AGV/AMR是"线束密度最高的移动设备之一"：车体里挤着电池、驱动器、升降机构、雷达、调度无线模块，振动+频繁启停+空间狭小，对线束的考验比固定设备严苛得多。
AGVs and AMRs pack battery, drives, lifters, LiDAR and wireless modules into a vibrating, space-starved chassis — far harsher on harnesses than fixed equipment.
1. 电池到驱动器：短而粗的主回路1. Battery to drive: short and thick
主放电回路电流大（几十安培），线径按持续电流选（如12AWG对应约60A场景再降额），长度尽量短、成对布线减小环路面积；必须加屏蔽时优先处理这一段——它是全车最大干扰源。
Size main discharge runs by continuous current, keep them short and paired to shrink loop area; shield this segment first — it is the biggest noise source on board.
2. 升降/顶升机构：高柔性是硬要求2. Lifting mechanisms: high-flex is mandatory
顶升模组每次搬运都弯折线束，普通PVC线几万次就断。选高柔性结构（多股细铜丝+铜箔丝），配合走线留"应力释放弯"（服务环），并在治具上做弯折寿命验证。拖链场合用专用拖链电缆，注意最小弯曲半径。
Lift modules flex the harness every cycle; ordinary PVC fails after tens of thousands. Use high-flex wire with service loops, verify flex life on fixtures, and use chain-rated cable in cable chains.
3. 充电系统：极性与触点保护3. Charging: polarity and contact protection
自动充电对接触式充电极/充电刷块，线束要有防反接设计与足够的载流余量；充电回路保险丝位置要便于维护。XT60类连接器在AGV充电口很常见，注意插拔寿命。
Contact-charging systems need reverse-polarity protection and current margin, with accessible fuses. XT60-class connectors are common at AGV charge ports — mind cycle life.
4. 信号线：远离动力线，双绞+屏蔽4. Signal lines: route away, twist, shield
雷达（LiDAR）、IMU、编码器信号对干扰敏感，与动力线分槽或保持至少50mm间距，差分信号双绞并屏蔽接地。调度天线位置要避开金属遮挡与干扰源。
Keep LiDAR/IMU/encoder signals at least 50mm from power runs, twist differential pairs, shield and ground them. Mount antennas clear of metal and noise.
5. 维护性设计5. Design for service
模块化接插（驱动器/雷达可整件快换）、线束标签编码与图纸一致、关键节点可触及。AGV是7×24运行设备，"可维护性"就是"可用性"。
Modular connectors for quick swaps, labels matching drawings, accessible nodes. AGVs run 24/7 — serviceability is availability.
