  The present invention relates to an electronic device such as a mobile phone. Specifically, the present invention relates to an electronic device including a cover member that closes an opening provided in a housing.

2. Description of the Related Art In recent years, with the advancement of functions in mobile phones as electronic devices, various connectors (cable connectors for connecting to external devices, cards that can be attached with external memory, etc.) can be mounted inside the casings of mobile phones. Connectors, earphone connectors, etc.) are provided. Further, internal components such as a circuit board and a shield case are housed inside the housing. Electronic components such as connectors are mounted on a circuit board.
The connector is disposed to face an opening formed in the housing, and is exposed to the outside of the housing through the opening. The opening is closed by a cap as a cover member.

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

  As a mobile phone provided with such an arm-attached cap, for example, in Patent Document 1, a distal end portion of the arm portion is provided with a drop prevention portion that protrudes outward in the width direction, and the width direction on the distal end side of the arm portion is provided. A mobile phone including an arm cap with an opening at the center is disclosed.

The cap with an arm portion disclosed in Patent Document 1 is attached to the housing by inserting the arm portion into the inside of the housing from the arm portion insertion opening provided in the housing. Here, the width of the arm insertion opening is configured to be larger than the width of the arm and smaller than the width of the tip of the arm. And when inserting an arm part, the front-end | tip part of an arm part is pressed on an arm part insertion opening. Then, since an opening is formed on the distal end side of the arm portion, the distal end portion of the arm portion bends inward as the opening is deformed. Thereby, the front-end | tip part of an arm part passes the arm part insertion opening, and is inserted in the inside of a housing | casing. After passing through the arm insertion opening, the shape of the bent tip is recovered. Since the width of the tip of the arm is larger than the width of the arm insertion opening, the arm inserted through the inside of the housing does not come out of the housing.

The “X2 direction” is a direction opposite to the X1 direction. The X1 direction and the X2 direction are collectively referred to as the “X direction”.

The “Y1 direction” is a direction in which the locking rib 27 protrudes at the second opening 26. The “Y2 direction” is a direction opposite to the Y1 direction. The Y1 direction and the Y2 direction are collectively referred to as the “Y direction”. The Y direction in the present embodiment is the short side direction of the second opening 26.

As shown in FIGS. 8 and 9, the first side surface 931 that is one long side surface of the thick portion 93 is a smooth surface, and the second side surface 932 that is the other long side surface is the second side surface. A thin portion 94 is formed in which 932 has a predetermined width and is recessed in the Y2 direction to reduce the thickness of the thick portion 93. In other words, the thin portion 94 is formed by thinning the thick portion 93 in a direction substantially perpendicular to the insertion direction (X1 direction) of the arm portion 92 into the second opening 26.
The thin portion 94 is formed at the center of the second side surface 932 in the direction substantially perpendicular to the insertion direction (X1 direction) of the arm 92 into the second opening 26, from the distal end 92b side of the arm portion 92 to the proximal end 92a side. Formed towards.

As shown in FIGS. 5 and 7, the recess depth a <b> 1 of the thin portion 94, which is a thickness by which the thin portion 94 thins the thick portion 93, is substantially equal to the protruding length a <b> 2 of the locking rib 27. .
Further, the arm portion thickness b (see FIG. 6) closer to the base end 92a than the thick portion 93 is provided with the arm portion thickness d1 (see FIG. 7) in the thin portion 94 and the locking rib 27. It is thinner than the length d2 (see FIG. 5) in the short side direction of the second opening 26 in the portion.

  The thickness c1 of the arm portion 92 in the thick portion 93 is substantially equal to the length c2 in the short side direction of the second opening portion 26, and the recess depth a1 of the thin portion 94 is the protruding length of the locking rib 27. Therefore, the thickness d1 of the arm portion in the thin portion 94 is substantially equal to the length d2 in the short side direction of the second opening portion 26 in the portion where the locking rib 27 is provided.

  In the present embodiment, the thick part 93 is suitably bent and inserted into the operation unit side body 2, and the thick part 93 inserted into the operation unit side body 2 is difficult to come out. From the viewpoint, the protrusion length a2 of the locking rib 27 and the recess depth a1 of the thin portion 94 are each preferably 0.1 to 0.3 mm.

The arm portion 92 can be elastically deformed with the first groove 95 and the second groove 96 as base points.

Next, a procedure for attaching the cap 90 to the operation unit side body 2 will be described with reference to FIGS. 10 to 12.
FIG. 10 is a partially enlarged cross-sectional view of the operation unit side body 2 showing a state before the cap 90 is attached to the rear case 22. FIG. 11 is a partial enlarged cross-sectional view of the operation unit side body 2 showing a state in which the first opening 25 and the second opening 26 are closed by the main body 91 of the cap 90. 12 is a partially enlarged cross-sectional view of the operation unit side body 2 showing a state in which the cap 90 in the state shown in FIG. 11 is moved in the X2 direction.

