Definitions
- the present invention relates to a housing for various electronic devices such as a mobile phone, a PDA (Personal Data Assistance), a PC (Personal Computer), and more particularly to a waterproof structure of the housing.
- housings of many electronic devices have a waterproof structure.
- an elastic seal member is disposed between the lower cover and the upper cover. More specifically, an elastic seal member is disposed between the side wall end surface of the lower cover and the side wall end surface of the upper cover. Such a sealing member is sandwiched between the opposing side wall end faces and compressed, thereby preventing liquid from entering the casing.
- the size is limited in relation to the width and flatness of the side wall end faces. That is, if the width of the seal member is wider than the width of the side wall end surface, the seal member will protrude outside the housing. On the other hand, if the width of the sealing member is too narrow relative to the width of the side wall end surface, the sealing member may be stretched or fall when the sealing member is sandwiched between the opposing side wall end surfaces. When the seal member extends or falls down, a predetermined compression state cannot be obtained and the waterproof function is lowered.
- the thickness of the seal member is 1.0 mm
- a compression rate of 30% to 50% can be obtained.
- the seal member in order to obtain the same compression rate, the seal member must be compressed until the thickness becomes 0.15 mm to 0.25 mm. Therefore, if there is an unevenness with a height of 0.15 mm or more on the side wall end face of the cover that sandwiches the seal member, the compression of the seal member becomes incomplete.
- the seal member is required to have a certain size or more, and as a result, the thickness of the side walls of the lower cover and the upper cover also increases.
- the side wall of the cover becomes thick, the volume of the housing decreases. That is, the mounting space of the housing is reduced. For this reason, the number of mounted components must be reduced at the expense of the function and performance of the electronic device. Alternatively, the mounting density must be increased excessively.
- An object of the present invention is to provide a housing for an electronic device that has a sufficient waterproof function and has a mounting space equal to or more than a housing that does not have a waterproof function.
- One of the housings for an electronic device includes a main body having a bottom and a side wall rising from the bottom, a lid member fitted inside the side wall of the main body, and between the lid member and the main body.
- a waterproof sealant that seals a gap between the lid member and the main body, and an operation part provided on the lid member, and a peripheral edge of the operation part and a surface of the lid member And are joined by waterproof tape.
- Another one of the electronic device housings according to the present invention includes a main body having a bottom and a side wall rising from the bottom, a lid member fitted inside the side wall of the main body, the lid member and the main body, A waterproof sealant that seals a gap between the lid member and the main body, and an operation portion provided on the lid member, and a peripheral edge of the operation portion and the lid member The surface is joined by the waterproof sealant.
- a housing for an electronic device having a sufficient waterproof function and having a mounting space equal to or greater than that of a housing not having a waterproof function is realized.
- FIG. 2 is a plan view of the lower housing shown in FIG. 1.
- FIG. 3 is an AA cross-sectional view of the lower housing shown in FIG.
- FIG. 5 is a cross-sectional view showing one of modifications of the mobile phone shown in FIG.
- FIG. 10 is a cross-sectional view showing another example of a modification of the mobile phone shown in FIG. 1.
- FIG. 10 is a cross-sectional view showing another example of a modification of the mobile phone shown in FIG. 1.
- FIG. 10 is a cross-sectional view showing another example of a modification of the mobile phone shown in FIG. 1.
- FIG. 1 is a perspective view of a mobile phone according to the present embodiment.
- the illustrated mobile phone 1 includes an upper casing 2 and a lower casing 3 that are rotatably connected.
- a liquid crystal panel 4 that constitutes a display unit is provided on the front surface of the upper casing 2.
- the upper housing 2 and the lower housing 3 can be shifted from the closed state in which the front surfaces face each other to the open state shown in FIG. 1 or from the open state to the closed state by a turning operation.
- FIG. 2 is an enlarged plan view of the front surface of the lower casing 3.
- FIG. 3 is a cross-sectional view of the lower housing 3 shown in FIG.
- the lower casing 3 is composed of a main body 10 and a lid member 20.
- the main body 10 and the lid member 20 have a bottom portion and side walls that rise substantially vertically from each side of the bottom portion.
- the main body 10 and the lid member 20 have a substantially box shape having an opening on one surface.
- the main body 10 is made of an engineering plastic such as polycarbonate.
