1. Configuration of Electronic Device FIG. 1 is a perspective view of a mobile phone 1 as an electronic device including a sealing member 10 according to an embodiment of the present invention. FIG. 2 is a perspective view showing a state in which the cellular phone 1 shown in FIG. 1 is folded. 1 and 2, the insertion member 5 and the sealing member 10 provided in the mobile phone 1 are indicated by dotted lines.

  The mobile phone 1 has a first housing 2 and a second housing 3. The mobile phone 1 is configured as a so-called folding-type mobile phone in which a first housing 2 and a second housing 3 are rotatably connected by a connecting portion 4. One end side of the insertion member 5 passes through the opening provided in the first housing 2 and is inserted into the first housing 2, and the other end passes through the opening provided in the second housing 3. The second housing 3 is inserted. Further, the insertion member 5 passes through the inside of the connecting portion 4 and is connected to the substrate located inside the first housing 2 and the substrate located in the second housing 3, respectively. The insertion member 5 is equipped with sealing members 10 on the first housing 2 side and the second housing 3 side, respectively. The sealing member 10 is mounted so as to close the opening provided in the first housing 2 and the opening provided in the second housing 3.

  FIG. 3 is a perspective view showing the insertion member 5 to which the sealing member 10 is attached.

  As the insertion member 5, for example, a flexible printed circuit board (FPC) can be used. Since the FPC is a flexible wiring material that can follow the folding operation of the mobile phone 1, the FPC is used to link the first casing 2 and the second casing 3. In the present embodiment, the insertion member 5 is a band-shaped FPC and includes connectors 6 at both ends thereof. When the sealing member 10 is mounted so as to sandwich the insertion member 5, the insertion member 5 is inserted into the sealing member 10.

2. Configuration of Sealing Member FIG. 4 is an enlarged perspective view showing the region indicated by A for the sealing member 10 and the insertion member 5 of FIG. FIG. 5 is a perspective view showing a state in which the sealing member 10 of FIG. 4 is opened to be attached to the insertion member 5. FIG. 6 is a front view when viewed in the penetration direction of the insertion member 5 in a state where the sealing member 10 is opened. FIG. 7 is a front view showing a state in which the sealing member 10 of FIG. 6 is closed. FIG. 8 is a side view of the sealing member 10 of FIG. FIG. 9 is a bottom view of the sealing member 10 of FIG. FIG. 10 is a cross-sectional view of the sealing member 10 of FIG. 7 taken along line BB. FIG. 11 is a cross-sectional view of the sealing member 10 into which the insertion member 5 is inserted, taken along line CC in FIG. In addition, about a rear view, since it becomes substantially left-right symmetrical with a front view, illustration is abbreviate | omitted. Since the left side view, right side view, bottom view and plan view are substantially symmetrical, only one of them is shown.

  The sealing member 10 seals the openings provided in the first casing 2 and the second casing 3 in order to insert the insertion member 5, so that the first casing 2 or the second casing 3 It is a member that prevents water, dust or other foreign matter from entering inside. The sealing member 10 has a first mounting member 11 and a second mounting member 21. The first mounting member 11 and the second mounting member 21 have substantially the same form as each other, and are members that can be attached to and detached from the insertion member 5 with the insertion member 5 interposed therebetween. As shown in FIG. 11, the first mounting member 11 and the second mounting member 21 are connected by a connecting member 22. The first mounting member 11 and the second mounting member 21 are opened and closed with the connection member 22 as a fulcrum. The connecting member 22 biases the first mounting member 11 and the second mounting member 21 in the direction in which the insertion member 5 is sandwiched. Therefore, when the user opens the sealing member 10, disposes the insertion member 5 at a predetermined location, and releases the force to the sealing member 10, the sealing member 10 is the first component. The mounting member 11 and the second mounting member 21 are driven to close each other, and as a result, the insertion member 5 can be clamped.

  Further, the sealing member 10 is inserted into the first casing 2 or the second casing 3 in a direction in which the first mounting member 11 and the second mounting member 21 are pressed against each other from the inner wall thereof. A clamping pressure is applied. Therefore, the first mounting member 11 and the second mounting member 21 are held in a state where the insertion member 5 is sandwiched.

