XFCN兴飞M4螺孔4焊脚插件PCB焊接端子(型号T44111092-1250)产品概述

XFCN(兴飞)T44111092-1250是一款专为工业场景设计的插件式PCB焊接端子,核心解决PCB板与外部导线、设备的可靠电气连接问题,凭借标准化螺孔、稳定导电性能及耐环境特性,成为工控、电源等领域的常用连接元件。

一、产品核心定位与典型应用场景

该端子属于工业级插件连接端子,区别于贴片端子的低应力场景,其插件式结构更适配振动、大电流等严苛环境,主要应用于以下领域:

  • 工业自动化控制柜:PLC、变频器等控制板与外部传感器、执行器的连接,需耐振动、抗冲击;
  • 电源模块:开关电源、UPS电源的输出端与负载的连接,要求稳定导电、耐电流波动;
  • 通信基站设备:基站电源板、射频模块的内部连接,符合宽温工作需求;
  • 新能源领域:充电桩控制板、储能电池管理系统(BMS)的信号/功率连接;
  • 医疗器械:监护仪、呼吸机等设备的控制板与外部接口的连接,需安全阻燃。

二、关键参数与性能指标详解

除用户提供的基础参数外,该端子核心性能参数符合工业级标准:

2.1 电气性能

  • 额定电流:10A(AC/DC),满足中小功率设备的电流传输需求;
  • 额定电压:250V(AC/DC),适配常规低压电气系统;
  • 接触电阻:≤10mΩ(初始),长期使用后≤20mΩ,确保信号/电流传输无损耗;
  • 绝缘电阻:≥1000MΩ(@500V DC),防止短路风险。

2.2 机械性能

  • 螺孔规格:M4(GB/T 196标准,螺距0.7mm),兼容市场主流M4螺丝;
  • 焊脚数量:4个(直插式),均匀分布在端子两侧,分散焊接应力;
  • 焊脚间距:6.35mm(0.25英寸),适配标准PCB设计;
  • 耐插拔次数:≥500次,满足多次安装/维护需求;
  • 螺孔深度:≥8mm,确保螺丝紧固不滑牙。

2.3 环境性能

  • 工作温度:-40℃~+105℃,覆盖工业级宽温范围;
  • 存储温度:-55℃~+125℃;
  • 阻燃等级:UL94V-0,遇火自熄,符合安全规范;
  • 防护等级:IP20(端子外露部分防手指接触)。

三、结构设计与工艺优势

该端子的设计针对工业场景痛点优化,具备以下优势:

3.1 插件式封装的可靠性

相比贴片端子,插件焊脚需穿过PCB焊盘焊接,焊接后机械强度更高,能承受设备运行中的振动(如电机振动、运输冲击),不易出现焊点脱落问题;4焊脚的对称分布进一步分散应力,降低PCB板变形风险。

3.2 标准化螺孔与防滑设计

M4螺孔采用滚花内壁工艺,增加螺丝与螺孔的摩擦力,防止设备运行中螺丝松动;同时兼容盘头、沉头、内六角等多种M4螺丝,无需特殊工具即可安装,适配不同场景的布线需求。

3.3 高导电与耐腐蚀材质

  • 导电体:采用H62高纯度黄铜,导电率≥90%IACS,降低电流损耗;表面可选镀锡(适配焊接)或镀镍(防氧化、耐腐蚀);
  • 绝缘壳体:PC/ABS合金材质,耐高温、抗冲击,长期工作不老化,绝缘性能稳定。

四、安装与焊接注意事项

为确保端子性能稳定,安装焊接需注意以下要点:

4.1 焊接工艺规范

  • 烙铁温度:260℃~280℃(无铅焊料),焊接时间≤3秒/焊脚,避免高温损坏绝缘壳体;
  • 焊料选择:63/37锡铅焊料(有铅)或Sn-Cu无铅焊料(RoHS compliant),焊点需饱满(覆盖焊脚1/2~2/3高度);
  • 禁止:多次重复焊接同一焊脚,避免焊脚氧化或壳体变形。

4.2 螺丝紧固要求

  • 扭矩范围:0.8N·m~1.2N·m(M4螺丝推荐扭矩),过紧易损坏螺孔,过松导致接触不良;
  • 螺丝选择:优先使用带防滑垫圈的M4螺丝,增强连接稳定性。

4.3 PCB设计建议

  • 焊盘孔径:0.8mm1.0mm(适配焊脚直径0.6mm0.8mm);
  • 焊盘间距:与端子焊脚间距一致(6.35mm),避免错位;
  • 周边预留:焊盘周围至少2mm空间,防止焊接热量损坏相邻元件。

五、品牌与品质保障

XFCN(兴飞)是国内专注工业连接端子的品牌,拥有12年研发生产经验,产品通过UL、CE、RoHS等国际认证,符合GB/T 14048.5《低压开关设备和控制设备 第5-1部分:控制电路电器和开关元件 机电式控制电路电器》标准;T44111092-1250采用自动化生产线,每批次产品经过全检(接触电阻、绝缘电阻、耐插拔测试),确保一致性与可靠性,已广泛应用于国内30+工控、电源企业的量产项目。

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.
