CJT A2543WR-2P-2线对板针座产品概述

一、产品定位与核心价值

CJT A2543WR-2P-2是长江连接器(CJT)推出的通用型线对板连接组件,针对2.54mm标准间距设计,采用2P单排弯插结构,兼顾电气性能、安装灵活性与环境可靠性,适用于家电、小型工业、消费电子等多领域的低功率电路连接需求。其核心价值在于以紧凑结构实现稳定电流传输,同时满足宽温、阻燃等安全要求,降低系统设计的兼容性成本。

二、基本结构与规格参数

该针座的结构与规格符合行业通用标准,关键参数清晰明确:

  • 插针布局:1×2P单排设计,总PIN数2,每排2针,结构紧凑,可有效节省PCB板空间;
  • 间距规格:中心距2.54mm,与同类2.54mm间距的连接器/端子兼容,便于系统选型与替换;
  • 安装方式:弯插式引脚(引脚呈90°弯曲),适合PCB板垂直或侧面安装,适配不同设备的内部空间布局;
  • 尺寸兼容性:采用行业通用的2.54mm间距+2P单排结构,可匹配常规PCB板的焊盘设计,无需额外调整。

三、电气性能指标

电气性能是连接组件的核心,A2543WR-2P-2的关键指标满足多数低功率场景需求:

  • 电流承载:额定电流4A(AC/DC通用),在2.54mm间距产品中属于中等偏上水平,可支持小型电机、加热元件等负载;
  • 电压额定:250V(AC),符合家用及工业低压电路的安全电压要求,避免过压击穿风险;
  • 触头性能:触头采用黄铜材质(高导电率、良好弹性),表面镀锡(抗氧化、焊接性优异),可有效降低接触电阻(通常≤10mΩ),减少能量损耗与信号干扰。

四、机械与安装性能

机械性能直接影响连接的可靠性与安装效率:

  • 安装可靠性:弯插式引脚设计,焊接时可通过PCB焊盘紧密固定,避免引脚松动;弯曲结构可缓冲轻微机械应力,减少引脚断裂风险;
  • 插拔适配:与CJT配套的线端端子插拔配合紧密,插拔力适中(行业经验值1-5N),既保证连接牢固,又便于维护时拆卸;
  • 结构强度:塑料基座采用PA66材质,具有较高抗冲击、抗变形能力,可承受常规安装及使用中的机械碰撞。

五、材料与环境可靠性

该产品针对恶劣环境做了优化,可靠性突出:

  • 塑料材质:PA66(尼龙66),耐温性、耐化学性优异,可抵抗轻微油污、酸碱腐蚀;
  • 阻燃等级:UL94V-0级(高阻燃),遇明火时快速自熄,有效降低设备起火风险,符合安全认证要求;
  • 工作温度范围:-40℃+105℃,覆盖家用(-10+60℃)、工业(-20~+85℃)及部分户外场景的温度需求,低温下不脆化、高温下不变形。

六、典型应用场景

结合性能特点,A2543WR-2P-2适用于以下场景:

  1. 家电领域:电饭煲、电水壶、微波炉等小型厨电的电源/控制电路连接;
  2. 小型工业设备:传感器模块、小型PLC控制器、低压电源适配器的内部连接;
  3. 消费电子:机顶盒、路由器、智能家居设备(智能灯、传感器)的内部排线连接;
  4. 汽车电子:车载小功率部件(车内照明、传感器辅助电路)的连接(适配车载-40~+85℃环境)。

七、总结

CJT A2543WR-2P-2作为高性价比线对板针座,以标准2.54mm间距、2P弯插结构为核心,兼顾电气性能(4A/250V)、环境可靠性(宽温+阻燃)、安装灵活性,是多领域低功率电路连接的理想选择。黄铜镀锡触头、PA66阻燃基座的设计,确保长期使用的稳定性与安全性,适合对成本敏感且要求可靠连接的系统设计。

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
