[Connection between coaxial cable and glass antenna for automobile via power supply terminal]
The catcher 41 is connected to an automotive glass antenna formed on the inner surface of the window glass before the window glass is attached to the automobile. The connection between the catcher 41 and the automobile glass antenna is made by connecting a core wire side contact 431 and a ground side feeding contact 432 provided on the catcher 41 to the core side feeding point 21 and the earth side feeding point 31 of the automobile glass antenna, respectively. It is made by connecting to. The connection is generally made with solder, but can also be made with a conductive adhesive.

  As described above, the core-side power supply point 21 and the ground-side power supply point 31 are arranged vertically apart from each other, and the core-wire-side power supply point 21 is farther from the upper edge 61 on the flange side than the ground-side power supply point 31. When the catcher 41 is connected to the glass antenna for an automobile, the fitting member front end surface 422 of the fitting member 42 is located farther from the flange upper side edge 61 than the fitting member rear end surface 424. And a line segment e connecting the center of the fitting member front end face 422 and the fitting member rear end face 423 is perpendicular to the flange upper side edge 42.

Further, the rear end surface 424 of the fitting member is positioned in a direction facing the flange upper side edge 61. Therefore, the direction which faces the vehicle inner surface side of the fitting member 42 and the flange upper side edge 61 is open.
The connector 44 is attached to the tip of the coaxial line 5 before attaching the window glass to the automobile and before attaching the coaxial line 5 to the receiver. The core wire and the outer conductor at the tip of the coaxial wire 5 are connected to predetermined positions inside the connector 44, respectively. Thus, when the connector 44 is fitted to the fitting portion 421 of the catcher 41, the core wire of the coaxial wire 5 is electrically connected to the core wire-side feeding point 21 of the automotive glass antenna. The outer skin conductor is electrically connected to the ground-side feeding point 31.

The antenna sensitivity of the antenna can reduce the problem that the twisting of the coaxial line changes for each vehicle body. Since the amplifier also electrically connects the outer conductor of the coaxial line 5 to the vehicle body, the same effect as the ground plate can be obtained.

  The connector 44 is fitted into the catcher 41 after the window glass is attached to the automobile.

  When the connector 44 is fitted to the catcher 41, the relative positional relationship of the connector 44 with respect to the catcher 41 is uniquely determined as described above. Therefore, as shown in FIG. 1, when fitting the connector 44 to the catcher 41, the direction of the line segment f connecting the center of the connector front end surface 441 and the center of the connector rear end surface 443 is set to the front end of the fitting member. The direction of the line connecting the center of the surface 422 and the center of the rear end surface 424 of the fitting member is the same, that is, the connector front end surface 441 of the connector 44 is on the side of the fitting member front end surface 422 of the catcher 41. Thus, the connector lower surface 445 of the connector 44 is placed in the same direction as the direction in which the fitting member upper surface 425 of the catcher 41 faces, so that the connector rear end surface 443 is on the side of the fitting member rear end surface 424 of the catcher 41. The connector 44 is fitted to the fitting portion 421 of the catcher 41 in such a manner as to be directed. Here, the line segment f connecting the center of the connector front end surface 441 and the center of the connector rear end surface 443 indicates a projection when the line segment is projected onto the window glass.

  When the connector 44 is fitted to the catcher 41, the fitting member rear end surface 424 of the catcher 41 is opened, so that the coaxial line 5 is caught by the fitting member from the connector rear end portion 443 of the connector 44. Can be prevented.

  When the connector 44 and the fitting portion 421 of the catcher 41 are fitted, the core wire of the coaxial line 5 is electrically connected to the core wire side power supply contact 431, and the outer skin of the coaxial line 5 is connected to the ground side power supply contact. 432 is electrically connected. Such a state is called that the coaxial line 5 and the glass antenna for an automobile are connected via the feeding terminal 4.

[Automobile interior materials]
The coaxial cable 5 and harnesses for connecting in-vehicle products other than the antenna are arranged in the vehicle, and an interior material is attached to the ceiling of the vehicle so as to hide them.
Such an interior material has an edge that reaches a position beyond the flange upper edge 61 and improves the aesthetics so that the boundary between the window glass and the flange upper edge 61 cannot be seen. Yes. And after attaching the said interior material to a ceiling, the said window glass is attached to the motor vehicle.

[Work to connect the connector to the catcher]
When the window glass is attached to an automobile, an automobile glass antenna is disposed in the vicinity of the flange upper edge 61 on the inner side of the automobile, and the connector 44 connected to the front end of the coaxial line 5 includes: It is turned from the upper side of the flange 6 and hangs down in the vicinity of the place where the catcher 41 is attached, which exceeds the edge 61 on the upper side of the flange.

  The operator picks up the connector 44 by hand and fits the connector 44 to the catcher 41. When the connector 44 is fitted to the catcher 41, the positional relationship of the connector 44 with respect to the catcher 41 is uniquely determined as described above, so the front end surface 422 of the fitting member of the catcher 41 on the window glass faces. It is necessary to match the direction of the connector front end surface 441 of the connector 44 in accordance with the direction of the connector 44 and overlap the shape of the connector lower surface 445 so as to overlap the shape of the opening of the fitting member upper surface 425 of the catcher 41.

  In this embodiment, the catcher 41 is attached in the vicinity of the flange upper side edge 61, but the fitting member front end surface 422 is farther from the flange upper side edge 61 than the fitting member rear end surface 424. And a line segment e connecting the center of the fitting member front end surface 422 and the fitting member rear end surface 423 is arranged to be perpendicular to the flange upper side edge 42.

