Kinghelm KH-A2508-02A 2.5mm间距直插连接器产品概述

Kinghelm(金航标)KH-A2508-02A是一款专为紧凑空间设计的1×2P直插式连接器,核心针对低压小电流信号/电源传输场景,具备可靠电气性能、宽温适应性及阻燃特性,适用于消费电子、工业控制、小型家电等多领域,是标准化连接方案的高性价比选择。

一、产品定位与核心参数总览

该连接器属于金航标A2508系列,核心参数清晰明确:

  • 结构规格:1排2Pin(1×2P)单排设计,引脚间距2.5mm(工业标准间距),总PIN数2;
  • 安装方式:通孔直插(DIP),兼容手工焊接或自动波峰焊,无需特殊工装;
  • 电气参数:额定电流3A(AC/DC)、额定电压250V(AC/DC),满足低功率电路传输需求;
  • 尺寸参数:板上Z轴高度8.8mm,Y轴底边宽度6.4mm,适配PCB紧凑布局;
  • 环境参数:工作温度-25℃~+85℃,阻燃等级UL94V-0,塑料材质PA46。

二、结构设计与安装适配性

1. 紧凑单排结构

1×2P的单排双针设计简化了设计复杂度,避免多排布局的空间浪费,尤其适合小型化设备(如智能手环充电座、微型传感器模块)的内部连接。

2. 直插式安装优势

通孔直插无需额外压接工具,兼容常规PCB通孔工艺,既支持手工焊接(适合小批量原型制作),也适配自动波峰焊(满足批量生产需求),降低了生产门槛与成本。

3. 标准间距兼容性

2.5mm引脚间距符合行业通用标准,与同类连接器可互换,便于系统集成与升级,无需重新设计PCB。

三、电气性能与触头可靠性

1. 触头材质与镀层

触头采用黄铜(高导电率,接触电阻低),表面镀锡(焊接性优异,减少虚焊风险;同时具备一定防氧化能力,延长使用寿命)。经测试,接触电阻通常≤20mΩ,确保信号/电源传输无明显压降或衰减。

2. 额定参数稳定性

额定3A电流在连续工作下可稳定传输,250V电压满足家用(如220V市电转换后)及工业低压电路要求,避免电气击穿风险,适合大多数低功率应用场景。

四、材料选型与环境适应性

1. 塑料壳体性能

壳体选用PA46(聚酰胺46):

  • 耐高温:长期使用温度可达120℃,远超产品工作温度上限85℃,适应高温环境(如夏季家电内部、工业设备机箱);
  • 机械强度:抗冲击、抗弯折,不易因外力碰撞损坏;
  • 耐化学性:可抵抗弱酸碱腐蚀,适应复杂应用环境。

2. 阻燃与宽温特性

  • 阻燃等级UL94V-0:符合安全标准,可有效降低火灾风险,适用于对防火要求较高的场景(如家电、汽车电子);
  • 宽温范围:-25℃~+85℃覆盖了大多数应用的环境温度(如北方冬季低温、南方夏季高温,或工业设备的室内/室外短时间暴露)。

五、典型应用场景

KH-A2508-02A的紧凑设计与可靠性能使其适用于以下场景:

  1. 小型家电:电饭煲、加湿器、空气净化器的电源接口或控制板信号连接(低功率需求+宽温适应);
  2. 消费电子:智能穿戴(手环、手表)充电座内部连接、蓝牙耳机电池接口;
  3. 工业控制:微型传感器(温度、湿度)信号输出接口、小型PLC辅助电路连接;
  4. 汽车电子:车载低压辅助设备(行车记录仪电源、氛围灯控制)内部连接(满足-25℃~+85℃车载环境)。

总结

KH-A2508-02A凭借2.5mm小间距、直插易安装、宽温阻燃、高可靠性等特点,成为紧凑空间内低功率电路连接的理想选择,可满足多领域的标准化连接需求,是金航标针对中小功率应用推出的高性价比连接器产品。

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
