WAFER-XH2.54-4PWB 线对板针座产品概述

WAFER-XH2.54-4PWB是讯普(XUNPU)推出的一款单排4Pin卧贴式线对板针座,属于其经典XH系列连接器产品,专为电路中导线与PCB板的稳定连接设计,兼顾紧凑尺寸、可靠性能与便捷安装,适配消费电子、工业控制等多领域的低功率信号/电力传输需求。

一、产品基本定位与品牌背景

作为讯普在小间距连接器领域的成熟产品,WAFER-XH2.54-4PWB针对小型化设备内部连接需求优化设计,既延续了XH系列“高适配性、低成本”的特点,又通过卧贴SMD结构与辅助焊脚提升了焊接可靠性。讯普作为专业电子连接器制造商,在端子、针座的材料选型与结构设计上积累了多年经验,确保产品在量产稳定性与性能一致性上满足市场需求。

二、核心参数全面解析

该产品的关键参数覆盖结构、电气、材料、尺寸四大维度,具体如下:

  • 结构参数:单排4Pin(1x4P)设计,针间距2.5mm,符合XH系列标准规格,排数1、每排4针,总PIN数4,附加辅助焊脚增强焊接强度;
  • 电气参数:额定电流3A(满足多数小功率设备电力传输),额定电压250V(AC/DC通用),触头采用黄铜材质+锡镀层,低电阻且抗氧化;
  • 材料参数:塑料壳体为LCP(液晶聚合物),耐温范围-25℃~+85℃,抗冲击、抗老化,适合长期稳定使用;
  • 尺寸参数:Z轴(板上高度)6.2mm,X轴(板上边线长度)15mm,Y轴(板上宽度)7.8mm,紧凑设计适配高密度PCB布局;
  • 安装方式:卧贴SMD(表面贴装),兼容自动化贴装线,提升生产效率。

三、关键特性与性能优势

  1. 电气连接稳定可靠
    黄铜触头的低电阻特性确保信号/电力传输损耗小,锡镀层有效防止触头氧化,长期使用不出现接触不良;额定3A电流可覆盖小型家电、传感器等设备的常规功率需求。

  2. 结构强度与焊接可靠性
    新增的辅助焊脚能分散焊接应力,避免因振动、拉扯导致的焊脚脱落;LCP塑料壳体耐温抗冲击,即使在-25℃低温或85℃高温下也不会变形,适配复杂环境。

  3. 安装适配便捷高效
    卧贴SMD结构无需钻孔,可直接通过自动化贴装线焊接,降低人工成本;紧凑尺寸(15mm×7.8mm×6.2mm)适合小型化设备的PCB布局,提升设备集成度。

  4. 环境适应性强
    工作温度范围宽(-25℃~+85℃),可满足室内外常温场景(如家庭、办公室、小型车间)的使用需求;米色壳体的外观设计与多数PCB板配色协调,便于识别。

四、典型应用场景

WAFER-XH2.54-4PWB因尺寸紧凑、性能稳定,广泛应用于以下领域:

  • 消费电子:小型家电(加湿器、台灯、智能插座)、便携式设备(充电宝、蓝牙音箱、智能手环)的内部导线与PCB连接;
  • 工业控制:小型传感器(温度、湿度传感器)、PLC模块、微型控制器的信号传输连接;
  • 通信设备:小型路由器、交换机、无线AP的内部组件连接,适配设备小型化趋势;
  • 汽车电子(低压场景):车载小功率附件(氛围灯、点烟器扩展、行车记录仪接线)的低压连接(需注意额定电压匹配)。

五、安装与使用注意事项

为确保产品性能稳定,需注意以下几点:

  1. 贴装工艺匹配:卧贴需采用SMD回流焊工艺,焊盘尺寸需与针脚(含辅助焊脚)匹配,避免虚焊或假焊;
  2. 线缆适配要求:需搭配XH系列对应端子的导线(2.5mm间距端子线),插合时需确保端子与针座完全咬合,防止接触不良;
  3. 环境防护:避免长期暴露在高温(>85℃)、高湿或腐蚀性气体环境中,若需户外使用需额外增加防护措施;
  4. 焊接温度控制:回流焊温度建议控制在260℃以内(峰值不超过265℃),避免过温导致塑料壳体变形。

综上,WAFER-XH2.54-4PWB是一款高性价比、高可靠性的小间距线对板针座,兼顾紧凑尺寸与稳定性能,适配多领域低功率连接需求,是小型电子设备内部连接的优选方案。

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
