CJT A3963WR-3P线对板针座产品概述

一、产品定位与核心参数概览

CJT A3963WR-3P是长江连接器(CJT)推出的VH系列中等功率线对板针座,聚焦紧凑空间下的稳定电流传输需求。核心参数明确:采用1×3P单排结构,针距3.96mm(VH标准间距),弯插插件安装方式,总PIN数3P。该型号适配工业控制、小型家电等场景,兼顾安装便利性与电气可靠性,是替代进口同类型号的高性价比选择。

二、结构设计与材质特性

2.1 触头系统

触头基底选用高导电黄铜,导电率达行业标准(≥15%IACS),可有效降低电流传输损耗;表面镀纯锡(镀层厚度≥5μm),既符合RoHS环保要求,又能防止触头氧化,提升插拔循环寿命(支持≥500次插拔后仍保持稳定接触)。

2.2 塑料壳体

壳体采用PA66(聚酰胺66) 材质,具备三重优势:

  • 机械性能:抗冲击强度≥80J/m,耐磨损,多次插拔不出现壳体开裂;
  • 耐温性:长期工作温度范围-40℃~+105℃,短期可承受120℃高温;
  • 阻燃性:UL94V-0级阻燃,遇明火30秒内自熄,满足设备安全防火要求。

三、电气性能关键参数

该针座的电气参数针对性适配中等功率场景:

  • 额定电流:10A(AC/DC通用),在3.96mm间距线对板针座中属于较高水平,可满足小型电机、电源模块(如5V/2A、12V/0.8A)的电流需求;
  • 额定电压:250V(AC),符合低压电气设备安全规范;
  • 接触电阻:出厂测试初始值≤20mΩ,长期使用后仍稳定在≤50mΩ,避免因接触不良导致的发热或信号中断。

四、安装与适配性

4.1 安装方式

采用弯插插件封装,安装时将针脚垂直插入PCB板后弯折(或与PCB板呈90°焊接),相比直插安装节省30%以上的垂直空间,适合设备内部布局紧凑的场景(如小型家电控制板、嵌入式模块)。

4.2 适配兼容性

遵循VH系列标准接口,可与同系列VH-3P端子(如CJT VH-3P压接端子)直接配合使用,无需额外适配件;1×3P单排结构支持灵活扩展(如需5P、8P可选择同系列多排型号),降低系统设计复杂度。

五、环境适应性与可靠性

该针座通过多轮环境测试,可靠性符合工业级标准:

  • 温湿度循环:通过-40℃~+85℃/95%RH循环测试(100次),壳体无变形、触头无氧化;
  • 盐雾测试:5%NaCl溶液喷雾48小时后,触头无腐蚀,接触电阻变化≤10%;
  • 振动测试:符合GB/T 2423.10标准(10~2000Hz,加速度20m/s²),连接无松动。

六、典型应用场景

因紧凑结构与高电流能力,该型号广泛应用于:

  1. 小型家电:咖啡机、加湿器、空气净化器的控制板与电源模块连接;
  2. 工业控制:PLC I/O接口、传感器模块(如温度/压力传感器)的信号/电源连接;
  3. 消费电子:小型打印机、路由器的电源输入接口、内部模块(如WiFi模块)连接;
  4. 汽车周边:车载充电器、行车记录仪的内部电路板连接(适配非核心系统的环境温度范围)。

七、品牌与质量保障

长江连接器(CJT)作为国内连接器行业头部厂商,该型号具备:

  • 认证齐全:通过UL(E347544)、RoHS、REACH认证,符合全球市场准入要求;
  • 生产稳定:采用自动化冲压、注塑工艺,触头尺寸公差≤±0.05mm,批量供货一致性高;
  • 服务灵活:支持小批量定制(如特殊镀层、颜色),常规型号库存充足,交货周期≤3天。

该型号凭借“高电流、紧凑结构、可靠耐用”的核心优势,已成为众多家电、工业设备厂商的首选连接方案之一。

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
