Abstract
The utility model discloses a kind of bipolar automobile spark plug, comprise housing, insulator, grounding nut and central electrode, described housing is connected with lateral electrode, the bulge loop coaxially arranged with housing is provided with between described lateral electrode and housing, the external diameter of the shell one end be connected with bulge loop is greater than the external diameter of described bulge loop, the number of described lateral electrode is two and is uprightly arranged on described bulge loop, and described housing is also provided with some heat-radiating ring-grooves.The bipolar automobile spark plug of the one that the utility model obtains; its technique effect is: arrange two upright lateral electrodes; flame arrest phenomenon can be avoided; improve the ignition effectiveness of spark plug, increase arcing passage, bulge loop is set between lateral electrode and housing; protection lateral electrode; reduce collision and pollute, ensure the useful life of lateral electrode, thus the useful life of extending plug.
Description
Technical field
The utility model relates to a kind of spark plug.
Background technology
Conventional ignition plug in using at present both at home and abroad, comprises housing, insulator, grounding nut and central electrode, described housing is connected with lateral electrode, and great majority are the such structures of a central electrode and a lateral electrode.The discharge end of this spark-plug side electrode bend, covers above central electrode, thus covers electric spark, sparking-plug electrode part electric spark is produced to the moment expansion of wink combustion flame, formed and cover and flame arrest effect, weaken electric spark electric heating energy, reduce arcing performance.And after Long-Time Service, the electrode meeting carbon distribution of spark plug, useful life is short, and carbon distribution too much can cause spark plug to scrap, and automobile cannot start.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind ofly to be avoided flame arrest phenomenon and can improve the bipolar automobile spark plug in spark plug useful life.
To achieve these goals, the bipolar automobile spark plug of one designed by the utility model, comprise housing, insulator, grounding nut and central electrode, described housing is connected with lateral electrode, the bulge loop coaxially arranged with housing is provided with between described lateral electrode and housing, the external diameter of the shell one end be connected with bulge loop is greater than the external diameter of described bulge loop, and the number of described lateral electrode is two and is uprightly arranged on described bulge loop, and described housing is also provided with some heat-radiating ring-grooves.
Adopt two lateral electrodes, and uprightly arrange, lateral electrode does not have bend cover in central electrode, flame arrest phenomenon can be avoided, improve ignition effectiveness, and owing to being two lateral electrodes, add arcing passage, extend the useful life of spark plug.The bulge loop that external diameter is less than housing end face is set between lateral electrode and housing, is conducive to spark plug when mounted, reduce collision and the pollution of lateral electrode, ensure the normal use of lateral electrode.Housing is provided with heat-radiating ring-groove, is conducive to heat radiation, the useful life of extending plug.
Further, described housing comprises the upper shell and lower house that are threaded, and described lateral electrode, bulge loop and described upper shell integral type are arranged.
Further, described housing is provided with threaded portion, described threaded portion is axially arranged with more than one cleaning groove, and described cleaning groove runs through and is arranged on described threaded portion outer surface.
The bipolar automobile spark plug of the one that the utility model obtains; its technique effect is: arrange two upright lateral electrodes; flame arrest phenomenon can be avoided; improve the ignition effectiveness of spark plug, increase arcing passage, bulge loop is set between lateral electrode and housing; protection lateral electrode; reduce collision and pollute, ensure the useful life of lateral electrode, thus the useful life of extending plug.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, the bipolar automobile spark plug of the one that the utility model provides, comprise housing 1, insulator 2, grounding nut 3 and central electrode 4, described housing 1 is provided with the coaxial bulge loop 5 arranged with described housing 1 away from insulator 2 one end, the external diameter of housing 1 one end be connected with bulge loop 5 is greater than the external diameter of described bulge loop 5, and described bulge loop 5 is provided with two lateral electrodes 6 uprightly arranged.Two lateral electrodes 6 can be symmetricly set on bulge loop 5 according to central electrode 4; also can asymmetrically be arranged on bulge loop 5; be the latter in the present embodiment; external diameter due to bulge loop 5 is less than the external diameter of the housing end face be connected with bulge loop; when installing spark plug, lateral electrode 6 can not come in contact with miscellaneous part or collide, and makes lateral electrode 6 when mounted can not be contaminated and damaged by colliding; the normal use of protection lateral electrode 6, thus ensure the normal use of spark plug.Two lateral electrodes 6 are compared to conventional ignition plug and provide an arcing passage more, extend the useful life of spark plug, improve the reliability of igniting, and due to these two lateral electrodes 6 be all upright setting, do not have bend can not cover in central electrode 4, thus avoid flame arrest phenomenon, improve ignition effectiveness.The space formed between two lateral electrodes 6, can maximized increase air circulation, spark energy is delivered in gaseous mixture rapidly and goes, and can improve ignition effectiveness and reduce carbon distribution, further ensure the use of lateral electrode.
In the present embodiment, described housing 1 is provided with some heat-radiating ring-grooves 7, increases the radiating rate of housing 1, the useful life of extending plug.
In the present embodiment, described housing 1 comprises the upper shell and lower house that are threaded, is conducive to the dismounting of upper shell and lower house, easy cleaning spark plug, the useful life of extending plug.Described lateral electrode 6, bulge loop 5 and described upper shell integral type are arranged, and ensure the useful life of spark plug.
In the present embodiment, described housing 1 is provided with threaded portion 8, described threaded portion 8 is axially arranged with more than one cleaning groove 9, described cleaning groove 9 runs through and is arranged on described threaded portion 8 outer surface, when screwing in corresponding internal thread, effectively can remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
