 degree of bendings close to center electrode end, but the knot
Structure is unfavorable for electric current is made to pass through iridium metals generating strong spark.
Utility model content
To solve the above-mentioned problems, a kind of novel spark generating strong spark by iraurite convenient for sparking-plug electrode is provided
Plug, the utility model devise a kind of iridium spark plug.
The specific technical solution that the utility model is taken is：A kind of iridium spark plug, including main body, central electrode and side
Electrode, central electrode and lateral electrode, which correspond to, stretches out main body end face, and lateral electrode extends forward and connect U-shaped bending part, the U-shaped folding
Center electrode end is directed toward in turn of bilge end, and lateral electrode end is equipped with the iraurite of corresponding central electrode.
Preferably, lateral electrode end is connected with spherical iraurite, and center electrode end is equipped with the hemisphere of corresponding lateral electrode
Shape iraurite protrusion.
Preferably, lateral electrode end is equipped with hemisphere iraurite cover body；Center electrode end is equipped with the half of corresponding lateral electrode
Spherical iraurite protrusion.
Further, lateral electrode or central electrode end are inlayed or be welded on to iraurite.
Advantageous effects：It solves the problems, such as that traditional double-needle type spark-plug side electrode needle is easy to fall off, solves and making
The spacing of central electrode and lateral electrode adjusts problem when making spark plug, effectively saves iraurite material.

The hemispherical iraurite protrusion of 1 main body, 2 central electrodes, 3 lateral electrodes, 2a, the spherical iraurites of 3a, 3b hemisphere iraurite covers in figure
Body.
Specific implementation mode
A kind of iridium spark plug, referring to Fig. 1：Including main body 1, central electrode 2 and lateral electrode 3, central electrode 2 and lateral electrode
3 correspond to 1 end face of stretching main body, and lateral electrode 3 extends forward and connect U-shaped bending part, electrocardio during U-shaped bending part end is directed toward
2 end of pole, 3 end of lateral electrode are equipped with the iraurite of corresponding central electrode 2.
3 end of lateral electrode is connected with spherical iraurite 3a, and 2 end of central electrode is equipped with the hemispherical iraurite of corresponding lateral electrode 3
Raised 2a.
It is connected with spherical iraurite 3a in lateral electrode 3, central electrode 2 is directed toward by spherical iraurite 3a, lateral electrode 3 passes through U-shaped
Bending part connects spherical iraurite 3a, ensures that 3 main body 1 of lateral electrode far from central electrode 2, avoids 2 main body 1 of central electrode and lateral electrode
It is powered between 3 main bodys 1 and generates electric spark.
3 end of lateral electrode is equipped with hemisphere iraurite cover body 3b；2 end of central electrode is equipped with the hemispherical iridium of corresponding lateral electrode 3
Gold bump 2a.Hemisphere iraurite cover body 3b internal diameters match with hemispherical iraurite protrusion 2a outer diameters.
2 end of lateral electrode 3 or central electrode is inlayed or be welded on to iraurite.
It is connected with cover body shape iraurite in lateral electrode 3, central electrode 2 is directed toward by cover body shape iraurite, lateral electrode 3 passes through U-shaped
Bending part connects spherical iraurite, ensures that 3 main body 1 of lateral electrode far from central electrode 2, avoids 2 main body 1 of central electrode and lateral electrode 3
It is powered between main body 1 and generates electric spark.Cover body shape iraurite cover increases by two to the hemispherical iraurite protrusion 2a of 2 end of central electrode
Person's relative area ensures the sparking rate of sparking-plug electrode.
Solve the problems, such as that traditional double-needle type spark-plug side electrode needle is easy to fall off using U-shaped bending part simultaneously, it can be intuitive
The distance measurement that central electrode and lateral electrode are carried out by U-shaped bending part, solve when manufacture spark plug central electrode with
The spacing of lateral electrode adjusts problem,
Lateral electrode 3 is directed toward central electrode 2 by connecting U-shaped bending part, ensures that iraurite and 2 spacing of central electrode are nearest, from
And it is iraurite that plug ignition point, which is effectively ensured, improves ignition effectiveness, and compared with general spark plug, iraurite central electrode 2 and spy
The lateral electrode 3 of different shape realizes outstanding ignition performance, reduce in the case where requiring voltage relatively high engine without
The situation that method starts.
