CJT A2547WV-2P线对板针座产品概述

一、产品核心定位与基本规格

CJT(长江连接器)A2547WV-2P属于单排直插式线对板针座,专为小功率电路的板端连接设计,适配1x2P插针布局,是行业通用2.54mm间距系列的基础款。其核心规格清晰明确:

  • 插针结构:单排2Pin(1×2P),总PIN数2P,无多余冗余结构;
  • 间距规格:2.54mm(行业标准间距,兼容性强,可直接适配同间距端子、线束);
  • 安装方式:插件式(直插PCB板,通过焊接固定,连接可靠性优于贴片式);
  • 尺寸设计:单排紧凑布局,针脚长度适配常规1.6mm厚PCB板,节省板内空间。

二、关键性能参数解析

该针座的性能参数覆盖多数常规应用场景的核心需求,具体解析如下:

  1. 电气性能:额定电流3A(AC/DC通用)、额定电压250V AC,满足小家电、小型工业控制等小功率传输需求;镀金触头使接触电阻≤20mΩ,信号/电流传输无明显压降,避免发热风险;
  2. 环境适应性:工作温度范围-40℃~+105℃,可覆盖低温环境(如北方户外设备周边)、高温环境(如烤箱、加热设备附近),适配复杂工况;
  3. 安全性能:塑料外壳阻燃等级达UL94V-0,遇火自熄不蔓延,符合电子设备防火标准;触头防腐蚀镀层,长期使用无氧化、接触不良问题。

三、材质与工艺设计优势

A2547WV-2P的材质选择兼顾性能、成本与可靠性,具体优势体现为:

  • 触头部分:黄铜基底+镀金表层。黄铜导电率约90%IACS(接近纯铜),成本低于纯铜;镀金表层厚度3~5μ",可有效防止触头氧化、腐蚀,降低接触电阻波动,提升长期连接可靠性;
  • 塑料外壳:PBT(聚对苯二甲酸丁二醇酯)材质,具备耐高温(短期耐120℃以上)、耐弱酸碱腐蚀、机械强度高的特点,配合UL94V-0阻燃等级,满足严苛环境安全要求;
  • 结构细节:直插针脚采用“倒钩+平整端面”设计,焊接时易定位,无虚焊风险;插针与外壳配合紧密,避免针脚晃动导致的连接失效。

四、典型应用场景

基于上述性能与规格,A2547WV-2P适用于以下领域:

  1. 消费电子:机顶盒、路由器、智能家居模块(如智能灯控)的内部板端连接,满足小功率信号与电流传输;
  2. 小家电:咖啡机、加湿器、电热水壶的控制板与电源线/传感器连接,宽温范围适配加热设备工作环境;
  3. 工业控制:小型PLC模块、传感器接口板的外部连接,3A电流支持多数传感器工作电流;
  4. 车载辅助设备:车载充电器、小尺寸显示屏的内部连接,温区覆盖车载环境(-40℃低温启动、高温暴晒稳定工作)。

五、产品合规与可靠性验证

CJT作为国内连接器知名品牌,A2547WV-2P需经过多重可靠性测试:

  • 机械测试:插针插拔力≥1N(符合行业标准),针脚焊接拉力≥5N,避免使用中松脱;
  • 环境测试:高低温循环(-40℃~+105℃,100循环)后性能无衰减;湿热测试(40℃/95%RH,96h)后接触电阻变化≤10%;
  • 安全认证:塑料外壳通过UL94V-0认证,部分批次符合RoHS环保标准(无铅、无镉),适配出口产品需求。

总结

A2547WV-2P是一款高性价比的通用线对板针座,凭借2.54mm标准间距、宽温适应性、镀金触头可靠性,成为小家电、消费电子、工业控制等领域的常用选择,可有效降低设备连接成本的同时保障稳定性能。

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
