CJT A2008WV-2X4P 线对板针座产品概述

CJT(长江连接器)A2008WV-2X4P是一款2mm间距双排直插式线对板针座,专为中小功率电路的信号与电力传输设计,兼顾电气性能、环境适应性与成本优势,适配多领域电子设备的连接需求。

一、产品基本属性

该针座的核心结构与识别参数清晰明确,便于快速选型匹配:

  • 布局类型:2排×4针(2x4P),总PIN数8P,双排间距(行距)2mm;
  • 安装方式:插件(直插式),适合PCB板焊接固定,无需额外工具即可完成初步定位;
  • 系列兼容性:参考PH系列连接器,与同间距、同针数的线端连接器完全匹配,可直接替换同规格竞品;
  • 品牌与型号:CJT原厂出品,型号A2008WV-2X4P(其中“2X4P”明确针数布局,“WV”对应优化的焊接工艺等级)。

二、核心性能参数

产品性能覆盖电气、环境与机械维度,满足多数常规应用场景的核心需求:

  • 电气性能:额定电流3A(AC/DC通用)、额定电压250V,可承载中小功率设备的电力传输(如小型电机、LED模组供电),同时满足信号传输的低阻抗要求(接触电阻≤20mΩ);
  • 环境适应性:工作温度范围-40℃至+105℃,支持工业级宽温场景(如户外传感器、车载电子),避免极端温度下塑料变形或触头氧化;
  • 机械性能:2mm针距为行业通用标准,插针定位精度≤0.05mm,双排结构提升连接稳定性(抗振动性能优于单排),直插设计便于焊接操作,减少安装误差。

三、材料与工艺特点

材料选型与工艺细节决定了产品的可靠性与耐用性,具体特点如下:

  • 触头系统:采用黄铜材质(导电率≥58%IACS,满足电流传输效率),表面镀纯锡(镀层厚度3~5μm)——镀锡层可有效抗氧化、降低接触电阻,同时与锡焊工艺完美兼容,避免虚焊问题;
  • 塑料主体:选用PA46(聚酰胺46) 材料,相比普通PA66,其连续使用温度可达120℃以上(高于产品额定105℃),机械强度提升约20%,抗冲击性能优异;阻燃等级达到UL94V-0(垂直燃烧测试,火焰移开后10秒内自熄),符合电子设备的安全规范;
  • 制造工艺:插针与塑料主体采用精密注塑嵌件成型,插针无松动、偏移问题;镀层均匀性经盐雾测试(48小时)验证,无明显腐蚀,确保长期使用可靠性。

四、典型应用场景

该针座因尺寸紧凑、性能均衡,广泛适配以下场景:

  1. 智能家居与消费电子:智能音箱控制板、智能门锁接线端、小型投影仪接口;
  2. 小型家电:咖啡机、加湿器、空气净化器的电路连接(如显示模组与主板对接);
  3. 工业控制:小型PLC扩展接口、传感器模块(温度/压力)与控制器的信号连接;
  4. 车载电子:车载小屏控制器、车内氛围灯电源接口(符合-40~105℃宽温要求);
  5. 医疗设备:血糖仪、血压计的电池接口或传感器连接端(低电流传输需求)。

五、选型与安装注意事项

为确保连接可靠性,需注意以下要点:

  • 选型匹配:对插的线端连接器需为2x4P、2mm间距的PH系列,避免公母针距/针数不匹配导致连接不良;若应用电流接近3A,需选用≥0.5mm²的导线(避免线阻过大发热);
  • 焊接安装:直插焊接时,温度控制在250~260℃,单个引脚焊接时间≤3秒,避免高温损坏PA46塑料;焊接后需用酒精清理助焊剂残留,防止腐蚀触头;
  • 存储维护:未使用的针座需存放在干燥环境(湿度≤60%),避免阳光直射与化学溶剂接触,存储温度0~40℃,防止塑料老化或镀层氧化。

该产品凭借成熟的结构设计、可靠的材料选型与广泛的兼容性,成为中小功率电子设备线对板连接的高性价比选择,适配多领域的标准化连接需求。

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