  The sealing member 10 has an elastic body 12 as a first seal member. As shown in FIG. 10, the first mounting member 11 and the second mounting member 21 have grooves 14 and 24, respectively, into which the elastic bodies 12 are fitted, respectively. The depth of the groove 14 and the groove 24 is smaller than each diameter of the elastic body 12. For this reason, in a state where the elastic body 12 is fitted into the first mounting member 11 and the second mounting member 21, respectively, the elastic body 12 protrudes toward the first housing 2 and the second housing 3 side. . When the inner wall of the first casing 2 or the second casing 3 holds the sealing member 10, the elastic body 12 follows the unevenness of the inner wall of the first casing 2 or the second casing 3. Can be deformed and closely adhered, which contributes to enhancing the sealing effect. Further, in order to improve the handleability, the elastic body 12 is fixed to the first mounting member 11 in the groove 14 and is fixed to the second mounting member 21 in the groove 24.

  Further, the first mounting member 11 and the second mounting member 21 have a seal part 13 and a seal part 23 as second seal members, respectively. The seal portion 13 and the seal portion 23 are provided on the inner surface of the opening / closing port when the first mounting member 11 and the second mounting member 21 are opened and closed. Specifically, the seal portion 13 and the seal portion 23 are formed on the surface in contact with the insertion member 5 and its surroundings when the first attachment member 11 and the second attachment member 21 are attached to the insertion member 5. The first mounting member 11 and the second mounting member 21 are disposed on opposite surfaces of the first mounting member 11 and the second mounting member 21.

  The first mounting member 11 and the second mounting member 21 are made of, for example, a resin such as polycarbonate, acrylic, ABS (acrylonitrile-butadiene-styrene copolymer resin), polyamide, urethane, or a mixture thereof. It is preferable that the first mounting member 11 and the second mounting member 21 are made of a material having rigidity higher than the hardness of the seal portion 13, the seal portion 23, and the elastic body 12. In such a case, the first mounting member 11 and the second mounting member 21 can withstand the pressure applied when the first mounting member 11 and the second mounting member 21 are incorporated into the first casing 2 or the second casing 3 and have a predetermined arrangement. Can be securely locked in place. Further, the first mounting member 11 and the second mounting member 21 are members having a small dimensional difference between before and after molding and high dimensional accuracy, and having a shape or the like at the time of manufacture or use. It is preferable to be composed of a member that changes little.

  The elastic body 12 as the first seal member has a gap between each outer periphery of the first mounting member 11 and the second mounting member 21 and each inner surface of the first casing 2 and the second casing 3. It is a member for sealing. The elastic body 12 is provided along each outer periphery from the opening side when the first mounting member 11 and the second mounting member 21 are opened and closed. When the first mounting member 11 and the second mounting member 21 are mounted on the insertion member 5, both ends of the elastic body 12 are connected to each other to form a single ring that surrounds them. The ring formed by the elastic body 12 is provided on the outer periphery of the sealing member 10 with the insertion member 5 as an axis.

  The elastic body 12 is preferably made of a flexible resin or elastomer. By configuring the elastic body 12 from a flexible resin or elastomer, the elastic body 12 is configured so that the inner surface of the first casing 2 or the second casing 3 and the first mounting member 11 or the second mounting member 21 It can be easily deformed to fill the gap. For this reason, the sealing effect can be enhanced. The elastic body 12 is preferably mainly formed from urethane rubber, acrylic rubber, silicone rubber or the like having a Shore A hardness of 40 to 70 degrees, for example. Among these, it is more preferable to use silicone rubber having high durability or a composite product thereof. The length by which the elastic body 12 protrudes from the outer periphery of the first mounting member 11 and the second mounting member 21 can be changed depending on the hardness of the elastic body to be used. Can do. When the protruding length of the elastic body 12 is 1 mm or more, the elastic body 12 is in contact with the first housing 2 and the second housing 3 and is compressed and fixed by the first housing 2 or the second housing 3. In this case, the elastic body 12 is easily deformed and can absorb variations in dimensions of the respective housings. Therefore, a gap is hardly generated between the elastic body 12 and the first and second casings 2 and 3. On the other hand, when the protruding length of the elastic body 12 is 2 mm or less, even when used for a long period of time, the sealing performance is lowered due to a reduction in the elastic force of the elastic body 12 or the elastic body 12 itself is deformed. The effect of lowering can be reduced. Further, by making the protruding length of the elastic body 12 within 2 mm, the compression applied to the elastic body 12 when the elastic body 12 is compressed and fixed by the first housing 2 and the second housing 3. Since the load does not become too large, the first casing 2 or the second casing 3 is not easily deformed or damaged.

