DF40C-40DS-0.4V(51) 产品概述

DF40C-40DS-0.4V(51)是日本广濑电机(HRS)推出的0.4mm间距高密度板对板连接器,专为紧凑型电子设备的内部信号与小功率传输设计,凭借双排40针垂直立贴结构、金镀层触头及宽温适应性,在有限空间内实现稳定可靠的电气连接,是消费电子、工业控制等领域的优选方案。

一、基本参数与型号解析

1. 型号含义拆解

  • DF40C:广濑DF40C系列标识(0.4mm间距板对板连接器家族);
  • 40:总引脚数(双排各20针,共40P);
  • DS:设计代码(代表槽型对接结构);
  • 0.4:引脚中心距(相邻触头间距0.4mm);
  • V:安装方式(Vertical,垂直立贴);
  • 51:镀层代码(对应0.2~0.3μm厚金镀层)。

2. 核心参数清单

参数类别 具体参数 引脚总数 40P(双排2×20) 引脚间距 0.4mm 安装方式 表面贴装(立贴/垂直SMT) 连接结构 槽型板对板对接 触头镀层 纯金(Au) 额定电流 300mA/触头(持续) 工作温度范围 -35℃ ~ +85℃ 插拨寿命 ≥500次 封装尺寸 约10mm×2.5mm×5mm

二、核心设计特点

1. 超小间距高密度集成

0.4mm引脚间距大幅压缩连接器体积,双排40针设计仅占用约10mm×2.5mm的PCB面积,满足智能手机、智能穿戴等对空间极致压缩的设备需求,是小型化产品的核心连接组件。

2. 垂直立贴节省空间

垂直立贴安装方式使连接器垂直于PCB表面,相比卧式贴装减少30%以上横向占用空间,尤其适合多层PCB堆叠、模块紧凑布局的场景(如TWS耳机充电盒内部)。

3. 槽型对接提升可靠性

采用嵌入式槽型对接结构,插头与插座触头精准配合,避免插拨时横向偏移,降低触头磨损风险;同时槽型设计具备防误插功能(方向对准后才能插入),减少生产失误。

4. 金镀层触头性能稳定

触头表面镀0.2~0.3μm厚纯金,具有:

  • 低接触电阻(典型值<20mΩ),减少信号衰减;
  • 耐氧化、耐磨损,适应频繁插拨;
  • 抗腐蚀,提升潮湿/弱腐蚀环境下的寿命。

5. 宽温区环境适应性

工作温度覆盖-35℃至+85℃,满足工业控制(如低温车间)、车载电子(如高温座舱)等场景的温度变化需求,无需额外防护即可稳定运行。

三、典型应用场景

1. 消费电子领域

  • 智能穿戴:智能手环/手表的主板与心率传感器、蓝牙模块的连接;
  • 便携音频:TWS耳机充电盒内部PCB与电池、充电模块的信号传输;
  • 小型游戏机:游戏手柄内部PCB与按键板、摇杆的板对板连接。

2. 工业控制与物联网

  • 微型PLC:输入输出模块与主控制板的板对板连接;
  • 传感器节点:工业物联网(IIoT)中温度/压力传感器与信号处理板的传输。

3. 汽车电子

  • 车载信息娱乐:中控屏内部PCB与触控模块、显示驱动板的连接;
  • 车身控制器:车门控制模块、座椅调节模块的内部电路连接。

4. 医疗设备

  • 小型诊断仪器:血糖监测仪、血氧仪的主板与显示模块、电池的连接。

四、性能优势与可靠性

1. 电气性能稳定

单触头300mA额定电流满足大多数小功率信号(如SPI、I2C)与电源传输需求,金镀层触头的低电阻特性可支持高速数字信号传输(如100Mbps以上)。

2. 机械可靠性

  • 槽型对接结构抗震性好,符合IEC 60068-2-6振动测试标准(10~2000Hz,1.5g加速度);
  • 插拨寿命≥500次,满足设备生产、维护过程中的多次插拨需求。

3. 生产适配性

SMD封装适合自动化贴装(回流焊工艺),可与其他SMD元件同步生产,贴装精度要求为±0.1mm,与主流贴片机兼容,提升工厂生产效率。

4. 兼容性

与HRS DF40C系列同规格插头(如DF40C-40P-0.4V)完全兼容,对接精度高,避免因连接器不匹配导致的连接故障。

五、安装与使用注意事项

1. 贴装工艺要求

  • 回流焊温度曲线:峰值温度建议245±5℃,每个引脚焊接时间不超过10秒(避免高温损坏金镀层);
  • 焊盘设计:PCB焊盘需与引脚尺寸匹配(约0.5mm×0.3mm),确保焊接牢固。

2. 插拨操作规范

  • 插拨时需垂直对准槽型结构,避免斜插导致触头弯曲;
  • 插拨力控制在5~10N范围内,超出范围可能缩短触头寿命。

3. 存储与维护

  • 存储环境:常温干燥(1535℃,4060%RH),避免长期暴露在高湿度或腐蚀性气体中;
  • 清洁方式:触头污渍可用无水乙醇轻轻擦拭,禁止用尖锐工具刮擦镀层。

4. 电流使用限制

  • 单触头持续电流不超过300mA,多触头并联时需按数量折算总电流(如2个触头并联支持600mA),避免过载发热。

总结:DF40C-40DS-0.4V(51)凭借高密度、小尺寸、高可靠性的特点,成为紧凑型电子设备内部连接的核心组件,尤其适合对空间与性能平衡要求较高的消费电子、工业控制等领域。

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.
