KH-2.54PH180-1X8P-L11.5 排针产品概述

一、产品核心定位与基本属性

这款KH-2.54PH180-1X8P-L11.5排针是金航标(kinghelm)推出的通用型直插式单排方针排针,属于2.54mm间距系列的经典型号。它针对电子设备中信号传输、中小功率电源连接的需求设计,兼顾“高可靠性”与“低成本”,适合批量应用于消费电子、工业控制等多个领域。

从基本属性看,它采用单排8PIN(1x8P) 结构,方针设计(区别于圆针),直插式安装(需通过PCB插件焊接固定),间距严格遵循2.54mm的行业标准,塑壳为黑色,整体设计紧凑,适配大多数常规PCB布局。

二、关键技术参数详解

这款排针的核心参数覆盖电气、机械、环境三个维度,具体如下:

1. 电气参数

  • 额定电流:3A(AC/DC通用)—— 满足中小功率设备的电源/信号传输需求,比如小型电机控制、传感器供电等场景;
  • 工作温度范围:-40℃~+105℃—— 耐高低温性能优异,可适应户外低温环境(如北方冬季设备)或工业高温环境(如设备内部散热区域)。

2. 机械参数

  • 结构类型:1x8P单排、方针;
  • 间距:2.54mm(行业标准间距,适配90%以上的常规PCB设计);
  • 配合针长度:6mm—— 保证与排母插拔时的接触深度,减少接触不良概率;
  • 塑高:2.5mm—— 紧凑设计,节省PCB正面空间,适合轻薄化设备;
  • 端接针长度:3mm—— 焊接时与PCB焊盘的结合长度适中,既保证焊接牢固(避免虚焊),又不会因过长导致PCB背面占用过多空间。

3. 外观与材料

  • 颜色:黑色塑壳(耐脏、抗紫外线老化性能较好);
  • 接触件:方针材质通常为黄铜(部分型号镀金,提升导电性与抗氧化性)—— 黄铜的导电性与机械强度平衡,适合多次插拔场景。

三、结构设计与工艺特点

这款排针的设计针对“稳定连接”与“易安装”两个核心需求,具体工艺特点如下:

1. 方针设计优势

相比圆针,方针的接触面积更大,插拔时与排母的接触更充分,能有效降低接触电阻,减少信号衰减或电流损耗;同时方针的机械强度更高,多次插拔后不易变形,延长使用寿命。

2. 直插安装适配性

直插式结构无需额外工具,直接插入PCB焊盘即可焊接,工艺简单且成本低;端接针长度3mm的设计,既能保证焊接牢固(避免焊接后脱落),又不会因针脚过长导致PCB背面干涉其他元件。

3. 塑壳工艺细节

黑色塑壳采用耐高温工程塑料(如PA66),耐温性能与塑壳强度匹配工作温度范围;塑高2.5mm的紧凑设计,让排针在PCB上的占用空间极小,适合对体积有要求的设备(如小型遥控器、穿戴设备辅助模块)。

四、适配场景与应用优势

这款排针因参数均衡、成本可控,广泛应用于以下场景:

1. 常见应用场景

  • 消费电子:家电遥控器(信号连接)、小型电子玩具(电源/控制信号)、智能穿戴设备辅助模块;
  • 工业控制:PLC扩展模块(传感器接口)、小型仪器仪表(数据传输)、低压配电设备(控制信号);
  • 通信设备:小型路由器/交换机(状态指示灯接口)、物联网终端(传感器连接);
  • 汽车电子:低端车载小模块(如座椅调节辅助接口,需耐温)。

2. 核心应用优势

  • 高可靠性:方针接触稳定+宽温范围,减少因环境变化导致的连接故障;
  • 低成本:2.54mm是通用间距,无需定制PCB,批量采购成本低;
  • 易安装:直插焊接工艺简单,适合流水线批量生产;
  • 兼容性强:适配大多数常规排母(2.54mm间距),无需担心配合问题。

五、选型与使用注意事项

1. 选型要点

需确认三个核心参数:PIN数(1x8P)、方针类型、直插安装—— 若需圆针或双排结构,需选择同系列其他型号(如KH-2.54PH180-2X8P等)。

2. 使用注意事项

  • 焊接温度:焊接时烙铁温度建议控制在260℃以内(避免超过塑壳耐温极限,导致塑壳变形);
  • 插拔力度:与排母插拔时避免用力过猛,防止方针弯曲或塑壳损坏;
  • 存储环境:存储时避免潮湿(湿度≤60%)、高温(≤40℃),防止塑壳老化或方针氧化;
  • 焊接质量:焊接后需检查焊盘是否有虚焊、针脚是否弯曲,确保连接可靠。

这款KH-2.54PH180-1X8P-L11.5排针是金航标针对通用连接需求推出的高性价比产品,参数均衡、工艺成熟,适合大多数中小功率电子设备的信号/电源连接场景。

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.
