Although not shown in FIG. 4, the first housing 3 is provided with a battery that can be detached from the back side of the first housing 3, for example.
FIG. 3 is a rear perspective view of the first housing 3 side. On the back surface on the first housing 3 side, a lid 17 for the battery housing portion is disposed.

FIG. 5 is an exploded perspective view of the first housing 3. However, in order to prevent complication, FIG. 5 mainly shows components (cases) of the housing and main components such as a substrate housed in the housing. A configuration that is not shown is hereinafter referred to as “(not shown)”. In FIG. 5, the longitudinal direction (L) and the width direction (W) of the first housing 3 are indicated by arrows.
6A and 6B are enlarged perspective views of the antenna. 7 is a schematic cross-sectional view taken along line AA in FIG.

  As shown in an exploded view in FIG. 5, the mobile phone 1 includes a front case 11 that constitutes a front side portion of the first housing 3, an inner case 13 that constitutes an inner side portion of the first housing 3, 1 has a rear case 15 and a lid 17 (see FIG. 3) constituting the back side portion of the housing 3.

  The mobile phone 1 includes a key sheet 19, a flexible printed wiring board (FPC) (not shown), a shield case 21, a main board 23, and the like disposed in order from the front case 11 side in the first housing 3. It has a sub-board assembly 25 and a battery (not shown).

The inner case 13 can be generally divided into a first box-shaped part 131 whose front case 11 is opened and a second box-shaped part 132 whose rear case 15 is opened. A partition wall 133 exists between the first box-shaped part 131 and the second box-shaped part 132. A side wall 134 of the second box-shaped part 132 extends in the longitudinal direction (L) from one end in the width direction (W) of the partition wall 133. A long antenna holding plate 135 facing the front side and the back side is formed along the long side of the side wall 134 on the front side (lower side in FIG. 5).
The first box-shaped portion 131, the second box-shaped portion 132, the partition wall 133, the side wall 134, the antenna holding plate 135, and other inner case constituent portions that are not described are integrally formed of resin or the like.
The side wall 134 and the antenna holding plate 135 have a space defined by a wall having an L-shaped cross section so that the antenna element does not protrude from the box-shaped outer shell of the entire first housing 3 during housing. Form.

  The front case 11 is generally formed in a box shape thinner than the inner case 13 with the inner case 13 side opened. The front case 11 is a member that covers the inner case 13 from the front side and covers the front side of the inner case 13.

  The rear case 15 is generally formed in a box shape thinner than the inner case 13 with the inner case 13 side opened. An opening 151 for taking in and out a battery (not shown) is formed on the rear side of the rear case 15. The rear case 15 covers the inner case 13 from the back side. At this time, the rear case 15 mainly covers the first box-shaped portion 131 side of the inner case 13 and surrounds the width direction (W) side wall and the longitudinal direction (L) side wall of the inner case 13.

  The lid 17 is formed in a substantially plate shape having a shape and size substantially the same as the opening 151 on the back side of the rear case 15. The lid body 17 is disposed in the opening 151 on the back surface side of the rear case 15 and functions as a lid of the second box-shaped portion 132 that houses the battery.

  Thus, the inner case 13 is wrapped by the front case 11, the rear case 15, and the lid body 17. That is, the front case 11, the rear case 15, and the lid body 17 constitute an outer casing that encloses the inner case 13 that is an inner casing.

  The front case 11, the inner case 13, the rear case 15, and the lid body 17 are each mainly formed of, for example, a nonconductive resin. However, the inner case 13 is formed of a resin having a higher rigidity than the resin constituting the exterior casing, for example, by mixing a glass filler into the resin. Further, the inner case 13 is formed thicker than the outer casing. Therefore, the inner case 13 has higher strength against shearing and bending than the outer casing.

  The front case 11, the inner case 13, and the rear case 15 are fixed to each other by, for example, screws or engaging portions or both. The lid 17 is detachably fixed to the inner case 13 or the rear case 15 or both by an engaging portion or the like.

  At this time, as shown in FIG. 5, the key sheet 19, the FPC (not shown), the shield case 21, the main board 23, and the sub board assembly 25 are sandwiched by the front case 11 and the inner case 13 in the stacking direction of these members. Is done. The battery (not shown) is housed in the second box-shaped portion 132 of the inner case 13, and the rear case 15 and the lid body 17 (see FIG. 3) prevent the battery from dropping out from the inner case 13.

