KH-DC-007B-2.1G DC电源插座产品概述

KH-DC-007B-2.1G是金航标(kinghelm)推出的一款弯插式DC电源插座,针对需要稳定直流供电的电子设备设计,兼顾性能、安装灵活性与可靠性,广泛适配消费电子、工业控制、安防等多领域场景。

一、产品核心定位与典型应用场景

这款插座的核心定位是小电流直流供电的紧凑型解决方案,重点解决设备内部空间有限、供电稳定性要求高的问题。常见应用包括:

  1. 家用电子设备:路由器、机顶盒、智能音箱等小型家电,这些设备需持续稳定供电,3A额定电流完全满足其功率需求(比如12V/2A的路由器供电);
  2. 工业控制模块:小型PLC、传感器节点等,弯插结构适配模块内部紧凑的PCB布局,避免直插占用垂直空间;
  3. 安防监控设备:户外小型摄像头(工作温度范围覆盖-30℃~+70℃,适应南北温差),确保低温环境下供电不中断;
  4. 便携式设备:移动电源、手持终端等,插件封装焊接可靠,耐插拔(常规插拔次数≥5000次),适合频繁插拔的使用场景。

二、关键性能参数解析

KH-DC-007B-2.1G的参数设计贴合实际使用需求,核心参数如下:

  • 额定电流3A:覆盖绝大多数小型直流设备的供电需求(比如12V/3A的LED显示屏、24V/2A的小型电机驱动),持续工作时无明显发热;
  • 额定电压50V:兼容12V、24V、48V等常见直流电压等级,无需担心电压过高损坏插座;
  • 弯插+插件封装:弯插结构让插座与PCB板呈90°角,节省设备内部垂直空间;插件封装焊接面积大,电流承载能力优于贴片封装,适合大电流场景;
  • 工作温度-30℃~+70℃:适应低温(北方冬季户外)和常温环境,不会因温度变化导致接触电阻增大或外壳变形。

三、结构设计与安装特性

  1. 导电接触件设计:采用优质磷铜材质(部分接触点镀金),确保低接触电阻(≤20mΩ),减少电流损耗,同时耐氧化、耐腐蚀,延长使用寿命;
  2. 绝缘外壳材质:选用耐高温工程塑料(如PA66),符合UL94 V-0阻燃等级,避免因短路或过载引发火灾;
  3. 安装便捷性:弯插式设计可直接焊接在PCB板侧面,无需额外的空间调整;插件引脚长度适中,焊接时不易出现虚焊,提升生产效率。

四、环境适应性与可靠性验证

这款插座经过多项可靠性测试,确保在不同场景下稳定运行:

  • 低温测试:在-30℃环境下放置24小时后,插拔50次仍保持电气性能正常;
  • 湿热测试:在60℃、95%RH环境下放置48小时,绝缘电阻仍≥100MΩ(符合安全标准);
  • 插拔寿命:连续插拔5000次后,接触电阻变化≤10%,无松动或变形;
  • 耐电压测试:承受500VAC(50Hz)电压1分钟,无击穿或闪络现象。

五、品牌与品质保障

金航标(kinghelm)作为国内连接器领域的老牌厂商,KH-DC-007B-2.1G通过以下品质保障:

  • 环保认证:符合RoHS 2.0、REACH等国际环保标准,无有害物质;
  • 质量管理体系:通过ISO9001:2015认证,生产过程严格管控;
  • 售后支持:提供1年质保,针对批量采购客户可定制参数(如引脚长度、外壳颜色)。

这款插座以“小体积、高可靠、易安装”为核心优势,能快速适配各类直流供电设备的需求,是电子设计中稳定供电的优选方案。

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
