shell 5 with radiating fin, S-shaped retaining washer 6, containing electricity The glass-sealing agent 7 of resistance, is embedded in steel core 8, pole bar 9 of discharging, and by electrode tie rod 10, discharge cartridge 11, by electrode tip 12, by electrode Head shell 13, by electrode tip shell back-up ring 14.It is described with indexing 1a, zigzag umbrella rib 1c, fixed hole 1b and internal thread A groove, or multiple-grooved are at least opened on the electric conductor of outer indexing high-voltage coupler 1;The number of preferably multiple-grooved is by angle value;Example Such as, the number of degrees of certain spark plug are 6, then number of slotting is 6;The number of degrees of certain spark plug are 7, then number of slotting is 7.Described coupling The electric conductor of 1 fluting screws in threaded one end 4 and tapping fixed hole 1b makes spark plug.Spark plug is screwed in engine Screwed hole in, S-shaped retaining washer 6 is closely fastened.The spark cap of rubber or plastic insulation shell is inserted with, coupling 1 is made Electrically conductive socket that electric conductor is connected with high pressure external connection and in cap is connected.When to ignition advance angle, electric current is passed sequentially through The interior induction reactance of coupling 1, threaded one end 4 and threaded other end 4b and inductance coil 15, the glass capsulation containing resistance Agent 7, is embedded in steel core 8, pole bar 9 of discharging, and by electrode tie rod 10, discharge cartridge 11, by electrode tip 12, by electrode tip shell 13, and Discharge in electric discharge cartridge 11 and by between electrode tip 12.Described part 4, part 15, part 7, part 8, the insulated body 3 of part 9 particularly ceramics Body is surrounded, coupling capacitive reactance of just mutually meeting, and described resistance and inductance has the effect of connection in series-parallel RCL equivalent circuits, and allotment is suitable When just there is the effect of anti-radio interference.Shell 5 with radiating fin is because there is dissipating for the radiating fin more much bigger than original cylinder Hot area, it is self-evident that its thermal diffusivity has been improved.It is described with indexing 1a, zigzag umbrella rib 1c, fixed hole 1b and The zigzag umbrella rib 1c of the outer indexing high-voltage coupler 1 of internal thread, zigzag in the outer part is relatively delayed with the angle of axis, with sharp fire The socket of flower cap is easier to insertion;And zigzag in the inner part is more larger with the angle of axis, with the socket of sharp spark cap not Easily abjection.The groove depth of described fluting is the only about half of of coupling overall length;Fluting is different with its effect of not slotting, and is led It is easy to that micro- expansion forms multijaw after electric body fluting and the socket of favourable spark cap is difficult abjection.Because described is provided with band radiating fin The feature of shell 5 be provided with radiating fin 5a, radiating fin 5b, radiating fin 5c, particularly described radiating fin is hexagonal, or Person is circular, so to utilize original steel material as far as possible, the material that cut away in vain originally is retained a part and is made scattered Hot wing.Described radiating fin at least one or it is multiple.Radiating fin can be processed with hex wrench nut thereon with knife.Also just In install when box spanner can be inserted in it is deeper and more, be difficult skid.Because used as improving, the present invention is especially improved common single ordinary telegram Extremely cranked electrode 16;It is characterized in that:Described
