Description

Technical Field

[0001] This patent application relates to a vehicle roof antenna and a method for installing a vehicle roof antenna. Background Art

[0002] Roof antennas for mounting on the roof of a motor vehicle are known in the prior art. Many known roof antennas require access from both the upper and lower sides of the roof for installation. However, access from the underside of the roof is often complicated by the presence of decorative strips mounted on the underside of the roof. Summary of the Invention

[0003] The present invention is based on the problem of providing a roof antenna. Another problem of the present invention is to provide a method for installing a roof antenna. These problems are solved by a roof antenna and a method having the features of the independent claims. Various developments are set forth in the dependent claims.

[0004] A roof antenna includes an antenna base having a base plate, a main shaft, a driver arranged on the main shaft, and a locking element. The locking element has two branches, each with a latching hook. The branches extend through holes in the base plate. Translational motion of the driver on the main shaft is converted into displacement of the locking element in a direction perpendicular to the base plate. The roof antenna can advantageously be mounted on the outside of the vehicle roof, without requiring access from the inside. This is achieved by enabling the antenna base of the roof antenna to be locked to the vehicle roof via the locking element. In this case, the locking element can be locked from the outside of the vehicle roof via the main shaft and the driver.

[0005] In an embodiment of the roof antenna, the branches of the locking element can be elastically expanded by a translational movement of the actuator on the main axis. Advantageously, the expansion of the branches of the locking element supports the locking of the antenna base to the vehicle roof. This provides the particular advantage that, as long as the branches of the locking element of the roof antenna are not expanded, the antenna base of the roof antenna can be particularly easily arranged in the mounting hole in the vehicle roof. The subsequent expansion of the branches of the locking element allows the antenna base of the roof antenna to be stably anchored in the mounting hole.

[0006] In one embodiment of the roof antenna, the actuator is arranged between the branches of the locking element. This advantageously results in a particularly simple construction, wherein a translational movement of the actuator on the main axis can be converted into a displacement of the locking element in a displacement direction. The arrangement of the actuator between the branches of the locking element advantageously and in a particularly simple manner allows the branches of the locking element to be elastically opened by the translational movement of the actuator on the main axis.

[0007] In one embodiment of the roof antenna, the actuator has two pins. In this case, each branch of the locking element has an elongated hole. In each case, a pin is guided in each elongated hole. Advantageously, the actuator and the locking element are coupled to each other via the pins guided in the elongated holes of the locking element, so that the translational movement of the actuator is converted into a displacement of the locking element in a displacement direction. In this case, the relationship between the translational movement of the actuator and the displacement of the locking element can be advantageously determined by the orientation of the elongated holes and the direction of the translational movement of the actuator.

[0008] In an embodiment of the roof antenna, the longitudinal direction of the main shaft forms an angle of less than 90 degrees with the longitudinal direction of the elongated hole and with the displacement direction. In this case, the longitudinal direction of the main shaft determines the direction of the translational movement of the actuator. This alignment of the longitudinal direction of the main shaft, the longitudinal direction of the elongated hole, and the displacement direction advantageously ensures that the translational movement of the actuator is reliably converted into a displacement of the locking element in the displacement direction.

[0009] In an embodiment of the roof antenna, the branches of the locking element, in an unstressed state, are arranged such that the spacing between the branches is smaller at the first longitudinal end of the elongated hole than at the second longitudinal end of the elongated hole. Advantageously, this constitutes a simple design option for achieving elastic expansion of the branches of the locking element by translational movement of the actuator on the main axis. In this case, the actuator presses the branches of the locking element apart as it moves from the second longitudinal end of the elongated hole in the direction of the first longitudinal end of the elongated hole.

[0010] In one embodiment, the roof antenna has a cover. In this case, the spindle, driver, and locking element are arranged between the base plate and the cover. The cover has a hole through which the spindle can be inserted. Advantageously, this access to the spindle allows the antenna base of the roof antenna to be locked from the outside to the mounting hole in the vehicle roof. To this end, the spindle rotates, translating the driver and thereby displacing the locking element in the displacement direction.

