TE Connectivity 1775862-2 产品概述

一、产品简介

TE Connectivity(泰科电子)型号 1775862-2 是一款面向板对板连接的低剖面 mSATA / Mini PCI Express 母座,采用卧贴(right-angle / low-profile)SMD 封装,适用于板上安装的 mSATA/mini PCIe 模块连接。该产品为 52 针、中心线间距 0.8 mm 的高密度连接器,堆叠高度(板对板间距)为 5.2 mm,带定位柱以增强机械强度与定位精度,触点经过镀金处理以确保可靠的电气接触与耐腐蚀性。总体设计旨在满足嵌入式储存模块与 mini PCI Express 外设在有限空间内的高速互连需求。

二、关键规格

  • 接口形态:mSATA(兼容 mini PCI Express 物理接口)
  • 引脚数:52 针
  • 中心线间距(Pitch):0.8 mm
  • 堆叠/板对板高度:5.2 mm
  • 连接器类型:母(板端插座)
  • 安装方式:卧贴,SMD(表面贴装)
  • 附加特征:带柱(定位/支撑柱)
  • 触点/表面处理:镀金(闪金/金属亮面处理)
  • 封装描述:SMD, P=0.8mm, 卧贴
  • 品牌:TE Connectivity(泰科电子)

三、机械特性与安装注意

该连接器采用低剖面卧贴设计,堆叠高度 5.2 mm,非常适合对高度有严格限制的单板系统或模块化设计。带柱结构提供了可靠的定位与机械支撑,减少模块插拔或振动时的应力集中。作为 SMD 元件,推荐使用与之匹配的 PCB 封装设计(建议参考制造商所提供的推荐焊盘与 3D 模型),并在回流焊工艺中遵循合适的温度曲线以保证焊点可靠性。

设计时需关注:

  • 定位柱的过孔或沉孔尺寸与 PCB 板厚匹配,以保证机械贴合。
  • 焊盘设计与阻焊层开窗,避免焊料桥接同时确保足够焊点强度。
  • 周边走线与器件布局应为高频差分信号留出合适的阻抗控制区与参考接地平面。
  • 若在振动或冲击环境下使用,可在连接器周围增加机械支撑或胶固定措施。

四、电气特性与信号完整性

0.8 mm 的高密度间距和 52 针配置,使该连接器适用于承载 PCI Express 类的高速差分信号(mSATA 基于 mini PCIe 物理规范)。镀金触点可提供良好的接触电阻和长期可靠性,有利于维持高速传输时的信号稳定性。

在电路板设计与布线时,应注意:

  • 差分对走线的阻抗控制与配对长度一致性,以减少时序偏差与信号反射。
  • 为高速信号提供连续的地平面或参考层,必要时使用地引脚或屏蔽结构降低串扰。
  • 关注电源旁路与滤波,避免电源噪声影响高速链路。

五、典型应用场景

  • 嵌入式储存:mSATA 固态硬盘(SSD)模块在工控、网络设备与便携系统中的板上直连。
  • 无线与通信模块:与 mini PCIe 型无线、4G/5G、Wi‑Fi 或蓝牙模块配合使用的板对板连接。
  • 工业与医疗设备:需要高可靠性、高密度、低剖面的模块化设计场合。
  • 消费与嵌入式计算平台:如超薄笔记本、单板计算机、机顶盒等对空间敏感的系统。

六、设计与选型建议

  • 对兼容性:在选用该连接器时,请确认目标模块的机械尺寸与引脚定义与 mSATA / mini PCIe 规范一致,避免因规格差异导致无法插合或功能不匹配。
  • 机械强化:在有频繁插拔或强振动环境下,建议利用定位柱结合结构胶或夹具加强机械支撑。
  • 焊接工艺:采用推荐的回流焊工艺,避免过大的热应力;焊接后进行目视与 X 射线检验以确保焊点质量。
  • EMC/EMI 考量:对高速链路实施必要的屏蔽和接地策略,减少电磁干扰对系统性能的影响。
  • 可靠性测试:在量产前进行插拔耐久、温循环与振动测试,验证长期使用下的接触可靠性与机械稳定性。

七、总结

TE Connectivity 1775862-2 是一款面向 mSATA / mini PCIe 模块的高密度、低剖面 SMD 板对板母座,具有 52 针、0.8 mm 间距和 5.2 mm 堆叠高度的设计特色,带柱结构与镀金触点增强了机械与电气可靠性。它适用于空间受限且需支持高速差分信号的嵌入式与工业应用。设计时注意焊接工艺、PCB 封装与信号完整性处理,可在实际产品中获得稳定的模块互连性能。若需进一步的 PCB 封装图、3D 模型或详细机械尺寸,建议参考 TE Connectivity 的产品资料与数据手册。

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.
