Description

The invention relates to a fastening device, in particular for a motor vehicle antenna according to the preamble of claim 1.

There are already a variety of fastening devices known in particular for motor vehicle antennas on a body opening.

For example, the shows EP 0 758 802 B1 a rod-shaped motor vehicle antenna. At a foot of such a motor vehicle antenna is a threaded sleeve downwards, which can be passed through an opening usually in a motor vehicle body part in the roof area. Through the provided with a longitudinal slot screw an antenna cable is led out laterally. A nut, which can be opened from below, serves to firmly anchor the antenna to the body part.

According to the EP 0 891 002 B1 and the DE 202 04 863 U1 two staggered openings are provided in the body roof, in the Vorveröffentlichung EP 0 891 002 B1 the antenna is fixed by means of a fastening means on the inside of the body and at the second opening in the body part, a pin connected to the antenna base is passed, to which an antenna cable can be connected. The mentioned pin also serves to secure the antenna against rotation on the body, as well as in the aforementioned DE 202 04 863 U1 ,

The above-mentioned antenna mounts have i.a. the disadvantage that always after putting on the body roof from the inside a counter-thread member must be turned onto a threaded pin to ensure the fixation and secure anchoring of the antenna, with partially a second body opening with a pin passed therethrough to achieve a Anti-rotation is necessary.

According to the DE 100 09 978 A1 a Schraubbefestigung is also proposed by means of a so-called central attachment, but with additional two-legged spring elements, the legs are brought together in the direction of insertion of the fastening device in the vehicle opening and so the cross-sectional area of the device protrude that they are introduced into the body opening of a boundary wall of the Be compressed opening and after passing the opening on the vehicle antenna side facing away from the body opening spring back to engage behind the body opening. This allows a pre-adjustment ensure the antenna. Subsequently, the screw member must be placed on the threaded pin and tightened.

An extent comparable or similar fastening device is also from the DE 298 14 054 A1 known.

A fastening device for a vehicle antenna is also from the DE 202 03 914 U1 known. Here, a locking support is used, which is resiliently pre-pressed elastically during insertion of the fastening device by a motor vehicle opening inwardly and springs back after passing the body opening to the outside and / or the edge of the body opening on the opposite side to the base plate or overlaps the foot of the antenna. This embodiment is compared to the aforementioned prior art such that already a screw for holding the fastening device is pre-assembled and rests on a remote antenna to the side of a circumferential annular edge of a locking support. After the pre-assembly described above, the screw is then tightened, with spreitzfähige outer locking support elements come to rest with a stepped shoulder on the body panel and supported there. Through the fastening device itself routed cables are guided, which have no interface in the region of the fastening device.

A fastening device which is largely similar to this prior art is also known from the generic prior art according to FIG DE 10 2005 029 686 A1 known. The fastening device for an antenna comprises in this embodiment, one or more axial connectors, which are formed at the corners of a square or rectangular housing portion of a first fastening device. In the center is a sleeve provided with longitudinal slots, which extends away from the foot part of the antenna. On this sleeve, a second fastening means is placed, which is provided with laterally projecting legs which can be supported on the opposite side to the foot of the antenna side of the body panel when a corresponding screw inserted into a central opening of the second fastening means and at the bottom of the Foot part screwed into a mating thread and fastened there. To make the overall structure of the fastening device at least comparatively compact, projects from the underside of the fastening device, the aforementioned sleeve away from the foot and ends in a more distant plane than the opening or insertion of the exposed connector. Due to the aufzusetzende pot-shaped second fastening means and by einzudrehende herein screw the entire structure of this central portion is still higher and far surpasses the opening and insertion of the connector.

In contrast, it is an object of the present invention to provide an improved device, in particular for a motor vehicle antenna, which preferably provides standardized connectors in the region of the fastening device, for example according to the standardized FAKRA system, while minimizing the assembly and construction volume. Preferably, the mounting hole in the vehicle roof should be as small as possible be designed, which also advantageously the solution should continue to be designed in the manner of a central fastening.

The object is achieved according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

By the invention, a fastening device is provided in particular for motor vehicle antennas in a motor vehicle body, namely at a comparatively small passage opening, and this, although in the context of the fastening device one or more shielded or unshielded, one or more lines comprehensive connector can be provided. The system according to the invention is particularly suitable for the use of standardized FAKRA HF connectors.