  The seal portion 13 and the seal portion 23 as the second seal member are provided between the first mounting member 11 and the insertion member 5, between the second mounting member 21 and the insertion member 5, and the first This is a member for sealing between the mounting member 11 and the second mounting member 21 so as not to generate a gap around the insertion member 5. The seal portion 13 and the seal portion 23 are provided between the first mounting member 11 and the second mounting member 21 in a state where the sealing member 10 is mounted on the insertion member 5. Therefore, the seal portion 13 and the seal portion 23 can be sufficiently in close contact with the insert member 5 at a portion where the seal portion 13 and the seal portion 23 are in contact with the insert member 5. Further, even at the portion where the seal portion 13 and the seal portion 23 are in contact, the seal portion 13 and the seal portion 23 can sufficiently adhere to each other. Of the seal part 13 and the seal part 23, only one of the seal part 13 and the seal part 23 may be provided as a part that does not contact the insertion member 5. Moreover, it is preferable that the part which does not contact the insertion member 5 among the seal part 13 and the seal part 23 protrudes in the insertion member 5 side rather than the part which contacts the insertion member 5. This means that, of the seal portion 13 and the seal portion 23, the region in contact with the insertion member 5 is recessed inwardly from the other regions.

  The seal portion 13 and the seal portion 23 are preferably made of a flexible resin or elastomer. By configuring the seal portion 13 and the seal portion 23 from a flexible resin or elastomer, the seal portion 13 and the seal portion 23 are easily deformed according to the unevenness on the surface of the insertion member 5, and the surface having the unevenness It can adhere. The seal part 13 and the seal part 23 are preferably made of urethane rubber, acrylic rubber, silicone rubber or the like having a Shore A hardness of 20 to 50 degrees, for example. The Shore A hardness of the seal portion 13 and the seal portion 23 is preferably smaller than the Shore A hardness of the elastic body 12. As described above, by adjusting the hardness of the elastic body 12 and the seal portions 13 and 23, the adhesion between the seal portion 13 and the seal portion 23 and the insertion member 5 can be improved, and the dimensional accuracy of the elastic body 12 can be secured. Further, when the seal portion 13 and the seal portion 21 are mainly made of silicone resin, the first mounting member 11 and the second mounting member 21 are fixed to the seal portion 13 and the seal portion 21 in order to fix the first mounting member 11 and the second mounting member 21. The mounting member 11 and the second mounting member 21 are preferably made of polycarbonate, acrylic, polyamide, or urethane resin.

  As shown in FIG. 11, the connection member 22 is preferably embedded in the first mounting member 11 and the second mounting member 21, and the first mounting member 11 and the second mounting member 21 are connected to each other. Connecting. The connecting member 22 is, for example, a so-called U-shaped clip formed continuously from two plate-like portions extending substantially in parallel and a curved portion connecting them. The two plate-like portions of the connection member 22 are embedded in the first mounting member 11 and the second mounting member 21 in a direction that sandwiches the insertion member 5. The curved portion of the connection member 22 is located at the end of the contact surface between the first mounting member 11 and the second mounting member 21. Therefore, the first mounting member 11 and the second mounting member 21 rotate around the curved portion of the connecting member 22 as a fulcrum, so that the end of the connecting member 22 opposite to the curved portion The first mounting member 11 and the second mounting member 21 can be opened and closed.

  The insertion member 5 can be disposed between the first mounting member 11 and the second mounting member 21 by opening the first mounting member 11 and the second mounting member 21. It is. Further, when the user stops applying the force for opening the first mounting member 11 and the second mounting member 21 to the sealing member 10, due to the restoring force of the connecting member 22, The first mounting member 11 and the second mounting member 21 are biased in the direction in which the insertion member 5 is sandwiched. Since the first mounting member 11 and the second mounting member 21 are given a clamping force by the connection member 22, or between the first mounting member 11 and the second mounting member 21, or The contact state between the insertion member 5 and the first mounting member 11 or the second mounting member 21 can be maintained.

  In the sealing member 10 having the above-described configuration, it is not necessary to apply heat or pressure more than necessary when the sealing member 10 is attached to the insertion member 5. For this reason, damage or a deformation | transformation of the insertion member 5 can be prevented. Further, in the sealing member 10 as described above, the insertion member 5 and the sealing member 10 are not firmly fixed, so that the insertion member 5 and the sealing member 10 are firmly fixed by the tension on the insertion member 5. It is difficult for stress to occur in the portion, and breakage of the insertion member 5 can be prevented.

