It consists of a hinge part 4 that can be connected.

図２は本体２の斜視図であり、図３は本体２の分解斜視図である。本体２は、フロントケース７と、リアケース９と、回路基板等を備えるユニットアッシー１０と、補強フレーム２０と、キーパッド３０と、から概略構成されている。   FIG. 2 is a perspective view of the main body 2, and FIG. 3 is an exploded perspective view of the main body 2. The main body 2 is schematically configured from a front case 7, a rear case 9, a unit assembly 10 including a circuit board and the like, a reinforcing frame 20, and a keypad 30.

フロントケース７とリアケース９とはユニットアッシー１０及び補強フレーム２０を内部に入れた状態で組み合わされ、ネジ８により止められて本体２の筐体をなす。また、フロントケース７にはキーパッド３０が配置される開口部７１が設けられている。   The front case 7 and the rear case 9 are combined with the unit assembly 10 and the reinforcing frame 20 placed inside, and are fastened by screws 8 to form a housing of the main body 2. The front case 7 is provided with an opening 71 in which the keypad 30 is disposed.

ユニットアッシー１０は、回路基板、フレーム等から概略構成されている。回路基板には、メインプロセッサ、メモリー、モデム、電源ＩＣ、アンテナ、メモリーカードスロット、インターフェイスコネクタ、イヤホンコネクタ等が設けられている。フレームは、例えばＭｇ合金等からなり、本体の強度を高めるとともに、電気的なグラウンドや電磁波シールドとしても機能する。   The unit assembly 10 is generally composed of a circuit board, a frame and the like. The circuit board is provided with a main processor, a memory, a modem, a power supply IC, an antenna, a memory card slot, an interface connector, an earphone connector, and the like. The frame is made of, for example, an Mg alloy and increases the strength of the main body and also functions as an electrical ground and an electromagnetic wave shield.

補強フレーム２０は、例えばＭｇ合金等からなり、フロントケース７の背面側であってユニットアッシー１０の前面側に配置される。補強フレーム２０の前面は平坦面となっており、この平坦面上には、図示しないキー基板が配置される。キー基板は、ドームスイッチのような可動接点と固定接点とを備えた薄型の押圧式スイッチが複数設けられたものであり、図示しないフレキシブルプリント基板等の配線によりユニットアッシー１０の回路基板と接続される。補強フレーム２０はキー押下操作を受け止め、補強フレーム２０とユーザの指との間に作用する圧縮荷重により可動接点を変形させて固定接点に当接させる役割を果たす。   The reinforcing frame 20 is made of, for example, Mg alloy or the like, and is disposed on the back side of the front case 7 and on the front side of the unit assembly 10. The front surface of the reinforcing frame 20 is a flat surface, and a key substrate (not shown) is disposed on the flat surface. The key board is provided with a plurality of thin pressing switches having a movable contact and a fixed contact such as a dome switch, and is connected to the circuit board of the unit assembly 10 by wiring such as a flexible printed board (not shown). The The reinforcing frame 20 receives the key pressing operation and plays a role of deforming the movable contact by a compressive load acting between the reinforcing frame 20 and the user's finger to contact the fixed contact.

キーパッド３０は、カーソルキー、決定キー、各種メニューキー、オフフックキー、オンフックキー、テンキー等のキー操作部５のキートップとなるものである。キーパッドの外周部はフロントケース７の外側から開口部７１の周縁部に接着される。   The keypad 30 is a key top of the key operation unit 5 such as a cursor key, a determination key, various menu keys, an off-hook key, an on-hook key, and a numeric keypad. The outer peripheral part of the keypad is bonded to the peripheral part of the opening 71 from the outside of the front case 7.

フロントケース７は、開口部７１が設けられているため、開口部７１の左右の側縁部が上下方向に細長く形成されている。このため、携帯電話機１を落下させた時等、フロントケース７に上下方向の圧縮荷重が加わった場合には、開口部７１の左右の側縁部が左右方向に変形し、破損する恐れがある。
そこで、本実施の形態においては、フロントケース７を補強するために補強フレーム２０を用いている。以下、その補強構造について説明する。 Since the front case 7 is provided with the opening 71, the left and right side edges of the opening 71 are formed to be elongated in the vertical direction. For this reason, when a vertical compressive load is applied to the front case 7 such as when the mobile phone 1 is dropped, the left and right side edges of the opening 71 may be deformed in the left-right direction and damaged. .
Therefore, in the present embodiment, the reinforcing frame 20 is used to reinforce the front case 7. Hereinafter, the reinforcing structure will be described.

図４はフロントケース７の背面を示す斜視図であり、図５は図４のV部の拡大図である。また、図６は補強フレーム２０の前面を示す斜視図であり、図７は図６のVII部の拡大図である。   4 is a perspective view showing the back surface of the front case 7, and FIG. 5 is an enlarged view of a portion V in FIG. 6 is a perspective view showing the front surface of the reinforcing frame 20, and FIG. 7 is an enlarged view of a portion VII in FIG.

図４、図５に示すように、フロントケース７には、開口部７１の左右の側縁部に沿って上下方向に間隔を空けて、背面から前面に貫通する複数の嵌合穴７２，７２，・・・が形成されている。また、図６、図７に示すように、補強フレーム２０の前面には、複数の嵌合穴７２，７２，・・・と対応する位置に、嵌合突起２１，２１，・・・が設けられている。この複数の嵌合穴７２，７２，・・・に嵌合突起２１，２１，・・・が嵌め込まれるようにフロントケース７と補強フレーム２０とが重ね合わされている。   As shown in FIGS. 4 and 5, the front case 7 has a plurality of fitting holes 72, 72 penetrating from the back surface to the front surface with a space in the vertical direction along the left and right side edges of the opening 71. Are formed. 6 and 7, the front surface of the reinforcing frame 20 is provided with fitting protrusions 21, 21,... At positions corresponding to the plurality of fitting holes 72, 72,. It has been. The front case 7 and the reinforcing frame 20 are overlapped so that the fitting protrusions 21, 21,... Are fitted into the plurality of fitting holes 72, 72,.

フロントケース７に上下方向の圧縮荷重が加わった場合でも、嵌合突起２１，２１，・・・が嵌合穴７２，７２，・・・に嵌め込まれているため、開口部７１の左右の側縁部が補強フレーム２０により拘束され、左右方向に変形するのを規正する。   Even when a vertical compressive load is applied to the front case 7, the fitting protrusions 21, 21,... Are fitted in the fitting holes 72, 72,. The edge portion is restrained by the reinforcing frame 20 and regulates deformation in the left-right direction.

このように、本実施の形態においては、フロントケース７に大きな開口部７１を設け、中央部が抜けた形状とした場合でも、開口部７１の左右の側縁部の変形を抑制するため、フロントケース７の破損を防止することができる。   As described above, in the present embodiment, the front case 7 is provided with the large opening 71, and even when the center part is formed in the shape, the deformation of the left and right side edges of the opening 71 is suppressed. The case 7 can be prevented from being damaged.
