DETAILED DESCRIPTION
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “outside” refers to a region that is beyond the outermost confines of a physical object. The term “inside” indicates that at least a portion of a region is partially contained within a boundary formed by the object. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
FIG. 1 illustrates a housing 100 for portable electronic device such as mobile phones and tablet computers. In the embodiment, the housing 100 is shown as a back cover of a mobile phone. The housing 100 comprises a first section 10 substantially composed of metal and a second section 20 substantially composed of dielectric ceramic. The second section 20 is coupled to the first section 10 to cooperatively define an accommodating space 104.
In the exemplary embodiment, the first section 10 and the second section 20 are two separate parts coupled together. In other embodiments, the first section 10 and the second section 20 can be integrally formed together.
FIG. 4 illustrates that the housing 100 further comprises an antenna 30 coupled to the second section 20. The second section 20 comprises a main portion 21 and a latching portion 22 extending from the main portion 21, the latching portion 22 is coupled to the first section 10. The antenna 30 is coupled to an inner surface 211 of the main portion 21 facing the accommodating space 104. The antenna 30 can be conductive material formed on the main portion 21. The conductive material can be but is not limited to conductive ink and conductive metal. The conductive material can be formed on the main portion 21 by any known feasible method for forming such a conductive material on a substrate made of dielectric ceramic. The antenna 30 can transmit and receive signals through the main portion 21 since the second section 20 is made of dielectric ceramic.
FIG. 3 illustrates that the first section 10 defines at least one latching recess 121 and the latching portion 22 comprises at least one latching protrusion 224. The at least one latching protrusion 224 is latched in the at least one latching recess 121 (best shown in FIG. 6). The at least one latching recess 121 and the at least one latching protrusion 224 are triangular shaped. In the exemplary embodiment, the first section 10 defines two latching recesses 121 and the latching portion 22 comprises two latching protrusions 224. The first section 10 comprises an end surface 103 of an end coupled to the second section 20.
FIG. 4 illustrates that a step portion 23 is formed at an end of the main portion 21 connected to the latching portion 22, thereby forming a stepped exterior periphery 201 of the second section 20. FIGS. 2 and 5 illustrate that the end surface 103 resists and is aligned with the step portion 23, allowing a first outer surface 212 of the main portion 21 to be coplanar with a second outer surface 102 of the second section 20.
The first section 10 further comprises a board portion 11 and two side walls 12 extending substantially perpendicularly from opposite sides of the board portion 11. The at least one latching recess 121 is defined in an internal surface 120 of at least one of the two side walls 12 facing the accommodating space 104.
FIGS. 4 and 6 illustrate that the latching portion 22 comprises a connecting portion 221 and two latching walls 223 connected to opposite ends of the connecting portion 221. The two latching walls 223 are substantially perpendicular to the connecting portion 221. The at least one latching protrusion 224 protrudes from at least one of the two latching walls 223. The latching portion 22 is received in the accommodating space 104 with the connecting portion 221 abutting the board portion 11 and the two latching walls 223 abutting the two side walls 12.
FIG. 7 illustrates an embodiment of a portable electronic device 300 incorporating the housing 100. The portable electronic device 300 comprises a main body 200 and the housing 100 assembled to and casing the main body 200. housing 100 comprises the first section 10, the second section 20, and the antenna 30. The main body 200 can have a plurality of components for carrying out functions of the portable electronic device 300. The antenna 30 is connectable to at least one of the components of the electronic device. The components comprise a receiver 201, an display screen 202, and buttons 203, for example.