  When the operator tries to pinch the connector 44 by hand to fit the catcher 41, the connector front end surface 441 is positioned farther from the flange upper side edge 61 than the connector rear end surface 443. Thus, the operator can fit the catcher 41 without greatly changing the direction of the connector tip surface 441 of the connector 44. When the connector 44 is fitted to the catcher 41, the connector front end surface 441 exists at a position farther from the flange upper side end edge 61 than the connector rear end surface 443.

  If the direction in which the connector front end surface 441 of the connector 44 faces is largely changed, for example, when the connector front end surface 441 is directed in the direction of the side of the flange 6, it is shown in FIG. Thus, when the connector 44 is pinched with the thumb and index finger of the operator's right hand, depending on the position of the catcher 41, the index finger, middle finger, ring finger, and little finger approach the edge of the interior edge of the flange upper side edge 61. Some fingers may hit the interior.

  In the power supply structure for a glass antenna for an automobile according to the present embodiment, the catcher 41 is positioned farther from the upper edge 61 of the flange upper side where the coaxial line 5 intersects the front end surface 422 of the fitting member than the rear end surface 424 of the fitting member. Therefore, when the operator works with his / her right hand, when the connector 44 is pinched with the thumb and index finger, the direction in which the connector tip surface 441 of the connector 44 faces is the direction in which the fitting member tip surface 422 of the catcher 41 faces. In this case, the index finger, middle finger, ring finger, and little finger of the operator can be prevented from hitting the inner edge of the flange upper edge 61.

  Further, in the glass antenna power feeding structure of the present embodiment, the center of the fitting member front end surface 422 and the center of the catcher rear end surface 424 are connected, and the direction of the line segment e is perpendicular to the flange upper edge 61. Therefore, when the operator engages the connector 44 with the catcher 41, the connector front end surface 441 is positioned farther from the flange upper side edge 61 than the connector rear end surface 443 before the connector 44 is engaged. And the line segment f connecting the center of the connector front end surface 441 and the center of the connector rear end surface 443 of the connector 44 is perpendicular to the flange upper side end edge 61. An operator pinched with the thumb and index finger of the right hand can catch the catcher without changing the direction in which the connector front end surface 441 of the connector 44 is facing. It is possible to fit 41, the work can be performed as reliably operator's hand does not hit the interior covering the flange upper side edge 61.

  Here, when the operator performs the work of pinching the connector 44 and fitting it into the catcher 41, the position of the connector 44 is adjusted by rotating the connector front end surface 441 counterclockwise with respect to the connector rear end surface 443. In this case, it is assumed that the right hand is used and the left hand is used when the position is adjusted by rotating clockwise.

  Assumed in this way, when the connector 44 and the catcher 41 are fitted to each other unless this is done, even if the connector 44 is turned clockwise using, for example, the right hand, no force is applied to the hand, This is because it is difficult to fit the connector 44 to the catcher 41 and the working efficiency is lowered.

  As described above, in the present invention, the operator adjusts the position by rotating the connector 44 counterclockwise using the right hand, or the position adjusted by rotating the connector 44 clockwise using the left hand. By adjusting the position of the connector 44 relative to the catcher 41 in this way, any one of the operator's index finger, middle finger, ring finger, and little finger crosses the coaxial line 5 and is in the vicinity of the glass antenna for an automobile. This prevents the work efficiency from being reduced by hitting the structure of the flange located at or the interior material covering the flange.

  In the present embodiment, the coaxial line is positioned and fixed by the vehicle body on the upper side of the flange 6. When the positioning and fixing position is provided in the vicinity of the edge on the flange upper side, the position is a position in the vicinity of the feeding terminal 4 of the glass antenna for an automobile of the present embodiment. Therefore, the connector 44 can be fitted to the catcher 41 without greatly bending the coaxial line 5 from the position in the power supply structure for the glass antenna for an automobile of the present embodiment.

  In the automobile glass antenna feeding structure as shown in FIG. 2, in order to fit the connector 44 to the catcher 41, it is necessary to largely curve the coaxial line 5. Therefore, when the operator engages the connector 44 with the catcher 41, in addition to the operation of matching the shape of the connector lower surface 445 of the connector 44 with the shape of the opening of the fitting member upper surface 425 of the catcher 41, the coaxial line 5 It was necessary to make the connector 44 stand still against the repulsive force caused by bending of the connector. In the automotive glass antenna of the present embodiment, the repulsive force of the coaxial line 5 is also reduced, so that the working efficiency is improved.

  In the present invention, the distance g between the connector rear end surface 443 and the flange end edge 61 where the coaxial line intersects is more preferably 10 mm to 60 mm. By setting it to 10 mm or more, the operator can more easily perform the operation of fitting the connector 44 to the catcher 41. In addition, by setting the distance to 60 mm or less, the glass antenna for an automobile having a power feeding structure for the glass antenna for an automobile according to the present invention is arranged at a position close to the flange edge so that it is difficult for the driver to enter the field of view. can do.

[Connection between coaxial cable and glass antenna for automobile via power supply terminal]
The catcher 41 is connected to an automotive glass antenna formed on the inner surface of the window glass before the window glass is attached to the automobile. The connection between the catcher 41 and the automobile glass antenna is made by connecting a core wire side contact 431 and a ground side feeding contact 432 provided on the catcher 41 to the core side feeding point 21 and the earth side feeding point 31 of the automobile glass antenna, respectively. It is made by connecting to. The connection is generally made with solder, but can also be made with a conductive adhesive.

