Referring to fig. 1 to 3, fig. 1 to 3 disclose a novel terminal rear cover, which includes a rear cover body 1, a connecting member 2, an outer surface layer 13 and an inner surface layer 14, wherein the rear cover body 1 and a rear shell 12 are integrally formed, the rear cover body 1 is also deficient in transparency and smoothness, and the rear cover body 1 needs to be surface-treated due to the characteristics of the material and the requirements of the user during the use process, and the outer surface layer 13 is directly perceived and touched by the user, so the treatment of the outer surface layer 13 is particularly important Polybutylene terephthalate, thermoplastic resin and the like, and the hardness of the outer surface of the rear cover body 1 can reach 2H-3H; and for the surface, the processing selectability of the internal surface of back lid body 1 is just a bit more relatively, because the internal surface of back lid body 1 has just lacked the sense of touch experience for the user, consequently, the processing of the internal surface of back lid body 1 can be realized for the mode of spraying paint, direct coating film or pad pasting, just that the utility model discloses an internal layer 14. The rear cover body 1 is formed by stirring PC and PMMA materials with components in a preset proportion and then performing injection molding through a compression mold, the raw materials of the PC and the PMMA are granular, so the stirring is only performed in a container according to the preset proportion, and the stirring is not completely uniform; the connecting piece 2 is arranged at the edge of the inner surface of the rear cover body 1, the function of the connecting piece 2 is the same as that of the traditional connecting piece 2, but the integration requirement of the utility model can be considered, the traditional connecting piece 2 and the rear cover body 1 can be integrally formed, or separately processed, and then the connecting piece 2 and the rear cover body 1 are connected by sticking and other modes; if the rear cover body 1 and the connecting piece 2 are integrally formed, the plastic mold can adopt a slide structure, an oblique top structure and other structures to realize the characteristics of the holes on the side surfaces of the connecting piece 2 and the rear cover body 1, and the slide structure, the oblique top structure and other structures can leave marks on the rear cover body 1 (the marks left by the slide structure and the oblique top structure cannot be solved in the industry of the existing plastic mold and can only be eliminated through subsequent polishing, so that a lot of workload can be increased), and because the material adopted by the utility model has good transparency, the marks left by the slide structure and the oblique top structure can only be eliminated through subsequent polishing, so the plastic mold is separately processed and then bonded, and the plastic mold is more convenient; of course, the elimination of the forming mode of slide and inclined top requires that after the compression mold injection molding of the back cover body 1, a CNC (computer numerical control) device or other device is used to machine through holes, such as speaker holes, headphone jacks and the like, on the upper side surface of the back cover body 1; the outer surface layer 13 covers the outer surface of the rear cover body 1, and the inner surface layer 14 covers the inner surface of the rear cover body 1. Adopt above-mentioned structure, the utility model discloses a back lid effect of transparent integration of entire body.

The PC is a polycarbonate (abbreviated as PC) which is a high polymer having a carbonate group in a molecular chain, and has advantages of strength, elastic coefficient, high impact strength, high transparency, free dyeing property, low molding shrinkage, good dimensional stability, and the like.

It should be noted that the PMMA (Polymethyl methacrylate) is a transparent polymer material generally called organic glass and is Polymethyl methacrylate, and has the advantages of good transparency, chemical stability, mechanical properties, weather resistance, easy dyeing, easy processing, beautiful appearance and the like.

Further, the ratio of the PC to the PMMA is 7: 3.

specifically, with reference to actual requirements, the ratio of PC to PMMA is 7: 3, which may also vary slightly in said ratio, such as 6: 4/7.5: 2.5 is also possible, only by inspection and practical use, 7: 3 is the optimum ratio.

Further, the connecting piece 2 is adhered to the edge of the inner surface of the rear cover body 1 by glue.
