Abstract
A side electrode of a sparking plug comprises a metal shell connected with a sparking plug, a central electrode and a side electrode, wherein the side electrode is welded on the metal shell of the sparking plug. The utility model is characterized in that a step is arranged on the end opening of the metal shell of the sparking plug, is part of the side electrode of the sparking plug, and is in an arc annular shape; the width of the arc annular step is not more than one third of the diameter of the end opening of the whole metal shell; a notch is dispensed on the step, and the side electrode of the sparking plug is inlaid in the notch of the step into a whole body by welding. The width of the side electrode is 4 plus or minus 0.05mm, and is vertical to the central electrode, so that a reasonable gap is formed.
Description
Technical field:
The utility model belongs to a kind of modular construction of engine, is that a kind of spark plug configuration of engine improves specifically, is mainly used in the various engines.
Background technology:
Spark plug function is the high voltage pulse discharge of electricity that high-voltage line is passed over, and disruptive spark plug two interelectrode air produce electric spark with the mist in this gas cylinder, make engine running.Common spark-plug side electrode is generally 2.8mm (width) * 1.5mm (thickness) list structure, utilizes professional welding equipment to be welded on the housing port, and with lateral electrode curved to the central electrode upright position, form the gap with central electrode.Central electrode and lateral electrode are made by nickel or nickel alloy, the high temperature in the time of bearing outburst, and electric current is skipped between electrode during spark plug work, produces the heat-flash spark, and the gas of lighting compressed mixed in the cylinder carries out electrical ignition, produces the kinetic energy drive engine.
But existing spark plug porcelain lateral electrode is therefore less with the bonding area of spark-plug body owing to narrow, after the long-term igniting of spark plug, occurs burning phenomenon easily, causes durability to be affected.Therefore, necessary existing spark-plug side electrode is improved.
The utility model content:
The purpose of this utility model is: at the deficiency of existing spark plug porcelain lateral electrode, it is better to propose a kind of spark-plug side electrode welding performance, longer service life, and be not easy to occur the spark-plug side electrode of spark-plug side electrode burning phenomenon.
The technical solution of the utility model is: a kind of spark-plug side electrode, comprise and connect spark plug metal shell, central electrode and lateral electrode, lateral electrode is welded on the spark plug metal shell, its characteristics are on the described spark plug metal shell port step is arranged, step is the part of spark-plug side electrode, step is a curved annular, and the width of arc shape step is no more than 1/3 of whole metal shell port diameter; Have notch on step, spark-plug side electrode is embedded in the notch of step, and by being welded into one.The lateral electrode width is 4 ± 0.05mm, becomes the upright position with central electrode, and forms reasonable clearance.
Advantage of the present invention:
1, the present invention goes into the lateral electrode scarfweld in the spark plug iron-clad step groove, and more common spark-plug side electrode solder side is bigger, welds more firmly, has improved the welding quality of spark-plug side electrode.
2, spark-plug body step of the present invention is real is the part of common spark-plug side electrode, this structure has increased the heat-conducting area of lateral electrode, being more conducive to is derived the heat-flash that when igniting between electrode produces rapidly by housing, strengthened the ablation resistance of spark plug, prolong the useful life of spark plug, more be applicable to the spark plug that heat load is high.

Fig. 2 is the utility model spark-plug side electrode part-structure schematic diagram;
Fig. 3 is the utility model spark-plug side electrode part-structure diagrammatic bottom view.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
By accompanying drawing 2 as can be seen, the utility model is a kind of spark-plug side electrode, comprise and connect spark plug metal shell 1, central electrode 2 and lateral electrode 3, lateral electrode 3 is welded on the spark plug metal shell 1, its characteristics are on described spark plug metal shell 1 port step 4 is arranged, step 4 is the part of spark-plug side electrode, and step 4 is a curved annular, and the width of arc shape step is no more than 1/3 of whole metal shell port diameter; Have notch on step 4, spark-plug side electrode 3 is to be embedded in the notch of step 4, and by being welded into one.The lateral electrode width is 4 ± 0.05mm, becomes the upright position with central electrode, and forms reasonable clearance.
Claims (2)
