One end of the insulation shell is provided with a ring groove and the other end is provided with a spark plug sleeve; the insulation shell is made by high-voltage-resistant rubber through injection molding; and the conductive spring is formed by winding manganese steel wires. The high-voltage rod can be used for a booster gasoline engine, connects a branch cylinder high energy ignition coil with a spark plug and safely and effectively and reliably transfers high energy ignition coil secondary high voltage of the booster gasoline engine to a spark plug; the high-voltage rod has low energy loss, can meet requirements to parts performance by the booster gasoline engine, and effectively guarantees ignition energy of the booster gasoline engine.
Description
Technical field
The utility model belongs to the petrol engine parts, relates to a kind of high pressure stem.Be applicable in the gasoline supercharging engine and use.
Background technology
Constantly surging along with international oil price, " high power output, low fuel consume " become the Development of Auto Engine Technology direction and goal.Gasoline engine uses the charge inter cooling technology can not only satisfy small size, and high-power requirement can also provide good fuel economy, alleviates the world energy sources pressure that brings in short supply, might become the developing main flow of engine.Recent years, the gasoline engine supercharging technology obtained very fast development, and particularly along with the increasingly stringent of Abgasgesetz, increasingly high to the engine power performance requirement, supercharging technology is reducing discharging, and aspects such as bring to power play an important role.
Summary of the invention
The purpose of the utility model is intended to overcome above-mentioned deficiency of the prior art, and a kind of simple in structure, high pressure stem that result of use is good is provided.Thereby the requirement of a kind of adaptation supercharging gasoline engine operational environment is provided, high temperature resistant, high pressure resistant, connect the high-performance ignition coil and the spark plug that divide the cylinder igniting, transmit the secondary high voltage of ignition coil, effectively guarantee the high pressure stem of each cylinder reliable ignition of supercharging gasoline engine.
The content of the utility model is: a kind of high pressure stem is characterized in that: by hollow insulation crust (1) with place the power spring (2) in the insulation crust (1) to form; End in the said insulation crust (1) has annular groove (1-1), another section to be spark plug sleeve (1-2).
In the content of the utility model: said insulation crust (1) is the insulation crust of high voltage bearing silicon rubber injection mo(u)lding; This insulation crust (1) has high temperature+200 ℃ and does not have aging distortion, low temperature-40 ℃ not embrittlement, and power-frequency voltage 35KV such as does not puncture at superperformance.
In the content of the utility model: said power spring (2) is the power spring of manganese steel filament winding system; After this power spring (2) is assemblied on the engine, can closely be connected, effectively transmit high voltage, guarantee the spark plug reliable ignition with ignition coil secondary output end, spark plug head.
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) adopts the utility model; High pressure stem can be delivered to spark plug safely, effectively, reliably with the high-energy ignition coil secondary high electricity of gasoline supercharging engine; Energy loss is low, adapts to supercharging gasoline engine to the parts performance demands, guarantees higher ignition energy;

Description of drawings
Fig. 1 is the utility model example structure sketch map;
Fig. 2 is the utility model embodiment sectional structure sketch map;
Fig. 3 is the left TV structure sketch map of Fig. 1.
Among the figure: 1-insulation crust, 1-1-annular groove, 1-2-spark plug sleeve, 2-power spring.
Embodiment
The utility model is described further through embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of high pressure stem, by hollow insulation crust 1 with place the power spring 2 in the insulation crust 1 to form; End in the said insulation crust 1 has annular groove 1-1, another section to be spark plug sleeve 1-2.
During use, be used for supercharging gasoline engine, annular groove 1-1 one end that has of insulation crust 1 cooperates installation with the ignition coil head, is tightly connected, and effectively prevents electric leakage; One section of spark plug sleeve 1-2 of insulation crust 1 and spark plug ceramic package interference fit are tightly connected, and effectively prevent creepage; Thereby connect high-energy ignition coil and spark plug that gasoline engine divides the cylinder igniting, transmit the secondary high voltage of ignition coil.
In the foregoing description: said insulation crust is preferably and adopts high voltage bearing silicon rubber, can tolerate high-energy ignition coil working voltage, and not yielding in the hot environment in enging cabin, low temperature is difficult for embrittlement; Single injection-molded, compact conformation, production technology is simple, and the overall dimension consistency guarantees easily; Material is flexible, and is easy to assembly when insulation crust further leaves air vent hole, be used to discharge gas, with ignition coil and spark-plug body interference fit, is difficult for electric leakage, and fail safe is good;
In the foregoing description: said power spring is preferably the manganese steel filament winding system that adopts, good conductivity, and energy loss is low; Good springiness with ignition coil secondary output end and the tight crimping of spark plug head, connects reliable
The utility model is not limited to the foregoing description, and the utility model content is said all can implement and have said good result.
