KH-SMB-Z RF射频同轴连接器产品概述

一、产品核心定位与基础参数

KH-SMB-Z是金航标(Kinghelm)旗下小体积高频信号传输专用的板端射频同轴连接器,属于SMB(SubMiniature version B)射频系列标准件,以“紧凑结构+可靠连接”为核心优势,适配多种小型化电子设备的射频接口需求。

基础参数精准匹配目标场景:

  • 连接器类型:板端(垂直焊接于PCB板,节省空间)
  • 接口类型:内针(公端,适配SMB母端连接器)
  • 端口数量:单端口(1路射频信号传输)
  • 接口直径:3.7mm(符合SMB标准尺寸,兼容性强)
  • 板端高度:6mm(兼顾PCB安装空间与信号路径稳定性)
  • 射频系列:SMB(支持高频传输的小体积系列)
  • 封装形式:插件(DIP)(焊接固定,抗振动能力强)
  • 样式:正脚(引脚与接口轴线垂直,适配常规PCB孔位)

二、关键设计特点

  1. 小体积高密度适配
    3.7mm接口直径+6mm板高,可在PCB板上实现密集布局,满足工业控制、消费电子等设备的小型化设计需求(如无线AP、传感器节点的紧凑空间)。

  2. 可靠连接性能

    • 内针采用黄铜导体,表面镀锡(部分批次镀金),接触电阻≤20mΩ,信号损耗低;
    • 插件封装通过焊接固定,抗振动/冲击能力符合IEC 60068-2-6标准,适合工业现场等恶劣环境;
    • 绝缘材料采用PTFE(聚四氟乙烯),耐老化、耐化学腐蚀,长期使用无性能衰减。
  3. 高频传输性能
    支持1GHz~4GHz(实测覆盖至6GHz)高频范围,信号反射系数(VSWR)≤1.5:1(1GHz时),满足无线通信、物联网等场景的射频传输要求。

  4. 耐环境稳定性
    工作温度范围-40℃~+85℃,可适应低温户外、高温车间等极端工况。

三、典型应用场景

KH-SMB-Z的紧凑结构与可靠性能,使其广泛应用于以下领域:

  1. 工业控制与自动化
    PLC模块、工业传感器(温度/压力传感器无线端)、机器人控制系统的射频接口,满足工业现场抗振动、稳定传输需求。

  2. 通信设备
    小型基站(微基站)、无线AP、蓝牙/WiFi模块的板端射频连接,适配设备小型化趋势。

  3. 消费电子
    智能家居(智能门锁、安防摄像头)、无人机飞控模块、便携式医疗设备(小型监护仪)的射频信号传输。

  4. 物联网终端
    LPWAN终端、智能穿戴(智能手表蓝牙模块)的射频接口,实现小体积下的稳定连接。

四、品牌与品质保障

金航标(Kinghelm)作为国内专业射频连接器厂商,KH-SMB-Z具备以下品质优势:

  • 标准合规:符合RoHS环保指令、CE认证,满足国际市场准入要求;
  • 严格测试:每批次经过高频性能测试(VSWR、插入损耗)、插拔寿命测试(≥500次)、环境可靠性测试(高低温、湿度、振动);
  • 售后支持:提供选型咨询、安装指导,常规产品质保1年,批量客户可定制适配方案。

五、选型与安装注意事项

  1. 选型确认

    • 对端需搭配SMB母端连接器(如Kinghelm KH-SMB-K系列);
    • PCB板孔距需匹配常规DIP封装(建议2.54mm左右)。
  2. 安装要点

    • 焊接温度控制在260℃~300℃,焊接时间≤3秒,避免损伤绝缘材料;
    • 插拔时垂直用力,禁止斜插/旋转,防止内针变形。
  3. 维护建议
    定期用无水酒精清洁接口灰尘,避免氧化影响接触;线缆弯曲半径≥5倍直径,防止过度弯折。

KH-SMB-Z凭借“小体积、高可靠、易安装”的特点,成为小型化电子设备射频连接的优选方案,适配多行业的高频信号传输需求。

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
