菲尼克斯1751264螺钉式接线端子产品概述

一、产品核心参数与基础定位

菲尼克斯1751264属于工业级螺钉式直插接线端子,专为PCB板上的信号与中等功率传输设计,核心参数精准匹配常规工业设备需求:

  • 机械结构:1排4针(1×4P)布局,针距3.5mm,直插式安装(插件封装);
  • 电气性能:额定电流13.5A/极,额定电压200V;
  • 适配范围:导线线规兼容16AWG(约1.3mm²)至30AWG(约0.05mm²),覆盖细信号导线到中等功率导线;
  • 外观材质:绿色阻燃工程塑料外壳,直观区分功能模块,同时满足安全防护要求。

二、结构设计与工艺优势

该端子聚焦可靠性与空间效率,针对工业场景严苛要求优化:

  1. 紧凑针距布局:3.5mm针距在保证电气间隙(≥1.5mm)与爬电距离(≥2mm)合规的前提下,大幅节省PCB空间,适合微型PLC、便携式测试仪器等小型化设备;
  2. 螺钉连接可靠性:采用高强度钢质螺钉+螺纹自锁设计,拧紧后可长期保持连接压力,避免电机、风机等振动源导致的接触松动;
  3. 阻燃绝缘外壳:外壳材质为PA66(聚酰胺66),符合UL94 V-0最高阻燃等级,耐温范围-40℃至+120℃,适应高低温交替的工业环境;
  4. 直插引脚优化:引脚镀锡处理,焊接润湿性好,减少虚焊风险;引脚长度与间距精准匹配标准PCB焊盘,支持自动化插件工艺。

三、电气性能与安全合规

1751264的性能满足工业级安全标准,核心指标包括:

  • 绝缘性能:常温下绝缘电阻≥1000MΩ,耐电压测试通过2.5kV/1min(符合IEC 60950-1),防止漏电与短路;
  • 电流承载能力:13.5A额定电流可稳定承载持续负载,短时间1.5倍过载下仍保持性能稳定,适合电机控制、电源输出等场景;
  • 安全认证:通过UL、VDE、CE等权威认证,可直接用于出口设备或国内高端工业项目,无需额外认证;
  • 接触电阻:端子与导线接触电阻≤10mΩ(初始状态),长期使用变化量小,保证信号传输准确与功率损耗可控。

四、典型应用场景

该端子适配多领域工业设备,常见应用包括:

  1. 工业控制:PLC输入输出模块、伺服驱动器信号接口、变频器控制接线;
  2. 电力电子:开关电源输出端子、UPS电池连接、逆变器低压控制端;
  3. 通信物联网:基站电源模块、工业路由器电源/信号接线、边缘计算设备接口;
  4. 新能源配套:充电桩低压控制接线、储能系统电池管理单元(BMU)接口;
  5. 小型设备:便携式测试仪器、医疗监护仪电源接口、智能家居控制模块内部接线。

五、安装与维护注意事项

为确保长期可靠运行,需注意以下要点:

  1. 安装前准备:确认PCB焊盘间距匹配,避免引脚弯曲;剥线长度控制在5-6mm(过短接触不良,过长易短路);
  2. 焊接规范:手工焊接温度260℃±10℃,时间≤3s(避免外壳熔化);波峰焊需设置合适预热温度;
  3. 导线连接:螺钉拧紧扭矩0.5-0.8N·m(用扭矩螺丝刀),避免过紧损伤导线/端子,过松导致接触电阻增大;
  4. 日常维护:每6个月检查螺钉松动、导线氧化(氧化则重新剥线);用压缩空气清洁端子表面灰尘油污;
  5. 环境限制:禁止直接用于强酸强碱等腐蚀性环境(如需选带防护涂层型号),避免超过-40℃至+120℃温度范围。

六、产品价值总结

菲尼克斯1751264凭借紧凑结构、可靠性能与宽适配性,成为工业设备PCB接线的高性价比选择,尤其适合对空间、电流承载与安全合规有要求的场景,可有效提升设备集成效率与长期稳定性。

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
