Abstract:
The switch case includes a metal plate having a first surface and a second surface that is at a side opposite to the first surface, and a resin case embedding a part of the metal plate. The resin case includes a housing portion having an opening formed on a surface of the resin case. The metal plate includes a terminal portion, a contact portion, and an intermediate portion positioned between the terminal portion and the contact portion. The terminal portion is exposed from the surface of the resin case, and the intermediate portion is embedded in the resin case. The intermediate portion is provided with at least one through-hole penetrating the first surface and the second surface. The contact portion includes a part of the first surface exposed to the housing portion of the resin case. In the at least one through-hole, the hole diameter of the at least one through-hole at the second surface is larger than the hole diameter of the at least one through-hole at the first surface.
Abstract:
An assembled structure includes a metal plate having a first main surface and a second main surface, and having a through hole, as well as a resin member assembled with the metal plate and disposed on the second main surface side so as to have a portion fitted within the through hole. Assuming that an opening when the through hole is viewed in a plan view has a first width at a point along the opening and a second width measured in parallel to the first width at a point shifted toward the outer side of the opening, a combination of the first width and the second width can be determined such that the second width is larger than the first width.
Abstract:
This application relates to systems, methods, and apparatus for welding switches to a bracket for placement inside of a computing device. Each switch can include a metal region that can be welded to a metal surface of a bracket. The metal region of the switch can be a cover that is formed around a body of the switch, or an inserted molded region that is provided on a surface of the switch. The bracket can include recesses that can be used to identify when a switch is abutting the bracket before welding the switch to the bracket. Multiple welds can be provided on each switch to ensure a rigid connection exists between the bracket and switch. Welding can be performed in batches by loading multiple brackets and switches onto a pallet, and thereafter loading the pallet into a welding machine.
Abstract:
A key structure in an electronic apparatus case includes a top portion that is exposed through a surface of the case, a shaft portion that extends from the top portion and includes a elastomer at a tip of the shaft portion, and a stopper portion that projects from a periphery of the top portion to engage and that is engaged so as to be in contact with the switch in the state where the elastomer is contracted.
Abstract:
A key structure comprises a bottom portion, a keycap and an elastic element. The bottom portion includes a pressing portion. The keycap includes a conducting portion and a fixing portion. The elastic element is a hollow structure formed by linear winding, and it is disposed between the bottom portion and the keycap. The conducting portion passes through the hollow structure and corresponds to the pressing portion, and the fixing portion is used to fix the elastic element. The keycap is movably fixed to the bottom portion, and the conducting portion is connected to the pressing portion when the keycap moves towards the bottom portion.
Abstract:
A hybrid button according to the invention is provided. In one embodiment, the button can be implemented in an electronic device such as a media player. The button can include a metal or other non-plastic portion having a reverse flange and a plastic portion including anti-rotation legs. The legs can prevent rotation at least in part because they are retained by another structure. The plastic portion can be injection-molded onto the reverse flange of the metal or non-plastic portion. As such, the reverse flange fixes the position of the plastic portion with respect to the metal portion. Finally, the metal portion can include an actuator nub that actuates a switch when the button is depressed.
Abstract:
In order to provide different colors of illumination light to keytops in different areas, there is provided a key sheet 8 having a plurality of pad portions 10, 10, . . . provided on a key base 6 made of a transparent or translucent resin and a plurality of keytops 2 provided on the pad portions 10, 10, . . . , wherein the key base 6 is divided into a plurality of areas 41, 42, and 43 which includes one or a plurality of pad portions 10, 10, . . . ; light-blocking portions 18 are provided to boundary regions between the adjacent areas 4, 4 of the key base 6; at least one illumination-light emitting means arrangement portion 14 is provided so as to correspond to each of the areas 41, 42, and 43; and reflecting means 20 which direct light emitted from illumination-light emitting means toward keytop-formed side are entirely or partially arranged in each of the areas 41, 42, and 43 of the key base 6.
Abstract:
Portable phones are getting a trend that s design and thinner configuration becomes more important. Therefore, in order to meet this demand, the entire key top is made of a thin metal, and a thin resin layer is provided on the back surface of the key top and further letter holes are filled with a resin. According to those, the adhesiveness of the key top is improved as well as improvement of hand feeling. In addition, a printed layer for coloring the letters can be provided on the back surface of the key top.
Abstract:
A method for manufacturing a thin keypad with no seams on a panel surface and such assembly includes the following steps. Inks of different colors are printed onto the surface of a rigid substrate so as to shape panel forms and light-transmitting numerals, letters, symbols, a navigation-key pattern, a dialing pattern and an ending pattern. The panel surface is formed with a plurality of grooves after machining and cutting. Then, inks of different colors are printed onto the surface of a soft substrate so as to form a lining sheet of a light-shielding layer and a reflective layer corresponding to patterns of the panel. The thus-formed panel and lining sheet are disposed into a mold. Rubber is filled in the mold and, after pressing, bound with the bottom of the lining sheet to form a light-guiding layer. At the same time, the light-shielding layer, the reflective layer and the rubber are extruded on the panel surface, so that no seams exist between the keys of the panel surface. Finally, laser is radiated to dot on the light-guiding layer to form thereon light-guiding micro structures having a light-condensing effect.
Abstract:
A key module and its manufacturing method are provided in the present invention. The steps of the method include: providing a mold; forming a key body having multiple opening portions on the mold; jostling a combination of a display body and an elastic body to the key body; and finally, tightly attaching the display body to the key body and stuffing the display body into the opening portions of the key body. Therein, the elastic body has a lower end formed with a contact block contacting a circuit board. By compressing, injecting or infusing a silicone rubber material or an elastic material into the opening portions, the gap located between the key body and the display body or between the key body and the elastic body is smaller than 0.01 mm. Thus, the appearance of the key module of the present invention is almost seamless.
