A1251WR-S-8P-LCP线对板针座产品概述

A1251WR-S-8P-LCP是长江连接器(CJT)推出的1.25mm间距单排卧贴式线对板针座,专为小型化电子设备的导线与PCB可靠连接设计,核心参数与材料特性适配多场景应用需求。

一、产品基本定位与核心参数

该针座属于线对板连接组件范畴,核心功能是实现导线端子与PCB的电气导通及机械固定,核心参数明确:

  • 结构设计:1×8P单排插针(无排数冗余,适配8路信号/电源传输);
  • 封装规格:卧贴(SMD)封装,引脚间距1.25mm(行业窄间距设计,显著节省PCB空间);
  • 基本计数:总PIN数8,每排8针,排数1;
  • 品牌与料号:长江连接器(CJT)原厂出品,料号后缀“LCP”明确塑料主体材质为液晶聚合物。

二、关键材料与工艺特性

产品性能依赖材料选型与工艺优化,核心材料特性如下:

2.1 触头系统(电气核心)

  • 基材:磷铜(Cu-P合金)—— 兼具优异导电性(电导率≈40%IACS)、弹性(插拔力稳定)与耐腐蚀性(避免环境因素导致接触失效);
  • 镀层:表面镀锡(Sn)—— 锡镀层成本可控,焊接润湿性优异(适配SMD回流焊工艺),且在常温下不易氧化,保证长期接触可靠性。

2.2 塑料主体(结构支撑)

  • 材质:LCP(液晶聚合物)—— 具备高尺寸稳定性(回流焊高温下变形量≤0.1mm)、耐高温性(短期耐温≥280℃,适配回流焊峰值温度);
  • 阻燃性能:UL94V-0等级(垂直燃烧无滴落,符合电子设备防火安全标准);
  • 机械强度:塑料主体与插针采用“过盈配合+注塑包封”工艺,结合牢固,避免插拔过程中插针脱落。

三、电气性能参数

产品电气性能满足常规低压电子设备需求,关键参数如下:

  • 额定电流:1A/单PIN(注:实际应用需根据散热条件降额,多PIN同时负载时需避免总电流过载);
  • 额定电压:125V AC/DC(覆盖消费电子、工业控制等低压场景的常规电压范围);
  • 接触电阻:典型值≤20mΩ(磷铜基材与锡镀层的协同作用,保证信号传输无明显损耗);
  • 绝缘电阻:常态(25℃/60%RH)下≥1000MΩ(LCP材料绝缘性能优异,避免引脚间短路风险)。

四、机械与环境适应性

产品适配多工况环境,机械与环境性能稳定:

  • 插拔寿命:≥500次(单排结构插拔力均匀,触头弹性衰减符合行业标准);
  • 工作温度范围:-40℃~+105℃(宽温设计,适配工业控制、汽车电子等高低温场景);
  • 环境耐受性:耐潮湿(盐雾试验48h无异常)、耐弱酸碱腐蚀(适配户外或恶劣工况);
  • 安装适配:SMD引脚符合IPC-A-610标准,可通过标准回流焊工艺焊接,无需额外工装。

五、典型应用场景

因窄间距、宽温、高可靠性特性,该针座广泛应用于:

  • 消费电子:智能手机、平板电脑、智能手表的内部信号/电源连接(小型化需求);
  • 工业控制:小型PLC、传感器模块、物联网网关的接口连接;
  • 汽车电子:车载仪表盘、胎压监测传感器、车载充电器的内部连接(宽温适配);
  • 智能家居:智能音箱、智能门锁、安防摄像头的内部布线;
  • 医疗设备:小型监护仪、血糖仪的内部信号连接(LCP阻燃与宽温符合医疗设备安全标准)。

六、安装与选型注意事项

为保证产品可靠性,需注意以下要点:

  1. 焊接工艺:仅适配回流焊(禁止手工焊,避免温度不均导致塑料变形或引脚虚焊),焊接温度曲线需满足“峰值温度≤260℃,恒温时间≤10s”;
  2. 匹配要求:需与CJT对应1.25mm间距的线端连接器(如端子线)配合使用,避免引脚错位导致接触不良;
  3. 降额使用:单PIN额定电流1A为极限值,若传输持续大电流,需增加PCB散热铜箔或采用多PIN并联;
  4. 替代验证:若需替代,需确认间距(1.25mm)、PIN数(8P)、封装(SMD卧贴)、材料(LCP) 完全一致,避免性能差异。

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
