The cover body 6 can be put away from in front of an opening part 4 formed on the case 2 corresponding to the arrangement position of an external connection terminal 3 without bending the fall-prevention belt 7 large, so that the cover body 6 and fall-prevention belt 7 are not obstacles and a raw material of the fall-prevention belt 7 is suppressed from deteriorating.

Description

  The present invention is provided on one surface of the housing for connecting the connector cover to the housing and the connector cover covering the opening formed in the housing of the portable terminal corresponding to the arrangement position of the external connection terminal. The present invention relates to an improvement in a connector cover structure constituted by a mounting portion.

  Various mobile terminals such as PHS, mobile phones, smartphones, and the like are provided with external connection terminals for connecting to external connection objects at the time of input / output of information or charging using wired LAN communication. In order to realize the dustproof function and the waterproof function, a connector cover for covering the opening formed in the housing of the mobile terminal corresponding to the position of the external connection terminal is required.

  This type of connector cover is generally composed of a cover body that fits into an opening of a housing so as to be able to open and close the opening, and a flexible belt-like body that extends outward from the outer periphery of the cover body. And a drop-off prevention band.

  The drop-off prevention band is intended to prevent the cover body from being accidentally dropped or lost, and may be constructed using a mechanical hinge structure. From the viewpoints of miniaturization and manufacturing cost, a flexible belt-like body is employed exclusively as disclosed in Patent Document 1 and the like.

In addition, there is a configuration in which a drop-off prevention band made of a flexible belt-like body is formed longer, a stopper is provided at the base thereof, and the casing can be freely moved into and out of a certain limit.
When such a configuration is applied, after the fitting between the cover main body and the opening is released, the drop-off prevention band is pulled out of the casing, and the cover main body is bent by the long span to open the cover main body. Therefore, there is an advantage that deterioration of the material of the drop-off prevention band due to extreme bending can be suppressed.

  However, in any case, the fall prevention band is bent and retracted from the front of the opening, and when the hand is released from the fall prevention band or the cover body, the cover body is restored by the elastic return force of the drop prevention band. When the external connection object such as a plug or cradle is connected to the external connection terminal of the portable terminal by returning to the position covering the opening formed in the housing corresponding to the position, that is, the position of the external connection terminal In addition, the cover main body and the drop-off prevention band interfere with each other and cause an inconvenience.

  Also, if the cover body and the fall prevention band are bent so that they do not interfere with the object to be connected and the cover body is opened repeatedly, the material of the fall prevention band may deteriorate and break. is there.

  In particular, when the object to be connected is a large object such as a cradle, even if the cover body is flipped 180 ° and opened, the space between the surface of the housing in which the opening is formed and the cradle. The cover main body and the drop-off prevention band are sandwiched, and the cover main body and the drop-off prevention band are extremely disturbing.

  Like the cover disclosed in Patent Document 2, it has been proposed to hold the cover in an open position by fitting the support portion and the cover in an uneven state with the hinge portion made of an elastic body bent, Since the hinge portion is formed at the center inside the cover, the opening angle of the cover is limited to about 90 ° due to the interference between the support portion and the cover. In other words, since the cover cannot be reversed 180 ° and opened, interference with the cover is inevitable for connection with a large object such as a cradle.

  Alternatively, if the hook structure disclosed in Patent Document 3 is diverted, it is possible to make the cover body and the fall-off prevention band integrally removable from the housing. If you remove it, it will be a problem.

In addition, a charging cradle is provided by disposing external connection terminals for realizing frequently used charging functions and the like so as to be exposed to the outside of the housing independently of external connection terminals such as USB. However, there is an inconvenience that the manufacturing cost of the device increases as the number of external connection terminals increases.
In addition, such an irregular solution has a disadvantage that it cannot be used for an external connection terminal used for purposes other than charging, for example, an external connection terminal such as a USB whose dimensions and arrangement standards are determined.

JP 2003-283157 A (paragraph 0020, FIGS. 1 to 2 and 5) JP 2008-235069 A (paragraph 0016-paragraph 0019, FIGS. 1-4) Japanese Patent Laying-Open No. 2006-115163 (paragraph 0034, FIG. 4)

  Therefore, the object of the present invention is to prevent the cover body and the drop-off prevention band from getting in the way when connecting an external connection object to the external connection terminal of the mobile terminal, and also suppress the deterioration of the material of the drop-off prevention band. The object is to provide a connector cover structure.

