Description

  The present invention relates to a portable communication device, and more particularly to a mounting structure of the SIM card.

  In recent years, with the advancement of telecommunications technology, convenience of mobile phones, PHS (Personal Handy phone System) terminals, and the like is rapidly increasing. In one example, a card capable of mounting a SIM card (Subscriber Identity Module card) has appeared.

  The SIM card is an IC (Integrated Circuit) card used in GSM (Global System for Mobile Communications) mobile phones, and internally contains a phone number, user ID (Identi-fication), call charge, phone book, memo Information such as is described.

  Normally, communication is performed with the phone number and user ID written in the built-in memory of the mobile phone, so even if another person uses this mobile phone, the user written in the built-in memory used it. It will be. However, if the SIM card is replaced, it is used by the user registered in the SIM card, and when the person's mobile phone breaks down or the battery runs out, borrow another person's mobile phone and If the SIM card is replaced, it can be temporarily used as a mobile phone of the person.

  However, when replacing the SIM card, the SIM card may be damaged if the order of removing the SIM card after removing the battery is not followed.

Therefore, for example, Patent Documents 1 to 3 are configured such that the SIM card is placed under the battery so that the order in which the SIM card is removed after the battery is removed can always be observed. With this configuration, the SIM card is prevented from being destroyed.

  However, when a SIM card is placed under the battery as in a conventional mobile phone, if the SIM card is mounted in the SIM card mounting recess on the bottom surface of the battery storing recess, it is difficult for a finger to enter when the SIM card is removed. , Desorption will be bothersome. For this reason, a taper is provided on one side surface of the SIM card mounting recess so as to be detachable while sliding.

  However, the mobile phone may be inadvertently dropped on the ground while being carried, and at this time, it may be difficult to imagine normally. That is, the SIM card moves along the taper due to the fall, and the position shifts. As a result, a situation occurs in which the SIM card is detached and damaged before the battery even though the battery is not detached.

  In view of the above problems, the present invention is to provide a structure of a mobile communication device in which the SIM card is not easily damaged even if the mobile communication device is inadvertently dropped and the SIM card is displaced.

In order to achieve the above object, the structure of the mobile communication device of the present invention is directed to a mobile communication device in which a SIM card can be mounted,
A battery housing recess for housing the battery;
A SIM card storage recess provided on the bottom surface of the battery storage recess;
A locking claw having elasticity for fixing the SIM card,
It arrange | positions at the one side of the said SIM card accommodation recessed part so that the said latching claw may support the one end side of the said SIM card.

  Thereby, the SIM card is inserted and removed after the battery is removed. Also, the SIM card can be easily inserted and fixed. In addition, the SIM card storage recess is provided in the battery storage recess, and a new fixing frame is not required.

  In the second invention, the locking claw is formed integrally with the bottom surface of the battery housing recess.

  Thereby, it becomes unnecessary to prepare a locking claw as a part, and there is no cost increase.

  In a third aspect of the invention, the locking claw has a tongue-like shape by cutting out three sides of the meat, and only the base end side is supported by the bottom surface of the battery housing recess to be in a cantilever state. Yes.

  Thereby, a latching claw is provided with moderate elasticity and the insertion property of a SIM card improves.

  In 4th invention, the front-end | tip of the said latching claw has the thickness direction inclined surface which inclines in the thickness direction.

  As a result, when the SIM card is dropped, the SIM card slides along the slope, and it is possible to control whether the SIM card slides upward or downward.

  In 5th invention, the thickness direction inclined surface of the front-end | tip of the said latching claw has a slope which the back side retracts | sucks rather than the surface side in the thickness direction of this latching claw.

  Thereby, at the time of dropping, the SIM card comes to slide below the locking claw.

  In the sixth invention, a gap is formed between one end of the SIM card and the tip of the locking claw.

  As a result, the SIM card can be inserted more easily than when there is no gap.

  In the seventh invention, a SIM card contact portion perpendicular to the bottom of the SIM card storage recess is formed on the back surface side of the inclined surface in the thickness direction at the tip of the locking claw, and the SIM card contact The configuration prevents the SIM card from being displaced.

  As a result, even if a gap is formed between the locking claw and the SIM card, the SIM card abuts on the SIM card abutting portion, so that the displacement of the SIM card is restricted when the mobile communication device falls.

  In the eighth invention, reinforcing ribs are formed around the back surface of the locking claw.

  Thereby, even if the thickness of the locking claw is thin, the strength can be increased.

  In a ninth aspect of the invention, the SIM card storage recess has a recess-side inclined surface on one side surface.

  Thereby, mounting | wearing becomes easy by sliding a SIM card | curd on a recessed part side inclined surface, and mounting | wearing.

