Abstract
The utility model relates to a spark plug with an improved side electrode structure. 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 first connection rod and a second connection rod which are bridged above the shell; the first connection rod and the second connection rod are connected by an electrode ring; and the position of the electrode ring is corresponding to the position of the central electrode. According to the spark plug disclosed by the utility model, the side electrode is formed to be annular, so that spark energy cannot be weakened; and an auxiliary electrode is arranged to enhance firepower.
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 that improves side electrode structure, comprise grounding nut, insulator, central electrode and housing, housing is connected with lateral electrode, described lateral electrode comprises head rod and the second connecting rod that is connected across the housing top, connect corresponding central electrode position, electrode retaining collar position between head rod and the second connecting rod by electrode retaining collar.
As preferably, head rod and the second connecting rod include respectively the vertical section that is connected housing and the transverse part of connecting electrode ring, the inboard of vertical section extended internally respectively the first auxiliary electrode and the second auxiliary electrode, the spacing between the first auxiliary electrode and the second auxiliary electrode is identical with the diameter of electrode retaining collar.
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.
Electrode retaining collar is set above central electrode, is about to lateral electrode and is arranged to ring-type, and be fixedly connected on housing by head rod and the second connecting rod, the lateral electrode of ring-type can not weaken the electric spark energy.Inboard in the vertical section of head rod and the second connecting rod also arranges the first auxiliary electrode and the second auxiliary electrode, and two auxiliary electrodes can have the function that strengthens firepower.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 arranged to ring-type by lateral electrode, can not weaken the electric spark energy, and auxiliary electrode is set, and strengthens firepower.
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 that improves side electrode structure, comprise grounding nut 8, insulator 7, central electrode 4 and housing 6, housing is connected with lateral electrode, lateral electrode comprises head rod 9 and the second connecting rod 3 that is connected across the housing top, connect corresponding central electrode 4 positions, electrode retaining collar 2 positions between head rod 9 and the second connecting rod 3 by electrode retaining collar 2.Head rod 9 and the second connecting rod 3 include respectively the vertical section that is connected housing and the transverse part of connecting electrode ring, extended internally the respectively diameter of spacing between the first auxiliary electrode 1 and the second auxiliary electrode 10, the first auxiliary electrodes 1 and the second auxiliary electrode 10 and electrode retaining collar 2 of the inboard of vertical section is identical.Be provided with threaded portion 5 on housing, axially be provided with more than one cleaning groove 11 on threaded portion 5, cleaning groove 11 runs through and is arranged on described threaded portion 5 outer surfaces.Cleaning groove 11 is provided with 3.
Electrode retaining collar 2 is set above central electrode 4, is about to lateral electrode and is arranged to ring-type, and be fixedly connected on housing by head rod 9 and the second connecting rod 3, the lateral electrode of ring-type can not weaken the electric spark energy.In the inboard of the vertical section of head rod and the second connecting rod, the first auxiliary electrode 1 also is set and 10, two auxiliary electrodes of the second auxiliary electrode can have the function that strengthens firepower.Axially run through cleaning groove 11 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 utility model is arranged to ring-type by lateral electrode, can not weaken the electric spark energy, and auxiliary electrode is set, and strengthens firepower.