- the lid member 20 is made of a pressed stainless steel sheet.
- the lid member 20 is fitted inside the main body 10 to close the opening of the main body 10.
- the lid member 20 is fitted inside the main body 10 such that the opening thereof covers the bottom inner surface 11 of the main body 10.
- the side wall outer surface 21 of the lid member 20 is in contact with the side wall inner surface 12 of the main body 10 with almost no gap.
- necessary components such as a battery and a circuit board are mounted in the main body 10. That is, necessary components mounted in the main body 10 are covered with the lid member 20.
- the metal lid member 20 arranged almost without any gap inside the plastic body 10 plays a role of improving the strength of the entire lower casing.
- the switch circuit 30 and the key sheet 5 are arranged in this order on the bottom outer surface 22 of the lid member 20.
- the switch circuit 30 is an FPC (Flexible Printed Circuits) having a contact member 31, an electrical contact 32 and a pressing sheet 33.
- the contact member 31 faces the electrical contact 32 and is fixed by a pressing sheet 33.
- the key sheet 5 has a sheet-like base material 50 having flexibility, and an operation button 51 arranged on the base material 50.
- the base material 50 bends.
- the contact member 31 of the switch circuit 30 in the lower layer of the key sheet 5 is deformed to come into contact with the electrical contact 32, and the contact member 31 and the electrical contact 32 are conducted.
- the lid member 20 plays a role of receiving pressure when the operation button 51 is pressed, in addition to a role of improving the strength of the entire lower casing.
- a waterproof sealant 60 is filled between the lid member 20 and the main body 10 along the outer periphery of the bottom of the lid member 20. Specifically, a waterproof sealant 60 is filled between the corner of the lid member 20 and the side wall inner surface 12 of the main body 10. Thereby, the penetration
- the corner portion of the lid member 20 is a boundary portion between the bottom portion and the side wall of the lid member 20.
- the waterproof sealant 60 may be filled using an air-pass type dispenser.
- a resin having waterproof properties such as a silicone-based general-purpose sealant material, an elastic adhesive, and an acrylic sealant can be used.
- the waterproof sealant 60 is bonded to the lid member 20 and the main body 10 by its own adhesive force. Therefore, the waterproof sealant 60 is deformed following the deformation of the lid member 20 and the main body 10 to maintain waterproofness.
- the seal member used in the conventional product is sandwiched between the upper and lower covers, but is not bonded to the cover. Therefore, when the upper and lower covers are deformed, the compression amount of the seal member may partially change, and the waterproofness may be reduced.
- the peripheral edge of the key sheet 5 is joined to the bottom outer surface 22 of the lid member 20 by a waterproof tape 70. This prevents liquid from entering between the key sheet 5 and the switch circuit 30. It is also possible to fix the peripheral edge of the key sheet 5 to the side wall end face of the main body 10. However, in order to fix the peripheral edge of the key sheet 5 to the side wall end surface of the main body 10, it is necessary to make the width of the side wall end surface a certain width or more. Therefore, by fixing the peripheral edge of the key sheet 5 to the bottom outer surface 22 of the lid member 20, the width of the side wall end surface of the main body 10 can be reduced. In other words, the side wall of the main body 10 can be made thinner and the volume of the lower housing 3 can be expanded.
- an opening may be formed on the main body 10 or the lid member 20 in order to attach a battery cover (not shown) or an I / O cover.
- the openings can be waterproofed by the same structure and method as before.
- the liquid reservoir 61 may be formed by retracting the corner of the lid member 20 toward the inside of the lid member 20.
- the filling amount of the waterproof sealant 60 is increased.
- the waterproof sealant 60 can be stably filled even when a machine is used. Specifically, the waterproof sealant 60 is prevented from protruding or flowing out.
- the filling of the waterproof sealant 60 can be performed manually, but by automating using a machine, effects such as shortening the manufacturing time, stabilizing the quality, and reducing the manufacturing cost can be obtained.
- the lid member 20 and the key sheet 5 may be joined by a waterproof sealant 60.
- the waterproof tape 70 shown in FIG. 3 becomes unnecessary, and the cost is reduced.
- the waterproof sealant 60 flows down into the main body 10 by using the waterproof sealant 60 having thixotropy. Can be prevented.
