794955-3 产品概述

一、产品简介

794955-3 是 TE Connectivity(泰科电子)面向线束与板对线连接场景推出的一款压接型触头/端子产品。该件支持 18–22 AWG(0.3–0.82 mm²)导线,并适配绝缘外径(OD)在 1.50–3.10 mm 范围内的电缆。触头基材为磷青铜(phosphor bronze),在接触区与整体区域采用不同的镀层工艺以兼顾导电性、耐磨耗及抗腐蚀性能。额定电压为 600 V,适用于中低压工况下的可靠连接需求。

二、主要特性

  • 导线范围:0.3–0.82 mm²(22–18 AWG),覆盖常见的信号与小电流电源线规格。
  • 绝缘范围:适配绝缘外径 1.50–3.10 mm 的线缆,便于与常见线材直径匹配。
  • 触头材质:磷青铜,具有良好的弹性、导电性和机械强度,适合做为弹簧接触件。
  • 镀层结构:
    • 局部镀金区:最小 0.76 μm 金覆盖,且底层有至少 1.27 μm 镍作阻隔层(Ni 下镀)。此结构可提供低接触电阻、优异的耐磨及抗氧化能力,提升接触可靠性和插拔寿命。
    • 局部预镀锡区:最小 2.54 μm 的锡层,用于需要良好可焊性或防腐保护的局部区域。
    • 整体预镀锡:整体覆盖最小 2.54 μm 的锡层,增强元件的整体焊接性与防护性。
  • 额定电压:600 V,适合工业控制、配电与装置内部连接等对电压等级有一定要求的场景。

三、材料与电气/机械优势

  • 磷青铜作为触头基体材料,兼顾导电性与机械弹性,能够在有限的空间内提供稳定的弹簧力,保证长期接触压力和电气连续性。
  • 局部镀金提供极低的接触电阻和优异的抗氧化性能,适用于信号端或需要频繁插拔的接触面,能显著降低接触抖动与接触失效风险。
  • 镍作为金的底层屏障,可以防止金与基材或锡层发生扩散,保证镀层结构长期稳定。
  • 整体与局部的预镀锡处理保证了良好的可焊性与防腐蚀保护,便于后续的波峰或手工焊接工艺。

四、适用场景

794955-3 适用于需要可靠压接及插拔接触的多种电子/电气系统,例如:

  • 工业自动化控制柜内端子连接与线束装配;
  • 家电内部的电源与信号连线;
  • 通讯设备、仪器仪表中信号与电源接口(在 600 V 额定内);
  • 灯具、建筑电气系统中的线缆快速终端解决方案。
    (注:如用于特殊环境或关键安全回路,请根据系统要求确认环境耐受性与认证)

五、安装与使用建议

  • 压接质量:为保证长期可靠性,应使用与该端子相匹配的压接模具和压接工艺,确保压接区金属充分冷压、无松动及过热痕迹。
  • 导线选择:推荐在 18–22 AWG 范围内使用,且导线的绝缘外径在 1.50–3.10 mm 之间,以确保绝缘套与端子体配合良好。
  • 防护与清洁:在装配过程中避免污染接触面;如接触面被污染或氧化,应在受控条件下清洁或更换部件,避免影响接触电阻。
  • 焊接注意:若后续需要焊接,整体的预镀锡层有利于焊接工艺,但应控制焊接温度与时间以免损伤镀层与基材性能。

六、质量与可靠性要点

  • 局部镀金厚度 ≥ 0.76 μm(含镍屏障 ≥ 1.27 μm)显著提高了插拔循环寿命和抗氧化能力,适合接触频繁的应用场合。
  • 预镀锡厚度 ≥ 2.54 μm 为常规工业电气连接提供了可靠的防腐和焊接基础。
  • 该件设计兼顾电气性能与机械强度,能在额定条件下保持稳定的接触电阻与机械固定力。

七、采购与规格注意事项

  • 品牌:TE Connectivity(泰科电子),建议从授权分销商或官方渠道采购以确保正品与可追溯性。
  • 封装:当前资料未提供具体包装信息,订购时请向供应商确认最小包装数量、卷装/盒装形式及出货检验报告。
  • 兼容性:在替换或互换使用时,请核对尺寸、压接舌型及配套模具,以确保与现有端子台或连接器平台兼容。

如需更详细的机械尺寸、温度等级或认证(如 UL 认证、耐振动/盐雾试验数据等),建议提供具体的应用场景或直接查询 TE Connectivity 的产品数据表与规格手册。

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
