Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an antenna device for a vehicle, and particularly to an improvement of an antenna device for a truck or the like equipped with a device for connecting a feeder line for an electric device outside the vehicle body, such as a signboard light.

In trucks, taxis, etc., signboard lights displaying the company name, etc. on the cabin roof and other external electrical equipment are often installed, but it is natural that power must be distributed to these electrical equipment from a power source inside the vehicle. Some conventional trucks use an antenna device mounted on the cab roof for this purpose, but when connecting the power cord for the electrical equipment mentioned above to the power source inside the vehicle, first remove the antenna and then First, cut and open the wire inlet prepared in advance in the antenna packing, insert the wire into the opening, fit a grommet into the corresponding hole in the cab roof, draw the wire into the cab from here, and insert the wire into the cab. The procedure involves removing the overhead console or (and) ceiling lining, connecting the chassis side power supply harness indoors, and finally restoring the overhead console or (and) ceiling lining and reinstalling the antenna. Therefore, there are disadvantages in that it requires a lot of effort, increases the working time, and increases the cost of installing the electrical equipment.

The present invention was devised in view of the above, and includes an antenna base that supports an antenna that is removably attached to the outer panel of the vehicle body through elastic packing. A power supply connector, which is to be connected at one end to the on-vehicle power supply and at the other end to a corresponding connector for an electrical device outside the vehicle body, is housed in the space, and the external electrical device is communicated with the elastic packing and the space. The present invention provides a vehicle antenna device characterized by being provided with an introduction section for a feeder line.

Hereinafter, an embodiment in which the present invention is applied to a truck cab will be described in detail with reference to the accompanying drawings. In the figure, the reference numeral 10 generally indicates an antenna base, 12 an antenna rod pivotally supported on the antenna base by a pivot 14, 16 a roof panel of the cab of the truck, and 18 the antenna base 10. This is a packing made of an elastic material such as rubber that is interposed between the roof panel 16 and the roof panel 16. Above antenna base 1
0 is provided with a screw hole 20 into which a mounting screw (not shown) is inserted, and the mounting screw is inserted into a nut fixed to the vehicle interior side of the roof panel 16 through the screw hole 20 and the corresponding through hole 22 of the packing 18. 2
4, the antenna base 10 can be fixed onto the roof panel 16.
Further, the antenna rod 12 is attached to the roof panel 1.
The elastic packing 1 is electrically connected to a feeder line 28 of a radio or the like by a well-known structure via a mounting bracket 26 fixed to the passenger compartment side of the elastic packing 1.
8 is provided with an opening 30 through which the feeder wire 28 passes. On the other hand, a space 32 is provided at the end of the antenna base 10 opposite to the antenna rod 12 side, and the space 32 is connected in advance to an on-vehicle power source (not shown), or is provided with special care for the cab and its internal structure. A power supply connector 34 prepared in advance so that it can be connected at any time as necessary without adding
It also has a sufficient volume to accommodate a connector 36 for an external electrical device that engages with the power supply connector 34. The lower end of the power supply connector 34 passes through the corresponding opening on the roof panel 16 and the through hole 38 on the elastic packing 18, extends into the vehicle interior, is connected to the power supply line 40, and is connected to the power supply line 40 in the vertical direction. A flange 42 having a larger diameter than the opening of the roof panel 16 is provided in the middle portion. This flange 42
Since this is to prevent the power supply connector 34 from passing through the opening of the roof panel 16 and falling into the interior of the vehicle, it can be replaced equally effectively with a suitable fall prevention device such as a clip.
Further, the elastic packing 18 has a protrusion 44 projecting outward and having a small diameter internal hole communicating with the cavity 32, and the tip of the protrusion 44 can be cut off when installing an external electrical device. Accordingly, it is possible to form an introduction part for a power supply line 46 whose one end is connected to the connector 36 and the other end is connected to the electrical equipment. A peripheral wall 48 extending in the vertical direction is surrounded by the outer periphery of the packing 18, and by fitting the peripheral wall 48 into a corresponding fitting groove 50 formed at the lower end of the antenna base 10, It is constructed to ensure watertightness.

In the above structure, when distributing power to a signboard light or other external electrical equipment, loosen the mounting screw and pull it out from the nut 24 to remove the antenna base 10 from the roof panel 16, and then attach the protrusion 44 of the elastic packing 18 with its tip. disconnect. Next, the power supply line 46 is inserted into the internal hole of the protrusion 44, and the connector 36 at the end thereof is connected to the power supply connector 34 prepared in advance in the cavity 32. Fitting groove 5 of antenna base 10
0, insert the mounting screw into the screw hole 20, and screw it into the nut 24. According to this structure, the power supply connector 34 for external electrical equipment is prepared in advance in the empty space 32, so it is possible to eliminate the trouble of removing the cab roof lining, overhead console, etc. and restoring it again as in the conventional case. It has the advantage of being able to be constructed quickly, easily and at low cost.

In addition, in the above structure, the elastic packing 18
and the antenna base 10 (peripheral wall 48
and a fitting groove 50) and an elastic packing 1
The watertight structure between the roof panel 8 and the roof panel 16 can be changed as desired. For example, a watertight lip that abuts against the roof panel 16 can be provided on the outer peripheral edge of the elastic packing 18. Further, the electrical device side connector 36 may be prepared in the empty space 32 by fitting it into the power supply connector 34 in advance. Of course, in this case, the power supply line 46 is usually not wired, but it is also optional to partially insulate it and store it in the space and draw it out to the outside as necessary.

As described above, the vehicle antenna device according to the present invention has an antenna base that supports the antenna detachably attached to the outer panel of the vehicle body through elastic packing, and the antenna device is formed inside the antenna base. A power supply connector, which is to be connected at one end to the in-vehicle power supply and at the other end to a corresponding connector for electrical equipment outside the vehicle body, is housed in the space provided, and at the same time, a power supply connector is stored in the elastic packing, and the power supply connector is connected to the space in the above-mentioned elastic packing. It is characterized by being provided with an introduction part for a power supply line for external electric equipment, and is extremely useful because it has a simple structure and wiring work for external electric equipment can be carried out quickly, easily, and at low cost.
