A2012WVA-4P 线对板针座产品概述

A2012WVA-4P是长江连接器(CJT) 推出的一款2mm间距单排4Pin直插式线对板针座,专为中低功率电子设备的稳定连接设计,兼具紧凑性、可靠性与环境适应性,适用于多类工业及消费电子场景。

一、产品核心定位与典型应用场景

该产品属于通用型中功率线对板连接方案,聚焦“小体积、稳定传输、宽温适配”三大核心需求,典型应用覆盖以下领域:

  1. 工业控制场景:PLC(可编程逻辑控制器)的数字量I/O扩展模块、小型电机驱动辅助接口、传感器(如温度、压力传感器)与控制板的连接;
  2. 消费电子场景:智能家居设备(智能开关、温湿度传感器)、小型家电(如加湿器、智能台灯)的内部控制板连接;
  3. 汽车电子场景:车载小功率传感器(如车内温度传感器、座椅传感器)的信号/低电流连接;
  4. 通信辅助场景:小型基站(如微基站)的辅助模块(如电源分配、信号转接)连接。

二、关键参数与性能指标

产品参数经过标准化设计,兼顾电气性能、机械强度与环境适应性,核心指标如下:

类别 具体参数 备注 电气参数 额定电流3A(AC/DC)、额定电压250V 满足中低功率设备传输需求 机械参数 1x4P单排结构、间距2mm、直插安装 紧凑布局,节省PCB空间 环境参数 工作温度-40℃~+105℃、UL94V-0阻燃 适应极端温度与防火要求 材料参数 触头:黄铜+锡镀层;壳体:PA66 耐氧化、高机械强度

三、结构设计与材料特性

1. 触头系统:稳定导电+耐老化

触头采用黄铜基底+锡镀层设计:

  • 黄铜导电率高(约100%IACS),接触电阻低(<20mΩ),保证信号/电流传输损耗小;
  • 表面锡镀层厚度均匀(通常≥5μm),有效防止触头氧化、腐蚀,延长插拔寿命(可达500次以上),避免因氧化导致的接触不良。

2. 塑料壳体:高可靠+防火安全

壳体选用PA66(尼龙66) 材料:

  • 机械强度高(拉伸强度≥80MPa),耐冲击、耐振动,适合工业设备的震动环境;
  • 耐温性能优异(长期使用温度可达120℃),匹配产品工作温度范围;
  • 阻燃等级UL94V-0,遇火难燃且自熄(燃烧时间≤10s),符合工业设备的防火安全标准。

3. 结构布局:紧凑易安装

  • 单排4Pin设计:间距2mm(行业通用间距),布局紧凑,可节省PCB板约10%的安装空间,适合小型化设备;
  • 直插式引脚:引脚长度合理(通常≥1.5mm),焊接时易定位,避免虚焊,提升生产效率。

四、安装与可靠性优势

1. 安装便捷

直插式设计无需特殊工具,直接插入PCB焊盘即可焊接,配合自动插件设备可实现批量生产,降低人工成本。

2. 连接稳定

与CJT同系列线端连接器(如对应线对板的端子)配合紧密,接触压力均匀,插拔时无卡顿,长期使用不易松动,避免因连接不良导致的设备故障。

3. 环境适应性强

  • 宽温范围(-40℃~+105℃)可覆盖北方冬季户外设备、南方夏季车间等极端温度场景;
  • PA66壳体耐湿热(相对湿度≤95%),适合潮湿环境(如工业厂房、沿海地区设备)。

4. 寿命长

锡镀层减少触头氧化,黄铜触头保证长期导电稳定,壳体耐老化,产品使用寿命可达10年以上(符合工业设备长期使用需求)。

五、品牌与品质保障

长江连接器(CJT)作为国内连接器行业的资深厂商,拥有10余年的电子连接方案研发经验,A2012WVA-4P具备以下品质优势:

  1. 认证齐全:符合RoHS环保标准,通过UL、CE等认证,满足国内外市场准入要求;
  2. 批量一致性:采用自动化生产工艺,产品尺寸公差控制在±0.1mm以内,批量生产一致性好;
  3. 兼容性强:2mm间距单排4Pin为通用规格,可匹配市场上多数同参数线端连接器,降低系统设计成本。

综上,A2012WVA-4P线对板针座凭借紧凑结构、稳定性能与宽温适配性,成为工业控制、消费电子等领域中低功率连接的优选方案,可有效提升设备的可靠性与生产效率。

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
