Description
Technical field
The present invention relates to the technical field of car electrics, especially a kind of metal shell combustion gas high-voltage conducting wires.
Background technique
Existing gas engine high-pressure ignition wire is generally made of pure silica gel material, and silica gel material proof voltage can be good, is difficult
It is resistant to the high temperature of gas engine.And other materials cannot be considered in terms of two performances of proof voltage and high temperature resistant mostly.Polytetrafluoroethylene (PTFE)
It is a small number of materials for taking into account two kinds of performances, using the high-pressure ignition wire of polytetrafluoroethylene (PTFE) material, because the prices of raw materials are higher, system
Make complex process, causes higher cost.Aluminum alloy material has good temperature tolerance, but does not have insulating properties.Extrusion type poly- four
Fluoride tubes have good temperature tolerance, insulating properties, and cost has greater advantage compared to the polytetrafluoroethylene (PTFE) material of common Vehicle Processing,
But material molding thickness is lower, does not have structural strength.Both the above material is used alone and is all unable to satisfy gas engine high pressure
Ignition lead requirement.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of gold to solve the problems, such as above-mentioned background technique
Belonging to shell combustion gas high-voltage conducting wires, structure is simple, temperature tolerance and insulating properties are had both, and aluminum alloy casing has good thermal diffusivity,
Spark plug can be transmitted to the heat of high-pressure ignition wire inside configuration, quickly distributed, sealed silicone part is avoided to be chronically at
The condition of high temperature effectively promotes the service life of high-pressure ignition wire.
The technical solution adopted by the present invention to solve the technical problems is: a kind of metal shell combustion gas high-voltage conducting wires have
Aluminum alloy casing plugs extrusion polyfluortetraethylene pipe, the extrusion polyfluortetraethylene pipe on the aluminum alloy casing inner wall
Power spring is inside plugged, the upper end of the aluminum alloy casing is fixedly connected with insulation tube, and the insulation tube upper end is fixedly connected
Cylinder mouth sheath, the aluminum alloy casing lower end, which is located to squeeze out, is fixedly installed sealing sheath at polyfluortetraethylene pipe port position.
It further limits, in above-mentioned technical proposal, the lower end of the sealing sheath also plugs spark plug；Convenient for spark
The igniting of plug.
It further limits, in above-mentioned technical proposal, after the spark plug end extends to extrusion polyfluortetraethylene pipe
It is contacted with power spring end；Its temperature tolerance and insulating properties can be improved by squeezing out polyfluortetraethylene pipe.
Further limit, in above-mentioned technical proposal, the sealing sheath side wall structure wave-shaped.
The beneficial effects of the present invention are: a kind of metal shell combustion gas high-voltage conducting wires proposed by the present invention, structure is simple, has both
Temperature tolerance and insulating properties, and aluminum alloy casing has good thermal diffusivity, can be transmitted to spark plug in high-tension ignition cable architecture
The heat in portion, quickly distributes, and avoids sealed silicone part hot soak condition, effectively promotes the use of high-pressure ignition wire
Service life.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
The some embodiments recorded in application, for those of ordinary skill in the art, without creative efforts,
It is also possible to obtain other drawings based on these drawings.
Fig. 1 is structural schematic diagram of the invention.
Label in attached drawing are as follows: 1, aluminum alloy casing, 2, polyfluortetraethylene pipe, 3, power spring, 4, insulation tube, 5, cylinder mouth
Sheath, 6, sealing sheath, 7, spark plug.
Specific embodiment
In order to which the technical problems, technical solutions and beneficial effects solved by the present invention is more clearly understood, below in conjunction with
Accompanying drawings and embodiments, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
See that Fig. 1 is a kind of metal shell combustion gas high-voltage conducting wires, there is aluminum alloy casing 1, plugged on 1 inner wall of aluminum alloy casing
Polyfluortetraethylene pipe 2 is squeezed out, squeezes out in polyfluortetraethylene pipe 2 and plugs power spring 3, the upper end of aluminum alloy casing 1 is fixedly connected
Insulation tube 4,4 upper end of insulation tube are fixedly connected with cylinder mouth sheath 5, and 1 lower end of aluminum alloy casing, which is located at, squeezes out 2 port of polyfluortetraethylene pipe
Sealing sheath 6 is fixedly installed at position.
Wherein, the lower end of sealing sheath 6 also plugs spark plug 7.7 end of spark plug, which extends to, squeezes out polyfluortetraethylene pipe 2
It is contacted afterwards with 3 end of power spring.6 side wall of sealing sheath structure wave-shaped.
The product of traditional product and the application progress Experimental comparison are learnt: 5000/class of traditional product yield, cost exist
40 yuan/part, at 220 DEG C, insulation performance 40kV, no anti-interference function, every product uses the working temperature of long-time service
150gPTFE material, the material are limited by environmental protection, and production capacity is very limited and price fluctuation is also larger, and production link is more, part
Using machining, human cost is high, and production capacity is lower, and transportation cost is higher；And the product of the application may be implemented 30000
In 35/part working temperature is used for a long time at 280 DEG C, insulation performance 50kV has anti-interference function in part/class, cost control；
Every product uses 8g PTFE material, alleviates the various problems that traditional product largely uses PTFE material；And part is using crowded
Molding is, it can be achieved that unmanned production, production capacity is higher, and transportation cost is very low out.
The metal shell combustion gas high-voltage conducting wires of the application are opposite to have the advantages that one with conventional gas high-voltage conducting wires, resistance to
Warm nature and insulating properties are high；Two, its heat dissipation performance can be improved using aluminum alloy casing 1, height temperate zone is avoided to influence the damage of component；
Three, the service life of combustion gas high-voltage ignition conductive wire can be greatly improved.
It is above-described, it is merely preferred embodiments of the present invention, but protection scope of the present invention is not limited to
This, anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention
And its inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