[0011] In one embodiment of the roof antenna, a socket with an inner wall is arranged in a hole in the cover. In this case, the roof antenna includes a plug with an outer wall and a rod. The plug can be arranged in the socket. The rod can be screwed into the plug. Advantageously, the hole in the cover of this roof antenna is also used to secure the rod.

[0012] In an embodiment of the roof antenna, a first spline shaft profile is formed on the inner wall of the socket. A second spline shaft profile, which mates with the first spline shaft profile, is formed on the outer wall of the plug. Advantageously, the first and second spline shaft profiles provide anti-twist protection for the plug when placed in the socket. This allows the rod to be screwed into the plug without the plug rotating in the socket.

[0013] In one embodiment of the roof antenna, at least one O-ring is arranged on the outer wall of the plug. Advantageously, this seals the hole in the cover relative to the surrounding area of ​​the roof antenna. This ensures that the roof antenna remains adequately sealed even when the rod is removed, for example, in a car wash.

[0014] In one embodiment of the roof antenna, the plug has a securing ring that locks the plug in its socket when the rod is screwed into the plug. Advantageously, this prevents the rod and plug from being accidentally removed from the socket when the plug is placed in the socket and the rod is screwed into the plug. At the same time, the plug can be removed from the socket when the rod is not screwed into the plug. Consequently, the roof antenna can be disassembled.

[0015] In one embodiment of the roof antenna, the antenna base has at least one plug connector that is accessible through a hole in the base plate. This plug connector enables electrical contacting of the roof antenna. Advantageously, electrical contacting of the roof antenna can be made before the antenna base is positioned and locked onto the mounting hole in the vehicle roof.

[0016] A method for installing a roof antenna of the type described above includes the steps of: positioning the antenna base over a mounting hole so that the legs of the locking element extend through the mounting hole; and rotating the spindle to displace the locking element via an actuator so that the latching hook of the locking element abuts against an edge of the mounting hole. Advantageously, this method allows the roof antenna to be installed without requiring access from the opposite side of the mounting hole.

[0017] In an embodiment of the method, it further comprises the steps of arranging the plug in the socket and screwing the rod into the plug. Advantageously, as a result, the hole in the cover of the roof antenna is sealed and the roof antenna is completely mounted.

[0018] In an embodiment of the method, the method comprises the following step: before arranging the antenna base over the mounting hole, connecting at least one cable to at least one plug connector of the roof antenna. Advantageously, this enables electrical contacting of the roof antenna. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 A slightly schematic, partially sectional side view of a portion of a roof antenna 10 is shown. The roof antenna 10 can be provided, for example, for mounting on the roof of a motor vehicle. The roof antenna 10 can be provided, for example, for radio reception and additionally or alternatively for transmitting mobile radio signals.

[0032] Figure 1 A portion of the antenna base 20 of the roof antenna 10 and a portion of a roof 40 having a mounting hole 41 to which the roof antenna 10 is to be mounted are shown. The roof 40 may be, for example, the roof of a motor vehicle. The upper side or outer side of the roof 40 is shown.

[0033] Antenna base 20 includes a base plate 100 with a generally planar underside. The base plate can be made of, for example, a plastic material. The base plate 100 can be formed integrally or from a plurality of subcomponents. The base plate 100 includes a hole 110. A sealing ring 120, annularly adjacent to the hole 110, is provided on the underside of the base plate 100. However, the sealing ring 120 can also be omitted. A bracket 130 is formed on the upper side of the base plate 100, opposite the underside of the base plate 100.

[0034] The antenna base 20 also includes a cover 600. The cover 600 can be made of, for example, a plastic material. The cover 600 is arranged on the upper side of the base plate 100 such that the interior area 25 of the antenna base 20 is enclosed between the base plate 100 and the cover 600. The bracket 130 is arranged in the interior area 25 of the antenna base 20. The interior area 25 of the antenna base 20 is accessible through the hole 110 in the base plate 100. The cover 600 also has an hole 610 through which the interior area 25 of the antenna base 20 is accessible.

