Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device suitable for use in various communication terminals such as a portable telephone device, and more particularly to an electronic device having an external terminal.

[0002]

2. Description of the Related Art Conventionally, a communication terminal such as a portable telephone device has been used.
Connected to an information processing device such as a small personal computer device or an electronic organizer device (hereinafter these devices are simply referred to as an information processing device) by a predetermined data transmission cable,
Processing such as transmitting information processed by the information processing device from the communication terminal or displaying information received by the communication terminal on the information processing device can be performed.

In this case, a connector is attached to one end of a cable connecting the communication terminal and the information processing device, and the connector is inserted into an external terminal provided on the communication terminal body. At the other end of the cable connecting the communication terminal and the information processing device, a card of a predetermined standard (for example, PCMCIA standard) is attached.
This card is inserted into a card slot of an information processing device conforming to the standard. Alternatively, on the side connected to the information processing device, instead of the card,
A connector or the like may be attached.

[0004] By the way, the terminal portion provided in such an electronic device such as a communication terminal has a structure having a certain strength so that the terminal portion is not damaged even if the connector is frequently inserted and removed. . That is, the terminal component itself constituting the terminal portion is attached by, for example, soldering to a circuit board of an electronic device, and the tip of the terminal component is exposed from a predetermined portion of the housing of the device. The connector is inserted into the connector. If the terminal is not reinforced at all, if the connector is inserted or removed, excessive force will be applied to the terminal, resulting in poor connection between the terminal and the board. Would.

[0005] For this reason, the mounting portion of the terminal component has been structured to be reinforced by some member. For example, at a location where the terminal component is exposed from the housing of the electronic device, the thickness of the resin case or the like constituting the housing is increased so that the position of the terminal component does not move. Or a reinforcing plate composed of a metal plate or the like is arranged around the terminal component, and the reinforcing plate is reinforced by the strength of the reinforcing plate.

[0006]

However, if the thickness of a resin case or the like forming the housing is increased to reinforce the mounting portion of the terminal component, the housing of the electronic device itself becomes large, and the size of the electronic device becomes large. This is a factor that hinders miniaturization.
In particular, in the case of a communication terminal such as a mobile phone device, downsizing is important and is not preferred. Further, in the case of a configuration in which a dedicated reinforcing plate for reinforcing the mounting portion of the terminal component is provided, the number of components constituting the device increases accordingly, and the manufacturing cost of the device increases, which is not preferable.

Although the terminal section for connecting the communication terminal and the information processing apparatus has been described here, the problems described here are common to various electronic devices having the terminal section.

SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to make it possible to easily and satisfactorily reinforce an external terminal provided in an electronic device.

[0009]

Here, the external terminal section 130 is subjected to a reinforcing treatment so that the mounting state does not become unstable even if the connector is repeatedly inserted and removed. The reinforcement processing in the present embodiment will be described below with reference to FIGS.

FIG. 1 shows a state in which the portable telephone device 100 having the structure described with reference to FIGS. 4 and 5 is folded, and the back surface of the first member 110 (the liquid crystal display unit 111 and the speaker 112).
FIG. 3 is a perspective view illustrating an internal configuration of a first member 110 with a housing constituting a surface (an opposite surface to a surface on which the is disposed) removed.

Inside the first member 110, there is disposed a printed circuit board 140 on which processing circuits for performing various signal processing required for the portable telephone device 100 are arranged. The circuit 141 and the second member 1
Various components such as a connector portion 142 connected to a key and a battery on the 20 side via a flexible substrate, an antenna 143 and the like are arranged. The substrate 140 itself is fixed to the housing constituting the first member 110 by, for example, screws.

Here, the circuit components constituting the portable telephone device 100 include a high-frequency circuit for performing reception processing and transmission processing of a radio signal as a high-frequency signal, and an intermediate frequency signal or a high-frequency signal received by the high-frequency circuit. It can be divided into a baseband signal and a baseband circuit that processes a signal for transmission processing in a high-frequency circuit. A portion where the high-frequency circuit is disposed on the substrate 140 is covered with a shield case 150. It is.

That is, a high-frequency circuit emits a high-frequency unnecessary wave according to the frequency of a signal to be transmitted or received (or a harmonic thereof) during signal processing in the circuit. A shield case 150 as a shield member for preventing radiation is provided so as to cover the entire portion of the substrate 140 where the high-frequency circuit is disposed.
The shield case 150 is formed by bending a sheet metal having an effect of shielding electromagnetic waves according to the shape of the shielded portion. Here, the shield case 150 of the present example is configured to also serve as a reinforcing member for the external terminal portion 130.

FIG. 2 is an enlarged view showing a portion where the shield case 150 is arranged, and FIG. 3 is a sectional view showing an arrangement state of the shield case 150. As shown in FIG. 3, high-frequency circuit component 144 is arranged on one surface 140 a of substrate 140, and shield portion 151 of shield case 150 is arranged so as to cover the entire high-frequency circuit component 144. I have. In this case, as shown in FIG. 4, predetermined portions such as the ends of the shield case 150 are fixed to the substrate 140 by soldering 152 or the like.

