Japanese Patent No. 3991546

  Since the electronic device disclosed in Patent Document 1 seals the gap between the metal annular protrusion of the connector cover and the opening with a waterproof ring, sufficient dustproofness and waterproofness are ensured.

  However, in the electronic device, since the waterproof ring is exposed on the outer periphery of the connector cover, when the connector cover is removed from the electronic device, the waterproof ring may be damaged or dust may adhere to the waterproof ring. . For this reason, there is a risk that the dustproof and waterproof properties of the electronic device may be impaired.

  The present invention has been made in view of such circumstances, and is a portable device including a lid device that freely opens and closes an opening that opens in a housing, and the opening can be reliably sealed, In addition, an object is to provide a portable device with a small risk of contamination or damage of the sealing material.

  In order to solve the above-described problem, a mobile device according to the present invention includes a lid device that freely opens and closes an opening provided in a housing, and the lid device includes a lid body that closes the opening; A semi-solid sealing material, a sealing material filling tank filled with the semi-solid sealing material, and a seal that surrounds the opening and is in communication with the sealing material filling tank on a surface of the housing that contacts the lid It is characterized by comprising: a material inlet / outlet; and an insertion port through which a part of the lid is inserted when the lid closes the opening while communicating with the sealing material filling tank.

  The lid body is slidably supported by the housing, and when the lid body closes the opening, a sliding direction tip of the lid body is inserted into the insertion port. Good.

  Alternatively, a connector may be provided inside the opening.

  According to the present invention, when the lid is closed, the semi-solid sealing material bulged from the sealing material inlet / outlet closes the gap between the casing and the lid at the periphery of the opening, so that the opening can be reliably sealed. On the other hand, when the lid is opened, the semi-solid sealing material is pulled back into the sealing material filling tank and does not leak out of the housing, so that the risk of the semi-solid sealing material being damaged or soiled is reduced.

It is the external view which looked at the cover apparatus from the outer side of the housing | casing. It is sectional drawing of a cover apparatus. It is sectional drawing which shows the modification of a cover apparatus. It is sectional drawing which shows another modification of a lid | cover apparatus.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

  A cellular phone terminal 1 shown in FIG. 1 is an example of a portable device according to the present invention, and includes a first casing 2 and a second casing 3, both of which rotate via a hinge shaft 4. It is connected freely. A connector cover device 5 is provided on the side surface of the first housing 2.

  FIG. 2 is an external view of the connector cover device 5 as viewed from the outside of the first housing 2. As shown in FIG. 2, the connector cover device 5 includes a connector cover 6. The connector cover 6 is supported by a rail groove 7 formed in the first housing 2, and freely slides between an open position (see FIG. 2 (a)) and a closed position (FIG. 2 (b)). To do. The connector cover device 5 includes an opening 8. The opening 8 communicates the inside and the outside of the first housing 2. Further, a connector (not shown) is provided in the back of the opening 8 (inside the first housing 2), and the connector is connected to a signal cable inserted through the opening 8 from the outside.

  Further, as shown in FIG. 2C, rails 10 are formed on the upper and lower ends of the connector cover 6, and the rails 10 are engaged with the rail grooves 7. A seal material push-out claw 11 is formed at the front end of the connector cover 6 (the end close to the closed position). The operation of the sealing material pushing claw 11 will be described later.

  FIG. 3 is a cross-sectional view of the connector cover device 5 taken along line AA ′ in FIG. 2A. The connector cover 6 is in the open position (FIG. 3A), and the open position and the closed position are shown. A state in between (FIG. 3B) and a state in the closed position (FIG. 3C) are shown. In FIG. 3, the upper side of the connector cover device 5 corresponds to the space inside the first housing 2, and the lower side corresponds to the outside of the first housing 2.

  As shown in FIG. 3, a sealing material filling tank 12 is formed in the first housing 2 (more precisely, the inside of the shell constituting the outer shell of the first housing 2). The sealing material filling tank 12 communicates with the sealing material inlet / outlet 9. Further, an insertion port 14 is provided at a portion of the first housing 2 facing the sealing material pushing claw 11 of the first housing 2, and the insertion port 14 communicates with the sealing material filling tank 12.

  When the connector cover 6 is slid in the closed position direction, the sealing material pushing claw 11 at the tip of the connector cover 6 passes through the insertion port 14 and enters the inside of the sealing material filling tank 12 (see FIG. 3B). When the sealing material pushing claw 11 enters the inside of the sealing material filling tank 12, a part of the semi-solid sealing material 14 filled in the sealing material filling tank 12 is pushed out from the sealing material inlet / outlet 9. When the connector cover 6 reaches the closed position (see FIG. 3C), the semi-solid sealing material 14 pushed out from the sealing material filling tank 12 is moved between the housing 2 and the connector cover 6 at the periphery of the opening 8. Close the gap between them.