[0035] The circuit board 200 is arranged in the inner area 25 of the antenna base 20. The circuit board 200 can be formed as a printed circuit board (PCB), for example. The circuit board 200 can have, for example, electrical conductor lines as well as electrical components and structural elements. Figure 1 In the example shown of the antenna base 20 of the roof antenna 10, a first plug connector 210 and a second plug connector 220 are connected to the circuit board 200. However, only one plug connector or more than two plug connectors may also be provided. The first plug connector 210 and the second plug connector 220 extend through the hole 110 in the base plate 100 and are therefore accessible from the outside of the antenna base 20.

[0036] To mount the roof antenna 10 on the mounting hole 41 in the vehicle roof 40, in a first step, the first plug connector 210 and the second plug connector 220 of the antenna base 20 are connected to the first cable 50 via the first plug connector mating portion 51 and to the second cable 52 via the second plug connector mating portion 53. The cables 50, 52 connected to the plug connector mating portions 51, 53 establish an electrically conductive connection with components of the motor vehicle. The cables 50, 52 extend from the vehicle interior through the mounting hole 41 in the vehicle roof 40, making the plug connector mating portions 51, 53 connected to the cables 50, 52 accessible from the outside of the vehicle roof 40. As a result, the first plug connector mating portion 51 connected to the first cable 50 can be connected to the first plug connector 210 of the antenna base 20, and the second plug connector mating portion 53 connected to the second cable 52 can be connected to the second plug connector 220 of the antenna base 20 before the antenna base 20 of the roof antenna 10 is placed on the vehicle roof 40.

[0037] The spindle 300 is arranged in the interior region 25 of the antenna base 20. The spindle 300 is formed as a threaded spindle having a spindle thread 310 (not shown in detail in the figures). The spindle 300 has a longitudinal direction 330 and is retained on the support 130 by a fixing ring 320 so that the spindle 300 can rotate about a longitudinal axis parallel to its longitudinal direction 330. At a longitudinal end, the spindle 300 has a drive profile 360, which can be formed as an internal hexagon, for example. The drive profile 360 ​​of the spindle 300 is accessible from the outside of the antenna base 20 through an aperture 610 in the cover 600.

[0038] The drive 400 is arranged on the spindle 300 . Figure 2 The driver 400 is shown in an enlarged perspective view without the other components of the roof antenna 10. The driver 400 is formed as a spindle nut and has a through hole 430 for this purpose, which has a Figure 2 The internal thread 440 of the driver 400 is formed to mate with the spindle thread 310 of the spindle 300. The driver 400 is arranged on the spindle 300 so that the spindle 300 extends through the through hole 430 of the driver 400. As a result, the rotational movement of the spindle 300 about its rotation axis parallel to its longitudinal direction 330 is converted into a translational movement of the driver 400 along the longitudinal direction 330 of the spindle 300.

[0039] The driver has on its outside a first pin 410 and a second pin 420 colinear with the first pin 410 and opposite the first pin 410. The first pin 410 and the second pin 420 are oriented perpendicularly to the longitudinal direction 330 of the spindle 300.

[0040] also, Figure 1 The locking element 500 is shown arranged in the inner region 25 of the antenna base 20. The locking element 500 is held on the bracket 130 such that the locking element 500 is displaceable along a displacement direction 540 oriented perpendicularly to the base plate 100.

[0041] Figure 1 A cross-sectional view of locking element 500 is shown. Figure 3 The entire locking element 500 is shown in a perspective view without the other components of the roof antenna 10 .

[0042] The locking element 500 comprises an elastically deformable material, such as metal. The locking element 500 can be made of a metal plate, for example. Figure 3 The locking element 500 is shown in an unstressed state 501 , wherein the locking element 500 has not elastically deformed.

