Description

[Technical Field]

[0001] The present invention relates to an electronic device housing, and more particularly to a cover structure provided on an opening for, for example, an internal connector of an electronic device. [Background technology]

[0002] A dustproof cover structure is known in which a dustproof cap is integrated near the opening of an electronic device housing to prevent dust and other foreign matter from entering the opening (see Patent Document 1). Patent Document 1 describes an external connector retaining structure for an electronic device that prevents an external connector connected to an internal connector provided inside the housing of the electronic device from coming out and prevents the external connector from shaking even if an external force is applied to the connected external connector. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-220506 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional external connector retaining structure for an electronic device housing described in Patent Document 1, the housing does not have a structure for accommodating the lid when the lid is opened from the opening. Therefore, when the retaining part and the external connector engage, the lid is fixed in a specific position, but when applied to an electronic device housing that does not require a retaining structure when opened, the lid is not fixed to the housing when opened, so the lid moves freely around the hinge axis, causing the problem that the lid gets in the way when the electronic device is in use.

[0005] The present invention has been made in consideration of the above-mentioned problems of the prior art, and one example of an object of the present invention is to provide an electronic device housing in which the lid does not move when the lid is opened through an opening. [Means for solving the problem]

[0006] The electronic device housing of the present invention is an electronic device housing having a lid that can swing between a closed position that blocks an opening provided in a wall portion and an open position that opens the opening, wherein the lid is an elastomer member having a fixed end that is held in a fixed position in the area surrounding the opening in the wall portion and a plate-shaped portion that includes a swinging end that is the end opposite the fixed end and blocks the opening, the plate-shaped portion having a convex portion that extends in an in-plane direction, and the wall portion having a closing recess that engages with the convex portion to lock the lid in the closed position, and an opening recess that engages with the convex portion to lock the lid in the open position. [Effects of the Invention]

[0007] According to the present invention, there is provided an opening provided in the wall of an electronic device housing, a lid body formed integrally near the opening and made of an elastomer having rubber elasticity that can cover the opening, and a convex portion on the lid body that engages the lid body when the lid body is in the open position exposing the opening, and a concave portion on the wall.Therefore, when the opening is to be covered, the lid body can be tilted toward the opening so that it functions as a dust cap, and when the opening is not to be covered, the lid body can be tilted to the side opposite the opening so that it is tightly attached to the housing and stored in the wall.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an electronic device housing according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiment. Note that in the embodiment, components having substantially the same functions and configurations are designated by the same reference numerals, and redundant description will be omitted.

[0010] (First Example) Fig. 1 is a plan view showing a wall 1 and a lid 5 attached to the wall 1, which are part of the housing of an electronic device according to a first embodiment of the present invention. Fig. 2 is a schematic perspective view showing the upright lid 5 integrally formed with the wall 1 in this embodiment.

[0011] As shown in FIG. 1, the cover 5 is provided with an internal connector NC (for example, RJ11) that is provided on the inside thereof and exposed so that an external connector (not shown) can be inserted from the outside through a connector opening NCK.

[0012] 1 and 2, the electronic device has a cover 5 that can swing between a closed position (see FIG. 5) that closes a connector opening NCK provided in a wall 1 thereof and an open position (see FIG. 6) that opens the connector opening NCK. The wall 1 of the electronic device is provided with a connecting opening 2 that is a mortise, a closing recess 3 (through hole), an opening recess 4 (through hole), and the cover 5.

[0013] FIG. 3 is a front view showing the cover 5. The cover 5 is an integrally molded elastomer member made of rubber or the like. The cover 5 has a plate-shaped portion IJB between a fixed end KTB held in the connecting opening 2 (see FIG. 2) of the wall portion 1 and a swinging end YTB on the opposite side of the fixed end KTB. The plate-shaped portion IJB closes the connector opening NCK (see FIG. 2). The connecting opening 2 is provided at a fixed position in the peripheral area of the connector opening NCK of the wall portion 1 (see FIG. 2).

[0014] For example, the lid 5 is provided by insert molding or two-color molding on the wall 1 at a fixed position on the wall 1. Insert molding is a molding method in which an insert (wall 1 such as metal) is attached to a mold and resin is injected to create an integrated molded product. Two-color molding is a molding method in which different resin materials are combined to create an integrated molded product.

[0015] Fig. 4 is a schematic partial cross-sectional view showing the lid 5 in a part of the wall 1 near the connecting opening 2 taken along line AA in Fig. 2. Fig. 4 shows a cross section of the integrally molded wall 1 and lid 5. As shown in Fig. 4, the fixed end KTB of the lid 5 is integrally molded with the connecting opening 2 of the wall 1.

