There are lateral electrode, the connecting sleeve upper surface to offer cupuliform slot, the connecting sleeve inner surface wall is provided with holding ring, the folder
Held in ring inner surface wall is provided with elastic ring and the matched through-hole used, and runs through inside through-hole and be connected with wiring screw rod, described
Connecting terminal is provided at the top of wiring screw rod, the wiring screw rod bottom passes through in sealing ring and the lower insulation tube of shell inner surface wall
Central electrode connection.
As further describing for above-mentioned technical proposal：
The outer surface of the upper insulation tube and lower insulation tube offers the thread groove for connection.
As further describing for above-mentioned technical proposal：
The cross section of the lateral electrode is arcuate structure.
As further describing for above-mentioned technical proposal：
The upper end diameter of the cupuliform slot is more than lower end diameter 3mm.
As further describing for above-mentioned technical proposal：
The junction of the wiring screw rod and central electrode is provided with the sealant for seal protection.
As further describing for above-mentioned technical proposal：
The diameter of the through-hole is equal with the diameter of wiring screw rod.
In the utility model, first, the terminals of the spark plug use the structure design of cupuliform, can be complete by connecting terminal
Hermetically sealed insertion junction is installed, and avoids the junction of connecting terminal from the phenomenon that gap occur, while also allowing for spark
The installing and dismounting of plug operates, and greatly improves the mounting stability of spark plug, secondly, can be right by the holding ring of setting
The effect gripped is played in the operating position of wiring screw rod, prevents what wiring screw rod from shaking by vibrations at work to show
As, to protect central electrode ignition location consistency, improve the safety in utilization of spark plug, on the other hand the fire
Flower plug overall construction design advantages of simple, takes easy to operate, and connection sealing is stablized, and has stronger practicability.
