Description

  The present invention relates to a slide type mobile terminal in which one housing slides with respect to the other housing.

  A slide-type mobile terminal is a mobile terminal such as a mobile phone that can slide one housing with respect to the other housing. 6A and 6B are perspective views illustrating an example of a slide type mobile terminal. FIG. 6A illustrates a slide type mobile terminal in a closed state, and FIG. 6B illustrates a slide type mobile terminal in an open state.

  In the slide-type portable terminal shown in FIG. 6, the circuit boards in the respective housings are electrically connected by a flexible flat cable (hereinafter referred to as “flexible cable”). 7 is a cross-sectional view of the slide-type mobile terminal shown in FIG. 6, FIG. 7A shows a cross-section of the slide-type mobile terminal in the closed state, and FIG. 7B shows a slide-type mobile terminal in the open state. The cross section of is shown. The surface on which the upper housing 10 slides with respect to the lower housing 20, that is, the rear surface of the upper housing 10, and the surface on which the lower housing 20 slides with respect to the upper housing 10, that is, the front surface of the lower housing 20. Each has an opening. The flexible cable 30 is connected to the circuit board of each housing through these openings.

  When this slide type portable terminal is changed from the closed state shown in FIG. 7A to the open state shown in FIG. 7B, an extra length portion is generated in the flexible cable 30. However, when the slide type mobile terminal is in the open state, the positions of the openings coincide with each other, and a space 40 indicated by a dotted line in FIG. 7B is formed. The extra length of the flexible cable 30 in the open state is accommodated in the space 40.

  As illustrated in FIG. 7, an operation unit 21 such as a button is provided in a portion that does not overlap the upper housing 10 in the open state of the front surface of the lower housing 20, but the operation unit 21 is provided on a surface that overlaps the upper housing 10. Cannot be provided. Therefore, in view of the function of the mobile terminal, it is preferable that the area where the upper casing 10 and the lower casing 20 overlap is smaller.

  However, in the slide-type mobile terminal shown in FIG. 7, when the area where the upper housing 10 and the lower housing 20 overlap in the open state is reduced, the flexible cable 30 is exposed from the opening provided in the upper housing 10. End up. For this reason, in order to make the said overlapping area small, it is necessary to make the opening part provided in both housings small.

  FIG. 8 is a cross-sectional view of the slide type mobile terminal in the closed state (a) and the open state (b) when the opening shown in FIG. 7 is reduced. If the opening is reduced, the area where the upper housing 10 and the lower housing 20 overlap in the open state can be reduced as shown in FIG. 8B, but the space 41 indicated by the dotted line in FIG. It becomes small and the extra length part of the flexible cable 30 also becomes long. For this reason, the extra length portion of the flexible cable 30 does not fit in the space 41. In order to accommodate the extra length of the flexible cable 30 in the space, the space 41 must be expanded. However, in this case, since the casing needs to be thick, the size of the mobile terminal itself increases.

  An object of the present invention is to provide a slide type that can be accommodated in a casing without the extra length of the flexible cable being exposed to the outside, even in a long slide type portable terminal in which the upper casing and the lower casing overlap in a small open area.

Electrically connected by 301. The flexible cable 301 corresponds to a “connecting portion” in claims. Each housing is provided with an opening, and the flexible cable 301 is connected to the circuit board of each housing through the opening. The opening 103 of the upper housing 100 is provided on the surface facing the lower housing 200 of the upper housing 100, that is, on the bottom surface side of the back surface of the upper housing 100. on the other hand. The opening 203 of the lower housing 200 is provided on the surface facing the upper housing 100 of the lower housing 200, that is, on the upper surface side of the front surface of the lower housing 200. In addition, the opening part of each housing | casing is provided in the position which overlaps when a slide type | mold portable terminal is an open state and leaves | separates most when it is a closed state.

  As shown in FIGS. 1 and 2, the flexible cable 301 passes from the circuit board 201 of the lower casing 200 through the opening 203 of the lower casing 200 and passes through the gap between the lower casing 200 and the upper casing 100. Then, it passes through the opening 103 of the upper casing 100 and reaches the circuit board 101 of the upper casing 100. More specifically, the flexible cable 301 connected on the circuit board 201 of the lower casing 200 is a sliding direction of the upper casing 100 with respect to the lower casing 200 when the slide type mobile terminal transitions from the closed state to the open state. (Hereinafter simply referred to as the “opening direction”), and then folded back within the lower casing 200, passes through the opening 203 of the lower casing 200, and opens a gap between the lower casing 200 and the upper casing 100. It extends in the direction opposite to the opening direction (the closing direction). Further, the flexible cable 301 passes through the opening 103 of the upper casing 100 from the gap between the lower casing 200 and the upper casing 100, is folded back in the upper casing 100, and opens in the upper casing 100 in the opening direction. After extending and then being folded back again, it is connected to the circuit board 101 of the upper casing 100.

  As described above, the flexible cable 301 according to the present embodiment is provided with curved portions in the vicinity of the opening 203 of the lower housing 200, in the vicinity of the opening 103 of the upper housing 100, and at three locations in the upper housing 100. In the following description, the curved portion near the opening 203 of the lower housing 200 is referred to as a “first curved portion”, the curved portion near the opening 103 of the upper housing 100 is referred to as a “second curved portion 151”, and the upper housing. The bending portion in the body 100 is referred to as a “third bending portion”. The second bending portion 151 corresponds to a “curving portion” in the claims.

