PJ-320D TT 3.5mm SMD音频连接器产品概述

PJ-320D TT是首韩(SHOU HAN)品牌推出的一款小型化3.5mm音频连接器,采用表面贴装(SMD)封装设计,专为消费电子、便携设备的音频信号传输场景优化,兼具通用性、可靠性与生产适配性。以下从核心规格、性能特点、应用场景等维度展开详细说明。

一、产品基本定位与核心规格

PJ-320D TT定位于中低端消费电子音频接口,核心规格覆盖音频传输的基础需求,具体如下:

  • 连接器类型:3.5mm标准耳机座(兼容3极/4极音频插头,适配单声道/立体声传输)
  • 封装形式:SMD贴片(无引脚设计,适合自动化贴片生产)
  • 触头镀层:高纯度银(99.9%)
  • 电气额定值:额定电流500mA(AC/DC通用)、额定电压30V(AC/DC)
  • 环境温度:工作温度-30℃~+70℃(满足日常高低温场景,如冬季户外、夏季车内)、存储温度-40℃~+85℃(行业常规冗余设计)

二、关键性能参数解析

1. 电气性能:低损耗、稳定传输

  • 接触电阻:≤50mΩ(银镀层低阻抗特性,减少音频信号传输损耗,保障音质清晰)
  • 绝缘电阻:≥100MΩ(触头间绝缘良好,避免信号串扰)
  • 耐电压:AC 500V(50Hz)/1min(无击穿、无飞弧,满足基本电气安全要求)

2. 机械性能:适配小型化与高插拔需求

  • 插拔力:插入力≤5N、拔出力≥1N(手感适中,避免插头松动或插拔困难)
  • 插拔寿命:≥5000次(满足常规使用周期,如手机耳机接口3年以上插拔需求)
  • 尺寸:典型值10mm×6mm×5mm(紧凑设计,适配手机、平板等小型设备内部空间)

3. 环境适应性:覆盖主流使用场景

  • 耐温性:工作温度区间覆盖-30℃(冬季低温)至+70℃(夏季高温环境),无性能衰减
  • 耐湿:相对湿度≤90%RH(40℃),避免潮湿环境导致触头氧化

三、结构设计与工艺特点

1. SMD封装:适配自动化生产

采用无引脚贴片设计,可直接通过回流焊工艺焊接到PCB板,无需额外插件工序,大幅提升电子设备生产效率,降低人工成本。

2. 触头防护:防尘防氧化

内置防尘盖结构(可选),防止灰尘、碎屑进入触头区域,延长使用寿命;银镀层表面经过钝化处理,抗氧化能力优于普通镀锡触头,长期使用后接触电阻无明显上升。

3. 壳体材料:耐高温抗冲击

壳体采用耐高温ABS+PC合金材料,可承受回流焊峰值温度(250℃~260℃),无变形、开裂风险;同时具备一定抗冲击能力,适配便携设备的跌落场景。

四、典型应用场景

PJ-320D TT因尺寸紧凑、性能稳定,广泛应用于以下领域:

  1. 便携式电子设备:智能手机、平板电脑、智能手表的音频输出/输入接口(部分机型保留3.5mm接口)
  2. 音频外设:蓝牙耳机充电盒、便携蓝牙音箱、有线耳机的母座
  3. 小型电子设备:MP3/MP4播放器、电子词典、游戏机(如Switch Lite)的音频接口
  4. 车载辅助系统:部分经济型车载音响的3.5mm辅助音频输入接口(适配手机、U盘音频传输)

五、安装与可靠性说明

1. 安装注意事项

  • 焊接工艺:采用回流焊,温度曲线需符合IPC标准(预热150℃~180℃,峰值255℃±5℃,保温时间≤30s)
  • 存储条件:未焊接产品需存放在干燥环境(湿度≤60%RH),避免阳光直射
  • 安装方向:需按PCB板丝印方向焊接,避免触头错位影响插拔

2. 可靠性测试验证

产品出厂前需通过多项可靠性测试:

  • 高低温循环测试:-30℃~+70℃,50个循环,性能无衰减
  • 振动测试:10Hz~2000Hz,加速度1g,持续2h,无接触不良
  • 盐雾测试:5%NaCl溶液,48h,触头无腐蚀、接触电阻变化≤10%

六、品牌与品质保障

首韩(SHOU HAN)作为国内专注音频连接器的制造商,产品通过ISO9001质量管理体系认证,PJ-320D TT具备以下品质优势:

  • 每批次产品100%检测电气性能(接触电阻、绝缘电阻)与机械性能(插拔力)
  • 提供12个月质保服务,技术支持响应时间≤24h
  • 原材料均来自行业认证供应商,确保批次稳定性

综上,PJ-320D TT以高通用性、低生产成本、稳定性能为核心优势,是消费电子领域3.5mm音频接口的高性价比选择。

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
