Abstract
The invention discloses a spark plug. The spark plug comprises a center electrode and a side electrode. The center electrode is composed of a straight rod and a disc at a bottom end, and the straight rod is fixedly connected with the center of the disc; the side electrode is in the shape of a circular ring, and the disc is arranged at the circle center of the side electrode; and the disc is made of an alloy which is composed of 60-98% of iridium and 2 to 40% of chromium. According to the invention, the top end of the center electrode is arranged to be in the shape of a disc, and the electrode is correspondingly arranged to be in the shape of a circular ring, so that the discharge area is increased, and the discharge effects are improved; and at the same time, the circular ring-shaped side electrode reduces the influence exerted a carbon formation phenomenon on the use of the spark plug, and relatively prolongs the service life of the spark plug.
Description
Technical field
The present invention relates to auto parts machinery technical field, especially a kind of spark plug.
Background technology
Spark plug is the important accessory in automobile engine, existing conventional spark plug basic structure is all sheathed metal shell outside insulator, and central electrode is set in insulator, and metal shell connects lateral electrode, two electrodes are close at spark plug tip place, to form sparking electrode pair.Conventional lateral electrode is L-type structure, and horizontal segment centre is just to central electrode, this simple in structure easy to use, but easily on electrode, produces carbon distribution, causes useful life short, affects discharge effect.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of spark plug, structure is ingenious, long service life.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of spark plug, comprise central electrode and lateral electrode, described central electrode consists of the disk of straight-bar and bottom, and straight-bar is fixedly connected on this disk centre; Described lateral electrode is circular, and described disk is located at the circle centre position of described lateral electrode; The alloy that described disk consists of the chromium of 60～98% iridium and 2～40% is made.
Further, the outward flange of described disk is semi-circular structure, and this semicircle summit is 0.7～1.1mm apart from described lateral electrode inwall distance.
Further, the height of described lateral electrode is higher than described central electrode 0.3～0.6mm.
Compared with prior art, the present invention has the following advantages: central electrode top is made as discoid, correspondingly lateral electrode is made as circular, increased machining area, improved discharge effect; Simultaneously circular lateral electrode, has reduced the use that has carbon distribution phenomenon and affect spark plug, relative prolongation the useful life of spark plug.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of spark plug as shown in Figure 1, comprises central electrode 1 and lateral electrode 2, and described central electrode 1 consists of the disk 11 of straight-bar and bottom, and straight-bar is fixed on this disk 11 centre; Described lateral electrode 2 is circular, and described disk 11 is located at the circle centre position of described lateral electrode 2.Discharge process between central electrode 1 and lateral electrode 2, is to carry out through the edge of disk 11 and the circle ring inner wall of periphery, compares traditional spark plug configuration, and the discharge effect of this spark plug is good, can be because not occurring that carbon distribution causes the phenomenon that cannot discharge to occur.
The outer peripheral outward flange of described disk 11 is semi-circular structure, and this semicircle summit is 0.7～1.1mm apart from described lateral electrode 2 inwall distances.The surrounding of whole disk 11 all can be used as discharge position, and discharge effect is good.The height of described lateral electrode 2 is higher than the height 0.3～0.6mm of described central electrode 1, and electric discharge phenomena are carried out in the annulus of lateral electrode 2.
The alloy that described disk 11 consists of the chromium of 60～98% iridium and 2～40% is made, and has good resistance to wear, long service life, and corrosion resistance and erosion performance are good.
Claims (3)