  As described above, the two ground-side feeding points 31 are arranged in the vicinity of the flange upper side edge 61 so as to be separated from each other in the vertical direction with respect to the flange upper side edge 61. Further, the core wire side feeding point 21 is disposed between the two ground side feeding points 31.

  The catcher 41 connects the two ground side power supply contacts 432 to each of the two ground side power supply points 31 so that the fitting member rear end surface 424 of the fitting member 42 faces the upper edge 61 of the flange, and the core wire The side power supply contact 431 is connected to the core wire side power supply point 21.

  The catcher 41 is connected to the automobile glass antenna so that the fitting member upper surface 425 of the fitting member 42 faces the vehicle inner surface side of the window glass. Further, the rear end surface 424 of the fitting member is positioned in a direction facing the flange upper side edge 61. Therefore, the direction which faces the vehicle inner surface side of the fitting member 42 and the flange upper side edge 61 is open.

  The connector 44 is attached to the tip of the coaxial line 5 before attaching the window glass to the automobile and before attaching the coaxial line 5 to the receiver. Since the connection method between the connector 44 and the coaxial line 5 is the same as that in the first embodiment, it is omitted here.

  The coaxial line 5 having the connector 44 connected to the tip of the connector circulates the interior of the automobile from the receiver side so that the connector 44 is disposed on the upper side of the flange 6 before the window glass is attached to the automobile. It is. At this time, the connector 44 is hung from the upper side of the flange 6 to the vehicle inner side near the opening 61 of the automobile to which the window glass is attached, beyond the flange upper side edge 61. Thereafter, before the window glass is attached, the interior material is attached to the ceiling inside the vehicle.

The coaxial line 5 may directly connect the connector 44 and the receiver, but an amplifier or a ground plate may be provided between the connector 44 and the receiver.
The connector 44 is fitted into the catcher 41 after the window glass is attached to the automobile.

  When the connector 44 is fitted to the catcher 41, the relative positional relationship of the connector 44 with respect to the catcher 41 is uniquely determined in the same manner as the power supply terminal 4 used in the glass antenna for an automobile of the first embodiment. Therefore, when the connector 44 is fitted to the catcher 41, the connector front end surface 441 of the connector 44 is located on the side of the fitting member front end surface 422 of the catcher 41 as shown in FIG. The rear end surface 443 is on the side of the fitting member rear end surface 424 of the catcher 41, and the connector upper surface 443 of the connector 44 is directed in the same direction as the direction of the fitting member upper surface 425 of the catcher 41.

[Automobile interior materials]
Since the interior material of the automobile has been described in the description of the first embodiment, it is omitted here.

[Work to connect the connector to the catcher]
Immediately after the window glass is attached to the automobile, the arrangement of the catcher 41 and the connector 44 inside the automobile is the same as that of the first embodiment.

  That is, the catcher 41 is attached in the vicinity of the flange upper side edge 61, and the fitting member front end surface 422 is disposed at a position farther from the flange upper side edge 61 than the fitting member rear end surface 424. In addition, a line segment e connecting the center of the fitting member front end face 422 and the fitting member rear end face 423 is arranged to be perpendicular to the flange upper side edge 61.

  The connector 44 is connected to the tip of the coaxial line 5 extending from the receiver. Since the coaxial line 5 hangs from the upper side of the flange 6 so as to intersect with the flange upper side edge 61, the connector 44 faces the connector rear end surface 443 toward the flange upper side edge 61. It will be hanging on. The connector front end surface 441 is farther from the flange upper side edge 61 than the connector rear end surface 443, and the line segment f connecting the center of the connector front end surface 441 and the center of the connector rear end surface 443 is a flange. It is substantially perpendicular to the upper side edge 61.

  In the power supply structure for a glass antenna for an automobile according to this embodiment, the catcher 41 and the connector 44 are arranged so as to have the same arrangement as in the first embodiment, so that the operator pinches the connector 44 by hand. Thus, when performing the operation of fitting the catcher 41, the operation can be performed efficiently without the hand touching the interior material.

  In the present embodiment, as in the first embodiment, the line segment e connecting the center of the fitting member front end surface 422 and the center of the fitting member rear end surface 424 of the catcher 41 is the coaxial line 5 to which the connector 44 is connected. Although it is perpendicular to the intersecting flange upper edge 61, it is not always necessary to do so as in the first embodiment.

  That is, if the fitting member front end surface 422 of the catcher 41 is located farther from the flange upper side end edge 61 where the coaxial line 5 intersects than the fitting member rear end surface 424, the operator holds the connector 44 by hand. When the operation of fitting the connector 44 to the catcher 41 by pinching is performed, the connector front end surface 422 of the connector 44 is rotated with respect to the connector rear end surface 424. When the connector front end surface 422 of the connector 44 is aligned with the fitting member front end surface 422 of the catcher 41 and the connector front end surface 422 is rotated with respect to the connector rear end surface 424, the connector front end surface 422 of the connector 44 is It is always at a position farther from the flange upper edge 61 where the coaxial line 5 intersects 424.

