Description

[Detailed Description of the Invention] This invention relates to a portable type radio receiver, and its aim is to make it possible to make effective use of the space inside the cabinet while making it particularly thin.

Generally speaking, when trying to make a radio receiver thinner,
The installation of various electrical components within the cabinet poses a major problem, and in particular, the installation of electrical components such as electrolytic capacitors, which are difficult to miniaturize, requires ingenuity.

On the other hand, the arrangement of various electrical components to be stored in the cabinet is greatly influenced by how the space for the batteries to be stored in the cabinet is provided.

Now, if we take a battery storage space to the right of the lower end of a rectangular cabinet, we can create a storage space for electrical components to the left of the lower end of the cabinet, but in this case, how should we use that storage space? The big question is how to install the electrical parts.

The present invention has been developed in view of these points, and the radio receiver of the present invention will be described below with reference to drawings of embodiments.

Figures 1 and 2 show an example of the structure of the radio receiver of the present invention, and in the figures, 1 is a composite resin cabinet body, and 2 is a composite resin cabinet that is combined with the cabinet body 1. A lid body, 3 is a first printed wiring board housed and fixed in a cabinet consisting of the cabinet body 1 and the cabinet lid body 2, and 4 is a second printed wiring board housed and fixed in the cabinet. 5 is a leadless component such as a resistor attached to one surface of the first and second printed wiring boards 3 and 4; 6 is the first printed wiring board 3;
7a and 7b are electrical components such as an intermediate frequency transformer and a diode attached to the other surface of the second printed wiring board 4.
8 is a guide rib for positioning the side edge of the second printed wiring board 4 protruding from the inner surface of the cabinet body 1; This is a mounting boss that protrudes from the inner surfaces of the cabinet body 1 and the cabinet lid 2 and is used to hold the first printed wiring board 3 inside the cabinet when the cabinet body 1 and the cabinet lid 2 are combined.

Here, the second printed wiring board 4 is installed in a small space adjacent to the battery storage section 11 provided at the lower right side of the cabinet, and the second printed wiring board 3
Although it is smaller, it is slightly larger than the electrical component 7a that is attached to this second printed wiring board 4 and is turned sideways.

Although the first and second printed wiring boards 3 and 4 are separated, they are electrically connected by a lead wire 12, and an electrical component 7b attached to the second printed wiring board 4 is laid down horizontally in the surplus space adjacent to the battery storage section 11.

With this configuration, the second printed wiring board 4 has the electrical components 7a attached to it laid down horizontally onto the second printed wiring board 4, and the guide ribs 8 provided on the cabinet body 1
Therefore, when the cabinet main body 1 and the cabinet cover body 2 are combined, the electric component 7a can be pressed and fixed in the cabinet, and no other mounting screws are required. A small space in which the wiring board 4 is attached can be effectively utilized.

Moreover, since the center of the second printed wiring board 4 is held down by the smaller electrical component 7a, the holding effect of the electrical component 7a (and synergistic effect with the guide ribs 8) makes the mounting more reliable. be able to.

Note that the electrical component 7a mounted on the second printed wiring board 4 in a horizontal position is mounted on the first printed wiring board 3 and placed on the second printed wiring board 4 as shown in FIGS. 3 and 4. Alternatively, the first printed wiring board 3 may be installed upside down inside the cabinet as shown in FIG. 4.

As described above, according to the present invention, a second printed wiring board is provided that is auxiliary to the first printed wiring board installed in the cabinet, and the second printed wiring board is placed horizontally on the second printed wiring board. Since the electrical components are placed opposite each other, the cabinet itself can be made thinner, and when installing the second printed wiring board in a small space inside the cabinet, it can be held and held by the horizontal electrical components without using mounting screws. Its practical value is extremely great, as it allows the installation space to be used more effectively.
