CJT A1502-TP胶壳端子产品概述

CJT(长江连接器)推出的A1502-TP胶壳端子,是针对24~28AWG细导线设计的小型化连接组件,以磷青铜触头、锡镀层为核心,兼顾电气稳定性与成本控制,覆盖家电、工业控制、通信等多领域的中低端位连接需求。

一、核心定位与应用场景

A1502-TP定位于小型化高性价比连接组件,聚焦24~28AWG细导线的可靠接线,避免大线规端子的体积冗余,典型应用场景包括:

  • 家电领域:空调、洗衣机、微波炉等设备的内部控制线束连接;
  • 工业控制:PLC模块、传感器、小型继电器的接线端子;
  • 通信设备:路由器、交换机、光模块的内部信号/电源连接;
  • 汽车电子:车载信息娱乐系统、低压传感器的线束接口。

二、关键技术参数详解

A1502-TP的核心参数围绕导线适配性与电气可靠性设计,具体如下:

  • 导线适配:线规24~28AWG,允许绝缘外径≤1.1mm(避免线径过粗/过细导致压接不良);
  • 触头性能:材质为磷青铜(C5191/C5210),表面镀纯锡(厚度≥2μm);
  • 电气参数:额定电压350V AC/DC,24AWG导线适配时建议额定电流≤10A,28AWG≤5A(参考行业标准);
  • 环境参数:工作温度范围-40℃~105℃,接触电阻≤10mΩ(初始状态),绝缘电阻≥1000MΩ(常态)。

三、材料与工艺优势

A1502-TP的材料选择与工艺设计兼顾性能与成本:

  1. 磷青铜触头:弹性模量达110GPa,插拔时接触力稳定,可承受≥50次插拔无性能衰减;抗应力松弛能力强,长期使用不会因触头变形导致接触不良。
  2. 纯锡镀层:相比镀金镀层成本降低60%以上,具备良好焊接性(可直接焊锡),耐一般环境腐蚀(湿度≤80%、无强酸碱)。
  3. 双压接结构:线芯压接区(覆盖金属芯)保证电流传输稳定,绝缘压接区(覆盖绝缘层)提升拉力强度(24AWG导线压接后拉力≥10N,28AWG≥5N),避免导线脱落。

四、可靠性验证

A1502-TP通过多项行业标准测试,确保长期稳定运行:

  • 插拔寿命测试:≥50次插拔后,接触电阻变化≤10%,无触头变形/脱落;
  • 振动测试:符合IEC 60068-2-6标准(振动频率10~2000Hz,加速度2g),测试10小时后无松动、接触不良;
  • 温度循环测试:-40℃(2h)→105℃(2h)循环1000次,绝缘电阻≥500MΩ,接触电阻≤15mΩ;
  • 耐盐雾测试:96小时中性盐雾测试后,触头无明显腐蚀,接触电阻变化≤5%。

五、安装与适配要点

为保证使用效果,需注意以下安装细节:

  1. 导线预处理:24AWG导线剥线1.52mm,28AWG剥线11.5mm(避免线芯过长短路、过短影响压接);绝缘外径需≤1.1mm。
  2. 压接工具:需使用CJT专用压接钳(型号A1502-CR)或匹配模具,避免手工压接导致的接触不良;压接后检查压接区是否紧密贴合。
  3. 胶壳适配:配合CJT同系列胶壳(如A1502系列)使用,确保端子卡扣与胶壳定位槽精准配合,无松动。
  4. 使用注意:避免端子过度弯折(弯折半径≥3mm),保持端子清洁(油污、灰尘会影响接触性能)。

六、市场价值与定位

A1502-TP凭借以下优势成为中低端连接市场优选:

  • 成本优势:磷青铜+纯锡镀层组合,成本比镀金端子低50%以上,适合批量采购;
  • 小型化适配:端子长度≤10mm,可满足小型化设备的内部空间需求;
  • 品质保障:符合RoHS、REACH环保标准,长江连接器(CJT)可提供稳定供货周期。

综上,A1502-TP是24~28AWG导线连接的高性价比方案,兼顾性能、可靠性与成本,覆盖多领域稳定连接需求。

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
