T44080080-0850 PCB焊接端子产品概述

一、产品核心定位与适用场景

T44080080-0850是XFCN(兴飞)品牌推出的M4规格插件式PCB焊接端子,专为PCB板与外部导线/连接器的可靠连接设计,核心定位为工业级中低功率电路的信号/电力传输接口。该端子兼顾安装便捷性、导电稳定性与耐环境性,可替代传统接线端子简化布线,避免虚接风险,适用于大多数电子设备内部的接线需求。

二、关键参数与结构设计

1. 核心规格参数

  • 螺孔规格:M4标准螺纹(螺距0.7mm,螺纹深度≥6mm,满足常规螺栓紧固);
  • 焊脚数量:4个直插焊脚(长度10±0.5mm,适配1.6mm标准PCB板);
  • 额定参数:额定电流20A(AC/DC通用),额定电压250V(AC)/300V(DC);
  • 环境范围:工作温度-40℃105℃(工业级),存储温度-55℃125℃。

2. 结构设计特点

  • 端子主体一体化冲压成型,无拼接缝隙,接触电阻≤0.5mΩ;
  • 焊脚与主体一体化设计,避免焊接脱焊;
  • 绝缘外壳采用PA66尼龙,边缘倒圆角防刮PCB板;
  • 螺孔内置防松结构,配合平垫圈可降低振动环境下松动概率。

三、材料与工艺特性

1. 主体材料

  • 导电部分:高纯度H65黄铜,导电率≥58%IACS(比普通铜材提升5%);
  • 绝缘部分:增强级PA66尼龙,符合UL94 V-0阻燃标准,耐120℃短期高温。

2. 表面处理工艺

  • 导电端子:镀锡(Sn),镀层厚度2~3μm,抗氧化能力强,焊接无需额外助焊剂;
  • 绝缘外壳:哑光黑色注塑,耐油污、酒精/丙酮等工业溶剂,便于设备内部识别。

四、安装与焊接注意事项

1. PCB板设计要求

  • 焊盘孔径:1.2~1.3mm(适配焊脚直径1.0mm),焊盘间距≥2.5mm(防短路);
  • 端子底部预留0.5mm间隙,避免焊接时绝缘壳受热变形。

2. 焊接工艺规范

  • 波峰焊:温度240260℃,焊接时间35秒(过长易氧化焊脚);
  • 手工焊:烙铁350~380℃,焊接时间≤2秒,用低残渣焊锡丝;
  • 焊点检查:4个焊脚需形成饱满焊点(无虚焊、桥接)。

3. 螺栓紧固规范

  • 扭矩:M4螺栓0.8~1.2N·m(过紧易滑丝,过松易松动);
  • 导线连接:优先用OT冷压端子压接,避免裸导线直接连接(防接触不良)。

五、典型应用领域

该端子因性能稳定、安装便捷,广泛用于:

  1. 工业控制:PLC、变频器、伺服驱动器的电源/信号接线;
  2. 电源设备:开关电源、UPS、LED驱动电源的输出接线;
  3. 通信设备:路由器、交换机、光模块的信号接口;
  4. 家电控制:洗衣机、空调、冰箱的主控板接线;
  5. 新能源:小型充电桩、光伏逆变器的辅助电路接线。

六、选型匹配要点

若替代或匹配该端子,需确认:

  • 螺孔是否为M4(不可混M3/M5);
  • 4焊脚间距是否匹配PCB布局;
  • 额定电流是否覆盖电路需求(超20A需选更大规格);
  • 工作温度是否适配环境(户外需确认耐低温)。

该端子经振动测试(10~2000Hz,加速度10g)、盐雾测试(48h)等可靠性验证,可满足工业与民用设备长期稳定运行,是PCB接线的高性价比选择。

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