In the past, the system of central fastening proved to be advantageous.

In the context of the invention, it is also possible to attach an attachment, in particular in the form of a motor vehicle antenna by means of a "one-hand assembly", ie by means of Vorverrastung example, on the vehicle roof. Separately for handling the components of the antenna attachment such as nuts, screws, clamps, etc., which are not fixed to the attachment to be attached, in particular in the form of the antenna and thus captive, are avoided in the invention.

In particular, in the context of the invention, a central attachment can be realized, which allows a direct contacting by means of a SMD-mountable connector system, preferably in the manner of a multiple FAKRA connector. The arrangement and orientation of the connectors can be designed, for example, to a minimum Achsabstandsmaß required for the insertion of FAKRA individual contacts (of 10 mm, for example), which is the basic for the FAKRA connector system standard (DIN 72594-1 "road vehicles 50 ohms High-frequency interface ") corresponds. The required space is determined by the opposite the plugs larger bushing geometry.

The orientation or alignment of the individual connectors can be such that the individual FAKRA connectors can be plugged in and released independently of one another (with appropriate unlocking and removal).

In the above-mentioned connectors according to the standard FAKRA system a solution comparable to the present invention is not feasible, since there is no more free space for the integration of a central fastening.

This is where the invention starts.

In principle, it could be thought to provide mechanical fasteners to the connectors outboard. However, this would lead to a dramatic increase in the total space required and inevitably to be enlarged mounting hole in the vehicle roof.

In contrast, the invention proposes to provide essential parts for the central attachment (ie in particular the clamping elements for clamping the fastening device) in the region of the mounting opening (in particular a body opening) and / or in a plane and / or an area of the attachment, in particular in shape the vehicle antenna is closer than the plane in which the insertion of the one or more connectors comes to rest. In other words, the insertion opening of the connectors to the attachment, in particular in the form of the motor vehicle antenna, is more remote than the parts which are essential for the central attachment, i. in particular, the clamping elements required for the central fastening and / or threaded member, which acts on the clamping elements.

In an extreme case, according to the invention can even be provided that the essential parts for the central fastening (such as clamping elements, a clamping or locking bracket, etc. and / or a fastening screw) based on the mounting direction at least partially not even protrude through the mounting hole, but only with their Clamping and fastening portions that pass through this mounting hole to engage behind the edge of the mounting hole, whereby the attachment is held. In this case, even the plane defined by the position of the insertion opening of the one or more connectors may come to lie in the immediate vicinity of the plane of the mounting opening. In an extreme case, even the plane defined by the position of the insertion opening of the one or more plug connectors can even be located in front of the mounting opening with respect to the mounting and insertion direction, namely, in particular if, for example a mounting plate or a chassis of the attachment (preferably in the form of the motor vehicle antenna) has a corresponding facing the body surface space or a corresponding chamber for receiving the connector. In other words, the essential parts of the clamping elements, starting from the bottom plate or the chassis of the attachment only in a partial height of less than 90%, in particular less than 80%, 60%, 50%, 40%, 30% and even less than of 20% or 10%, so that the connectors override the central mounting and its corresponding clamping elements many times and the entire space is available when plugging sockets, etc. on the connectors.

In other words, according to the invention, it is proposed according to the invention that the part of the central fastening which is accessible for handling during assembly (i.e., the screw of the central fastening) be moved out of the area of the socket contacts when tightened, which is required in the inserted state of contacts inserted in the contact connectors. Thus, so are the essential for handling part of the central mounting in a lower level compared to the "connector or socket level". In concrete terms, this means that the socket contacts located, for example, on a cable harness can only be plugged onto the plug connectors at the end of the installation of an antenna. However, this corresponds to the usual installation sequence when installing a ribbon roof antenna and ensures the proper installation of the antenna.

