Description

  The present invention relates to a flexible cable, and more particularly to a flexible cable that is folded when being carried and is applied to a foldable mobile phone having a structure that is automatically opened by performing a button operation when making a call.

  Structurally, mobile phones are classified into a foldable mobile phone having a foldable structure and a so-called stick-type mobile phone having no foldable structure. Folding type mobile phones are classified into a structure that is manually opened and a structure that is automatically opened by operating a button.

  Since the foldable mobile phone is considerably smaller in the folded state than the rod-type mobile phone, it is convenient to carry. Also, the mobile phone is often used when the user is doing some other work, and one hand is often blocked during this work. A cellular phone having a structure that is automatically opened by performing a button operation can be opened by one-hand operation, and is easy to use. Therefore, it is desirable that the folding mobile phone has a structure that can be operated only with the remaining one hand, that is, a structure that is automatically opened by performing a button operation.

  1A and 1B show a cellular phone 10 having a structure that is automatically opened as an example of the prior art. The cellular phone 10 includes an operation key side casing 11, a display unit side casing 12, and a hinge 13 that couples both. The operation key side housing 11 includes an operation key 14 and a microphone 15. The display unit side body 12 includes a liquid crystal panel 16 serving as a display unit, an antenna 17, a speaker 18, and the like. A hinge module 19 is incorporated in the hinge 13. By the hinge module 19, the display unit side body 12 is spring-biased in the opening direction with respect to the operation key side body 11. A button 20 is provided near the hinge 13 on one side surface 11 a of the operation key side housing 11.

  Normally, as shown in FIG. 1A, the mobile phone 10 is in a closed state in which the display unit side body 12 is closed and coupled to the operation key side body 11 by the lock claw 21.

  When making a call, the user holds the foldable mobile phone 10 in a closed state with the operation key side housing 11 placed on the palm of the left hand 30 and grips it with the left hand 30, and presses the button with the thumb 31 of the gripped left hand 30. Press 20. When this operation is performed, the lock claw 21 is moved and retracted via the rotation lever 22, the lock on the display unit side body 12 is released, and the display unit side body 12 is operated by the spring in the hinge module 19. It is rotated with respect to the side housing 11 and opened as shown in FIG. As a result, the user can make a call by placing the mobile phone 10 on the ear.

  Since the cellular phone 10 is small in size, when the folded folding cellular phone 10 is grasped with the left hand 30 and the button 20 is pushed with the thumb 31, a part of the thumb 31 is displayed on the display unit side housing. It tends to come into contact with one side surface 12 a of the body 12, or the other finger 32 is in contact with the side surface 12 b on the opposite side of the display unit side body 12.

  In this state, the finger of the left hand 30 that is in contact with the side surfaces 12a and 12b of the display unit side body 12 becomes a resistance, and the display unit side body 12 cannot be smoothly opened.

  Then, an object of this invention is to provide the flexible cable which solved the said subject.

  The invention of claim 1 has a conductor pattern constituting an internal conductor and a conductor pattern constituting an external conductor in addition to a signal transmission pattern on a flexible base, and the base constitutes the internal conductor. An internal insulator is formed between the conductor pattern and the conductor pattern constituting the outer conductor.

  According to the first aspect of the present invention, a flexible cable having a normal signal transmission pattern and a coaxial cable structure can be realized.

  The best mode for carrying out the invention will be described below.

[First embodiment]
2 (A), 2 (B) and 3 (A), 3 (B), 3 (C) show a foldable mobile phone having a structure that is automatically opened when the lock release button according to the first embodiment of the present invention is pressed. A telephone 50 is shown. FIGS. 2A and 3 show the folded state when carried. A left hand 30 indicated by a two-dot chain line indicates a state in which the cellular phone 50 that is folded is held and unlocked and opened. FIG. 2B shows a state during an open call. A left hand 30 indicated by a two-dot chain line indicates a state of holding the opened mobile phone 50. X1 and X2 are axial directions of the hinge 53, Y1 and Y2 are longitudinal directions of the mobile phone 50, and Z1 and Z2 are thickness directions of the mobile phone 50.

