  As shown in FIG. 1 and FIG. 6, the lower unit 3 includes a control unit 14 that controls each part of the mobile phone body and a control unit 14 that are formed on a lower case that forms a foldable flat case. Wireless unit used for transmitting and receiving radio waves via the storage unit 15 for storing the processing program and various data to be stored, the built-in antenna 16, and the built-in antenna 16 and performing telephone calls and data communication according to a predetermined protocol. For example, an incoming call is notified by vibration, a communication unit 17, an operation unit 18 including a number of various operation keys for inputting numbers and characters, a transmission unit 19 including a microphone for inputting a transmission voice, and vibration. And a power supply unit 22 having a battery pack are mounted and schematically configured.

  Each of the lower housings is made of a synthetic resin molded product such as ABS resin and has a front case constituting the inner surface side and a rear case 25 constituting the outer surface side, and the combined front case and rear case 25 are combined. The control unit 14, the built-in antenna 16, the wireless communication unit 17, the operation unit 18, the transmission unit 19, the vibration unit 21, the power supply unit 22, and the like can be obtained by fitting or tightening with a fixture such as a female screw or a male screw. It is combined in a state of being housed or attached inside.

  As shown in FIGS. 1 to 5, the antenna mounting structure 26 of this example has two substantially cylindrical shapes protruding from the inner surface of the upper end portion (hinge portion side) of the rear case 25 constituting the lower housing. Pin-shaped ribs 27a and 27b are respectively formed on the flat plate-like built-in antenna 16 and the flat plate-like pressing member 28 for pressing and fixing the built-in antenna 16 from above (from the front case side of the lower housing). The built-in antenna 16 passes through the through holes 16a and 16b and the through holes 28a and 28b, and is sandwiched between the supporting ribs 29a and 29b and the support base 31 protruding from the inner surface of the rear case 25, and the pressing member 28. In addition, with the rear case 25 combined with the front case and coupled, the built-in antenna 16 is pressed from above by the pressing member 28 and fixed in a positioned state. It is configured.

From the inner surface of the upper end portion (hinge portion side) of the rear case 25, two substantially cylindrical pin-shaped ribs 27a and 27b and a support for supporting the built-in antenna 16 from below (from the inner surface side of the rear case 25). Ribs 29a, 29b are provided in a protruding manner.
The pin-shaped ribs 27a and 27b are substantially cylindrical, and are formed in a shape in which the ridge line is slightly inclined with respect to the axis of symmetry so that the thickness gradually decreases from the root toward the tip.
The thickness of the pin-shaped ribs 27a and 27b is substantially the same as or slightly smaller than the diameter of the through-holes 16a and 16b in the portion passing through the through-holes 16a and 16b of the built-in antenna 16, and the through-hole 28a of the holding member 28. , 28b is set to be substantially the same as or slightly thicker than the diameter of the through holes 28a, 28b.

Thereby, the built-in antenna 16 is supported from below by the support ribs 29a and 29b and the support base 31, and the through holes 28a and 28b are in a state where the pin-shaped ribs 27a and 27b pass through the through holes 16a and 16b. When the presser member 28 is moved closer to the built-in antenna 16, the pin-shaped ribs 27a and 27b are fitted into the through holes 28a and 28b, and the built-in antenna 16 is moved from above. It is fixed in a slightly deformed state so as to be pressed.
Note that the pin-shaped ribs 27 a and 27 b are rounded at the leading ends, and the height is set so that the leading ends are slightly exposed from the through holes 28 a and 28 b of the pressing member 28.

The two pin-shaped ribs 27a and 27b are arranged at positions slightly shifted (asymmetric positions) along the length direction of the rear case 25, and the built-in antenna 16 having a substantially left-right symmetric appearance is turned over. Incorrect mounting is prevented.
The support ribs 29a and 29b support the peripheral portion of the built-in antenna 16 so that the built-in antenna 16 is disposed at a predetermined height (position in the thickness direction of the rear case 25) in the rear case 25. The supporting rib 29b is formed integrally with the pin-shaped rib 27a (27b).
The support base 31 is disposed on the inner surface side of the rear case 25 and is used for elastically supporting and placing the back surface 16q of the built-in antenna 16. The mounting surface of the support base 31 is substantially the same as the height of the support ribs 29a and 29b. The support base 31 is made of an elastic member.

