Embodiments of the present invention relate to an apparatus and a method for use in assembly of a portable apparatus. In particular, they relate to an apparatus and method for use in assembly of a mobile cellular telephone.
Portable apparatus such as mobile cellular telephones usually include a plurality of housing portions that define the exterior of the portable apparatus and thereby provide a cover. The housing portions usually house the electronic components of the portable apparatus and may provide some protection from the environment (for example, rain) and from accidental damage (for example, being dropped by a user of the portable apparatus).
The housing portions are usually fastened to one another via screws. For example, screws may be inserted through apertures in one housing portion and engage a screw aperture in another housing portion. In order to obtain secure fastening of housing portions, apertures may be provided through internal structures within the portable apparatus (for example, the keypad frame). However, this may result in the internal structures becoming mechanically weaker and easier to damage. Alternatively, the housing portions may be increased in size so that the screws may be inserted in locations that are free from internal structures. However, this may result in the portable apparatus becoming undesirably large.
It would therefore be desirable to provide an alternative apparatus and method for use in assembly of a portable apparatus.
According to various, but not necessarily all, embodiments of the invention there is provided an apparatus comprising: a first interconnector portion configured to fasten to a side part of a first housing portion of a portable apparatus, and a second interconnector portion rigidly connected to the first interconnector portion and configured to fasten to a second housing portion of the portable apparatus.
The apparatus may be for use in assembly of a portable apparatus.
According to various, but not necessarily all, embodiments of the invention there is provided an apparatus comprising: means for fastening to a side part of a first housing portion of a portable apparatus, and means for fastening to a second housing portion of the portable apparatus, the means for fastening to the first housing portion being rigidly connected to the means for fastening to the second housing portion.
According to various, but not necessarily all, embodiments of the invention there is provided a portable apparatus comprising the apparatus described in the preceding paragraphs.
According to various, but not necessarily all, embodiments of the invention there is provided a method comprising: fastening a first interconnector portion to a side part of a first housing portion of a portable apparatus, and fastening a second interconnector portion, rigidly connected to the first interconnector portion, to a second housing portion of the portable apparatus.
The method may be for use in assembly of a portable apparatus.
For a better understanding of various examples of embodiments of the present invention reference will now be made by way of example only to the accompanying drawings in which:
In more detail,
In the following description, the wording ‘connect’ and ‘couple’ and their derivatives mean operationally connected/coupled. It should be appreciated that any number or combination of intervening components can exist (including no intervening components).
The first housing portion 12 and the second housing portion 14 may function as a cover for the apparatus 10 and thereby define the exterior surface of the apparatus 10. The first housing portion 12 includes a front part 18 and side parts 20. The front part 18 includes one or more apertures for user input/output devices (for example, a display, a microphone, a loudspeaker, a keypad) and the side parts 20 extend substantially perpendicularly from the perimeter of the front part 18. The second housing portion 14 includes a rear part 22 and side parts 24 that extend substantially perpendicularly from the perimeter of the rear part 22.
The first and second housing portions 12, 14 may comprise any suitable material and may comprise metal and/or plastic. The first and second housing portions 12, 14 may be coated in a protective material. For example, when the first and second housing portions 12, 14 comprise metal, they may be coated with a plastic layer that protects the metal from damage and rust.
The first housing portion 12 and the second housing portion 14 define a cavity 26 and may house electronic components of the portable apparatus 10 within the cavity 26. For example, the first and second housing portions 12, 14 may house a processor and a memory that are mounted on, and connected via a printed circuit board (not illustrated in this figure).
The interconnector 16 includes at least one first interconnector portion 28 and at least one second interconnector portion 30 that are rigidly connected to one another (via a third interconnector portion 32 for example) and are configured to fasten the first and second housing portions 12, 14 together. The interconnector 16 may comprise any suitable material(s) and may comprise metal for example. The various configurations of the first and second interconnector portions 28, 30 are described in more detail with reference to
In this embodiment, the interconnector 16 is positioned wholly within the cavity 26 defined by the first and second housing portions 12, 14. In other embodiments, the interconnector 16 may be positioned partially within the cavity 26. For example, the interconnector 16 may be positioned so that the first interconnector portion 28 is external to the cavity 26 and so that the second interconnector portion 30 is within the cavity 26. Such an embodiment is described in the following paragraphs with reference to
In various embodiments, the interconnector 16 is solely configured to fasten the first and second housing portions 12, 14 together. For example, the interconnector 16 may be a frame that is provided solely for fastening the first and second housing portions 12, 14 together. In other embodiments, the interconnector 16 is configured to provide a function in addition to being configured to fasten the first and second housing portions 12, 14 together. For example, the interconnector 16 may be a keypad frame that is configured to support the keypad and may also be configured to fasten the first and second housing portions 12, 14 together.
The one or more first interconnector portions 28 are configured to fasten to the side parts 20 of the first housing portion 12. The vector of the fastening force 34 provided by the one or more first interconnector portions 28 is substantially perpendicular to the side parts 20 of the first housing portion 12. The one or more second interconnector portions 30 are configured to fasten to the second housing portion 14. The vector of the fastening force 36 provided by the one or more second interconnector portions 30 is substantially perpendicular to the rear part 22 of the second housing portion 14. Consequently, the vectors of the fastening forces provided by the first and second interconnector portions 28 are substantially orthogonal to one another.
