[Technical field to which the invention belongs]

 The present invention relates to an antenna device for a portable communication device used for a portable communication device such as a mobile phone and a PHS (Personal Handyphone System).

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in a portable communication device such as a mobile phone and a PHS, an antenna device for a portable communication device having a linear antenna body has been used for transmitting and receiving radio waves. In general, the portable communication device is configured to emit a sound in order to notify that the incoming call has been received, but in order to visually notify the incoming call, a case member is attached to the main body of the antenna. An antenna device for a portable communication device in which a light emitting display circuit is disposed in the case member is also used.

[0003] The issue display circuit includes a rectifying diode electrically connected to the antenna body, and a light emitting diode (LED) that emits light by an output of the rectifying diode. The current flowing in the unit is rectified by the rectifying diode, and the LED is driven to emit light by the output of the rectifying diode, so that an incoming call to the portable communication device is visually notified.

[0004]

[Problems to be solved by the invention]

 In the conventional antenna device for a portable communication device, the case member and the antenna main body are integrated so that they cannot be removed. Therefore, since the combination of the antenna main body and the case member is limited to those that are sold, there are few various combinations that match the tastes of the user, and there is a problem that the selection range is narrow.

[0005] In addition, when replacing an antenna device that matches the user's preference according to the place of use or purpose of use, it is necessary to replace the entire antenna device including the antenna body. There was a problem that it became expensive.

Further, the color of the antenna main body is composed of a single black color. However, if the antenna is to be colored in various colors that match the user's taste, the coloring is likely to be peeled off after prolonged use. There was a problem. As a method of solving this, a method of forming a tube with a resin containing a dye and covering the antenna main body with the tube is considered, but it is necessary to make the diameter of the tube larger than that of the antenna main body. For this reason, there is a problem that the antenna portion composed of the antenna main body and the tube becomes thick as a whole, which is not preferable in terms of design in terms of smartness.

Further, when the antenna main body is housed in the portable communication device, there is a problem that the transmission / reception sensitivity of the portable communication device is deteriorated.

[0008] The present invention has been made in view of the above problems, and has as its object to provide an inexpensive configuration of an antenna device that meets the user's preference. Another object of the present invention is to provide an antenna device for a portable communication device that prevents the coloring from being peeled off when the antenna main body is colored, and is excellent in design. Another object of the present invention is to suppress deterioration of transmission / reception sensitivity when the antenna main body is housed in the portable communication device.

[0009]

[Means for Solving the Problems]

 An antenna device for a portable communication device according to the present invention includes a linear antenna main body, at least a part of which has a light-transmitting property, and a case member attached to the antenna main body; And a light emitting display circuit that emits light based on a current flowing through the antenna main body, the case member is attached to the antenna main body by a mounting member such as a screw. It is characterized by being detachably mounted. Thereby, the case member becomes detachable from the antenna main body.

[0010] The antenna body may be configured to be colored and to include a light-transmissive tube member that covers the antenna body. Further, the antenna main body may be formed of a shape memory alloy. A helical antenna electrically connected to the antenna body may be provided in the case member.

[Embodiment of the invention]

 FIG. 1 is a schematic front view of an antenna device for a portable communication device according to an embodiment of the present invention, showing an example of an antenna device for a mobile phone applied to a mobile phone. FIG. 2 is a partially enlarged sectional view of FIG. 1, and the same parts as those of FIG. 1 are denoted by the same reference numerals.

Has a conductive fixing member 108 that fits into the upper contact portion 105 and the lower contact portion 110.

The upper contact section 105 and the lower contact section 110 are formed integrally with the linear antenna section 106. The upper contact portion 105, the lower contact portion 110, and the linear antenna portion 106 are formed in a linear shape, for example, a linear shape as a whole. The upper contact portion 105, the lower contact portion 110, and the linear antenna 106 constitute the antenna main body 101.

The case member 104 is formed in a substantially cylindrical shape with a rounded upper part, attached to the tip of the upper contact portion 105 of the antenna main body 101, and at least a part thereof is formed of a member having light transmissivity. It is composed of a case top 102 formed of a light-transmitting member such as a light-transmitting resin and a case bottom 103 formed of a non-light-transmitting conductive metal.

