WAFER-XH2.54-2PLB线对板针座产品概述

这款WAFER-XH2.54-2PLB是讯普(XUNPU)推出的小型化线对板连接器件,针对紧凑空间内的小功率信号/电源传输需求设计,凭借可靠接触、小体积布局和便捷贴装,适配消费电子、工业控制等领域的小型设备。

一、产品定位与核心应用场景

定位于低功耗小型设备的线对板连接,核心应用场景包括:

  1. 消费电子:智能台灯、蓝牙音箱、智能手环的电池连接模块;
  2. 工业控制:小型温湿度传感器、微型PLC扩展模块;
  3. 通讯终端:低功耗WiFi模块、物联网终端设备。

其2PIN紧凑设计避免了多余PIN数的浪费,精准适配多数小电流电路的连接需求。

二、关键参数与性能优势

核心参数梳理

参数项 具体规格 针座类型 线对板针座 PIN数/排数 总2P,1排×2P 间距 2.5mm(标准间距) 安装方式 立贴式SMD(表面贴装) 额定电流/电压 3A(100%负载)/250V AC/DC 触头材质/镀层 黄铜(导电基底)+ 镀锡(焊接性) 塑料材质 LCP(高温工程塑料) 工作温度范围 -25℃ ~ +85℃ 板上典型尺寸 Z轴高7.9mm,X轴长10mm,Y轴宽5.95mm 附加特征 辅助焊脚(提升焊接强度) 颜色 米色(塑料主体)

性能优势

  1. 电流承载能力:3A额定电流可满足5V/2A、12V/1.5A等多数小功率电路的电源传输;
  2. 接触可靠性:黄铜触头镀锡,既保证低接触电阻(<20mΩ),又提升抗氧化性,长期使用无接触不良;
  3. 小体积适配:板上尺寸仅7.9mm(高)×10mm(长)×5.95mm(宽),适合高密度PCB布局;
  4. 焊接稳定性:辅助焊脚增加焊接点数量,抗拉力>5N,可有效防止针座脱落。

三、结构设计与工艺特点

结构细节

  1. 插针布局:1排2PIN直线排列,间距2.5mm,与XH系列端子完全兼容,线端可直接匹配XH-2P端子;
  2. 立贴设计:针座垂直于PCB板安装,节省水平空间,适配薄型设备(如智能手表、小型模块);
  3. 辅助焊脚:针座两侧增加2个辅助焊脚,焊接时与主插针同步贴装,显著提升抗振动性能;
  4. 塑料主体:采用LCP高温塑料,可承受回流焊温度(260℃±5℃),无变形、开裂风险。

工艺优势

  • 触头采用精密冲压工艺,尺寸公差±0.05mm,保证插针与端子的配合精度;
  • 镀锡层厚度≥3μm,符合RoHS环保标准,适配欧盟市场需求;
  • 塑料主体注塑成型,表面光滑无毛刺,提升装配效率。

四、安装与兼容性说明

安装要求

  1. 贴装方式:采用SMT自动化贴装,需配合回流焊工艺(温度曲线符合LCP塑料耐温要求);
  2. 焊接注意:辅助焊脚需与主插针同时焊接,避免仅焊主插针导致强度不足;
  3. PCB布局:预留对应SMD焊盘(间距2.5mm),主焊盘建议1.2mm×1.8mm,辅助焊盘0.8mm×1.0mm。

兼容性

  • 完全兼容XH系列线端端子(如XH-2P端子),线径适配0.5~1.0mm²导线;
  • 可与同系列2PIN立贴针座互换,无需更改PCB设计;
  • 适配主流SMT贴片机(富士、西门子等),生产效率≥1000pcs/小时。

五、可靠性与环境适应性

可靠性测试

  • 接触电阻测试:1000次插拔后,接触电阻≤50mΩ(无明显上升);
  • 抗振动测试:符合IEC 60068-2-6标准(振动频率10~2000Hz,加速度2g),无接触不良;
  • 耐温测试:-25℃存储72小时、+85℃存储168小时,性能无衰减。

环境适应性

  • 工作温度覆盖多数场景(室内电子、工业低温环境);
  • LCP塑料耐弱酸碱,可耐受酒精等清洁液擦拭;
  • 镀锡触头抗氧化,长期使用无氧化层,信号传输稳定。

六、选型与注意事项

选型要点

  • 确认需求:需2PIN、1排、立贴、2.5mm间距时优先选择本型号;
  • 配套确认:线端需匹配XH系列2P端子,避免端子不兼容;
  • 环境确认:若温度超85℃或低于-25℃,需更换耐温更高型号。

注意事项

  1. 存储:常温干燥环境(15~35℃,湿度≤60%),避免潮湿影响镀锡层;
  2. 焊接:禁止手工烙铁直接焊接(防塑料变形),需用回流焊;
  3. 负载:严禁超过3A额定电流(否则触头过热、塑料软化);
  4. 插拔:建议≤500次(超次易导致触头磨损)。

这款WAFER-XH2.54-2PLB针座凭借紧凑设计、可靠性能和便捷安装,成为小型电子设备线对板连接的高性价比选择,广泛应用于量产场景。

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
