A2508WR-3P 产品概述

A2508WR-3P 为 CJT(长江连接器)XA 系列的线对板弯插针座,1x3P、节距 2.5mm,专为小型化电路中可靠的线对板连接而设计。该型号以紧凑的外形、可靠的电气性能及良好的阻燃和耐温特性,适用于家电、工业控制、灯具及各类电子产品内部电源或信号连接场合。

一、主要参数与结构特点

  • 引脚排列:单排 1x3P,总针数 3P。
  • 节距(P):2.5mm,适配常见 2.5mm 间距线端/插拔式连接件。
  • 安装方式:弯插(右角/弯脚插装),便于电路板边缘或垂直方向安装线缆连接。
  • 额定电流:3A(单针额定电流,具体应用请考虑整体散热与温升)。
  • 额定电压:250V(交流/直流常规额定值)。
  • 工作温度:-40℃ 至 +105℃(取决于系统整体温度环境)。
  • 触头材质:黄铜基材,触点表面镀锡,提高焊接性与防氧化能力。
  • 塑料材质:PA66,阻燃等级 UL94V-0,具较好机械强度与耐热性。
  • 系列参考:XA;封装形式:弯插,P=2.5mm。

二、产品优势(性能与可靠性)

  • 结构紧凑:2.5mm 节距与 1x3P 组合使得该针座在有限 PCB 面积上能实现稳定的三路连接。
  • 良好导电与接触可靠性:黄铜触点配合镀锡处理在常规电流及环境下能保证低接触电阻与较好的长期可靠性。
  • 阻燃与耐温:PA66(UL94V-0)外壳能在一般电子设备工作环境中提供必要的防火与机械保护。
  • 多场景安装:弯插式设计便于在边缘装配或柜体侧面布线,便于线缆管理与外壳配合。
  • 工艺兼容性:适用于常规的手工焊接与波峰/回流等通过孔插装工艺(建议在生产前结合工艺条件验证)。

三、常见应用场景

  • 小型电源模块、开关电源辅助连接与引出。
  • 家电控制板内部电源/信号连接(例如显示/按键模块连线)。
  • 工业控制设备的低功率控制回路连接。
  • LED 驱动、照明电源和其他电子整机的线对板接口。
  • 仪器仪表、安防设备等需要可拆卸连接的内部布线场合。

四、选型与兼容性建议

  • 线规建议:针对 3A 额定电流,常用导线可选 2226 AWG(约 0.30.5 mm² 范围),具体选型请结合线缆长度、散热与允许压降计算。
  • 母端/配套线束:A2508WR-3P 作为公针(板端)通常与配套的 3P 母端接插件或线束相配合。选购线束时注意配合 2.5mm 节距与锁紧/卡扣结构。
  • PCB 布局:弯插针座在 PCB 上占用空间小,布线时应预留足够的边缘间距与机械固定孔位,必要时增加锁紧柱或固定螺丝以提升抗拔力。
  • 孔径与焊盘:具体 PCB 钻孔与焊盘尺寸请参照厂方 PCB 安装图纸或样板件,建议在批量生产前先确认钻孔与波峰焊兼容性。

五、安装与使用注意事项

  • 焊接工艺:标准手工焊接与波峰焊通常可行,但在波峰或回流工艺中应控制高温暴露时间,避免塑料件变形或性能劣化。建议先获取样件做工艺验证。
  • 防松与应力:弯插式结构在插拔或拉力作用下会产生机械应力,装配时应避免对单针施加过大外力,必要时使用固定结构或丝扣固定。
  • 环境适应:尽管工作温度范围为 -40℃ ~ +105℃,在极端温度或高湿环境下应注意防腐蚀与绝缘保持,必要时考虑防护涂层或密封处理。
  • 维护与更换:长期使用后如发现接触不良、氧化或机械损伤,应及时更换。触点经过镀锡处理,可通过清洁或更换线端处理接触问题。

六、订购信息与技术支持

  • 型号:A2508WR-3P
  • 品牌:CJT(长江连接器)
  • 封装/形式:弯插,节距 2.5mm,1x3P
  • 若需批量采购或索取 3D/2D 尺寸图、PCB 安装模板、材料与可靠性测试报告(如耐温、耐振动等),建议直接联系供应商或指定代理商获取完整数据手册与样品验证支持。

总结:A2508WR-3P 属于结构简洁、性能稳定的 2.5mm 间距弯插线对板针座,适用于多种中低功率线对板连接场景。选用时请结合实际电流、温度及装配工艺做进一步验证,以确保长期运行可靠。

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
