Description

Technical Field

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

[0002] A single-chip microcomputer is an integrated circuit chip that uses very large-scale integrated circuit technology to integrate a central processing unit CPU with data processing capabilities, random access memory RAM, read-only memory ROM, multiple I / O ports and interrupt systems, timers / counters and other functions (may also include display driver circuits, pulse width modulation circuits, analog multiplexers, A / D converters and other circuits) onto a silicon chip to form a small and complete microcomputer system. It is widely used in the field of industrial control.

[0003] The Chinese patent discloses a PLC single-chip computer with a protective function (authorization announcement number: CN218298932U). It uses a buffer spring, a mounting base, a limit block and a mounting mechanism. The mounting mechanism can fix the PLC single-chip computer on the top of the mounting base. The use of four buffer springs can play a shock-absorbing role when the PLC single-chip computer is shaken by collision, thereby avoiding wear caused by vibration. The use of four limit blocks plays a role of limit protection and has the ability to reduce shock when it is collided. Although the above-mentioned single-chip computer can play a shock-absorbing role through the buffer spring, since the plug interface on the single-chip computer needs to be connected to an external plug, when the single-chip computer is subjected to force, although it can be shock-absorbed by the spring, it will also shake, which may easily lead to the connection between the plug interface and the external plug being not stable enough. In severe cases, the plug interface and the external plug may fall off, thereby affecting the normal use of the single-chip computer. Utility Model Content

[0020] The four corners at the top of the base 4 are all equipped with a card connector 6, which includes a mounting seat 61, a limiting groove 62 and a clamping rod 63.