[0043] The locking element 500 has a first branch 510 and a second branch 520, which are formed in a mirror-symmetrical manner relative to the first branch 510. The mirror plane is oriented parallel to the displacement direction 540. The first branch 510 and the second branch 520 of the locking element 500 are connected to each other by a connecting portion 550. Starting from the connecting portion 550, the branches 510 and 520 extend substantially parallel to the displacement direction 540. At the latch end 560 of the locking element 500, opposite the connecting portion 550, the first branch 510 and the second branch 520 of the locking element 500 are free. As a result, the locking element 500 has a generally U-shaped basic shape.

[0044] The first branch 510 has a first latching hook 511 at the latching end 560 of the locking element 500. The second branch 520 has a second latching hook 521 at the latching end 560 of the locking element 500. The latching hooks 511, 521 each extend outwardly away from the plane of symmetry of the locking element 500.

[0045] The first branch 510 of the locking element 500 has a first elongated hole 512. Correspondingly, the second branch 520 of the locking element 500 has a second elongated hole 522. The first elongated hole 512 has a first longitudinal end 513 and a second longitudinal end 514. The second elongated hole 522 has a first longitudinal end 523 and a second longitudinal end 524. In this case, both elongated holes 512 and 522 extend along a longitudinal direction 530.

[0046] The first branch 510 and the second branch 520 are not oriented exactly parallel to each other. Instead, a first spacing 531 of the branches 510, 520 measured between the first longitudinal end 513 of the first elongated hole 512 and the first longitudinal end 523 of the second elongated hole 522 is smaller than a second spacing 532 of the branches 510, 520 measured between the second longitudinal end 514 of the first elongated hole 512 and the second longitudinal end 524 of the second elongated hole 522.

[0047] Figure 1The locking element 500 is shown arranged in the interior region 25 of the antenna base 20, such that the actuator 400 is arranged between the branches 510, 520 of the locking element 500. The first pin 410 of the actuator 400 is guided in a first elongated hole 512 of the first branch 510 of the locking element 500. The second pin 420 of the actuator 400 is guided in a second elongated hole 522 of the second branch 520 of the locking element 500. As a result, the locking element 500 is mechanically coupled to the actuator 400, such that translational movement of the actuator 400 about the spindle 300 causes displacement of the locking element 500 in a displacement direction 540 perpendicular to the base plate 100. The latching ends 560 of the branches 510, 520 of the locking element 500, with their latching hooks 511, 521, protrude out of the interior region 25 of the antenna base 20 through the hole 110 in the base plate 100.

[0048] Figure 4 and 5 shows the chronological order from Figure 1 The depicted mounting states are perspective views and in each case partial cross-sectional views of the antenna base 20 during mounting of the antenna base 20 on the mounting hole 41 in the vehicle roof 40. In this case, Figure 4 and 5 Views from different viewing directions are shown.

[0049] After connecting the plug connectors 210, 220 of the antenna base 20 to the cables 50, 52, as shown in FIG. Figure 1 As described, antenna base 20 has been positioned above mounting hole 41 in roof 40, with the underside of base plate 100 facing the outside of roof 40 and hole 110 in base plate 100 positioned above mounting hole 41 in roof 40. In the example shown in the figure, plug connectors 210, 220 of antenna base 20 extend through mounting hole 41 in roof 40. However, this is not absolutely necessary. Mounting hole 41 in roof 40 and hole 110 in base plate 100 of antenna base 20 are sealed from the outside by a peripheral sealing ring 120. However, sealing ring 120 may also be omitted.

[0050] The antenna base 20 has been arranged above the mounting hole 41 in the roof 40 so that the branches 510, 520 of the locking element 500 extend through the mounting hole 41 in the roof 40, and the latch end 560 of the locking element 500 having the latch hooks 511, 521 arranged on the branches 510, 520 is located on the inner side of the roof 40.

