The subject matter herein generally relates to electronic devices, and more particularly to a composite middle frame of an electronic communication device.
Generally, an electronic communication device includes an enclosed metal middle frame which is an electrostatic screening structure. Signals of the electronic communication device generally require to be transmitted through partition strips arranged on a body of the electronic communication device. However, the partition strips negatively affect an outward appearance of the electronic communication device.
Therefore, there is room for improvement in the art.
Implementations of the present disclosure will now be described, by way of example only, with reference to the attached figures.
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. Additionally, 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. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
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 “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” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
In at least one embodiment, the first connecting layer 101 and the third connecting layer 103 are coupled to the second connecting layer 102 by nano-injection molding. The first connecting layer 101 is coupled to the display screen of the electronic communication device, and the third connecting layer 103 is coupled to the back cover of the electronic communication device. A thickness of the first connecting layer 101 or the third connecting layer 103 is between about 0.5 mm-1.5 mm, and more preferably is about 1.5 mm. A thickness of the second connecting layer 102 is about 2.5 mm-4 mm, and more preferably about 3 mm. The second connecting layer 102 defines a charging hole 106, a speaker hole 107, a power hole 104, and a volume control button hole 105.
The composite middle frame 100 further includes two first side sections 1001 and two second side sections 1002. The two first side sections 1001 and the two second side sections 1002 are interconnected. The two first side sections 1001 are arranged on the outer, opposite sides of middle frame and substantially parallel to each other. The two second side sections 1002 are arranged on the outer, opposite sides of middle frame and substantially parallel to each other. Each first side section 1001 includes a first outer surface 10010 facing away from the other first side section 1001. The first outer surface 10010 extends from the first connecting layer 101 to the third connecting layer 103, and the first outer surface 10010 is substantially a flat surface (shown in
In other embodiments, the number of connecting layers 101-103 can be varied according to requirements. For example, the composite middle frame 100, 200, 300 may include one metal connecting layer and one plastic connecting layer. In other embodiments, the composite middle frame 100, 200, 300 may include two metal connecting layers and two plastic connecting layers alternately layering on each other.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