The actual required for clamping an antenna mounting parts (for example in the form of elastically deformable Support elements, spring plates and / or clamping pieces) are according to the invention in a plane or in an area that comes to rest in the mounting or plugging direction to the insertion opening of the connector to the total height or at least the axial part height of the connector, namely below the insertion of the connector. Preferably, it is therefore provided that only the fastening screw in the preassembled state before the final tightening with its screw head even more distant to the attachment (preferably the car antenna) and still extends into the range of aufzusetzenden bushes or socket level. However, once the antenna mounting device inserted in the mounting hole in the vehicle roof, pre-locked by the clamping elements and fixed by tightening the mounting screw, the entire insertion height of the sockets to be connected to the connectors is available again. It can be formed, for example, in the form of external longitudinal ribs on the connectors or on the connector connecting the housing or insulating corresponding coding, so that at a particular connector always a matching, mating counter-connector touchdown and thus connectable.

The above-mentioned codes or guides, so the so-called Kodierrippen are doing to a connector preferably from the top side of starting only over a partial height of, for example, at least 3.5 mm of the connector formed, so that here is a sufficient adjustment height for the mounting screw available to remove them from their preassembled state (the insertion of the fastener through the mounting hole allowed in the vehicle roof) to be able to screw to their final mounting position.

Since the above-cited standard for the FAKRA plug-in system defines these coding guides or coding ribs as required only in the upper region of the plug coding housing extending 3.5 mm from the plug top side down to the plug base, such an omission of these geometries is described in US Pat between areas. In the resulting space so the head of the mounting screw can move. In addition, if necessary, a sub-segment of the cylindrical plug coding omitted.

The required Eindrehweg the screw results from the addition of biasing or Verspannbereich the elastically running clamping elements of the central mounting, the compression range of the sealing elements of the antenna between the antenna base and the vehicle outer skin, the difference of the different strengths of the vehicle outer skin to be compensated (or in the clamping region of the vehicle roofs ) and the required path for safe rear locking of the preferably formed in the form of a spring plate clamping elements in Vorverrasten the antenna (whereby the so-called "one-hand assembly" is made possible).

In a particularly preferred embodiment of the invention, the extremely low height of the fastening device, in particular for the motor vehicle antenna, achieved in that the components required for the central fastening partially through corresponding openings in the foot, ie in particular in the base plate or the chassis of the antenna in protrude the interior of the antenna, So in that space between a PCB bottom and the chassis inside.

The spring-elastic clamping elements are preferably formed from metal, for example from a spring plate.

This selection of materials allows the force generated during assembly (for example, the roof antenna) with which the antenna is pulled onto the vehicle roof to be kept virtually constant, regardless of thermal or mechanical environmental influences (which affect the antenna or mechanical fastening in the course of the vehicle's life cycle) become. This distinguishes the fastening device according to the invention compared with the prior art previously known solutions, in particular those solutions in which components are used for the fastening or biasing elements made of plastic, the yield over time of material aging in conjunction with the above-mentioned environmental influences the contact pressures (thus creating a relaxation of the clamping elements). As a result, namely the contact pressure of the motor vehicle antenna to be fastened on the vehicle outer roof and thus also the sealing effect of the existing sealing elements would diminish.

In the context of the invention, a further preferred embodiment is possible, which takes into account the requirement for captive components of the central fastening. This is achieved in a preferred embodiment of the invention in that the individual components of the attachment (such as, for example, consisting of a spring plate clamping elements, plungers or pressure screws, etc.) positively connected to each other or by screwing The screw are movable, but inseparably connected to each other.

In a particularly preferred embodiment of the invention also proves to be advantageous that a used Umoder coding housing (for example, the FAKRA standard) in the manufacturing process after mounting the fasteners is snapped onto the connectors, so that the underlying central mounting even when loosening of the screw member can not fall out. This is especially true when using the above-mentioned FAKRA connector system.

It also proves to be particularly favorable that different possibilities of central fastening can be realized.

Thus, it is possible in the context of the invention according to a preferred embodiment, to use a clamping device that is formed and shaped by the material used, the material thickness, the material shaping, etc., that it meets the inherent requirements for a rest and / or or clamping element fulfilled. These requirements include on the one hand to provide a tensioning device, which includes a rather soft or elastic component for reducing the contact force required for mounting the antenna Vorverrasten the antenna in an anchoring opening (for example, body opening) on the vehicle roof, and on the other hand one rather hard and stable component (to transfer the required high force) during final assembly for bracing the antenna on the vehicle roof. Here it has been shown that in particular by a suitable geometric design these requirements can be taken into account.

