CJT A2501WR-9P线对板针座产品概述

一、产品核心定位与典型应用场景

CJT(长江连接器)A2501WR-9P是一款XH系列衍生的单排弯插线对板针座,专为2.5mm间距的中低功率信号/电力传输场景设计,核心定位是替代传统直插针座,满足设备小型化、高密度PCB布局的需求。其典型应用覆盖三大领域:

  1. 消费电子:智能音箱、路由器、游戏机手柄等小型设备的内部模块连接(如电源板与控制板);
  2. 小型家电:豆浆机、加湿器、空气净化器的电机驱动、传感器信号传输;
  3. 工业控制:PLC扩展模块、小型传感器节点、低压配电盒的内部接线(3A额定电流可支撑小型继电器、LED阵列供电)。

二、基础参数全解析

A2501WR-9P的参数严格遵循XH系列标准,关键指标清晰适配常规应用:

  • 连接结构:单排9Pin(1×9P)设计,紧凑布局减少PCB占用面积;
  • 间距规格:2.5mm标准间距,与同系列线端连接器(如XH-9P端子线)完全兼容;
  • 安装方式:弯插式(直角插针),引脚垂直于针座主体,适合PCB侧面焊接,节省垂直空间(比直插减少约30%的设备厚度);
  • 电气性能:额定电流3A(AC/DC)、额定电压250V,满足大部分低压电器的功率需求;
  • 环境参数:工作温度范围-40℃~+105℃,可适应寒冷地区或高温工作环境(如家电内部散热区域);
  • 材料规格:触头采用黄铜(导电率高)+锡镀层(抗氧化、降低接触电阻),塑料主体为PA66(耐冲击、阻燃)。

三、关键性能优势

相比同类型直插针座,A2501WR-9P的核心优势体现在3个维度:

3.1 空间利用优化

弯插设计使引脚90°弯折,焊接后仅占用PCB侧面空间,适合薄型设备(如厚度≤10mm的智能音箱),避免直插针座突出设备外壳的问题。

3.2 接触可靠性

黄铜触头的导电率达25%IACS以上,锡镀层厚度≥5μm(行业标准),可有效降低接触电阻(≤20mΩ),且插拔过程中不易产生氧化层,多次插拔(≥500次)仍保持稳定连接,避免信号中断或功率损耗。

3.3 环境适应性

PA66塑料主体符合UL94V-0阻燃等级,遇火时仅自熄不蔓延,适合家电、工业设备等对安全要求高的场景;宽温范围覆盖-40℃(低温存储)至105℃(持续工作),可适应不同地域的环境温度变化。

四、材料与工艺特性

A2501WR-9P的材料选择兼顾性能与成本,工艺细节保障一致性:

  • 触头部分:黄铜原材料经过退火处理,硬度适中(HV120~150),既保证插针强度(不易弯曲),又能在插拔时与线端端子紧密贴合;锡镀层采用滚镀工艺,镀层均匀无漏镀,抗氧化能力提升3倍以上。
  • 塑料部分:PA66添加15%玻纤增强,提升耐冲击性(落锤测试无裂纹),且耐老化性能优异(长期使用无脆化);针座主体的定位柱设计,确保焊接时与PCB精准对齐,减少虚焊风险。

五、安装与兼容性说明

5.1 安装注意事项

  • 焊接温度:建议烙铁温度≤260℃,单个引脚焊接时间≤3秒,避免高温导致PA66塑料变形;
  • 定位要求:针座上的定位孔需与PCB对应定位柱配合,防止焊接后偏移;
  • 清洁要求:焊接前需去除PCB焊盘氧化层,焊接后用酒精清理残留助焊剂。

5.2 兼容性搭配

优先搭配CJT同系列线端连接器(如XH-9P端子线),或市场上通用的2.5mm间距XH系列端子线,确保连接紧密无松动;不建议搭配非XH标准的端子线,避免针脚磨损或接触不良。

六、安全与环保认证

A2501WR-9P符合多项行业标准:

  • 阻燃认证:UL94V-0(北美及国内主流标准);
  • 环保认证:RoHS 2.0(无铅、无镉、无汞等有害物质),满足欧盟及国内环保要求;
  • 电气安全:通过GB 13140.1-2008(低压电器安全标准)测试,可用于家用及类似用途设备。

总结:A2501WR-9P作为XH系列的弯插衍生产品,以紧凑设计、可靠性能和宽适应性,成为小型电子设备、家电及工业控制领域的优选连接组件,适合对空间、成本和可靠性有平衡需求的应用场景。

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.
