In particular, a light portion 6 is provided at the tip of the antenna main body 5 to be turned on by transmitting and receiving a specific electromagnetic wave from the antenna main body, and the light portion 6 has a butterfly shape as shown in FIG. A decoration (model 7) imitating the shape is attached. The model 7 is integrally formed from a metal plate or a synthetic resin, and its surface is colored in various colors for each part. For example, the whole is made white, and black spots are formed on each of the portions, so that it is finished like a white butterfly. Then, the butterfly model 7 is fixed to the surface of the light portion 6 using an adhesive, a screw, or a metal fitting. When the material is a thermoplastic resin, it is also possible to heat-weld the model 7 using the same material as the lens forming the outer surface of the light portion 6.

Here, as shown in FIG. 3, for example, the light section 6 includes a metal base 8 fixed to the tip of the antenna body 5, a circuit board 9 mounted on the base, and a Translucent lens 1 placed on the base
0. The light emitting diode 11 (LED chip), the coil 12 (chip coil), and the rectifying diode 13 (Schottky diode chip) are surface-mounted on the circuit board 9 to form a resonance circuit. Then, the tip of the element 5A forming the core wire of the antenna body 5 is connected to the input portion of the circuit board 9, and the electromagnetic wave transmitted and received by the antenna body 5 is rectified by the diode 13 so that the connected light emitting diode 11 emits light. is there.

FIG. 4 shows the circuit diagram. As is clear from this figure, in addition to the light emitting diode 11, the coil 12, and the diode 13, the air discharge electrode 14 for obtaining a resonance point is incorporated in the circuit board 9, and the light emitting diode 1
The anode side of 1 is connected to the element 5A via the coil 12, while the cathode side is connected to the anode side of the diode 13 via the air discharge electrode 14 to form a series resonance circuit.

Then, the circuit board 9 is mounted on the base 8 as described above, and a lens 10 that transmits light emitted from a light-emitting diode 11 as a light source is mounted on the base 8 to constitute a light section 6. You. The aerial discharge electrode 14 is configured by bringing positive and negative electrodes close to each other, but this may be formed into a chip-type capacitor like other chip components and surface-mounted on the circuit board 9. The number and the color of the light emitting diodes 11 are not limited. For example, (GaP) LED or (GaAs)
P) Red LED consisting of LED, blue LED, orange LE
D, yellow LED, white LED, green LED and the like are used.

FIG. 5 is a perspective view showing the telescopic guide partially broken away. As clarified in this figure,
The expansion / contraction guide 4 is formed with a screw having a predetermined pitch on the outer periphery of the lower part thereof as a connection part 15 for mounting the antenna mounting part 2 of the mobile phone 1. An operation knob 16 and a spring 17 for urging the operation knob in the horizontal direction are built in the upper side of the telescopic guide 4. The operation knob 16 has one end as a head 16A slightly protruding from the outer peripheral surface of the telescopic guide 4 and the other end pressed by the spring 17 toward the head 16A. In the operation knob 16, a circular through hole 16B through which the antenna main body 5 passes is formed at a portion extending to the back side of the head portion 16A, and a locking means for locking the distal end of the antenna main body 5 by the through hole. Is composed. That is, according to the operation knob 16 urged by the spring 17 in the direction perpendicular to the axis of the antenna body 5, the edge of the through hole 16 </ b> B is located at the tip side of the antenna body 5 when the antenna body 5 is pushed down as described later. By locking, the movement in the axial direction can be restricted.

The operation knob 16 also has an unlocking function. That is, by pressing the head 16A against the elasticity of the spring 17, the engagement between the distal end portion of the antenna body 5 and the through hole 16B can be easily released. In FIG. 5, reference numeral 18 denotes an opening formed at the center of the distal end of the telescopic guide 4 so as to face the through hole 16B.
From 8, the antenna body 5 is extended outward.

Next, FIG. 6 shows a longitudinal section of the telescopic guide.
FIG. 7 shows a state where the antenna of the present application is disassembled. As is apparent from these figures, the elastic guide 4 has the above-described spring 17.
Separately, an elastic body 19 made of a compression coil spring and a ring-shaped washer 20 are incorporated. The elastic body 19 is built-in so as to be able to expand and contract along the axial direction of the antenna main body 5, and the antenna main body 5 is passed through the elastic body 19 and a washer 20 disposed on the elastic body 19. The elastic body 19 is provided inside the telescopic guide 4.
A cylindrical area 21 </ b> A that can store the elastic body 19 and the washer 20 is formed. Further, inside the telescopic guide 4, other areas 21B and 21C are formed above and below the area 21A. The operation knob 16 and the spring 17 described above are stored in the upper region 21B, and the lower end thereof is introduced into the lower region 21C when the antenna body 5 is extended.

In particular, a cylindrical plate spring 23 having a split groove is provided in the lower region 21C as a support for supporting the lower end of the antenna body 5 when the antenna body 5 is extended. The lower end is press-fitted. Here, the telescopic guide 4 is composed of a jig main body 4A that bisects a storage area 21A and a base 4B that is screw-connected to the jig main body so that the elastic body 19 can be stored. still,
The jig body 4A and the base 4B are integrated into a single jig body 4A.
There is also a form in which the upper end of the connection portion 15 is screwed into the connector.

On the other hand, the antenna body 5 has an element 5A made of a shape memory alloy or other conductor wire as a core wire, and is fixed to a resin-made sheath tube 5B into which the element 5A is inserted and one end (end) of the element 5A. It includes a conductive sleeve 5C and a terminal 5D fixed to the other end (lower end) of the element 5A, and the light portion 6 is provided at the tip thereof via the sleeve 5C as described above. Here, the sleeve 5
C has a concave constriction 24 as a portion to be locked by the through hole 16B of the operation knob 16, and the sleeve 5C has a diameter that cannot pass through the washer 20, and its end, that is, The connection portion with the sheath tube 5B is formed as a tapered pressure receiving portion 25. When the antenna body 5 is pressed down as shown in FIG. 6, the pressure receiving portion 25 is pressed by the elastic body 19 via the washer 20.

