CONSTRUCTION结构解析
Connection structure and design details连接结构与设计要点
Use the an-prc-152 usb & power module pigtail form as a starting point and confirm these design points against drawings and the actual equipment.以AN-PRC-152接口 · USB与电源模块尾线束的结构形式为起点，结合图纸和实际设备确认以下设计要点。
Pigtail connection form尾线连接形式
A lead section extends behind the connector, allowing length, further termination and support to follow the equipment connection.插接端后保留引线段，便于按设备接线位置确定长度、后续端接与支撑。
Trunk and branch layout主干与分支
Locate trunk and branch datums from equipment fixing points. Allow room for mating, bends and servicing so branches do not transfer installation loads to contacts.以设备固定点确定主干和各支路的尺寸基准，预留插拔、弯曲和维护空间，避免支路把拉力传递到端子。
Signal path信号路径
Define signal type, pair allocation, shield continuity and termination as well as the connector shape. Establish transmission performance from the actual cable, length and system validation.在接口外形之外确认信号类型、线对分配、屏蔽连续性和端接方法；传输能力应按实际线材、长度及整机验证结果确定。
Interface and function review接口与功能确认
External molded geometry alone does not establish sealing外部模制结构不能单独证明防水

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. Define boot length, profile, exit angle and nearby fixing points.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，定义尾套长度、外形、出线角度和附近固定点。
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 hardness and bonding for the jacket material and intended bending duty.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，按护套材料与目标弯曲条件选硬度和粘接方式。
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. Insert support, parting lines and molding conditions should protect internal terminations.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，嵌件支撑、分型位置和成型条件应保护内部端接。
Equipment panels and circular interfaces设备面板与圆形接口
Start with the cutout, panel thickness, mounting direction and rear clearance. Coordinate contact arrangement and cable exit with the complete assembly view. Verify bending, pull force and fixing retention in the installed configuration.面板连接以开孔、板厚、装配方向和后方净空为起点；接点排列与电缆出口还需要对应完整总装视图。选配时，按完整安装状态验证弯折、拉力与固定保持。
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. Define boot length, profile, exit angle and nearby fixing points.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，定义尾套长度、外形、出线角度和附近固定点。
Enclosure entries and cable retention机箱穿线与入口固定
Match cable entries to actual diameter, panel thickness and fixing method. Keep jacket retention independent of the internal termination. Select hardness and bonding for the jacket material and intended bending duty.线缆入口需匹配实际外径、板厚和固定方式；护套夹持与内部端接之间应保留独立的支撑路径。选配时，按护套材料与目标弯曲条件选硬度和粘接方式。
