DC-044A-A250 DC电源插座产品概述

DC-044A-A250是讯普(XUNPU)推出的一款弯插式DC电源插座,针对中低功率直流供电场景设计,兼顾空间紧凑性、安装便捷性与电气可靠性,广泛适配消费电子、小型工业、医疗辅助设备等领域的供电需求。

一、产品核心定位与应用场景

该产品核心定位为小型低压设备的直流供电接口,聚焦3A以下持续负载的应用场景,解决传统直插式插座占用PCB垂直空间的问题,尤其适合对设备体积有严格要求的设计。其典型应用场景包括:

  • 家用数码:路由器、机顶盒、智能音箱等小型家电的电源输入接口;
  • 工业控制:PLC辅助电源模块、传感器节点的供电端;
  • 消费配件:移动电源输出插座、LED台灯/小夜灯的电源接口;
  • 医疗辅助:便携式血压计、雾化器等低压医疗设备的供电端(符合30V安全电压要求)。

二、关键参数与性能指标

DC-044A-A250的参数设计贴合常规低压设备需求,核心指标明确:

  1. 尺寸规格:触点内径2.5mm(匹配市场主流DC插头内针),外径5.9mm(兼容标准DC插头套筒),弯插结构(90°角度)减少PCB垂直方向占用空间(约节省10-15mm高度);
  2. 电气性能:额定电流3A(持续负载下无明显发热),额定电压30V DC(符合国家低压设备安全规范),接触电阻≤50mΩ(确保电能传输效率);
  3. 环境适应性:工作温度范围-20℃至+70℃,可满足室内常温、户外短期暴露(如庭院LED灯)等环境;存储温度-40℃至+85℃,适应运输与仓储的温湿度变化;
  4. 封装与安装:插件式封装,引脚长度适配标准PCB厚度(1.6mm),弯插设计便于布局时避开其他元件,适合波峰焊、手工焊等组装工艺。

三、结构设计与安装特性

产品结构设计突出紧凑性与可靠性:

  • 弯插结构优势:相比直插式,弯插后插座高度仅约8mm(含引脚),大幅降低设备内部垂直空间占用,适配超薄机顶盒、小型手持设备等设计;
  • 触点耐磨设计:采用黄铜镀镍触点(行业常规耐磨导电材料),插拔寿命≥1000次(模拟日常使用3-5年的插拔频率),避免长期使用后接触不良;
  • 安装便捷性:插件式引脚无需特殊焊接工具,批量生产时可通过自动插件机快速组装,手工焊时焊点易成型,牢固度符合电子组装行业标准。

四、品牌与可靠性保障

讯普(XUNPU)作为国内专注连接器领域的品牌,DC-044A-A250经过多重可靠性测试:

  • 插拔寿命测试:1000次插拔后仍保持接触电阻≤80mΩ;
  • 高低温循环测试:-20℃至+70℃循环50次后,电气性能无衰减;
  • 环保认证:符合RoHS 2.0标准(无铅、无镉、无汞等有害物质),适配欧盟市场需求;
  • 一致性保障:批量生产中参数偏差≤5%,避免不同批次产品兼容性问题。

五、适配注意事项

使用时需注意以下细节:

  1. 插头匹配:需选用内针2.5mm、套筒5.9mm的DC插头,避免尺寸不符导致插拔困难或接触不良;
  2. 负载限制:持续负载电流不得超过3A,短期脉冲电流(≤10s)不得超过5A,防止触点过热;
  3. 安装方向:弯插角度为90°,需确认PCB布局时引脚方向与设备内部空间匹配;
  4. 焊接温度:手工焊时烙铁温度≤350℃,焊接时间≤3s,避免高温损坏塑料外壳。

总结:DC-044A-A250凭借弯插紧凑设计、可靠电气性能与适配性,成为小型低压设备DC供电接口的高性价比选择,适合量产设备的稳定供应与个性化设计需求。

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