The holding member 28 is used to hold and fix the built-in antenna 16 from above, and through holes 28a and 28b for penetrating the pin-like ribs 27a and 27b are formed at the center.
The diameters of the through holes 28a and 28b are such that the pin-shaped ribs 27a and 27b are fitted in the height direction position (position in the thickness direction of the rear case 25) where the pressing member 28 is disposed. 27a and 27b are set so as to be substantially the same as or slightly smaller than the thickness of the corresponding part.
The position in the height direction at which the pressing member 28 is disposed is a position that is disposed on the built-in antenna 16 and presses the built-in antenna 16 from above with a predetermined pressing force. At this position, the presser member 28 is deformed so that the pin-shaped ribs 27a and 27b are fitted into the through holes 28a and 28b and slightly expanded.

The pressing member 28 is made of, for example, an elastic member such as silicone rubber, and has a buffer function for protecting the built-in antenna 16 from external force such as impact or bending force. Further, the material constituting the rear case 25 (pin-shaped ribs 27a, 27b) is predetermined by a sliding operation so that the state where the pin-shaped ribs 27a, 27b are fitted in the through holes 28a, 28b is maintained. A material capable of obtaining a frictional force greater than the value is selected.
The holding member 28 contacts the pressing portion formed on the inner surface side of the front case in a state where the rear case 25 is combined with the front case, and is pressed from the front case to be elastically deformed. 16 is also sealed and sealed to prevent moisture and dust from entering the housing from the hinge side.
That is, the back surface of the pressing member 28 is a flat surface 28p that contacts the front surface 16p of the substrate of the built-in antenna 16, and the surface of the pressing member 28 is a wall that contacts the edge of the opening near the hinge portion of the front case. A protrusion 28q is formed in a shape, and foreign matter is prevented from entering the inside from the side.

The built-in antenna 16 is configured by forming a thin film antenna element on a relatively small substrate having a substantially symmetric external appearance shape, and through holes 16a and 16b for penetrating the pin-shaped ribs 27a and 27b in the center. Is formed. The sizes of the through holes 16a and 16b are set to be approximately the same as or slightly larger than the thickness of the pin-shaped ribs 27a and 27b penetrating through these portions, so that the pin-shaped ribs 27a and 27b are not fitted into the through holes 16a and 16b. Has been. This avoids applying unnecessary external force to the built-in antenna 16.
The wireless communication unit 17 includes an RF circuit, a modulation / demodulation circuit, a baseband processing circuit, and the like. The wireless communication unit 17 modulates voice and data and transmits the radio wave via the built-in antenna 16 and transmits the radio wave via the built-in antenna 16. It is received and demodulated into voice and data, and used to make a call or data communication according to a predetermined protocol.

In order to attach the built-in antenna 16 to the mobile phone body, first, the support base 31 is fixed to a predetermined portion of the inner surface of the rear case 25. Pin-shaped ribs for fixing the support base 31 in a positioned state are formed on the inner surface of the rear case 25, and the support base 31 is inserted through the through-hole formed in the support base 31. Fix it.
Next, the built-in antenna 16 is gradually lowered by passing the pin-shaped ribs 27a and 27b through the through holes 16a and 16b with the back surface 16q facing the inner surface of the rear case 25 (the rear case 25). The back surface 16q is placed on the supporting ribs 29a and 29b and the support base 31 (close to the inner surface).

Next, the built-in antenna 16 is supported from below by the support ribs 29a and 29b and the support base 31, and the through holes 28a and 28b are provided with the pin-shaped ribs 27a and 27b passing through the through holes 16a and 16b. Is passed through the pin-shaped ribs 27 a and 27 b, and the holding member 28 is brought closer to the built-in antenna 16.
As a result, the pin-shaped ribs 27a and 27b are fitted into the through holes 28a and 28b of the pressing member 28, and the built-in antenna 16 is fixed in a slightly deformed state so as to be pressed from above. For example, the pressing member 28 is deformed and fixed so that the through holes 28a and 28b are slightly expanded by inserting the pin-shaped ribs 27a and 27b.

  Thus, after fixing the built-in antenna 16 to the rear case 25, the front case is combined with the rear case 25. The holding member 28 contacts the pressing portion formed on the inner surface side of the front case in a state where the rear case 25 is combined with the front case, and is pressed from the front case to be elastically deformed. In addition to pressing 16, the gap is closed and sealed to prevent foreign matter such as moisture and dust from entering the lower housing from the hinge side.