  Thus, the semi-solid sealing material 14 pushed out from the sealing material filling tank 12 through the sealing material inlet / outlet 9 closes the gap between the housing 2 and the connector cover 6 at the periphery of the opening 8. Is closed in a dust-tight and water-tight manner.

  Conversely, when the connector cover 6 is returned from the closed position (FIG. 3C) to the open position (FIG. 3A), the pressure applied to the semi-solid sealing material 14 by the sealing material pushing claw 11 disappears. The semi-solid sealing material 14 that has been pushed out of the sealing material filling tank 12 through the sealing material inlet / outlet 9 returns to the inside of the sealing material filling tank 12. Therefore, when the opening 8 is opened, the semi-solid sealing material 14 is not exposed to the outside of the first housing 2.

  The semi-solid sealing material 14 uses a material commonly called slime, in which an aqueous solution of polyvinyl alcohol and an aqueous solution of borax are mixed to crosslink polyvinyl alcohol molecules. The semi-solid sealing material 14 is formed by injecting and filling a mixture of an aqueous solution of polyvinyl alcohol and an aqueous solution of borax into the sealing material filling tank 12 before becoming semi-solid (before losing fluidity). Or you may make it inject | pour and fill the said mixture into the shaping | molding die which is not shown in figure, and what was shape | molded by the predetermined shape is integrated in the sealing material filling tank 12. FIG.

  As described above, when the connector cover 6 is in the closed position, the semi-solid sealing material 14 filled in the sealing material filling tank 12 is attached to the first casing 2 and the connector cover 6 at the periphery of the opening 8. Since the gap between them is closed, the opening 8 is closed in a dust-tight and water-tight manner. For this reason, the electronic components and the like installed inside the first housing 2 are sufficiently protected from dust and moisture. When the connector cover 6 is in the open position, the semi-solid sealing material 14 is drawn into the sealing material filling tank 12, so that the semi-solid sealing material 14 is not soiled or damaged. For this reason, the semi-solid sealing material 14 can be prevented from being damaged or damaged. Moreover, the fall of the sealing performance resulting from pollution and a breakage | damage can be suppressed.

  Further, since the cellular phone terminal 1 is provided with a connector inside the opening 8, a cable or the like can be drawn into the cellular phone terminal 1 and connected by simply opening the connector cover device 5. When a cable or the like is not connected, the connector is sufficiently protected from dust and moisture simply by closing the connector cover device 5.

  Further, since the connector cover 6 is slidably supported by the first housing 2 and is held by the first housing 2 while the opening 8 is opened, the connector cover 6 is lost or damaged. The danger of is small.

  Moreover, the above-mentioned embodiment is an illustration of embodiment of this invention, Comprising: The technical scope of this invention is not limited by the said description. The present invention can be implemented by application, modification or improvement within the scope of the technical idea described in the claims.

  For example, in the above-described embodiment, an example in which a material commonly called slime in which borax is added to polyvinyl alcohol and polyvinyl alcohol molecules are cross-linked is used as the semi-solid sealing material 14. The material of the material 14 is not limited to slime. Any material that is semi-solid, that is, a material that has an intermediate property between solid and liquid, and that maintains a predetermined shape in a state where internal and external forces are balanced, can be applied to other parts by pressing a part. Can be selected.

  In the above-described embodiment, an example in which the connector cover 6 slides between the open position and the closed position has been described, but other forms may be selected. For example, as shown in FIG. 4, the connector cover 6 is rotatably attached to the first housing 2 via the hinge 15, and the connector cover 6 is opened (see FIG. 4A) and closed ( You may make it rotate between FIG.4 (b)). Alternatively, as shown in FIG. 5, when the connector cover 6 is detachably attached to the first housing 2 and the connector cover 6 is attached to the first housing 2, the sealing material pushing claw 11 becomes a semi-solid sealing material. 14 may be pushed out from the sealing material entrance 9 (see FIG. 5B).

  In the above-described embodiment, the mobile phone terminal 1 is shown as an example of the mobile device, but the mobile device of the present invention is not limited to the mobile phone terminal 1. For example, the present invention is applied to various portable devices such as an electronic desk calculator, an electronic dictionary, a personal digital assistant (PDA), a notebook personal computer, a portable audio device, an electronic camera, a portable television receiver, and a portable communication device.