  In a tenth aspect of the invention, the upper surface of the locking claw has a surface-side inclined surface that is inclined toward the tip in the vicinity of the tip.

  This makes it easy to remove the SIM card by sliding the upper surface of the locking claw.

  In an eleventh aspect of the invention, the gradient of the surface-side inclined surface is smaller than the gradient of the concave-side inclined surface.

  As a result, when the SIM card is attached / detached while pressing the locking claw with a finger, the SIM card slides along the recess-side inclined surface, and is easy to be removed because it is not caught by the locking claw.

  In the twelfth invention, pressing concave portions for pressing the locking claws are formed on both sides of the locking claws.

  Thereby, it becomes easy to slide the locking claw to the depressions for pressing on both sides.

  In the thirteenth invention, a through hole is formed in substantially half of the SIM card housing recess opposite to the one side surface, and the SIM card holder mounted on the substrate is exposed from the through hole. .

  As a result, the SIM card can be mounted without opening and closing the housing and the number of components is reduced.

  In a fourteenth aspect, the mobile communication device is a mobile phone.

  Even if the mobile communication device is inadvertently dropped, since the SIM card connection is unlikely to stop before the battery is removed, the SIM card is difficult to break.

  Also, the SIM card can be easily inserted and removed by the concave-side inclined surface of the SIM card housing recess and the front-side inclined surface of the locking claw.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A battery cover 14, a camera unit 15, and an antenna terminal cover 16 are provided on the back surface of the second housing 3. Further, a rectangular battery housing recess 29 for housing the battery 41 (shown in FIG. 5) with the battery cover 14 removed is formed. A connection terminal portion 17 for connecting an earphone microphone terminal is provided on the right side surface of the second housing 3, and a card insertion portion 18 for inserting a card is provided on the left side surface of the second housing 3. On the lower side surface of the second housing 3, charging terminal insertion portions 19 for charging the battery 41 stored in the battery storage recess 29 are provided.

  As shown in FIG. 3, the SIM card 23 has a substantially rectangular plate shape in which only one corner is chamfered, and three sides are fixed by a SIM card holder 22 (shown in detail in FIG. 9). One side is not shown), and one side is fixed by a locking claw 20. A plurality of SIM card contacts 53 are provided on the back side of the SIM card 23.

  As shown in FIG. 4, the SIM card that is recessed in a substantially rectangular shape so as to correspond to the shape of the SIM card 23 at the portion where the SIM card 23 of the second housing 3 is disposed on the bottom surface of the battery housing recess 29. A storage recess 26 is formed. A locking claw 20 is integrally formed on one side surface (the hinge portion 4 side) of the SIM card housing recess 26. Further, on both sides of the locking claw 20, a depression 21 for pressing that is oval in a plan view and recessed from the periphery is formed.

  As shown in FIGS. 7 and 8, the locking claw 20 is thin and is integrally formed simultaneously with the second housing 3. The latching claw 20 has a tongue-like shape by cutting out the meat on three sides, and only the hinge portion 4 side is supported by the bottom surface of the battery housing recess 29 and is in a cantilever state. Thereby, the latching claw 20 has moderate elasticity. On the surface side of the locking claw 20, a surface-side inclined surface 20a that is slightly inclined toward the bottom 26a side of the SIM card storage recess 26 is formed. On the hinge part 4 side of the SIM card storage recess 26, a recess-side inclined surface 27 that is inclined toward the opposite side of the hinge part 4 toward the bottom 26a side is formed. The inclination of the surface-side inclined surface 20 a is extremely smaller than that of the concave-side inclined surface 27.

  A SIM card contact portion 20c perpendicular to the bottom portion 26a is formed on the back side of the front end of the locking claw 20. On the surface side of the SIM card abutting portion 20c, a thickness direction inclined surface 20b that is inclined toward the front end side in a direction away from the SIM card abutting portion 20c is formed. That is, the thickness direction inclined surface 20 b is a slope in which the back surface side is retracted more than the front surface side in the thickness direction of the locking claw 20. While the SIM card 23 is attached, the SIM card 23 is in contact with the inclined surface 20b in the thickness direction and the SIM card abutting portion 20c with the end portion on the hinge portion 4 side of the SIM card 23. Movement is regulated. The retaining claws 20 are provided with reinforcing ribs 20d on the outer periphery of the back surface of the three sides so as to increase the strength so that the locking claws 20 are not broken by the movement of the SIM card 23 in the case of dropping or the like.

  As shown in FIGS. 4 to 6, approximately half of the SIM card storage recess 26 on the hinge portion 4 side is formed integrally with the bottom surface of the battery storage recess 29, and the other half is a rectangular through hole 28. Yes. From the through hole 28, the SIM card holder 22 soldered to the main board 51 is exposed. The protruding amount of the SIM card holder 22 is the same height as the bottom surface of the battery housing recess 29 with the SIM card 23 mounted, and the SIM card housing recess 26 is used to place the thin rectangular parallelepiped battery 41 on the battery housing recess 29. The depth is the same. The battery 41 is connected to the connection terminal 25.

