Description

The invention relates to a device for positionally fixing an antenna assembly to a surface having a recess for antenna connection means formed as plugs or sockets, wherein the antenna assembly has a bottom plate from which connecting means to the recess extending, which secured against loss clamping plate and a screw or a bolt comprise such that the clamping plate by means of screw or bolt in the direction of the base plate is movable and braced, according to the preamble of claim 1.

From the DE 10 2005 044 618 A1 a roof antenna is previously known, which has a bottom plate for receiving antenna elements. The antenna elements are covered by a connectable to the bottom plate antenna cover. The previously known roof antenna should be mounted on a cutout, in particular a roof opening having mounting surface, in particular a vehicle roof by means of screw.

According to the DE 10 2005 044 618 A1 the connecting means are formed as an axially and radially movable clamping part between the bottom plate of the roof antenna and the mounting surface. The actual attachment is therefore by means of bracing, preferably by screwing. The fastening process is realized via an initially axial and then radial movement of the clamping part. By turning the screw, the distance between the clamping plate and the bottom plate can be changed with the result of the desired attachment and pinching corresponding portions of the roof of the body of the vehicle. The known clamping part has an outer contour, which makes it possible to pass this when placing the roof antenna through a corresponding roof opening in the mounting surface and then bring by twisting or moving the clamping part by a defined amount of this under the mounting surface into engagement, so that the clamping part is not can be removed again against the direction of insertion from the roof opening. In this aspect, should be particularly triangular, oval, elliptical or other polygonal or wedge-shaped outer contours of the clamping part are suitable.

The necessary in the prior art, first axial and then radial movement of the clamping part requires a precise rule of action, which is disadvantageous in a generally fast and speedy installation. In addition, a radial movement, in particular a rotation of such a configured roof antenna on a vehicle body with the risk of damage to the body surface, in particular a there already applied paint layer is connected.

From the German utility model DE 20 2013 010 506 U1 is a generic device for positionally correct mounting an antenna assembly known.

In this prior art, it is an object to handle the attachment process using a simple, quasi-intuitive movement routine, so that reduces the assembly effort and thereby a time and cost savings result. In this regard, the width of the recess is according to DE 20 2013 010 506 U1 at least in sections substantially equal to the width of the clamping plate for fixing the antenna. In addition, the length of the recess is smaller than the length of the clamping plate such that a circular arc-shaped immersion of the connecting means, ie the clamping plate and the screw or the bolt into the recess and a subsequent bracing can be realized. The mentioned arcuate immersion with the clamping plate first into the recess followed by moving into the recess and moving counter to the immersion in the sense of pivoting back can be completely contactless relative to the surface of a body in which the recess is made.

In the solution of the described prior art, however, it is disadvantageous that the connection means for the antenna must be passed through the clamping plate. In this respect, the clamping plate, the space for the connection means quasi covering, formed. Although with such a solution, the size of the recess, which must be introduced into the body surface, be limited, but a reduced stability of the clamping plate itself and a limited number of the execution of connecting elements, in particular sockets or plugs the result.

From the above, it is therefore an object of the invention to provide a further developed device for positionally correct fastening of an antenna arrangement on a surface which has a recess for antenna connection elements, designed as plugs or sockets and / or cables, on the one hand again an intuitive fast safe and simple implementation of the mounting sequence can be realized and at the same time the largest possible area for the arrangement of the necessary antenna connector plugs, sockets or cables is given, and the clamping plate can safely accommodate the necessary forces for fixing the antenna even with a possibly smaller clamping surface for wiring.

The object of the invention is achieved by a device according to the feature combination according to claim 1 or 8, wherein the dependent claims comprise at least expedient refinements and developments.

It is therefore assumed that a device for positionally correct fixing an antenna assembly to a surface, in particular a body of a vehicle, which has a recess for the necessary antenna connection means. These antenna connection means are preferably designed as plugs or sockets, in particular as so-called FAKRA connectors, or connection cables.

The antenna arrangement has a bottom plate, from which connecting means extend in the direction of the recess. These connecting means comprise a secured against loss clamping plate and a screw or a bolt or the like means such that the clamping plate by means of screw or bolt in the direction of the bottom plate is movable and braced. About this tension fixing the antenna assembly on the aforementioned vehicle roof or the like surface is effected.

The antenna has an antenna housing, which is preferably designed in the form of a so-called shark fin or similar streamlined. Usually, the antenna housing and the entire antenna arrangement has a longitudinal axis, which runs parallel to the vehicle longitudinal axis in the assembled state. The extent of the antenna arrangement or the housing and the bottom plate is realized such that the length dimensions are greater than the width dimensions, so that on the one hand the different antenna configurations can be accommodated and united for different frequency bands in the housing and on the other hand the necessary streamlined shape to avoid wind noise is guaranteed.

In the device according to the invention it is assumed that the connection means as plugs, sockets or cables, z. B. FAKRA sockets are executed. This means that after mounting the antenna on a vehicle roof care must be taken that the connection means, in particular the FAKRA sockets, are freely accessible from the rear or below, in order to realize the necessary connections. This also applies to the necessary power supply for normally active antennas.

