KH-2.54FH-1X14P-H8.5 单排直插方孔排母产品概述

一、核心规格与结构基础

KH-2.54FH-1X14P-H8.5是金航标(kinghelm)推出的单排14Pin直插方孔排母,核心规格完全匹配行业通用2.54mm间距标准,结构细节清晰可落地:

  • 引脚配置:1×14Pin单排布局,总孔位数14个,适配中等规模电路的多引脚连接需求(如电源+多路信号同时传输);
  • 孔型设计:采用方孔结构,区别于常规圆孔,接触面积提升约15%(对比同尺寸圆孔),插拔时不易因变形导致接触不良;
  • 安装方式:直插式插件封装,适配传统波峰焊、手工焊工艺,PCB板安装孔位易对齐,无需特殊治具;
  • 尺寸参数:塑高8.5mm(塑壳顶部到引脚根部高度),适配常规1.6mm厚度PCB板,安装后垂直空间占用小,适合紧凑型设计;
  • 电气与环境参数:单孔额定电流3A,工作温度范围-40℃~+105℃,覆盖高低温场景无性能衰减。

二、设计优势与性能亮点

该排母针对中小功率电路的稳定连接需求做了针对性优化,核心优势体现在三个维度:

  1. 电气可靠性:单孔3A电流可覆盖大多数消费电子、工业控制的功率需求(如小型电机驱动、传感器供电),避免过载风险;宽温范围适配严寒(北方户外设备)、高温(车载模块)场景,长期使用无接触电阻增大问题;
  2. 结构耐用性:方孔设计解决了圆孔易因插拔变形导致接触不良的痛点,插拔寿命测试可达500次以上(行业标准约300次);引脚采用镀锡工艺,抗氧化性强,焊接后连接牢固,抗振动性能提升20%;
  3. 安装兼容性:2.54mm间距为行业通用标准,PCB板设计无需特殊定制;塑壳采用PA66+GF耐高温工程塑料,焊接时可承受260℃波峰焊温度(1-2秒),塑壳无变形、开裂风险。

三、典型应用场景

结合规格与性能,KH-2.54FH-1X14P-H8.5适用于以下高需求场景:

  • 工业控制:PLC扩展模块、传感器信号接口、小型变频器控制板——宽温适配车间高低温,方孔保证信号稳定传输,避免工业环境振动导致的接触失效;
  • 消费电子:智能家居控制器(灯光/窗帘控制)、小型家电(加湿器/扫地机主板)——3A电流满足小功率驱动,直插工艺适合批量生产,降低组装成本;
  • 汽车电子周边:车载USB扩展、座椅调节模块、氛围灯控制——-40℃~+105℃完全覆盖车载环境温度,方孔抗振动性能优于圆孔,适配汽车行驶中的颠簸场景;
  • 通信设备:小型路由器、交换机内部连接、无线AP模块——14Pin满足多信号(电源+4路数据+8路状态)同时传输,直插安装高效,适合批量贴片后插件的混合工艺。

四、选型与使用注意事项

为确保产品性能稳定,使用时需注意以下要点:

  1. 选型匹配:确认设计需求为单排14Pin、2.54mm间距、方孔直插,避免与圆孔排母混用(接触面积不匹配导致信号干扰);
  2. 焊接规范:手工焊时烙铁温度控制在350℃以内,焊接时间≤3秒;波峰焊需调整温度至260℃±5℃,过炉时间1-2秒,避免塑壳过热;
  3. 插拔操作:配合kinghelm同系列排针使用,插拔时垂直方向均匀用力,禁止斜向插拔导致引脚弯曲或塑壳损坏;
  4. 环境防护:避免长期暴露在潮湿、强酸强碱环境中,若需户外使用需额外做防水处理(如灌封)。

该产品凭借通用规格、可靠性能与亲民成本,成为中小功率电路连接的主流选择,广泛应用于工业、消费电子等领域,年出货量超千万只,市场反馈稳定。

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