  As shown in FIGS. 2 and 3, the mobile phone 50 includes an operation key side casing 51 that is a fixed casing, a display section casing 52 that is a movable casing, and a hinge 53 that connects the two. Have

  The display unit side body 52 is locked and closed as described later, and is spring-biased in the opening direction with respect to the operation key side body 51 as described later.

  Normally, as shown in FIG. 2A, the cellular phone 50 is in a folded state with the display unit side body 52 closed and locked. When making a call, the user places the operation key side casing 51 on the palm of the left hand 30 and grips it with the left hand 30 and locks it with the thumb 31 of the gripped left hand 30. Press the release button 56. When this operation is performed, the lock on the display unit side body 52 is released, and the display unit side body 52 is rotated in the A1 direction with respect to the operation key side body 51 by the spring in the hinge 53. It is opened as shown in (B). As a result, the user can make a call by placing the mobile phone 50 on the ear.

  4 and 5 are cross-sectional views of the cellular phone 50 in a folded state, taken along the XZ plane indicated by reference numerals IV and V, respectively. FIG. 6 is an exploded view of the hinge 53 portion and the lock mechanism portion of the cellular phone 50 in the opened state. 7A, 7B, and 7C are views showing the hinge 53 portion and the lock mechanism portion of the cellular phone 50 in the opened state. 8A, 8B, and 8C are diagrams showing the lock release button member. 9 (A), (B), (C), FIGS. 10 (A) to (D), and FIGS. 11 (A) to (D) are cross-sectional views taken along different positions in FIG. 7 (B). is there.

  The operation key side casing 51 is generally configured such that a printed circuit board 64 on which electronic components are mounted is housed in a box made up of a box-shaped housing body 62 and a cover 63. Similarly, the display unit side body 52 has a configuration in which a printed circuit board 67 on which electronic components are mounted is housed in a box made up of a box-shaped housing body 65 and a cover 66.

  Next, the cover parts 54 and 55 will be described.

  As shown in FIGS. 1 to 7, the cover portion 54 projects in the Z1 direction from the portion near the hinge 53 on the side surface 51a on the X2 direction side of the operation key side housing 51 (housing main body 62) and extends in the Y1 direction. It has an overhang and is formed to bulge in the X2 direction, and has a Z1 direction overhang 54z1 overhanging in the Z1 direction and a Y1 overhang 54y1 overhang in the Y1 direction. The overhanging portion 54z1 covers the side surface 52a on the X2 direction side of the display unit side body 52 of the cellular phone 50 in a folded state. A surface 74a of a cover member 74, which will be described later, which is an inner surface of the overhanging portion 54z1, and a side surface 52a of the display unit side body 52 are not in contact with each other, as shown in FIGS. A gap 68 exists.

  The cover portion 55 extends in the Z1 direction and extends in the Y1 direction from the portion near the hinge 53 on the side surface 51b on the X1 direction side of the operation key side housing 51 (housing main body 62), similarly to the cover portion 54 described above. And has a Z1 direction projecting portion 55z1 projecting in the Z1 direction and a Y1 direction projecting portion 55y1 projecting in the Y1 direction. The overhang portion 55z1 covers the side surface 52b on the X2 direction side of the display unit side body 52 of the cellular phone 50 in a folded state. The inner wall 55a of the overhanging portion 54z1 and the side surface 52b of the display unit side body 52 are not in contact with each other, and as shown in FIGS. 4 and 5, a slight gap 69 exists between them.

  Therefore, when making a call, the user holds the operation key side casing 51 on the palm of the left hand 30 and grips it with the left hand 30, and the lock release button 56 with the thumb 31 of the left hand 30. When the button is pressed, the portion of the thumb 31 that protrudes from the lock release button 56 contacts the cover 54, and does not contact the side surface 52 a of the display unit side body 52. Further, the other fingers 32 are exclusively in contact with the cover portion 55 on the opposite side, and do not contact the side surface 52b of the display unit side body 52. For this reason, the side surfaces 52 a and 52 b on both sides of the display unit side body 52 are free with respect to the left hand 30, and the display unit side body 52 is restricted from rotating in the opening direction by a part of the left hand 30. The display unit side body 52 starts to rotate smoothly, and the display unit side body 52 opens smoothly.