According to a first embodiment of the invention, the width of the recess to be executed in the vehicle roof is smaller than the width of the clamping plate, with the aid of which the antenna is fixed. The length of the recess, however, is greater than the length of the clamping plate such that a lateral einschwenkendes immersion of the connecting means with clamping plate in the recess and a displacement in the direction of the longitudinal axis of the recess and the subsequent bracing can be realized.

When reached position-appropriate mounting position then a group of plugs or sockets of the antenna connection means is located within the recess and freely accessible.

In a further development of the invention, the plug or socket in a first region of the bottom plate and it is the clamping plate with screw or bolt in a laterally spaced from the first plate region second region of the bottom plate formed such that the desired free access to the connection means is present.

Thus, the area of the arrangement of the connection means is separated from the area of the clamping plate and spaced apart. A superimposition of these two areas with the disadvantages described above is avoided. At the same time there is a larger space for the formation of connection means, d. H. Bushings and / or plugs available, which is due to the fact and requirement that the number of antennas to be housed in the antenna housing with appropriate connections due to a variety of wireless communication solutions is subject to a constant increase.

In a preferred embodiment of the invention, the recess in the mounting surface, in particular a vehicle body, is formed as a slot or has a slot shape, wherein on the longitudinal axis of the slot the recess merges into a subsequent opening for a twist protection or the recess is a spaced Associated opening for a known twist.

In the embodiment with adjoining the recess opening is caused by the aforementioned displacement in the direction of the longitudinal axis of the recess, in this case specifically in the direction of the subsequent opening, the desired Verdrehschutz and it can with reaching the realized through the opening stop then screwing be carried out with the desired deadlock.

In an embodiment of the invention in the first region of the bottom plate, extending in the direction of recess extensions for Vorverrastung and Fehlsteckschutz provided, wherein the extensions are formed so that selbige at least in sections of the contour of the hole pattern, in particular the oblong hole recess are approximated or approximate this contour.

In a development of the invention, the first region of the base plate has two spaced-apart partial regions, the second region of the clamping plate being formed in the spacer space. In this case, the recess has a hole pattern in oblong shape with sidecut. In the described further embodiment, the clamping plate is positioned in the fastening state in the region of the sidecut.

In a second embodiment of the invention is assumed that a substantially circular recess which has a predetermined diameter.

In the second embodiment of the invention, the clamping plate is longer than the diameter of the recess by a predetermined amount. By contrast, the width of the clamping plate is smaller by a predetermined amount than the diameter of the recess.

The resulting hereby lateral gap between the clamping plate and recess serves to accommodate connection cables or also connection sockets.

On the mounting side, in this second embodiment of the invention, the cables are initially led with or without plug through the hole pattern. Thereafter, the antenna assembly is angled with clamping plate in Klemmplattenlängsrichtung and guided on one side through the hole pattern. The degree of greater relative to the diameter of the recess length of the clamping plate determines the degree of angling to the one-sided lead through the hole pattern. In the next step, after swinging in and completely pushing the clamping plate, the antenna is slightly pushed back against the direction of insertion. This takes place until the antenna arrangement is seated and an optional anti-twist device engages in a further recess in the vehicle roof. Thereafter, the tightening of the clamping plate by means of screw or bolt in the direction of the bottom plate until the desired clamping and frictional connection is present.

In a related development of the invention, there is the possibility that the clamping plate has recesses on its longitudinal sides, which receive and lead the connecting cables at least partially. Thus, in this embodiment, it is not necessary to reduce the width of the clamping plate completely by the amount of connecting cable leading to, since at least a partial cross-section of the corresponding cable is received by the respective recess in the clamping plate.

The invention will be explained below with reference to an embodiment and with the aid of figures.

12 to 16 an assembly procedure according to the second embodiment.

The antenna arrangement shown in the embodiments proceeds from a mounting surface 1 , in particular a vehicle roof. The mounting surface 1 has a recess 2 for antenna connection means 10 on.

In the example shown find in the recess 2 six FAKRA plug installation space.

Starting from the antenna base or a base plate 3 are elements for misfire protection and Vorverrastung carried out in a conventional manner.

In a range different from that of the antenna connection means 10 is laterally removed, there is a clamping plate 6 with screw or bolt 7 , About the screw or the bolt 7 is the clamping plate 6 towards the bottom plate 3 , ie in the direction of the antenna housing, can be moved and clamped around the antenna arrangement in a clamping manner on the surface 1 to fix.

In a preferred solution according to the 1 to 10a) is the width B of the recess 2 smaller than the width of the clamping plate 6 , The length L of the recess 2 is greater than the length of the clamping plate 6 in such a way that a einschwenkendes immersion of the connecting means with clamping plate 6 in the recess 2 is possible, wherein when reached, positionally correct mounting end the group of plugs or sockets 10 the antenna connection means within the recess 2 located and freely accessible, in particular the 1 and the 9 demonstrate.

The process of pivoting with moving and fixing is based on the 2 to 9 be explained.