  According to the configuration of this example, the built-in antenna 16 is supported from below by the support ribs 29a and 29b and the support base 31, and the pin-shaped ribs 27a and 27b pass through the through holes 16a and 16b. Pin-like ribs 27a and 27b are fitted into the through holes 28a and 28b of the holding member 28, and the built-in antenna 16 is fixed in a slightly deformed state so as to be pressed from above. Further, the rear case 25 is combined with the front case. In the coupled state, the pressing member 28 comes into contact with a pressing portion formed on the inner surface side of the front case, and is pressed from the front case to be elastically deformed and presses the built-in antenna 16. It can be fixed securely.

  When the built-in antenna 16 is mounted, the built-in antenna 16 is lowered with the pin-shaped ribs 27a and 27b passing through the through holes 16a and 16b with the back surface 16q facing the inner surface of the rear case 25. Only the back surface 16q is placed on the support ribs 29a and 29b and the support base 31, and the size of the through holes 16a and 16b is substantially the same as or slightly larger than the thickness of the pin-shaped ribs 27a and 27b penetrating the portions. Since the pin-shaped ribs 27a and 27b are set so as not to be fitted into the through holes 16a and 16b, an excessive external force is applied to the built-in antenna 16 so that excessive deformation does not occur. Therefore, the built-in antenna 16 is not damaged or broken, and the yield can be improved and the reliability can be improved.

In addition, since the antenna fixing function is added to the sealing member used for waterproofing and dustproofing, there is no need to add a dedicated member, and there is no need to increase the number of processes during assembly.
Therefore, it is possible to ensure fixing and improve reliability in mounting the built-in antenna 16 without increasing the cost, without increasing the work time, and without preventing the thinning of the device. it can.
Further, since the built-in antenna 16 is detachable from the rear case 25, the built-in antenna 16 can be easily replaced. For example, unlike the method of fixing to a housing using a double-sided tape or the like, it can be easily removed and replaced.

This example differs greatly from the first embodiment described above in that the shape of the pin-shaped rib is changed to a substantially circular cross section, and the cross section is substantially rectangular.
Since the configuration other than this is substantially the same as the configuration of the first embodiment described above, the description thereof will be simplified.

  In the antenna mounting structure of this example, the pin-shaped rib has a substantially quadrangular shape (substantially rectangular shape in cross section), and the shape of the through-hole formed in the built-in antenna and the holding member is also substantially rectangular. Has been.

According to the configuration of this example, substantially the same effect as that of the first embodiment described above can be obtained.
In addition, positioning can be performed more reliably.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. Are also included in the present invention.
For example, in the above-described embodiment, the case where the built-in antenna is arranged on the upper end side (hinge part side) of the lower housing has been described. However, the present invention is not limited thereto, and the case where the built-in antenna is arranged on the lower end side of the upper housing. It can also be applied to.
Moreover, in order to ensure a predetermined characteristic, it is suitable for fixing a built-in antenna as an electric part of a mobile phone, but the present invention can be applied not only to the built-in antenna but also to other thin flat plate-like parts.

Further, the number of pin-shaped ribs is not limited to two, and three or more pin-shaped ribs may be provided, and the arrangement position may be a position corresponding to the central portion of the built-in antenna or a position corresponding to the peripheral portion. For example, if it has a corner | angular part, it is good also as only one.
Moreover, you may process the site | part inserted in the through-hole of the holding member of a pin-shaped rib so that the surface roughness may become comparatively large.
Further, the antenna member may be fixed by a dedicated pressing member, even if the pressing member does not serve as a seal member.
The shape of the through hole is not limited to a circle, but may be an ellipse, a polygon such as a triangle or a quadrangle, or an indefinite shape having a corner.

Although the case of using a synthetic resin casing has been described, it is not limited to a synthetic resin, for example, it may be a die-cast molded product made of a magnesium alloy, or may be made of another metal, or a synthetic resin is coated with a metal It is good also as a structure.
In addition to a foldable mobile phone that can only be opened and closed, a biaxial hinge allows the upper unit and the lower unit to be opened and closed with each other and to rotate perpendicular to the rotation axis for opening and closing. The present invention can also be applied to a mobile phone in which one unit is rotatably coupled to the other unit around the shaft, and can also be applied to straight type mobile phones other than the folding type.
Further, the antenna mounting structure of the present invention may be applied for permanent fixing or may be applied for temporary fixing prior to permanent fixing.

  As a mobile terminal, in addition to a mobile phone, the present invention can be applied to a simple mobile phone (PHS) terminal, a personal digital assistant (PDA), and a mobile computer. Further, as an electronic device, it can be applied to a computer having a wireless communication function in addition to a portable terminal.
