本文系从实际应用出发,比较集中地论述了在计算机从逻辑图转换成硬件实体的工程化设计中普遍采用的三级(即器件级、插件级和背板级)装联的结构特点以及各类接插件在各级组装互连中所起的作用及其重要性。文中所论及的接插件大多是近年来为顺应当今计算机高技术发展之需求而开发成功的新品类。尤其是与LSI及VLSI器件(如Intel公司的32位cpu—80386)配用的各类应栅阵列式插座(PGA插座)以及专用于各类表面封装式(有引线或无引线)器件的新结构插座在新一代的计算机和其它电子系统中获得了广泛的应用。此外,本文还对印制背板用的高密度表面安装式边缘连接器和当前国际上电连接器中结构独特、性能优异的高可靠的单叶回转双曲面线簧插孔连接器的结构原理及主要性能亦作了细详阐述。故本文对从事计算机和其它电子系统的装联设计的工程技术人员颇有参考价值。
Based on the practical application, this dissertation focuses on the structural features of the three-stage (ie, device level, plug-in level and backplane level) assembly commonly used in the engineering design of computer from logic diagram to hardware entity, The role and importance of connectors in the assembly and interconnection at all levels. Most of the connectors discussed in this paper are new products developed in recent years to meet the demands of today’s high-tech development of computers. In particular, various types of pin array (PGA) sockets for use with LSI and VLSI devices such as Intel’s 32-bit CPU-80386, as well as new dedicated devices for various types of surface-mount (leaded or leadless) Structure socket in a new generation of computers and other electronic systems has been widely used. In addition, the paper also printed on the backplane with high-density surface-mount edge connector and the current international electrical connectors unique structure, high performance and reliability of the single leaf swivel hyperboloid wire spring jack connector structure principle The main features are also described in detail. Therefore, this article engaged in computer and other electronic systems design of the assembly and installation of engineering and technical personnel of considerable reference value.
