Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 The schematic block diagram of the safety line box is shown and figure 2 As shown in the schematic diagram of the safety circuit box, the safety circuit box includes a casing, the casing includes a bottom plate 1, and the inside of the bottom plate 1 is provided with a trigger circuit board 2, and the trigger circuit board 2 is integrally formed with the bottom plate 1, and also includes an alarm device 3 , the alarm device 3 is connected to the trigger circuit board 2, when the base plate 1 is damaged, the trigger circuit board 2 is disconnected, and the alarm device alarms 3. The trigger circuit board 2 is injection molded together with the casing 1 through the IMD process. The trigger circuit board 2 adopts PET printed circuit, and the resin 8 is injected onto the prepared trigger circuit board 2, so that the resin...

Abstract

The invention discloses a safety circuit box, a POS machine and a method for manufacturing the safety circuit box. The safety circuit box comprises a housing. The housing comprises a bottom plate. Thebottom plate is internally provided with a trigger circuit board. The trigger circuit board and the bottom plate are integrated. The trigger circuit board is connected with an alarm device. Once thebottom plate is damaged, the trigger circuit board is disconnected, and the alarm device gives an alarm. A POS machine card slot cover is provided with the bottom board, thereby preventing lawbreakersfrom demolishing the bottom plate and obtaining the PCB main board. The method for manufacturing the safety circuit box comprises the following steps: preparing a die for molding the bottom plate; preparing the trigger circuit board through a PET printed circuit; placing an IMD film and the trigger circuit board in the die, the IMD film being in the first layer and the printing layer trigger circuit board being placed in the second layer; and injecting resin to the printing layer and extruding the die, and carrying out resin curing, the bottom plate and the trigger circuit board being integrated, thereby reducing installation space and enabling the trigger circuit board and the bottom plate not to be separated easily.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a safety circuit box, a POS machine and a method for manufacturing the safety circuit box. Background technique [0002] At present, the safety anti-dismantlement device adopts the thin film conductor winding layer attached to the inside of the shell, and the attached winding layer has poor fixing performance and is easy to remove. [0003] The original POS machine card slot cover is not designed to protect the circuit. The main reason is that the PET printed circuit is not resistant to deformation and high temperature injection molding. However, the internal PCB of the POS machine is closely related to the card slot cover. In order to prevent criminals from dismantling the POS machine and stealing user information, POS machine designers are required to strictly protect the POS machine PCB main board. [0004] At present, IMD technology is mostly used in mobile phone casings, car sign...