  On the other hand, in the front case 11, a plurality of keys 35 that accept user operations are exposed (see FIG. 1). The front case 11 includes a case main body 111 formed in a frame shape, and a key component 112 made of a relatively low rigidity material that is bonded to the case main body 111 so as to close the opening of the case main body 111. . The key component 112 is formed so that it can be easily bent in response to a user's pressing.

The key sheet 19 is made of a non-conductive elastic member having a water shielding property (not permeable to water) such as rubber, and is supported by the shield case 21 via a flexible substrate (FPC) (not shown). Configured. The key sheet 19 covers a plurality of switches. The switch of the key sheet 19 is normally formed in a dome shape on the FPC, and a dome-shaped movable contact can be brought into contact with a fixed contact provided at the center of the dome by a pressing force of the user.
The shield case 21 is made of, for example, metal, and contributes to improving the strength of the first housing 3. The shield case 21 may be configured by providing a conductive layer such as a metal layer on the surface of a non-conductive substrate such as resin. The shield case 21 covers and shields the main board 23 from the front case 11 side.

  The main board 23 is constituted by, for example, a rigid circuit board based on a hard resin. A plurality of electronic components are mounted on the main board 23. The main substrate 23 is formed with a ground pattern extending vertically and horizontally so as to divide the mounting surface into a plurality of regions.

In FIG. 7, a cross section in the width direction (W) of the first housing 3 corresponding to the first box-shaped portion 131 appears.
A ground pattern 23 </ b> A is formed on the main substrate 23. The ground pattern 23 </ b> A is appropriately disposed also inside the periphery of the main surface of the main substrate 23, and is formed around the periphery of the periphery of the main substrate 23, thereby depending on the components mounted on the main substrate 23. It also has the effect of shielding the circuit. The ground pattern 23A is electrically connected to the shield case 21.
In the cross section of FIG. 7, the end of the main substrate 23 approaches the wall plate 131 </ b> B that constitutes the first box-shaped portion 131 together with the back plate 131 </ b> A.

The rear case 15 is provided with an antenna holding portion 152. The antenna holding part 152 has a front-side shape that fits an L-shaped cross section formed by the side wall 134 that forms part of the inner case 13 and the antenna holding plate 135. On the rear side of the antenna holding portion 152, a semicircular groove 153 for accommodating the antenna 81 (more precisely, the rod-shaped antenna element 81A) is formed.
The antenna holding part 152 has a space in which the base part (shaft rotating part) of the antenna element 81 </ b> A of the antenna 81 is accommodated on one end side of the groove 153.

FIG. 6A shows an enlarged perspective view of the antenna 81. Note that FIG. 6B is a perspective view of the antenna 81 illustrated in FIG.
As shown in FIG. 6A, the antenna 81 is mainly composed of a rod-shaped antenna element 81A, a shaft rotating portion 81B, and an antenna fixing portion 81C.

The antenna fixing portion 81C further includes a skirt portion 811 in which the shaft rotating portion 81B is disposed near one end portion, and a fixed connection portion 812 extending in an L shape with respect to the other end portion of the skirt portion 811. .
After the antenna 81 is attached, the skirt portion 811 is disposed along the wall surface plate 131B of the first box-like portion 131, as shown in FIG. Further, the fixed connection portion 812 is disposed on the back plate 131A of the first box-shaped portion 131.

The fixed connection portion 812 of the antenna 81 has a screw hole 813 on the skirt portion 811 side. The fixed connection portion 812 has a cylindrical or polygonal columnar projection 814 on the back surface (more precisely, the front side surface) of the screw hole 813 toward the inside of the housing, as shown in FIGS. 6B and 7. . A connection terminal 815 having a smaller diameter protrudes from the line end surface of the protrusion 814.
The back plate 131A of the first box-shaped portion 131 is formed with a female screw hole corresponding to the screw hole 813 of the antenna fixing portion 81C and an antenna connection hole having a size corresponding to the protruding portion 814.

