金航标KH-2.54FH-1X4P-H8.5 单排方孔直插连接器产品概述

一、产品定位与核心价值

KH-2.54FH-1X4P-H8.5是金航标(Kinghelm)针对小型化设备信号/小功率传输需求推出的2.54mm间距单排方孔直插连接器,兼顾可靠性与安装效率,是消费电子、工业控制、仪器仪表等领域的高性价比连接方案。

二、核心参数全面解析

该连接器关键参数严格匹配行业标准,同时优化了接触性能:

  • 电气性能:额定电流3A(AC/DC通用),工作温度范围宽(-40℃~+105℃),可稳定适应高低温交替场景;
  • 机械结构:单排4Pin设计,间距2.54mm(标准间距,兼容市场主流插针),顶部方孔(区别于常规圆孔),塑高8.5mm(PCB布局紧凑),直插安装方式(无需额外工装);
  • 封装与规格:插件封装,排数1排,总孔位数4P,满足小尺寸设备的模块间连接需求。

三、结构设计核心优势

  1. 方孔接触设计
    相比圆孔,方孔与插针的接触面积提升约20%,接触电阻≤10mΩ,减少载流发热;抗插拔磨损性更强(插拔寿命≥1000次),长期使用可靠性更高。

  2. 直插式安装便捷
    直插结构无需复杂焊接辅助,直接插入PCB焊盘即可焊接,安装效率比贴片式提升约30%,适合批量生产场景,降低人工成本。

  3. 耐高温塑壳材料
    采用改性工程塑料(PA66+GF),耐温达105℃,且耐湿热、耐振动(符合GB/T 2423.10振动测试标准),可适应工业设备、汽车电子等恶劣环境。

  4. 紧凑尺寸适配小型化
    塑高仅8.5mm,单排布局,PCB占用面积小(约10mm×5mm),完美适配智能家居、便携式仪器等小型化产品的内部空间限制。

四、典型应用场景

KH-2.54FH-1X4P-H8.5的参数特性使其覆盖多领域需求:

  • 消费电子:智能家居传感器(温湿度、人体感应模块)、小型家电控制板(加湿器、台灯)的信号传输;
  • 工业控制:小型PLC输入输出模块、电机驱动板(小功率)、传感器节点的连接;
  • 仪器仪表:便携式测试仪(万用表、示波器)、医疗监护设备(血压计)的内部模块连接;
  • 汽车电子:车载小功率电路(车内氛围灯、车门传感器)的辅助连接(需配合汽车级认证场景)。

五、选型与使用注意事项

为确保性能稳定,需注意以下要点:

  1. 插针匹配:选用2.54mm间距直插插针,插针外径建议0.8~0.9mm(与方孔边长1.0mm匹配);
  2. 焊接规范:电烙铁温度控制在330~350℃,焊接时间≤3秒,避免塑壳受热变形;
  3. 环境限制:避免长期暴露在强酸、强碱等强腐蚀环境,户外应用需额外防护;
  4. 插拔次数:建议插拔次数不超过1000次,频繁插拔场景可选择带锁定结构的连接器。

六、总结

KH-2.54FH-1X4P-H8.5作为金航标2.54mm系列经典款,以方孔接触可靠性、直插安装便捷性、宽温适应性为核心优势,填补了小间距单排连接器的中端市场需求,是小型化设备连接方案的优选。

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
