A2543WV-3P线对板针座产品概述

A2543WV-3P是长江连接器(CJT)推出的一款直插式线对板针座,专为低压中小功率设备的信号与电力传输设计,凭借紧凑结构、稳定性能及宽环境适应性,广泛应用于家电、工业控制等领域。

一、产品基本属性

该针座采用单排3Pin设计(1×3P),引脚间距为行业通用的2.54mm,适配多数标准连接器及导线端子。安装方式为直插式插件,可直接焊接于PCB板,无需额外工具辅助,安装效率较高。产品总PIN数为3,每排3Pin,结构简洁,占用PCB空间小,适合紧凑型设备布局。

二、核心性能参数

2.1 电气性能

  • 额定电流:4A(AC/DC),满足一般中小功率设备的电力传输需求,如家电控制板、小型传感器供电;
  • 额定电压:250V(AC/DC),适用于低压电路系统,符合多数民用及工业低压设备的电压规范;
  • 接触电阻:≤20mΩ(典型值),触头接触电阻低,确保信号传输稳定,无明显压降。

2.2 环境适应性

  • 工作温度范围:-40℃~+105℃,覆盖低温(如北方户外设备)及高温(如家电内部发热环境)场景,长期使用可靠性高;
  • 阻燃等级:UL94V-0,塑料主体遇火时可快速自熄,避免火势蔓延,符合安全标准要求;
  • 耐温冲击:PA66塑料材质可承受短期高温冲击(如焊接时的局部高温),不易变形开裂。

三、材料与工艺特点

3.1 触头系统

  • 触头材质:黄铜(H65牌号),导电性能优异,机械强度高,反复插拔或振动下不易变形;
  • 触头镀层:表面镀锡,可有效防止触头氧化,提升焊接兼容性(与锡铅、无铅焊料均适配),同时降低接触电阻,延长使用寿命。

3.2 绝缘主体

  • 塑料材质:PA66(聚酰胺66),具有良好的耐冲击性、耐化学腐蚀性及耐温性,长期使用不易老化;
  • 成型工艺:采用精密注塑,引脚定位精准(公差±0.1mm),与配套端子插拔配合紧密,减少接触不良风险。

四、典型应用场景

A2543WV-3P因结构紧凑、性能稳定,广泛应用于以下领域:

  1. 家电领域:空调、洗衣机、冰箱的控制板与外部导线连接,耐温性能适配家电内部发热环境;
  2. 工业控制:PLC(可编程逻辑控制器)、传感器、小型电机的信号/电力接口,4A电流满足小功率传输需求;
  3. 消费电子:机顶盒、路由器、智能音箱的内部接线,2.54mm间距适配标准端子,安装便捷;
  4. 汽车电子:车载小功率设备(如仪表盘辅助模块、倒车雷达)的连接,-40℃~+105℃温度范围符合车载环境要求。

五、安装与选型注意事项

5.1 选型要点

  • 确认需求PIN数为3Pin(1×3P),间距2.54mm,避免与其他间距(如2.0mm、3.96mm)混淆;
  • 结合应用场景的电流、电压及温度范围,确认是否匹配4A/250V/-40℃~+105℃参数。

5.2 安装建议

  • 焊接时采用合适的焊接温度(260℃~280℃,单个引脚焊接时间≤3秒),避免过度加热导致塑料主体变形;
  • 直插时确保引脚与PCB焊盘对齐,焊接后清理残留焊料,避免短路;
  • 存储时置于干燥、常温环境(温度0℃~40℃,湿度≤60%),避免阳光直射及腐蚀性气体接触。

六、总结

A2543WV-3P作为一款高性价比的直插式线对板针座,兼具稳定的电气性能、宽环境适应性及便捷的安装方式,可满足多数中小功率设备的连接需求,是家电、工业控制等领域的可靠选择。

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