A method for assembling an apparatus 10 according to various embodiments of the present invention is described in the following paragraphs with reference to
At block 38, the method includes providing the first housing portion 12, the second housing portion 14 and the interconnector 16. At block 40, the method includes positioning and orienting the interconnector 16 within the first housing portion 12 for fastening thereto. At block 42, the method includes fastening one or more first interconnector portions 28 to the side parts 20 of the first housing portion 12. At block 44, the method includes fastening one or more second interconnector portions 30 to the second housing portion 14.
The above described method of assembly may provide a portable apparatus 10 that has a substantially rigid cover formed from the first housing portion 12 and the second housing portion 14. Blocks 42 and 44 may be performed using specialist manufacturing tools that are only accessible to the manufacturer. Consequently, the user of the portable apparatus may not be able to disassemble and assemble the portable apparatus.
The illustration of a particular order to the above blocks does not necessarily imply that there is a required or preferred order for the blocks and the order and arrangement of the block may be varied. Furthermore, it may be possible for some blocks to be omitted.
Embodiments of the present invention may provide an advantage in that the first and second housing portions 12, 14 are fastened to one another via the interconnector 16. Consequently, any structures (for example, a keypad frame) which are positioned between the interconnector 16 and the front part 18 may not require any apertures for fasteners (such as screws). Therefore, embodiments of the present invention may provide a portable apparatus that has relatively rigid internal structures and is relatively narrow in comparison with other portable apparatus.
In this embodiment, the interconnector 16 comprises a substantially planar keypad frame 32 that rigidly connects cam receiving members 28 (the first interconnector portions) and screw receiving members 30 (the second interconnector portions). The cam receiving members 28 include an aperture 48 for receiving a cam and an aperture 50 for receiving a fastener (a grub screw for example) for fixing a cam in place in the cam aperture 48. The keypad frame 32 is substantially rectangular and the cam receiving members 28 are positioned around the perimeter of the keypad frame 32 along the two short edges. The screw receiving members 30 are positioned adjacent the cam receiving members 28.
The side parts 20 of the first housing portion 12 include cam receiving apertures 46. In assembly of the apparatus 10, the interconnector 16 is positioned within the first housing portion 12 so that the cam receiving apertures 46 of the side parts 20 are lined up with the cam receiving members 28. Cams 52 are then inserted through the cam receiving apertures 46 of the side parts 20 and into the apertures 48 of the cam receiving members 28. As illustrated in
With reference to
In this embodiment, the interconnector 16 comprises a substantially planar frame that is solely provided for fastening the first and second housing portions 12, 14 together. The frame 16 is substantially rectangular and defines a substantially rectangular aperture 60. The frame 16 includes screw receiving members 28 (the first interconnector portions) that provide the two short edges of the frame 16 and include a plurality of apertures for receiving screws. The frame 16 also includes screw receiving members 30 (the second interconnector portions) that are positioned adjacent the screw receiving members 28. The screw receiving members 28, 30 are rigidly connected to one another via frame portions 32 which provide the long edges of the frame 16.
The side parts 20 of the first housing portion 12 include screw receiving apertures 62. In assembly of the apparatus 10, the frame 16 is positioned within the first housing portion 12 so that it is adjacent a printed circuit board 63 housed with the first housing portion 12 and so that the screw receiving apertures 62 of the side parts 20 are lined up with the apertures of the screw receiving members 28. Additionally, the frame 16 is oriented substantially parallel with the printed circuit board 63. Screws 64 are then inserted through the apertures 62 of the side parts 20 and into the screw receiving members 28. The screws 64 are then rotated in order to fasten the first housing portion 12 and the frame 16 together. The second housing portion 14 may then be fastened to the frame 16 as described above with reference to
The embodiment illustrated in
In this embodiment, the apparatus 10 includes two interconnectors 16 that each include a bracket 28 (the first interconnector portion) and three screw receiving members 30 (second interconnector portions) that extend perpendicularly from the bracket 28. It should be appreciated that in other embodiments, the apparatus 10 may include any number of interconnectors 16 and each interconnector 16 may include one or more screw receiving members 30.
The side parts 20 of the first housing portion 12 include apertures 66. In assembly of the apparatus 10, the screw receiving members 30 are inserted into the apertures 66 until the brackets 28 abut an exterior surface 68 of the side parts 20. The screw receiving members 30 are thereby positioned within the first housing portion 12 so that they are adjacent a printed circuit board 63 housed within the first housing portion 12. The second housing portion 14 may then be fastened to the frame 16 as described above with reference to
It should be understood that in this embodiment the brackets 28 fasten to the side parts 20 of the first housing portion 12 through their abutment with the exterior surface 68 of the side parts 20. Additionally, screws (not illustrated) may be used to secure the brackets 28 to the side parts 20 the first housing portion 12.
As with the embodiment illustrated in
Since the screw receiving members 30 are positioned between the printed circuit board 63 and the rear part 22 of the second housing portion 14, the printed circuit board 63 does not include any apertures for receiving the screws 58. This may advantageously result in a printed circuit board 63 having a greater useable surface area.
Although embodiments of the present invention have been described in the preceding paragraphs with reference to various examples, it should be appreciated that modifications to the examples given can be made without departing from the scope of the invention as claimed. For example, the first interconnector portion 28 may be a fastener receiving member and the second interconnector portion 30 may be a bracket. Furthermore, the interconnector 16 may have any shape.
The portable apparatus 10 may be configured it receive a battery on the exterior surface of the rear part 22 of the second housing portion 14. In this embodiment, the rear part 22 does not provide an exterior surface of the portable apparatus 10 since a third housing portion is then provided to cover the battery.