If, on the other hand, even higher contact forces for fastening the fixture, in particular in the form of the antenna, would be necessary (in which an acceptable compromise between elasticity and hardness due to the geometric design of the fixture, preferably in the form of a spring plate, for example, by embossing with the formation of points of increased rigidity and on the other hand Elastic sections is not possible), these increased external forces are achieved by the use of an additional pressure piece, which cooperates with the rather elastic clamping means.

Hereinafter, a first embodiment of a fastening device according to the invention for an attachment 1 is explained in particular in the form of a motor vehicle antenna 1 ', which is to be mounted on a mounting opening 3 in a mounting wall 5, preferably in the form of a body panel 5'.

This is in FIG. 1 in a schematic, spatial representation of the vehicle antenna 1 'partially shown, with a housing or hood 7, below which a mounting plate or a chassis 9 is provided, which is sealed by the hood 7. Inside the necessary electronics is housed, with an upwardly further uplifting part of the housing cover 7 is omitted in the drawing, within which one or more antennas or antenna devices are accommodated in addition, and further protrude upwards.

In FIG. 2 a schematic bottom view is shown after installation, wherein the border or seal of the chassis or provided in the outer edge region seal 11 is indicated, which is not visible from the underside of the body panel 5 'per se. Through the mounting hole 3 passes through a connector assembly 13 with, for example, a plurality of connectors 15 with associated connector housing 15 ', in the illustrated embodiment, four connectors 15, which are arranged at the corners of a rectangle. This may be shielded coaxial, but also to unshielded cables, these connectors may have one or more lines or inner conductor. Restrictions are not given in this respect.

In FIG. 3 is a corresponding illustration too FIG. 2 reproduced, but here are still mounted cable coupler, which is hereinafter also partially referred to as a coded cable coupler housing 19. In this embodiment, cross-protruding cable connections 20 are provided on the cable couplers 19, but which need not be provided.

Preferably, the connectors 15 may be connectors that meet the FAKRA standard. In this respect, it may be an SMD-mountable FAKRA plug-in system 17, which fulfills the mentioned plurality of plug connectors 15 in accordance with the DIN standard 7254994-1 "Road Vehicles 50 Ohm High Frequency Interface". This system is designed to plug in FAKRA single contacts with a minimum required center distance of 10 mm.

A corresponding representation to FIG. 1 in vertical section is based on FIG. 4 played. There is also the mounting plate or the chassis 9 in section along with the body panel 5 'facing plastic sheath and / or sealing 10 can be seen.

The following will be on FIGS. 6 ff., which illustrate the fastening system in greater detail.

In FIG. 6 is in part again the wall, in particular in the form of the body panel 5 'with the mounting hole 3 shown. Of the attachment, preferably in the form of the motor vehicle antenna 1 ', only a section of the mounting plate or the chassis 9 is reproduced, in which or in which the mentioned plug-in system 17 is mounted and mounted.

From the other illustrations, the further structure and the assembly process is shown in detail.

As in particular from the representations according to the FIGS. 7a and 7b can be seen, the fastening device comprises a fastening screw 21, the threaded shaft 21a is screwed into a threaded hole 9a in the chassis 9. This threaded hole 9a is provided with a corresponding internal thread and comprises a receiving space, in the illustrated embodiment in the form of an opening 9 passing through the mounting plate into which the shank of the fastening screw 21 is screwed. In order to ensure a sufficiently tight fit, the mounting plate 9 is provided in this area with a projecting away from the mounting wall 5 sleeve-shaped extension 9b.

Further, in the mounting plate 9 in the embodiment shown for fixing screw 21 opposite (offset by 180 ° to each other) openings 23 are provided.

How out FIGS. 7a and 7b can be seen, a clamping or locking device 25 is also provided, which is also referred to below as a spring plate or spring clip. This spring plate or spring clip is in more detail FIGS. 11 and 12 to see. It can be seen that this clamping or latching device 25 comprises a central portion 25 a, which is provided with an opening 25 b, through which the mentioned fastening screw 21 is inserted. Opposite to the central opening 25b clamping and locking portions 25c are provided, which are opposite to the insertion according to the arrow 29 aligned divergent.

