Description

  TECHNICAL FIELD The present invention relates to an electronic device casing packing, a case structure, and an electronic device, and more specifically, an electronic device that can prevent a reduction in size and a reduction in design freedom caused by a packing that waterproofs the case. The present invention relates to packing for equipment casings, case structures, and electronic equipment.

  In the electronic device, the case is divided into a plurality of case parts for the purpose of opening / closing the inside of the case when various components are mounted inside the case. In addition, an operation port of a part to be operated at the time of use is opened on the outer surface of the case and opened / closed with a cap part. In order to provide this case with a waterproof function, waterproofness and dustproofness are ensured by interposing packings between the case parts and between the operation opening and the cap parts.

  However, in the case of an electronic device, if packing is interposed at each divided part of the case parts, the packing overlaps in the parallel direction and the size increases, and the number of parts increases, resulting in poor workability. There was a problem. For example, as shown in FIG. 5, in the case of a mobile phone that connects the operation housing case 101 and the display housing case 102 so as to be openable and closable, the front case part 103 is attached to the short side surface 101 c of the operation housing case 101. Edge portions 103a and 104a of the divided part of the rear case part 104 are formed and a rubber case packing 105 is sandwiched to ensure waterproofness and dustproofness. Further, a connector opening (cap part) 109 for closing the connector opening 108 is opened on the short side surface 101c of the connector for external connection 107 mounted on the printed wiring board 106. The cap packing 110 is sandwiched between them to ensure waterproofness and dustproofness. In this case, as shown in FIG. 6, one case packing 105 and two cap packings 110 are overlapped in the height direction of the short side surface 101 and become thick, and the number of parts increases, so that management and assembly work are performed. Becomes complicated.

In order to solve this problem, for example, Patent Document 1 proposes that the case packing and the cap packing are integrated to avoid an increase in the number of parts and an increase in size.
Japanese Utility Model Publication No. 04-020268

  However, in the structure described in Patent Document 1, even when applied to the mobile phone shown in FIGS. 5 and 6, a part of the case packing 105 and a part of the cap packing 110 are integrated in common. Only. In other words, it is only possible to avoid an increase in the thickness of the electronic device by eliminating the case packing 105 and the cap packing 110 from overlapping each other. That is, since the connector opening 108 opened and closed by the connector cap 109 exists in the short side surface 101c together with the edges 103a and 104a of the front case part 103 and the rear case part 104, the edge 103a through which the case packing 105 is interposed. , 104a must be brought close to one side of the short side surface 101c. Then, there is a problem that the outer surface on the end side of the short side surface 101c of the operation casing case 101 must be formed in an angular shape, and the degree of freedom in design is limited.

  This problem does not require the case packing to be sandwiched between the edge parts of the case parts.In other words, the problem also occurs in electronic devices that do not have a waterproof / dustproof function. The importance of miniaturization and design for electronic devices has become apparent along with the demand for waterproof and dustproof functions.

  The present invention has been made in view of the above-mentioned circumstances. Even in the case of a structure that requires a case packing and a cap packing in the same plane, it is possible to realize downsizing and at the same time limit the freedom of design. It is an object of the present invention to provide an electronic device casing packing and case structure that can be avoided, and an electronic device.

  In order to solve the above-described problem, the configuration of the present invention is arranged in at least one region of an annular case packing interposed between the first case part and the second case part constituting the electronic device casing. An annular cap packing interposed between an opening formed across the first case part and the second case part and a cap that detachably covers the opening is formed in the region. It is characterized by being erected integrally in a manner straddling a virtual straight line connecting both ends.

  According to the configuration of the present invention, the cap packing can be integrally formed in a shape straddling both sides in the extending direction of the case packing, and the opening covered with the cap is the edge of the first and second case parts. It can be formed in an opening shape straddling both sides in the extending direction. Therefore, it is possible to easily promote downsizing by avoiding the case packing and the cap packing from overlapping and bulky, and the edges of the first and second case parts that face each other are provided. The degree of freedom in case design can be improved by avoiding being brought to the corner of the case.

The first case part and the second case part are arranged in at least one region of an annular case packing interposed between the first case part and the second case part constituting the electronic device casing. An annular cap packing that is inserted between an opening formed across the opening and a cap that detachably covers the opening is branched from the end of the region of the case packing, and both ends of the region Are integrally erected in a manner straddling a virtual straight line connecting the two.
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

The display housing case 12 is divided into a box-shaped front case part 23 and a rear case part 24 having substantially the same depth by dividing a substantially central one circumference in the thickness direction of the short side surface 12c vertically. . As a result, the display housing case 12 is a print in which various parts are mounted inside by separating / fitting the edge portions 23a and 24a of the front case part 23 and the rear case part 24 that go around the short side surface 12c. The wiring board 26 can be opened / closed so as to be mounted.

  The operation housing case 11 and the display housing case 12 are connected to printed wiring boards 25 and 26 mounted therein via a flexible wiring board 27. The hinge part 13 is connected to the center of the hinge case 13a connected to both sides of the end part of the front case part 21 of the operation casing case 11 and the end part of the front case part 23 of the display casing case 12. The hinge cylinder 13b is connected in a continuous state, and is constructed by incorporating a hinge unit 16 and a cylindrical part 17 having an English letter C cross section. The hinge cylinder 13b of the hinge portion 13 is formed with a semicircular opening portion 13c that opens on the lower side. The semicircular opening portion 13c is formed in a semicircular shape that is connected to the end portion of the rear case part 24. The portion 13d is fitted and closed. The flexible wiring board 27 enters the inside of the operation housing case 11 and the display housing case 12 through the inside of the cylindrical part 17 having a C-shaped cross section, and electrically connects the printed wiring boards 25 and 26.

