Description

  The present invention relates to an electronic device such as a mobile phone.

  In recent years, with the advancement of functions in mobile phones, various connectors (such as a cable connector for connecting to an external device, a card connector for attaching an external memory, an earphone connector, etc.) are provided inside the housing. It has been. Electronic components such as connectors are mounted on a circuit board. Parts constituting the housing such as a circuit board and a shield case are housed in a housing case having an opening. The connector faces the opening and is exposed to the outside of the housing through the opening. The opening is closed by a cap as a closing member.

  There are various types of caps for closing the opening of the housing. For example, a cap having a main body portion fitted into the opening portion and an arm portion extending from the main body portion (“cap with arm portion”). ”). According to the cap with the arm portion, the cap portion is slidably held in the housing by inserting and arranging the arm portion inside the housing and slidably holding the arm portion.

  The cap with the arm portion affects the size of the housing depending on the structure. For example, in the case of a mobile phone in which the casing has a thin rectangular parallelepiped shape and the opening is provided on the side surface of the casing, the arm portion is arranged in the thickness direction of the casing with respect to the connector. In the case of a cap with an arm portion that is inserted into the housing, the connector and the arm portion are arranged in the thickness direction of the housing, which increases the thickness of the housing and hinders downsizing of the housing. .

  In the case of a cap with an arm portion that is inserted into the housing so that the arm portion is close to the side surface of the housing, the arm portion is disposed close to the side surface of the housing. The width of the body increases, and the size reduction of the housing is hindered.

  Further, in the case of a cap with an arm portion (see, for example, Patent Document 1 below) inserted into the housing so that the arm portion is arranged in the longitudinal direction of the housing with respect to the connector, the arm portion is close to the arm portion. The mounting area on the mounting surface of the circuit board is reduced, and downsizing of the housing is hindered. More specifically, since the arm portion inserted and arranged inside the housing can be rattled, electronic components are placed at positions on the circuit board that may come into contact with the arm portion when the arm portion rattles. Without mounting, contact between the electronic component and the arm portion is avoided. Therefore, an unused area is generated on the mounting surface of the circuit board.

  Such a problem may occur in portable electronic devices other than mobile phones, and may also occur in electronic devices other than portable electronic devices.

As shown in FIG. 7, the arm portion 92 is restricted from further movement in the X2 direction when the engagement protrusion 94 abuts against the first rib engagement portion 27a, the second rib engagement portion 27b, and the like. .

  As shown in FIG. 7A, when the cap 90 is pulled out from the operation unit side body 2, the opening 25 opens and the connector 81a is exposed. In the state where the cap 90 is simply pulled out, the main body 91 is positioned in front of the opening 25, and the connection of a component (not shown) paired with the connector 81a is hindered. Therefore, as shown in FIG. 7B, the arm portion 92 is bent in a direction away from the opening 25 in a portion where the regulation rib 93 is not provided in the arm portion 92. A portion of the arm portion 92 where the restriction rib 93 is provided has high rigidity due to the presence of the restriction rib 93 and is not easily bent.

According to the mobile phone 1 of the present embodiment, the following effects are exhibited.
In the mobile phone 1 of the present embodiment, the cap 90 has a regulation rib 93 that stands in the Y1 direction from the arm portion 92 toward the main circuit board 80 and can come into contact with the main circuit board 80. Therefore, the movement of the arm portion 92 in the Y1 direction is restricted by the restriction rib 93 provided on the arm portion 92, and rattling of the arm portion 92 in the Y1 direction can be prevented. As a result, the arm portion 92 is less likely to contact the electronic component 81 and the like mounted on the main circuit board 80, and the electronic component 81 can be mounted near the arm portion 92 on the lower surface 80b side of the main circuit board 80. Accordingly, the operation unit side body 2 can be downsized.

  In other words, since it is possible to suppress backlash when the arm portion 92 inserted and arranged inside the operation unit side body 2 slides, conventionally, contact with the arm portion due to backlash of the arm portion of the cap is prevented. Since the electronic component can be mounted in a region where the electronic component cannot be mounted in consideration, the mounting area on the lower surface 80b side of the main circuit board 80 can be increased.

  Moreover, the arm part holding | maintenance part 27 has a 3rd direction control part (27a, 27b) which controls the movement of the control rib 93 to the Z direction which is a 3rd direction. Therefore, the movement of the arm portion 92 in the Z direction is also restricted, and rattling of the arm portion 92 in the Z direction can be prevented, and the mounting area on the lower surface 80b side of the main circuit board 80 can be further increased.

  Further, the portion of the main circuit board 80 where the regulation rib 93 abuts is in the vicinity of a reference potential pattern layer (not shown). Since the reference potential pattern layer is generally provided in the vicinity of the edge of the main circuit board 80, the portion of the main circuit board 80 where the regulation rib 93 abuts is in the vicinity of the edge of the main circuit board 80 (this embodiment). , In the vicinity of the side edge of the main circuit board 80). Therefore, a reduction in the mounting area on the main circuit board 80 due to the presence of the regulating rib 93 can be suppressed as much as possible.

  The restriction rib 93 extends from the main body portion 91, but is shorter than the length of the arm portion 92, and therefore does not reach the distal end portion of the arm portion 92 and is not provided in the vicinity of the distal end portion of the arm portion 92. . As described above, since the restriction rib 93 is not provided near the tip of the arm portion 92, the mounting area of the electronic component 81 on the lower surface 80b side of the main circuit board 80 can be increased accordingly. If the regulating rib 93 is provided in a certain range on the main body 91 side (that is, the base end side of the arm portion 92), the arm portion 92 can be slid by the arm portion holding portion 27.

  In addition, the arm portion 92 needs to be easily folded in the vicinity of the distal end portion of the arm portion 92 in a state where the cap 90 is pulled out, but the restriction rib 93 is not provided in the vicinity of the distal end portion of the arm portion 92. Low rigidity (easy to bend) in the vicinity of the distal end portion of the arm portion 92 can be secured, and the arm portion 92 can be easily folded in the vicinity of the distal end portion.

However, the connecting unit 4 is connected to the display unit side body 3. And the operation unit side body 2 are connected so as to be openable and closable around an opening / closing axis P, and a so-called biaxial hinge mechanism is also provided that is connected to be rotatable around a rotation axis orthogonal to the opening / closing axis P. Good.

  In addition, the electronic device of the present invention is not foldable as in the above-described embodiment, and one casing is slid in one direction from the state in which the operation section side casing 2 and the display section side casing 3 are overlapped. It may be a sliding electronic device. Alternatively, a rotary (revolver) electronic device in which one casing is rotated around an axis line along the overlapping direction of the operation unit side casing 2 and the display unit side casing 3 may be used.