The connector cover structure of the present invention includes a connector cover that covers an opening formed in the casing of the mobile terminal corresponding to the position of the external connection terminal, and a connector cover for connecting the connector cover to the casing. A connector cover structure constituted by a mounting portion provided on one surface, in order to achieve the object,
The connector cover includes a cover body that fits into the opening and covers the opening so as to be openable and closable, and a flexible belt-like body that extends outward from the outer periphery of the cover body. And a drop-off prevention band integrally formed with a fastening portion for connecting to the mounting portion on the part,
The attachment portion and the fastening portion are configured to allow a change in the rotation posture of the drop-off prevention band and the cover body around the normal line of the one surface at the position where the attachment portion is disposed. The configuration is as follows.

In the connector cover structure of the present invention, the fastening portion formed at the distal end portion of the drop-off prevention band made of a flexible belt-like body extending outward from the outer peripheral portion of the cover body is provided on one surface of the casing of the mobile terminal. By connecting to the mounting part provided on the cover, the fall prevention band with the mounting part as the center of rotation and the rotation posture change of the cover body are allowed. By changing the rotation posture of the belt, the opening can be completely opened by retracting the cover body from the front of the opening formed in the housing corresponding to the position of the external connection terminal.
In addition, after the cover body is opened, there is no possibility that the cover body may return to the position where the opening is inadvertently blocked by the elastic return force of the drop-off prevention band.
Therefore, when connecting an external connection object to the external connection terminal of the mobile terminal, the cover body and the drop-off prevention band do not get in the way, and in particular, the housing surface on which the opening is formed because the connection object is large. Even if it is completely covered by the connection object, it is not necessary to bend the drop-off prevention band greatly, so that deterioration of the material of the drop-off prevention band is suppressed.

Next, some embodiments for carrying out the present invention will be specifically described with reference to the drawings.
[First Embodiment]

1 to 3 are perspective views showing the appearance of a mobile terminal 1 according to an embodiment to which the connector cover structure of the present invention is applied. FIG. 1 shows the mobile terminal 1 with the cover body 6 closed, 2 shows the portable terminal 1 with the cover body 6 opened, and FIG. 3 shows the portable terminal 1 with the drop-off prevention band 7 and the cover body 6 rotated to a position where the cover body 6 does not get in the way. Show.
FIG. 4 is a perspective view showing a state in which the mobile terminal 1 in the state shown in FIG. 3 is connected to the cradle 100 to be connected.

  The portable terminal 1 of this embodiment is a portable small portable terminal such as a PHS, a cellular phone, a smartphone, and the like, and the casing 2 that forms the exterior of the portable terminal 1 is as shown in FIG. 2 and FIG. An opening 4 is formed corresponding to the position of the USB standard external connection terminal 3 provided with a charging terminal.

  Then, on the one surface 2b of the housing 2, more specifically, on the one surface 2b adjacent to the surface 2a on which the opening 4 is formed, as shown in FIG. An attachment portion 8 for connecting the connector cover 5 to the housing 2 is provided at a location that does not come into contact with the cradle 100 when a certain cradle 100 is connected.

In this embodiment, as shown in FIG. 4, the surface 2 a of the housing 2 in which the opening 4 is formed, that is, the surface 2 a on the side where the external connection terminal 3 is provided is entirely covered by the cradle 100. Therefore, the surface of the housing 2 on which the mounting portion 8 can be disposed has four surfaces 2b (right side surface), 2c (left side surface), 2d (front surface), 2f adjacent to the surface 2a on which the opening 4 is formed. Limited to (back side).
Of these, the surface 2d of the housing 2 is a surface on which the user opens and closes when confirming the built-in display, operating buttons, etc., that is, a surface where the position and orientation with respect to the opening 4 change. It is not suitable as a surface to install.
With respect to the remaining three surfaces 2b, 2c, and 2f of the housing 2, the mounting portion 8 may be allowed to be disposed on the condition that the three surfaces 2b, 2c, and 2f are not in contact with the cradle 100.
More precisely, in the cradle 100 to be connected in this embodiment, as shown in FIG. 4, the opening 4 is formed among the three surfaces 2b, 2c, 2f of the housing 2. Since the portion where the vertical separation distance from the surface 2a is less than H is surrounded by the casing portion of the cradle 100, the mounting portion 8 is actually allowed to be disposed on the surfaces 2b, 2c and 2f. This is a place on any surface and having a vertical separation distance of H or more from the surface 2a on which the opening 4 is formed.

