An operation when the mobile phone 1 according to the present embodiment falls and collides with the ground or the like will be described.
When the mobile phone 1 falls and collides with the ground or the like, each housing is deformed so as to bend in the longitudinal direction. The first circuit board 70 in the operation unit side body 2 is deformed so as to be bent in the longitudinal direction P (longitudinal direction Y).

  Here, since the sub antenna 85 and the digital television antenna 86 are mounted on the second circuit board 80 different from the first circuit board 70, the sub antenna 85 and the digital television antenna 86 are not easily affected by deformation in the first circuit board 70. First, this prevents the sub antenna 85 and the digital television antenna 86 from being damaged.

  In addition, since the second circuit board 80 is disposed on the end side in the longitudinal direction Y of the operation unit side body 2, the second circuit board 80 is not easily affected by the bending deformation in the operation unit side body 2. In particular, since the second circuit board 80 is disposed on the side of the connecting portion 4 that has high rigidity and is difficult to be deformed, the second circuit board 80 is not easily affected by bending deformation in the longitudinal direction Y of the operation unit side body 2. This further suppresses damage to the sub antenna 85 and the digital television antenna 86.

  The second circuit board 80 is arranged so that the longitudinal direction R (third longitudinal direction) of the second circuit board 80 is substantially orthogonal to the longitudinal direction Y of the operation unit side body 2. In other words, the second circuit board 80 is arranged such that the short direction coincides (parallel) with the longitudinal direction Y or the like in the operation unit side body 2. That is, the second circuit board 80 is disposed so as not to be deformed by bending in the operation unit side body 2. This further suppresses damage to the sub antenna 85 and the digital television antenna 86.

  That is, the sub antenna 85 and the digital television antenna 86 are hardly deformed in the longitudinal direction Y (P) even when the operation unit side body 2 and the first circuit board 70 are deformed so as to bend in the longitudinal direction Y (P). Since it is mounted on the second circuit board 80, damage is suppressed.

  Further, in the sub antenna 85 and the digital television antenna 86, the longitudinal direction Q (second longitudinal direction) is the longitudinal direction Y (fourth longitudinal direction) in the operation unit side body 2 and the longitudinal direction P (first direction) in the first circuit board 70. 1 longitudinal direction). In other words, the sub-antenna 85 and the digital television antenna 86 have the short direction coincided with the longitudinal direction P (first longitudinal direction) of the first circuit board 70 and the longitudinal direction P (first longitudinal direction) of the first circuit board 70. (Parallel) are arranged.

  That is, the sub antenna 85 and the digital television antenna 86 are arranged so as not to be deformed even if the second circuit board 80 is deformed. Thereby, the damage in the sub antenna 85 and the digital television antenna 86 is suppressed.

Further, the impact and vibration transmitted to the first circuit board 70 due to the fall are absorbed by the leaf spring terminals 74 and are not easily transmitted to the second circuit board 80.
Further, a leaf spring terminal 74 is disposed on the third surface 82 side on the free end side of the second circuit board 80, and a spring pin terminal 84 is disposed on the fourth surface 83 side so as to be free. The vibration generated on the end side is suitably absorbed.

  That is, the impact or vibration generated by dropping or the like is not transmitted to the second circuit board 80 or is quickly absorbed. Thereby, it is suppressed that the sub antenna 85 and the digital television antenna 86 mounted on the second circuit board 80 are damaged.

According to the mobile phone 1 of the present embodiment, the following effects are exhibited.
According to the present embodiment, the sub antenna 85 and the digital television antenna 86 are arranged such that the longitudinal direction Q (second longitudinal direction) is substantially orthogonal to the longitudinal direction P (first longitudinal direction) of the first circuit board 70. The Accordingly, the sub antenna 85 and the digital television antenna 86 are prevented from being damaged even when the mobile phone 1 is subjected to an impact such that the first circuit board 70 is bent in the longitudinal direction P.

