Description of the Invention: [Technical Field of the Invention] The present invention relates to an electronic device housing. [Prior Art] With the development of mobile communication technology, a variety of electronic devices such as mobile phones have emerged, enabling consumers to fully enjoy the convenience of mobile = technology at any time and place. More and more: the majority of consumers are favored. The housing is one of the main components of the electronic device, and is widely used in electronic devices such as telephones, calculators, computers, and the like. However, in order to improve the decoration of the electronic chip, the pattern is printed on the casing of the general electronic device. Conventionally, an in-mold decorative process (In_Mold Label, iml) is used to fabricate a patterned electronic device housing. In this way, the pattern is covered by the layer, so that the pattern can be prevented from being worn due to factors such as use. However, for an electronic device housing including a display window, the shrinkage rate of the film layer used for the in-mold decoration process is inconsistent with that of the injection material, and the thin layer and the injection material are injected when the electronic device housing is injection molded. Stress will be generated between them, which will cause birefringence, which affects the light transmission effect of the electronic device housing. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an electronic device housing that can enhance the light transmission effect. An electronic device housing, the housing comprising a film layer and a clamping layer, the film layer comprising a window portion and a connecting portion extending from the window portion, the window portion is formed with a window, the engaging member is formed by The integrally formed 200952594 method is formed on the joint of the film layer. Compared with the prior art, the window of the casing is not combined with the engaging member, so that the stress at the window of the casing is prevented due to the inconsistency of the shrinkage rate of the film layer and the engaging member. Avoid the phenomenon of birefringence at the window to enhance the light transmission effect of the window. [Embodiment] The electronic device casing of the present invention is suitable for use in an electronic device such as a mobile phone, a PDA, or a computer. This embodiment is described by taking a case applied to a mobile phone case as an example. Referring to Figures 1 and 2, the mobile phone 100 includes an upper casing 10 and a lower casing (not shown) that is engaged with the upper casing 10. The upper casing 1 includes a main body 12 and a fitting member 14, and the engaging member 14 is formed on the main body 12 by integral molding. The body 12 includes a film layer 122 and a shielding layer 124. The shielding layer 124 is formed on the film layer ι22. The film layer ι 22 includes a window portion 1222 and a connecting portion 1224 extending from the window portion 1222. The connecting portion 1224 and the window portion 1222 define a cavity 1226. The cavity 1226 is used to house internal components (not shown) of the mobile phone 100, such as a display screen or a motherboard. The shielding layer 124 is formed on the inner side of the film layer 122 to form a window 1228 for display on the window portion 1222 of the film layer 122. The film layer 122 is made of a transparent material such as polymethacrylic acid, polycarbonate, or polyamide. The thickness of the film layer 200952594 122 is preferably 0.5 to 1.5 mm in order to satisfy the requirements of the body 12, "the strength of the beta structure and the thinness of the mobile phone j." The shielding layer 124 is used to form the window 1228 on the film layer 122. That is, the window 1228 is in fact an area on the film layer 122 where the shielding layer 124 is not laminated. Thus, the window 1228 is a light transmissive portion so that the information of the display screen mounted inside the upper casing 10 can be seen. The occlusion layer 124 can be formed by laminating an opaque ink on the film layer 122. The occlusion layer 124 can be a black occlusion layer 124 or a white occlusion layer & 124. The black occlusion layer 124 is made of black such as carbon black or ink. The black opaque ink composed of an inorganic pigment and a resin binder is printed, and the white occlusion layer 124 is printed by a white opaque ink composed of a white metal pigment and a resin binder. The occlusion layer 124 may also be vacuum-coated. It is composed of a metal thin film formed by a method such as vacuum sputtering or ion plating. It can be understood that the shielding layer 124 can be composed of the above-mentioned black blocking ink, white blocking ink and metal film combination. The engaging member 14 includes a frame body 142, a first end edge 144 and a second end edge 146 opposite the first end edge 144. The frame body 142 defines the first end edge 144 and the second end. The first end rim 144 is oriented toward the window portion 1222 of the film layer 122. The second end edge 146 extends a plurality of buckles 1462 for engaging the lower case. The outer side of the body 142 is coupled to the inner side of the connecting portion 1224. The engaging member 14 is formed by injection molding of a transparent plastic. The transparent plastic may be a polyvinyl chloride resin, a polypropylene resin, a polyethylene resin, or a polyethylene terephthalate. Resin, polycarbonate resin, nylon resin, vinylon resin, alkyd resin, polyethylene resin, polyimide resin, polypropylene resin, 200952594 polyvinyl chloride resin, acrylonitrile-styrene-butyl One or more kinds of olefinic copolymers. The plastic layer is not injected on the window portion 1222 of the film layer 122 to enhance the structural strength of the upper shell 10, and the thickness of the film layer 122 is adjusted to meet the upper portion. The structural strength of the shell 10 is required. Thus, due to the window 122 of the upper shell 10 8 pieces of plastic material are not injected, so that the stress at the window 1228 of the upper case 10 due to the inconsistency of the shrinkage rate of the film layer 122 and the plastic can be avoided, thereby avoiding birefringence at the window 1228, thereby enhancing the The light transmissive effect of the window 1228. In summary, the present invention meets the requirements of the invention patent, and the patent application is filed according to law. However, the above is only a preferred embodiment of the present invention, and the scope of the present invention is not implemented as described above. The equivalent modifications or variations made by persons skilled in the art to the spirit of the present invention are intended to be included within the scope of the following claims.