[0051] exist Figure 4 and 5In the illustrated embodiment, the antenna base 20 of the roof antenna 10 is still in the pre-installed state. In this case, the actuator 400 is positioned on the spindle 300 so that the first pin 410 of the actuator 400 is arranged in the first elongated hole 512 of the locking element 500 near the second longitudinal end 514, and the second pin 420 of the actuator 400 is arranged in the second elongated hole 522 of the locking element 500 near the second longitudinal end 524. The locking element 500 is in the unstressed state 501, which is described above with reference to FIG. Figure 3 In this unstressed state 501 of the locking element 500, the spacing of the branches 510, 520 at the latching end 560 of the locking element 500 is dimensioned such that the latching end 560 can be guided through the mounting hole 41 in the vehicle roof 40 despite the latching hooks 511, 521 formed at the latching end 560. The spacing of the two latching hooks 511, 521 of the locking element 500 is therefore smaller than the diameter of the mounting hole 41 in the vehicle roof 40.

[0052] The longitudinal direction 330 of the spindle 300 forms a first angle 340 with the longitudinal direction 530 of the elongated holes 512, 522 of the locking element 500. In the example shown, the first angle 340 is less than 90 degrees. Furthermore, the longitudinal direction 330 of the spindle 300 forms a second angle 350 with the displacement direction 540 of the locking element 500. In the example shown in the figures, the second angle 350 is also less than 90 degrees. This orientation of the spindle 300 and the elongated holes 512, 522 of the locking element 500 relative to one another enables the locking element 500 to be moved in the displacement direction 540 by the drive 400.

[0053] If the spindle 300 is Figure 4 and 5 The pre-installed state shown begins to rotate, so that the driver 400 arranged on the spindle 300 moves along the longitudinal direction 330 of the spindle 300. As a result, the pins 410, 420 of the driver 400, which are guided in the elongated holes 512, 522 of the locking element 500, move from the second longitudinal ends 514, 524 of the elongated holes 512, 522 in the direction of the first longitudinal ends 513, 523 of the elongated holes 512, 522 of the locking element 500. In this case, due to the relative orientation of the longitudinal direction 330 of the spindle 300 and the longitudinal directions 530 of the elongated holes 512, 522, the locking element 500 is raised in the displacement direction 540, so that the latching hooks 511, 521 of the locking element 500 are pulled in the direction of the mounting hole 41.

[0054] While the locking element 500 is displaced along the displacement direction 540, the branches 510, 520 of the locking element 500 are elastically spread apart by the actuator 400. In the unstressed state 501 of the locking element 500, a second spacing 532 between the branches 510, 520 of the locking element 500, measured between the second longitudinal ends 514, 524 of the elongated holes 512, 522 of the locking element 500, approximately corresponds to the width of the actuator 400 disposed between the branches 510, 520. In contrast, in the unstressed state 501 of the locking element 500, a first spacing 531 between the branches 510, 520, measured at the first longitudinal ends 513, 523 of the elongated holes 512, 522, is smaller than the width of the actuator 400. If the driver 400 is moved in a translational manner along the main axis 300, so that the pins 410, 420 of the driver 400 in the elongated holes 512, 522 of the locking element 500 are displaced in the direction of the first longitudinal ends 513, 523 from the second longitudinal ends 514, 524, the driver 400 elastically presses the branches 510, 520 of the locking element 500 apart, so that the first spacing 531 of the branches 510, 520 measured between the first longitudinal ends 513, 523 of the elongated holes 512, 522 increases. In this case, the locking element 500 moves from its unstressed state 501 to its open state 502.

[0055] Due to the expansion of the branches 510, 520 of the locking element 500, the spacing between the first latching hook 511 arranged on the first branch 510 and the second latching hook 521 arranged on the second branch 520 also increases. In the fully expanded state 502 of the locking element 500, the branches 510, 520 of the locking element 500 are expanded so that the latching hooks 511, 521 abut against the edge 42 of the mounting hole 41 in the vehicle roof 40.

