PCB fixing and redundancy connection structure of integration circuit chip capable of repeat plugging

Abstract

The present invention provides a PCB fixing and redundancy connection structure of an integration circuit chip capable of repeat plugging. The structure comprises an integration circuit tube socket with a latching function, two flexible circuit boards, two 90-degree single-row bending head plugging buses and two 90-degree single-row bending head insertion pins. The integration circuit tube socketis welded on the PCB and is configured to fix the integration circuit; the two ends of the integration circuit tube socket are respectively connected with the two flexible circuit boards, the other ends of the flexible circuit boards are connected with the heading end ends of the two 90-degree single-row bending head insertion pins, the other ends of the two 90-degree single-row bending head insertion pins are plugged with the 90-degree single-row bending head plugging buses, and the 90-degree single-row bending head plugging buses are welded on the PCB. The PCB fixing and redundancy connection structure is reasonable in layout and design, employs the dual-directional redundancy connection technology to eliminate bad contact of pin signals of the integration circuit caused by vibration oftransverse and vertical directions, and employs the redundancy connection technology of signal transmission to ensure the reliable connection of the pins of the integration circuit and the PCB.

Description

technical field [0001] The invention belongs to the technical field of electronic control of military armored vehicles, and in particular relates to a PCB fixing and redundant connection structure for re-pluggable integrated circuit chips. Background technique [0002] All-weather and all-region are the basic requirements for the environmental adaptability of military armored vehicles. All electronic control products equipped on military armored vehicles are always faced with possible shock and vibration due to the road environment. Strong shocks and vibrations often lead to poor contact between some non-welded integrated circuit chips and the motherboard PCB signal, resulting in the failure of the control function of electronic control products. It is particularly important to carry out anti-vibration design on key chips of electronic control products. [0003] The integrated circuits installed on the PCB of electronic control products are roughly divided into two types, o...

AI Technical Summary

Problems solved by technology

[0003] The integrated circuits installed on the PCB of electronic control products are roughly divided into two types, one can be directly soldered to the PCB, and its anti-vibration ability is strong; the other is due to the confidentiality of intellectual property rights, and cannot be directly soldered to the PCB. The program chip needs to be connected by a re-pluggable tube socket, which has weak anti-vibration ability

[0004] The traditional method of PCB fixing of re-pluggable integrated circuit chips adopts a single integrated circuit socket connection method. This connection method only relies on the locking pressure of the socket's own locking device to ensure contact reliability, but due to Without welding, it is difficult to ensure reliable contact between the IC pins and the socket