(Longitudinal direction). Thereby, the deformation | transformation which arises when the 2nd circuit board 80 receives the impact which the 1st circuit board 70 bends in the longitudinal direction R to the mobile telephone 1 is suppressed. Accordingly, the sub antenna 85 and the digital television antenna 86 are suppressed from being damaged even when the mobile phone 1 is subjected to an impact such that the first circuit board 70 is bent in the longitudinal direction P.

  Further, according to the present embodiment, the second circuit board 80 on which the sub antenna 85 and the digital television antenna 86 are mounted has the longitudinal direction R (third longitudinal direction) in the longitudinal direction Y (first direction) in the operation unit side body 2. 4 (longitudinal directions) are arranged so as to be substantially orthogonal. Thereby, the deformation | transformation which arises when the 2nd circuit board 80 receives the impact which the operation part side housing | casing 2 bends in the longitudinal direction Y to the mobile telephone 1 is suppressed. Accordingly, the sub antenna 85 and the digital TV antenna 86 are prevented from being damaged even when the mobile phone 1 is subjected to an impact that causes the operation unit side body 2 to bend in the longitudinal direction Y. .

  According to this embodiment, the first circuit board 70, the second circuit board 80 that is at least partially opposed to the first circuit board 70 and is smaller than the first circuit board 70, and the second circuit board 80 The antenna element 91 disposed opposite to the side opposite to the first circuit board 70 side and the thickness of the second circuit board 80 mounted on the first circuit board 70 and in contact with the second circuit board 80 A conductive leaf spring terminal 74 for urging the second circuit board 80 in the direction toward the antenna element 91 and the second circuit board 80 mounted on the second circuit board 80 side and in contact with the antenna element 91 side And a conductive spring pin terminal 84 that biases the second circuit board 80 toward the first circuit board 70 in the thickness direction of the board 80.

  Therefore, the second circuit board 80 is flexibly held by the urging force of the leaf spring terminal 74 and the spring pin terminal 84 so as to absorb an impact in the thickness direction Z of the operation unit side body 2. Therefore, even when an impact such as a drop is applied to the second circuit board 80, the impact is absorbed by the leaf spring terminal 74 and the spring pin terminal 84, so that the impact on the second circuit board 80 is reduced. And the bending of the 2nd circuit board 80 is suppressed. As a result, for example, damage to the sub antenna 85 mounted on the second circuit board 80 or the digital television antenna 86 due to impact such as dropping can be suppressed.

  Further, since the second circuit board 80 is smaller than the first circuit board 70, the bending with respect to an impact such as dropping is suppressed. Therefore, it is possible to further prevent damage to the sub antenna 85 and the digital television antenna 86 that are mounted on the second circuit board 80.

Therefore, the cost required for connectors and cables can be reduced.

  Further, according to the present embodiment, the leaf spring terminal 74 and the spring pin terminal 84 are disposed substantially opposite to each other with the second circuit board 80 interposed therebetween. Therefore, the second circuit board 80 is supported by the leaf spring terminal 74 and the spring pin terminal 84 through the second circuit board 80 at the same position on the third surface 82 and the fourth surface 83. Therefore, the second circuit board 80 is flexibly held by the leaf spring terminal 74 and the spring pin terminal 84 so as to absorb an impact in the thickness direction Z of the operation unit side body 2. Therefore, it is possible to absorb an impact such as a drop, so that the bending of the second circuit board 80 can be suppressed. As a result, the sub-antenna 85 mounted on the second circuit board 80 and the digital TV antenna 86 can be prevented from being damaged due to impact such as dropping.

For this reason, after the second circuit board 80 is disposed, one end of the second circuit board 80 is fixed by the fixing portion 115, thereby improving workability in the subsequent assembly work.
Further, since the free end side is held by the leaf spring terminal 74 and the spring pin terminal 84, the one end side of the second circuit board 80 is securely fixed to the fixing portion 115 and the free end side at the time of impact such as dropping. Then you can absorb the shock. Therefore, the bending of the second circuit board 80 can be suppressed. Therefore, damage to the sub antenna 85 and the digital television antenna 86 mounted on the second circuit board 80 can be suppressed.
