CONSTRUCTION结构解析
Connection structure and design details连接结构与设计要点
Use the 4-position circular socket pigtail form as a starting point and confirm these design points against drawings and the actual equipment.以四位圆形插座尾线的结构形式为起点，结合图纸和实际设备确认以下设计要点。
Plug-in connection end插接式端头
The end uses a plug-in form, with clearance arranged for insertion, removal and cable bends.端头采用插接形式，可围绕安装位置安排插入、退出及线缆弯曲空间。
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。

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Can circular connectors with the same diameter be interchanged?圆形连接器外径相同就可以互换吗？
No. Family, keying, contact arrangement, shell fit, coupling, contacts and seals can differ. Compatibility requires complete interface data and mating verification.不可以。系列、键位、针芯排列、壳体配合、锁紧结构、触点和密封都可能不同，必须依据完整接口资料与对插验证确认。
Does a metal circular connector automatically provide shielding?金属圆形连接器一定有屏蔽吗？
No. Shielding depends on cable shield termination, backshell, shell continuity, panel connection and system grounding. A metal appearance alone proves nothing.不一定。有效屏蔽取决于电缆屏蔽端接、尾壳、壳体连续、面板连接与系统接地，金属外观本身不能证明屏蔽性能。
Are all circular connector assemblies waterproof?圆形连接器组件都能防水吗？
No. Protection depends on the complete mated interface, seals, cavity plugs, backshell, cable diameter, mounting orientation and the defined test configuration.不能。防护取决于完整插合接口、密封圈、堵孔件、尾壳、线缆外径、安装方向与规定测试配置。
