Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a mounting jig for an in-vehicle antenna that is mounted through the front pillar of an automobile.

2. Description of the Related Art The general installation of a conventional vehicle-mounted antenna will be explained with reference to FIG. That is, the antenna element 1, which is a single rod type or a multi-stage telescopic type, is slidably inserted into the guide tube 3 with at least its top end 1a protruding from the mounting base 2, and is connected to the power feeding part 4. The power supply cable 6, which has a plug 5 connected to the radio set main body at its free end, and the guide tube 3 are connected to the front pillar portion 8 through a hole 7a opened in the roof 7 of the automobile.
The mounting base 2 is supported and fixed to the roof 7. Then, insert the guide tube 3 and the power supply cable 6 into the cavity of the pillar portion 8 at the arrow 9.
When inserting from the direction, the guide tube 3
It is made of synthetic resin and has a long and large diameter, but is flexible, so it is compatible with the curved state of the cavity. (above), and is flexible, so it is easy to deform and get the tip 5a of the plug 5 caught or caught in the mating parts of the steel plates that make up the car body in the cavity, and the power supply cable 6 can be inserted smoothly into the cavity. There were times when I couldn't insert it. Therefore, the wire 10 or the like is connected to the plug 5, and the wire 10 is first inserted into the cavity of the pillar part 8, and the wire 10 is connected to the plug 5.
A method is used in which the power supply cable 6 is inserted into the cavity together with the guide tube 3 by pulling it out in the direction of the arrow 9a. However, the method described above has the drawback that attaching and detaching the wire 10 to and from the plug 5 is troublesome and requires a long time to attach the antenna. Therefore, the applicant of the present invention previously proposed an antenna device shown in FIG. This antenna device is shown in Fig. 7, in which parts corresponding to those in Fig.
As shown in the figure, the tip 5a of the plug 5 is elastically held at the lower end of the guide tube 3 in a removable manner.
The plug 5 and the guide tube 3 are temporarily fixed together by wrapping an adhesive tape 11 such as vinyl tape around their outer peripheries, and in this state, the power supply cable 6 and the guide tube 3 are inserted into the cavity of the pillar part. This is what I did.

[Problem that the invention attempts to solve]

However, the product previously proposed by the applicant has unstable quality because the power supply cable 6 is sharply bent near the plug 5, and the adhesive tape 11
If the guide tube 3 is stored in a rolled state for a long period of time, or if temperature changes occur, the adhesive of the adhesive tape 11 may adhere to the plug 5, causing poor conductivity. The adhesive tape 11 may peel off when inserting the power supply cable 6, or it may be difficult to remove the tape 11 after insertion, and furthermore, the outer diameters of the guide tube 3 and the plug 5 may be different, making temporary fixing with the adhesive tape 11 unstable. There was a problem with becoming. The purpose of the present invention is to provide a mounting jig for an in-vehicle antenna that can solve the problems of the applicant's previous proposal and also allows the guide tube and power feeding tube to be easily inserted into a vehicle. It is said that

[Means to solve the problem]

The in-vehicle antenna mounting jig according to the present invention includes a plug insertion tube that removably inserts and holds a plug provided at the free end of a power supply cable that connects to the power supply part of the in-vehicle antenna, and an antenna element. A tube fitting part that removably fits and holds the lower end of the guide tube is integrally connected with the axial directions thereof being arranged in parallel.

[Effect]

The in-vehicle antenna mounting jig according to the present invention is constructed as described above, so that it can be mounted with the plug inserted and held in the plug fitting tube and the guide tube fitted and held in the tube fitting part. By inserting the power supply cable and guide tube from the jig side into the vehicle's front pillar, etc., the power supply cable and guide tube can be easily inserted into the cavity, and the plug of the mounting jig can be easily inserted compared to wrapping adhesive tape. Since it can be easily and stably attached to and removed from the guide tube, it is possible to install the in-vehicle antenna with good work efficiency.Furthermore, even if the in-vehicle antenna with the mounting jig attached is stored for a long period of time, there will be no electrical problems. Furthermore, since the axial directions of the plug-fitting tube and the tube-fitting tube are parallel, the power supply cable does not bend sharply, and the power supply cable does not have a tendency to bend, thereby impairing workability.

【Example】

Hereinafter, Figures 1 to 5 will be described for one embodiment of the present invention.
This will be explained with reference to the figures. In FIGS. 1 to 5, reference numeral 12 denotes a mounting jig, which is made of an integrally molded synthetic resin such as polypropylene, into which the entire plug 5 is removably inserted. A plug fitting tube 13 which is elastically held by the guide tube 3 and a shaft-shaped tube fitting part 14 into which the lower end of the guide tube 3 is removably fitted and elastically held are arranged so that their axial directions are parallel to each other. They are connected together at one end 12a. One end 12a of the mounting jig 12 is tapered and configured to form the bottom of the plug fitting sleeve 13 and the tube fitting part 14, and the outer peripheral surface of the tube fitting part 14 is provided with a guide. tube 3
A pair of opposing protrusions 14a are formed in contact with the inner circumferential surface of. Furthermore, the other end of the plug fitting tube 13 is open, and a chamfer 13a is formed on the inner periphery of the opening, and a conical surface 14b is formed on the outer periphery of the other end of the tube fitting portion 14 over the protrusion 14a. It is formed. The mounting jig 12 configured as described above has the sixth
Feed section 4 of an on-vehicle antenna similar to the one shown in the figure
The entire plug 5 provided at the free end of the power supply cable 6 connected to is fitted into the plug fitting tube 13, and the guide tube 3 in which the antenna element 1 is housed is fitted into the tube fitting part 14. The state shown in FIG. 1 is established. In this state, even if it is stored for a long time, unlike the case with adhesive tape, there is no risk of adhesive adhering to the plug 5, and it also prevents dust from adhering to the plug 5, and serves as a protective cover. Also plays a role. And mounting jig 1
2 is inserted from the one end 12a side into the cavity of the front pillar through a hole provided in the roof of the automobile as in the case of FIG. inserted into the cavity. In this case, since one end 12a of the mounting jig 12 is tapered and the guide tube 3 and the power supply cable 6 are substantially parallel, they can be easily inserted. After being inserted into the cavity, the mounting jig 12 is pulled out and removed from the guide tube 3 and plug 5. In this case, the mounting jig 12 can be removed by pulling it out, making it easier to work with.
Since the power supply cable 6 does not have sharp bends, it does not have a tendency to bend, making it easy to connect the plug to the radio set body. Note that the same reference numerals in FIG. 1 as in FIG. 6 indicate corresponding parts.

[Effect of the idea]

As explained above, in the mounting jig of the present invention, the plug-fitting tube and the tube-fitting part are connected together with their axial directions parallel to each other. In addition, the plug provided at the free end of the power supply cable of the in-vehicle antenna is removably inserted into and held in the plug fitting tube, and the lower end of the guide tube is removably fitted into the tube fitting portion. By holding the cable and inserting the power supply cable and guide tube from the mounting jig side into a part of the vehicle such as the front pillar, this insertion work can be done easily and in a short time, and the work of attaching and removing the mounting jig is also easy. It is possible to easily and stably mount the vehicle-mounted antenna, and there are no electrical problems such as poor conduction of the plug.