[0056] The spindle 300 can be rotated about its axis of rotation parallel to its longitudinal direction 330 by means of a suitable tool 60, which is inserted through a hole 610 in the cover 600 of the antenna base 20 into the inner region 25 of the antenna base 20 and engages on the drive contour 360 of the spindle 300. The tool 60 can be a screwdriver, for example, having a drive contour that cooperates with the drive contour 360 of the spindle 300.

[0057] Figure 6 and 7 shows the chronological order along the Figure 4 and 5 The depicted case is a partial cross-sectional perspective view of an antenna base 20 arranged on a mounting hole 41 in a vehicle roof 40. In this case, Figure 6 and 7 Views from different viewing directions are shown.

[0058] exist Figure 6 and 7 In the illustrated case, the actuator 400 has been translated on the spindle 300 to such an extent by rotating the spindle 300 that the pins 410, 420 of the actuator 400 are now arranged in the elongated holes 512, 522 of the locking element 500 close to the first longitudinal ends 513, 523. Due to the translational movement of the actuator 400, the locking element 500 has been displaced in the displacement direction 540 to such an extent that the latching hooks 511, 521 now abut against the edge 42 of the mounting hole 41 on the underside of the vehicle roof 40, thereby securing the antenna base 20 to the vehicle roof 40. At the same time, the branches 510, 520 of the locking element 500 have been opened to such an extent that the two latching hooks 511, 521 of the locking element 500 abut against mutually facing portions of the edge 42 of the mounting hole 41 in the vehicle roof 40.

[0059] exist Figure 6 and 7 In the illustrated mounted state, the antenna base 20 can therefore no longer be removed from the mounting hole 41 in the vehicle roof 40 without previously moving the drive 400 on the spindle 300 such that the pins 410, 420 of the drive 400 are displaced from the first longitudinal ends 513, 523 of the elongated holes 512, 522 of the locking element 500 in the direction of the second longitudinal ends 514, 524.

[0060] Figure 8 A partial, enlarged, cross-sectional view of a hole 610 in the cover 600 of the antenna base 20 of the roof antenna 10 is shown. A socket 700 is disposed in the hole 610 in the cover 600. The socket 700 can be made of metal, for example. The socket 700 is securely inserted into the hole 610 in the cover 600, creating a permanent and tight connection between the socket 700 and the cover 600. To this end, the socket 700 can have a suitable anchoring structure on its outer wall, such as an external hexagonal shape.

[0061] The socket 700 has a continuous hole with an inner wall 710. As a result, the hole 610 in the cover 600 provides access to the inner area 25 of the antenna base 20 even when the socket 700 is arranged in the hole 610. For the above-mentioned rotation of the spindle 300, the tool 60 for this purpose can be inserted through the hole 610 in the cover 600 and inserted into the socket 700 arranged in the hole 610.

[0062] In the example depicted, the inner wall 710 of the socket 700 has a first spline shaft profile 711 . However, the first spline shaft profile 711 may be omitted. Furthermore, the inner wall 710 of the socket 700 has a peripheral first groove 720 .

[0063] The conductive socket 700 is connected in an electrically conductive manner to an associated contact surface of the circuit board 200 via contact springs 730 arranged in the inner region 25 of the antenna base 20 .

[0064] After the antenna base 20 of the roof antenna 10 is secured to the vehicle roof 40, it is advantageous to seal the hole 610 in the cover 600 to prevent dust and moisture from entering the interior area 25 of the antenna base 20. To this end, a plug 800 is arranged in the receptacle 700. The plug 800 comprises a conductive material, such as metal. The plug 800 has a cylindrical basic shape with an outer wall 810. The plug 800 can be pushed from the outside of the antenna base 20 into the receptacle 700 arranged in the hole 610 in the cover 600. Figure 8 The illustration shows the plug 800 only partially pushed into the socket 700 . Figure 9 A schematic cross-sectional side view of the plug 800 fully pushed into the socket 700 is shown.

