Description
Technical field
The present invention relates to corona ignition device, it has the existing skill as known to from DE 10 2,013 104 643 B3
The feature of art.
Background technology
This type of corona ignition device lights fuel in internal combustion engine.In the motor vehicle, corona ignition device not only exposes
In by the thermal stress produced of running of electromotor, and shock and vibration during being exposed to because of stroke and occur sizable
Mechanical stress.
Summary of the invention
It is an object of the invention to illustrate how to manufacture the corona point of mechanically robust to have cost-benefit mode
Fire device.
This problem is addressed by the corona ignition device with a first aspect of the present invention feature.The present invention's is favourable
Further modification be the theme of other side.
In the housing according to the corona ignition device of the present invention, layout of spring is between coil and cover.This spring is court
To the compression spring of central electrode pressing coil, the manufacture therefore compensating shell length, loop length or central electrode length is public
Difference.Hence it is advantageous to, despite the presence of length and position of related features, but the compression spring being arranged between cover and coil can be by coil
Fix in the housing.Therefore this corona ignition device can preferably bear the mechanical stress occurred during driver behavior.
The present invention further favorably improves regulation, and compression spring is to have the metallic plate of spring lug.This metallic plate
There is the opening guiding the electrical connection section of coil to pass.This metallic plate with spring lug can have cost-benefit side
From sheet metal punching press out, wherein spring lug is from the plain bending of plate out for formula.Spring lug can be resisted against on cover or can
Towards coil.
Attendant advantages in the compression spring of the metallic plate form with spring lug is, metallic plate can axially complete
The shielding of coil, such as, it can be the radial direction sheet metal casing of coil.To that end, it may be advantageous to metal plate as by by
Copper, aluminum or silver are made and are had high conductivity, or are carrying such as copper, aluminum, golden or silver-colored high connductivity towards the side of coil
Property coating.This coating preferably at least 0.1mm is thick.Can be such as multiple by electroplating on sheet metal, such as sheet metal or rolling
Close and be coated with application layer.
Accompanying drawing explanation
Referring to the drawings, further details and advantages of the present invention are described in the exemplary embodiment.There is shown:
Fig. 1 is the partial sectional view of the exemplary embodiment of the corona ignition device according to the present invention；
Fig. 2 is the detailed view of Fig. 1；And
Fig. 3 illustrates the exemplary enforcement of the compression spring between the cover and the coil that are arranged in shown corona ignition device

Detailed description of the invention
Corona ignition device shown in Fig. 1 has housing 1, and housing 1 is being positioned at the front end of combustion chamber side by insulator 2
Closing, be disposed with central electrode 3 in insulator 2, central electrode 3 extends to one or more igniting most advanced and sophisticated 4.Housing 1 is far
Rear end from combustor is closed by cover 5, cover 5 carrying plug-in connector 6, and corona ignition device can by plug-in connector 6 even
It is connected to voltage source.
Central electrode 3 is connected in series with coil 7.Coil 7 is wound on bobbin 8, bobbin 8 and central electrode 3 grafting
Together.This Plug Division between bobbin 8 and central electrode 3 can have shielding cap 9, and shielding cap 9 is around coil 7 and middle electrocardio
Electrical joint between pole 3.In addition to bobbin 8 with the mechanical connection of central electrode 3, this Plug Division also sets up bobbin
Electrical connection between 8 and central electrode 3.
In the manufacture of corona ignition device, procapsid part 1a of insulator 2 is kept to be soldered to the housing being adjacent
Part 1b, and there is the coil 7 of bobbin 8 by inserted into each other with central electrode 3 and be connected.At two housing parts 1a and
When 1b combines, procapsid part 1a such as forms retainer by having annular shoulder, and tubular shell part 1b is put
Put on this retainer.When being attached on central electrode 3, bobbin 8 can be mounted to adjoin equally, in wherein can such as passing through
Heart electrode 3 or insulator 2 form retainer.
The tolerance being added together during assembly is compensated by the compression spring 10 being arranged between coil 7 and cover 5.This type of
The exemplary embodiment of compression spring figure 3 illustrates.After compression spring 10 has been placed on bobbin 8, will cover 5 welding
To housing 1.
Compression spring can be such as to have the metallic plate of spring lug 10a, and this metallic plate has being electrically connected of guiding coil 7
Connect the opening 11 that portion 12 passes.The metallic plate with spring lug 10a can be fabricated to the bending ram parts of sheet metal.Institute
In the exemplary embodiment shown, spring lug 10a is resisted against on cover 5, and metallic plate self leans against the flange 8a of bobbin 8 simultaneously
On.The extension 8b of bobbin 8 highlights through the opening 11 of metallic plate.This extension 8b can carry the electrical connection section of coil 7, example
Contact pin 13 such as plug-in connector 6.
Compression spring 10 can such as be manufactured by steel or bronze, and the high conductivity can with such as copper, gold, silver or aluminum is coated with
Layer, in order to reduce eddy-current loss.Here, it is enough for being coated with application layer in the side towards coil 7 of compression spring 10.When passing through
When plating is coated with application layer, from the point of view of manufacturing, being coated with application layer in both sides can be favourable.This coating also can be such as by rolling
It is combined and is applied on sheet metal, then manufactured compression spring 10 by this sheet metal.
In order to reduce eddy-current loss, the inner side of housing 1 can have the conductive layer of such as copper, silver, aluminum or gold.As housing 1
The replacement of coating, coil can be by the shield of the sheet metal of such as copper or aluminum radially around within the case 1.