Therefore, in this embodiment, one surface 2b (right side surface) of the housing 2 is selected as a surface on which the mounting portion 8 is disposed, and the surface 2a on the one surface 2b is perpendicular to the surface 2a on which the opening 4 is formed. The attachment portion 8 is provided at a location where the separation distance is equal to or greater than H, that is, a location where the cradle 100 that is a connection target is not in contact with the casing portion of the cradle 100.
The mounting portion 8 can be provided anywhere on the surface 2b where the vertical separation distance from the surface 2a is H or more, but the mounting portion 8 is too far away from the formation surface 2a of the opening 4. If the connector cover 5 is disposed, the entire length of the drop-off prevention band 7 of the connector cover 5 is made redundant and inconvenient to handle, and the material cost required for manufacturing the connector cover 5 is increased, so that the mounting portion 8 is on the surface 2b. Desirably, the vertical separation distance from 2a is slightly larger than H.

  A configuration in which the surface 2a of the housing 2 in which the opening 4 is formed does not come into full contact with the connection object, for example, a small object such as a USB cable connector is exclusively connected. In such a configuration, it is possible to provide the mounting portion 8 on the surface 2a on which the opening 4 is formed and at a location where it does not come into contact with the connector or the like of the USB cable. It is not always essential to provide the attachment portion 8 on a surface other than the surface 2a.

  On the other hand, as shown in FIG. 3, the connector cover 5 is fitted to the opening 4 of the housing 2 and covers the opening 4 so as to be openable and closable. It is comprised by the drop-off prevention belt | band | zone 7 extended toward.

The drop-off prevention band 7 is made of a flexible band-like body such as an elastomer or polypropylene resin, and a fastening part 9 for connecting to a mounting part 8 provided on the one surface 2b of the housing 2 is provided at the tip part 7a. Are integrally formed.
In this embodiment, the cover body 6 and the drop-off prevention band 7 are also completely integrated.
In general, the fitting portion between the cover main body 6 and the opening 4 has a dustproof function and a waterproof function, but the configuration thereof is already known and will not be particularly described.

  An example of the connection structure between the attachment portion 8 and the fastening portion 9 will be described with reference to the cross-sectional view of FIG.

  The mounting portion 8 in this embodiment is a columnar protrusion constituted by a pin planted on the one surface 2b of the housing 2 or a dowel formed integrally on the one surface 2b of the housing 2, and the like. The attachment portion 9 is formed of a hole having a size that allows the attachment portion 8 formed of a columnar protrusion to be fitted in the press-fitted state.

  Although not shown in the drawing, a diameter-enlarged portion for retaining is integrally formed at the distal end of the mounting portion 8 made of a columnar protrusion, and the distal end portion 7a of the drop-off prevention band 7 is temporarily elastically deformed to form a hole. The distal end portion 7a of the drop-off prevention band 7 is attached to the one surface 2b of the housing 2 via the attachment portion 8 by expanding the fastening portion 9 and causing the attachment portion 8 made of a columnar protrusion to enter the attachment portion 9. It is like that.

  Since the tip part 7a of the drop-off prevention band 7 is pivotally supported by the attachment part 8 formed of a columnar protrusion, the drop-off prevention band with the normal line of the one surface 2b of the housing 2 at the position where the attachment part 8 is disposed as the rotation center. 7, that is, the connector cover 5 is allowed to rotate clockwise and counterclockwise about the position of the mounting portion 8 shown in FIG.

