- the housing of the ignition device are
- the Anschraubbuchsen In order to prevent corrosion of the Anschraubbuchsen, the Anschraubbuchsen usually made of a metallic material are coated with a corrosion protection layer. However, the applied on the Anschraubbuchse corrosion protection layer has the
- the ignition device according to the invention with the features of claim 1 has the advantage that in a housing for fixing the housing a Anschraubbuchse can be provided, which has no corrosion protection coating. This ensures that in a production of the housing with inserted Anschraubbuchsen no chipping and accordingly no baubles can occur, which can limit the functioning of the ignition device. As a result, the manufacturing process and a subsequent quality inspection can be significantly simplified, so that a large cost savings potential exists.
- the corrosion coating-free Anschraubbuchse is disposed in a through hole in the housing, wherein the housing has on an outer side adjacent to an opening of the through hole has a sealing contour.
- the sealing contour is designed such that the sealing contour completely circumferentially around the
- Opening of the through hole is provided.
- the sealing contour then comes with a bolt or a washer or a contact surface of the engine part or the like. so in contact, so that the
- Anschraubbuchse is sealed to the outside. This makes it possible to dispense with the corrosion coating of the Anschraubbuchse, since the sealing contour makes contact between the Anschraubbuchse and the
- the sealing contour comprises a circumferential, protruding ring. This allows easy production.
- the sealing contour is formed integrally with the housing and made of the same material as the housing.
- a seal on the sealing contour is preferably carried out by a plastic deformation of the sealing contour by screwing a
- the deformation of the sealing contour provides a particularly secure seal ready.
- a first sealing contour at a first opening of the through hole and a second sealing contour at a second opening of the through hole are arranged. This makes it possible that the directed to a motor component side of the housing is sealed in the region of Anschraubbuchse, so that a particularly secure seal is made possible on both end sides of the Anschraubbuchse.
- the first and second sealing contour have the same dimensions and / or the same diameter.
- the sealing contour is arranged such that a first annular clearance is provided on a radial inner side of the sealing contour and a second annular clearance is provided on a radial outer side of the sealing contour. This ensures that immediately adjacent to the sealing contour on both sides a sufficient space is available, so that a
- an end surface of the sealing contour is arranged such that the end surface of the sealing contour by a predetermined height above a to
- the ignition device comprises an annular region, which is arranged radially within the first free space.
- This ring area serves as a lateral abutment for the Anschraubbuchse and limits the lying on the radial inner side of the sealing contour clearance.

- Ignition device 1 according to a preferred embodiment of the invention described in detail.
- the ignition device 1 comprises a housing 2 for receiving an ignition coil and further components, which is shown in perspective in FIG.
- a housing 2 for receiving an ignition coil and further components, which is shown in perspective in FIG.
- one or more through-holes 8 are provided with inserted Anschraubbuchsen 3 in the housing through which a bolt 7 is inserted therethrough.
- Such a fixation of the housing 2 is shown in Figure 4.
- Anschraubbuchse 3 is a cylindrical sleeve which receives a shaft 71 of the bolt 7.
- the Anschraubbuchsen 3 have always been coated with a corrosion protection layer, which problems may arise from spalling and tinsel. Therefore, the Anschraubbuchse 3 is executed without corrosion protection coating according to the invention.
- a sealing contour 4 is provided annularly around the through-hole 8 in the housing 2, in which the screw-on bushing 3 is arranged.
- the sealing contour 4 is an annular projecting area, which is injected together with the rest of the housing 2. Radially within the sealing contour 4, a first free space 5 is formed and radially outside the sealing contour 4, a second free space 6 is formed.
- the sealing contour 4 has a height 11 with which an end surface 40 of the sealing contour is formed over a base surface 20 of the housing in the immediate vicinity of the through-bore 8. Furthermore, as can also be seen from FIG. 3, at a radial one
- the annular sealing contour 4 is provided around the outer circumference of the opening of the through-hole 8.
- the sealing contour 4 is surrounded in the radial direction on both sides by free spaces 5, 6, which allow a plastic deformation of the sealing contour 4 when the housing 2 is fastened to an engine component 10.
- a radial width of the first free space 5 is equal to a radial width of the second free space 6.
- FIG. 5 shows a head 70 of the bolt 7 in FIG.
- FIG. 6 shows a shaft region 71 of the screw bolt, which is screwed into the engine component 10, wherein a small gap is present between the shaft region 71 of the screw bolt 7 and the inner wall surface of the screw bushing 3. As can be seen from Figure 6, is also at the other opening of the
- FIG. 6 once again shows the mounted state of the housing 2 on the engine component 10, wherein a deformation of the sealing contour 14 has already taken place.
- Corrosion protection coating are arranged, as done by the sealing contours 4, 14 sealing the Anschraubbuchse 3 against the outside environment. Thus, there is no risk of corrosion of not
- a ring region 19 corresponding to the annular region 9 at the first opening is provided at the second opening of the through-hole 8.
- an improved sealing geometry along a circumference of Anschraubbuchsen 3 for fixing the ignition device can be achieved, the sealing geometry must be made in a simple and cost-effective manner simultaneously with the production of the housing 2.
