Abstract
The invention discloses a spark plug. The spark plug comprises a central electrode and side electrodes, wherein the number of the side electrodes is at least two, the side electrodes are evenly distributed at the position below the central electrode, each side electrode is of an L shape, and the length of the horizontal section of each side electrode is smaller than the distance between the vertical section of the side electrode and the central electrode. According to the spark plug, due to the facts that the number of traditional side electrodes is more than one, and the side electrodes are evenly distributed around the central electrode, the discharging phenomenon is obvious, the contact surface is expanded, the service life of the electrodes is relatively prolonged, and discharging efficiency is improved.
Description
Technical field
The present invention relates to auto parts machinery technical field, especially a kind of spark plug.
Background technology
Spark plug is the important accessory in automobile engine, existing conventional spark plug basic structure is all sheathed metal shell outside insulator, and central electrode is set in insulator, and metal shell connects lateral electrode, two electrodes are close at spark plug tip place, to form sparking electrode pair.Conventional lateral electrode is L-type structure, and horizontal segment centre is over against central electrode, this simple in structure easy to use, but useful life is short, and effect is bad.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of spark plug, structure is ingenious, long service life.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of spark plug, comprise central electrode and lateral electrode, described lateral electrode is at least provided with two, is evenly distributed on central electrode below; Described lateral electrode is L-type, and the length of its horizontal segment is less than the distance between vertical section and central electrode.
Further, described lateral electrode is provided with four.
Further, described lateral electrode termination in the vertical direction is positioned in the periphery of central electrode.
Compared with prior art, the present invention has the following advantages: traditional lateral electrode is arranged a plurality of, be evenly distributed on around central electrode, make electric discharge phenomena obvious, contact-making surface increases, and has relatively extended the useful life of electrode, has improved discharging efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the upward view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of spark plug as illustrated in fig. 1 and 2, comprises central electrode 1 and lateral electrode 2, and described lateral electrode 2 is at least provided with two, is evenly distributed on central electrode 1 below; Described lateral electrode 2 is L-type, and the length of its horizontal segment is less than the distance between vertical section and central electrode 1.Between central electrode 1 and lateral electrode 2, arcing distance increases, and discharge path increases, and has improved discharge effect, relatively increases machining area, has extended the useful life of electrode.
Described lateral electrode 2 is provided with four, is located between two tiltedly below of central electrode 1 over against ground; Described lateral electrode 2 termination in the vertical directions are positioned in the periphery of central electrode 2.
Claims (3)
1. a spark plug, comprises central electrode and lateral electrode, it is characterized in that: described lateral electrode is at least provided with two, is evenly distributed on central electrode below; Described lateral electrode is L-type, and the length of its horizontal segment is less than the distance between vertical section and central electrode.
2. spark plug as claimed in claim 1, is characterized in that: described lateral electrode is provided with four.