  Further, the operation housing case 11 has a battery opening 29 for housing the battery 28 in the rear case part 22, and the battery opening 29 is closed by fitting the battery cover 31. It is like that.

  The operation housing case 11 and the display housing case 12 are made of an elastic member having a waterproof property such as a rubber material or a resin material on the edge portions 21a to 24a of the front case parts 21 and 23 and the rear case parts 22 and 24. The case packings 32 and 33 are fitted in a state of being sandwiched, thereby closing the gaps between the cases and providing a waterproof function. Further, the battery opening portion 29 of the operation housing case 11 is provided with a waterproof function by closing and fitting the battery packing 34 between the battery cover 31 and the battery cover 31. In addition, the case packings 32 and 33 ensure waterproof performance by integrally molding the flexible wiring board 27 at the connection portion between the operation housing case 11 and the display housing case 12.

  The operation housing case 11 is mounted with an external connection connector (component) 35 to which the printed wiring board 25 mounted inside is externally connected, and a connection operation to the external connection connector 35 can be performed. Thus, a connector opening 36 that is exposed to the outside is formed. The connector opening 36 is closed by fitting a connector cap (cap part) 37. Here, the connector opening 36 that is opened to expose the external connection connector 35 to the outside will be described as an example. However, the present invention is not limited to this. For example, an external component such as an IC card is inserted and mounted. The present invention can also be applied to an opening that opens.

  By the way, the operation casing case 11 is bent at the position where the connector opening 36 is formed by bending the edges 21a and 22a of the front case part 21 and the rear case part 22 continuously away from each other. The opening 36 is formed so as to open. In other words, the front case part 21 and the rear case part 22 have half openings 38 and 39 symmetrically opened on both sides with respect to the extended line (virtual straight line) of the edges 21a and 22a, and are connected so as to straddle both sides. Opening 36 is formed.

  On the other hand, the case packing 32 is also branched along the peripheral edges 38a and 39a of the half openings 38 and 39 of the front case part 21 and the rear case part 22 at the position where the connector opening 36 is formed. By being bent in the direction of separation (expansion), it is integrally provided so as to straddle the region where the connector opening 36 is formed. That is, the case packing 32 branches off from the main body portion sandwiched between the edge portions 21a and 22a of the front case part 21 and the rear case part 22, and the branch portions 32a and 32b function as cap packing. As a result, the connector opening 36 is opened without obstruction by the case packing 32, and the branch portions 32 a and 32 b of the case packing 32 are connected to the peripheral portions 38 a and 39 a of the half openings 38 and 39 and the connector cap 37. The waterproofing performance is ensured by being sandwiched between the peripheral edge portion 37a.

The opening 36 (half opening 38, 39) can be opened and opened / closed by the connector cap 37. Therefore, in the operation casing case 11, the edge portions 21a and 22a of the front case part 21 and the rear case part 22 can be formed in the center in the height direction of the short side surface 11c. Note that a straight line L adjacent to the connector cap 37 in FIG. 3 indicates the formation positions of the edges 21 a and 22 a of the front case part 21 and the rear case part 22.

  The operation casing case 11 has a case packing 32 sandwiched between the edge portions 21 a and 22 a of the front case part 21 and the rear case part 22 to ensure waterproofness. At the same time, the waterproofness at the peripheral edge portion 37a of the connector cap 37 is ensured by sandwiching the branch portions (cap packing) 32a, 32b of the case packing 32 between the peripheral edge portions 38a, 39a continuous with the edge portions 21a, 22a. can do. Therefore, in this operation housing case 11, only one part of the case packing 32 can be used to avoid unnecessary overlapping of the packing on the short side surface 11c side, and the cap packing is managed and attached as a separate part. Costs can be reduced without this.

  Thus, according to this embodiment, the semi-opening portions 38 and 39 (peripheral portions 38a and 39a) are continuous to the edge portions 21a and 22a of the front case part 21 and the rear case part 22 of the operation casing case 11. By forming, the connector opening 36 can be opened at the center of the short side surface 11c. At the same time, it is possible to provide a function as a cap packing by integrally molding the branch portions 32a and 32b branched from the case packing 32 for waterproofing between the edge portions 21a and 22a of the front case part 21 and the rear case part 22. it can. Therefore, in the operation housing case 11, the packing is not overlapped and bulky, and can be further reduced in size and thickness, and the boundary between the short side surface 11c and the arrangement surface 11a or the back surface 11b (the end of the short side surface 11c). The edge portions 21a and 22a of the front case part 21 and the rear case part 22 can be separated from the side) and designed in a free shape.

  As another aspect of this embodiment, as shown in FIG. 4, the outer surface of the boundary portion between the short side surface 11c of the front case part 21 and the rear case part 22 and the arrangement surface 11a or the back surface 11b is formed in a curved shape. You can design freely, such as rounding.
