Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to an antenna device of a small electronic device such as a portable receiver for individual calling (basing method).

Conventionally, in a portable receiver for individual calling, there is a technique in which a plate-shaped metal plate is attached to the outer surface of a case of the main body in which a wiring board that forms a transmission and reception circuit is installed, and this metal plate is used as an antenna. .

[Problems to be Solved by the Invention] In the prior art, since the wiring board and the metal plate are separately assembled in the case of the machine and they are electrically connected by a dedicated means, the number of parts and the assembly work process are There was an increasing problem.

"Means for Solving Problems" Therefore, the present invention is a small electronic device in which nameplates are fixed to the front and back surfaces of a case for housing a wiring board and each nameplate is formed of a metal material to serve as an antenna. In the antenna device, the lower end side of the wiring board is mechanically and electrically connected by a connection terminal along the bottom surface of the case of the machine, and the lower end side of each nameplate is mechanically attached by a mounting seat plate along the bottom surface of the case of the machine. Also, the nameplates are electrically connected, and the connection terminals and the mounting seat plate are integrally tightened with connection screws with the bottom surface of the case of the main body sandwiched therebetween, and each nameplate is electrically connected to the wiring board.

"Operation" Therefore, by inserting the wiring board from the top opening inside the case of this machine, and fitting the nameplate from the bottom to the outside of the case of this machine, just screw one screw into the bottom of the case of this machine. Assembling the wiring board and nameplate to the unit case,
The nameplate, which is the antenna, and the wiring board can be electrically connected at the same time, and the portable receiver for individual calling, which is equipped with the antenna, can be easily assembled.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings. First
FIG. 1 is a sectional side view of the individual calling machine, and FIG. 2 is an external perspective view of the same. It is equipped with a rectangular box-shaped synthetic resin case (1) .The top panel (2) is adhesively fixed to the top opening of the case (1), and a display board (3) that visually displays received messages is displayed. Mount to the top panel (2) via the display case (4).

In addition, a hanging hook (7) is provided on the back of the case (1) of the machine via a shaft (5) and a spring (6), and a slide switch button (8)
Also, a push switch button (9) is provided on the side surface of the case (1) of the unit.

In addition, a front nameplate that describes the product name or owner's name
(10) and rating nameplate indicating performance and power capacity (11)
In addition to the above, the front nameplate (10) and the rating nameplate (11) are formed of a metal antenna material to have an antenna function,
The front nameplate (10) is adhesively fixed to the front of the case (1), and the rating nameplate (11) is adhesively fixed to the back of the case (1).

Furthermore, as shown in FIG. 3, the lower end sides of the front nameplate (10) and the rating nameplate (11) are integrally connected by a mounting seat plate (12) made of the same material, and a case (this machine case ( 1) Bottom mounting hole (14)
The seat board (12) is joined to this part, the wiring boards (15) and (16) for reception and digital output are housed inside the case (1) of this machine, and the antennas are attached to the lower ends of the wiring boards (15) and (16). Solder and fix the connection terminal (17), and attach the antenna connection screw (18) to the unit case.
(1) It is inserted into the mounting hole (14) from the outside, and the screw (18) is screwed and fixed to the connection terminal (17).

Then, through the mounting seat plate (12), antenna connection screw (18), antenna connection terminal (17), front name plate (10) and rating name plate
Connect (11) to the wiring boards (15) and (16) and attach the front nameplate (10).
The rating plate (11) and the rating plate (11) function as an antenna.

"Effects of the Invention" As is apparent from the above embodiments, the present invention is a wiring board (15).
Nameplates on the front and back of the unit case (1) that houses (16)
(10) While fixing (11), each nameplate (10) (11) is formed of a metal material, in the antenna device of a small electronic device as an antenna, the lower end side of the wiring board (15) (16) Machine case
(1) Mechanically and electrically connecting with the connection terminals (17) along the bottom surface, and the lower end side of each name plate (10) (11) to the mounting seat plate (12) along the bottom surface of the machine case (1) Mechanically and electrically connecting with the connection terminal (17) and the mounting seat plate (12) with the connecting case (1) sandwiching the bottom of the case (1) of the unit, and tightening them integrally with each name plate (10). ) (11) is electrically connected to the wiring board (15) (16), and the wiring board (1
Insert the nameplates (10) and (11) from the bottom to the outside of the case (1) and insert one screw (18) to the bottom of the case (1). Assemble the wiring board (15) (16) and nameplate (10) (11) to the unit case (1) and screw the nameplate (10) (11) and the wiring board (15) (16) It is possible to make electrical connection at the same time, and it is possible to easily assemble an individual calling portable receiver or the like having an antenna mounted thereon, which is a practical effect.
