1. Technical Field
The exemplary disclosure generally relates to housings, particularly to housings used in electronic devices.
2. Description of Related Art
Many housings, used with electronic devices, include a main body and a transparent screen guard. The main body and the screen guard are manufactured in separate molding processes then glued or otherwise fixed together. Over time the glue or other means may wear and allow dust and moisture to enter the housing, potentially damaging the electronic elements inside. Furthermore, because the main body and the screen guard are made in two separate processes and then connected in a separate step, assembly time is long and complicated and adds to the manufacturing burden.
Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary housing used in an electronic device. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.
Referring to
The base 21 is made of a thermoplastic material such as Polycarbonate (PC), Polymethyl Methacrylate (PMMA), or any combination thereof. The first transparent strengthening layer 23 and the second transparent strengthening layer 24 are for improving the strength of the screen guard 20. The anti-reflection layer 25 is for reducing glare off of the screen guard 20. The shading layer 27 may be an ink film, a paint film, or a metallic film. The main body 40 is made of a thermoplastic material that has a heat-deformation temperature lower than the base 21, such as the combination of Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS). The screen guard 20 has a thickness ranging from about 0.5 millimeters to about 1.5 millimeters, and in this embodiment has a thickness ranging from about 1.0 millimeter to about 1.2 millimeter.
It is to be understood, however, that even through numerous characteristics and advantages of the exemplary disclosure have been set forth in the foregoing description, together with details of the system and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