  Therefore, an angle formed by a line segment e connecting the center of the fitting member front end surface 422 and the center of the fitting member rear end surface 424 of the catcher 41 and a perpendicular to the flange upper side edge 61 where the coaxial line 5 intersects. If the operator's hand for fitting the connector 44 to the catcher 41 does not hit the interior material, the direction of the line segment f connecting the center of the connector front end surface 441 and the center of the connector rear end surface 443 is determined. Since the direction of the line segment e connecting the center of the front end surface 422 of the fitting member and the center of the rear end surface 424 of the fitting member is matched, the operator can pinch the connector 44 by hand to fit the catcher 41. Can be performed efficiently.

  Further, as in the case of the power supply structure for the glass antenna for an automobile according to the first embodiment, it is not necessary to bend the coaxial line 5 greatly. Therefore, prior to fitting the connector 44 to the catcher 41 by the operator, the coaxial line 5 Since it is not necessary to adjust the position of the connector 44 and the catcher 41 while resisting the repulsive force, the working efficiency is improved.

  In the present invention, the distance g between the connector rear end surface 443 and the flange end edge 61 where the coaxial line intersects is more preferably 10 mm to 60 mm. By setting it to 10 mm or more, the operator can more easily perform the operation of fitting the connector 44 to the catcher 41. In addition, by setting the distance to 60 mm or less, the glass antenna for an automobile having a power feeding structure for the glass antenna for an automobile according to the present invention is arranged at a position close to the flange edge so that it is difficult for the driver to enter the field of view. can do.

At this time, the connector 44 is hung from the upper side of the flange 6 to the vehicle inner side near the opening 61 of the automobile to which the window glass is attached, beyond the flange upper side edge 61. Thereafter, before the window glass is attached, the interior material is attached to the ceiling inside the vehicle.

  The coaxial line 5 may directly connect the connector 44 and the receiver, but an amplifier or a ground plate may be provided between the connector 44 and the receiver.

  The connector 44 is fitted into the catcher 41 after the window glass is attached to the automobile. When the connector 44 is fitted to the catcher 41, the relative positional relationship of the connector 44 with respect to the catcher 41 is uniquely determined in the same manner as the power supply terminal 4 used in the glass antenna for an automobile of the first embodiment. Therefore, when fitting the connector 44 to the catcher 41, as shown in FIG. 5, the connector front end surface 44 of the connector 44 and the fitting member rear end surface 424 of the fitting member 42 are opposed to each other. The fitting is performed after adjusting so that the shapes match.

  When the connector 44 is fitted to the catcher 41, the fitting member rear end surface 424 of the catcher 41 is opened, so that the coaxial line 5 is caught by the fitting member from the connector rear end portion 443 of the connector 44. Can be prevented.

[Automobile interior materials]
Since the interior material of the automobile has been described in the description of the first embodiment, it is omitted here.

[Work to connect the connector to the catcher]
Immediately after the window glass is attached to the automobile, the arrangement of the catcher 41 and the connector 44 inside the automobile is the same as that of the first embodiment. That is, the catcher 41 is attached in the vicinity of the flange upper side edge 61, and the fitting member front end surface 422 is disposed at a position farther from the flange upper side edge 61 than the fitting member rear end surface 424. In addition, a line segment e connecting the center of the fitting member front end face 422 and the fitting member rear end face 423 is arranged to be perpendicular to the flange upper side edge 61.

  Moreover, the connector 44 is connected to the front-end | tip part of the coaxial line 5 extended | stretched from the said receiver. The coaxial line 5 is positioned and fixed on the vehicle body on the flange upper side by a clip, an amplifier, or a ground plate. Since the coaxial line 5 hangs from the upper side of the flange 6 so as to intersect with the flange upper side edge 61, the connector 44 faces the connector rear end surface 443 toward the flange upper side edge 61. It will be hanging on. That is, the connector front end surface 441 is located farther from the flange upper side edge 61 than the connector rear end surface 442.

  In the power supply structure for a glass antenna for an automobile according to this embodiment, the catcher 41 and the connector 44 are arranged so as to have the same arrangement as in the first embodiment, so that the operator pinches the connector 44 by hand. Thus, when performing the operation of fitting the catcher 41, the operation can be performed efficiently without the hand touching the interior material.

  In the present embodiment, as in the first embodiment, the line segment e connecting the center of the fitting member front end surface 422 and the center of the fitting member rear end surface 424 of the catcher 41 is the coaxial line 5 to which the connector 44 is connected. Although it is perpendicular to the intersecting flange upper edge 61, it is not always necessary to do so as in the first and second embodiments.

  In the present invention, the distance g between the connector rear end surface 443 and the flange end edge 61 where the coaxial line intersects is more preferably 10 mm to 60 mm. By setting it to 10 mm or more, the operator can more easily perform the operation of fitting the connector 44 to the catcher 41. In addition, by setting the distance to 60 mm or less, the glass antenna for an automobile having a power feeding structure for the glass antenna for an automobile according to the present invention is arranged at a position close to the flange edge so that it is difficult for the driver to enter the field of view. can do.

<Embodiment 4>
[Configuration of Glass Antenna for Automobile of this Embodiment and its Feeding Structure]
The glass antenna for an automobile and the power feeding structure thereof according to the present invention can have a configuration as in Embodiment 4 shown in FIG. 9, for example. FIG. 9 is a view of a state in which the glass antenna for an automobile according to the fourth embodiment is attached in the vicinity of the flange side edge 61 of the automobile flange 6 of the automobile windshield as viewed from the vehicle interior side.

