KH-1.27PH180-2X5P-L7.2-SMT 双排立贴排针产品概述

一、产品核心定位与基本规格

KH-1.27PH180-2X5P-L7.2-SMT是金航标(kinghelm)针对高密度小型化电子设备推出的立贴式排针,主打小间距、高可靠性连接。核心规格明确:

  • 总PIN位:10位(双排2×5P布局,符合标准双排排针通用接口);
  • 间距(Pitch):1.27mm(行业常见小间距,适配紧凑PCB空间);
  • 行距:1.27mm(双排PIN对齐,安装一致性强,无错位风险);
  • 安装方式:立贴(SMD)—— 直接焊接于PCB表面,无需钻孔,兼容自动化回流焊工艺;
  • 针型:方针(接触面积较圆针更大,连接稳定性更优);
  • 附加特征:带柱(立贴时提供支撑与定位,避免焊接偏移);
  • 基础尺寸:配合针长4mm(插入深度适配常规排母)、塑高1mm(矮身设计,减少PCB占用空间)。

二、关键结构与材质特性

产品设计围绕可靠性、耐环境性展开,核心结构与材质优势明显:

1. 触头系统:黄铜+镀金,低阻耐腐

触头采用黄铜材质(导电性能优异、机械强度适中),表面镀纯金(镀层厚度符合工业标准):

  • 镀金层可将接触电阻控制在≤10mΩ(初始),插拔1000次后仍≤50mΩ;
  • 耐氧化、耐腐蚀能力强,适应潮湿、轻度盐雾等环境(如户外传感器、工业模块)。

2. 塑壳设计:矮身带柱,适配小型化

塑壳采用耐高温工程塑料(耐回流焊峰值温度260℃),具备两大特点:

  • 塑高仅1mm:大幅降低整体高度,满足智能穿戴、小型医疗设备等紧凑空间需求;
  • 带柱结构:焊接时可嵌入PCB定位孔(或直接支撑),防止立贴排针倾斜、偏移,提升焊接良率(良率≥99%)。

3. 方针结构:接触稳定,适配性广

相比圆针,方针的平面接触界面与对应方针排母配合时,接触面积提升30%以上,可减少接触电阻波动,尤其适合信号传输要求稳定的场景(如传感器模拟信号、通讯模块数字信号)。

三、电气与环境性能参数

产品性能覆盖工业级应用需求,关键参数如下:

  • 额定电流:1A/单PIN(可满足低功率供电、信号控制需求;多PIN并联可提升电流承载能力,需根据实际设计调整);
  • 工作温度范围:-40℃~+105℃(覆盖户外低温、机房高温等典型环境,符合工业级温度标准);
  • 绝缘电阻:常态≥100MΩ(500V DC),潮湿环境(40℃/95%RH)≥10MΩ,满足电气绝缘要求;
  • 环保标准:符合RoHS无铅要求,镀金层无有害物质,适配出口产品需求。

四、典型应用场景

因小间距、立贴、矮塑高的特性,该排针适用于以下高密度场景:

  1. 智能穿戴设备:智能手环、蓝牙耳机的内部模块连接(PCB空间紧凑,需1.27mm小间距);
  2. 智能家居传感器:温湿度传感器、门窗传感器的信号输出接口(耐温、稳定连接);
  3. 工业控制小模块:PLC扩展模块、电机驱动单元的内部信号连接(适应-40~105℃环境);
  4. 通讯终端设备:小型路由器、交换机的扩展接口(多排针布局,高密度安装);
  5. 医疗电子设备:小型监护仪、血糖检测仪的内部组件连接(环保镀金,耐腐蚀)。

五、安装与配合注意事项

为确保性能与焊接良率,需注意以下要点:

  1. 焊接工艺:优先采用回流焊(符合IPC-A-610标准),避免手工焊接时温度过高(超过260℃会损伤塑壳);带柱需与PCB定位孔配合,防止偏移;
  2. 排母匹配:需选择方针、1.27mm间距、2×5P的排母,配合针长4mm需确认排母针孔深度≥4mm,避免插入过浅导致接触不良;
  3. PCB设计:焊盘布局需与2×5P PIN位对齐(间距1.27mm),立贴焊盘需预留适量锡量(避免短路);
  4. 存储要求:未焊接产品需存于干燥环境(湿度≤60%),温度0℃~35℃,防止镀金层氧化、塑壳老化。

该产品凭借小间距、高可靠性、矮身设计,成为小型化电子设备内部连接的优选方案,可满足多数工业级、消费级场景的信号与低功率电流传输需求。

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