In the present embodiment, the arm 92 is inserted into the second opening 26 from the tip 92b side.
In this case, first, the arm portion 92 is aligned with the second opening portion 26 in a state where the first side surface 931 of the thick portion 93 is opposed to the locking rib 27 provided in the second opening portion 26 (FIG. 10).

  Next, when the arm portion 92 is pushed in the X1 direction in this state, the locking rib 27 presses the first side surface 931 of the thick portion 93 in the Y1 direction. Then, both ends in the width direction of the thick portion 93 are deformed and bent (not shown) in the Y2 direction side with the thin portion 94 formed on the second side surface 932 as a base point, and the thick portion 93 has the second opening portion. 26 (see FIG. 11).

The thick part 93 that has passed through the second opening 26 in a bent state is restored to its original shape inside the operation unit side body 2.
The base end 92a side of the thick portion 93 is formed such that the thickness b of the arm portion 92 is thinner than the length d2 in the short side direction of the second opening 26 in the portion where the locking rib 27 is provided. Yes. Thereby, the base end 92a side rather than the thick part 93 in the arm part 92 becomes slidable in the X direction. In this manner, the cap 90 is held by the operation unit side body 2 in a state where the arm portion 92 is slidable in the X direction.

  When the arm portion 92 is slid in the X2 direction after the cap 90 is attached to the operation unit side body 2, the thickness c1 of the thick portion 93 is the second opening at the portion where the locking rib 27 is provided. The portion 26 is configured to be longer than the length d2 in the short side direction. Therefore, the movement of the thick portion 93 in the X2 direction is restricted by the locking rib 27 (see FIG. 12). As a result, the thick portion 93 does not easily pass through the second opening 26 in the X2 direction, and thus the cap 90 is unlikely to come off from the operation unit side body 2.

  According to the present embodiment, the second opening 26 through which the arm portion 92 is inserted is provided with the locking rib 27 protruding to the arm portion 92 side, and the thick portion 93 is provided on the distal end side of the arm portion 92. A second side surface 932 which is a side surface opposite to the side surface facing the locking rib 27 in the thick portion 93 is provided. Thus, when the thick portion 93 is pressed against the second opening, the locking rib 27 presses the first side surface 931 in the Y1 direction, and the thick portion 94 starts from the thin portion 94 provided on the second side surface 932. 93 is bent, so that the thick part 93 can pass through the second opening 26. In addition, the thick portion 93 that has passed through the second opening 26 in a bent state is restored to its original shape inside the operation unit side body 2.

  Here, the first side surface 931 facing the locking rib 27 is a smooth surface, and the thin portion 94 is provided on the second side surface 932 located on the opposite side of the first side surface 931. That is, the convex locking rib 27 and the second side surface 932 on which the concave thin portion 94 is formed are not opposed to each other. As a result, the thick portion 93 inserted in the operation unit side body 2 is unlikely to pass through the second opening 26 in the X2 direction, so that the cap 90 is unlikely to fall out of the operation unit side case 2.

  As described above, according to the present embodiment, the mobile phone 1 including the cap 90 that is easy to insert and difficult to remove can be provided by using the arm portion 92 that is substantially the same shape as the second opening portion 26. That is, without increasing the size of the arm portion 92, it is possible to provide the mobile phone 1 including the cap 90 that is excellent in insertability into the operation unit side body 2 and that is difficult to come off from the operation unit side body 2.

  In addition, the outer shape of the thick portion 93 is substantially equal to the outer shape of the second opening 26. Thereby, the movement in the X2 direction of the thick portion 93 inserted into the operation unit side body 2 is reliably restricted by the locking rib 27. Therefore, since the thick part 93 does not easily pass through the second opening 26 in the X2 direction, the cap 90 is unlikely to come off from the operation unit side body 2.

  In addition, the locking rib 27 is provided at the central portion in the longitudinal direction of the rectangular second opening 26, and the thin portion 94 is formed at the central portion in the width direction of the arm portion 92. As a result, when the locking rib 27 presses the thick portion 93 in the Y1 direction, both end portions of the thick portion 93 are easily deformed in the Y2 direction. It becomes easy to insert the inside of the.

  In addition, since the protruding length a2 of the locking rib 27 is substantially equal to the recess depth a1 of the thin portion 94, the locking rib 27 presses the thick portion 93 to bend the thick portion 93. The thick portion 93 is easily deformed into a shape that can pass through the second opening 26. Therefore, the arm portion 92 can be easily inserted into the operation unit side body 2.

As mentioned above, although one Embodiment of this invention was described, this invention is not restrict | limited to embodiment mentioned above, It can change suitably.
For example, in the present embodiment, the first opening 25 and the second opening 26 are provided on the back surface 2b of the operation unit side body 2, but not limited thereto, the first opening and the second opening are You may provide in the side surface of the operation part side housing | casing. Moreover, although the main-body part 91 closed the 2nd opening part 26, this invention is not limited to such a case, As long as the main-body part 91 covers the 2nd opening part 26, it is. Good.

  In the present embodiment, the present invention is applied to the operation unit side body 2, but is not limited thereto, and may be applied to the display unit side body 3, for example.
