CJT A2012WV-S-3P线对板针座产品概述

CJT(长江连接器)A2012WV-S-3P是一款针对线对板连接设计的表面贴装(SMD)针座,以2mm标准间距、3针单排结构为核心,兼顾电气性能、可靠性与安装便利性,适用于多种中低功率电子设备的信号/电源连接场景。

一、产品基本规格与定位

A2012WV-S-3P属于线对板连接器系列,核心规格明确:

  • 排数:1排,每排针数3,总PIN数3,插针结构1×3P;
  • 间距:2mm(符合电子设备常用间距标准,兼容性强);
  • 安装方式:立贴式SMD(表面贴装),适配自动化贴装生产线,无需插件后手工焊接;
  • 品牌与型号:CJT长江连接器,型号中“A2012WV-S”标识系列,“3P”明确针数。

该产品定位为小体积、高可靠的中低功率连接组件,填补了2mm间距SMD针座在小型设备中的应用空白。

二、核心电气性能参数

电气性能是连接器的核心指标,A2012WV-S-3P的关键参数满足多数实用场景:

  • 额定电流:3A(AC/DC通用),可稳定承载小型家电控制板、工业I/O模块的电源/信号电流,避免过流导致的接触失效;
  • 额定电压:250V(AC),符合家用220V及工业低压系统的电压要求;
  • 工作温度范围:-40℃~+105℃,覆盖工业环境(如户外设备低温、设备运行高温)与民用场景(如家电长时间工作的温度波动);
  • 触头镀层:锡镀层(Sn),兼具优异的焊接性(与PCB焊盘兼容性好,降低虚焊率)与抗氧化性(减少长期使用中的接触电阻增大问题)。

三、结构与材料设计特点

1. 触头结构:黄铜基底+锡镀层

触头采用黄铜(H65或类似牌号) 制作,黄铜导电率高(约28%IACS)、机械加工性好,可保证接触稳定性;表面镀锡厚度符合行业标准,既避免焊接时“吃锡”过度,又能长期保持接触可靠性(插拔过程中镀层不易脱落)。

2. 塑料主体:PA6T工程塑料

塑料外壳选用PA6T(聚对苯二甲酰己二胺),相比普通PA6、PA66具有更优的耐高温性(长期使用温度可达120℃以上,高于产品标称的105℃)、耐化学腐蚀性与机械强度;同时通过UL94V-0阻燃等级认证,燃烧时仅产生少量有毒烟雾,符合电子设备的安全规范。

3. 立贴安装设计

采用立贴式SMD封装,针脚垂直于PCB平面,相比卧式贴装节省更多PCB布局空间,适合小型化设备(如智能手环充电座、小型PLC模块);针脚长度与间距符合IPC标准,自动化贴装时定位精准,良率高。

四、应用场景与适配性

A2012WV-S-3P的规格与性能使其适用于以下场景:

  • 小型家电:电饭煲、加湿器、空气净化器的控制板电源/信号连接(额定3A可满足加热元件的小功率供电);
  • 工业控制:PLC(可编程逻辑控制器)的I/O接口、传感器模块的信号连接(宽温范围适应车间环境波动);
  • 消费电子:智能穿戴设备的充电座、蓝牙音箱的内部连接(立贴设计适配小体积PCB);
  • 汽车电子周边:车载USB充电模块、仪表盘辅助接口(-40℃~+105℃符合车载环境要求)。

适配线端连接器:可与CJT同系列线端连接器(如对应线端带锁扣设计)配合使用,形成完整的线对板连接系统,提升抗振动性能。

五、可靠性与市场价值

1. 可靠性优势

  • 触头黄铜+锡镀层:接触电阻稳定(初始接触电阻≤20mΩ),插拔寿命≥500次(行业标准测试);
  • PA6T塑料:耐冲击、耐老化,长期使用不变形;
  • 立贴封装:焊接牢固,抗振动性能优于插件式连接器(避免针脚松动)。

2. 市场价值

作为CJT的主流2mm间距SMD针座,A2012WV-S-3P兼具成本优势(黄铜与PA6T的性价比高)与批量生产兼容性(符合自动化贴装要求),适合家电、工业、消费电子等领域的量产需求,是替代进口同规格产品的高性价比选择。

总结:CJT A2012WV-S-3P以2mm间距、3针立贴SMD为核心,通过黄铜锡镀层触头、PA6T阻燃外壳的设计,实现了电气性能、可靠性与安装便利性的平衡,可满足多种中低功率电子设备的连接需求。

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