  FIG. 9 is a perspective view of the SIM card holder 22. The SIM card holder 22 has a housing 56 made of a resin molded product, and this housing 56 has a housing side abutting portion 55 with which one end of the SIM card 23 opposite to the hinge portion 4 abuts. ing. Thus, the housing side contact portion 55 determines the position when the SIM card 23 is inserted. Locking arms 54 made of sheet metal are provided on both sides, and the locking arms 54 determine the positions of the SIM card 23 in the left-right direction and the front-back direction. A holder contact 24 is formed inside the housing 56 so as to correspond to the SIM card contact 53 of the SIM card 23, and the approximate center of the holder contact 24 slightly protrudes from the bottom surface of the housing 56 and has an elastic force. ing. Due to this protrusion, the SIM card 23 is configured to be easily connected to the SIM card contact 53.

  With this configuration, the SIM card 23 is fixed by the two locking arms 54 of the SIM card holder 22 and the housing-side contact portion 55 of the housing 56. Since the locking claw 20 is disposed on the hinge part 4 side of the SIM card 23, the SIM card 23 is prevented from moving to the hinge part 4 side. In order to facilitate the insertion of the SIM card 23, a small gap 30 (shown in FIG. 6) is formed between the SIM card 23 and the locking claw 20. Further, the holder contact 24 is long so that the connection between the holder contact 24 and the SIM card contact 53 is not removed even if the SIM card 23 moves until the gap 30 contacts the SIM card contact portion 20c. Yes.

-Action-
First, a method for detaching the SIM card 23 according to the present embodiment will be described.

  When the SIM card 23 is mounted from the state of FIG. 4, the SIM card 23 is placed on the top of the locking claw 20 and one end opposite to the hinge portion 4 is slid on the bottom 26 a of the SIM card storage recess 26. Then, it is slid so as to be hidden in the SIM card holder 22, and one end of the SIM card 23 opposite to the hinge part 4 is inserted until it comes into contact with the housing side contact part 55.

  On the contrary, in order to take out the SIM card 23, the SIM card 23 is slid so as to pass over the locking claw 20 while pressing the locking claw 20 with a finger. When pressing the locking claw 20 with a finger, the pressing claw 20 can be easily pressed because the pressing recess 21 is almost the size of a finger.

  Further, since the slope of the surface-side inclined surface 20a provided on the locking claw 20 is smaller than that of the recessed-side inclined surface 27, when the SIM card 23 is slid and removed, if the locking claw 20 is pressed, the SIM card 23 contacts the recess-side inclined surface 27 before contacting the surface-side inclined surface 20a, and is pulled out from the SIM card storage recess 26 along the recess-side inclined surface 27, so that the tip of the locking claw 20 is at the SIM card 23. It is hard to get caught in.

  Further, while the SIM card 23 is mounted, a gap 30 is formed between the end of the SIM card 23 on the hinge part 4 side and the tip of the locking claw 20. When the direction inclined surface 20b and the SIM card abutting portion 20c abut on the SIM card 23, the movement range is restricted.

  Next, a drop test of the mobile phone 1 will be described.

  FIG. 10 is an enlarged cross-sectional view of the SIM card storage recess 26 and its periphery when a drop test is performed. Even if the SIM card 23 moves to the hinge part 4 side due to the impact of the drop and comes into contact with the SIM card contact part 20c, the SIM card contact 53 of the SIM card 23 and the holder contact 24 are kept connected.

  When the SIM card 23 moves due to dropping or the like, the SIM card 23 first comes into contact with the thickness direction inclined surface 20b, and the locking claw 20 tends to be lifted upward by the thickness direction inclined surface 20b. Then, it hits the SIM card contact portion 20c and stops.

  It is to be noted that when the thickness direction inclined surface 20b has a reverse gradient, the SIM card 23 moves greatly on the locking claw 20 and the connection between the SIM card contact 53 and the holder contact 24 is released. It turns out.

-Effect of the embodiment-
Therefore, according to the mobile phone 1 according to the present embodiment, even if the mobile phone 1 is inadvertently dropped, the SIM card 23 is not easily disconnected before the battery 41 is removed, so the SIM card 23 is destroyed. It is hard to do.

  Further, the SIM card 23 can be easily inserted and removed by the concave-side inclined surface 27 of the SIM card housing concave portion 26 and the thickness-direction inclined surface 20b of the locking claw 20.

  As described above, the present invention is useful for a portable communication device in which a SIM card can be mounted.