In this example, the shield case 1
An extension 153 is provided so as to protrude from the 50 shield part 151 to the side surface of the substrate 140.
3 is bent almost upright. The bent extension portion 153 has a through hole 154 having a shape substantially matching the outer shape of the external terminal portion 130.
The terminal component constituting the external terminal portion 130 is passed through 54. As shown in the cross section in FIG. 3, the terminal components constituting the external terminal portion 130 are attached to the other surface 140b of the board 140 by soldering, and are electrically connected to the circuit on the board 140.

As described above, since the external terminal 130 attached to the substrate 140 is passed through the through hole 154 provided in the extension 153 of the shield case 150, the external terminal 1
30 is held by the through hole 154, and the movement of the external terminal 130 is controlled by the extension 153 of the shield case 150.
Therefore, the shield case 150 functions well as a reinforcing member for the external terminal portion 130.

That is, even when an excessive force is applied when the connector is attached to or detached from the distal end portion 131 of the external terminal portion 130, the components constituting the external terminal portion 130 are removed from the through holes 154 of the shield case 150. Because you can not do
The external terminal portion 130 does not move with respect to the substrate 140, and the soldering state between the substrate 140 and the external terminal portion 130 does not become defective due to a force applied when the connector is attached or detached. In this case, as in this example, the external terminal portion 1 is formed by the through hole 154 having a shape substantially matching the external shape of the external terminal portion 130.
By performing the reinforcement process for restricting the movement of the connector 30, even if a force is applied in any direction when the connector is attached or detached (a direction other than the direction in which the connector is originally moved when the connector is attached or detached as shown by an arrow in FIG. 4), the external terminal portion 130 Movement will be regulated,
Reinforcement processing is performed favorably.

In the present embodiment, the terminal portion 130 is reinforced by the shield case 150, which is a shield member. Therefore, it is not necessary to separately provide a member for reinforcing the terminal portion 130. It can be as simple as that.

In this embodiment, the shield case 15
The components shielded by the shield case 150 are mounted on the other surface 140b of the substrate 140 since the components shielded by the shield case 150 are arranged on one surface 140a of the substrate 140 and the components constituting the external terminal portion 130 are mounted on the other surface 140b. Is almost completely covered, and the external terminal portion 130 can be reinforced, and the shielding effect is not impaired at all.
It is possible to achieve both a good shielding effect and a good effect of reinforcing terminal components.

In the example described in the above embodiment, the terminal portion 1 is simply inserted into the through hole 154 of the shield case 150.
30 but the extension 153 of the shield case 150 and the external terminal 13 are soldered or screwed.
0 may be directly fixed.

Further, in the example described in the above embodiment, the external terminal portion is passed through the through hole provided in the extension of the shield case, and the external terminal portion is held and reinforced by the through hole. Alternatively, a configuration in which the mounting position of the external terminal portion is reinforced by the shield case may be adopted by a configuration other than providing the through hole. For example, a configuration may be adopted in which the sheet metal forming the shield case and the external terminal portion come into contact with each other in any shape, so as to restrict the movement of the external terminal portion.

Further, in the example described in the above-described embodiment, the present invention is applied to the external terminal provided in the portable telephone device, but can also be applied to the case where the external terminal provided in another communication terminal is reinforced. In particular, in the example described in the above-described embodiment, the foldable mobile phone device is applied to a shape in which external terminals are provided on the side surface, but can be applied to communication terminals such as mobile phone devices of other shapes. In addition, the present invention can be applied to a case where external terminals provided in various electronic devices other than the communication terminal are reinforced.

[0030]

According to the first aspect of the present invention, a shield member for shielding a predetermined processing circuit portion is provided.
Since the terminal portion is reinforced, it is not necessary to perform a reinforcing process with a separate component, the terminal portion can be reinforced without increasing the number of components, and the terminal portion provided in the electronic device can be satisfactorily reinforced with a simple configuration. .

According to the second aspect of the present invention, in the first aspect of the present invention, a through hole substantially matching the external shape of the terminal portion is provided at a predetermined position of the shield member, and the through hole is passed through the through hole. By arranging the terminal portion in the state, the movement of the terminal portion is regulated by the through hole provided in the shield member, and the mounting portion of the terminal portion can be effectively reinforced.

According to the invention described in claim 3, in the invention described in claim 2, the processing circuit section is arranged on one surface of a predetermined substrate and the terminal section is arranged on the other surface of the substrate. Thus, as a shield member, a shield portion covering the processing circuit portion on one surface and a terminal reinforcing portion extending from the shield portion and having a through hole through which the terminal portion on the other surface is passed are provided. By using both sides of the board, it is possible to efficiently arrange the circuit parts that require shield processing and the arrangement of the terminal parts, and to shield the circuit parts disposed on both sides and reinforce the terminal parts. However, it can be performed favorably by one shield member.
