Protection structure for preventing physical intrusion for display screen module group

Abstract

The invention discloses a protection structure for preventing the physical intrusion for a display screen module group, and the structure comprises the display screen module group, a main unit board,a connecting terminal male head, and a connecting terminal female seat. The display screen module group is a display screen of a POS mobile terminal, and the main unit board is a circuit board of thePOS mobile terminal. The connecting terminal female seat is fixedly connected to an upper end face of the main unit board, and the connecting terminal female seat consists of a housing and metal elastic pieces. The central part of the housing is provided with a square port, and the metal elastic pieces are fixedly connected to two sides of the housing. The metal elastic pieces at two sides are setat intervals, and metal terminals at two sides are connected to an anti-dismounting circuit. The connecting terminal male head is shaped like T, and a horizontal segment of the connecting terminal male head is fixedly connected to the back of the display screen module group through foam glue. The connecting terminal male head is vertically inserted into the square port of the housing, and the twosides of the vertical segment of the connecting terminal male head extrude the metal elastic pieces at two sides. The structure is simple, the use effective is good, and the cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of POS mobile terminals, in particular to a protective structure for a display screen module against physical intrusion. Background technique [0002] At present, most POS mobile terminals adopt anti-physical intrusion solutions. This technical method is to set a conductive base and Dome film between the motherboard and the display screen. Through the mutual extrusion of the conductive base and the Dome film, the terminal equipment is guaranteed. The continuous conduction of the security and anti-intrusion system, when the display module is tilted, the Dome chip rebounds, disconnecting the anti-tamper circuit, and the motherboard immediately clears important information, thereby playing a protective role. This solution requires high requirements on the material, size, strength and other characteristics of the display module, conductive base, Dome film and other materials; it requires a series of product design ch...

AI Technical Summary

Problems solved by technology

This solution has high requirements on the material, size, strength and other characteristics of the display module, conductive base, Dome sheet and other materials; it needs to go through a series of product design changes, mold modification, and sample verification to obtain specific data; it will undoubtedly increase Product development cycle, delayed product launch time, etc.
