Detailed Description

Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It is to be understood that the invention is capable of other and different embodiments and its several details are capable of modification without departing from the scope of the invention, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

As shown in fig. 1-7, a high-security keyboard with encrypted package includes an alloy panel 1 and an alloy bottom case 2, a card reading area 3 and a plurality of keycaps 4 are disposed on the alloy panel 1, a keyboard main board 5 and a card reading main board 6 are disposed at the bottom of the alloy panel 1, and a plurality of bolt seats 7 are welded on the alloy bottom case 2, a space capable of accommodating the keyboard main board 5 and the card reading main board 6 is formed on the alloy bottom case 2, the alloy bottom case 2 is provided with a plurality of through holes matched with the bolt seats 7, the alloy bottom case 2 is connected with the alloy panel 1 after being connected with the bolt seats 7 through first bolts 8, wherein a normally-closed switch 9 is disposed in any bolt seat 7, and the normally-closed switch 9, a single chip of the card reading main board 6, and a power supply 10 form a series circuit.

A quincuncial hole 81 is formed at a head portion of the first bolt 8, and a breakage preventing pin 82 which does not contact an inner wall of the quincuncial hole 81 is formed in the quincuncial hole 81. The quincunx holes 81 may be custom shaped to prevent the first bolt 8 from being disassembled by conventional tools and, in the case of providing a breakage-proof cotter, to prevent violent disassembly.

The length and width of alloy panel 1 are greater than those of alloy bottom case 2. The keyboard can be directly placed on the integrated automatic teller machine or business self-service machine, a window is arranged on the automatic teller machine or business self-service machine, and then the keyboard is directly placed.

The edge of the alloy panel 1 is lapped on a mounting window 13 of an alloy bracket 12. The bottom of the alloy bottom case 2 is provided with a second bolt extending downwards, the alloy bottom case 2 is connected with a fixing plate 14 through the second bolt, and the length and the width of the fixing plate 14 are greater than those of the mounting window 13.
