The waterproof member has, between the seal member and an outside surface of the projecting member, a notch portion 33 where the seal member and the projecting member are at least partially in non-contact with each other along an outer peripheral direction of the projecting member.

Description

  The present invention relates to a waterproof member and an electronic device including the same.

  In recent years, in electronic devices such as digital cameras, mobile phones, tablet PCs, etc., a waterproof member that closes an opening formed in a housing corresponding to a terminal or a connector in order to meet the high waterproof demand from consumers. Is adopted. As an example of the structure of the waterproof member, a plate-shaped reinforcing member that protrudes inward of the opening is provided on the back surface of the lid that can open and close the opening formed in the housing, and the outer peripheral surface of the reinforcing member A structure is known in which a rubber packing is attached to the inner surface and the inner surface of the opening and the packing are pressed against each other when the lid is closed (see, for example, Patent Document 1 and Patent Document 2). .

  By using such a waterproof structure, the packing comes into contact with the side surface of the opening, so that the waterproof function can be exhibited with a constant compressive force regardless of the magnitude of the force in the pushing direction of the lid. In addition, since the mechanism for locking the lid to the housing is simple, it is possible to reduce the thickness of the waterproof mechanism including the lid and reduce the manufacturing cost. On the other hand, high dimensional accuracy is required for the reinforcing member and packing provided on the back side of the lid. In addition, if the packing is simply attached to the outer peripheral surface of the reinforcing member, the packing is likely to be displaced from the side surface of the reinforcing member due to friction between the inner surface of the opening and the packing. In this sense, a structure in which a packing is attached to the side surface of the reinforcing member and a waterproof function is exhibited by pressure contact between the inner side surface of the opening and the packing inherently has a risk of significantly reducing the waterproof performance. In order to reduce such a risk, in the waterproof structure disclosed in Patent Document 2, the reinforcing member and the packing are firmly fixed by integral molding so that the packing is not easily dropped or displaced from the reinforcing member.

  However, the conventional waterproof structure as described above still has a problem that cannot be solved. When the opening is closed by the lid, the packing surrounding the outer peripheral surface of the reinforcing member is compressed by the inner wall surface of the opening, and extends inward of the opening by the compressed volume. For this reason, a space corresponding to the extension of the packing is required inside the opening, and it is difficult to reduce the thickness of the opening in the inward direction. Also, if there is no such space, when the lid is closed, the packing loses its place and becomes compressed excessively. Excessive compression of the packing may cause a large stress on the lid and the locking portion between the lid and the casing, and as a result, the lid may open or the lid and the locking portion may be damaged.

  The present invention has been made to solve such a problem, and an object of the present invention is to reduce the inward thickness of the opening of the housing and to reduce an excessive load on the waterproof structure.

  One embodiment of the present invention for achieving the above object is a waterproof member that closes an opening formed in a housing of an electronic device, and the waterproof member includes a cover member that covers the opening, and a back surface of the cover member. A cover member and a projecting member formed to project in the direction of the opening with a smaller contour than the opening, and a seal member fixed to the projecting member and having a contour larger than the contour of the opening, It is a waterproof member provided with the notch part which becomes at least partially mutually non-contact along the outer peripheral direction of a protrusion member between the outer surface of a protrusion member.

  Another embodiment of the present invention is a waterproof member in which a cutout portion is formed over the entire circumference of the outer surface of the protruding member.

  Another embodiment of the present invention is a waterproof member that at least partially covers the surface of the protruding member that faces the cover member by the seal member.

  Another embodiment of the present invention is a waterproof member in which the thickness of the sealing member is the same as or lower than the back surface of the protruding member.

  Another embodiment of the present invention is a waterproof member in which a seal member and a protruding member are integrally formed.

  One embodiment of the present invention is an electronic device including any of the waterproof members described above.

Examples of the resin include acrylic, polypropylene (PP), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), polycarbonate (PC), or a polymer alloy composed of two or more resins. Examples of the rubber include thermoplastic elastomers, thermosetting elastomers, and natural rubber. Although the projecting member 20 does not limit the constituent material at all, it is suitably comprised from resin, a metal, ceramics, etc. As resin, the material similar to the cover member 10 can be illustrated. The seal member 30 is preferably formed from an elastic material that is more flexible than the protruding member 20. Examples of the elastic material include thermoplastic elastomers, thermosetting elastomers, and natural rubber. Among them, silicone rubber or urethane rubber can be exemplified as a more preferable material.