  Next, the lock mechanism 70 and the unlock operation mechanism 77 will be described.

  Here, the lock mechanism 70 and the lock release operation mechanism 77 are closely related and will be described together without being described separately.

  As shown in FIGS. 6 and 7, the cover portion 54 of the side surface 51a on the X2 direction side of the operation key side casing 51 has a space portion 54a inside, and the lock mechanism 70 and the lock release operation mechanism 77 It is incorporated using the space 54a.

  A lock member 71, a shaft member 72, a compression coil spring 73, and a cover member 74 shown in FIG. 8 are incorporated in the space portion 54 a inside the cover portion 54.

  The cover member 74 has the Y1 direction end 74c locked between the end of the operation key side casing 51 and the cover 54, and the Y2 direction end is fixed by a screw 75. The opening on the X1 direction side of 54a is covered.

  The lock member 71 includes a bearing portion 71a, arm portions 71b and 71c extending to both sides from the bearing portion 71a, a hook portion 71d at the tip of the arm portion 71b, and a lock release button 56 at the tip of the arm portion 71c. The lock release button 56 is a part of the lock member 71.

  The lock member 71 is provided so that the bearing portion 71a is supported by a shaft member 72 penetrating the cover portion 54 in the Z1-Z2 direction and extends in Y1-Y2, and the lock release button 56 is provided on the cover portion 54. The hook portion 71d protrudes in the X1 direction from the cutout portion 74b of the cover member 74, and is fitted to the side opening 54b and exposed to the outside. The lock member 71 is urged in the B1 direction by a compression coil spring 73 between the lock release button 56 and the cover member 74.

  The lock release button 56 is arranged at a position shifted by dimension a in the Y2 direction from the axis CL53 of the hinge 53, that is, at a position near the hinge 53, not at the position of the hinge 53.

  The hook portion 71d protrudes in the X1 direction at a position slightly above the upper surface of the operation key side casing 51 in the Z1-Z2 direction. A concave portion 52a1 is formed on the side surface 52a of the display unit side body 52 at a position where the hook portion 71d faces in the closed state. When the hook portion 70d is fitted in the recess 52a1, the display unit side body 52 is locked in the closed state shown in FIG.

  When the lock release button 56 is pressed, the lock member 71 is rotated in the B2 direction, the hook portion 71d is retracted into the space portion 54a, is detached from the recess 52a1, and the lock is released.

  Here, the bearing portion 71a is a fulcrum, the lock release button 56 is a force point, and the hook portion 71d is an action point. When the length of the arm portion 71b is L1 and the length of the arm portion 71c is L2, L1 <L2. Therefore, by the lever principle, the force for pressing the unlock button 56 is reduced, and the unlocking operation is a lighter force than before, and preferably a force of about 300 gr.

  The lock mechanism 70 has an arm-shaped lock member 71 and has a relatively bulky structure. However, the lock mechanism 70 is housed in the space 54 a inside the cover 54, and the size of the mobile phone 50 is small. ing.

  The hook portion 70 d of the lock member 71, the recess 52 a 1 of the display unit side body 52, and the compression coil spring 73 constitute the lock mechanism 70. The bearing portion 71a of the lock member 71, the arm portions 71b and 71c extending from the bearing portion 71a on both sides, and the lock release button 56 at the tip of the arm portion 71c constitute a lock release operation mechanism 77.

  Next, the hinge 53 will be described.

