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

  2 to 5 show a slide type mobile phone 1 according to an embodiment of the present invention. The slide type mobile phone 1 has a first housing 3 having a display unit 2 on the front side and an operation unit on the lower side. Closed state (shown in FIGS. 1, 2, 4, and 7) that overlaps the second housing 5 having 4, and the first housing 3 slides on the second housing 5 to make the second It is configured to be switchable between an open state (shown in FIGS. 3, 5, and 8) in which the operation unit 4 of the housing 5 is exposed. The first substrate 6 in the first housing 3 and the second substrate 7 in the second housing 5 are electrically connected by a signal line 30 (see FIGS. 6 and 9). Although not shown in detail, the signal line 30 includes, for example, two bundles 30a in which 20 shielded thin wires are bundled and covered with a braid. For convenience of explanation, the longitudinal direction (sliding direction) of the first housing 3 is the vertical direction, and the width direction is the horizontal direction.

  The first housing 3 is slidably connected to the second housing 5 via a slide mechanism 10. As shown in FIGS. 1, 6, 7, and 8, the slide mechanism 10 includes a slider 11 that is attached to the front side of the second housing 5 and is made of a press-formed product of, for example, a stainless steel plate. Yes. The slider 11 has a rectangular thin plate shape, and as shown in FIG. 6, the slider 11 includes an engagement portion 12 whose left and right end portions are bent to the front side to have an L-shaped cross section. For example, four fastening holes 13 (see FIG. 7) for fastening to the second housing 5 are formed in the slider 11. The slider 11 is fastened to the upper side of the second casing 5 in the closed state shown in FIG. When the slider 11 is viewed from the back, a signal line through hole 14 through which the signal line 30 passes is cut out at the lower left end.

  On the other hand, as shown in an exploded view in FIG. 9, the first housing 3 has a first cabinet 3a made of a metal insert molded product, and the first cabinet 3a has a stainless steel sheet 3b inserted in the center portion. ing. An LCD panel 2a, an LCD cushion 2b, and an LCD unit 2c constituting the display unit 2 are attached to the first cabinet 3a. The first substrate 6 is connected to the back surface of the LCD unit 2c. A rectangular thin plate-like back plate 20 made of a magnesium alloy molded product or the like is fastened to the back surface of the first cabinet 3a by screws 20a. As shown in FIG. 5, the back plate 20 is exposed in the open state, and thus a paint that matches the color of the first cabinet 3 a or the like is applied. Resin covers 20b and 20c for hiding the first substrate 6 and the like are attached to the upper and lower sides of the back plate 20, respectively. As shown in FIG. 6, the left and right end portions of the back plate 20 are bent outward in a L-shaped cross section to form rail portions 21. For example, the rail portion 21 is fitted with a sliding contact member 21a made of, for example, resin for improving sliding. The rail portion 21 constitutes a part of the slide mechanism 10, the engaging portion 12 of the slider 11 is engaged with the rail portion 21, and the slider 11 can slide up and down along the rail portion 21.

  A gap 22 through which the signal line 30 can move is formed between a portion surrounded by the left and right rail portions 21 on the back surface of the first housing 3 and the surface of the slider 11. The height H of the gap 22 in the thickness direction of the first housing 3 is, for example, about 2 mm. As shown in FIG. 1, a bulging portion 23 is formed in the gap 22 on the lower right side when viewed from the back. The bulging portion 23 has a groove portion 24 extending in the vertical direction, and the groove portion 24 is inclined to the left side when viewed from the back before the linear portion 24a extending vertically below and the upper end in the sliding direction (fully opened position). And an inclined portion 24b. A cutout 24c is formed at the lower end of the straight line portion 24a, and the first substrate 6 side of the signal line 30 accommodated in the groove portion 24 extends from the cutout 24c (see FIG. 9). A long and thin connection terminal 30b for connection is connected. The width of the straight portion 24a is equal to or slightly larger than the width when the two bundles 30a are arranged, the upper end of the inclined portion 24b is gradually widened, and the corner of the wall surface is rounded. With such a configuration, the signal line 30 of the portion accommodated in the straight portion 24a hardly moves, but the inclined portion 24b can move slightly in the inclined portion 24b in accordance with the slide operation. It has become. This prevents the signal line 30 from being repeatedly loaded and damaged at the upper end portion of the inclined portion 24b.

