A2505WV-3P 产品概述

A2505WV-3P 为 CJT(长江连接器)系列中一款标准直插式线对板插针座,采用 1x3P 单排结构,间距(Pitch)2.5mm,适用于小型化电路板与连接线之间的可靠连接。产品以黄铜触头、锡镀层和PA66阻燃塑料为主要材料,兼具耐用性与良好的电气性能,适合消费电子、工业控制、仪器仪表等多种场景下的线对板连接需求。

一、产品概述与亮点

  • 型号:A2505WV-3P
  • 品牌:CJT(长江连接器)
  • 结构:直插(Through‑hole)1×3P,单排3PIN
  • 间距:2.5mm(适配常见 2.5mm PCB 布局)
  • 封装形式:插件(Through‑hole)

亮点:

  • 紧凑小型化设计,适合空间受限的电路板布局;
  • 黄铜触头、锡镀层,保证良好导电性与焊接性能;
  • 外壳采用 PA66 材料并达 UL94V‑0 阻燃等级,安全性高;
  • 额定 3A/250V,满足中低功率连接需求。

二、主要技术参数

  • 插针结构:1×3P(单排)
  • 间距(Pitch):2.5mm
  • 安装方式:直插(Through‑hole)
  • 总 PIN 数:3P
  • 额定电流:3A
  • 额定电压:250V
  • 触头材质:黄铜
  • 触头镀层:锡
  • 塑料材质:PA66
  • 塑料阻燃等级:UL94V‑0
  • 工作温度范围:‑40℃ ~ +105℃

(以上为常用规格,具体机械尺寸及耐久性参数请参考厂家详细资料或样品确认。)

三、结构与材料特性

  • 触头:采用黄铜基材,具备较好的导电性能与机械强度;表面锡镀层提升了焊接性,适合波峰焊或手工焊接工艺。锡镀层在一般环境下提供良好接触与焊接可靠性,但在高腐蚀性环境中耐蚀性不如金镀层。
  • 塑料件:PA66 本体材料,具备良好的热稳定性与机械强度,并达到 UL94V‑0 阻燃等级,适用于对安全性有一定要求的应用场景。
  • 机械结构:1×3 单排直插结构,使安装与手工/自动插件作业方便,适配常见 PCB 直插孔工艺。

四、电气与环境性能

  • 额定电流 3A:适用于信号线和中小功率供电线路,建议在长期或高温工况下适当留有裕量。
  • 额定电压 250V:满足普通低压电子设备的隔离与连接要求。
  • 温度范围 ‑40℃ ~ +105℃:可用于常见工业与民用环境,但在高温或高湿度、腐蚀性环境需综合评估。
  • 建议注意触头接触电阻与长期接触可靠性,定期检查焊点与插拔部位以防氧化或虚焊。

五、安装与焊接建议

  • 安装方式:通过孔直插,适配常规 PCB 孔径与机械固定要求。
  • 焊接工艺:推荐采用波峰焊或手工焊接;对于波峰焊,请按工艺规范控制焊接温度与时间,避免塑件变形。由于为插件件,不建议进行回流焊。
  • 强度与支撑:在需要频繁插拔或承受力矩的应用场景,应在 PCB 侧增加机械支撑或采用线夹进行应力缓解,避免焊点疲劳损坏。
  • 清洗:若需清洗 PCB,采用对锡镀触头温和的清洗剂并尽量避免长期浸泡,以防影响镀层与塑料件。

六、典型应用场景

  • 家用电器与消费电子的小型连接接口
  • 工业控制板、仪表与数据采集模块的电源/信号连接
  • 通信设备内置线对板连接
  • 教育与实验板、原型开发板快速连接模块

七、选型与维护建议

  • 选型时确认实际电流与使用环境,若存在持续大电流或高温环境,应选择额定电流/温度更高的型号或增加散热、降额使用。
  • 若环境具有高湿度、盐雾或腐蚀性气体,建议考虑金镀或其他耐腐蚀表面处理的触头以提高长期可靠性。
  • 对于需频繁插拔的应用,建议做耐久性测试并与厂家确认插拔次数寿命。
  • 订购前请确认 PCB 孔径、插针长度及高度等机械尺寸,确保与板上布局和外壳配合。

八、包装与订购信息

  • 封装:插件(Through‑hole),适用于 SMT 之外的传统插件生产线。
  • 备货/订购:请注明型号 A2505WV-3P、数量与交期;如需样品或制作带有特殊镀层/定制引脚长度,可与 CJT 或授权代理商沟通确认。

如需完整机械图、针位图和焊盘尺寸图纸,或材料与可靠性测试报告,建议联系 CJT(长江连接器)获取原厂 Datasheet 及工程支持,以便在设计与量产阶段保证兼容性与可靠性。

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
