TE Connectivity 770904-1 产品概述

一、产品简介

TE Connectivity(泰科电子)型号 770904-1 是一款面向线对端连接应用的端子件,适用于 AWG 18–22 的导线连接场景。该端子采用黄铜触头并做有锡镀层,额定电压 600V,允许的线材绝缘外径(OD)范围为 1.5mm 至 2.39mm。结构紧凑、兼容性好,适合工业控制、电气设备和配线盘等多种应用中作为可靠的电气连接元件。

二、主要参数

  • 型号:770904-1
  • 品牌:TE Connectivity(泰科电子)
  • 描述:端子(terminal)
  • 适用线规(Wire AWG):18 ~ 22 AWG
  • 允许绝缘外径(Insulation OD):1.5 mm ~ 2.39 mm
  • 触头材质(Base Material):黄铜(Brass)
  • 触头镀层(Plating):锡(Tin)
  • 额定电压(Rated Voltage):600 V
  • 封装:无特定包装信息(请参阅厂商资料)

(注:如需完整机械尺寸、温度范围、额定电流等详细规格,请参考 TE Connectivity 的官方数据手册或技术支持。)

三、结构与材料说明

  • 基体材料:黄铜作为触头基材,具有良好的导电性和机械强度,适合经常插拔或振动环境下的可靠接触。
  • 表面处理:锡镀层提高了触点的抗氧化能力和焊接/可接触性,对成本敏感且对耐腐蚀要求不是极端苛刻的场合是常用选择。
  • 形状与结构:典型端子设计包括接线端(压接或插入式)和接触端(插拔或固接),根据面向的接插件或外壳类型实现配对使用。

四、性能与优点

  • 电气安全:额定电压达 600V,满足多数工业和商用电气系统的电压安全需求。
  • 线规适配性:支持 AWG 18–22,覆盖较常见的信号与低功率供电线规范围,便于库存管理与多品种配线。
  • 接触可靠性:黄铜基材加锡镀层能在常规环境下提供稳定的接触阻抗与较低的接触电阻。
  • 装配便捷:设计适配常见压接工具,便于现场或生产线快速装配和检验。
  • 成本与可维护性:锡镀层相对成本较低,维修和更换成本友好。

五、典型应用场景

  • 工业控制柜、配电盘内的导线连接与分支。
  • 家用及商用电器的内部连接与端接。
  • 仪表与测试设备的接线端子。
  • 线束制造和电子装配线中作为通用端子使用。
    (重要提示:若用于高振动或苛刻环境(如海洋、化工腐蚀性气氛、高温等),请核实防腐、耐高温和机械锁紧要求,或选用专用镀层与固定方式。)

六、装配与使用建议

  • 压接工具:建议使用与端子型腔匹配的专用压接钳或模具,保证压接高度和压接力符合规范,避免松动或导体损伤。
  • 线缆准备:去皮长度应与端子规格匹配,绝缘层未进入压接端会导致接触不良;绝缘外径应处于 1.5–2.39 mm 范围内以确保可靠固定。
  • 质检方法:实施拉力试验、目视检查压接形态和电阻测量,确保接触可靠。
  • 存储与搬运:置于干燥、无腐蚀性气体的环境,避免长期潮湿和盐雾暴露以防镀层损耗。

七、选型与采购建议

  • 确认配套件:在选型前确认此端子与目标接插件或母座的配合兼容性(尺寸与极性)。
  • 参考资料:获取并核对 TE Connectivity 的官方数据手册(Datasheet)和工程图纸,了解完整的机械尺寸、额定电流、温度范围和认证信息(如 UL/CSA 等)。
  • 评估环境:根据使用环境(温度、湿度、振动、化学介质)决定是否需要更高等级的镀层(如镀镍、镀金)或不同基材。
  • 批量采购:如需批量使用,建议向 TE 授权分销商确认可用性、包装形式和最小采购量,以便合理备货。

八、总结

TE Connectivity 770904-1 为一款通用性强的黄铜锡镀端子,适配 AWG 18–22 的常见线规,并在 600V 额定电压范围内提供可靠的电气连接。其机械与电气特性适合多数工业与商用电器接线场合,但在最终应用前建议查阅官方数据手册并根据现场环境做必要的选型和验证。

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
