CJT A2505WR-3P 线对板针座产品概述

CJT(长江连接器)A2505WR-3P是一款针对小功率电路线对板连接优化的3针弯插连接器,以2.5mm通用间距为核心,兼顾电气性能、环境适应性与安装灵活性,广泛适配小型家电、仪器仪表等领域的紧凑布局需求。以下从核心参数、结构工艺、性能表现等维度展开详细概述:

一、核心规格参数总览

该产品核心参数覆盖连接结构、电气性能、材料特性三大维度,清晰定义了应用边界:

  • 连接结构:单排3针(1×3P),针距2.5mm(行业通用标准,兼容多数同间距线端连接器);安装方式为弯插(引脚向侧面弯折,减少垂直空间占用);
  • 电气参数:额定电流3A/针,额定电压250V(交流/直流通用),满足多数小功率负载需求;
  • 材料特性:触头采用黄铜(高导电率)+ 锡镀层(优焊接性、防氧化);塑料外壳为PA66(高机械强度),阻燃等级UL94V-0(符合安全标准);工作温度范围-40℃~+105℃(宽温适配)。

二、结构设计与工艺特点

A2505WR-3P的结构设计围绕“紧凑安装+可靠连接”优化,解决小空间场景的连接痛点:

  • 弯插安装:引脚弯折角度适配PCB板侧面焊接,可在设备内部垂直空间有限的场景(如小型家电控制板、智能门锁模块)实现高密度布局,避免直插连接器的高度占用;
  • 触头工艺:黄铜基底确保导电效率(导电率约1.5×10^7 S/m),表面锡镀层提升焊接润湿性能(焊点更牢固,虚焊率低),同时防止黄铜氧化,延长接触可靠性(长期使用中接触电阻变化率<5%);
  • 塑料外壳:PA66材质兼具耐冲击(冲击强度≥60kJ/m²)、耐温特性,UL94V-0阻燃等级可有效抑制短路等异常工况下的燃烧风险,符合UL、CCC等安全认证要求,适配出口产品需求。

三、电气性能与可靠性表现

产品电气性能稳定,满足多数小功率应用的核心需求:

  • 电流承载能力:单针3A额定电流(降额使用至2A可提升10%可靠性),3针可支持多负载分路(如小型电机+传感器供电),实际使用中无明显发热(25℃环境下温升<15℃);
  • 接触电阻:黄铜+锡镀层的触头组合,初始接触电阻通常低于20mΩ(典型值),长期使用中因镀层防氧化,电阻变化率小,保证信号/电源传输稳定(无明显压降);
  • 绝缘性能:PA66外壳的绝缘电阻通常高于100MΩ(25℃、500V DC),相邻引脚间距符合安全标准,避免短路风险。

四、环境适应性与典型应用场景

宽温范围与阻燃特性使其适配多场景:

  • 环境耐受:-40℃~+105℃的工作温度覆盖北方户外设备(低温)、厨房电器(高温)等场景;PA66耐潮湿(吸水率<2%)、轻微酸碱,适合浴室、车间等潮湿环境;
  • 典型应用:
    1. 小型家电:豆浆机、榨汁机、加湿器的控制板连接(弯插节省空间,3A满足小电机电流);
    2. 仪器仪表:万用表、温湿度传感器模块的信号连接(宽温稳定,阻燃安全);
    3. 智能家居:智能开关、智能门锁的控制板连接(安装灵活,适配紧凑壳体);
    4. 小型工业控制:PLC扩展模块、小型继电器板的电源/信号连接(符合工业环境温湿度要求)。

五、安装与使用注意事项

为保证连接可靠性,需注意以下要点:

  • 焊接操作:弯插引脚焊接时,建议使用260℃±10℃的烙铁温度,焊接时间不超过3秒/针,避免高温导致塑料外壳变形(PA66变形温度约220℃);
  • 引脚对齐:安装前确保引脚与PCB焊盘完全对齐,避免虚焊(虚焊易导致接触电阻增大、发热故障);
  • 存储条件:产品应存储于常温(15℃~35℃)、干燥(相对湿度≤60%)环境,避免阳光直射,防止塑料老化;
  • 清洁要求:安装前避免触头沾油污、灰尘,可使用无水乙醇轻轻擦拭,保证焊接质量。

综上,CJT A2505WR-3P以通用间距、可靠性能与紧凑设计,成为小功率线对板连接的高性价比选择,适配多数民用与小型工业场景的连接需求,是替代同类型进口连接器的优选方案。

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
