を有するアンテナの提供にある。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an antenna of a mobile transmitting / receiving device,
In more detail, an outer tube made of an insulating material such as synthetic resin, and a coiled conductive wire inserted inside to prevent resonance, is an antenna that is lightweight and flexible enough to enable various color tones. It is in the provision of an antenna that has.

伸縮式アンテナ(通称ロッドアンテナ)が周知、公知の
ものである。(Prior Art) As an antenna used in radios, televisions, radios, and the like as a mobile transmission / reception device, a telescopic antenna (commonly called a rod antenna) using a metal tube is well known and known.
いわゆる黄銅などの異径金属管にクロームメッキなどの
表面処理をし、各異径管材相互間に金属質弾性片を介装
して伸縮可能にしたテレスコープ状のロッドアンテナが
一般的である。A telescope-shaped rod antenna is generally used in which a metal tube of different diameter such as so-called brass is surface-treated by chrome plating or the like, and a metallic elastic piece is interposed between the respective different diameter tube materials to allow expansion and contraction.
このようなテレスコープ状のロッドアンテナは異径金属
管の相互の間に若干の間隙が形成されており、このため
異径金属管の相互間にがたつきが生じている。In such a telescope-shaped rod antenna, a slight gap is formed between the different-diameter metal tubes, which causes rattling between the different-diameter metal tubes.

れている。Then, particularly when used in audio equipment such as radio and television mainly for sound, the sound pressure generated from the audio equipment causes the rod antenna to resonate, which causes contact between different-diameter metals forming the rod antenna. Repeatedly, there is a problem that a so-called flicker sound is generated to make it difficult to listen to music or voice from an audio device, and as a countermeasure, there is one such as Japanese Utility Model Publication No. 58-966. It has been proposed to fit an elastic material such as resin or rubber to the inner surface of the upper end of the pipe located outside to prevent resonance.

ましくない、それぞれに欠点を有する。(Problems to be solved by the invention) In the above-mentioned conventional general type, an antenna element is made of a metal tube, and chrome plating is indispensable for the purpose of corrosion resistance, and only a single color is obtained. Absent.
However, in recent years, there has been a demand for a color that is the same as or harmonious with the cabinet color. When the rod antenna requires an electric length suitable for transmitted and received waves, for example, FM
For obi, the length should be around 80 cm. The length is considerably longer than that of the transmission / reception device, breakage accidents and the like are likely to occur, and the cost is increased if a resonance prevention structure is further provided. Therefore, the one disclosed in Japanese Patent Laid-Open No. 61-196602 has been proposed. That is, since the synthetic resin is adopted, the shape and color can be freely selected, and the expandable structure is made of the synthetic resin tube material, and the antenna element is formed into a coil shape.
Compared with the conventional rod-shaped rod antenna, it is 20-30% shorter and lighter, and even if it has flexibility, it can still be used by expanding and contracting, and because of its expandable structure, resonance prevention measures. It has not been done. Therefore, each of them has disadvantages that are not preferable for audio equipment.

Since such an antenna is manufactured by covering the coil spring with an insulating cylinder, a slight gap is formed between the coil spring and the insulating cylinder.

It is surrounded by a flexible insulating material and inserted, and one end of the coil-shaped conductive wire is connected to a connecting fitting fitted to one end of the outer cylindrical tube, and a sealing member is attached to the other end of the outer cylindrical tube. It is designed to be fitted.

In addition to being lightweight, the coil-shaped conductive wire can be obtained in a short length without the electric length of the antenna being substantially expanded or contracted, and the outer circumference of the coil-shaped conductive wire is surrounded by a flexible soft insulator. Since the conductive wire does not come into direct contact with the outer tube, the resonance action due to sound pressure can be prevented even when used in an audio device or the like.

ものにしてもよい。(Embodiment) Explaining an embodiment of the present invention as described above with reference to the accompanying drawings, as shown in FIG. 1, an outer cylinder tube 1 is formed by extrusion molding with an insulator such as synthetic resin, It is easy to obtain one that matches the color of the object to be mounted such as a cabinet. The connecting fitting 4 is provided with a protruding portion 4a, and one shown in the figure is a threaded member, and one end of the coil-shaped conductive wire 2 is screwed into the protruding portion 4a to fix the connecting wire. Further, the connection fitting 4 and the coil-shaped conductive wire 2 may be connected by other than screwing. The coil-shaped conductive wire 2 forms an electric length in the transmission / reception frequency band by the length of the outer tube 1 described above, and the outer circumference of the coil-shaped conductive wire 2 is a flexible soft insulator 3
Surround with. For example, a vinyl tube is cut in the axial direction, and the coiled conductive wire 2 is fitted from the cut portion. The thus-formed one is inserted into the outer tube 1, and the connection fitting 4 is fixed to the outer tube 1 by screwing or press-fitting it with an adhesive or the like. The other opening end of the outer tube 1 is formed by screwing the sealing member 5 or by press-fitting to insert and fix the antenna A. In this case, if the coiled conductive wire 2 and the insulator 3 are made to have a relationship of being contracted in the outer tube 1 by inserting the sealing member 5, a pressed state can be obtained in the outer tube 1. As a result, even if a vibration or the like is received, since the insulator 3 is inserted in a close contact, no flicker noise, that is, resonance action does not occur. Further, since the coiled conductive wire 2 is formed hollow, an antenna having excellent flexibility can be obtained even when the outer tube 1 is bent. FIG. 2 shows an example of mounting the antenna according to the present invention, which includes a mounting bracket 4
Shows the case where it is attached to the holder part 6 of the rotary bending mechanism.
The holder part 6 is attached to the cabinet, and the antenna A
Although the angle and direction of can be adjusted, it may be attached only to the bending mechanism, or may be directly attached to the attaching portion of the connecting fitting 4 by screw fitting. The outer tube 1 may have a round shape, a polygonal shape, or a groove, or may have a pattern.

Does not happen. Moreover, you can use colors that match the cabinet. Furthermore, an antenna with an electric length suitable for the transmitting and receiving frequency can be obtained without expansion and contraction, and since a soft insulator is interposed between the coil-shaped conductive wire and the outer tube, it will not be affected by the sound pressure even when used in audio equipment. It is possible to provide an antenna that produces no flicker noise, is easy to manufacture, and is relatively inexpensive, and has a large effect in practical use.
