金航标KH-2.54FH-1X8P-H8.5单排方孔直插排母产品概述

一、产品核心定位与基本属性

金航标KH-2.54FH-1X8P-H8.5是一款2.54mm间距单排方孔直插排母,属于金航标(kinghelm)2.54mm系列插件连接器的核心型号。该产品针对中小功率信号/电源连接需求设计,以“高接触稳定性、宽温适应性、行业通用兼容”为核心特点,适配工业控制、车载、消费电子等多领域设备的PCB板间连接。

其基本属性清晰:1x8P单排结构、方孔插孔、直插式安装、塑高8.5mm,额定电流3A,工作温度覆盖-40℃至+105℃,完全符合电子连接器行业标准规范。

二、关键参数深度解析

1. 间距与孔位:通用兼容+精准适配

  • 2.54mm标准间距:又称“0.1英寸”,是电子行业最通用的连接器间距,与绝大多数PCB板通孔布局兼容,无需额外调整设计即可替换同类产品;
  • 1x8P单排结构:满足8路独立信号/电源的并行传输需求,适合小型模块、传感器接口等场景的紧凑设计。

2. 孔型:方孔优于圆孔的接触性能

采用方孔插孔(区别于常规圆孔),核心优势:

  • 与方针插针的接触面积比圆孔大15%以上,初始接触电阻≤15mΩ(插拔500次后≤20mΩ);
  • 插拔时配合间隙更小,减少晃动导致的接触不良;
  • 方孔机械强度更高,长期插拔不易变形,延长使用寿命。

3. 电流与温度:宽温适应+中小功率覆盖

  • 额定电流3A:单孔在AC/DC 250V额定电压下可稳定传输3A电流,适配12V电源下36W功率的设备(如小家电、小型传感器);
  • -40℃~+105℃宽温:覆盖工业环境(-20℃+85℃)、车载环境(-40℃+85℃)及部分高温场景,无需额外散热设计。

4. 安装与尺寸:直插牢固+空间优化

  • 直插式安装:配合PCB板通孔焊接,焊接后连接强度≥10N(拉力测试),抗振动性能优异;
  • 8.5mm塑高:平衡“安装空间”与“插拔便利性”——既不占用过多PCB板上方空间,又保证插针插入的操作手感。

三、结构设计与工艺优势

1. 塑壳材料:耐高温阻燃

采用UL94V-0级PA66工程塑料,具备:

  • 长期工作温度105℃,短期耐波峰焊温度260℃(≤3s);
  • 阻燃性符合国际安全标准,降低设备起火风险;
  • 抗冲击、抗老化,使用寿命可达10年以上。

2. 插孔工艺:精密冲压+防氧化

  • 方孔采用精密冲压成型,孔径公差±0.02mm,与插针紧密配合;
  • 插孔表面镀锡处理,提高导电性能,长期使用无氧化、接触电阻增大问题。

3. 焊接兼容性:常规工艺适配

适配PCB板通孔(孔径2.6mm~2.8mm),支持波峰焊、手工焊两种常规工艺,无需特殊工具即可实现可靠连接。

四、电气性能与可靠性验证

该产品通过多项行业标准测试,核心性能:

  • 绝缘电阻:≥1000MΩ(100V DC下);
  • 耐电压:AC 500V(50Hz,1min)无击穿、飞弧;
  • 插拔寿命:≥500次(符合IEC 60947-5-2标准);
  • 可靠性测试:温度循环(-40℃+105℃,500次)、振动(10Hz2000Hz,10g,2h)后性能无衰减。

五、典型应用场景

因宽温、高可靠及通用兼容,该产品广泛应用于:

  • 工业控制:PLC模块、传感器接口、电机驱动板;
  • 车载电子:车载显示屏、控制器、倒车雷达模块;
  • 消费电子:小家电控制板(电饭煲、豆浆机)、智能音箱接口;
  • 通信设备:小型路由器、交换机接口;
  • 仪器仪表:测试仪器、医疗监护仪信号接口。

六、选型与安装注意事项

  1. 插针匹配:优先搭配2.54mm间距方针插针(如金航标KH-2.54FZ系列),圆针需注意直径≤1.0mm;
  2. 焊接控制:波峰焊温度250℃~260℃(≤3s),手工焊烙铁温度≤300℃(避免烫伤塑壳);
  3. 电流分配:单孔最大3A,大电流需并联孔位(如5A需2孔并联);
  4. 空间预留:PCB板上方需预留≥10mm空间(塑高+插拔操作)。

总结

金航标KH-2.54FH-1X8P-H8.5是一款高性价比的方孔直插排母,以“标准间距、稳定接触、宽温适应”为核心优势,兼容行业通用设计,适配多领域应用。经严格可靠性测试,可满足工业级、车载级等不同等级的使用需求,是中小功率设备PCB板间连接的可靠选择。

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.