These clamping and latching portions 25c are connected via a double V-shaped, S- or Z-shaped spring construction 25d with the central portion 25a, so that in other words the central portion 25a via a first in the direction of attachment 1 leading bend 31a in a subsequent leg portion 31b, and this over a subsequent bend 31c (which forms almost a 180 ° deflection) merges into an adjacent leg portion 31d, at whose free end then a repeated, again again an almost 180 ° deflection resulting bend 31e is formed which terminates in a clamp rest portion 31f.

Adjacent to the opening 25b in the so-called spring plate or spring clip 25 'is in the illustrated embodiment a funnel-shaped recess 25e is provided whose shape corresponds to the underside of the screw head 21b of the fastening screw 21, which here has a conical taper from the transition from the screw head to the screw shaft. In order to ensure sufficient stiffening on the one hand or else a desired elasticity on the other hand at different sections of this tensioning and / or locking device 25, longitudinal ribs and / or depressions 25g or other impressions and / or measures can be provided, for example in the region of the middle section 25a. In order to ensure a higher elasticity in the region of the clamping feet 31 thus formed (which are also sometimes referred to as clamping and support elements), here a middle material portion is provided with a recess 31h, wherein a part of the punched material as the above, ie from the Clamping and support section 31f projecting web 31j formed.

As shown FIGS. 7a and 7b is the attachment 1 in the form of the vehicle antenna 1 'before its pre-adjustment and attachment in the mounting hole. 3

Based on FIGS. 8a and 8b It is shown how, during further insertion corresponding to the mounting or insertion direction 29, the outer clamping and / or ramp surfaces 31f, which converge towards one another in the insertion device, accumulate on the edge 3 'of the mounting opening 3. Upon further impressions of the fixture 1 with the fastening device these clamping and / or casserole sections 31f are pressed by the edge 3 'of the mounting hole 3 further inward in the direction of fastening screw 21, namely by increasing the clamping forces, since the leg sections 31b and 31d are increasingly pressed towards each other.

During the further insertion movement of the edge 3 'slides along the clamping and / or ramp surface 31f until the trailing edge 31i of this clamping and / or Aufflageabschnitte the edge 3' of the mounting hole 3 passes and then by the elastic clamping forces of the fastening device, the clamping and / or support sections 31f spring back outwards, as shown by FIGS. 9a and 9b is shown.

Thus, the requirement for a one-hand assembly is met, since after passing through the fastening device thus constructed and the engaging behind the mounting hole 3 by clamping and support portions 31 f, the vehicle antenna 1 'captive in the mounting hole 3 in the vehicle body. 5 'is held.

Now, the fastening screw 21 is tightened with a suitable tool, for example in the form of a screwdriver, to stop, as shown by Figures 10a and 10b is shown. In this case, the trailing edge 31i comes with the lower or inner side 5a of a motor vehicle interior of the body panel 5 'in contact, and indeed already at a time when the fastening screw 21 is not fully screwed. With further tightening of the fastening screw 21, the middle portion 25a of the spring plate or spring clip 25 'is then moved increasingly towards the underside of the mounting plate 9, whereby increasingly higher clamping and tensioning forces on the clamping feet 31 and the clamping support formed by the trailing edge 31i, the are supported on the underside of the mounting wall 5. In this position, the fastening device is then held firmly and unverrutschbar.

After tightening the fastening screw 21, the downwardly facing upper side of the fastening screw 21, i. the screw head 21b to lie in a plane 41, which is again significantly closer to the mounting plate 9 and the mounting wall 5, so their distance is even greater to the plane 43 which is formed by the insertion opening 15a of the connector 15.

After tightening the screw 21 for firmly anchoring the vehicle antenna in the mounting hole 3 can then be attached to the connectors 15, the aforementioned cable coupler 19 below, with sufficient space for this is available without the fastener with the clamping and / or latching device 25 and the fastening screw 21 would adjust the necessary mounting space.

