BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, an antenna element 1 is fixed in a spoiler housing 2 made of a resin material.
It is connected to an amplifier 3 (not shown) installed inside or outside the spoiler housing 2.
Is located outside the spoiler housing 2 and is connected to a tuner 4 which is a receiving device.

FIG. 2 is a perspective view showing a spoiler with a built-in antenna according to the first embodiment of the present invention. The spoiler housing 2 includes a spoiler portion 2a and two leg portions 2b. On the other hand, the antenna element 1 is composed of a substrate 1a that is compatible with the spoiler housing 2 and is formed of, for example, the same kind of resin material, and an antenna body 1b formed by plating on the substrate 1a. Further, the antenna element 1 is insert-molded in the main body portion 1c fixed by being insert-molded in the spoiler portion 2a of the spoiler housing 2 and in the leg portion 2b of the spoiler housing 2. It is constituted by the connecting portion 1d fixed by the above.

As shown in FIG. 3, a bent portion 1da is formed at the end of the connecting portion 1d, and the mounting bolt 5 as a conductor is inserted together with the leg portion 2b and the vehicle body (not shown). A nut (not shown) is screwed onto the mounting bolt 5 from the vehicle body side so that it is fastened to the rear portion of the vehicle body together with the leg portion 2b.

The mounting bolt 5 is electrically connected to a receiver (not shown) mounted on the vehicle body, or a circuit portion such as an amplifier, and the mounting bolt 5 fixes the spoiler housing 2 to the vehicle body. , The electrical connection of the antenna element 1 is completed at the same time.

A manufacturing process of the spoiler with a built-in antenna according to the present invention will be described. First, the antenna element 1 in which the antenna body 1b is formed on the substrate 1a by plating is placed in the molding die for the lower portion of the spoiler housing 2, and the mounting bolt 5 is placed at the corresponding position.
Then, the resin material in a molten state by heating is injected into a molding die for the lower portion of the spoiler housing 2 to mold the lower portion of the spoiler housing 2. Finally, the upper portion of the spoiler housing 2, which is similarly injection-molded with the molding die for the upper portion of the spoiler housing 2, is joined to the lower portion by welding to complete the spoiler with a built-in antenna.

FIG. 4 is a perspective view showing a spoiler with a built-in antenna according to a second embodiment of the present invention. Book second
The spoiler with built-in antenna according to the first embodiment is the first
The difference from the spoiler with a built-in antenna according to the embodiment is that the antenna element 1 is formed only by the main body portion 1c, and the amplifier 6 is mounted on the antenna element 1. The amplifier 6 is fixed on the substrate 1a of the antenna element 1 by a screw or the like (not shown), and is connected to a connector 6a connected to the antenna body 1b of the antenna element 1 and a receiver (not shown) mounted on the vehicle body. The cable 6b is provided.

As shown in FIG. 5, the connector 6a includes a cable 6aa and a plug 6ab electrically connected to the cable 6aa by caulking the cable 6aa after the cable 6aa is arranged inside. The plug 6ab has a notch 6ac, and the engaging pin 1b is provided in the notch 6ac with respect to the boss 1ba provided on the antenna body 1b.
After b is inserted, it is attached by rotating about the axis.

Alternatively, as shown in FIG. 6, it may be mounted by inserting a plug 6ab having a plurality of slits 6ad at its end into a boss 1ba having no engaging pin 1bb. In this case, the inner diameter of the end portion of the plug 6ab is slightly smaller than the outer diameter of the boss 1ba.

The spoiler with a built-in antenna according to the present invention is
In addition to the antenna element 1 described above, it can be applied to a spoiler incorporating an antenna including a counterpoise connected to the ground side.

[0020]

According to the spoiler with a built-in antenna according to the present invention, it is not necessary to solder when connecting the antenna element and the circuit part such as the amplifier, and the productivity is high. It can be a spoiler.

Further, since a circuit portion such as an amplifier can be arranged inside the spoiler, the space inside the vehicle can be effectively used.
