Patent Application
20110233220
This application is one of the four related co-pending U.S. patent applications listed below. All listed applications have the same assignee and were concurrently filed herewith. The disclosure of each of the listed applications is incorporated by reference into all the other listed applications.
1. Technical Field
The present disclosure relates to housings for electronic devices and method for making the housings.
2. Description of Related Art
Typically, an electronic device housing includes a number of portions. The portions can be assembled together with latching members. However, the structures of these housings are complicated due to the latching members, and gaps usually exist at the junctions of the portions. Therefore, dust or other contaminants may easily enter into the housing through these gaps.
Therefore, there is room for improvement within the art.
Many aspects of the housing for electronic devices and method for making the housing can be better understood with reference to the following figures. The components in the figures are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the housing for electronic devices and method for making the housing. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views.
The main body 10 may be a hollow sleeve, and includes a first sidewall 101, a second sidewall 103 opposite to the first sidewall 101, two connecting walls 102 connecting the first sidewall 101 to the second sidewall 103, and a top wall 104. The first sidewall 101, the connecting walls 102, the second sidewall 103, and the top wall 104 are integrally formed with each other and cooperatively define a receiving chamber 105. The main body 10 defines an open end 106 opening the receiving chamber 105. The receiving chamber 105 receives an electronic module (not shown).
Referring to
The decorative layer 13 is formed on an outer surface 114 of the first molded article 11. The decorative layer 13 may be made of ink, paint, or metal coating. The metal coating can be a non-conductive vacuum coating.
The second molded article 15 is formed on the decorative layer 13 and filled in the display window hole 112. Thus, a transparent window 152 is formed in the display window hole 112. The second molded article 15 may be made of a transparent moldable plastic. The transparent moldable plastic may be one or more thermoplastic materials selected from a group consisting of polycarbonate, acrylonitrile-butadiene-styrene, polymethyl methacrylate), butylene terephthalate, and phenylene sulfide.
The cover 20 may be made of plastic or metal, and seals to the open end 106, such as by adhesive.
An exemplary embodiment of a method for making the housing 100 may include the following steps:
Referring to
The first cavity 53 define a first recess 532. When the first mold 50 is to be closed, the first protrusion512 is received in the first recess 532 to define a first mold chamber 57. The first positioning mechanism 54 includes a first positioning post 541 and a first hole 543 receiving the first positioning post 541. The first positioning post 541 is mounted on the bottom portion 533 of the first cavity 53 opposing the first top portion 5122. The first hole 543 is defined in the first top portion 5122. The first mold 50 includes at least two first gates 56 defined between the first core 51 and the first cavity 53 when the first mold 50 is closed. When the first mold 50 is closed, the first positioning post 541 is inserted into the first hole 543 to prevent the first protrusion512 deviating from the first cavity 53.
Referring to
Referring to
In other exemplary embodiments, the first hole 543 can be defined in the first cavity 53. Correspondingly, the first positioning post 541 is mounted on the first top portion 5122.
In other exemplary embodiments, the decorative layer 13 can be omitted when the first molded article 11 has the required color. Thus, the second molded article 15 is directly connected to the first molded article 11.
In other exemplary embodiments, the decorative layer 13 also can be coated by a transparent protective layer to prevent the decorative layer 13 being scratched. The transparent protective layer is sandwiched between the decorative layer 13 and the first molded article 11
It should be understood, however, that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, 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 present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