  FIG. 5A is a cross-sectional view showing a fitting state of the attachment portion 8 and the fastening portion 9 in a state where the connector cover 5 is rotated to a position where the cover body 6 covers the opening 4, and FIG. 4 is a cross-sectional view showing a fitting state of the attachment portion 8 and the fastening portion 9 in a state where the connector cover 5 is rotated to a position where the connector cover 5 does not interfere with the connection between the housing 2 and the cradle 100. FIG. FIG. 5B shows the posture transition process from the state of FIG. 5A to the state of FIG. 5C or the posture from the state of FIG. 5C to the state of FIG. It is sectional drawing which showed the fitting state of the attaching part 8 and the fastening part 9 in the transfer process.

As shown in FIG. 5 (c), a connector for connecting the housing 2 and the cradle 100 is provided at a contact portion of the fixing portion 9 with the mounting portion 8, that is, an inner peripheral portion of the fixing portion 9 formed of a hole. A convex portion 11b is formed that fits into the concave portion 10b on the outer peripheral surface of the mounting portion 8 in a state in which the connector cover 5 is rotated to a position where the cover 5 does not get in the way, and as shown in FIG. A convex portion 11a is formed to be fitted into the concave portion 10a on the outer peripheral surface of the mounting portion 8 in a state where the connector cover 5 is rotated to a position where the cover body 6 covers the opening portion 4. In each posture shown in FIG. 5C and FIG. 5A, a click stop is applied to the rotation of the drop-off prevention band 7.
Further, in the transition process of the posture of the drop-off prevention band 7 as shown in FIG. 5B, at least one of the convex portions 11a and 11b provided on the inner peripheral portion of the fastening portion 9 is Since it is pressed by the outer peripheral surface of the mounting portion 8 and is compressed and deformed within the elastic limit, the reaction force acts as a frictional resistance, and an appropriate resistance is given to the rotation operation of the drop-off prevention band 7.

  Of course, the same operation and effect can be obtained by providing a convex portion instead of the concave portions 10a and 10b and providing a concave portion instead of the convex portions 11a and 11b.

  As shown in FIG. 1, when connecting the mobile terminal 1 in which the opening 4 of the housing 2 is covered with the cover body 6 of the connector cover 5 to the cradle 100, first, the cover body 6 has a nail. The cover body 6 and the opening 4 are released from each other by pulling and pulling forward, and the cover body 6 is opened as shown in FIG.

In the state where the cover body 6 is opened, that is, in the state where no restraining force is applied to the drop-off prevention band 7, the posture of the cover body 6 is as shown in FIG. Since the halfway state is maintained, there is an inconvenience that the cover body 6 becomes an obstacle when the external connection terminal 3 of the mobile terminal 1 and the connection terminal 101 of the cradle 100 are connected.
This problem is a problem common to conventional portable terminals in which a band body made of an elastomer or the like is used as a drop-off prevention band or a simple hinge to open and close the cover body.
In the conventional portable terminal, the USB cable connector and the like were connected with the cover body pressed against the elastic body against the elastic restoring force of the band and opened, but the work was troublesome, When connecting to a large connection object such as a cradle that covers the entire surface of the housing provided with openings for the external connection terminals, the cover body is inverted 180 °. Since it is necessary to open, in addition to the troublesome operation, there is also the inconvenience that the belt-like body functioning as a hinge or the like is likely to be deteriorated by bending.

  Therefore, in this embodiment, an unreasonable operation that largely bends the drop-off prevention band 7 is not performed, and the connector cover 5 is centered on the attachment portion 8 from the state of FIG. The cover body 6 is retracted from the front of the opening 4 by rotating it counterclockwise and moving the cover body 6 to the back surface 2 f side of the housing 2.

  When the drop-off prevention band 7 rotates to a position where the connector cover 5 does not get in the way of connection between the housing 2 and the cradle 100, that is, a position as shown in FIGS. 3 and 4, it is formed on the outer peripheral surface of the mounting portion 8. The convex portion 11b of the fastening portion 9 is fitted to the concave portion 10b as shown in FIG. 5C, and a click stop is applied to the posture change of the drop-off prevention band 7.

