详细说明：ARINC429总线协议又称ARINC是美国航空电子工程委员会(Airlines Electronic Engineering Committee)于1977年7月提出的，并于同年节月发表并获得批准使用。它的全称是数字式信息传输系统DITS。协议标准规定了航空电子设备及有关系统间的数字信息传输要求。ARINC429广泛应用在先进的民航客机中，如B-737、B757、B-767，俄制军用飞机也选用了类似的技术。我们与之对应的标准是HB6096-SZ-01。Copyright 2002 AERONAUTICAL RADIO INC 2551 Riva road Annapolis, Maryland 24101-7465 USa ARINC SPECIFICATION 404B CONNECTORS.

Today, the major U.S. airlines remain the Companys principal shareholders. Other shareholders include a number of non-US airlines and other aircraft operators ARINC Sponsors aviation industry committees and participates in related industry activities that benefit aviation at large by providing technical leadership and guidance and frequency management. These activities directly support airline goals: promote safety, efficiency, regularity, and cost-effectiveness in aircraft operations The Airlines Electronic Engineering Committee(AEEC) is an international body of airline technical professionals that leads the development of technical standards for airbome electronic equipment- including avionics and in-flight entertainment equipment-used in commercial, military, and business aviation. The AEEC establishes consensus-based, voluntary form, fit, function, and interface standard that are published by arinc and are known as ARINc Standards. The use of arinc Standards results in substantial benefits to airlines by allowing avionics interchangeability and commonality and reducing avionics cost by promoting competition There are three classes of arinc standards a) ARINC Characteristics-Define the form, fit, function, and interfaces of avionics and other airline electronic equipment. aRiNC Characteristics indicate to prospective manufacturers of airline electronic equipment the considered and coordinated opinion of the airline technical community concerning the requisites of new equipment including standardized physical and electrical characteristics to foster interchangeability and competition b) ARINC Specifications---Are principally used to define either the physical packaging or mounting of avionics equipment, data communication standards, or a high-level computer language c)ARINC Reports--Provide guidelines or general information found by the airlines to be good practices, often related to avionics maintenance and support The release of an ARINC Standard does not obligate any airline or arinc to purchase equipment so described, nor does it establish or indicate recognition or the existence of an operational requirement for such equipment, nor does it constitute endorsement of any manufacturer's product designed or built to meet the arinc standard In order to facilitate the continuous product improvement of this arinc Standard two items are included in the back of this volume a) An Errata report solicits any corrections to the text or diagrams in this arinc Standard b) An ARINC IA Project Initiation/Modification(APIM) form solicits any recommendations for addition of substantive material to this volume which would be the subject of a new Supplement ARINC SPECIFICATION ARINC 404B TABLE

INTRODUCTION 1. 1 Purpose 1.7 Wire Range Accommodations This document defines standardized connectors intended Wire range accommodations of the contacts should be as for use on rack-mountable avionics equipment. It shown in Table I incorporates changes to MIL-C-81659 that have taken place since ARiNC Specification 404A was published in 1974. These changes have not affected the form, fit or Table 1-wire range accommodations function of the connectors. In addition, new avionics installations on commercial aircraft are requiring the use of connectors that provide emi protection. These emi WIRE INSULATION requirements have been added to this specification BARREL WIRE DIAMETER RANGE SIZES SIZE (INCH) ARINC Specification 404B contains provisions for th connectors along with Appendices a and b that define the 26.24.22 connector insert arrangements and the connector keying 030to.054 layouts, respectively. In addition, there is a series of 12 connector drawings defining the dimensional 20 24.22.20 040to.071 configuration of the four basic shell sizes for plugs, receptacles and plugs with EMI capability.
