CJT A2008WVA-4P 线对板针座产品概述

一、产品定位与核心用途

CJT A2008WVA-4P是一款单排4Pin线对板针座,隶属于长江连接器(CJT)PH系列,采用2.0mm间距直插式设计,核心作用是实现导线与PCB板之间的可靠电气连接,适配PH系列端子使用,广泛覆盖中小功率电子设备的内部布线场景。

二、核心参数详解

该针座的关键参数完全匹配常规电子设备的连接需求,具体如下:

  • 针座规格:1排4针(1×4P),总PIN数4,针距2.0mm(P=2mm),符合PH系列标准接口;
  • 安装方式:插件式(直插),适配PCB板插件焊接工艺,支持手工/自动化生产;
  • 电气性能:额定电流3A,额定电压250V(AC/DC通用),工作温度范围-40℃至+105℃;
  • 材料组成:触头为黄铜基材+锡镀层;塑料壳体为PA66材质,阻燃等级UL94V-0;
  • 机械特性:插针固定牢固,壳体强度高,插拔过程无明显变形。

三、结构设计与材料优势

3.1 紧凑空间适配

采用单排4Pin布局+2.0mm间距设计,相比多排针座节省30%以上PCB空间,适合小型化设备(如智能穿戴、小型家电)的内部布线,避免布局拥挤。

3.2 触头性能优化

  • 黄铜基材:高导电率(≈1.6×10^8 S/m),接触电阻稳定在10mΩ以内,降低信号/功率损耗;
  • 锡镀层:厚度≥5μm,提升焊接兼容性(易上锡、无虚焊),同时防止触头氧化,延长使用寿命至500次插拔以上。

3.3 阻燃耐温壳体

  • PA66工程塑料:耐高低温(-40℃~+105℃),可适应北方低温、南方高温环境;
  • UL94V-0阻燃:遇火30秒内自熄不延燃,符合电子设备安全标准,降低火灾风险。

3.4 直插安装适配

插针长度精准(8.0±0.2mm),定位孔与PCB板匹配度≥98%,减少手工焊接误差;支持自动化插件设备,提升生产效率20%以上。

四、性能可靠性与适用场景

4.1 电气可靠性

额定3A电流满足中小功率电路(如5V/2A电源输出、TTL信号传输)需求,长期工作无明显温升(≤10℃),避免因过热导致的连接失效。

4.2 环境适应性

  • 耐潮湿:PA66壳体吸水率≤1.2%,可适应湿度85%RH的环境;
  • 耐化学腐蚀:能抵抗弱酸碱、酒精等常见溶剂,适合工业现场使用。

4.3 典型应用领域

  • 消费电子:加湿器、台灯、扫地机器人、智能音箱的内部线板连接;
  • 工业控制:小型PLC模块、传感器节点、工业电源的信号/电源连接;
  • 汽车电子:车载充电器、氛围灯、倒车雷达辅助模块的内部布线;
  • 通讯设备:小型交换机、无线AP、光纤收发器的内部排线连接。

五、品牌与品质保障

长江连接器(CJT)是国内连接器行业的主流品牌,A2008WVA-4P通过RoHS 2.0、UL 1439认证,每批次产品均经过:

  • 电气性能测试(接触电阻、绝缘电阻);
  • 机械强度测试(插拔寿命、振动试验);
  • 环境可靠性测试(高低温循环、湿热试验)。 产品品质一致性达99.5%以上,可满足客户批量生产需求。

该针座凭借紧凑设计、可靠性能与高性价比,成为中小功率电子设备线板连接的优选方案。

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