The glass antenna for an automobile according to the fourth embodiment is different from the glass antenna for an automobile according to the first embodiment in the direction in which the feeding terminal 4 is attached and the edge of the flange 6 where the coaxial line 5 intersects. The configurations of the element 22 and the ground side element 32 are different. In addition, in the glass antenna for motor vehicles of this embodiment, since the same power supply terminal 4 as the power supply terminal 4 used with the glass antenna for motor vehicles of Embodiment 1 is used, here, the structure of the power supply terminal 4 and for motor vehicles are used. Description of the connection method with the glass antenna is omitted.
In the glass antenna for an automobile according to the present embodiment, the ground-side feeding point disposed in the vicinity of the flange side edge 62 in the direction perpendicular to the flange side edge 62 constituting the side of the flange 6. The core-side power feeding point 21 is arranged farther away than 31. That is, as shown in FIG. 9, the flange side edge 62 is substantially vertical, and therefore the direction in which the core wire side feeding point 21 and the ground side feeding point 31 are arranged is a horizontal direction.

  The core wire side element 22 includes a core wire side first wire 221 that is a horizontal wire. One end of the core wire side first strip 221 is connected to the core wire side feeding point 21 and is extended to the right side, that is, in the direction of the left and right center lines of the window glass on which the glass antenna for an automobile of the present embodiment is disposed. Yes. The ground side element 32 includes a ground side first wire 321 that is a vertical wire. One end of the ground-side first wire 321 is connected to the ground-side feeding point 31 and is extended downward.

  The catcher 41 of the power supply terminal 4 connects the core wire side power supply contact 431 and the ground side power supply contact 432 provided in the fitting member 42 to the core wire side power supply point 21 and the ground side power supply point 31, respectively.

Therefore, the fitting portion 42 of the catcher 41 is disposed so that the fitting portion rear end face 424 faces the flange side edge 62.
The connector 44 is connected to the coaxial line 5 extending from a receiver (not shown). The coaxial line 5 is routed from the receiver through the inside of the vehicle, and intersects the flange side edge 62 when the connector 44 is fitted to the catcher 41. The connector 44 is fitted into the catcher 41, and the coaxial line 5 and the automobile glass antenna are electrically connected via the power feeding terminal 4.

[Automobile interior materials]
On the side of the flange 6, that is, on the pillar, the interior material is attached after the connector 44 is fitted to the catcher 41.

[Work to connect the connector to the catcher]
Immediately after the window glass is attached to the automobile, the catcher is provided in the vicinity of the flange side edge 62 on the inner side of the automobile, and the fitting member 42 of the catcher 41 is connected to the flange side edge. The fitting member front end surface 422 is disposed farther than the fitting member rear end surface 424 with respect to the edge 62, and connects the center of the fitting member front end surface 422 and the center of the fitting member 424. The line segment e is disposed so as to be perpendicular to the flange side edge 62.

  The connector 44 is connected to a front end portion of the coaxial line 5 fixed to the vehicle body near the flange side edge 62 by a clip, an amplifier, or a ground plate, and is connected to the clip, the amplifier, or the ground plate. It is in a hanging state. That is, the direction of the line segment f connecting the center of the connector front end surface 441 and the center of the connector rear end surface 443 is a direction along the flange side edge 62.

  When the operator pinches the connector 44 by hand and fits it to the catcher 41, first, the connector 44 is turned counterclockwise around the amplifier or the ground plate, and the center of the connector front end surface 441 and the connector rear end surface are turned. The direction of the line segment f connecting the center of 443 is aligned with the direction of the line segment e connecting the center of the front end face 422 of the fitting member and the center of the rear end face 424 of the fitting member. The connector 44 is fitted to the catcher 41 so that the shape of the connector lower surface 445 of the connector 44 overlaps the shape of the opening of the member upper surface 425.

  The fitting member 42 of the catcher 41 has a fitting member front end surface 441 disposed at a position farther than the fitting member rear end surface 443 with respect to the flange side edge 62, and the fitting member front end. Since the line segment e connecting the center of the surface 441 and the center of the fitting member 442 is disposed so as to be perpendicular to the flange side edge 62, the operator's hand is placed on the coaxial line 5. Therefore, the connector 44 can be efficiently connected to the catcher 41 because it does not overlap with the flange side edge 62 that intersects with each other.

  The connector 44 hangs from the amplifier or the ground plate as described above before being fitted to the catcher 41. For this reason, when such a connector is pinched, the operator's hand may hit the side of the flange 6. However, the operation of pinching the connector 44 is an operation of fitting the connector 44 to the catcher 41, that is, fitting after the connector lower surface 445 of the connector 44 is overlapped with the opening of the fitting member upper surface 425 of the fitting member 42 of the catcher 41. Compared to the work to be combined, a delicate movement is not necessary, so the work efficiency is not lowered.

Like the power feeding structure for the glass antenna for automobiles of this embodiment, the coaxial line 5 to which the connector 44 is connected intersects the flange side edge 62 and feed terminal to the flange side edge 62. When the connector 44 and the catcher 41 are fitted to each other, the connector front end surface 441 is connected to the rear end surface 422 of the connector. By making the position farther from the flange side edge 62 than the end face 443, the operator can fit the connector 44 to the catcher 41 as in the case of the glass antenna for automobiles of the first to third embodiments. Can be implemented efficiently.
The automotive glass antenna power feeding structure of the present embodiment is disposed close to the flange upper edge 61. In such a case, when the worker tries to fit the connector 44 to the catcher 41, the hand holding the worker's connector 44 may hit the flange upper side edge 61.

