As shown in FIGS. 2 and 3, in the connection portion 26, a communication hole 27 that communicates the inside and outside of the case 21 constituting the housing 20 is provided in the front vertical wall 241 of the case 21. The communication hole 27 has a rectangular opening 271 exposed on the front surface of the front vertical wall 241 and a communication hole main body 272 having, for example, an oval shape extending continuously to the inside of the case 21 following the opening 271. A lid member 30, which will be described in detail later, is detachably attached to the communication hole 27.
An external connector 28 for connecting an external device is exposed inside the communication hole main body 272. Further, a groove portion 273 (see FIG. 6) for inserting the hinge portion 31 (see FIGS. 4A and 4B) of the lid member 30 is inserted in front of the communication hole main body 272 so as to be continuous with the opening portion 271. Is provided along the front vertical wall 241 to the right side surface (side vertical wall 242).

4A and 4B, the lid member 30 attached to the communication hole 27 includes a rectangular plate-like lid body 32 that covers the opening 271 of the front vertical wall 241 and the longitudinal direction of the lid body 32. Has a tongue-like hinge portion 31 protruding along the axis.
The lid main body 32 is formed so that the outer surface 321 is flush with the outer surface of the front vertical wall 241 in the mounted state. Further, the inner surface 322 of the lid body 32 is provided with an insertion portion 33 that is inserted into the communication hole 27 so as to protrude.

As shown in FIG. 5, the insertion portion 33 has an oval insertion portion main body 34 corresponding to the shape of the communication hole main body 272 and serving as a water stop portion on the lid main body 32 side (that is, the front side). In addition, a pair of locking portions 35 </ b> A and 35 </ b> B are provided on the distal end side (that is, the rear side) of the insertion portion 33 at positions facing each other at both longitudinal ends of the insertion portion main body 34. The locking portion 35 </ b> A is provided on the side far from the hinge portion 31, and the locking portion 35 </ b> B is provided on the side close to the hinge portion 31.
In addition, when a pair of latching | locking part 35A, 35B is named generically, it displays with the "locking part 35".
Here, since the locking portion 35B has the same configuration as the conventional one (see FIGS. 9A and 9B), the following description will mainly focus on the locking portion 35A having the features of the present invention. explain.

As shown in FIGS. 4 and 5, the first outer surface 341 that is the outer peripheral surface of the insertion portion main body 34 is formed with a recess 342 over the entire circumference, and the recess 342 has an O-ring that is a ring-shaped elastic member. 36 is attached.
4A and 4B, the O-ring 36 is not attached and only the lid member 30 is shown.

The O-ring 36 is formed in a ring shape from an elastic material such as rubber, and the overall length is slightly shorter than the overall length of the recess 342. Therefore, the O-ring 36 is attached to the recess 342 in a stretched state. A portion of the attached O-ring 36 protrudes outward from the recess 342, and the first inner side surface 275 that continues from the outer opening edge 274 of the communication hole 27 in a state where the lid member 30 is attached to the communication hole 27. Crush on. Thereby, the water stop in the communication hole 27 is performed.
In this embodiment, an example in which an O-ring is used as a ring-shaped elastic member will be described. However, the “ring shape” here is a discontinuous ring shape having a notch part. It also includes C-rings.

A claw portion 352 is provided on the second outer surface 351 which is the outer surface of the locking portion 35A. When the lid member 30 is attached to the communication hole 27, the claw portion 352 is located on the inner side of the second inner side surface 276 located on the inner side of the case 21 (upper side in FIG. 5) than the first inner side surface 275 of the communication hole 27. Engages with the opening edge 277.
As a result, the lid member 30 is locked in a state of being attached to the communication hole 27.

Further, the protrusion direction tip of the claw portion 352 is set so as not to reach the first inner side surface 275 of the communication hole 27 in the mounted state.
For this reason, when the insertion portion 33 is inserted into the communication hole 27, the tip of the claw portion 352 does not contact the first inner side surface 275 of the communication hole 27.

Further, the second inner side surface 276 of the communication hole 27 protrudes toward the insertion portion 33 of the lid member 30 from the first inner side surface 275. Here, the second inner side surface 276 is inclined toward the center side of the communication hole 27 from the inner end (upper end in FIG. 5) of the first inner side surface 275 toward the inner side.
Therefore, when the claw portion 352 is disposed outside the second inner side surface 276 and the insertion portion 33 is inserted into the communication hole 27 and the claw portion 352 exceeds the second inner side surface 276, the inner opening edge portion 277 is formed. It is locked to.

Next, the attaching / detaching operation of the lid member 30 to the communication hole 27 will be described.
6, first, the lid member 30 is inclined with respect to the front vertical wall 241 of the case 21 (see arrow A in FIG. 6), and the hinge portion 31 of the lid member 30 is connected to the communication hole 27. Is inserted into the groove 273 from the opening 271 (see arrow B in FIG. 6).
Next, the lid main body 32 is rotated toward the communication hole 27 with the hinge 31 as a rotation center (see arrow C in FIG. 6), and the insertion portion 33 is inserted into the communication hole 27. Thereby, the lid body 32 is inserted into the opening 271 of the communication hole 27, and the outer surface 321 of the lid body 32 is flush with the outer surface of the front vertical wall 241 of the case 21.

