CJT A2541HWR-2P 排母产品概述

一、产品核心定位与基本规格

CJT(长江连接器)推出的A2541HWR-2P是一款专为2.54mm标准间距设计的单排弯插方孔排母,聚焦小功率信号/电源连接场景,主打紧凑空间适配与可靠接触性能。其核心基础规格明确:

  • 结构:单排1×2P插孔,间距2.54mm(行业通用标准);
  • 安装:弯插式+侧面插孔,塑高仅2.5mm,针脚长度3.2mm;
  • 触头:黄铜材质+镀金镀层,方孔设计提升接触稳定性。

二、关键结构设计优势

1. 方孔触头优化接触可靠性

区别于常规圆孔排母,该产品采用方孔插孔:与配套针脚接触时面积更大,可分散接触压力,减少振动、冲击下的接触不良风险;黄铜触头兼具良好导电性(电阻率低)与机械强度(抗插拔磨损),表面镀金则能降低接触电阻(通常<20mΩ) 、提升抗腐蚀能力(避免氧化导致的信号衰减/电源中断),长期使用可靠性显著高于普通镀锡产品。

2. 弯插侧面设计适配紧凑布局

采用侧面插孔+弯插安装方式:可实现PCB板侧面出线,避免正面插孔占用设备正面空间,适合手持仪器、车载配件等小型化设备;塑高仅2.5mm,配合3.2mm针脚长度,与常规PCB过孔(φ0.8~1.0mm)适配性良好,焊接时无需担心针脚过长干涉其他元件,也不会因过短导致虚焊。

三、电气性能与环境适应性

1. 电气参数覆盖小功率需求

额定电流3A、额定电压250V,可满足两类核心场景:

  • 信号传输:传感器信号、控制信号(如PLC输入输出);
  • 低功率电源:5V/12V供电(如小型控制器、LED模块)。
    结合镀金触头设计,绝缘电阻>1000MΩ,耐电压能力达AC 500V/1min(无击穿),符合一般电子设备的电气安全标准。

2. 宽温域与抗环境能力

工作温度范围为**-40℃~+105℃**,覆盖三类典型场景:

  • 工业控制:低温车间(-20℃左右)、高温控制柜(+85℃左右);
  • 消费电子:夏季户外设备(+40℃以上);
  • 车载配件:高低温循环环境(-30℃~+85℃)。
    镀金镀层可抵抗轻度潮湿、盐雾(符合GB/T 2423.17标准),黄铜触头的机械强度支持≥500次插拔(行业常规测试值),适合需要反复维护的设备。

四、典型应用场景

A2541HWR-2P的紧凑结构与可靠性能,使其适配多类场景:

  • 小型电子仪器:万用表附件、便携式示波器接口、小型信号发生器;
  • 消费电子配件:智能插座控制模块、小型蓝牙音箱电源接口;
  • 工业控制模块:小型PLC输入输出接口、传感器信号转接板;
  • 车载辅助设备:后视镜控制器接口、小功率LED氛围灯电源接口。

五、安装与可靠性要点

1. 焊接注意事项

弯插安装时需注意:

  • 针脚与PCB过孔对齐,避免倾斜;
  • 焊接温度控制在260℃±5℃,单个针脚焊接时间≤3秒(避免塑壳受热变形,塑壳采用耐高温工程塑料);
  • 优先使用无铅焊锡,符合RoHS环保要求。

2. 接触可靠性维护

  • 镀金镀层无需额外抗氧化处理,长期使用无需清洁;
  • 建议配套CJT同系列针座(如A2541HWR配套针座)使用,确保接触匹配度;
  • 避免频繁插拔超过额定次数(500次),防止触头磨损。

3. 空间布局建议

  • 侧面插孔方向需提前规划,避免与PCB板上的电容、电阻干涉;
  • 塑高2.5mm可支持多排密集布局,适合多接口的小型设备。

总结

CJT A2541HWR-2P是一款高性价比的2.54mm间距排母,通过方孔触头+弯插侧面设计实现了紧凑空间与可靠接触的平衡,宽温域、抗腐蚀性能满足工业、消费电子、车载等多场景需求,是小型电子设备连接方案的理想选择。

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
