JST B3B-PH-K-S 连接器产品概述

一、产品核心身份与定位

JST B3B-PH-K-S是一款单排3位公形引脚通孔连接器,属于JST PH系列,主打板至电缆/导线的电气连接场景。该产品以紧凑间距、可靠锁合和防护设计为核心,适配小型化电子设备的布线需求,是工业控制、消费电子等领域的常用基础连接器之一。

二、基础规格参数详解

该连接器的关键参数可分为电气、机械、材料三大类,具体如下:

(1)电气性能参数

  • 额定电流:2A(单引脚),满足小功率信号与电力传输需求;
  • 额定电压:100V(AC/DC),符合低压电气系统规范;
  • 工作温度范围:-25℃ ~ 85℃,适应常见室内外环境温度变化;
  • 阻燃等级:UL94 V-0,具备优异防火性能,降低安全隐患。

(2)机械结构参数

  • 间距:2.00mm(0.079"),紧凑设计节省PCB与布线空间;
  • 针位数:3位,单排布局,所有引脚均加载(无空针);
  • 引脚类型:公形方形触头,适配母端连接器的接触需求;
  • 安装方式:通孔(Through Hole),兼容传统PCB焊接工艺;
  • 紧固类型:销锁设计,与母端配接时可实现可靠锁合,防振动松脱;
  • 接触长度:配接端3.30mm,柱端3.40mm,总长度8.45mm,确保连接深度与电气稳定性;
  • 绝缘高度:6.00mm,平衡绝缘防护与安装空间。

(3)材料与表面处理

  • 触头材料:黄铜,兼具良好导电性与机械强度;
  • 触头表面处理:锡-铅镀层,提升耐腐蚀性与焊接性能;
  • 绝缘材料:聚酰胺(PA66,尼龙6/6),天然色,绝缘性与耐冲击性优异。

三、设计与性能优势

  1. 紧凑空间适配:2.00mm间距是小型化设备的理想选择,可有效减少PCB布线密度,降低设备体积;
  2. 可靠连接保障:销锁紧固结构+压接/焊接双端接方式,既支持电缆压接(需专用工具),也可通过焊接固定于PCB,双重避免振动或外力导致的接触不良;
  3. 防护与抗干扰:4墙遮蔽护罩设计,减少外部电磁干扰(EMI)对信号的影响,同时保护触头免受灰尘、异物侵入;
  4. 安全与耐用性:UL94 V-0阻燃等级符合全球安全规范,PA66绝缘材料耐温耐老化,黄铜触头镀层提升使用寿命;
  5. 安装便捷性:通孔安装无需特殊工装,传统焊接设备即可操作,适合批量生产。

四、典型应用场景

JST B3B-PH-K-S因体积小、性能稳定,广泛应用于以下领域:

  • 小型工业控制:传感器模块、微型PLC接口、小型电机驱动;
  • 消费电子:智能穿戴(手环、手表)配件、小型家电(加湿器、智能插座)内部连接;
  • 通信设备:小型基站配件、数据传输模块、光纤收发器接口;
  • 便携式设备:手持测试仪、医疗监护仪配件、无人机小型组件。

五、选型与使用注意事项

  1. 配接匹配:需与JST PH系列母形连接器(如B3P-PH-K-S)配接,确保间距、针位数一致,避免尺寸不匹配导致连接失效;
  2. 端接操作:压接需用JST专用压接钳(PH系列),焊接温度控制在260℃以内(停留≤3秒),防止绝缘材料熔化;
  3. 环境限制:避免在腐蚀性气体(硫化氢、氯气)环境中使用,长期暴露会降低触头镀层性能;
  4. 安装要求:通孔安装时对齐PCB焊盘,确保引脚完全插入,焊接后清理残留助焊剂,提升可靠性。

该产品作为JST PH系列的基础型号,以高性价比与稳定性能,成为众多小型电子设备的首选连接器之一,满足不同场景下的板线连接需求。

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
