Description
Technical field
The present invention relates to the igniter in a kind of combustion apparatus, especially a kind of gasoline motor spark plug, the technical field that belongs to anti-High-frequency Interference and prevent the spark plug that grafting gets loose with interior induction reactance and high pressure coupling.
Background technology
The igniter that is used for combustion apparatus, especially gasoline motor spark plug are widely used in the high voltage pulse electric current is introduced into the combustion chamber, and make the gaseous mixture sparking of inspiration cylinder and light, and then diffusion combustion and break out work done.The outside coupling of existing spark plug and having between the spark cap of rubber jar has the loose diffusing phenomenon of pine sometimes.Resistance is made though be provided with glass-sealing agent in the inside of existing spark plug, and impedance is only arranged; If add induction reactance and capacitive reactance, form suitable R CL loop, then have the effect of better inhibition radio interference.Multiple tracks umbrella rib on the insulator also can be improved to saw-tooth shaped cross section by semi-circular cross-section, better blocks rubber jar so that the creepage passage of more insulation reaches.The heat radiation of the metal shell of existing spark plug also can further improve.The electrode of existing spark plug is well imagined, the knot of being prone to charcoal is arranged, and is prone to ablate single-point arcing, the shortcoming of low temperature difficult point.Described problem is a hard nut to crack.In order to remedy a kind of igniter that is used for combustion apparatus; Especially the shortcoming of operating state due to the existing mechanism of gasoline motor spark plug; The present invention provides the method for a kind of gasoline motor spark plug with interior induction reactance and outer calibration high pressure coupling; And add shell heat radiation wing, so that improve the present situation of spark plug, make it more durable in use.
Summary of the invention
The technical scheme that the present invention taked is:
A kind of igniter that is used for combustion apparatus, especially gasoline motor spark plug are used for anti-High-frequency Interference and the anti-spark plug of pegging graft and getting loose, by having calibration (1a) with interior induction reactance and outer calibration high pressure coupling; Zigzag umbrella rib (1c), the outer calibration high pressure coupling (1) of fixing hole (1b) and internal thread, pad (2); The insulator (3) of the multiple tracks umbrella rib of toothed tee section, the interior induction reactance of a threaded end (4) and the threaded other end (4b) and inductance coil (15), the shell (5) of band heat radiation wing; S shape retaining washer (6) contains the glass-sealing agent (7) of resistance, embeds steel core (8); Discharge electrode bar (9) receives electrode tie rod (10), discharge cartridge (11); Receive electrode tip (12), receive electrode tip shell (13), formed by electrode tip shell back-up ring (14); The described calibration (1a) that has, zigzag umbrella rib (1c), the characteristic of the outer calibration high pressure coupling (1) of fixing hole (1b) and internal thread is: the described calibration (1a) that has is by equal calibration fluting on the electric conductor of described coupling (1); At least open a groove, or multiple-grooved; Preferably the number of multiple-grooved is by the degree value; For example, the number of degrees of certain spark plug are 6, and the number of then slotting is 6; The number of degrees of certain spark plug are 7, and the number of then slotting is 7.Though the number of degrees of the calorific value of general spark plug are divided into 5-13 by the difference of engine by the internal structure of spark plug, the bigger just nearlyer cold mould of numerical value, the engine that is fit to high rotating speed high compression ratio uses; The more little just near-thermal type more of numerical value, the engine that is fit to low compression ratio uses; But difficult appearance from spark plug is judged, or is prone to obscure.The beneficial effect of on the electric conductor of the coupling of spark plug, slotting has two, one, makes the selecting for use of the number of degrees of the calorific value of spark plug be difficult for obscuring, and the 2nd, make the coupling of the latch capitiform of original Dan Yuan make the latch effect better owing to fluting becomes claw type.The electric conductor of the fluting of described coupling (1) is to be inserted with in and the electrically conductive socket in cap that link to each other with the high pressure external connection of spark cap of rubber or plastic insulation shell.
The described calibration (1a) that has; Zigzag umbrella rib (1c), the further feature of the outer calibration high pressure coupling (1) of fixing hole (1b) and internal thread is: described zigzag umbrella rib (1c), like Fig. 5; Fig. 6 and Fig. 9; Shown in Figure 10, the zigzag in the outer part and the angle of axis are more slow, insert in order to the socket of spark cap is easy; And the angle of zigzag in the inner part and axis is bigger, is difficult for deviating from order to the socket of spark cap.Like Fig. 5, Fig. 6 and Fig. 7, Fig. 8, shown in Figure 9, described groove depth is the half the of coupling length overall; Fixing hole (1b) is located at i.e. in the inner part the end of the end of not slotting, so that knock fixing.The internal thread of described coupling (1d); Like Fig. 6, Fig. 1 and shown in Figure 2 links with a threaded end (4); And the insulator (3) of the multiple tracks umbrella rib of setting-up piece (2) and toothed tee section, and the interior induction reactance of a threaded end (4) and the threaded other end (4b) and inductance coil (15); A threaded end (4) links to each other with inductance coil (15); Inductance coil (15) links to each other with the threaded other end (4b); The glass-sealing agent (7) of the threaded other end (4b) through containing resistance, with embedding steel core (8), discharge electrode bar (9) links to each other.Described (4), part (15), part (7), part (8), part (9) insulated body (3) particularly ceramic body surrounds, just meeting coupling capacitive reactance mutually, said resistance and inductance have the effect of connection in series-parallel RCL equivalent electric circuit, and allotment suitably just has the effect of anti-radio interference.Embed steel core (8) and insert discharge electrode bar (9), in order to gaining in strength and heat conduction.Discharge electrode bar (9) or participate in discharge directly, or link to each other with discharge cartridge (11) that special special material is processed.Receive electrode tie rod (10) at least one or a plurality of; Or participate in discharge directly; Or link to each other with the electrode tip (12) that receives that special special material is processed, or link to each other with the electrode tip (12) that receives that special special material is processed, and install additional and receive electrode tip shell back-up ring (14) through receiving electrode tip shell (13).The characteristic of the insulator (3) of the multiple tracks umbrella rib of described toothed tee section is, the zigzag of described zigzag umbrella rib and the angle of axis are more slow, is prone to wrap in order to the rubber or the plastic insulation shell of spark cap; And the angle of zigzag in the inner part and axis is bigger, is difficult for deviating from order to the rubber or the plastic insulation shell of spark cap.The zigzag of described zigzag umbrella rib has than original semicircle umbrella rib more Duos the creepage passage of insulation and can better block rubber jar.The outside of an end of (being inner discharge side) in the inner part of the insulator (3) of the multiple tracks umbrella rib of described toothed tee section is provided with the shell (5) of being with the heat radiation wing, and S shape retaining washer (6).
