MOLEX 22272021 连接器产品概述

一、产品基本定位与应用场景

MOLEX 22272021属于线到板(Wire to Board)连接器,定位为通用型小功率连接方案,适配空间紧凑、电气性能稳定要求较高的场景。典型应用覆盖多领域:

  • 工业控制:PLC(可编程逻辑控制器)I/O接口、小型变频器的信号/电源连接;
  • 消费电子:智能插座、加湿器等小型家电的内部组件连接;
  • 医疗设备:便携式监护仪、输液泵等低功率模块的信号传输;
  • 通信设备:小型路由器、交换机的辅助电源/信号接口。

其2.54mm标准间距与1x2P布局,兼容多数常规电路板设计,无需特殊定制板型。

二、核心电气性能参数

产品核心电气参数决定适用功率范围,关键指标如下:

  • 额定电流:4A/每PIN(持续工作电流,需匹配线径使用);
  • 额定电压:500V AC(或DC,以官方规格书为准),绝缘性能满足高电压场景安全要求;
  • 触头材质:黄铜基底(高导电性、机械强度好)+锡镀层(优异焊接性、抗氧化性,无铅环保);
  • 接触电阻:通常<10mΩ,减少信号衰减与功率损耗;
  • 间距:2.54mm(国际标准,兼容同类2.54mm间距连接器)。

三、机械结构与材质特性

机械设计兼顾紧凑性与可靠性,核心特性包括:

  • 插针布局:1排2PIN(1x2P),总PIN数2,适合单路信号/电源连接;
  • 塑料外壳:PA(聚酰胺)材质,耐冲击、耐弱酸弱碱,热变形温度>100℃,可承受焊接瞬时高温;
  • 阻燃等级:UL94V-0(高阻燃,燃烧自熄无滴落,符合工业与医疗设备安全规范);
  • 外观颜色:白色,便于电路板上快速识别,减少安装错误。

四、封装与安装方式

封装与安装适配常规生产流程:

  • 封装类型:插件式(Through-Hole),操作简便,适合手工焊接或波峰焊;
  • 安装方式:顶部插入焊接(Top Entry),插针从电路板顶部插入焊盘,底部焊接;
  • 引脚间距:2.54mm,兼容面包板、通用电路板焊盘布局;
  • 包装形式:KK Bag(防静电塑料袋),每袋数量按规格而定(如500只/袋),防静防尘,便于仓储取用。

五、可靠性与环境适应性

产品满足工业级可靠性要求:

  • 耐温范围:-40℃至105℃,适应宽温环境(如北方户外设备、南方高温车间);
  • 抗氧化性:锡镀层触头存储期>1年,接触电阻稳定;
  • 插拔寿命:经测试达数百次(官方数据为准),适合需要频繁维护的设备;
  • 耐振抗冲击:符合IEC 60068-2-6(振动)、IEC 60068-2-27(冲击)标准,可承受工业环境中的机械应力。

六、选型与搭配建议

使用时需注意以下要点:

  1. 线端搭配:建议使用MOLEX同系列2.54mm间距、2PIN线端,确保物理与电气匹配度;
  2. 线径选择:4A电流需配合0.5mm²(AWG 20)及以上线径,避免线径过细导致发热;
  3. 焊接控制:焊接温度<350℃(波峰焊<260℃),防止PA外壳变形;
  4. 绝缘距离:500V电压需确保相邻连接器或元件的绝缘距离符合安全标准;
  5. 储存条件:常温(15-35℃)、干燥(相对湿度<60%)、防静电环境储存,避免阳光直射与化学腐蚀。

该产品凭借稳定的电气性能、可靠的机械结构与广泛的兼容性,成为小功率连接场景的优选方案,可满足多数工业、消费电子与医疗设备的连接需求。

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
