PJ-342B-TX-SMT 3.5mm音频连接器产品概述

PJ-342B-TX-SMT是中国星坤(XKB Connectivity)推出的一款6脚4级3.5mm贴片式音频连接器,专为消费电子、便携式设备及车载音频系统设计,兼顾小型化、可靠性与生产效率,适配高密度PCB布局需求。

一、产品核心定位与应用场景

该连接器聚焦音频信号传输与输入输出集成,4级结构支持“音频输出+麦克风输入+接地”多通道集成(对应TRRS接口类型),解决单接口同时满足耳机听声与语音输入的需求。其贴片封装特性,使其成为小型化电子设备的理想选择,典型应用覆盖:

  • 智能手机、平板电脑的音频二合一接口;
  • 轻薄笔记本电脑的耳机/麦克风复合接口;
  • 便携式蓝牙音箱、MP3/MP4播放器的音频输入/输出接口;
  • 车载多媒体系统的音频辅助输入接口;
  • 小型智能家居设备(如智能音箱)的音频扩展接口。

二、基础参数与性能规格

PJ-342B-TX-SMT的核心参数严格匹配消费电子应用的可靠性要求,具体如下:

参数项 规格值 连接器类型 3.5mm音频座 引脚/级数 6脚4级(TRRS) 额定电流 500mA(DC) 额定电压 30V(DC/AC) 工作温度范围 -20℃~+70℃ 外形尺寸(长×宽×高) 14mm×6.4mm×4.5mm 封装形式 SMD(贴片式) 接触件镀层 镀金(铜套+鱼叉脚)

注:参数符合常规消费电子设备的供电与信号传输需求,避免过载风险。

三、结构设计与工艺特点

该连接器的结构与工艺设计围绕可靠性、抗磨损、小型化三大核心展开:

  1. 4级多通道集成:6脚设计实现“左声道、右声道、麦克风、接地”4通道独立传输,避免信号串扰,适配带麦克风的耳机使用;
  2. 镀金接触件:铜套与鱼叉脚均采用镀金工艺,镀层厚度满足抗氧化、低接触电阻(<50mΩ)要求,支持频繁插拔(≥5000次)仍保持稳定传输;
  3. 鱼叉脚固定结构:端子采用鱼叉式设计,焊接时与PCB焊盘紧密结合,增强机械强度,防止插拔过程中端子脱落;
  4. 紧凑外形尺寸:14×6.4×4.5mm的小体积,适配智能手机、平板等内部空间紧凑的设备,不影响整体布局。

四、封装与安装方式

PJ-342B-TX-SMT采用SMD贴片封装,适配自动化表面贴装技术(SMT),具有以下优势:

  • 无需PCB钻孔,节省PCB空间与制造成本;
  • 自动化贴装效率高,适合大规模量产;
  • 焊接后无通孔残留,提升设备内部整洁度;
  • 安装时需注意焊接温度(常规SMT回流焊温度曲线,峰值温度≤260℃),避免损坏连接器。

五、品牌与品质保障

该产品由中国星坤(XKB Connectivity)生产,星坤作为专业连接器制造商,产品符合以下品质要求:

  • 符合RoHS环保标准,无有害物质(铅、镉等);
  • 经过插拔寿命、高低温循环、振动测试等可靠性验证,满足消费电子行业标准;
  • 镀金工艺符合行业通用可靠性规范,接触件长期使用无氧化失效风险。

六、典型应用场景的适配性

以智能手机为例,PJ-342B-TX-SMT的4级结构可同时支持耳机听音乐与语音通话,贴片封装节省内部空间;对于笔记本电脑,其小体积适配轻薄机型的窄边框设计,同时满足音频输出与麦克风输入的复合需求。在车载场景中,其宽温度范围(-20℃~+70℃)可适应车内高低温环境,稳定传输音频信号。

综上,PJ-342B-TX-SMT凭借小型化、多通道集成、高可靠性的特点,成为消费电子与便携式设备音频接口的优选方案,适配自动化生产与高密度布局需求。

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