  Further, as shown in FIG. 8, an intrusion prevention portion 26 extending perpendicularly to the slide direction (in the left-right direction) is formed on the lower end side of the bulging portion 23 so as to extend along the lower end portion of the slider 11 in the opened state. ing.

  The signal line 30 extending from the upper end of the inclined portion 24b is bent so as to move while maintaining a substantially U shape in front view in the gap 22, and the tip on the second substrate 7 side is the signal line through hole 14 of the slider 11. It extends to the second housing 5 side through and is finally connected to the second substrate 7. As shown in FIG. 7, the signal line through hole 14 and the bulging portion 23 are arranged so as to be farthest apart in the closed state in which the first casing 3 and the second casing 5 overlap.

  The signal line through hole 14 is provided with a locus adjusting member 35 that adjusts the locus of the signal line 30 by inclining the signal line 30 extending into the gap 22 with respect to the sliding direction. As shown in FIGS. 10 and 11, the trajectory adjusting member 35 is made of a resin molded product that can be attached to and detached from the signal line through hole 14, so that the signal line 30 can be sandwiched therebetween, A fitting cover 37 that covers the restricting member main body 36 is provided. The fitting cover 37 is provided with a pair of engaging claws 37a, and the regulating member main body 36 is sandwiched between the pair of engaging claws 37a. In a state where the fitting cover 37 is fitted to the regulating member main body 37, the rectangular inner opening 38 into which the signal line 30 in the gap 22 is inserted and the signal line 30 are bent vertically so that the second housing 5 is inserted. A circular outer opening 39 connected to the side is formed. As shown in FIGS. 1 and 7, the signal line through hole 14 has a rectangular shape on the gap 22 side (right side when viewed from the back) according to the shape of the trajectory adjusting member 35, and the second substrate 7 side (same left side). ) Is circular. On the gap 22 side of the signal line through hole 14, an extended portion 14 a is formed in a portion through which the signal line 30 passes. A pair of inner locking portions 36a is formed in the restricting member main body 36 so as to surround the expanded portion 14a. Similarly, an outer locking portion 36b is formed on the second substrate 7 side facing the inner locking portion 36a.

  For example, as shown in FIG. 11, the two bundles 30 a of the signal lines 30 sandwiched by the trajectory adjusting member 35 are covered with a mark tape 31 and used as marks. This portion of the mark tape 31 is placed on the regulating member main body 36, covered with the fitting cover 37, and the signal line 30 is held. In this state, the U-shaped portion of the signal line 30 is inserted into the gap 22, The wire through hole 14 is passed through the signal line 30 through the extended portion 14a, the inner locking portions 36a are arranged on both sides of the extended portion 14a, and the outer locking portions 36b are brought into contact with the peripheral edge of the signal line through hole 14. It has become. By doing so, the length of the portion inserted into the gap 22 of the signal line 30 is maintained in an optimal state, and the signal line 30 is fixed to the slider 11.

  Then, most of the slider 11 is formed of a sheet metal press-molded product that can be easily processed into a thin plate, and the locus adjusting member 35 of the portion where the signal line 30 is bent vertically to the second housing 5 side is also formed in a complicated shape. Since it is made of a resin molded product that can be easily processed, a lightweight and highly rigid slider 11 can be obtained, and a shape capable of tilting the tilt direction of the signal line 30 can be easily formed. Further, since the locus adjusting member 35 is made of resin, the signal line 30 is less likely to be scratched than when it is brought into direct contact with the slider 11.

  In the open state shown in FIG. 8, the signal line 30 has the smallest inner minimum bending radius R, but the inner minimum bending radius R is kept at 4 mm or more.

  The gap 22 has one end 40a rotatably connected to the first housing 3 (back plate 20) and the other end 40b rotatably connected to the second housing 5 (slider 11). An L-shaped leaf spring 40 is provided. The end portions 40a and 40b of the leaf spring 40 are each provided with an annular portion 40c, and each annular portion 40c is fixed (formed) on the surface side where the end portions 40a and 40b approach each other. The signal line 30 is configured to move in the gap 22 surrounded by the leaf spring 40 and the bulging portion 23.

