Plastic casing structure provided with protective circuit, as well as forming die and manufacture method thereof

Abstract

The invention discloses a plastic casing structure provided with a protective circuit, as well as a forming die and a manufacture method thereof. The plastic casing structure provided with the protective circuit comprises a plastic casing body, wherein a thin film layer is arranged on the inner side of the plastic casing body, and comprises an adhesive layer, a base layer, a winding layer and an insulation layer which are arranged sequentially; and the adhesive layer is connected with the plastic casing body. According to the invention, the thin film layer provided with a protective conducting wire is arranged on the inner side of the plastic casing body, so that the production and processing procedure can be simplified, and the manufacturing cost can be reduced. The forming die disclosed by the invention is provided with a positioning mechanism on a punch, quick positioning of the thin film layer is achieved in a locating pin manner, so that the forming processing time of the plastic casing body can be saved. In order to facilitate the quick positioning of the thin film layer, when placed to the punch, the thin film layer is prepressed in a shape matched with the punch through a prefabricate die, so that the thin film layer is no longer integrally formed with the plastic in the forming die; and further, the yield of plastic products is improved, and defective product loss in a production process is reduced.

Description

technical field [0001] The invention relates to a plastic shell structure, its forming mold and manufacturing method, more specifically, a plastic shell structure with a protective circuit, its forming mold and its manufacturing method. Background technique [0002] With the development of electronic technology, human society has entered an information age. More and more important information is transmitted and processed through various electronic devices. However, these electronic devices will inevitably lead to theft or loss due to improper storage. Situation happens. These electronic devices that fall into the hands of others may be disassembled at any time to steal important internal information. In electronic devices such as POS machines, password keyboards, and PDAs, storage devices are required to store related confidential information, such as digital certificates, user information, and the like. However, this type of storage device is often used in an unsafe envir...