The antenna fixing portion 81C has a female screw hole and a screw 82 by passing the screw 82 through the screw hole 813 and turning the screw 82 with a screwdriver or the like in a state where the projection 814 is dropped into the antenna connection hole of the first box-like portion 131. Screw together. Thereby, the antenna 81 is fixed to the first box-shaped portion 131. In addition, although the screw fixing part is one place, the antenna 81 is firmly fixed to the first box-like part 131 because it is the two-point support fixing in which the protrusion 814 and the antenna connection hole are engaged.
At this time, the connection terminal 815 protruding from the front end surface of the protrusion 814 is connected to a predetermined “feeding portion” of the sub-board assembly 25 already arranged in the first box-shaped portion 131.

Here, correspondence between each part shown in FIG. 7 and the present invention will be described.
The inner case 13 (strictly speaking, the first box-shaped portion 131 which is a part of the inner case 13 is an example of the “casing”. The outer surface of the wall plate 131B corresponds to an example of a “first outer surface” of the housing, and the outer (back surface) surface of the rear plate 131A corresponds to an example of a “second outer surface”.
Both the main board 23 and the sub board assembly 25 constitute a “circuit board”, the ground pattern 23A corresponds to the “ground pattern”, and the conductive layer to which the connection terminal 815 is connected on the sub board assembly 25 is “feeding power”. This corresponds to an example of “part”.

A part of the antenna element 81A and the shaft rotating part 81B of the antenna 81 corresponds to an “antenna”, and another part of the shaft rotating part 81B and the antenna fixing part 81C correspond to an example of an “intermediate member”.
Here, the other part of the shaft rotating part 81B is a bearing part that protrudes outward from the skirt part 811. The part of the shaft rotating part 81B is a shaft that is rotatable on the bearing part via a rotating shaft. This is the base of the stopped antenna element.
The skirt portion 811 of the antenna fixing portion 81C corresponds to an example of “first portion of the intermediate member”, and the fixed connection portion 812, the protruding portion 814, and the connection terminal 815 correspond to an example of “second portion of the intermediate member”.
The hole (antenna connection hole) of the back plate 131A through which the protrusion 814 passes corresponds to an example of a “first opening”. The female screw hole of the back plate 131 </ b> A that engages with the screw 82 corresponds to an example of a “second opening”.

Here, the antenna element 81A is a main radio wave transmission / reception part (antenna element) of the antenna 81. However, the antenna element 81A functions as an antenna element in a broad sense including the shaft rotating portion 81B, the antenna fixing portion 81C, the protruding portion 814, and the connection terminal 815 that are electrically and mechanically connected. As a result, the effective antenna length of the antenna 81 is greater than the antenna length of the antenna element 81A alone, and the antenna characteristics are improved.
The antenna element 81A, the shaft rotating portion 81B, the antenna fixing portion 81C, the protruding portion 814, and the connection terminal 815 may be formed from the same conductive material, or may be formed from a plurality of different conductive materials as appropriate.

  Here, an O-ring (packing) 55 is disposed around the protrusion 814 in the state shown in FIG. 7 in which the protrusion 814 is inserted into the antenna connection hole of the back plate 131A. A recess that is one step lower than the contact surface of the back plate 131A with the fixed connection portion 812 is formed around the antenna connection hole, and a protrusion 814 in which the O-ring 55 is inserted is dropped into the recess. When the screw 82 is fastened, the O-ring 55 is crushed and the gap in the recess is filled to achieve waterproofing. Therefore, moisture from the outside does not enter through this antenna connection hole.

  The surface on which the shaft rotating portion 81B is located (wall surface plate 131B) is different from the surface of the back plate 131A provided with a hole (antenna connection hole) as the first opening. In the example shown in FIG. 7, the shaft rotating portion 81B is not directly provided on the wall surface plate 131B, but the shaft rotating portion 81B may be formed directly on the wall surface plate 131B. In that case, the stress is applied to the wall surface plate 131B by the movement of the antenna 81, but since the antenna connection hole is formed in the back plate 131A different from the wall surface plate 131B, the stress is transmitted to the antenna connection hole side to reduce the waterproof effect. Is suppressed.