  Even in such a case, when the operator fits the connector 44 to the catcher 41, it is positioned and fixed by the clip, the amplifier, and the ground plate when the connector 44 is fitted to the catcher 41. The angle between the line segment connecting the center of the fitting member front end surface 422 and the line segment connecting the center of the fitting member rear end surface 424 becomes smaller. Therefore, when the operation of fitting the connector 44 to the catcher 41 is performed, it is not necessary to largely bend the coaxial line 5 from the position where the coaxial line 5 is positioned and fixed.

  Therefore, in the power supply structure for the glass antenna for automobiles of the present embodiment, the operator fits the connector 44 to the catcher 44 without worrying about the repulsive force of the coaxial line 5 generated by bending the coaxial line 5 greatly. Therefore, a reduction in work efficiency can be suppressed.

  In the present invention, the distance g between the connector rear end surface 443 and the flange end edge 61 where the coaxial line intersects is more preferably 10 mm to 60 mm. By setting it to 10 mm or more, the operator can more easily perform the operation of fitting the connector 44 to the catcher 41. In addition, by setting the distance to 60 mm or less, the glass antenna for an automobile having a power feeding structure for the glass antenna for an automobile according to the present invention is arranged at a position close to the flange edge so that it is difficult for the driver to enter the field of view. can do.

  The connector 44 is connected to the coaxial line 5 extending from a receiver (not shown). The coaxial line 5 is routed from the receiver through the vehicle interior, and intersects the flange upper side edge 61 when the connector 44 is fitted to the catcher 41. The connector 44 is fitted into the catcher 41, and the coaxial line 5 and the automobile glass antenna are electrically connected via the power feeding terminal 4.

Since the arrangement with respect to the side edge 61, the arrangement of the core wire side feeding end 21 and the ground side feeding point 31 are the same as those of the glass antenna for an automobile of the first embodiment, the structure of the feeding terminal 4 and the connection with the glass antenna for an automobile here. Description of the method and the manner in which the operator engages the connector 44 with the catcher 41 will be omitted.

  In the automotive glass antenna of the present embodiment, the core wire side element 22 includes a core wire side first wire 221 and a core wire side second wire 222. The core-wire-side first wire 221 is a horizontal wire that is connected to the core-wire-side feeding point 21 and extends horizontally to the right. The core-wire-side second wire 222 is connected to the core-wire-side feeding point 21 and has a lead-out portion which is a horizontal wire extending to the left side, a vertical wire extending vertically upward from the left end of the lead-out portion, and the vertical line It is composed of a horizontal wire connected to the upper end of the strip and extending to the left. In this way, the core wire side element 22 extends the core wire side first wire 221 and the core wire side second wire 222 in the opposite direction to the right side and the left side with respect to the core wire side feeding point 21, respectively.

  The ground side element 32 is composed of a ground side first wire 321. The ground-side first wire 321 is composed of a vertical wire connected to the ground-side feeding point 31 and extended upward, and a horizontal wire connected to the upper end of the vertical wire and extended to the left. The horizontal filament is extended so as to be close along the flange upper side edge 61, and is capacitively coupled with the flange upper side edge 61 within a range surrounded by a dotted line a. A capacitive coupling portion 321a is formed.

Further, as shown by the portion surrounded by the dotted line b, the core side second wire 222 is a part of the ground side feeding point 31, the vertical wire of the ground side first wire 321 and a part of the horizontal wire. Are arranged so as to be close to each other in parallel and are capacitively coupled to a part of the ground-side feeding point 31 and the first ground-side first wire 321 to constitute a capacitive coupling part 222a with the ground-side conductor part. Yes. Further, a part of the ground side feeding point 31 and a part of the ground side first wire 321 that is capacitively coupled with the core wire side second wire 222 forms a capacitive coupling part 321b with the core wire side conductor 2. Yes.
By extending the core wire side first wire 221 and the core wire side second wire 222 constituting the core wire side element 22 in opposite directions with the core wire side feeding point 21 interposed therebetween, like the glass antenna for an automobile of the present embodiment. This makes it easier to adjust the antenna sensitivity of the glass antenna for automobiles of this embodiment.

  For example, when the length of the core wire side first wire 221 and the extending direction are fixed in a certain direction, and the length of the core wire side second wire 222 is adjusted to obtain the optimum sensitivity, When the two wire 222 is extended from the middle part of the core-wire-side first wire 221, the first wire-side first when the radio wave is received by changing the length of the core-wire-side second wire 221. The state of the wave of the radio wave induced on the wire 221 changes, and the same state as when the length of the core wire side first wire 221 is fixed cannot be maintained. Moreover, when extending the core wire side second wire 222 in the same direction as the core wire side first wire 221, the length of the core wire side first wire 221 is fixed and the core wire side second wire 222 is fixed. If the length is changed, the state of the electric field around the core-side first wire 221 when radio waves are received changes greatly. In this case, the length of the core-wire-side first wire 221 is the same as when the length is fixed. I can't keep up. Therefore, if the core-wire-side second wire 222 is connected to the core-wire-side first wire, or is extended in the same direction as the core-wire-side first wire, the core-wire-side first wire 221 and the core-wire-side second wire 222 If the antenna sensitivity is adjusted by changing the length, the adjustment may be difficult.