Here, the operation of the present antenna configured as described above will be described. First, as shown in FIG. 6, when the antenna main body 5 is pushed down and contracted, the antenna main body 5 is pressed while the pressure receiving portion 25 formed on the distal end side thereof is pressed by the elastic body 19 and urged in the distal end direction. The constriction 24 formed at the distal end is kept in a reduced state by being locked by the through hole 16B of the operation knob. And in this state,
The antenna body 5 can be extended simply by pressing the head 16A of the operation knob. That is, when the head portion 16A of the operation knob is pressed against the elasticity of the spring 17, the engagement between the through hole 16B of the operation knob and the constriction 24 of the antenna body is cut off. The antenna main body 5 in the state of being urged in the direction is vigorously ejected toward the distal end side by the restoring force of the elastic body 19. The elastic body 19
Is extended when the washer 20 reaches the upper end of the area 21A, but the antenna main body 5 continues to grow at the initial speed without resistance and is stopped when the terminal 5D at the lower end is introduced into the telescopic guide 4. . At this time, the terminal 5D is press-fitted into the inside of the leaf spring 23 and is supported.
Can be maintained in an extended state while being supported by.

On the other hand, in order to reduce the size of the antenna main body 5, it is sufficient to press the tip thereof. That is, when the tip of the antenna body 5 is pressed, first, the terminal 5D is
, And then the pressure receiving portion 25 comes into contact with the washer 20. Therefore, if the tip of the antenna body 5 is continuously pressed against the elasticity of the elastic body 19, the antenna body 5 descends while reducing the elastic body 19 by the pressure receiving portion 25, and then the tip end is engaged by the operation knob 16. Will be stopped. By the way, since the pressure receiving portion 25 has a tapered shape that becomes thinner toward the lower end side of the antenna main body 5, a load when the relevant portion passes through the through hole 16B of the operation knob is small, and the antenna main body 5 can be smoothly moved. Although the pressure can be reduced, the pressure receiving portion 25 may be a right-angled surface. At this time, the antenna main body 5 can be reduced smoothly while the operation knob 16 is pressed.

Next, when transmitting and receiving electromagnetic waves by the antenna body 5, the light section 6 is turned on by the action of the electromagnetic waves. That is, when an electromagnetic wave of a predetermined frequency is received by the antenna body 5 or an electromagnetic wave is transmitted through the antenna body 5, the light unit 6 provided at the tip thereof
Receives an electromagnetic wave distributed to the antenna body 5, rectifies this, and emits light from the light emitting diode 11, and the light is
And is radiated to the outside. For this reason, not only the ring tone but also the ring tone can be visually recognized at the time of an incoming call, and the antenna main body 5 becomes very prominent by the lighting of the light unit 6 and the butterfly model 7 during the call.

Here, the antenna of the present invention is preferably applied to one in which the extension operation can be performed with a single touch as in the above example, so that the butterfly model 7 does not obstruct the expansion and contraction operation of the antenna body 5. The present invention is not limited to the above example, and can be applied to a case where the expansion and contraction operation is completely manual.

For example, as shown in FIG. 8, a linear antenna main body 50 may be slidably passed through a cylindrical telescopic guide 40. Here, one end of the antenna body 50 is provided with a fixed terminal 50A that is locked inside the telescopic guide 40 so as to maintain its extended state, and the other end of the telescopic guide 40 is maintained at its other end to maintain its contracted state. The light section 6 is provided via a fixed terminal 50B locked inside. In particular, also in the antenna of this embodiment, a butterfly model 7 is attached to the light portion 6. According to the antenna of the present embodiment, the antenna unit 50 can be expanded and contracted by picking the light unit 6 and the butterfly model 7, and the antenna unit 50 can be complemented by the model 7 attached to the light unit 6 when extended. it can.

FIG. 9 shows a multi-stage antenna main body 51.
This is an example in which a butterfly model 7 is attached to the tip of a butterfly. here,
The antenna body 51 has several pipes 51A having different diameters,
, Which are sequentially fitted to each other so as to be extendable and contractible, and a light portion 6 is provided at the tip thereof similarly to the above example, and a butterfly model 7 is attached to the light portion 6.

Although the application example of the present invention has been described with reference to the drawings, the mobile communication antenna according to the present invention is not limited to a mobile phone, but is applied to a PHS terminal, a portable radio receiver, a transceiver, or the like. You can also. Further, the present invention preferably has a light portion that shines at the time of transmission and reception of electromagnetic waves at the tip of the antenna main body. However, an antenna body without such a light portion is provided, and a butterfly model is provided at the tip. It may be attached.

[0026]

As is apparent from the above description, according to the present invention, a model imitating a butterfly is attached to the tip of the antenna main body extended linearly from the main body of the communication device such as a portable telephone. Therefore, an aesthetic effect is obtained in that the antenna body becomes very prominent during communication or the like. In particular, when communicating while walking, it is possible to make the surroundings look like butterflies dancing by shaking the antenna body.

Also, since the butterfly model is attached to the light portion provided at the tip of the antenna main body, the synergistic effect further enhances the antenna main body, and furthermore, the visibility is reduced by the light portion and the model depending on the place of use. Can complement each other. In particular, in a dark place such as at night, a butterfly model shines in the lighting of the light unit, and in a bright place such as during the daytime, the butterfly model can be checked well even from a long distance, so that the visibility of the light unit can be compensated for.
