CJT A2012WVA-2P 线对板针座产品概述

CJT(长江连接器)A2012WVA-2P是一款专为线对板连接设计的直插式针座,采用2mm间距单排2Pin结构,兼顾紧凑性与电气可靠性,广泛适配于小型电子设备的内部信号/电力传输需求。以下从核心参数、结构设计、材质特性、应用场景等维度展开概述。

一、核心基础参数梳理

该产品关键参数明确,可满足多数常规电子设计的匹配需求:

  • 结构参数:单排2Pin设计(1×2P),针脚间距2mm,总PIN数2P,符合工业标准紧凑布局要求;
  • 安装方式:直插式(插件)封装,适配PCB板焊盘安装,工艺兼容性强;
  • 电气参数:额定电流3A(AC/DC通用),额定电压250V(符合安全认证标准),工作温度范围-40℃至+105℃;
  • 材质参数:触头采用黄铜基底+锡镀层,塑料壳体为PA66工程塑料,阻燃等级达UL94V-0;
  • 品牌型号:CJT(长江连接器)原厂出品,型号A2012WVA-2P,可追溯至正规供应链。

二、结构设计与安装优势

A2012WVA-2P的结构设计聚焦“紧凑性+安装便利性”:

  1. 小间距紧凑布局:2mm间距是电子连接器主流规格,可在有限PCB空间内实现2Pin信号/电力传输,尤其适合小型化设备(如便携电子、小型家电);
  2. 直插式封装适配:直插设计无需额外工具,可通过波峰焊或手工焊完成PCB固定,降低生产工艺复杂度;
  3. 针座结构稳定性:塑料壳体采用一体化注塑成型,针脚固定牢固,避免插针松动导致的接触不良问题。

三、材质特性与可靠性保障

产品材质针对电气性能与环境适应性优化:

  • 触头部分:黄铜具有优异导电性、耐磨性与机械强度,表面锡镀层可将接触电阻稳定在低毫欧级,同时提升抗氧化能力,避免长期使用中因氧化导致的接触失效;
  • 塑料壳体:PA66工程塑料匹配-40℃~+105℃工作温区,具备良好耐温性、机械强度与耐化学腐蚀性;UL94V-0阻燃等级可在意外短路时阻止火焰蔓延,符合电子设备安全规范;
  • 长期可靠性:黄铜锡镀触头可承受≥500次常规插拔,塑料壳体无老化开裂风险,适合长期稳定运行的电子设备。

四、典型应用场景

作为线对板针座,A2012WVA-2P覆盖多个领域:

  1. 小型家用电器:电饭煲、加湿器、台灯、电水壶等设备的内部电源/信号连接(如控制板与加热元件、传感器的连接);
  2. 消费电子:智能穿戴(手环、手表)、便携音箱、移动电源等的内部板端连接;
  3. 工业控制设备:小型PLC模块、传感器节点、继电器模组的信号传输接口;
  4. 汽车电子辅助模块:车载充电器、氛围灯、小功率传感器(如温度传感器)的板端连接(匹配汽车级温区需求)。

五、适配与使用注意事项

为确保性能,使用时需注意:

  1. PCB焊盘匹配:需采用2mm间距、2Pin直插对应的焊盘设计,避免间距偏差导致安装困难;
  2. 焊接工艺:手工焊建议用≤350℃低温锡丝,避免高温损坏塑料壳体;波峰焊需遵循连接器焊接曲线(峰值温度≤260℃,时间≤10秒);
  3. 线材适配:搭配22AWG~26AWG常规线材,确保端子与针座接触紧密;
  4. 环境要求:避免在强酸强碱、相对湿度>95%环境下长期使用,特殊环境需咨询原厂确认。

总结:CJT A2012WVA-2P线对板针座凭借紧凑结构、可靠材质与宽温适应性,成为小型电子设备内部连接的高性价比选择,符合CJT连接器品质标准,可满足多数常规电子设计的性能需求。

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
