page 1,OUTLINE,Introduction of Crimp Connection Technology 端子压接技术介绍 Introduction of Water Proof Test for a Sealed Connector 密封接插件防水测试介绍 Introduction of Connector/Contact/Seal Application Spec. 接插件/端子/密封件应用规范介绍 Introduction of cable design The SWS must be aligned with the contact centerline. 确保SWS被端子包筒包牢；避免SWS被刺破 SWS 中心须与端子中心对齐,,,,The seal crimped onto the contact is inserted into the cavity. The difference between the dia. of the lips of the SWS and the cavity dia. provides compression on the silicone which generates two additional effects: Friction when the contact is inserted into the cavity Additional closure pressure on the wire interface 装入SWS, 通过对硅胶的压缩达到密封功能,,,Cavity Plugs are used to seal unused cavities with a distance to the top. 未用孔位使用盲堵密封,确保与HSG端面有一段距离,,Cavity Plug,,,Small Tip 1: to find out on a connector drawing we provided 查找接插件图纸,Other useful info. could also be found: Suitable contact for this connector Suitable wire range for this connector Counter part Mating components for this connector 其他有用信息如： 接插件端子，适用线径范围，对配件， 其他各种组件通常亦可在图纸上找到,Small Tip 2: to find out on a contact drawing/ catalog we provided 查找端子图纸或产品目录手册,Suitable SWS indicated on terminal drawing,,,Suitable SWS indicated on product catalog,,,How to Find Suitable SWS for a Connector? 如何找接插件对应的密封圈?,Small Tip 3: to find out on related 114 spec 查找端子使用规范,How to Find Suitable SWS for a Connector? 如何找接插件对应的密封圈?,Family seal,Polarization plate,Longitudinal section,,,,,The family seal must be integrated into the connector. Family seal 通常是预先组装在接插件里 The polarization plate is necessary to guide the contact. Family seal保护盖可用于端子导向,Family Seal and Usable Contacts,,Seal Plug,,Family Seal,MQS clean body,MQS std version,The contact suitable for a grommet must be free of any cut (sharp) edges in all profiles design and stamping process are more complex. 用于Family seal的端子表面不能有任何的尖刃，以免割破密封圈。

这种端子称为Clean body,Family Seal and Usable Contacts Family Seal和所适用端子,Design Considerations: Contact front area / min wire diameter Cavity seal profile (number of lips) Housing interface Poka Yoke assembly features,Family Seal and Usable Contacts,,Sealing of contact cavities,,Wire sealing,Family Seal and Usable Contacts Family Seal和所适用端子,,,A peripheral seal is an element that is used to ensure water-tightness between female and male connectors or female connectors and ECU interfaces Peripheral Seal 用于接插件公端与母端之间的密封，以及母端与ECU接口之间的密封,page 71,,,Small tip: pay attention to the orientation of a Contact before inserting into connector. 插端子前请注意端子的方向，避免误插,page 72,Small tip: Insert terminal until an audible “click” is heard or felt 小心插入端子，直至听到或感受到“咔嗒”声,page 73,page 74,,,Connector Product Specification Functional Requirements Test requirements Test Procedure Application Specification Assembly Instruction,Terminal Product Specification Ratings Electrical Mechanical Application Environment Plating Application Specification Crimp Spec Seal Selection,page 75,导线设计选型和分类,导线类型的选择 依据安装位置工作状态下 的温区特性，选择相应温度特 性导线,page 76,导线设计选型和分类,导线线径的选择,page 77,导线设计选型和分类,导线类型的选择 选用导线时需注意： 保险丝的熔断电流必须低于 导线达到燃烧时的最大电流。

page 78,导线设计选型和分类,导线类型的选择 依考虑导线的适应性（如柔性)，电磁特性选择 绞合、屏蔽导线page 79,导线设计选型和分类,导线类型的选择 导线选择需要考虑有些用电器的电 压降，电路电阻要求page 80,线束设计原理与优化,常用线束保护件选取： 覆盖材料选择要考虑温度等级、耐热、降噪、耐磨等技术要求：,page 81,线束布置和路径走向要求,防止与周围部件干涉： 与关键零件保持一定距离；尽量避免高温等恶劣环境；弱信号传感器线与电源线保持一定距离，避免平行； 装配性和维修性： 易装配，易操作，装配时间短；固定支架的数量和位置 ； 外观： 线束走向整齐美观；接插件，防护具，固定件色调一致；,page 82,线束布置和路径走向要求,防振动要求： 由于发动机的工作工况下振动剧烈，布线的安装点务必确保固定牢靠 固定点位置选择要求为： --固定线束靠近车体上以防止噪音 --线束直的部分固定卡子设计距离200250mm；弯曲部分距离150200mm --利用长槽孔卡子固定并保持线束方向 --距离运动部件至少20mmpage 83,线束布置和路径走向要求,美观要求： 线束走向美观性很大程度上取决于和发动机缸体的同步设计。

建议： 设计发动机缸体时，同时考虑布线要求； 将线束的走向路径预埋到缸体上，减少外露线束； 布线走向整齐，避免交叉和悬空；,page 84,Thank you!,。
