DF40HC(3.5)-40DS-0.4V(51) 连接器产品概述

一、产品基本身份与系列定位

该连接器由HRS(广濑电机) 研发生产,属于DF40HC高密度小型化连接器系列。型号中各代码含义明确:

  • (3.5):连接器整体 pitch(引脚中心距)为3.5mm;
  • 40DS:双排布局,共40个触头(DS为Double Side缩写);
  • 0.4V:触头间间距0.4mm;
  • (51):关联金镀层工艺与包装规格。

产品核心定位为小空间内多信号传输,兼顾密度、可靠性与生产适配性,适用于工业、车载、医疗等对尺寸与性能要求严格的场景。

二、核心参数明细

2.1 电气参数

  • 触头镀层:金(典型厚度≥0.2μm),抗氧化、低接触电阻;
  • 额定电流:单触头0.5A(AC/DC);
  • 额定电压:50V(AC/DC);
  • 接触电阻:初始值≤20mΩ,插拔后≤50mΩ;
  • 绝缘电阻:≥100MΩ(500V DC)。

2.2 物理与结构参数

  • PIN总数:40个(双排均匀分布);
  • 触头间距:0.4mm;
  • 安装方式:立贴式SMD(表面贴装,垂直于PCB);
  • 连接结构:槽型对接(精准定位,防错位);
  • 安装高度:≤5mm(小型化设计,适配紧凑空间);
  • 插拔方向:垂直对接(节省水平空间)。

三、设计特性与应用优势

3.1 高密度小型化

0.4mm触头间距+3.5mm pitch的双排布局,比传统单排连接器节省约30%水平空间,在有限体积内实现40PIN信号传输,完美适配便携式设备、小型模块的内部板间连接。

3.2 可靠对接与接触性能

  • 槽型接口:对接时触头精准嵌入槽位,避免倾斜/错位导致的PIN弯曲,插拔一致性提升30%以上;
  • 双触点结构:部分型号采用双触点设计,增加接触面积,振动环境下接触电阻波动≤10mΩ;
  • 金镀层优势:耐磨损(插拔寿命≥500次),抗氧化能力强,长期使用后仍保持低接触电阻,适合高频信号传输。

3.3 生产适配性

立贴SMD封装支持自动化贴装,符合SMT生产线要求,减少手工焊接误差;卷带包装(标准包装)适配贴片机供料,便于批量生产。

四、典型应用场景

该产品因小体积、高PIN数、高可靠性,广泛应用于以下领域:

  1. 工业控制:小型PLC、传感器模块、IO接口板的内部板间连接(耐振动、抗干扰);
  2. 车载电子:车载信息娱乐系统、ADAS模块(摄像头/雷达)的小型化连接(满足车载温湿度与振动要求);
  3. 通信设备:小型基站、路由器、交换机的内部信号传输(多PIN数支持多通道信号);
  4. 医疗设备:便携式监护仪、血糖仪的内部模块连接(符合医疗设备安全标准);
  5. 消费电子:高端笔记本电脑、智能家居控制器的内部板间对接(适配轻薄设计)。

五、安装与可靠性注意事项

5.1 安装要点

  • 回流焊参数:遵循HRS推荐曲线(峰值温度240-245℃,时间≤10秒),避免过度加热损坏触头;
  • 对接操作:垂直对准槽型接口,均匀施力,禁止倾斜插拔;
  • 存储要求:未使用产品存放在干燥环境(湿度≤60%),避免镀层氧化。

5.2 可靠性验证

  • 环境适应性:工作温度-40℃+85℃,存储温度-55℃+125℃;
  • 振动/冲击:符合IEC 60068-2-6(10-2000Hz,98m/s²)、IEC 60068-2-27(1000m/s²)标准;
  • 插拔寿命:≥500次(插拔后电气性能仍符合参数要求)。

该产品凭借高密度、高可靠性与生产适配性,成为小空间多信号传输场景的优选连接器。

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