  As shown in FIG. 6, the cradle 100 according to this embodiment is configured so that the portable terminal 1 stands upright with the surface 2 a on which the opening 4 for the external connection terminal 3 is formed facing downward. Although the external connection terminal 3 and the connection terminal 101 of the cradle 100 are connected, as described above, the position of the drop-off prevention band 7 under the condition that the cover body 6 is moved to the back surface 2f side of the housing 2. Since the click stop is automatically applied to the change, there is no possibility that the connector cover 5 moves downward, that is, toward the opening 4 due to inadvertent rotation of the drop-off prevention band 7 due to the weight of the connector cover 5. Therefore, the external connection terminal 3 on the housing 2 side can be reliably connected to the connection terminal 101 of the cradle 100 without holding the connector cover 5 with a finger.

  In addition, there is no need to strongly bend the drop-off prevention band 7 in order to retract the cover body 6 from the opening 4 of the housing 2, so that the material of the drop-off prevention band 7 deteriorates due to repeated bending operations. It does not occur at all.

  Further, since the connection work is facilitated and troublesome, the other terminals other than the external connection terminals 3, for example, terminals that are used frequently for charging, are arranged so as to be exposed to the outside of the housing 2. The necessity of facilitating the charging operation is eliminated, and the manufacturing cost of the portable terminal 1 can be reduced.

  On the other hand, when the opening 4 of the housing 2 is covered with the cover body 6 on the contrary, the connector cover 5 in the state shown in FIG. 3 is rotated clockwise in FIG. The cover body 6 is moved to the front side of the opening 4 of the housing 2. In this case, the cover body 6 is moved to the outer peripheral surface of the mounting portion 8 when the drop-off prevention band 7 is rotated to the position as shown in FIG. By fitting the convex portion 11a of the fastening portion 9 into the formed concave portion 10a as shown in FIG. 5A, the cover main body 6 is accurately positioned in front of the opening portion 4. .

  Therefore, in the state shown in FIG. 2, the cover body 6 is appropriately fitted to the opening 4 by a simple operation of pressing the cover body 6 toward the opening 4, and the opening is made as shown in FIG. 4 can be closed properly.

[Modification of First Embodiment]

As described above, the connector cover structure has been described in which the mounting portion 8 on the housing 2 side is configured with a columnar protrusion and the fastening portion 9 on the connector cover 5 side is configured with a hole. The attachment part 8 on the body 2 side may be configured by a hole, the fastening part 9 on the connector cover 5 side may be constituted by a columnar protrusion, and the fastening part 9 may be fitted inside the attachment part 8.
[Second Embodiment]

  Next, the configuration of the mobile terminal 12 of another embodiment to which the connector cover structure of the present invention is applied will be briefly described.

7 to 9 are perspective views showing the appearance of the mobile terminal 12 of the present embodiment. FIG. 7 shows the mobile terminal 12 with the cover main body 13 closed, and FIG. 8 shows the cover main body 13 opened. Further, FIG. 9 shows the portable terminal 12 in a state where the drop-off prevention bands 14 and 14 and the cover main body 13 are rotated to a position where the cover main body 13 does not get in the way.
10A is a plan view showing the mobile terminal 12 of the embodiment, FIG. 10B is a left side view showing the mobile terminal 12, and FIG. 10C is a right side showing the mobile terminal 12. FIG. 10D is a bottom view showing the mobile terminal 12.
The cradle to be connected is the same as the cradle 100 of the first embodiment described with reference to FIG. 4 and FIG.

  As shown in FIGS. 8 and 9, the housing 15 that forms the exterior of the portable terminal 12 has an opening 4 corresponding to the location of the USB standard external connection terminal 3 having a charging terminal. It is installed.

The housing 4 is adjacent to the surface 15a of the housing 15 in which the opening 4 is formed and is parallel to each other on each of the two surfaces 15b (right side) and 15c (left side). Mounting portions 16 and 16 made of columnar protrusions are symmetrically arranged at locations where the cradle 100 does not contact the cradle 100 when the cradle 100 is connected to the 15 external connection terminals 3.
The structure of the attachment parts 16 and 16 is the same as that of the attachment part 8 in the first embodiment described above, but is different from the first embodiment in that it is provided symmetrically on both the left and right sides of the housing 15. Different.

  On the other hand, the cover main body 13 of the connector cover 17 has two drop-off prevention bands 14 and 14 made of a flexible belt-like body such as elastomer or polypropylene resin, as shown in 10 (d), for example. 13 are provided symmetrically so as to extend outward from both sides of the outer peripheral portion.

