Description

[0072] FIGS. 1a and 1b various side views of a plug-in coil element according to the invention;

[0073] FIGS. 2 to 4 various views of a housing according to the invention of the plug-in coil element;

[0074] FIG. 5 a pane according to the invention, and

[0075] FIG. 6 a plug-in coil element according to the invention in the mounted state.

[0076] In the following, the same reference numerals will be used for equal components or components of equal action.

[0077] In the FIGS. 1a and 1b, the plug-in coil element 10 is illustrated without the associated portions of the housing 20 (see FIGS. 2 to 4). The plug-in coil element 10 has a coil 13 having a winding body 30 and a coil support 14. The coil 13 thus comprises a winding body 30 of a current conductor made of wire, in particular made of copper wire. The coil support 14 may be formed of a ferromagnetic material, for example.

[0078] The winding body 30 has two ends, that is a first winding body end 31 and a second winding body end 32. Apart form the winding body 30, however, the coil 13 still comprises further wire portions, so that the first coil end 15 is formed to be spaced from the first winding body 31. The second coil end 16 is likewise formed to be spaced from the second winding body end 32.

[0079] It can be furthermore recognized that a first connecting element 11 is connected to the first coil end 15, and a second connecting element 12 is connected to the second coil end 16. The connecting element 11 (see FIG. 2) is formed as a plug-in sleeve. On the contrary, the second connecting element 12 is formed as a flat plug, preferably as a vehicle flat plug.

[0080] The two coil ends 15 and 16 are formed to be in parallel to the middle axis (not delineated) of the winding body 30. The coil ends 15 and 16 moreover point into the same direction. In the illustrated case, the coil ends 15 and 16 each point towards the left side. When FIGS. 3 to 4 are observed, it will be clear that the two coil ends 15 and 16 point into the plug-in direction S.

[0081] In order to be able to enable such a parallel arrangement of the coil ends 15 and 16 at a simultaneously equal orientation in a corresponding direction, a coil wire portion 19 is formed, which establishes a connection from the first winding body end 31 to the first coil end 15. For this purpose, the coil wire portion 19 is bent at least once.

[0082] It may moreover be recognized in FIGS. 1a and 1b that the first connecting element 11 is formed at the level of the second winding body end 32. This arrangement is likewise established by means of the coil wire portion 19.

[0083] The first connecting element 11 is laterally spaced from the winding body 30, but is at the level of the second winding body end 32 in the shown representations. Preferably, the first connecting element is on a perpendicular line to the middle axis of the winding body 30, wherein the perpendicular line intersects the second winding body end 32 or is only slightly spaced apart from this point of intersection.

[0084] In FIGS. 2 and 3, the plug-in direction S can be recognized. Thus, both the first connecting element 11 and the second connecting element 12 are mounted and slipped-in the same plug-in direction.

[0085] In FIGS. 2 and 3, the first connecting element 11 as well as the second connecting element 12 of the plug-in coil 10 can be recognized. The represented housing 20 covers the plug-in coil 10 almost in its entire extension. Only the second connecting element 12 is not covered in portions by the housing 20.

[0086] The housing 20 has a sheathing portion 21 protruding from a housing opening 39 to the outside. The sheathing portion 21 surrounds the connecting element 11 at least in portions. The sheathing portion 21 is formed such that it does not rest completely against the connecting element 11. Rather, a distance is formed between the first connecting element 11 and the sheathing portion 21 so that the formation of a plug-in sleeve is enabled.

[0087] The sheathing portion 21 has an access opening 45 pointing into the plug-in direction S. Thus, a plug-in tongue may be inserted into the plug-in sleeve, for example, wherein a good contacting within the plug-in sleeve is enabled due to forming a sheathing portion 21.

[0088] The housing 20 further has a first housing portion 22 surrounding the second connecting element 12 at least in portions. Preferably, the first housing portion 22 really surrounds the second connecting element 12 only in portions.