  Further, in the mobile phone 1 including the sealing member 10 as described above, it is possible to prevent foreign matters such as water and dust from entering the mobile phone 1. This is because the sealing member 10 seals the gap between the inner wall of the first casing 2 or the second casing 3 of the mobile phone 1 and the insertion member 5. In particular, the elastic body 12 of the sealing member 10 can seal the gap between the inner wall of the first casing 2 or the second casing 3 of the mobile phone 1 and the sealing member 10. Further, the seal portion 13 and the seal portion 23 can seal the gap between the sealing member 10 and the insertion member 5. In addition, since the absolute amount of dimensional change caused by the elastic body being held in the same shape for a long time is smaller than when all the sealing members 10 are formed of an elastic body, the elastic force is also reduced. Hard to occur.

  Further, in the sealing member 10 as described above, the connection member 22 can keep the first mounting member 11 and the second mounting member 21 in close contact with each other. Accordingly, the mobile phone 1 is connected between the first mounting member 11 and the second mounting member 21 or between the insertion member 5 and the first mounting member 11 or the second mounting member 21. It is possible to prevent foreign matters such as water and dust from entering the interior of the apparatus. Further, in the sealing member 10 as described above, the sealing member 10 is not easily dropped from the insertion member 5 by the connection member 22. In particular, even when the first casing 2 or the second casing 3 is deformed or disassembled, the sealing member 10 can be kept attached to the insertion member 5 alone.

3. Other Embodiments Although the sealing member 10 and the mobile phone 1 including the sealing member 10 according to the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made.

For example, the sealing member 10 may be employed in a PDA, portable computer, or other precision device.

  In the above-described embodiment, the mobile phone 1 has the first casing 2 and the second casing 3, but the present invention is not limited to such a configuration. The present invention can be used when the electronic apparatus has only one housing and an opening for inserting some member is provided in the housing. In addition, the electronic device of the present invention may be a slide type mobile phone (where the first housing 2 slides relative to the second housing 3) instead of the folding mobile phone 1.

  Moreover, in the above-mentioned embodiment, although the insertion member 5 is FPC, it is not restricted to such a form. The sealing member 10 can also be applied to the insertion member 5 other than the FPC. In such a case, each of the first mounting member 11 and the second mounting member 21 that comes into contact with the insertion member 5 is provided with a recess having a shape along the surface of the insertion member 5. Also good.

  In the above-described embodiment, the insertion member 5 is sandwiched between the first mounting member 11 and the second mounting member 21, but is not limited to such a configuration. For example, the insertion member 5 may be sandwiched between three or more mounting members.

  In the above-described embodiment, the sealing member 10 includes the connection member 22, but the connection member 22 is not essential. For example, the first mounting member 11 and the second mounting member 21 are formed as a single mounting member that can be opened and closed instead of being separated from each other, and the mounting member is provided with a cut as an opening / closing port. When the opening / closing port is provided so as not to divide the mounting member, the mounting member can be opened / closed using a portion where the opening / closing port is not provided as a fulcrum even if the connection member 22 is not provided. Further, when the user stops applying the force for opening the mounting member, the mounting member is biased in the direction of sandwiching the insertion member 5 by the restoring force of the mounting member. Even in such a case, the connection member 22 may be embedded in the mounting member for the purpose of increasing the urging force.

  In the above-described embodiment, the sealing member 10 is detachably attached to the insertion member 5, but is not limited to such a form. For example, once the sealing member 10 is attached to the insertion member 5, the sealing member 10 may be in a form that cannot be removed unless the sealing member 10 is destroyed.

  In the sealing member 10 according to the above-described embodiment, the first mounting member 11 and the second mounting member 21 have the same size and shape. Not limited. The first mounting member 11 and the second mounting member 21 may have different sizes or shapes. However, in order to make it difficult for foreign matter to enter, it is preferable that when the first mounting member 11 and the second mounting member 21 are joined, there are few irregularities in the outer peripheral portion where the elastic body 12 is disposed. . Furthermore, it is preferable that the sealing member 10 has a symmetrical shape with respect to the insertion member 5 as a central axis. In such a case, the sealing member 10 can uniformly adhere to the inner surface of the housing at any part of the elastic body 12, thus preventing foreign matter from entering uniformly from any part of the elastic body 12. be able to.