On the other hand, like the glass antenna for automobiles of the present embodiment, the core wire side first wire 221 and the core wire side second wire 222 are arranged so as to extend to the opposite side across the core wire side feeding point 21. In this case, the above-described influence due to the change in the length of either one is less likely to affect the other, so that it is easier to adjust the antenna sensitivity.
Moreover, in the glass antenna for automobiles of this embodiment, since a part of the ground side first wire 321 forms the capacitive coupling portion 321a of the flange, the ground can be stabilized, and the coaxial wire 5 Even if the scooping from the receiver (not shown) to the glass antenna for an automobile of the present embodiment is different for each automobile, the difference in antenna sensitivity for each automobile can be reduced.

  Furthermore, in the glass antenna for an automobile of the present embodiment, the core-wire-side second wire 222, the ground-side feeding point 31, and a part of the ground-side first wire 321 are close to each other and capacitively coupled. Therefore, the input impedance of the glass antenna for automobiles of this embodiment can be adjusted.

Compared with the case where the portion 321a is formed, the ground can be stabilized, and even if the winding of the coaxial line 5 from the receiver (not shown) to the glass antenna for an automobile of the present embodiment is different for each automobile, It is possible to reduce the difference in antenna sensitivity due to each.

  The core-wire-side second filament 222 is adjacent to and parallel to a part of the vertical portion of the ground-side feeding point 31 and the ground-side first filament 321 as indicated by a portion surrounded by a dotted line b.

<Power Supply Terminal Targeted for Power Supply Structure of Glass Antenna for Car of the Present Invention>
The power supply terminal 4 targeted by the power supply structure of the glass antenna for an automobile of the present invention is the power supply terminal 4 as used in the first to third embodiments. A characteristic of these power supply terminals 4 is that when the connector 41 is fitted to the fitting member 42 of the catcher 41, the relative positional relationship of the connector 41 with respect to the fitting member 42 is uniquely determined. That is, in the power supply terminal 4 used in the first and second embodiments, the shape of the connector lower surface 445 of the connector 44 is not matched with the shape of the opening of the fitting member upper surface 425 of the fitting member 42. In the power supply terminal 4 that cannot be fitted and used in the third embodiment, the shape of the front end surface 441 of the connector 44 is matched with the shape of the opening of the fitting member rear end surface 424 of the fitting member 42. It is necessary to fit with.

  In the fitting portion 421 of the catcher 41, a conductive member is provided for electrically connecting the core wire and the outer conductor of the coaxial line 5 connected to the connector 44 to the core wire side power supply contact and the ground side power supply contact. Therefore, the power feeding terminal 4 targeted by the glass antenna for an automobile of the present invention is aligned as described above, and the coaxial cable is connected via the conductive member by fitting the connector 44 and the catcher 41 together. 5 core wires and outer conductors can be connected to the core wire side power supply contact 431 and the ground side power supply contact 432, respectively.

  Further, as in the case of the power supply structure for the glass antenna for an automobile according to the first embodiment, it is not necessary to bend the coaxial line 5 greatly. Therefore, prior to fitting the connector 44 to the catcher 41 by the operator, the coaxial line 5 Since it is not necessary to adjust the position of the connector 44 and the catcher 41 while resisting the repulsive force, the working efficiency is improved.

<Arrangement of Glass Antenna for Car of the Present Invention on Window Glass>
The glass antenna for automobiles of the present invention is provided on the upper side of the flange 6 as shown in the first to twelfth embodiments. This is because the glass antenna for automobiles of the present invention can obtain high antenna sensitivity when placed at a position as high as possible from the ground.
In particular, as in the examples described later, the automotive glass antenna of the present invention is particularly effective when disposed near the center of the window glass on the upper side of the flange 6. That is, in such a case, the coaxial line 5 sent from the receiver is connected to the automotive glass antenna of the present invention from the upper side of the flange 6.

  Such an effect also applies when the automotive glass antenna of the present invention is disposed on the side of the flange 6. In this case, the coaxial line 5 is connected to the glass antenna for an automobile of the present invention from the side of the flange 6.

  Although the glass antenna for automobiles of the present invention is preferably placed on the upper side of the flange 6 in order to obtain high antenna sensitivity, it is not always necessary to do so. The design requirements of the automobile and the required antenna sensitivity are not necessarily required. It is better to consider the arrangement as appropriate.

<Window glass provided with glass antenna for automobile of the present invention>
The glass antenna for automobiles of the present invention can be attached to a windshield, rear glass, and side glass of an automobile. However, the automotive glass antenna of the present invention is particularly effective when it is attached to the upper side of the windshield.

  The upper side of the Freon glass is covered with the interior material up to the edge of the flange 6 before the window glass is attached. Therefore, when performing the operation of fitting the connector 44 to the catcher 41 connected to the glass antenna provided on the upper side of the window glass, the operator's hand hits the interior material, and the work efficiency is reduced. There were often.

In addition, what is described as “line” here is usually about 0.5 mm to 0.7 mm as a line width, but may be thicker or thinner than that.

<Feeding point and element shape of glass antenna for automobile of the present invention>
The core-side feeding point 21 and the ground-side feeding point 31 used in the glass antenna for automobiles of the present invention are often rectangular. This is because such a shape makes it easier to clearly determine the attachment position of the catcher than, for example, a circular shape.
Further, the areas of the core wire side feeding point 21 and the ground side feeding point 31 are made larger than the areas of the core line side feeding contact 431 and the ground side feeding contact 432 of the catcher 41, respectively, so that the catcher can be physically and stably maintained. 41 can be attached to the glass antenna for automobiles of the present invention.

