440129-2 产品概述

一、产品简介

440129-2 为 TE Connectivity(美国泰科)旗下的线对板插座外壳(Housing, Receptacle),属于 HPI 系列的低间距、双位(1×2P)连接器。该件为 2.00 mm(0.079 in)中心距、单排 2 针的压接式线端外壳,天然白色塑料材质,设计用于电源与信号的线对板连接,提供可靠的插接保持功能(Mating Retention),适用于小型化电子装置和线束连接场合。

二、主要技术参数

  • 插孔结构:1×2P(单排,2 位)
  • 中心距(Pitch):2.00 mm(0.079 in)
  • 接合方式:压接(Crimp)线端插入外壳
  • 颜色:Natural(白色)
  • 是否带锁扣/翅:不带锁扣,不带翅
  • 阻燃等级:UL94 V-0
  • 工作温度:-25 ℃ ~ +85 ℃
  • 典型应用类别:Wire & Cable、Power & Signal、Wire-to-Board

三、结构与特性

440129-2 外壳采用高阻燃塑料制造,符合 UL94 V-0 等级,具备良好的防火与绝缘性能。2.00 mm 的中心距在小型化设计中提供紧凑的布局,同时仍能兼顾一定的电流传输能力与机械刚性。外壳内部设有压接触点定位槽,支持与对应的压接端子配套使用(需选用与 TE 配套的压接件与端子),并具备插接保持结构以确保与印制电路板或对接端的可靠接触。该型号不含外部锁扣或固定翅片,适用于需要简洁外观与紧凑空间的场合。

四、典型应用场景

  • 小型电源与信号线束的线对板连接
  • 家电控制模块、工业控制器内部分线、传感器线缆接口
  • 通信设备、仪器仪表以及医疗家用类电子产品(在符合温度与安全要求下)
  • 产品试样与原型开发中作为通用的 2 针线对板连接器

五、安装与配套建议

  • 压接端子:建议使用 TE 原厂对应型号的压接端子,配合合适的压接工具以保证端子与导线的可靠电气与机械连接。
  • 配对连接器:应选用与 2.00 mm 中心距、2 位匹配的 PCB 插针排(Wire-to-Board header)以确保插接配合与定位。
  • 线径选择:根据实际电流与线缆规格选用合适的导线截面并参照端子规格进行压接,避免超载。
  • 安装环境:避免超过 -25 ℃ ~ +85 ℃ 的工作温度范围,避免长期受潮或强腐蚀性气体环境。

六、使用注意事项

  • 由于本型号不含外部锁扣,需确认装配后插头与插座的干涉及固定方式,必要时配合机械限位或粘接固定以防震动脱落。
  • 在批量生产时推荐作电气性能(接触电阻、耐压)与机械耐久性(插拔次数)验证,确保满足终端应用的可靠性要求。
  • 储存与运输应避免高温、潮湿与挤压变形,防止塑料件翘曲或端口污染。

总结:440129-2 以其紧凑的 2.00 mm 中心距、UL94 V-0 阻燃等级和简洁的压接型结构,适合对体积与可靠性有要求的线对板连接应用。正确匹配 TE 的压接端子与 PCB 插针配对器,并按规范装配与测试,可在各类小型电源与信号连接场合中提供稳定可靠的性能。

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