  In the above-described embodiment, the elastic body 12 is fixed to the first mounting member 11 by the groove 14 and further fixed to the second mounting member 21 by the groove 24. It is not limited to any form. The elastic body 12 may be configured to be able to fit into the first mounting member 11 and the second mounting member 21. However, from the viewpoint of facilitating attachment to the insertion member 5, it is preferable to integrate the first mounting member 11 and the second mounting member 21 and the elastic body 12.

  FIG. 12 is an exploded perspective view showing a state in which the sealing member 30 according to the modification of the present embodiment is attached to the insertion member 5. In addition, the same code | symbol is attached | subjected and demonstrated to the same element as the above-mentioned embodiment.

  In the above-described embodiment, the elastic body 12 constitutes one ring that surrounds the first mounting member 11 and the second mounting member 21 in a closed state. However, the first seal member is not limited to such a form. For example, as shown in FIG. 12, after the first mounting member 11 and the second mounting member 21 are mounted on the insertion member 5, the annular elastic body 32 is connected to the first mounting member 11 and the first mounting member 11. It may be a form that fits around the outer periphery of the two mounting members 21. In the case of this form, the elastic body 32 functions as a holding means for holding the close contact state between the first mounting member 11 and the second mounting member 21.

  In the above-described embodiment, the connection member 22 is biased in the direction in which the first mounting member 11 and the second mounting member 21 are closed. However, the present invention is not limited to this. For example, when the sealing members 10 and 30 are provided with holding means for keeping the first mounting member 11 and the second mounting member 21 sandwiching the insertion member 5, the connecting member 22. It is not necessary to energize. As the holding means, like the sealing member 30, the first seal member 32 may also serve as the holding means, or the sealing member 10 may further include another holding means. For example, the first mounting member 11 and the second mounting member 21 may be held so as not to be separated by a set of hook mechanisms as holding means. Further, the positions of the first mounting member 11 and the second mounting member 21 may be aligned by the hook mechanism.

  Further, the second mounting member 21 has a convex portion on the surface facing the first mounting member 11, and the concave portion is provided on the surface of the first mounting member 11 facing the convex portion. Good. In such a case, the first mounting member 11 and the second mounting member 21 can be easily aligned.

  In the above-described embodiment, the connection member 22 is a U-shaped member, but is not limited to such a form. For example, the connecting members 22 and 44 may be formed by bending one or more plate-shaped or bar-shaped members that can be elastically deformed, spirally, or coil spring-shaped.

  Further, in the above-described embodiment, the connection member 22 is entirely embedded in the first mounting member 11 and the second mounting member 21, but is not limited to such a form. For example, only a part of the connection member 22 may be embedded in the first mounting member 11 and the second mounting member 21. When the connection members 22 and 44 are coil spring shapes, the coil spring shape portion is not embedded in the first mounting member 11 and the second mounting member 21, and only the end of the coil spring is the first mounting portion. It is preferable that each of the mounting member 11 and the second mounting member 21 is embedded.

  FIG. 13 is a perspective view when the first mounting member 41 side of the sealing member according to the modification of the present embodiment is viewed from the surface side in contact with the insertion member 5. 14 is a perspective view when the second mounting member 42 side of the sealing member in FIG. 13 is viewed from the surface side in contact with the insertion member 5. FIG. 15 is a perspective view showing a state of the connecting member 22 when the first mounting member 41 of FIG. 13 and the second mounting member 42 of FIG. 14 are mounted on the insertion member 5.

  As shown in FIGS. 13 to 15, the U-shaped connecting member 44 may have a hook portion 45 at the end. In such a case, the connecting member 44 has a hook portion 45 protruding from the seal portion 13 of the first mounting member 41 as shown in FIG. 13, and a second mounting member as shown in FIG. It is embedded so that the other end side is exposed from the recess provided in 42. Then, when closing the first mounting member 41 and the second mounting member 42, as shown in FIG. 15, the hook portion 45 of the connection member 44 is hooked to the other end side, so that the first mounting member 41 and the second mounting member 42 are closed. It is possible to prevent the mounting member 41 and the second mounting member 42 from opening.

  The present invention can be used in, for example, waterproof or dustproof electronic devices.
