DF61-2P-2.2V(23) 线对板针座产品概述

DF61-2P-2.2V(23)是日本广濑电机(HRS)推出的一款小间距线对板表贴针座,针对紧凑空间内的可靠连接需求设计,广泛适用于消费电子、工业控制、汽车电子等领域。以下从核心定位、参数特性、设计优势、应用场景及选型注意事项展开概述。

一、产品核心身份与定位

该产品属于HRS DF61系列线对板连接器的2P(2触头)型号,聚焦2.2mm小间距高密度连接场景,主打“低成本、高可靠、易量产”的表贴解决方案。其定位为中低端应用中的高性价比选择,既满足常规电子设备的电气性能需求,又能适应宽温环境下的长期稳定运行。

二、关键参数与物理特性

产品的核心参数直接决定了其适用范围,具体如下:

  1. 间距与布局:2.2mm触头间距,比传统2.54mm间距缩小13%,有效节省PCB水平空间;单排(1排)触头设计,结构紧凑。
  2. 安装与封装:采用立贴式SMD表贴封装,引脚为表贴焊盘,兼容自动化贴装设备;同时支持部分场景下的卧贴布局(需根据PCB设计调整)。
  3. 触头性能:触头基材为黄铜(导电率稳定,机械强度适中),表面镀层为锡(焊接性优异,无铅环保,成本可控)。
  4. 环境适应性:工作温度范围为**-55℃+105℃**,满足工业级(-40+85℃)及汽车级(-40~+125℃部分场景)的宽温要求;触头镀层耐腐蚀性良好,适合常规湿度环境。
  5. 基本规格:触头数量2P,排数1,符合RoHS环保标准。

三、设计特点与应用优势

DF61-2P-2.2V(23)的设计针对紧凑场景痛点,具备以下核心优势:

  1. 高密度布局适配:2.2mm小间距可在相同PCB面积内增加触头数量,适合便携式设备(如智能手环、蓝牙耳机)的内部子板连接,有效缩小整机体积。
  2. 可靠连接保障:黄铜触头的低接触电阻(<20mΩ)确保信号传输稳定;锡镀层与PCB焊盘的焊接强度高,无铅焊接工艺兼容现有生产线,减少生产缺陷。
  3. 安装灵活度:立贴设计可垂直于PCB表面,节省水平空间;若需水平布线,部分型号支持卧贴转换(需确认HRS官方适配性),适配不同PCB布局需求。
  4. 宽温环境兼容:-55~+105℃的工作温度覆盖了大多数工业控制(如PLC模块)、车载小功率模块(如中控传感器接口)的使用场景,无需额外散热或防护。

四、典型应用场景

该产品因参数匹配性强,在多个领域有成熟应用:

  1. 消费电子:便携式设备(智能手表充电座、TWS耳机充电盒)、小型家电(智能音箱、遥控器)的内部线对板连接,满足紧凑设计需求。
  2. 工业控制:小型PLC模块、传感器节点(温度/湿度传感器)、电机驱动板的辅助连接,适应车间环境的宽温变化。
  3. 汽车电子:车载中控面板的按键模块、车门传感器接口的低功率连接(需确认汽车级认证,部分场景需搭配HRS汽车级连接器)。
  4. 通信设备:小型路由器、交换机的子板(如WiFi模块、电源模块)连接,支持高密度布局。

五、选型与使用注意事项

为确保产品可靠运行,需注意以下要点:

  1. 型号匹配:DF61系列中,“V”代表立贴(Vertical),“H”代表卧贴(Horizontal),需根据PCB布局选择对应型号;触头数量需与线端连接器(如DF61-2P-2.2C线端)一致,避免 mismatch。
  2. 焊接工艺:锡镀层焊接温度建议控制在260℃以下(峰值温度),焊接时间不超过3秒,避免过热导致触头镀层脱落或针座变形。
  3. 环境防护:若使用场景湿度超过85%RH,需对针座进行灌封或涂覆防护,防止触头氧化。
  4. 批量生产:SMD封装可通过自动化贴片机贴装,贴装精度需控制在±0.1mm以内,确保引脚与焊盘对齐。

六、总结

DF61-2P-2.2V(23)作为HRS DF61系列的核心型号,凭借小间距高密度、宽温可靠、易量产的特点,成为紧凑电子设备中高性价比的线对板连接解决方案。其适配多领域应用场景,是消费电子、工业控制等行业设计师的常用选择。

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.