  FIG. 4 is a plan view with the back surface of the waterproof member shown in FIG. 2 facing up. FIG. 5 shows a cross-sectional view taken along line AA of FIG.

  The protruding member 20 is a rectangular thin plate having an elliptical shape in a plan view, more precisely, a tip bay arc shape. The protruding member 20 includes eight concave portions 25 that are recessed inward from the outer surface on the outer surface thereof. Between the seal member 30 and the outer surface of the projecting member 20, notch portions 33 that are not in contact with each other are provided in the recessed portions 25 that are partially scattered along the outer circumferential direction of the projecting member 20. The cutout portion 33 has a groove shape cut from the back surface side to the front side of the protruding member 20. In this embodiment, the cutout portion 33 has a recessed shape on both sides of the protruding member 20 and the seal member 30 in plan view. Prepare. The seal member 30 includes a bottom plate 31 that forms the bottom surface of the notch portion 33 and a rib 32 that faces the recess 25 with the notch portion 33 interposed therebetween. The seal member 30 is in contact with the entire outer surface of the protruding member 20 at a portion other than the concave portion 25 of the protruding member 20. However, in the recess 25, the seal member 30 contacts the outer surface of the protruding member 20 only on the inner surface 31 a of the bottom plate 31. That is, the seal member 30 is not in contact with the entire surface of the recess 25 in the thickness direction at the recess 25. In addition, the recessed part 25 is not limited to eight pieces, You may equip the outer surface of the protrusion member 20 with 1-7 pieces or 9 pieces or more. In addition, the shape of the recess 25 may be any shape, and is not limited to the semi-cylinder as exemplified in this embodiment, and may be a semi-elliptical column or a semi-polygonal column. In order for the seal member 30 to be easily deformed so as to narrow the recess 25 against compression from the inner wall of the opening 3, the shape of the recess 25 in a plan view is preferably semicircular, semi-elliptical, or The streamline is elongated along the periphery of the protruding member 20.

  As shown in FIG. 5, the seal member 30 covers the front side surface of the protruding member 20, that is, the front side surface facing the bottom surface 12 of the cover member 10 (the right side from the line P in FIG. 5). The unit 34 is provided. That is, in this embodiment, the seal member 30 covers the outer surface from the front surface of the protruding member 20. In addition, the front side coating | coated part 34 may cover the front side surface of the protrusion member 20 completely, or may cover it partially. Further, the thickness of the seal member 30 may be lower or higher than the position of the back surface of the protruding member 20, or may be the same height as in this embodiment. From the viewpoint of promoting the space saving, it is preferable that the height is the same as or lower than the back surface of the protruding member 20. The seal member 30 can be fixed to the protruding member 20 by a technique such as adhesion, and more preferably integrally formed with the protruding member 20 by a technique such as two-color molding or insert molding. In the case where the integral molding is performed, the seal member 30 including a reactive group that is chemically bonded to the projecting member 20 is used under the condition that the projecting member 20 is made of synthetic resin and the seal member 30 is made of rubber. It is more desirable to bond the protruding member 20 and the seal member 30 firmly by applying a primer treatment or the like to a region of the protruding member 20 that contacts the seal member 30.

  FIG. 6 is a plan view of the state of the waterproof member when a force is applied to the seal member from the inner wall of the opening when the waterproof member shown in FIG. Show. FIG. 7 is a cross-sectional view taken along the line C-C (7A) of the region B in FIG. 6 and an enlarged view (7B) of the region B, schematically showing changes in the seal member that receives force from the inner wall of the opening. .

  When the opening 3 is closed by the waterproof member 2, the seal member 30 receives the compressive force F from the inner wall of the opening 3 over the entire periphery. Thus, the inner wall of the opening 3 and the seal member 30 are in close contact with each other, and a waterproof function can be exhibited. As shown in FIG. 6, when the seal member 30 receives the compressive force F from the inner wall of the opening 3 over the entire circumference, the seal member 30 is deformed in the direction of the arrow L so as to fill the notch 33. . In particular, the rib 32 located opposite to the recess 25 across the notch 33 is greatly deformed. As a result, the seal member 30 receives the compressive force F from the inner wall of the opening 3 and deforms so as to be crushed and is not pushed into the opening 3 in the direction of narrowing the notch 33. Deform. Therefore, it is not necessary to provide a space for the seal member 30 to enter in the opening 3, and the waterproof structure can be made thinner. In addition, the notch portion 33 prevents excessive compression deformation of the seal member 30 and contributes to reducing an excessive load on the waterproof structure.

