CJT A2005HWV-2X4P 连接器产品概述

一、产品基本定位与应用场景

CJT(长江连接器)A2005HWV-2X4P是一款双排直插式连接器,专为中小功率电气设备的信号/电源传输设计。核心规格为2×4P(共8个插孔)、2mm中心间距,适配常规PCB板布局,广泛应用于以下领域:

  • 工业自动化:PLC模块、传感器接口、小型控制器;
  • 仪器仪表:便携式测试设备、计量仪器、医疗诊断终端;
  • 智能家居:智能网关、传感器节点、小型家电控制板;
  • 通信设备:光模块子板、接入网设备的辅助接口。

该产品通过紧凑结构实现多通道传输,兼顾电气可靠性与安装便利性,满足多数中低端应用场景的核心需求。

二、核心参数与结构设计

1. 结构规格

  • 排数与孔位:双排布局,2×4P(8个独立插孔),单排4孔,中心间距2mm;
  • 插孔类型:顶部方孔设计(区别于常规圆孔),方孔与端子接触面积更大,抗振动时接触稳定性更优;
  • 安装方式:直插式(通孔焊接),触头尾部为引脚式,直接插入PCB焊盘,适配手工/自动焊接;
  • 触头材质:磷青铜(CuSn)——弹性优异、导电率高,长期使用不易疲劳变形;
  • 触头镀层:表面镀金(Au)——防止触头氧化,降低接触电阻,提升插拔寿命。

2. 尺寸适配

遵循2mm间距连接器标准规范,PCB焊盘无需特殊设计,可直接替换同类竞品,降低设计成本。

三、电气性能指标

该产品经严格测试,满足工业级应用要求:

  • 额定电流:单孔2A(AC/DC),总负载需按实际孔位计算(如8孔全用≤16A,需注意散热);
  • 额定电压:250V AC/DC(有效值),覆盖低压电气设备电压范围;
  • 接触电阻:初始≤20mΩ(典型值),镀金触头长期保持低电阻,避免发热;
  • 绝缘电阻:常态(25℃/60%RH)≥1000MΩ,湿热环境(40℃/95%RH)≥100MΩ,无相邻插孔漏电;
  • 耐电压:AC 500V(50Hz)1分钟测试,无击穿、飞弧,符合IEC 60947标准。

四、环境适应性

具备宽范围环境耐受能力,适合复杂工况:

  • 工作温度:-40℃~+105℃——覆盖低温(北方户外)与高温(工业控制柜)场景,触头弹性无明显衰减;
  • 耐温稳定性:+105℃连续工作1000小时,触头无软化、镀层无脱落;-40℃插拔100次,无接触不良;
  • 耐盐雾/潮湿:通过IEC 60068-2-11盐雾测试(96小时),表面无腐蚀;潮湿环境绝缘电阻仍达标;
  • 抗振动冲击:符合IEC 60068-2-6振动测试(10~2000Hz,10g加速度),无端子脱落或电阻突变。

五、安装与使用注意事项

  1. 焊接工艺:PCB焊盘孔径0.8~1.0mm,焊接温度≤260℃(避免损坏镀金层),单引脚焊接时间≤3秒;
  2. 端子匹配:使用CJT配套2mm间距方孔端子(如A2005系列),垂直插入避免触头变形;
  3. 清洁维护:触头沾染油污/灰尘时,用无水乙醇擦拭,晾干后使用;
  4. 负载限制:严禁单孔电流超2A,过载会导致触头发热、镀层氧化;
  5. 插拔寿命:镀金触头插拔≥500次(典型值),频繁插拔需保持端子匹配。

总结

CJT A2005HWV-2X4P作为高性价比双排直插连接器,凭借紧凑结构、稳定性能、宽环境适应性及简单安装,成为工业控制、仪器仪表等领域的实用选择。方孔设计与镀金触头进一步提升接触可靠性,适合成本敏感但需保证基本性能的场景。

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
