AI Technical Summary
Technical Problem
The silver paste circuit of traditional POS machines is prone to break due to the PET substrate and non-tension-resistant silver paste, which causes the power grid wall to close without protection and is less safe.
Method used
TPU substrate and stretchable silver paste are used to form a stretchable silver paste circuit through IMD in-mold injection molding process, and a hole number 1 is set on the TPU substrate. The silicone contacts are connected to the buttons through the holes to ensure that the silver paste circuit is not easily broken during damage.
Benefits of technology
It effectively enhances the protection effect of the POS machine, prevents the power grid wall from being damaged, and improves the safety of the equipment.

Abstract
The utility model discloses an anti-theft silver paste circuit of a POS (Point Of Sale) machine, which comprises a TPU (Thermoplastic Polyurethane) base material provided with a plurality of first holes, stretchable silver paste formed by injection molding with the TPU base material through an IMD (In-mold Deposition) injection molding process, a key formed by injection molding with the TPU base material through an IMD, and a plurality of silica gel contacts formed by injection molding with the key and penetrating through the first holes, the stretchable silver paste is printed in the TPU base material, and the stretchable silver paste is printed in the TPU base material. One end of the silica gel contact extends out of the first hole and then the silica gel contact and the key are located on the two sides of the TPU base material respectively. The POS machine has the advantages that by means of the design of the TPU base material and the stretchable silver paste, when the keys are damaged, the silver circuit is not prone to being pulled apart, a power grid wall generated by the POS machine cannot disappear, the protection effect is achieved, and the protection effect of the POS machine is enhanced.