The antenna arrangement is according to 2 above the hole pattern, ie above the recess 2 positioned. The next step is according to 3 a pivoting with immersion of a first clamping plate end in the recess 2 , Following in it becomes according to 4 the clamping plate in the tilted or angled state laterally through the recess 2 pushed. Thereafter, the clamping plate is based on the 4 opposite side (see 5 ) through the recess, ie guided by the hole pattern.

Now is according to 6 the clamping plate 2 , which is larger than the recess with corresponding hole pattern, completely below the surface 1 located. It is then made a displacement of the antenna assembly in the direction of the longitudinal axis of the recess, and indeed until the end position with a view of the recess 2 subsequent opening 12 , which is almost a continuation of the recess is reached. By moving the antenna arrangement in the direction of the surface 1 results in a Vorverrastung and first fixation.

Now you can use the screw or the bolt 7 be pressed, and that until the clamping plate 6 in contact with the underside of the surface 1 reaches, so that sets the desired surface pressure and thus attaching the antenna assembly.

The fixed state with tightened clamp 6 is in the 9 shown.

The basic embodiment of the recess 2 in the form of a slot-like hole pattern is in the 10a) shown. This form of the hole pattern is preferably used in the original equipment or the motor vehicle manufacture according to the assembly of a corresponding antenna. The hole pattern according to 10b) can be used for retrofit purposes. The given in this case circular recess is easier to carry out in the retrofit case by workshops or laymen. Possible disadvantages of a slightly longer period when swiveling in and finding the exact position with respect to clamping plate and its location below the surface 1 can be accepted.

The hole pattern according to 10b) turns out to be a circular hole pattern 2 dar. Distances from the circular hole pattern 2 is a smaller, here also exemplary circular recess 12 for receiving an anti-rotation nose, which extends from the bottom plate of the antenna assembly in the direction of fastening surface.

The operation of mounting the antenna device according to the second embodiment of the invention will be described later with reference to FIGS 12 to 16 explained in more detail.

The 11a) to c) demonstrates a further embodiment of the embodiment of the device according to the invention, wherein it is also ensured that where the clamping plate 6 is executed, there is no hindrance to the accessibility of sockets for antenna connection means.

The recess 2 according to 11a) also has the shape of a long hole from the basic structure, but with a sidecut 14 almost in the middle area.

There, where the sidecut 14 the recess 2 is executed, comes in the assembled state (see 11b ) and c)) the clamping plate 6 at the bottom of the mounting surface 1 for lying.

It therefore has the solution according to the 11a) to c) the first area of the bottom plate 3 the antenna array on two spaced portions, wherein in the distance space of the second area with clamping plate 6 is trained.

Basically, the hole patterns for the standard equipment or for retrofitting in the aftermarket business are the same in terms of size. In series production use, the entire antenna is pivoted in view of the features according to the invention as explained above. When retrofitting an antenna, this is not possible. In this case, the clamping plate or nut and screw is disassembled and placed the antenna on the recess and then screwed. With a single antenna configuration all hole patterns can be used. With regard to the series assembly is to be noted that mounting without pivoting movement is not possible. The antenna arrangement is usually mounted or pivoted on the shortest side of the bottom plate to the attachment center point. By this solution, in principle, the recess can be kept small and the screw for fixing short, as this does not protrude too far into the passenger compartment when mounted outdoors or in the housing when mounted inside. A positive side effect is also that the height of the housing can be reduced, resulting in weight reduction and material savings.

With the help of 12 to 16 let the assembly process according to the second embodiment of the invention are explained in more detail.

An antenna arrangement 13 should be on a mounting surface 1 be mounted, for example, a vehicle roof.

The antenna connection means 10 are designed here as a cable, at the ends are not shown plugs or sockets.

According to 12 The cables pass through a circular recess 2 (see also 10b) ) guided.

In the next step, the antenna arrangement is angled 13 , where the clamping plate 6 the angling follows. In this way, the clamping plate in the recess 2 be swung in ( 13 ).

The longitudinal extent of the clamping plate 6 is by a defined amount greater than the diameter of the circular recess 2 ,

After according to 14 the clamping plate 6 with the help of the pivoting and Anwinkelungsbewegung completely through the recess 2 guided, the entire arrangement is pushed through the hole pattern ( 15 ).

It can be seen from the figures that the narrow design of the clamping plate 6 enough space between clamp 6 and recess 2 remains to the antenna connection means 10 take.

The width of the clamping plate 6 So is for mounting in the recess 2 with a circular cross-section smaller than the diameter of the recess 2 selected.

In addition, the clamping plate 6 on their long sides where the antenna connection means 10 abutment, have recesses, z. B. such recesses, the cross-sectional area of the respective connection means 10 are adjusted. This results in a further guidance and secure fixing of the connection means, so that damage to them in later operation, for. B. caused by metal edges in the recess are excluded.

After successfully pushing the assembly through the recess, the bottom plate comes 3 the antenna arrangement 13 on the top of the mounting surface 1 for lying.

A Arretierungsfortsatz, z. B. formed as a nose 15 , extends from the bottom plate 3 in the direction of a locking opening 12 , so that the desired rotation is given. If the position according to 16 is reached, then using the bolt 7 the antenna arrangement 13 braced.
