Abstract
The utility model relates to a spark plug. The spark plug comprises a grounding nut, an insulator, a central electrode and a shell, wherein the shell is connected with a side electrode; the side electrode comprises a rod-shaped electrode body arranged above the shell; one end of the electrode body is connected to the upper end edge surface of the shell by a connection rod; the other end of the electrode body is separated to form a first side electrode and a second side electrode; the front ends of the first side electrode and the second side electrode are oppositely bent respectively; a notch is formed between the first side electrode and the second side electrode; and the position of the notch is corresponding to the central electrode. According to the spark plug disclosed by the utility model, the side electrode is formed to be in the form of the notch, thus increasing ignition efficiency, improving heat-conducting performance, and being capable of avoiding flame inhibition.
Description
Technical field
The utility model relates to a kind of spark plug.
Background technology
Conventional ignition plug in using both at home and abroad at present, great majority are single central electrode and single-sided electrode structure.The discharge end of this spark-plug side electrode turn of bilge, cover centering electrode top, thereby covered electric spark, be unfavorable for that electric spark removes in the efficient solution of combustion mixture maximum, the electrode structure of this protected type in addition, sparking-plug electrode part electric spark is produced to the moment expansion of right flame of wink, form and cover and the flame arrest effect, weaken electric spark electric heating energy.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of spark plug that can avoid flame arrest.
The technical scheme in the invention for solving the technical problem is:
A kind of spark plug, comprise grounding nut, insulator, central electrode and housing, housing is connected with lateral electrode, described lateral electrode comprises the rod-shaped electrode body that is arranged on the housing top, one end of electrode body is connected on housing upper end edge face by connecting rod, and the other end separately forms the first side pole and the second side pole, and the front end of the first side pole and the second side pole is bending in opposite directions respectively, form a notch between the first side pole and the second side pole, the corresponding central electrode of described notch position.
As preferably, the first side pole and the second side pole are symmetrical arranged.
As preferably, be provided with threaded portion on housing, axially be provided with more than one cleaning groove on threaded portion, the cleaning groove runs through and is arranged on described threaded portion outer surface.
As preferably, clear up groove and be provided with 3.
Lateral electrode is arranged to the first side pole and the second side pole, between the first side pole and the second side pole, forms notch, the corresponding central electrode of notch, be that lateral electrode is open annular, increased like this lateral electrode area, ignition effectiveness is higher, increase heat conductivility, and can also avoid flame arrest.Axially run through the cleaning groove is set at the threaded portion of housing outer surface, when screwing in corresponding internal thread, can effectively remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
The beneficial effects of the utility model are: the utility model is set to the notch form by lateral electrode, has not only increased ignition effectiveness and has increased heat conductivility, and can also avoid flame arrest.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of spark plug, comprise grounding nut 10, insulator 9, central electrode 5 and housing 8, housing 8 is connected with lateral electrode, lateral electrode comprises the rod-shaped electrode body that is arranged on the housing top, one end of electrode body is connected on housing 8 upper end edge faces by connecting rod 1, the other end separately forms the first side pole 2 and the second side pole 4, the front end of the first side pole 2 and the second side pole 4 is bending in opposite directions respectively, form a notch 3 between the first side pole 2 and the second side pole 4, the corresponding central electrode 5 in described notch 3 positions.The first side pole and the second side pole are symmetrical arranged.Be provided with threaded portion 7 on housing, axially be provided with the cleaning groove 6 of 3 on threaded portion, the cleaning groove runs through and is arranged on described threaded portion outer surface.
Lateral electrode is arranged between the first side pole 2 and the second side pole 4, the first side poles 2 and the second side pole 4 form notch 3, the corresponding central electrode of notch, be that lateral electrode is open annular, increased like this lateral electrode area, ignition effectiveness is higher, increase heat conductivility, and can also avoid flame arrest.Axially run through cleaning groove 6 is set at the threaded portion of housing 87 outer surfaces, when screwing in corresponding internal thread, can effectively remove the dirt that threaded connection place retains, the problem of arc control plug ablation.
The utility model is set to the notch form by lateral electrode, has not only increased ignition effectiveness and has increased heat conductivility, and can also avoid flame arrest.
Claims (4)