[0089] At an outer surface of the housing 20, a guiding device 23 for guiding the housing 20 during assembly in parallel to the plug-in direction S is formed. In the represented example, the guiding device 23 is formed at the housing bottom side 40.

[0090] As can be well recognized in FIG. 4 in a side view, the guiding device 23 is formed to be substantially wedge-shaped. Due to the bevelled surface of the wedge-shape, the housing 20 of the plug-in coil element 10 can be mounted simply and be pushed onto an electrical connecting element. The guiding device 23 may in particular be pushed onto a bridge-like contact part 6 of an electrical connecting element 7 (see FIG. 5).

[0091] In addition, an arresting device 24 for arresting the housing 20 in parallel to the plug-in direction S is formed. In the present case, the arresting device 24 is located upstream of the guiding device 23 in the plug-in direction S.

[0092] The arresting device 24, for example, is formed as a stop element or a stop surface. When the arresting device 24 correspondingly rests against a counter element, further pushing of the housing 20 or the plug-in coil element 10 is effectively prevented. In particular a connecting portion 9 of an electrical connecting element 7 (see FIG. 5) may serve as a counter element of the arresting device 24.

[0093] The represented sheathing portion 21 is formed from a shrinking tube material, in particular from polyolefin.

[0094] In the represented exemplary embodiment, the guiding device 23 and the arresting device 24 constitute a common, in the present case, a second housing portion 43.

[0095] At the housing bottom side 40, an attenuation surface 25 is formed for applying an attenuation element 26. The attenuation element 26 is formed from a soft material, preferably from a rubber material or from a felt material.

[0096] The attenuation surface 25 protrudes slightly beyond the housing bottom side 40 so that an assembly or fixing of an attenuation element 26 is enabled in a particularly simple manner. The correct positioning of the attenuation element 26 at the housing 20 thus is secured, since the allocation of the attenuation element 26 to the attenuation surface 25 is clearly obvious.

[0097] In the area between the sheathing portion 21 and the first winding body end 31, a third housing portion 44 is formed. This third housing portion 44 predominantly surrounds the area of the coil wire portion 19. Thus, in particular this coil wire portion 19 is protected by means of the housing portion 44, and this area is mechanically stiffened.

[0098] The winding body 30 is substantially surrounded by the fourth housing portion 41.

[0099] It can be recognized that the housing 20 almost completely surrounds or covers the plug-in coil element 10 by the various housing portions 22, 41, 43 and 44 as well as by means of the sheathing portion 21. Solely the second connecting element 12 is surrounded by the housing 20 only in portions.

[0100] The housing 20 is preferably made of polyamide, and is preferably a plastic moulded part.

[0101] In FIG. 5, a pane 1, in this case a vehicle pane is illustrated. The pane 1 comprises a substrate 3 and an electrically conductive structure 4. The electrically conductive structure 4 is electrically contacted to the electrical connecting element 7. The electrical connecting element 7 substantially comprises a bridge-like contact part 6, two little feet 5, as well as a plug-in connection 8. The plug-in connection 8 is fixed or connected to the bridge-like contact part 6 by means of a connecting portion 9.

[0102] The little feet 5 preferably are connected to the electrically conductive structure 4. This may be performed, for example, by means of a solder connection. It is moreover possible that the connection to the electrically conductive structure 4 is performed by means of an electrically conductive adhesive.

[0103] In FIG. 6, a plug-in coil element 10 connected to the electrical connection element 7, and the associated housing 20 are illustrated. The plug-in connection 8 is inserted into the sheathing portion 21 or the opening 45 of the sheathing portion 21 so that a contact establishment with the plug-in sleeve is performed.

[0104] The guiding device 23 rests against the bridge-like contact part 6, wherein the arresting device 24 abuts against the connecting portion 9, so that a further movement of the housing in the plug-in direction S is prevented.

[0105] The attenuation element 26, however, rests against the substrate (not illustrated). By means of the attenuation element 26, vibration noises are prevented from being generated. Furthermore, the attenuation element 26 serves as a kind of support of the plug-in coil element 10 and the associated housing 20.
