Kinghelm KH-A2508-02AW 连接器产品概述

一、产品定位与核心设计方向

KH-A2508-02AW是金航标(Kinghelm)推出的2.5mm间距单排弯插连接器,聚焦小间距、高可靠的基础电子连接需求,针对消费电子、工业控制、IoT设备等领域的紧凑布局场景,提供稳定的信号与小功率电源传输方案。其核心设计围绕「紧凑空间适配+可靠电气连接+工业级环境耐受」三大方向,适配各类小型化设备的内部板间或线板连接需求。

二、关键技术参数详细解读

该连接器的参数设计兼顾兼容性与实用性,具体核心参数及应用价值如下:

  • 针脚与间距:采用1×2P单排双针结构,2.5mm标准间距——行业通用间距规格,兼容绝大多数PCB板的开孔布局,避免因间距特殊导致的适配难题;每排2针的设计满足基础信号/电源通道需求,避免多余针脚占用空间。
  • 安装方式:弯插设计——区别于直插的垂直安装,弯插可实现PCB板侧面或倾斜方向的连接,大幅节省板上垂直空间,尤其适合设备内部布局紧凑(如小型PLC、IoT节点)的场景。
  • 电气性能:额定电流3A(AC/DC通用)、额定电压250V——满足5V/12V小功率电源传输(如12V/2A电源),同时支持低电压信号传输(如数字信号、模拟传感器信号),覆盖消费电子与工业轻载场景的核心需求。
  • 物理尺寸:Z轴板上高度6.4mm、Y轴底边宽度8.8mm——超紧凑尺寸,即使在10mm以内的垂直空间内也可安装,适配小型化设备的内部空间限制。
  • 环境适应性:工作温度范围-25℃~+85℃、阻燃等级UL94V-0——可耐受工业级环境的温湿度波动(如车间、户外IoT节点的昼夜温差),PA46塑料的V-0阻燃性可避免设备故障时的起火风险,符合安全规范。

三、材料与工艺特性

产品的材料选择直接决定可靠性,KH-A2508-02AW在触头与塑料两部分均采用针对性设计:

  • 触头组件:基底为黄铜,表面镀锡——黄铜导电率高(约20%IACS),降低传输损耗;锡镀层熔点低(232℃),适配手工焊、波峰焊等常见焊接工艺,且锡在常温下不易氧化,可长期保持稳定的接触电阻(避免因氧化导致的信号中断或电源压降)。
  • 塑料外壳:采用PA46(聚己二酰丁二胺)材质——相比普通PA66,PA46的耐温性更好(短期耐温可达260℃,匹配波峰焊温度)、机械强度更高(耐冲击、耐蠕变,长期使用不易变形),同时UL94V-0阻燃等级确保安全。

四、典型应用场景

结合参数与材料特性,该连接器适用于以下场景:

  1. 消费电子:小型家电(如智能台灯、加湿器、空气净化器)的内部电源/信号连接——紧凑尺寸适配家电内部的小空间,3A电流满足低功率电源需求;
  2. 工业控制:小型PLC的I/O模块、传感器接口板的板间连接——2.5mm间距支持多通道并行布局,-25℃~+85℃温宽适配车间环境;
  3. IoT设备:低功耗传感器节点(如温湿度、光照传感器)的内部连接——弯插设计节省节点体积,PA46材质耐受户外轻微温湿度变化;
  4. 汽车辅助电子:车载小显示屏、辅助传感器(如倒车雷达小模块)的内部连接——V-0阻燃性符合汽车电子的安全要求,3A电流满足辅助系统的低功率需求。

五、安装与使用注意事项

为确保产品性能与可靠性,使用时需注意以下要点:

  • 安装对齐:弯插安装时需确认PCB板开孔位置与针脚对齐,避免针脚弯曲变形(弯曲会导致接触不良或焊接困难);
  • 焊接规范:手工焊烙铁温度控制在300℃350℃,焊接时间不超过3秒;波峰焊温度控制在240℃260℃(匹配PA46耐温),避免塑料熔化或变形;
  • 电流限制:严格遵循额定3A电流,禁止过载(过载会导致触头发热氧化,缩短使用寿命);
  • 环境防护:避免长期暴露在高湿度(>90%RH)、腐蚀性气体(如硫化氢)环境中,虽有锡镀层防护,但仍需注意环境隔离。

KH-A2508-02AW凭借紧凑设计、可靠性能与宽环境耐受能力,成为小型化设备内部连接的高性价比选择,适配多领域的基础电子连接需求。

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
