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。
External interfaces on portable equipment便携设备的外部接口
Consider handling, plug grip and cable bends together. Align the exit direction with the device position during use. Record retracted length, normal working extension and coil diameter separately.便携设备连接要同时考虑操作手势、插头握持和尾部弯曲空间，线缆出口方向应与实际使用姿态协调。选配时，分别记录收缩长度、正常工作伸长和圈径。
Routing and retention on moving equipment移动设备的走线与固定
Define travel, speed and retention at both ends of moving connections. Set separate targets and validation conditions for bending and torsion. Define coil direction, straight-tail lengths and both cable exits.移动连接需明确动作行程、速度和两端固定，动态弯曲与扭转应分别设定目标和验证条件。选配时，确定螺旋方向、直尾长度及两端出线方向。
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. Select conductor and jacket construction for restoring force and operating duty together.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，导体与护套结构按回复力和工况共同选择。
Module wiring within enclosures机箱内部的模块配线
Coordinate board positions, module removal and wire bends within the enclosure. Preserve insulation clearance and support behind each termination. Specify extension frequency, cycle target and fixing conditions at both ends.机箱内部配线需要协调板卡位置、模块拆装和导线转弯空间；端接后的绝缘与支撑不能被外壳挤压。选配时，注明伸缩频率、循环目标和两端固定条件。
Detachable circular connections可拆卸圆形连接
Check gender, keying, coupling and end-face views together. Equal contact counts do not replace confirmation of the exact series and part numbers. Record retracted length, normal working extension and coil diameter separately.圆形接口需要同时核对公母、键位、锁紧方式和端视图，针数相同并不能替代完整系列与料号确认。选配时，分别记录收缩长度、正常工作伸长和圈径。