Screws (not shown) are formed on the case top 102 and the case bottom 103, respectively, and these are integrated by screwing them together. Thereby, the case top 102 can be replaced (for example, it can be replaced with a case top having a different color).

A female screw part 208 is integrally formed at the center of the case bottom part 103, and is screwed with a male screw part 207 integrally formed on the upper part of the upper contact part 105, thereby forming a case. The member 104 is detachably attached to the upper contact portion 105, whereby the case member 104 is detachably attached to the antenna main body 101. Here, the male screw portion 207 and the female screw portion 208 constitute a mounting member for detachably attaching the case member 104 to the antenna main body 101, and also constitute a screw member.

With such a configuration, the case member 104 can be replaced (for example, a case member having a different color or a case member provided with the LED 202 that emits light of a different color).

As a mounting member for detachably mounting the case member 104 to the antenna main body 101, a convex portion is formed on one of the case member 104 and the antenna main body 101, and the other is fitted with the convex portion. The case member 104 may be detachably attached to the antenna main body 101 by forming a concave portion that fits. In this case, the protrusions and the recesses form a mounting member, and also form a fitting member.

On the other hand, as shown in FIG. 2, a helical antenna 201 which functions as an antenna and also functions as a spring member, a conductive pedestal 206, and a fixing means such as soldering or caulking to the pedestal 206 are provided in the case member 104. A printed circuit board 203 is provided which is fixed and electrically connected to the printed circuit board 203. The pedestal 206 is electrically connected to the antenna main body 101 via the case bottom 103 and the screw 207.

A light emitting diode (LED) 202 as a light emitting element, two rectifying diodes 204 and a smoothing capacitor 205 are fixed to the printed circuit board 203 by soldering.

The pedestal 206 is held in a state of being placed in the case bottom 103, and electrical contact between the pedestal 206 and the upper contact portion 105 is made by attaching the helical antenna 201 as described later. Realized by the power. The LED 202, the rectifying diode 204 and the smoothing capacitor 205 constitute a light emitting display circuit.

One (upper) of the helical antenna 201 contacts the inner wall of the case member 104 and the other (lower) contacts the pedestal 206, and the pedestal 206 is pressed downward by the extension force of the helical antenna 201. The pedestal 206 is in contact with the case bottom part 103 and the screw part 207.

Thus, the helical antenna 201, the pedestal 206, and the antenna body 101 are electrically connected. The light emitting display circuit provided on the printed circuit board 203 is electrically connected to the antenna main body 101 and the helical antenna 201 via the base 206. When the mobile phone transmits a radio wave, the one end of the helical antenna 201 is set to the point where the voltage is maximum (in other words, the point where the current is zero), and the pedestal 206 is located at the intermediate point. It is connected.

When assembling the antenna device for a mobile phone configured as described above, the upper contact portion 105 and the lower contact portion 110 are connected with the linear antenna portion 106 inserted into the tube member 107. The antenna main body 101 is formed by attaching to the linear antenna section 106 by a method such as caulking, and thereby the linear antenna section 106 is covered with the tube member 107.

Next, the printed circuit board 203 to which the LEDs 202 and the like are soldered and the pedestal 206 integrated with the printed circuit board 203 are placed in the case bottom 103. Next, the helical antenna 201 is placed on the pedestal 206, and the case top 102 is screwed and attached to the case bottom 103 to complete the assembly of the casing member 104.

At this time, the helical antenna 201 is pressed and compressed by the inner wall of the case top 102, whereby the pedestal 206 is fixed while being pressed against the screw portion 207 and the case bottom 103. Therefore, the helical antenna 201 and the light emitting display circuit are electrically connected to the antenna main body 101 via the pedestal 206. Thereafter, the screw members 207 and 208 are screwed together to attach the case member 104 to the antenna unit 101, thereby completing the antenna device.

As described above, the helical antenna 201 and the light-emitting display circuit can be electrically connected to the antenna main body 101 without using a special mounting device and without performing a lot of complicated soldering work. It is possible to connect to the device, the configuration is simple, and the assembly is extremely easy.

