KH-2.54FH-1X6P-H8.5是金航标(kinghelm)针对小功率信号/电源传输场景推出的单排直插式方孔排母,兼顾紧凑体积、稳定性能与通用兼容性,广泛适配消费电子、工业控制等多领域应用。以下从核心参数、设计特点、应用场景等维度展开概述:
该产品核心参数严格遵循行业通用规范,关键指标清晰可落地:
方孔结构的核心优势
采用方孔替代圆孔是该产品的核心亮点:接触面积较同规格圆孔提升约15%,实测接触电阻≤18mΩ,可有效降低电流传输损耗;插拔过程中引脚与方孔咬合更紧密,抗振动能力提升30%(对比圆孔排母),避免设备振动导致接触不良,适合车载、工业等场景。
紧凑塑高适配窄空间
8.5mm塑高(PCB板到塑壳顶部高度)较常规10mm塑高排母缩短15%,可适配小型化设备(如智能手环充电座、微型PLC模块)内部布局,无需额外预留空间。
宽温性能覆盖多场景
-40℃+105℃的工作温度范围,覆盖**消费级(0℃+70℃)** 与工业级(-40℃~+85℃) 双场景,满足户外设备(太阳能路灯控制器)、车载辅助电路(行车记录仪电源接口)的极端温度需求。
直插插件的工艺兼容性
直插引脚长度适配标准PCB板厚度(1.6mm),焊接时无需调整;波峰焊温度可控制在260℃以内(3秒),手工焊操作简单,适合中小批量生产与原型开发。
该产品因参数匹配性强,可覆盖以下主流场景:
消费电子领域
智能家电控制板(空调遥控器主板、加湿器传感器接口)、小型可穿戴设备(智能手环充电座、蓝牙耳机充电盒),紧凑体积与稳定电流满足小功率传输需求。
工业控制领域
微型PLC模块(6位I/O接口)、传感器节点(温度/湿度传感器信号输出),宽温性能与抗振动设计适配工业现场环境。
车载电子领域
低功耗车载设备(行车记录仪电源接口、倒车雷达辅助电路),方孔结构的稳定接触可应对车辆行驶中的振动与温度变化。
通信终端领域
小型路由器(辅助电源接口)、交换机(单排信号接口),2.54mm标准间距可与现有板卡无缝对接。
电流降额使用
额定电流3A为持续工作上限,建议实际使用控制在2.5A以内(降额设计),避免长期过载导致引脚发热。
焊接工艺规范
直插引脚焊接时,避免超过280℃的高温烙铁(单次焊接≤3秒),防止塑壳变形;波峰焊需确保引脚完全浸入焊料,避免虚焊。
环境防护建议
若应用于高湿度(>90%RH)或腐蚀性气体环境(化工车间),建议搭配密封胶套或外壳防护,延长产品寿命。
插拔操作规范
插拔需垂直于排母方向用力,避免斜向插拔导致引脚弯曲或塑壳损坏,插拔次数建议控制在500次以内(金航标实测寿命≥600次)。
KH-2.54FH-1X6P-H8.5作为金航标小功率排母系列核心产品,以方孔稳定接触、紧凑塑高、宽温适配为核心优势,兼顾通用兼容性与成本效益,是消费电子、工业控制等领域小数量接口场景的优选方案。该产品每批次均经过全参数检测(接触电阻、绝缘电阻、温度循环测试),确保性能一致性,可满足不同客户的量产需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
