Next, a reference example of the antenna mounting structure of the electronic device will be described. Figure 4 is a perspective view showing a reference example of the antenna mounting structure of the mobile radio telephone. In FIG. 4, the portable radio telephone has a vertically divided telephone main body case composed of an upper case 61 and a lower case 71, and an antenna 51 is attached to the telephone main body case.
[0027]
The substantially cylindrical antenna 51 as a whole is disposed on an exposed portion 52 in which a transmitting / receiving element (not shown) is incorporated, a cylindrical mounting portion 53, and a surface of the mounting portion 53, and is electrically connected to the transmitting / receiving element. It is composed of a metal fitting 54 connected, an opening 55 provided at one end of the attachment portion 53, and a recess 56 formed between the metal fitting 54 of the attachment portion 53 and the opening 55.
[0028]
The upper case 61 is provided with a rib 62 that fits into the recess 56. The lower case 71 is engaged with an introduction portion 72 that introduces the attachment portion 53 and the opening 55 into the lower case 71 and an opening 55 introduced into the lower case 71 from the introduction portion 72. A hook 73 is provided. The upper case 61 and the lower case 71 are coupled by screws, claws or the like. At this time, the rib 62 and the hook 73 constituting the support portion cooperate to fix the antenna 1 to the telephone body case.
[0029]
The telephone body case incorporates an internal circuit and various electronic components for communication with a portable wireless communication device and the like, and these internal circuits and various electronic components are incorporated in an exposed portion 52 via a metal fitting 54. It is electrically connected to the transmitting / receiving element. A connector that is electrically connected to the internal circuit / various electronic components is provided on the periphery of the introduction portion 72. By connecting the metal fitting 54 to the connector, the internal circuit / various electronic components and the transmitting / receiving elements are connected. Electrically connected.
[0030]
Next, a structure for attaching the antenna 51 to the telephone body case will be described with reference to FIG. FIG. 5A is a perspective view showing the shapes of the antenna 51 and the hook 63, and FIGS. 5B to 5D are side views showing the structure of attaching the antenna 51 to the telephone body case step by step.
As shown in FIG. 5A, the hook 73 has a substantially cubic shape, and a slope is formed between a surface facing the opening 55 of the attachment portion 53 and a surface facing the upper case 61. Is formed.
[0031]
First, when the antenna 51 is inserted into the lower case 71 through the introduction portion 72 from the opening portion 55, as shown in FIGS. 5A and 5B, the opening portion 55 is hooked. 73 to face the state. When the antenna 51 is further inserted into the lower case 71, the end of the antenna 51 where the opening 55 is formed comes into contact with the hook 73. At this time, as described above, since the slope is formed on the hook 73, the end portion where the opening 55 of the antenna 51 is formed extends along the slope as shown in FIG. 5C. It slides up in the direction of the surface facing the upper case 61. Finally, as shown in FIG. 5 (d), the opening 55 is fitted into the hook 73 and is not easily detached from the hook 73.
[0032]
Thereafter, when the upper case 61 and the lower case 71 are overlapped with each other, the rib 62 provided on the upper case 61 is inserted into the concave portion 56 of the attachment portion 53 and fitted into the concave portion 56.

In the reference example , the attachment portion 53 may be made of an elastic material and have a curved shape. With such a configuration, when the upper case 61 and the lower case 71 are coupled, the attachment portion 53 receives pressure from the ribs 62 toward the lower case 71 by the ribs 62. An elastic force is applied to the peripheral edge of the hook and the base 73 a of the hook 73. Thus, in the antenna 51, the force that sandwiches the attachment portion 53 and the concave portion 56 by the rib 62, the peripheral edge of the introduction portion 72 and the base portion 73a of the hook 73, and the elastic force of the attachment portion 53 repelling this force interact with each other. By doing so, a frictional force is generated between the rib 62, the peripheral edge of the introduction portion 72, and the base portion 73 a of the hook 73, the attachment portion 3, and the recess portion 56, thereby firmly attaching to the body case.
[0035]
In the reference example , the attachment portion 53 has a substantially cylindrical shape. However, the shape of the attachment portion 53 is not limited to this, and can be freely modified and changed as long as the recess 56 is provided. can do.

Similarly, the shape of the opening 55 is not limited to the shape shown in FIGS. 4 and 5 as long as it can be engaged with the hook 73, and can be freely modified and changed as appropriate.
[0037]
Further, in the reference example , the concave portion 56 is not limited between the metal fitting 54 of the attachment portion 53 and the opening portion 55 as long as it is a place where the concave portion 56 can be fitted, and can be freely changed as appropriate.
[0038]
In the reference example , the upper case 61 may have a structure in which the rib 62 is provided on the upper case 11 having the insole structure disposed inside the main body case shown in FIG. Even with such a structure, the antenna 1 is firmly attached to the main body case by fitting the rib 62 and the recess 56.
[0039]
