CJT A1251WR-S-4P-LCP 1.25mm卧贴连接器产品概述

一、产品核心定位与适用场景

CJT A1251WR-S-4P-LCP是一款1.25mm间距单排卧贴连接器,专为小型化、高密度电子设备的信号传输与小电流供电设计。其紧凑结构与稳定性能,可适配消费电子、汽车电子、工业控制等领域对微型连接器的需求,尤其适合空间受限的PCB布局场景(如智能穿戴、小型传感器模块)。

二、基础参数与结构设计

1. 机械规格

  • 引脚结构:单排4针(1×4P),总PIN数4P;
  • 间距与安装:引脚间距1.25mm,采用卧贴(SMD)安装,无需通孔焊接,兼容自动化贴装工艺;
  • 外壳材质:液晶聚合物(LCP),尺寸精度高、长期使用无变形,阻燃等级达UL94V-0(遇明火不易燃烧)。

2. 电气性能

  • 额定参数:单针额定电流1A,额定电压125V AC/DC;
  • 温宽范围:工作温度-40℃~+105℃,覆盖高低温环境(如车载、户外传感器);
  • 触头特性:磷铜基材(弹性好、导电稳定)+ 锡镀层(可焊性佳、防氧化),接触电阻低且波动小。

三、关键性能优势

1. 小型化高密度适配

1.25mm间距是当前主流微型连接器规格,单排4针设计可在有限PCB面积内实现多信号/电源传输,完美适配智能手表、TWS耳机等便携设备的紧凑布局。

2. 可靠接触与焊接性能

磷铜触头的弹性确保插拔时紧密贴合,锡镀层不仅提升可焊性(适配无铅焊接工艺),还能有效防止触头氧化,长期使用接触电阻稳定(≤20mΩ)。

3. 耐环境适应性强

LCP塑料耐高低温、低吸水性(吸水率<0.1%),在潮湿或高温环境下仍能保持结构稳定;宽温范围覆盖了大部分电子设备的使用场景(如车载-40℃低温、工业+105℃高温)。

4. 生产效率提升

卧贴SMD安装方式兼容自动化贴片机,无需手工焊接通孔,可大幅提高批量生产效率,降低人工成本与焊接不良率。

5. 安全合规

符合RoHS环保标准(无铅、无有害物质)与UL94V-0阻燃等级,满足全球电子设备的安全与环保要求,便于产品出口。

四、典型应用领域

  1. 消费电子:智能手机、智能手表、蓝牙耳机、TWS充电盒的内部信号连接;
  2. 汽车电子:车载传感器(胎压、温度)、中控小模块、车载摄像头的辅助连接;
  3. 工业控制:小型PLC、物联网传感器节点、工业机器人末端执行器的信号传输;
  4. 智能家居:智能门锁、智能音箱、小型家电(加湿器、净化器)的控制模块连接。

五、品牌与质量保障

CJT(长江连接器)是国内连接器行业知名品牌,拥有10+年专业设计生产经验,产品通过ISO9001质量管理体系认证。A1251WR-S-4P-LCP系列出厂前经过插拔寿命测试(≥100次)、电气性能测试(接触电阻/绝缘电阻),批量生产一致性好,可满足客户长期稳定供货需求。

该产品凭借紧凑尺寸、可靠性能与合规性,成为小型电子设备信号连接的高性价比选择。

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