As shown in FIGS. 6, 9, 10, and 11, the housing main body 65 of the display unit side body 52 has a cylindrical portion 65 a, a semi-cylindrical portion 65 b, and a cut portion in order from the X2 direction end side to the X1 direction. It has a notch portion 65c and a cylindrical portion 65d. The housing main body 62 of the operation key side casing 51 has an overhanging portion 54y1, a cutout portion 62a, a semi-cylindrical portion 62b, a cutout portion 62c, and a cover portion 55 of the cover portion 54 in order from the X2 direction end side to the X1 direction. The overhang portion 55y1. The cylindrical portion 65a and the semicylindrical portion 65b are fitted into the cutout portion 62a, the semicylindrical portion 62b is fitted into the cutout portion 65c, and the cylindrical portion 65d is fitted into the cutout portion 62c. Further, the semi-cylindrical portion 66a of the cover 66 is opposed to the semi-cylindrical portion 65b to form the combined cylindrical portion 80, and the semi-cylindrical portion 63a of the cover 63 is opposed to the semi-cylindrical portion 62b to form the combined cylindrical portion 81. The combination cylindrical portion 80 and the combination cylindrical portion 81 are adjacent to and communicate with each other.
A shaft member 82 and a torsion coil spring 83 are fitted in the cylindrical portion 65a. The square shaft portion 82a of the shaft member 82 is fitted into the square hole 54c of the projecting portion 54y1 and is prevented from rotating. The torsion coil spring 83 is fitted in the shaft member 82 and is accommodated in the cylindrical portion 65a, the end portion 83a on the X2 direction side is locked to the shaft member 82, and the end portion 83b on the X1 direction side is X1. It is engaged with the inside of the cylindrical portion 65a in a state of being twisted clockwise as viewed in the direction. An E-shaped retaining ring 84 is fitted and fixed to the distal end side of the square shaft portion 82a, and a cap 85 is fitted and fixed to the opening 54d of the overhang portion 54y1.

  A cylindrical damper unit 86 is incorporated in the cylindrical portion 65d. The case 86a of the damper unit 86 is fixed to the cylindrical portion 65d. The square shaft portion 86b of the damper unit 86 is fitted into the square hole 55b of the overhang portion 55y1 and is prevented from rotating. An E-shaped retaining ring 87 is fitted and fixed to the distal end side of the rectangular shaft portion 86a, and a cap 88 is fitted to the opening 55c of the overhang portion 55y1.

  When the cellular phone 50 is folded as shown in FIGS. 2A and 3, the torsion coil spring 83 is twisted, and the display unit side body 52 is twisted. The coil spring 83 is biased in the A1 direction with respect to the operation key side casing 51 by the torsion spring force. Therefore, when the lock release button 56 is pressed to release the lock, the display unit side body 52 is rotated in the A1 direction by the restoring force of the torsion spring of the torsion coil spring 83. At this time, the display unit side body 52 rises slowly due to the action of the damper unit 86, and the impact when the final state shown in FIG.

  A coaxial flexible cable 100 having a coaxial cable structure passes through the hinge 53. As shown in FIGS. 6, 9, 10 (D), and 11 (A), one end of the flexible cable 100 is connected to the connector 78 on the printed circuit board 67 in the display unit side body 52, The other end is connected to a connector 79 on the printed circuit board 64 in the operation key side casing 51 through the hinge 53. Thereby, the printed circuit board 67 in the display unit side body 52 and the printed circuit board 64 in the operation key side body 51 are electrically connected.

  At the position of the hinge 53, the flexible cable 100 forms a loop 101 of 360 degrees in the counterclockwise direction when viewed from the X2 side from the display unit side case 52 side toward the operation key side case 51. The loop 101 is accommodated inside the adjacent combination cylindrical portions 80 and 81. The portion of the flexible cable 100 forming the loop 101 urges the turning force in the A1 direction to open the display unit side housing 52 with respect to the operation key side housing 51 by the elastic force of the flexible cable 90 itself. . That is. The flexible cable 100 incorporated so as to form the loop 101 at the hinge 53 functions to assist the torsion spring force of the torsion coil spring 83.

  Therefore, as the torsion coil spring 83, a torsion spring force is used which is less than the usual case by the amount of rotational power obtained by the flexible cable 100 incorporated as described above.

  Next, the coaxial flexible cable 100 will be described.

  12, 13 and 14 show the structure of the coaxial flexible cable 100. FIG.