In order to ensure on the one hand sufficient elasticity for the spring plate or the spring clip 25 'comprehensive clamping device on the one hand, but also to ensure that when tightening the fastening screw, the high locking forces are fully effective as possible, by means of the fastening device according to the invention the attachment in question to hold and fix, according to a modified embodiment of the FIGS. 13 and 14 shown that in addition to the actual spring plate or spring clip 25 'still an additional pressure member 125 may be additionally provided.

The pressure member 125 also has a central portion 125a with a central opening 125b, followed by two opposing pressure sections or pressure arms 125c which merge into a subsequent bend 125d and subsequent pressure-transfer arms 125e angled toward the mounting plate. The end of these pressure transmitting arms 125f comes to lie between the two leg portions 31b and 31d of the clamping feet 31 of the spring plate or spring clip 25 '.

In this embodiment, the clamping feet 31 may be configured with their leg sections and bends by appropriate choice of material, shape, etc., so that here the elastic deflection movement when placing the fastener, so when passing the clamping support portions 31 f through the mounting hole 3, lighter generating less Spring forces takes place. When tightening the fastening screw 21 but then come the ends 125f of the pressure member 125 between the respective leg portion pairs with the leg portions 31b and 31d at the intermediate bend 31c to the system, so that in the course of locking movement of the locking screw increasingly larger contact forces on this bend 31c exercised and thus opposite to the mounting direction 29, the leg portions 31d leading to the clamping support portions 31f are increasingly tensioned in the tightening direction.

By such a construction, the specification of a corresponding elasticity and the highest possible transmission of compressive or tensile forces on the clamping sections can be taken into account.

In FIGS. 15a and 15b while the situation is shown with a spring clip 25 'with an additional pressure member 125 prior to assembly, whereas in FIGS. 16a and 16b the situation is then reproduced after the final pre-adjustment in the mounting opening 3 and the subsequent tightening of the screw 21. In this situation, pressure forces in the direction of the motor vehicle antenna are then exerted by the pressure member 125 through the ends 125f on the bend 31c of the spring clip 25, via which the subsequent edge 31d and the clamping and support sections, the subsequent edge 31i to the underside of the body panel 5 'is pressed with higher contact forces.

Based on FIGS. 17 and 18 In this respect, an alternative with respect to the last-explained embodiment is shown, in which the clamping feet 31 are formed in a modified manner. These clamping feet 31 are formed in this embodiment substantially only V-shaped or U-shaped or similar thereto, wherein the actual clamping and support portion 31f not a repeated reverse bending to the bend 31c includes, but here transversely to the thigh plane projecting clamping lugs 31k are formed, the clamping or support portions 31f come with their clamping edges 31i on the underside of the mounting wall 5, so on the underside of the body panel assembly 5 'adjacent to the mounting hole 3 to the plant. In that regard, further modifications are possible.

After installation, ie after tightening the mounting screw 21, the entire height of the connector is then available for contacting with the aufzusteckenden cable coupler or correspondingly shaped other complementary connectors, without the explained fastening device so far contributes to an increase in the installation space. Thus, then in the FIGS. 1 . 3 and 5 shown cable coupler are plugged onto the connector housing 15 ', which are held captive by corresponding tabs and depressions on the connector housing 15'.

An overall low overall height can also be realized according to the invention by virtue of the fact that the clamping feet 31 comprise one or more bends which are designed such that they protrude through an opening or openings 23 in the mounting plate or in the chassis 9, ie opposite to the mounting direction Protrude 29, and possibly protrude through the mounting hole 3, so that the clamping edges 31i can lie at least approximately in the amount of the central portion 25c of the spring plate or the spring clip 25 '. In an extreme case, even the central portion 25c may be more remote from the plug-in opening of the connectors, even on the side of the body panel on which the attachment 1 is positioned so that substantially only the clamping edges 31i pass through the mounting aperture and engage behind the mounting aperture to support on the mounting wall 5. Through this design of the clamping feet, even the middle part of the spring plate or the spring clip 25 'considered in the insertion direction not only lower than the clamping edge 31i, but even with respect to the plug 29 even come to rest, so even on the opposite side to the with the Mounting opening 3 provided mounting wall. 5

Finally, it is pointed out that the pressure part 125 can also be provided with an internal thread, so that the pressure member 125 is held captive to the screw with the spring plate or the spring clip 25 'when screwing the screw, so it can not slide off the screw shaft.
