HRS DF1B-7ES-2.5RC 线对板/线对线胶壳产品概述

DF1B-7ES-2.5RC是日本广濑电机(HRS)推出的一款小型化连接胶壳,专为紧凑空间内的稳定信号与电力传输设计,以下从多维度详细说明其核心特性与应用场景。

一、基础参数与封装标识

该胶壳的核心参数完全匹配小型设备的连接需求:

  • 连接规格:1排7Pin(1×7P)单排布局,针脚间距2.5mm,符合行业标准间距设计,适配多数小型PCB尺寸;
  • 结构特征:不带锁扣设计简化插拔操作,带翅结构增强PCB固定强度;
  • 外观与包装:主体为白色工程塑料,封装型号明确标注为HRS DF1B-7ES-2.5RC,包装规格为17盘×96个/盘,适合中小批量生产;
  • 应用类型:属于线对板(胶壳端接PCB)或线对线(胶壳端接导线)通用型胶壳,兼容性强。

二、结构设计核心优势

  1. 紧凑布局节省空间:1×7P单排设计搭配2.5mm间距,相比多排结构节省约30%的PCB占用面积,适合智能家居、小型家电等对空间敏感的设备;
  2. 带翅结构提升可靠性:胶壳底部带定位翅,安装时嵌入PCB预留槽位,配合焊接后可承受≥5N抗拉力,防止插拔或设备振动时胶壳脱落;
  3. 无锁扣简化操作:取消锁扣后无需额外解锁步骤,适合快速装配/维护场景(如小型电子设备模块更换),同时降低锁扣磨损失效风险;
  4. 耐候性材质:采用HRS定制的PA66工程塑料,兼具耐冲击、耐老化特性,长期使用无脆化问题。

三、电气性能指标(基于HRS DF1B系列标准)

作为HRS成熟系列产品,其电气性能稳定可靠:

  • 额定参数:额定电压250V AC/DC,额定电流2A/针(连续负载),满足小型设备电力与信号传输需求;
  • 接触可靠性:初始接触电阻≤20mΩ,经50次插拔后仍保持≤50mΩ,确保信号无衰减;
  • 绝缘与耐电压:绝缘电阻≥1000MΩ(500V DC),耐电压1000V AC/1分钟(无击穿),符合工业级安全标准;
  • EMI防护:胶壳边缘圆角设计与紧密配合结构,减少电磁干扰泄露,适配对EMC要求较高的通信设备。

四、机械性能与环境适应性

  1. 插拔寿命:支持≥50次插拔循环,远超行业同类产品30次的平均水平,适合频繁维护场景;
  2. 温度范围:工作温度-40℃至+85℃,存储温度-55℃至+125℃,可适应工业环境温控波动与车载低温场景;
  3. 抗振动性能:配合带翅固定与端子弹性接触设计,可承受10G(10-2000Hz)振动测试,防止连接松动。

五、典型应用场景

DF1B-7ES-2.5RC的特性使其适配以下场景:

  • 消费电子:小型电饭煲、智能音箱、电动牙刷等设备的内部PCB与导线连接;
  • 工业控制:小型PLC模块、温度/湿度传感器节点的信号传输;
  • 车载配件:车载充电器、仪表盘辅助模块的低功耗连接(非安全关键部位);
  • 通信设备:小型路由器、机顶盒的内部模块间连接。

六、配套与选型建议

  1. 配套端子:需匹配HRS DF1B系列端子,推荐DF1B-2824SC(适配28AWG导线),确保端子与胶壳紧密配合;
  2. 替代型号:若需带锁扣设计,可选DF1B-7ES-2.5R;若PIN数不同,可选择3P、5P等同系列规格;
  3. 安装注意:焊接温度≤260℃(焊接时间≤3秒),避免高温损坏胶壳材质。

总结:DF1B-7ES-2.5RC凭借紧凑布局、可靠固定、快速插拔等特性,成为小型电子设备内部连接的高性价比选择,同时延续了HRS产品的稳定性能与环境适应性。

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