  The bulging portion 23 extends to the vicinity of the one end 40 a side of the leaf spring 40, and the signal line 30 slides near the end (upper end) in the sliding direction of the groove 24 in the bulging portion 23 at the closed position of the first housing 3. A direction restricting portion 25 that restricts the direction so as to be parallel to the direction is formed extending in the vertical direction.

  The signal line 30 and the leaf spring 40 are configured to move, for example, in a region surrounded by the four fastening holes 13 in the gap 22.

  And as shown in FIG.1 and FIG.12, the part in which the groove part 24 is formed in the bulging part 23 is covered with resin sheets 50, such as PET and an acrylic resin, from the back side. The resin sheet 50 is colorless and transparent, and has a shape that covers the entire surface of the bulging portion 23 and a part of the resin cover 20c. A pair of positioning recesses 27 are formed on the periphery of the groove 24 so as to sandwich the groove 24. The double-sided tape 51 has the same color as the back plate 20 such as black, and the outer shape is almost the same as that of the resin sheet 50, but the portion facing the groove 24 is cut out. A positioning notch 52 is formed by cutting the position of the positioning recess 27 continuously from this portion. An L-shaped protrusion 28 is formed at the upper end of the bulging portion 23 so as to match the corners of the resin sheet 50 and the double-sided tape 51.

  With this configuration, when one surface of the double-sided tape 51 is affixed to the resin sheet 50, portions corresponding to the groove 24 and the positioning recess 27 can be seen. In this state, the other surface of the double-sided tape 51 is placed on the bulging portion 23 and the resin so that the positioning notches 52 are aligned with the positioning recesses 27 while the corners of the resin sheet 50 and the double-sided tape 51 are applied to the protrusions 28. The tape is attached to the recessed portion 20d for tape of the recessed cover 20c. At this time, since the resin sheet 50 is colorless and transparent, and the double-sided tape 51 is colored, it can be confirmed that the signal line 30 is accommodated in the groove portion 24 from a portion where the double-sided tape 51 is not present. Positioning is easy when affixed to the bulging part 23. A resin cover 20c that covers the connection terminal 30b with the double-sided tape 51 at the time of assembly is also attached at the same time, so that it is temporarily fixed and easy to handle. And since the signal line 30 accommodated in the groove part 24 is not adhere | attached on the double-sided tape 51, it is not completely fixed in the groove part 24, but the signal line 30 can move suitably in the groove part 24 with a slide operation. It is like that. Further, by covering the signal line 30 accommodated in the groove portion 24 with the resin sheet 50, the signal line 30 is reliably prevented from protruding from the groove portion 24 and being sandwiched between the periphery of the groove portion 24 and the slider 11 and being damaged. ing.

  The signal line 30 is covered with a mark tape 31 at a position corresponding to the positioning recess 27. For this reason, the length of the signal line 30 in the gap is maintained at a predetermined length by aligning the positioning concave portion 27 and the mark tape 31 and accommodating the signal line 30 in the groove portion 24. Too much contact with other parts and damage, or too short to cut.

-Signal line movement with slide operation-
Next, the movement of the signal line 30 accompanying the sliding operation of the sliding mobile phone 1 according to the present embodiment will be described.

  First, in the closed state shown in FIGS. 1, 2, 4, and 7, the trajectory adjusting member 35 is at a position farthest from the bulging portion 23 in the vertical direction. The first substrate 6 side of the signal line 30 is regulated in the vertical direction by the linear portion 24a of the groove portion 24, and the portion protruding from the inclined portion 24b rises up and down after being brought inward in the left and right directions. However, the signal line 30 is not bent further to the right side when viewed from the back by the direction restricting portion 25 at the upper end of the bulging portion 23.

  On the second substrate 7 side, the locus of the signal line 30 is adjusted by greatly tilting the second housing 5 side to the right when viewed from the back with respect to the vertical direction by the locus adjustment member 35, so that the signal line 30 does not contact the inner surface of the leaf spring 40. In addition, since the leaf spring 40 is L-shaped when viewed from the front, the leaf spring 40 does not have a coil portion, can easily avoid contact with the signal line 30, and the movable area of the signal line 30 is widened. In addition, since the annular portion 40c of the leaf spring 40 is fixed to the left and right surfaces close to each other (the left and right inner sides), it is farther from the signal line 30 than the case where the annular portion 40c is provided on the opposite side of the surfaces close to each other. Therefore, it is easier to avoid contact with the signal line 30. Thus, when the signal line through hole 14 is farthest from the bulging portion 23 in the closed position, it is effectively prevented that the U-shaped open portion opens too much and contacts the leaf spring 40.

