PM254V-11-03-H85排母产品概述

PM254V-11-03-H85是国内连接器品牌XFCN(兴飞) 推出的一款单排直插式排母,专为小间距、低至中功率电子电路的稳定连接设计。该产品采用2.54mm国际标准间距,1×3P引脚配置,凭借紧凑结构、可靠电气性能及宽温适应性,成为各类小型电子设备的常用连接方案。

一、产品定位与品牌背景

XFCN(兴飞)是国内专注连接器研发、生产的厂商,核心产品线覆盖排针排母、接插件等基础连接器件,以“高性价比+稳定可靠性”为核心竞争力。PM254V系列是其经典排母产品线,PM254V-11-03-H85作为该系列下的3P单排直插型号,针对空间紧凑、电流需求适中的电子设备场景优化设计,可快速匹配同间距排针实现电路连接。

二、核心技术参数

2.1 电气性能参数

  • 额定电流:3A(满足低至中功率电路的电流传输需求,无明显发热);
  • 工作温度范围:-40℃至+105℃(覆盖户外、工业、车载等高低温环境);
  • 触头材质:黄铜(导电率优异,抗氧化性较好,保证长期连接稳定);

2.2 结构设计参数

  • 引脚配置:单排1×3P(3个独立插孔,适配3线电路连接);
  • 中心间距:2.54mm(国际通用间距,与多数插件排针兼容,互换性强);
  • 插孔类型:方孔(非传统圆孔,接触面积更大,防错位);
  • 安装方式:直插式(插件封装,PCB焊盘焊接固定,安装便捷);
  • 塑壳高度:8.5mm(紧凑设计,节省PCB板垂直空间);
  • 插孔方向:顶部插拔(操作空间充足,便于排线/排针插拔)。

三、结构设计特点

3.1 标准间距与兼容性

2.54mm是电子连接器领域的通用间距,PM254V-11-03-H85可与同间距的直插排针完美匹配,无需额外适配设计,降低电路开发成本。

3.2 方孔触头的优势

相比传统圆孔,方孔设计有两大核心优势:

  • 接触面积提升:增大与排针的接触面积,减少接触电阻(≤10mΩ),避免电流损耗;
  • 防错位性能:方孔边角定位更精准,插拔时不易出现倾斜错位,长期使用后仍能保持稳定连接,降低接触不良风险。

3.3 紧凑塑高与空间优化

8.5mm的塑壳高度是该型号的针对性优化——在保证电气性能的前提下,最大程度压缩了产品体积,适配小型化设备(如便携充电宝、智能遥控器)的PCB板空间需求,避免占用过多垂直布局。

3.4 直插安装的便捷性

直插式安装无需复杂工装,只需将引脚插入PCB焊盘后进行回流焊或手工焊接即可:

  • 焊接效率高,适合批量生产;
  • 焊接后固定牢固,不易出现虚焊、脱焊问题。

四、典型应用场景

PM254V-11-03-H85凭借小巧体积、可靠性能及宽温适应性,广泛应用于以下领域:

  1. 小型家电控制板:智能遥控器、小型加湿器、台灯等设备的电路连接;
  2. 工业低功率模块:传感器信号采集板、小型继电器控制板等(适应工业环境温度变化);
  3. 消费电子便携设备:便携式充电宝、蓝牙耳机充电盒的内部信号/电源连接;
  4. 通讯终端辅助电路:路由器、交换机的辅助控制板(与同间距排针配合传输信号)。

五、质量与可靠性保障

XFCN对该型号的质量控制严格,核心保障点包括:

  • 触头工艺:黄铜触头经表面镀锡处理(提升抗氧化性),避免长期使用后锈蚀;
  • 塑壳材料:采用耐高温工程塑料(如PA66),与-40℃~+105℃工作温度匹配,高温下无变形;
  • 插拔寿命:通常满足≥1000次插拔(满足设备多次维护的插拔需求)。

综上,PM254V-11-03-H85单排直插排母以高兼容性、紧凑结构、可靠性能为核心优势,是各类小型电子设备实现稳定电路连接的经济实用选择。

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
