A2008WR-3P 产品概述

一、产品简介

A2008WR-3P 是 CJT(长江连接器)推出的一款 1x3P 弯插线对板针座,间距 2.0mm,参考系列为 PH。该产品面向小型电子设备的线对板连接需求,结合紧凑的 2.0mm 间距与右角(弯插)安装形式,便于在密集布线和空间受限的电路板上实现可靠的电气连接。

二、主要参数与材料

  • 插针结构:1x3P(单排 3 针)
  • 间距(Pitch):2.0 mm(PH 系列兼容)
  • 安装方式:弯插(右角/侧装,通过 PCB 安装)
  • 额定电流:3 A(单针)
  • 额定电压:250 V
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 触头材质:黄铜(Brass)
  • 触头镀层:镀锡(Tin)
  • 塑料材料:PA66,阻燃等级 UL94 V-0
  • 引脚总数/排数:总 PIN 数 3P,排数 1,单排 3 个 PIN
  • 参考系列:PH(与常见 PH 系列插针/插座配合使用)

三、结构与安装方式

A2008WR-3P 采用弯脚(Right-angle)引脚设计,适用于侧向出线或在 PCB 边缘处实现紧凑接口布局。通过式(插入式)设计便于波峰或手工焊接,焊盘与机械固位配合良好,能够在有限高度空间内实现可靠的电气和机械连接。与 PH 系列兼容的间距与针形使其可与常用的插拔式母端子/线束连接器配合使用。

四、产品特点与优势

  • 小型化设计:2.0mm 间距与 1x3P 配置,节省 PCB 空间,适合紧凑型电路布局。
  • 可靠的导电性能:黄铜触头保证良好导电性,镀锡处理提高焊接性与耐腐蚀性。
  • 耐热与阻燃:PA66 塑料本体并达到 UL94 V-0 评级,适应工业及消费电子的常见安全要求。
  • 宽温工作范围:-40 ℃ ~ +105 ℃,适合一般室温及部分工业环境使用。
  • 兼容性好:参考 PH 系列标准,易于与现成母端、端子盒、线束配合,从而方便产品设计和采购对接。
  • 适合波峰/手工焊接:弯插结构支持常见的通过孔焊接工艺,焊点牢靠、装配效率高。

五、典型应用场景

  • 小型家电与消费类电子的电源/信号连接(如 LED 灯带、控制板连接)。
  • 工业控制板、传感器模块与外部线束间的低压电源或信号连接。
  • 通信设备、仪器仪表、物联网终端等对空间与可靠性有一定要求的 PCB 连接点。
  • 需要侧向出线或 PCB 边缘接口的设备结构设计。

六、选型与使用建议

  • 导线匹配:鉴于单针额定电流为 3A,建议搭配的导线截面积大致在 0.2~0.5 mm²(约 AWG 24~20)范围,根据实际电流裕度选择更粗或更细线材。
  • 焊接工艺:本产品适用于波峰焊和手工焊接。PA66 工作温度上限为 105 ℃,在焊接时应避免长时间高温暴露,推荐采用合适的焊接节拍与预热工序以保护塑料件。
  • PCB 布局:为保证机械强度,建议在 PCB 设计时为弯脚端子预留足够的焊盘面积与焊锡保护区,并考虑在插拔或受力位置附近增加机械固定或胶粘点以增强振动耐受性。
  • 互换与兼容:如需与市场上常用 PH 系列母端配合,应确认母端子与插针的插合深度与导电件形状以确保良好接触与插拔寿命。

七、包装、储存与可靠性注意事项

  • 包装:出厂通常采用防潮包装以防止触点氧化和塑件受潮变形。
  • 储存:建议存放于干燥、常温环境,避免阳光直射、高温与强酸碱环境。长期存储前应避免接触腐蚀性气体。
  • 可靠性试验:在设计关键产品时,建议对连接器进行通电老化、振动与热循环试验验证,在实际工况下确认接触可靠性与机械寿命。

总结:A2008WR-3P 为一款面向紧凑型 PCB 方案的 2.0mm 间距 1x3P 弯插针座,兼顾小体积与 3A 的电流承受能力,采用黄铜触头镀锡与 PA66 UL94 V-0 塑料材料,适用于多种消费电子与工业控制场景。选型时注意导线匹配、焊接工艺与 PCB 机械加强设计,以保证长期可靠运行。

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