[0016] 1 to 3, the plate-shaped portion IJB of the cover 5 has a protrusion 6 extending in an in-plane direction near the swing end YTB. The plate-shaped portion IJB has a pair of protrusions 6 protruding in opposite directions from the plate-shaped portion IJB.

[0017] The tip of the protrusion 6 of each plate-like portion IJB is provided with an arrowhead portion AHD.

[0018] The wall 1 is provided with a closing recess 3 that engages with the protrusion 6 of the lid 5 at the closed position (see FIG. 5) to lock the lid 5, and an opening recess 4 that engages with the protrusion 6 at the open position (see FIG. 6) to lock the lid 5, corresponding to the position of the protrusion 6 of the lid 5. The closed and open positions of the lid 5 are positions in which the lid 5 is inverted around the fixed end KTB and the plate-shaped portion IJB is inside out.

[0019] A pair of closing recesses 3 on the wall 1 are provided facing each other on both sides of the connector opening NCK away from the fixed position (fixed end KTB). A pair of opening recesses 4 are provided at positions where the protrusions 6 of the plate-shaped portion IJB come into contact with the wall 1 when the lid 5 is turned over around the fixed position. The pair of protrusions 6 protruding in opposite directions from the plate-shaped portion IJB correspond to the pair of closing recesses 3 and opening recesses 4 at their respective positions.

[0020] In this embodiment, the protrusion 6 of the lid 5 is inserted into the closing recess 3 or the opening recess 4 of the wall 1, and the lid 5 is held in a locked state.

[0021] FIG. 7 is a schematic partial cross-sectional view showing the cover 5 in a part near the connecting opening of the wall 1 taken along line AA in FIG. 5, showing the cover 5 in the closed position.

[0022] The closing recess 3 and the opening recess 4 of the wall 1 have a step 7 that engages with the arrowhead joint HDS of the arrowhead portion AHD of the protrusion 6 of the lid 5. When the protrusion 6 of the lid 5 is inserted into the closing recess 3 or the opening recess 4, it comes into contact with and engages with the opening recess 4 or the closing recess 3 (step 7) due to the rubber elastic force caused by the deformation of the protrusion 6, and the lid 5 is locked to the wall 1.

[0023] A modified example in which the lid 5 is engaged with the wall 1 is shown in Fig. 8. Fig. 8 is a schematic partial cross-sectional view showing the lid 5 in a part of the housing wall near the closing recess of the electronic device in a modified example of the first embodiment. In this modified example, a part of the wall 1 around the fixed end KTB is recessed (depressed portion) so that the plate-like portion IJB of the lid 5 extends closely along the surface of the wall 1 in the closed position and the open position.

[0024] (Second Example) Fig. 9 is a schematic exploded perspective view showing the wall 1 and lid 5 of an electronic device of a second embodiment. This embodiment is the same as the first embodiment except that the wall 1 and lid 5 are integrated by fitting together rather than being integrally molded. Fig. 10 is a schematic partial cross-sectional view of the connection showing the state in which the wall 1 and lid 5 are snap-fit connected.

[0025] The lid 5 of this embodiment has a connecting opening 2 that is provided at a fixed position on the wall 1 and into which the fixed end KTB of the lid 5 is later fitted. The wall 1 and the lid 5 have a snap-fit structure in which the rectangular fixed end KTB of the lid 5 is inserted into the rectangular connecting opening 2 of the wall 1, and the lid 5 is held in a fixed state.

[0026] A protrusion 2b protruding in the in-plane direction of the wall 1 is provided on the inner surface of the connecting opening 2 of the wall 1, and a fixed end KTB of the lid 5 is provided with a recess KTBa that fits into the protrusion 2b.

[0027] In this way, in this embodiment, a pair of recesses KTBa are provided on the main surface of the lid body 5, and a pair of protrusions 2b are provided in the connecting opening 2 of the wall portion 1, each of which has a complementary shape and is staggered, and by fitting the two pairs of recesses and protrusions together, it is possible to mold the lid body 5 as a separate part rather than as a single unit, and then assemble and fix it to the wall portion 1.

[0028] (Explanation of the operation of the first and second embodiments) When the internal connector NC is not in use, the connector opening NCK is covered with the lid 5. The protrusion 6 at the tip of the lid 5 is inserted into the blocking recess 3 of the wall 1. The head joint HDS of the head part AHD of the protrusion 6 at the tip of the lid 5 engages with the step 7 on the inside of the wall 1 of the blocking recess 3, thereby keeping the connector opening NCK closed.

[0029] When using the internal connector NC, the protrusion 6 at the tip of the lid 5 is inserted into the opening recess 4 provided on the opposite side of the closing recess 3 in the wall 1. The head joint HDS of the head part AHD of the protrusion 6 at the tip of the lid 5 engages with the step 7 on the inside of the wall 1 of the opening recess 4, thereby keeping the connector opening NCK open.

