APPLICATIONS连接的应用
Application directions应用方向
These are connection directions for project discussion. Suitability depends on interfaces, circuits, installation conditions and project validation; configuration can be adapted to the equipment.以下为可讨论的连接方向。实际适用性取决于接口、电路、安装环境和项目验证，可按设备需求调整。
Routing boundaries around hot equipment热区设备的布线边界
Separate continuous temperature, peaks and exposure time around hot equipment. Review wire, terminals and protective parts against their own limits. Record molding conditions and service-temperature evidence for the actual material grade.热区布线需要区分连续温度、峰值和暴露时间，线材、端子及保护件应按各自限制评审。选配时，按实际材料牌号记录成型条件和使用温度依据。
Terminal wiring inside control cabinets控制柜内的端子配线
Coordinate terminal positions, duct exits and service access within the cabinet. Wire labels should correspond to the circuit table and equipment ports. Check temperature limits for the internal cable, contacts and components individually.柜内连接需协调端子位置、线槽出口和可维护空间，线号应能对应回路表与设备端口。选配时，内部线缆、端子与器件逐项核对温度边界。
Internal machine connections and service设备机内连接与维护
Keep internal connections clear of working zones and moving parts. Allow appropriate cable length between supports, interfaces and service paths. Define molding temperature, pressure, time and insert-protection methods.设备机内连接要避开加工区与运动部件，并在固定点、接口和检修路径之间保留合理线缆余量。选配时，定义成型温度、压力、时间及嵌件保护方法。
Contact and fine-wire termination端子与细线端接
Contact selection depends on conductor construction, insulation diameter and tooling limits. Set wire preparation and crimp inspection for the actual contact part. Agree bonding and mechanical checks after thermal aging and cycling.端子选择同时取决于导体结构、绝缘外径和工具范围；备线尺寸与压接检查应落到实际接点型号。选配时，约定热老化、热循环后的粘接和机械检验。
Cable exits and nearby support电缆出口与近端支撑
Keep bending loads away from contacts through appropriate rear support. Review exit angle, retention distance and boot dimensions with the enclosure. Record molding conditions and service-temperature evidence for the actual material grade.端头后方的支撑要避免把弯折载荷直接传到接点，出线角度、固定距离和尾套尺寸需与机壳一起评审。选配时，按实际材料牌号记录成型条件和使用温度依据。