On the other hand, in the example shown in FIG. 7, since the shaft rotating portion 81B is fixed to the skirt portion 811 of the antenna fixing portion 81C, the stress accompanying the antenna movement is transmitted to the antenna fixing portion 81C. However, there is a screwing location with the screw 82 between the fixing position of the shaft rotation portion 81B of the antenna fixing portion 81C and the location where the O-ring 55 on the antenna connection hole side is disposed. For this reason, it is prevented or suppressed that the stress accompanying the antenna movement is transmitted to the O-ring 55 side (antenna connection hole) side.
In another aspect, the second opening (screw hole 813) for screwing is different from the first outer surface side (wall surface plate 131B side) to which the antenna is fixed (the second outer surface side). It is formed on the back plate 131A side. Therefore, the external force for moving the antenna is not only prevented from lowering the waterproof effect, but is also prevented from being transmitted to the screwing portion and reducing the fixing force.

  Thus, the surface (outer surface of the back plate 131A) where the antenna connection hole to be waterproofed by the O-ring 55 and the like is formed is covered with the rear case 15. Therefore, the waterproof effect is further improved in that sense. In addition, since the screwing portion for substantially fixing the antenna 81 to the inner case 13 is also present on the surface covered with the rear case 15, the fixing force is reduced due to rust such as screws and other external actions. Reduction of waterproof effect is suppressed.

Here, the clearance between the outer diameter of the projecting portion 814 of the antenna fixing portion 81C and the inner diameter of the antenna connection hole is set to a minute clearance as long as both dimensional tolerances allow.
Conversely, the clearance between the outer diameter of the screw 82 and the inner diameter of the through hole (screw hole 813) formed in the fixed connection portion 812 is increased. That is, even if the center of the screw hole 813 is slightly deviated from the center of the female screw hole on the back plate 131A side with the protrusion 814 inserted into the antenna connection hole, the screw 82 is screwed through the screw hole 813. A possible clearance is set.
On the other hand, if the clearance on the screw hole 813 side is small, a load caused by screwing is applied to the protruding portion 814 side, and a uniform pressing force cannot be applied to the O-ring 55. In the present embodiment, the clearance on the screw hole 813 side is made sufficiently larger than the insertion clearance of the protruding portion 814 to prevent such a situation. As a result, a high waterproof effect by the O-ring 55 is obtained.

In addition, since the antenna 81 is fed (transmission / reception signal delivery) on the thickness direction side of the housing, reliable feeding connection is possible.
In addition, since a power feeding location where the ground pattern is not close to the power feeding section can be selected, a power feeding structure in which a high-frequency transmission signal or reception signal is hardly affected by the proximity of the ground pattern can be achieved. Reduction is suppressed.

  Furthermore, the distance between the shield case 21 and the power supply part of the circuit board (contact point of the connection terminal 815) is increased by making the power supply of the antenna 81 to the housing different from the surface on the antenna mounting side. For this reason, the deterioration of the antenna transmission / reception characteristics due to the proximity of the shield case 21 to the power feeding unit is suppressed.

  The present invention is not limited to the above embodiment, and may be implemented in various aspects.

  The mobile terminal is not limited to a mobile phone. For example, the mobile terminal may be a small wireless device (transceiver) or various electronic devices having a wireless communication function, such as a notebook computer, a PDA, a game machine, a camera, or the like. When the mobile terminal is a mobile phone, the role sharing between the first housing (the housing having the inner housing and the outer housing) and the second housing (the electronic component to be accommodated) is the reverse of the embodiment. It may be.

  In the case where the mobile terminal is a mobile phone, it is not necessarily limited to the description of the above embodiment whether the component shown by each block in FIG. 5 is provided in the first housing 3 or the second housing 5. For example, the antenna 81 and the imaging unit 89 may be disposed not only in the first housing 3 but also in the second housing 5. A part of the sound processing unit 77 and the image processing unit 79 may be provided in the second housing 5.

  According to the above embodiment and modification, the amount of crushing of the O-ring arranged for waterproofing can be kept uniform, and waterproof reliability is improved. The shape of the waterproof portion can be reduced, the distance between the metal fixing portion of the antenna and the substrate can be secured, and the electrical characteristics of the antenna are improved. Further, when the metal fixing portion of the antenna functions as an antenna element, the antenna arrangement area can be made compact while ensuring the necessary antenna length.