  Hereinafter, with reference to FIG. 1, the movement of the flexible cable 301 when the slide type mobile terminal according to the present embodiment shifts from the closed state to the open state will be described. When the slide type mobile terminal of the present embodiment is in the closed state shown in FIG. 1A, when the user of the terminal slides the upper casing 100 in the opening direction, as shown in FIG. The inner wall surface 105 at the bottom of 100 pushes the outer peripheral surface of the second bending portion 151 in the opening direction. At the same time, the third bending portion moves in the opening direction within the upper housing 100. At the time of sliding in the opening direction or in the open state, a part of the flexible cable 301 generated by the extra length portion 153 of the flexible cable 301 generated by the sliding is in the upper casing 100 indicated by a dotted line in FIG. Fits in the storage unit 109. Note that the length B in the sliding direction of the storage portion 109 shown in FIG. 2C is half of the length A of the extra length portion of the flexible cable 301 that is generated when the storage portion 109 is not high. The above is preferable. However, if the height of the storage portion 109 is sufficient, even if the length B in the sliding direction is less than half of the length A of the extra length portion, a part of the flexible cable 301 generated by the extra length portion 153 is accommodated. Stored in the unit 109.

  FIG. 3 is an enlarged view of a portion indicated by a one-dot chain line in FIG. As described above, since the outer peripheral surface of the second bending portion 151 is pushed by the inner wall surface 105 of the bottom of the upper housing 100 when the slide type mobile terminal of the present embodiment shifts from the closed state to the open state, The third bending portion moves in the opening direction within the upper housing 100. In the present embodiment, the inner wall surface 105 at the bottom of the upper housing 100 is the vertex of the outer peripheral surface of the second bending portion 151 as shown in FIG. 3A or the vertex as shown in FIG. In order to come into contact with the outer peripheral surface of the second bending portion 151 at a point closer to the lower housing 200, the extra length portion 153 of the flexible cable 301 is sequentially sent out toward the storage portion 109. Conversely, when the inner wall surface 105 at the bottom of the upper housing 100 comes into contact with the outer peripheral surface of the second curved portion 151 above the vertex of the outer peripheral surface of the second curved portion 151, the extra length portion 153 of the flexible cable 301 is Since it sends out toward the clearance gap between the upper housing | casing 100 and the lower housing | casing 200, it is unpreferable. A part of the inner wall surface 105 that comes into contact with the outer peripheral surface of the second bending portion 151 when the slide type mobile terminal of the present embodiment shifts from the closed state to the open state is referred to as the “outer peripheral contact portion” in the claims. It corresponds to.

  Next, with reference to FIG. 2, the movement of the flexible cable 301 when the slide type mobile terminal of this embodiment shifts from the open state to the closed state will be described. When the slide type mobile terminal of the present embodiment is in the open state shown in FIG. 2A, the user of the terminal slides the upper housing 100 in the direction opposite to the open direction (hereinafter referred to as “closed direction”). As shown in FIG. 2B, an inner peripheral contact portion 107 which is an end portion on the back surface of the upper housing 100 and forms a part of an end of the opening 103 of the upper housing 100 is a second bending portion 151. Push the inner circumferential surface of in the closing direction. At the same time, the third bending portion moves in the closing direction in the upper housing 100, and the flexible cable 301 stored in the storage portion 109 is pulled out.

  Note that the inner peripheral contact portion 107 that contacts the inner peripheral surface of the second bending portion 151 when sliding in the closing direction is curved toward the inner peripheral surface side so as not to damage the flexible cable 301. Moreover, you may attach a curved part to the inner periphery contact part 107 as another form.

  In the slide-type mobile terminal according to the present embodiment described above, a part of the flexible cable 301 and each casing are rubbed against each other when sliding in the opening direction and in the closing direction. For this reason, it is preferable that the surface of the portions 501, 503, 505, and 507 shown in dotted lines in FIG. 4 that are in contact with the flexible cable 301 is processed with a material having a small friction coefficient. On the other hand, it is preferable that a portion of the portion 511 that is in contact with the flexible cable 301 shown by a one-dot chain line in FIG. 4 is surface-treated with a material having a large friction coefficient.

  As described above, in this embodiment, a part of the flexible cable 301 generated by the extra length portion 153 of the flexible cable 301 generated when the slide type mobile terminal is slid in the open direction or in the open state is in the open state. At this time, it is housed in a folded state in the housing portion 109 in the upper housing 100, not in a space formed by matching the positions of the openings of the housings. Therefore, the size of the opening of each housing can be reduced. If the size of the opening is small, the overlapping area in the open state can be reduced, and the flexible cable 301 is not exposed to the outside. For this reason, it is possible to realize a long slide type mobile terminal in which the size of the mobile terminal itself remains the same and the area where the upper housing and the lower housing overlap in a opened state is small.

  In the present embodiment, the opening of each housing is provided at the most distant position in the closed state. However, if the slide length is somewhat sacrificed, the opening may not be provided at the most distant position. good. That is, the opening 103 of the upper housing 100 or the opening 203 of the lower housing 200 may be provided near the center of the slide surface.

  If a long slide type portable terminal can be realized, as shown in FIG. 5, the possibility of realizing a portable terminal that can be held in an open state with the upper case upright with respect to the lower case increases.

  The slide type portable terminal according to the present invention is useful as a long slide type portable terminal having a small area where the first casing and the second casing overlap in the open state.
