Description

A kind of metal shell combustion gas high-voltage conducting wires
Technical field
The utility model 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
Technical problem to be solved by the utility model is: providing one to solve the problems, such as above-mentioned background technique Kind metal shell combustion gas high-voltage conducting wires, structure is simple, has both temperature tolerance and insulating properties, and aluminum alloy casing has good heat dissipation Property, spark plug can be transmitted to the heat of high-pressure ignition wire inside configuration, quickly distributed, sealed silicone part is avoided to locate for a long time In the condition of high temperature, the service life of high-pressure ignition wire is effectively promoted.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of metal shell combustion gas high-voltage conducting wires, With aluminum alloy casing, extrusion polyfluortetraethylene pipe, the extrusion polytetrafluoroethyl-ne are plugged on the aluminum alloy casing inner wall Power spring is plugged in alkene pipe, the upper end of the aluminum alloy casing is fixedly connected with insulation tube, and the insulation tube upper end is fixed Cylinder mouth sheath is connected, the aluminum alloy casing lower end, which is located at, squeezes out fixed setting sealing shield at polyfluortetraethylene pipe port position Set.
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 utility model are: the utility model proposes a kind of metal shell combustion gas high-voltage conducting wires, structure Simply, temperature tolerance and insulating properties are had both, and aluminum alloy casing has good thermal diffusivity, spark plug can be transmitted to high-tension ignition Heat inside cable architecture, quickly distributes, and avoids sealed silicone part hot soak condition, effectively promotion high-tension ignition The service life of line.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments as described in this application, for those of ordinary skill in the art, before not making the creative labor It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
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
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific implementation described herein Example is only used to explain the utility model, is not used to limit the utility model.
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 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, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is simultaneously It is not limited to this, anyone skilled in the art within the technical scope disclosed by the utility model, according to this reality It is subject to equivalent substitution or change with novel technical solution and its utility model design, should all covers the protection in the utility model Within the scope of.