A claw 352 provided at the tip of the locking portion 35 of the insertion portion 33 passes through the inner opening edge 277 of the communication hole 27 and locks the inner opening edge 277. Accordingly, the O-ring 36 provided around the insertion portion 33 is sandwiched between the insertion portion 33 and the first inner side surface 275 of the communication hole 27 to waterproof the communication hole 27.
At this time, the first inner side surface 275 of the communication hole 27 into which the locking portion 35A is inserted is outside the turning radius of the first outer side surface and the second outer side surface of the lid member 30, that is, the side far from the hinge portion 31. Is provided. For this reason, the claw portion 352 does not contact the first inner side surface 275 and the second inner side surface 276 of the communication hole 27 except when it finally gets over the second inner side surface 276 of the communication hole 27.

Further, the locking portion 35 </ b> B close to the hinge portion 31 draws a turning locus that is pressed against the first inner side surface 275 and the second inner side surface 276 from the inside of the communication hole 27, and thus does not rub.
In addition, when removing the cover member 30 from the communication hole 27, the process mentioned above is performed reversely.

  As described above, according to the portable terminal 10 of the embodiment according to the present invention described above, the lid member 30 is provided in the communication hole 27 that communicates the inside and the outside of the housing 20, and the communication hole 27 is formed outside the housing 20. Close from. The lid member 30 includes a lid body 32 that covers the communication hole 27, an insertion portion 33 that is inserted into the communication hole 27, and an O-ring 36 that is attached to the outer peripheral surface of the insertion portion 33. The O-ring 36 is attached to the first outer surface 341 on the lid body 32 side on the outer peripheral surface of the insertion portion 33. A claw portion 352 is formed at the distal end portion of the second outer surface 351 on the distal end side on the outer peripheral surface of the insertion portion 33.

  And since the 2nd outer side surface 351 of the insertion part 33 is located in the center side of the communicating hole 27 with respect to the 1st inner side surface 275, it does not contact the 1st inner side surface 275. In addition, since the protrusion direction tip protruding from the second outer surface 351 in the claw portion 352 is provided at a position that does not reach the first inner surface 275 of the communication hole 27, the claw portion is also attached when the lid member 30 is attached. 352 does not contact the first inner surface 275 of the communication hole 27. Further, since the second inner side surface 276 protrudes toward the insertion portion 33 rather than the first inner side surface 275, the claw portion 352 that does not contact the first inner side surface 275 is locked by the second inner side surface 276.

  Accordingly, when the lid member 30 is attached to and detached from the communication hole 27, the claw portion 352 of the lid member 30 can be prevented from coming into contact with the inner side surface that is the water stop surface of the communication hole 27, so that the water stop surface is prevented from being scraped. And the water stop performance in the communication hole 27 can be maintained. Further, since the claw portion 352 can avoid contact with the inner surface of the communication hole 27, it can prevent abrasion due to wear and is locked by the second inner surface 276 protruding toward the insertion portion 33. The lid member 30 can be securely attached.

  Further, since the second inner side surface 276 of the communication hole 27 is inclined with respect to the first inner side surface 275, when the lid member 30 is attached to the communication hole 27, the claw portion 352 of the insertion portion 33 is connected to the communication hole 27. After elastically deforming inside, the claw portion 352 can be smoothly locked without being caught.

  Further, the lid member 30 has a lid body 32 connected to the housing 20 via a hinge portion 31, and the insertion portion 33 communicates with the housing 20 while rotating around the hinge portion 31. Since it is inserted into the hole 27, the insertion portion 33 can be reliably inserted into the communication hole 27. Further, the first inner side surface 275 of the communication hole 27 is provided outside the turning radius of the first outer side surface and the second outer side surface of the lid member 30 with the hinge portion 31 as the center. Do not touch. For this reason, deterioration of the 1st outer side surface 341, the 2nd outer side surface 351, and the 1st inner side surface 275 can be prevented, and water stop performance can be maintained.

  When the second outer surface 351 of the locking portion 35A is farther from the first inner side surface 275 and the second inner side surface 276 of the communication hole 27 than the first outer surface 341, that is, the locking portion. When the second outer surface 351 located on the distal side in the insertion direction with respect to the first outer surface 341 in 35A is located on the center side of the communication hole 27 with respect to the first outer surface 341, the insertion portion 33 is inserted into the communication hole 27. In addition, the claw portion 352 provided on the second outer surface 351 is less likely to rub against the first inner surface 275 and the second inner surface 276 of the communication hole 27, and is more effective for preventing the water stop surface and the claw portion from being scraped. become.

The portable terminal of the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made.
For example, in the above-described embodiment, the configuration of the present invention has been illustrated for the case where the configuration of the present invention is applied only to the locking portion 35 </ b> A far from the hinge portion 31, but also to the locking portion 35 </ b> B closer to the hinge portion 31. Applicable.

Further, in the above-described embodiment, the case where the second inner side surface 276 of the communication hole 27 is linearly inclined with respect to the first inner side surface 275 is illustrated, but the present invention is not limited thereto.
That is, as shown in FIG. 7A, the second inner side surface 276B can be provided so as to protrude toward the communication hole 27 in a curved shape with respect to the first inner side surface 275.
Further, as shown in FIG. 7B, the second inner side surface 276C can be provided so as to protrude toward the communication hole 27 stepwise with respect to the first inner side surface 275.

  As described above, the portable terminal according to the present invention can prevent the claw portion of the lid member from coming into contact with the inner surface that is the water stop surface of the communication hole when the cover member is attached to and detached from the communication hole. It is possible to keep the water stop performance in the communication hole. Further, since the claw portion of the lid member can avoid contacting the inner surface of the communication hole, the claw portion can be prevented from being scraped and is locked by the second inner surface protruding toward the insertion portion.