  FIG. 8 is a cross-sectional view (8A, 8B) of a modification of the seal member of FIG.

  The seal member 30 may be fixed only on the outer surface without covering the front surface of the protruding member 20. In that case, in the recess 25, the seal member 30 is fixed so as to contact the inner side surface 31a of the bottom plate 31 as shown in (8A). Further, as shown in (8B), the seal member 30 may be fixed to the protruding member 20 on the outer side surface and the front side surface other than the concave portion 25 without contacting the concave portion 25. In the modification shown in FIG. 8, the seal member 30 is longer in the direction of the opening 3 than the back surface of the protruding member 20. Even in such a form, the seal member 30 is deformed in the direction of narrowing the cutout portion 33 without extending in the direction of the opening 3 due to the presence of the cutout portion 33.

(2) Method for Producing Waterproof Member FIG. 9 is a step of the method for producing the waterproof member shown in FIG. 2 and shows a situation in which pellets are arranged on the outer surface of the protruding member constituting the waterproof member. FIG. 10 shows a state in which the seal member is integrally formed with the protruding member after the step shown in FIG.

  A cylindrical pellet 45 having a height t2 (<t1) is arranged in the eight concave portions 25 of the protruding member 20 having a thickness t1. It is preferable that the pellet 45 and the concave portion 25 have a structure that can be fitted. This is because when the seal member 30 and the protruding member 20 are integrally formed, the protruding member 20 in which the pellet 45 is fitted is easily moved. A space 25 a (see FIG. 10) formed when the pellet 45 is disposed in the recess 25 is a fixing portion between the seal member 30 and the recess 25 of the protruding member 20. After disposing the pellet 45 in the recess 25, the projecting member 20 is set in a die 50 for integral molding (consisting of an upper die 51 and a lower die 52). The upper mold 51 includes a concave portion 51 a that is recessed inwardly on the surface facing the lower mold 52. Similarly, the lower mold 52 includes a recess 52 a that is recessed inward on the surface facing the upper mold 51. The recess 51 a and the recess 52 a form a space in which the seal member 30 is integrally formed with the protruding member 20 by aligning the upper mold 51 and the lower mold 52 with each other. The protruding member 20 with the pellet 45 placed in the recess 25 is set in the mold 50, and an uncured rubber material is poured in the direction of arrow R from the gate of the upper mold 51 toward the inside of the mold 50. Next, the entire mold 50 is heated. After a predetermined time has passed at a temperature suitable for vulcanization of the rubber material, the upper mold 51 and the lower mold 52 are opened, and the seal member 30 is integrally formed on the outer surface and the front surface of the protruding member 20. Take out the compact. Thereafter, the pellet 45 is removed from the recess 25, the gate mark of the poured rubber material is cut, and the process of integrally forming the seal member 30 on the protruding member 20 is completed. Finally, the integral molded body is fixed to the back surface of the cover member 10 to complete the waterproof member 2. In addition, the height t2 of the pellet 45 can be made equal to the thickness t1 of the protruding member 20. In that case, the seal member 30 is fixed to the outer surface other than the concave portion 25 and the back surface of the protruding member 20 without being fixed to the concave portion 25 of the protruding member 20. Furthermore, in the present embodiment, the notched portion 33 is formed by the pellet 45 when integrally molding, but by forming a protrusion (pin) having the same shape as the pellet in the lower mold 52 in advance, the cut portion 33 is formed. The notch part 33 can also be formed. Thereby, the process of removing the pellet 45 from the sealing member 30 can be omitted, and the sealing member 30 can be prevented from being damaged due to the process.

2. Second Embodiment Next, a waterproof member and an electronic device including the same according to a second embodiment of the present invention will be described. In the second embodiment, portions common to the first embodiment are denoted by the same reference numerals, and redundant description is omitted. The difference between the waterproof member according to the second embodiment and that according to the first embodiment is the form of the cutout portion 33, and the other points are the same as those of the first embodiment.

(1) Structure of waterproof member FIG. 11: shows the perspective view which removed the waterproof member from the electronic device which concerns on 2nd embodiment of this invention, and turned the back surface up. FIG. 12 is a plan view of the waterproof member shown in FIG. FIG. 13 is a cross-sectional view taken along the line D-D in FIG. 12, and schematically illustrates a change in the seal member that receives a force from the inner wall of the opening of the electronic device according to the second embodiment.

