标准摘要
[中文适用范围]： 该 SAE 标准规定了卡车拖车跨接电缆系统的高功率两导体跨接电缆插头和插座的最低要求。它包括测试程序@设计@和性能要求。本文件涵盖额定电流超过 30A（安培）直至 150A 的插座，适用于具有一根电源线和一根公共回路线的单一电路。不建议在未来的设计中使用单导体高电流连接器，因为通过第五轮/主销的接地回路不充分。电缆尺寸选择由车辆 OEM 针对特定应用以及这些应用的特定压降要求进行选择。该 SAE 标准涵盖高功率两导体连接的两种变体：具有水平对齐引脚的重型版本，通常用于提升门电池充电；以及具有垂直对齐引脚的中型版本：通常用于电力防水布等负载。 [外文原描述]： This SAE Standard provides the minimum requirements for high-power, two-conductor jumper cable plug and receptacle for truck-trailer jumper cable systems. It includes the test procedures, design, and performance requirements. This document covers receptacles rated 12 VDC nominal and at more than 30 A (amperes) up to and including 150 A, and is intended for a single circuit with one power conductor and one common return conductor. Single-conductor high-current connectors are not recommended for future designs because of inadequate ground return through fifth wheel/king pin. Cable size selection is to be made by the vehicle OEM for specific applications and the specific voltage drop requirements of those applications. This SAE Standard covers two variants of high-power two-conductor connections: a heavy duty version, with horizontally aligned pins, typically for lift-gate battery charging; and a medium duty version, with vertically aligned pins, typically for loads such as power tarpaulins.Cross Reference:
