TE Connectivity 5-747905-2 产品概述

一、产品简介

TE Connectivity 型号 5-747905-2 为一款用于电缆端的 D-Sub 母头(9Pin),采用焊线式(soldering / solder cup)连接方式,双排排列(2 rows),外壳为黑色,标称为 HD(High Density)系列结构。该产品由美国泰科(TE Connectivity)生产,面向工业通信、测试测量及各类设备的串行接口与信号传输场景设计。

二、主要特性

  • 引脚数:9P(9 针),双排布局,适配常见 DB9 接口标准。
  • 极性:母(female),用于电缆端组装,与公头(male)配合使用。
  • 安装方式:焊线式(solder cup),便于直接焊接线缆导线或以端子线连接。
  • 额定电流:信号脚额定电流 3A,适合低电流信号与控制信号传输。
  • 工作温度范围:-55℃ 至 +105℃,满足严苛环境下的稳定工作要求。
  • 颜色与外观:黑色外壳,耐用外观适配多数工业设备面板与线缆护套。
  • 结构:兼顾机械强度及电气性能的 D-Sub 架构,常见用于高可靠性连接场合。

三、典型应用场景

  • 工业控制与自动化设备的串行通信接口(如 RS‑232/RS‑422/RS‑485 等低压信号)。
  • 测试与测量设备的外部接口,如示波器、数据采集仪、校准仪器等。
  • 仪器仪表、嵌入式系统与旧系统改造中常见的 DB9 接口替换或线缆终端。
  • 医疗、交通、安防等领域需要可靠信号连接的应用场合。

四、关键技术参数(摘要)

  • 品牌:TE Connectivity(美国泰科)
  • 型号:5-747905-2
  • 接口类型:D-Sub 母头,9 Pin,高密度(HD)结构
  • 连接方式:焊线式(solder cup)用于电缆端组装
  • 排数:2 排
  • 额定电流(信号脚):3A/脚
  • 工作温度:-55℃ ~ +105℃
  • 颜色:黑色
  • 其它:适配标准 D‑Sub 螺丝固定方式以实现可靠机械锁定与屏蔽接地

五、安装与焊接注意事项

  • 线缆准备:建议使用合适截面积的导线以匹配 3A 额定电流,必要时采用屏蔽线以降低干扰。
  • 焊接工艺:采用适当温度与时间控制的手工或波峰焊/回流前处理(根据线材与焊杯结构),避免过高温度导致绝缘材料或外壳变形。
  • 应力缓解:焊后应配合使用应力缓解措施(如热缩管、缠绕胶带或夹具)防止外拉力传递到焊点。
  • 屏蔽与接地:若需屏蔽效果,确保金属外壳与设备机壳或屏蔽层可靠接地;连接螺柱/固定件需紧固到位。
  • 清洁与防腐:焊后清除残留助焊剂,必要时采用防腐处理或涂覆以延长寿命(注意涂覆材料的温度与化学相容性)。
  • 环境适配:在极端温度或湿度环境下使用前,请确认所用线缆与密封措施满足环境要求。

六、兼容性与选型建议

  • 与标准 DB9 公头兼容,可替代常规 RS‑232/串口用途的母端连接器。
  • 选型时确认是否真正需要 HD(高密度)外壳及焊线式终端;若需快速现场装配可考虑带应力释放套或带后壳的整套组件。
  • 如需更高电流或电源级别传输,请选择额定电流更高的接插件或使用多脚并联并遵循制造商电气限制。
  • 若要求电磁兼容(EMC)、防水或更高机械保护等级,请核对 TE 提供的具体系列或选择带密封/防护等级更高的型号。

七、总结

TE Connectivity 5-747905-2 是一款面向电缆端、焊线式的 D‑Sub 9 针母插头,具备工业级的温度范围与 3A 的信号电流能力,适用于需可靠串行/信号连接的各类设备与系统。在选型与安装时建议注意焊接工艺、应力缓解与屏蔽接地等细节,以确保长期稳定与信号完整性。如需进一步的机械图纸、引脚排列或环境测试数据,请参考 TE 官方资料或联系授权经销商获取数据表与装配指南。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