  The waterproof member 2a according to the second embodiment includes a protruding member 20 and a seal member 30 including a cutout portion 33 over the entire circumference of the outer surface thereof. When the opening 3 is closed with the waterproof member 2 a, the seal member 30 receives a compressive force from the inner wall of the opening 3. At that time, as indicated by an arrow L in FIG. 13, the seal member 30 is deformed such that the rib 32 positioned outside the notch portion 33 falls to the notch portion 33 side and the width thereof is narrowed. Therefore, it is not necessary to provide a space for the seal member 30 to enter in the opening 3, and the waterproof structure can be made thinner. In addition, the notch portion 33 prevents excessive compression deformation of the seal member 30 and contributes to reducing an excessive load on the waterproof structure.

  In this embodiment, the sealing member 30 is in contact with the protruding member 20 at the inner side surface 31 a of the bottom plate 31 and the front side covering portion 34. However, the cutout portion 33 may have the same depth as the thickness of the protruding member 20 so that the seal member 30 contacts only the front surface of the protruding member 20. Further, the seal member 30 may be in contact with the protruding member 20 only on the inner surface 31 a of the bottom plate 31.

(2) Method for Producing Waterproof Member FIG. 14 is a step of the method for producing the waterproof member shown in FIG. 11 and shows a situation in which an annular member is arranged on the outer surface of the protruding member constituting the waterproof member.

  On the outer periphery of the protruding member 20 having a thickness t1, an annular member 60 having an elliptical ring shape that is slightly larger than the protruding member 20 having a height t2 (<t1) is disposed. A portion of the outer surface of the projecting member 20 that is not covered by the annular member 60 is a fixing portion between the seal member 30 and the projecting member 20. After the annular member 60 is mounted on the protruding member 20, the seal member 30 and the protruding member 20 are integrally formed. The integral molding is performed through the same process as in the first embodiment. Finally, the annular member 60 is removed, and the integrally molded body is fixed to the back surface of the cover member 10 to complete the waterproof member 2a. Instead of the annular member 60, a tray-shaped member having a bottom surface in the annular member 60 may be used, and the member may be attached to the protruding member 20 and then the integral molding process may be executed. The height t2 of the annular member 60 can be made equal to the thickness t1 of the protruding member 20. In that case, the seal member 30 does not adhere to the outer surface of the protruding member 20, and adheres only to the back surface of the protruding member 20. Furthermore, in the present embodiment, the notched portion 33 is formed by the annular member 60 when integrally forming, but this can be handled by forming a protrusion (pin) having the same shape as the pellet in the lower mold 52 in advance. By doing so, the notch part 33 can also be formed. Thereby, the process of removing the annular member 60 from the seal member 30 can be omitted, and the seal member 30 can be prevented from being damaged due to the process.

3. Other Embodiments Although the embodiments of the waterproof member according to the present invention and the electronic device including the waterproof member have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made.

  In the first embodiment described above, the cutout portion 33 is configured by the concave portion 25 of the protruding member 20 and a portion that faces the concave portion 25 and is recessed in the width direction of the seal member 30. However, the cutout portion is not limited to this. For example, as shown in (15A), the cutout portion 73 may be configured only from a portion recessed in the width direction of the seal member 30. In this case, it is not necessary to provide the recess 25 existing in the first embodiment on the outer surface of the protruding member 20. Moreover, in 2nd Embodiment, the example which provides the notch part 33 of the shape depressed over the perimeter of the outer surface of the protrusion member 20 only in the width direction inner side of the sealing member 30 was demonstrated. On the other hand, as shown to (15B), you may form the notch part 83 hollow inward over the outer periphery of the protrusion member 20 over the perimeter. That is, in the waterproof members 2 and 2a according to the present invention, if a non-contact portion can be provided between the projecting member 20 and the seal member 30, at least one of the projecting member 20 and the seal member 30 has a width thereof. It can be recessed in the direction to form a notch. In the case of the configuration shown in (15B), the protrusion of the mold corresponding to the notch portion 83 is carried out when insert molding is performed in which the protruding member 20 is charged into the mold and the seal member 30 is integrally formed with the protruding member 20. The protruding member 20 can be positioned by the portion. Therefore, the projecting member 20 can be firmly fixed, and high-precision molding that does not even cause a thin burr is possible.

  The present invention can be used for an electronic device having a waterproof function.