[0030] (Explanation of effect) According to the first and second embodiments, when the internal connector NC is not in use, the connector opening NCK is covered with the lid 5 and the protrusion 6 at the tip of the lid 5 is inserted into the blocking recess 3 to close the lid, as shown in Fig. 5, thereby achieving a dustproof effect. When the internal connector NC is used, the protrusion 6 at the tip of the lid 5 is inserted into the opening recess 4 provided on the opposite side of the blocking recess 3, as shown in Fig. 6, so that the lid can be fixed tightly to the wall 1. Therefore, the lid 5 does not get in the way when the internal connector NC is in use.

[0031] (Third Example) Fig. 11 is a schematic perspective view showing the state of the lid 5 erected on the wall 1 of an electronic device of the third embodiment. Fig. 12 is a front view showing the lid 5 of this embodiment. This embodiment is the same as the first embodiment except that the wall 1 and the lid 5 are integrated by fitting together rather than being integrally molded, and further the shape of the convex portion 6 of the plate-like portion IJB of the lid 5 is changed from an arrowhead shape to a tongue shape, and the shape of the fixed end KTB of the lid 5 is changed to a columnar shape.

[0032] As shown in Figure 11, the connecting opening 2a of the wall portion 1 is provided at a fixed position in the surrounding area of the connector opening NCK of the wall portion 1, and is provided as a circular or rectangular through hole on the center line of the connector opening NCK with a length shorter than the length of the connecting opening 2 of the first embodiment.

[0033] As shown in Fig. 11, each of the closing recess 3a and the opening recess 4a of the wall 1 is a slit into which the protrusion 6 of the cover 5 is inserted while coming into contact with it. The closing recess 3a has a pair of slits that are parallel and facing each other on both sides of the connector opening NCK away from the fixed position. The opening recess 4a has a pair of slits that are parallel and located at positions where the protrusion 6 of the plate-shaped portion IJB comes into contact with the wall 1 when the cover 5 is rotated 90 degrees along the wall 1 around the connecting opening 2a in the fixed position.

[0034] As shown in Figures 11 and 12, the fixed end KTB of the cover body 5 has a columnar end RD with a head RHD that can be deformed and fitted loosely into the connecting opening 2a of the wall portion 1 and cannot come out of the connecting opening 2a.

[0035] The lid 5 of this embodiment has a connecting opening 2a into which the columnar end RD equipped with the head RHD of the fixed end KTB of the lid 5 is later fitted. The wall 1 and the lid 5 are structured so that the columnar end RD equipped with the head RHD of the lid 5 is inserted into the connecting opening 2a of the wall 1, and the lid 5 is held in a fixed state so that it can swing.

[0036] Fig. 13 is a plan view showing the closed position of the cover in a part near the opening of the electronic device of the third embodiment. Fig. 14 is a plan view showing the closed position of the cover 5 in a part near the opening of the electronic device of the third embodiment.

[0037] (Explanation of the operation of the third embodiment) When the internal connector NC is not in use, the connector opening NCK is covered with the cover 5. The protrusion 6 at the tip of the cover 5 is inserted into the slit in the closing recess 3a of the wall 1. By inserting the protrusion 6, friction with the slit keeps the connector opening NCK closed.

[0038] When using the internal connector NC, rotate the lid 5 by 90 degrees and insert the protrusion 6 at the tip of the lid 5 into the slit in the opening recess 4a located diagonally next to the closing recess 3a in the wall 1. By inserting the protrusion 6, friction with the slit keeps the connector opening NCK open.

[0039] (Explanation of effect) According to this embodiment, as shown in FIGS. 13 and 14, the open position of the lid 5 can be set to a position where the closed position of the lid 5 is rotationally symmetrical about the fixed position.

[0040] Although the slits of the convex portion 6 of the plate-shaped portion IJB and the closing recess 3a and the opening recess 4a of the wall portion 1 are not shown, at least one of each may be provided as long as friction can be obtained by appropriately changing their width and span.

[0041] In the third embodiment, the tongue-shaped protrusion 6 of the plate-shaped portion IJB of the lid 5 can be changed to the arrowhead shape of the first and second embodiments, and at the same time, the closing recess 3 and the opening recess 4 of the wall portion 1 can be changed from slits to have steps 7. Conversely, the tongue-shaped protrusion 6 of the plate-shaped portion IJB and the slits of the closing recess 3a and the opening recess 4a can be applied to the first and second embodiments.

[0042] In the above embodiment, the connector opening NCK is applied to dustproofing of RJ11, but by adjusting the size of the opening to be covered, the present invention can also be applied to various connector openings of electronic devices such as RJ45, USB, earphone jack, etc. Note that the swing end YTB of the plate-shaped portion IJB of the cover 5 may be formed with an operating piece (not shown) to make it easier to open the cover 5.
