KH-RJ45-58-8P8C以太网连接器产品概述

KH-RJ45-58-8P8C是金航标(Kinghelm)推出的一款单端口RJ45以太网插座,采用弯插安装、插件封装设计,具备金属屏蔽层、无LED指示等核心特征,适配10/100/1000Mbps以太网通信需求,广泛应用于工业、消费电子、网络通信等领域。

一、产品定位与核心特征

该产品定位为紧凑式单路以太网接口,核心特征可清晰归纳为:

  • 接口类型:标准8P8C RJ45插座(兼容RJ45水晶头);
  • 端口数量:1个独立以太网端口;
  • 安装方式:弯插(PCB垂直板面安装,节省水平空间);
  • 屏蔽设计:带金属屏蔽壳(抑制电磁干扰);
  • 指示功能:无LED指示灯(简化电路,降低功耗);
  • 封装形式:插件式(引脚焊接固定,连接可靠);
  • 品牌归属:Kinghelm(金航标),国内专业连接器厂商,产品符合RoHS环保标准。

二、关键参数解析

1. 接口与传输性能

采用8P8C(8针8槽)结构,完全符合RJ45国际标准,支持10Base-T、100Base-TX、1000Base-T等以太网协议,可实现10/100/1000Mbps速率的稳定传输。单端口设计满足单路设备的网络连接需求,避免冗余端口占用空间。

2. 安装与封装特点

  • 弯插安装:引脚与接口呈90°垂直,安装后连接器与PCB板垂直,可有效节省PCB的水平布局空间,适合紧凑设计的设备(如小型交换机、工业控制器);
  • 插件封装:通过引脚焊接固定于PCB,焊接牢固性优于贴片封装,抗振动、抗冲击性能更好,适合长期运行的工业场景。

3. 屏蔽与抗干扰能力

内置金属屏蔽壳(通常为锌合金或铜合金),并配备接地引脚,可有效隔离外部电磁干扰(EMI) 和内部信号对外辐射,提升信号传输的稳定性,尤其适合工业现场、高干扰环境(如变频器附近、电力设备旁)。

4. 环境与可靠性参数

  • 工作温度:-40℃~85℃(工业级宽温范围);
  • 存储温度:-55℃~100℃;
  • 额定插拔次数:≥1000次;
  • 接触电阻:≤20mΩ(低接触电阻保障信号完整性);
  • 绝缘电阻:≥1000MΩ(500V DC)。

三、设计优势与应用价值

1. 空间优化:弯插结构节省布局

弯插设计使连接器安装后不占用PCB的水平面积,适合小型化设备(如便携式路由器、智能网关)的紧凑布局,避免因端口占用导致的PCB尺寸增加。

2. 抗干扰:屏蔽层保障稳定传输

金属屏蔽壳+接地设计可有效抑制电磁干扰,解决工业环境中常见的“信号串扰、传输丢包”问题,提升设备在复杂电磁环境下的通信可靠性。

3. 成本控制:无LED简化设计

取消LED指示灯可简化电路设计(无需额外驱动电路),降低BOM成本,适合对“状态指示无强制要求”的场景(如部分工业传感器、隐蔽式网络设备)。

4. 可靠性:插件封装抗应力

插件式引脚焊接牢固,可承受一定的机械振动(如工业设备的运行振动),相比贴片封装更适合需要高可靠性的场景。

四、典型应用场景

KH-RJ45-58-8P8C的应用覆盖多领域,核心场景包括:

  1. 工业自动化:PLC可编程控制器、HMI人机界面、工业传感器节点的以太网通信接口;
  2. 网络通信设备:小型交换机、路由器、无线AP的RJ45端口;
  3. 消费电子:智能电视、机顶盒、网络摄像头的有线网络连接;
  4. 安防系统:网络摄像机、NVR网络硬盘录像机的有线接口;
  5. 车载电子:车载信息娱乐系统(IVI)的以太网连接(部分商用车场景)。

五、安装与使用注意事项

  1. 焊接规范:引脚焊接温度控制在260℃以内,单次焊接时间不超过3秒,避免高温损坏塑料外壳;
  2. 屏蔽接地:屏蔽壳需通过接地引脚或PCB接地层可靠接地,否则屏蔽效果失效;
  3. 插拔操作:插拔RJ45水晶头时需垂直对准接口,避免斜向用力导致引脚变形;
  4. 环境防护:避免在潮湿、腐蚀性气体环境中使用,如需户外应用需额外做防护处理;
  5. 静电防护:生产、焊接过程中需佩戴ESD手环,避免静电损坏接触件。

该产品凭借紧凑设计、抗干扰能力和高可靠性,成为多领域以太网接口的优选方案,可满足不同场景下的网络连接需求。

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.