  In the automotive glass antenna of the present invention, as the core wire side element 22 and the ground side element 32, only the form that is a line was introduced in the description of the embodiment, but it is not necessarily a line, and it is not necessarily a planar shape. It may be a conductor.

The 1-wire 221 is a direction away from the core wire-side feeding point 21 of the other glass antenna for an automobile of the present invention, that is, the left side in the case of the glass antenna 1a for the present invention, and the glass antenna 1b for an automobile of the present invention. If present, it is preferably stretched to the right. By doing in this way, it can suppress that the glass-mounted antenna for motor vehicles of this invention interferes mutually and falls antenna sensitivity.

  The automotive glass antenna of the present invention can obtain a diversity effect even with two, but a further excellent diversity effect can be obtained by attaching the automotive glass antenna to the automobile.

  Although the glass antenna for automobiles to be added can be placed on the side glass or the rear glass, it may be located on the windshield at a position away from the automobile glass antennas 1a and 1b of the present invention.

  Further, when performing diversity reception, it is not necessary to use all the glass antennas for automobiles as the glass antennas of the present invention, and some of them may be the glass antennas for automobiles of the present invention.

<Frequency band in which use of glass antenna for automobile of the present invention is preferred>
In the glass antenna for automobiles of the present invention, the fitting member front end surface 424 is obtained farther away from the fitting member rear end surface 424 of the catcher 41 with respect to the edge of the flange 6 where the coaxial lines extending from the receiver intersect. The effect of improving workability that is applied applies to all the glass antennas for automobiles that use the feeding terminal 4 that is the object of the glass antenna for automobiles of the present invention.

  However, preferred frequency bands for using the glass antenna for automobiles of the present invention are the VHF band and the UHF band. For example, good performance is exhibited in digital terrestrial television broadcasting waves (470 MHz to 770 MHz in Japan) and band 3 bands (174 MHz to 240 MHz) of terrestrial digital radio broadcasting.

<Effect of Glass Antenna for Automobile of the Present Invention and its Power Supply Structure>
According to the power feeding structure of the glass antenna for automobiles of the present invention, the catcher 41 of the power feeding terminal 4 connected to the glass antenna for automobiles of the present invention with respect to the edge of the flange 6 where the coaxial line 5 extending from the receiver intersects. Is attached so that the fitting member front end surface 422 is further away from the fitting member rear end surface 424, so that the operator can connect the connector front end surface 441 of the connector 44 attached to the front end of the coaxial line 5 to the connector rear end surface 443. By fitting the catcher 41 so that the end of the flange 6 intersecting the coaxial line 5 is farther than the connector rear end face 443, the connector without greatly bending the coaxial line 5 Since 44 can be fitted to the catcher 41, the working efficiency when fitting is improved. Further, since the operator's hand can be prevented from hitting the vicinity of the edge of the flange 6 where the coaxial line 5 intersects, when the flange 6 where the coaxial line 5 intersects is on the upper side, the ceiling If the flange 6 intersecting the coaxial line 5 is on another side, the worker's hand should not touch the structure of the car body. The working efficiency for fitting the connector 44 to the catcher 41 can be improved.

  In the power supply structure for a glass antenna for an automobile of the present invention, when the power supply terminal 4 as shown in the first embodiment and the fourth to twelfth embodiments, that is, the connector 44 is fitted to the catcher 41, the connector It is preferable to use a power supply terminal 4 in which the core wire side power supply contact 431 of the catcher 41 is provided before the connector front end surface 441 of the connector 44 and the ground side power supply contact 432 is provided after the connector rear end surface 443. it can. Such a power supply terminal 4 is a common power supply terminal 4 connected to a glass antenna for an automobile having a core-side power supply point 21 and a ground-side power supply point 31 on a window glass. Even if it uses, since the effect which improves an operator's working efficiency as mentioned above is acquired, the need to use a special thing as the electric power feeding terminal 4 can be eliminated.

  In the automotive glass antenna feeding structure of the present invention, the coaxial line 5 extending from the receiver intersects the line f connecting the center of the connector front end surface 441 and the center of the connector rear end surface 443 of the connector 44. By mounting the catcher 41 on the window glass so as to be perpendicular to the edge of the flange 6, the operator can more reliably perform the operation of fitting the connector 44 to the catcher 41. It is possible to prevent the coaxial line 5 extending from the receiver from hitting the intersecting flange 6.

  In the automotive glass antenna feeding structure of the present invention, the distance g between the connector rear end surface 443 and the flange end edge 61 where the coaxial line 6 intersects is more preferably 10 mm to 60 mm. By setting it to 10 mm or more, the operator can more easily perform the operation of fitting the connector 44 to the catcher 41. In addition, by setting the distance to 60 mm or less, the glass antenna for an automobile having a power feeding structure for the glass antenna for an automobile according to the present invention is arranged at a position close to the flange edge so that it is difficult for the driver to enter the field of view. can do.

  The glass antenna for automobiles of the present invention can stabilize the ground by capacitively coupling a part of the ground side conductor portion 3 including the ground side feeding point 31 and the ground side element 32 close to the flange 6. Even if the scooping from the receiver of the coaxial line 5 to the glass antenna for an automobile of the present invention is different for each automobile, the difference in antenna sensitivity for each automobile can be reduced.

The glass antenna for an automobile of the present invention is obtained by capacitively coupling a part of the core wire side conductor portion 2 composed of the core wire side feeding point 21 and the core wire side element 22 close to a part of the ground side conductor portion 3. The input impedance of the automobile glass antenna can be adjusted.
