Description

Technical Field

[0001] The utility model relates to the technical field of single-chip computers, in particular to a single-chip computer protective shell and a single-chip computer. Background Art

[0002] A single-chip microcomputer is an integrated circuit chip. It is a small and complete microcomputer system that integrates the central processing unit CPU with data processing capabilities, random access memory RAM, read-only memory ROM, timer, counter and other functions on a silicon chip using ultra-large-scale integrated circuit technology. When installing existing single-chip microcomputers, the single-chip microcomputer is usually installed inside a housing, so that it can be installed on the chip board for installation and use. However, in the prior art, the shape of the single-chip microcomputer protective shell is composed of two concave protective shells fixedly connected and combined, and the two concave protective shells are usually fixed and installed by fasteners such as screws when they are fixedly installed. This results in the need to use tools to disassemble and assemble one by one during disassembly, which reduces the disassembly and assembly efficiency of the protective shell.

[0003] Therefore, we propose a single-chip microcomputer protective shell and a single-chip microcomputer. Utility Model Content