[0065] exist Figure 8 In the example shown, the plug 800 has a second spline profile 811 on its outer wall 810, which is formed to mate with the first spline profile 711 of the socket 700. Due to the first spline profile 711 and the second spline profile 811, the plug 800, when placed in the socket 700, is prevented from twisting about the longitudinal axis of the socket 700 and the plug 800. However, this anti-twist protection can also be achieved by means other than the first spline profile 711 and the second spline profile 811. In this case, the spline profiles 711 and 811 can be omitted.

[0066] The plug 800 is formed in a closed manner, with the result that the hole 610 in the cover 600 is closed by the plug 800. In order to also achieve a seal between the inner wall 710 of the socket 700 and the outer wall 810 of the plug 800, one or more peripheral O-rings 820 can be provided on the outer wall 810 of the plug 800. In the example shown in the figure, the plug 800 has three coaxially arranged O-rings 820. These O-rings 820 are respectively arranged in grooves extending around the outer wall 810 of the plug 800. However, more or fewer than three O-rings 820 can also be provided. The seal between the plug 800 and the socket 700 can also be achieved in another way.

[0067] The plug 800 has a rod receiving hole 850 with a thread 860 at its outer longitudinal end. The rod receiving hole 850 is used to receive the rod 30 of the roof antenna 10, such as Figure 9 The rod 30 may also be referred to as an antenna rod. The rod 30 has threads 35 that can be screwed into threads 860 of a rod receiving hole 850 in the plug 800.

[0068] The outer wall 810 of the plug 800 has a second groove 830. The second groove 830 is arranged on the outer wall 810 of the plug 800 so that when the plug 800 is fully pushed into the socket 700, the second groove 830 of the plug 800 is concentrically arranged relative to the first groove 720 on the inner wall 710 of the socket 700. The peripheral fixing ring 840 is arranged in the second groove 830 of the plug 800. The second groove 830 has an opening that extends from the outer wall 810 of the plug 800 to the rod receiving hole 850. The protrusion 845 of the fixing ring 840 extends through the opening and into the rod receiving hole 850. This can be Figure 9 Seen in.

[0069] After the plug 800 is arranged in the socket 700 , the rod 30 may be screwed into the plug 800 . Figure 10 An illustration of the hole 610 in the cap 600 is shown with the socket 700 disposed in the hole 610 , the plug 800 with the rod 30 disposed in the socket 700 , and the rod 30 threaded into the rod receiving hole 850 in the plug 800 .

[0070] By screwing the rod 30 into the rod receiving hole 850, the protrusion 845 of the fixing ring 840 that extends into the rod receiving hole 850 is pressed outward from the rod receiving hole 850, thereby elastically deforming the fixing ring 840 so that it now partially protrudes into the first groove 720 of the socket 700, which is arranged concentrically with the second groove 830 of the plug 800. As a result, the plug 800 is fixed in the socket 700 and is secured to prevent it from being accidentally pulled out. Therefore, the plug 800 can no longer be removed from the socket 700 without first unscrewing the rod 30 from the plug 800.

[0071] An electrically conductive connection exists from the rod 30 to the circuit board 200 of the roof antenna 10 via the plug 800 , the socket 700 and the contact spring 730 .

[0072] Figure 11 A schematic perspective view and a partial cross-sectional view of the roof antenna 10 are shown after the roof antenna 10 has been installed in the mounting hole 41 in the vehicle roof 40. To remove the roof antenna 10, the above-described installation steps must be performed in reverse order. Therefore, the rod 30 is first unscrewed. The plug 800 is then removed from the socket 700. The spindle 300 can then be rotated using the tool 60, causing the locking element 500 to shift along the displacement direction 540. This disengages the latching hooks 511, 521 of the locking element 500 from the edge 42 of the mounting hole 41, and the locking element 500 returns from its open position 502 to its unstressed position 501. The antenna base 20 can then be lifted from the mounting hole 41 in the vehicle roof 40.