  Further, fastening portions 18 and 18 for connecting to mounting portions 16 and 16 provided on the two surfaces 15b and 15c of the casing 15 are integrally formed at the respective distal end portions 14a and 14a of the drop-off prevention bands 14 and 14. Is formed.

  As shown in FIGS. 10 (b) and 10 (c), the fastening portions 18 and 18 of this embodiment are configured by holes, and the configuration thereof is the same as that of the fastening portion 9 in the first embodiment described above. Similarly, in this embodiment, each of the fall-off prevention bands 14, 14 is further provided with an auxiliary fastening comprising a slit 19 extending from the fastening portion 18 toward the cover body 13 and a hole communicating with the slit 19. It differs from the first embodiment described above in that the portion 20 is formed.

  More specifically, as shown in FIGS. 10 (b) and 10 (c), the auxiliary fastening portion 20 is fitted with the attachment portion 16 formed of a columnar protrusion in a state where the cover body 13 is fitted into the opening 4. As shown in FIGS. 7 and 8, the fastening portion 18 provided at the mating position is a mounting portion made of a columnar protrusion in a state where the cover main body 13 is separated from the front side of the opening 4. 16 is provided at a position where it can be fitted.

  As shown in FIG. 7, when connecting the mobile terminal 12 with the cover body 13 of the connector cover 17 covered with the opening 4 of the housing 15 to the cradle 100, first, the cover body 13 is attached to the nail. The cover body 13 and the opening 4 are released from each other by pulling and pulling forward, and the cover body 13 is opened as shown in FIG.

  As the cover body 13 is pulled forward in this way, the auxiliary fastening portions 20 and 20 of the drop-off prevention bands 14 and 14 fitted to the mounting portions 16 and 16 on the housing 15 side made of columnar protrusions are formed. The slits 19 and 19 are expanded by the elastic deformation of the front end portions 14a and 14a of the drop-off prevention bands 14 and 14 and the mounting portions 16 and 16 are relatively moved along the slits 19 and 19 while being pulled out from the mounting portions 16 and 16 toward the front side. In the end, the fastening portions 18 and 18 of the drop-off prevention bands 14 and 14 are fitted into the mounting portions 16 and 16 on the housing 15 side.

  In this embodiment, since the two drop-off prevention bands 14 are provided so as to extend outward from the outer peripheral portions of the left and right ends of the cover main body 13, the cover main body 13 is in the state where the cover main body 13 is pulled out. As shown in FIG. 8, the main body 13 is placed at a certain distance in front of the opening 4 of the housing 15, more specifically, an interval corresponding to the separation distance between the fastening part 18 and the auxiliary fastening part 20. Will be located.

  Therefore, in the present embodiment, the connector cover 17 including the drop-off prevention bands 14 and 14 and the cover main body 13 is shown in FIG. 8 from the state shown in FIG. The cover main body 13 is moved from the front of the opening 4 as shown in FIG. 9 by rotating the cover counterclockwise to move the cover main body 13 to the back surface 15f side of the housing 15.

  Then, when the drop-off prevention bands 14 and 14 are rotated to a position where the connector cover 17 does not interfere with the connection between the casing 15 and the cradle 100, that is, the position shown in FIG. 9, the same as in the first embodiment described above, The convex portions of the fastening portions 18, 18 are fitted into the concave portions formed on the outer peripheral surfaces of the attachment portions 16, 16, and a click stop is applied to the posture change of the drop-off prevention bands 14, 14.

  Therefore, as in the first embodiment described above, there is no possibility that the connector cover 17 will move downward, that is, toward the opening 4 side due to inadvertent rotation of the drop-off prevention bands 14 and 14 due to the weight of the connector cover 17, and with a finger. Even without holding the connector cover 17, the external connection terminal 3 on the housing 15 side can be reliably connected to the connection terminal 101 of the cradle 100.

  In addition, since it is not necessary to bend the fall-off prevention bands 14 and 14 in order to retract the cover body 13 from the opening 4 of the housing 15, the material of the fall-off prevention bands 14 and 14 is deteriorated due to repeated bending operations. There is no inconvenience.