  As shown in FIG. 7, even if a thin foreign object 101 such as a ticket enters the gap 22 in which the signal line 30 moves, the thin foreign object 101 is formed by the intrusion prevention unit 26 formed by extending the bulging part 23. Is prevented from penetrating deeper, so that the thin foreign matter 101 can be easily taken out.

  Next, when the first housing 3 is opened and the operation unit 4 of the second housing 5 is used, the lower end portion of the first housing 3 is pushed up with a finger against the urging force of the leaf spring 40. .

  Then, when the sliding amount is about half, the torsion angle of the leaf spring 40 becomes maximum, and then the first housing 3 opens with the urging force of the leaf spring 40 even if the hand is released, and FIG. 5 and FIG. 8 are in the open state (fully open position). Even in the opened state, as shown by a two-dot chain line in FIG. 8, the leaf spring 40 and the signal line 30 are not visible from the upper side of the second housing 5. When the first housing 3 is in the fully open position, the entire region of the groove 24 is covered by the slider 11. For this reason, even if a force is applied to open the first housing 3 with respect to the second housing 5 and the gap 22 is slightly widened, the signal line 30 is between the slider 11 and the groove 24. Since it is pinched, it is stable and the signal line 30 is prevented from being bitten. Further, since the trajectory of the signal line 30 can be appropriately regulated, the coupling area of the slider 11 can be made as wide as possible, and the rigidity when the first housing 3 is opened most is high.

  Even when such a sliding operation is repeated, the inner minimum bending radius R of the signal line 30 can be maintained at 4 mm or more by the trajectory adjusting member 35, so that the signal line 30 is less likely to be damaged (the following durability test). reference). In addition, since the upper end of the inclined portion 24b is gradually widened, the signal line 30 coming out of the inclined portion 24b is not suddenly bent near the upper end, so that the durability of the signal line 30 is improved. Further, since the signal line 30 is accommodated in the inclined part 24b, the signal line 30 can be easily held within the inclined part 24b in a direction approaching the trajectory adjusting member 35, and the signal line 30 bent into a U shape by being inclined in this direction. It is regulated so that the open side is not too wide. As described above, the trajectory adjusting member 35 and the groove portion 24 are configured so that the trajectory of the signal line 30 accompanying the slide operation is limited to a narrow range, so that the signal line 30 does not come into contact with other parts and is not damaged.

-Signal line durability test-
As shown in FIG. 13, the gap 122 was formed in the polycarbonate pseudo casing 100 of the slide tester, and the endurance test of the signal line 30 was performed by changing the groove width W and height H of the gap 122. One end of the signal line 30 was connected to the upper side of the pseudo casing 100, and the other end was connected to the lower side. The signal line 30 is a set of two bundles 30a having a diameter of 1.5 mm in an unloaded state. Each N number was 3.

  As shown in FIG. 13, the signal line 30 was disconnected at any height H when the groove width W = 12 mm. At the groove width W = 14 mm, the wire was disconnected at the height H = 1.2 mm, but there was no wire breakage at the height H = 1.4 mm or more. Assuming the groove width W = 16 mm, there was no disconnection at any height H. From this result, it was found that if the height H was 1.4 mm or more, no disconnection occurred even with the groove width W = 14 mm. The groove width W = 14 mm corresponds to the case where the inner minimum bending radius R of the signal line 30 is approximately 4 mm. Therefore, it was found that the inner minimum bending radius R at the gap 22 immediately after exiting the trajectory adjusting member 35 in the open state of FIG. 8 may be set to be 4 mm or more.

  Therefore, according to the slide type mobile phone 1 according to the present embodiment, one end side of the signal line 30 is arranged along the sliding direction by the groove portion 24 of the bulging portion 23, and the other end side is slid by the locus adjusting member 35. By tilting in the direction of tilting, the movement of the signal line 30 associated with the slide operation is restricted, and damage to the signal line 30 can be prevented and component placement can be facilitated.
