Problems solved by technology
[0005] The purpose of the present invention is to provide a kind of stud type side electrode ignition pin and its manufacturing method. The main technical problem to be solved is: the existing precious metal side electrode ignition pin is directly welded on the spark plug production line. In addition to the problem that the different metals between the side electrode body fingers of noble metal and nickel-based metal are difficult to weld firmly and the welding failure will cause the spark plug to be scrapped, there is also the problem that the noble metal ignition pin is not easy to manage, which is not conducive to streamlined operation

The large-headed nail type side electrode igniting needle comprises an igniting needle base body (10) and a side electrode igniting contact (20), wherein the igniting needle base body (10) is in the shape of a large-headed nail and comprises an integrally formed a nail head (11) and a nail column (12), the igniting needle base body (10) and a side electrode body (1) of a sparking plug are made of the same material and both made of nickel base material, the side electrode igniting contact (20) is made of precious metal material, the side electrode igniting contact (20) is welded to the other end, corresponding to the nail head (11), of the nail column (20) of the igniting needle base body (10), one end of the nail head (11) of the igniting needle base body (10) is welded to the side electrode body (1), and the igniting needle base body (10) is axially perpendicular to the side face, corresponding to a central electrode, of the side electrode body (1).
Description
technical field [0001] The invention relates to the technical field of spark plugs, in particular to an ignition pin with a stud structure on a side electrode of a spark plug and a method for manufacturing the side electrode ignition pin with a stud structure. Background technique [0002] The use of noble metals with very stable chemical properties as the electrode needle of the ignition end of the spark plug has become the composition trend of the new generation of spark plugs. The use of noble metals to resist ablation, electrical corrosion and chemical corrosion and have good thermal conductivity is formed on the side electrode body composed of nickel-based metals. Ignition needle with tip discharge. The discharge tip, which uses precious metals to form electrodes, utilizes the relatively stable nature of the chemical properties of rare metals, and can still provide punctual and strong sparks under high temperature and high pressure at extremely high speeds. The ignitio...