Further, the antenna body 101 and the case member 104 can be removed and replaced with another combination. Further, even when the antenna main body 101 is housed in the mobile phone, the helical antenna 201 protrudes from the mobile phone, so that it is possible to suppress a decrease in the transmission / reception sensitivity, and based on the radio wave at the time of answering the incoming call. The light-emitting display circuit emits light, and it becomes possible to display an incoming call notification.

FIG. 3 is a circuit diagram according to the embodiment shown in FIGS. 1 and 2, and has a linear antenna portion 301 (corresponding to the linear antenna portion 106 in FIGS. 1 and 2). FIG. 3 is a diagram showing a helical antenna 302 (corresponding to the helical antenna 201 in FIG. 2) provided in a case member 104 and a light emitting display circuit formed on a printed circuit board 203.

In FIG. 3, a connection point between rectifying diodes 303 and 304 (corresponding to the rectifying diode 204 in FIG. 2) is connected to a connection point between the linear antenna unit 301 and the helical antenna 302. The anode and cathode of the rectifier diode 303, the anode and cathode of the rectifier diode 304, and the LED 306 (corresponding to the LED 202 in FIG. 2) are connected in series to form a closed loop.

A smoothing capacitor 305 (corresponding to the smoothing capacitor 205 in FIG. 2) is connected in parallel with the LED 306. The two rectifying diodes 303 and 304, the smoothing capacitor 305, and the LED 306 constitute the light emitting display circuit. The rectifier diodes 303 and 304 and the smoothing capacitor 305 constitute a drive circuit. The rectifying diodes 303 and 304 are constituted by Schottky barrier diodes having a small voltage drop, and constitute a circuit.

When transmitting a radio wave from the mobile phone, for example, when receiving an incoming call from the mobile phone, an alternating current signal is output from a connection point between the linear antenna section 301 and the helical antenna 302, whereby the rectifying diodes 303 and 304 are output. An alternating current is supplied to the connection point. The AC current is rectified by the rectifying diodes 303 and 304, and then smoothed by the smoothing capacitor 305. The DC current is supplied to the LED 306, and the LED 306 emits light. Accordingly, when the mobile phone responds to the incoming call, the LED 306 emits light, so that the incoming light emission to the mobile phone is substantially displayed.

As described above, in the present embodiment, the linear antenna main body 101 and the case member 104 attached to the antenna main body 101 at least a part of which is translucent. And a light emitting display circuit that is provided in the case member 104 and emits light based on a current flowing through the antenna main body 101. The case member 104 includes a screw member, a fitting member, and the like. It is characterized in that it is detachably attached to the antenna main body 101 by the attaching member of (1).

Further, the antenna body is formed of a shape memory alloy. Further, a helical antenna 201 electrically connected to the antenna main body 101 is provided in the case member 104.

Therefore, by changing the combination of the antenna main body 101 and the case member 104 without replacing the entire antenna device, an antenna device that matches the user's preferences according to the place of use and the purpose of use can be obtained. It can be constructed at low cost.

Further, even when the linear antenna portion 106 is colored, it is possible to prevent the coloring from peeling off. Therefore, it is possible to apply various colors to the linear antenna section by various methods, and it is possible to select an antenna device that matches the user's preference, and to widen the selection range.

Further, since the colored linear antenna portion 106 is visually recognized through the translucent tube member 107, the linear antenna portion 106 thinner than the tube member 107 can be visually recognized from the outside. It gives a smart impression and is excellent in design. Furthermore, even when the linear antenna section 106 is formed of a shape memory alloy and is colored, it is possible to prevent the coloring from peeling off.

Still another object of the present invention is to suppress deterioration of transmission / reception sensitivity when the antenna main body is housed in the portable communication device. In addition, since the helical antenna 201 is provided inside the case member 104 and electrically connected to the antenna main body 106, the antenna main body 101 can be stored in a portable communication device. In addition, it is possible to suppress deterioration in transmission / reception sensitivity.

Although the present embodiment has been described with reference to the example of the antenna device for a mobile phone, the present embodiment can be applied to an antenna device for another portable communication device such as a PHS. Further, in the present embodiment, the antenna body 106, the helical antenna 201, and the light emitting display circuit are configured to be directly electrically connected. However, all or a part of them may be magnetically coupled or electrostatically coupled. It may be configured to be electrically connected using the wireless method.
