TE Connectivity 794955-1 产品概述

一、规格与基本特性

794955-1 为一款用于电源连接的压接式触头(Power Contact / Pin),适用于 22–18 AWG(约 0.3–0.82 mm²)导线。主要电气与机械参数如下:

  • 额定电压:600 VAC
  • 适配线规:AWG 18–22(0.3–0.82 mm²)
  • 允许绝缘外径(OD):1.5 mm ~ 3.1 mm
  • 触头基材:黄铜
  • 镀层:锡(提高耐蚀性及可焊性)
  • 连接方式:压接(Crimp, Wire & Cable)
  • 工作温度范围:-40 ~ 105 °C(-40 ~ 221 °F)

该触头以简洁的压接结构提供可靠的电气传导路径,适合用于中低电压电源线连接场合,兼顾导电性能与机械强度。

二、材料与电气性能优势

触头采用黄铜基材并经锡镀层处理。其主要优势包括:

  • 良好导电性:黄铜本身具有较低电阻,适合传输较大电流的电源连接。
  • 抗氧化与可焊性:锡镀层可防止铜氧化、提高长期接触可靠性,并方便在需要时进行额外焊接处理。
  • 机械耐久:压接连接在正确的工具与工艺下能提供稳定的力学保持力与低接触电阻。

额定 600 VAC 表明该触头适用于多数工业与商用电源系统,需结合实际绝缘与壳体设计以满足安全规范。

三、典型应用场景

794955-1 常见于需要可重复或可靠压接的电源接线场景,包括但不限于:

  • 工业控制设备电源线接入
  • 电机驱动器与配电模块内部接线
  • 电源模块、配线盒与线束制造
  • 商用电器与配件中的电源触点 在这些场合,该触头可作为线到线或线到模块的电气连接介质,借助合适的端子座或插针对接实现可靠配合。

四、安装与压接要点

为了确保接触可靠性与长期稳定性,请注意如下安装细节:

  • 使用推荐的压接工具和模具:手工或机械压接时,应采用与该触头尺寸相匹配的压接头,避免过压或不足压导致接触不良或导线损伤。
  • 剥线长度与绝缘匹配:剥线长度应使导体完全进入压接区且不外露,绝缘外径在允许范围 1.5–3.1 mm 内以保证绝缘墙体与壳体匹配。
  • 压接后检测:建议进行拉力测试及外观检查,确认线束未滑出且无明显变形或裂纹,接触面无氧化残留。
  • 环境与应力缓解:必要时在接头处使用热缩套管、线夹或应力消除装置,避免振动或弯曲疲劳导致接触损坏。

五、兼容性与选型建议

  • 确认配合件:该触头为压接型 Pin,应与对应的插座、壳体或母触头尺寸匹配。选型时请核对插拔配合公差、插入力与保持力。
  • 线规范围校验:确保所用导线截面积在 0.3–0.82 mm²(AWG 22–18)范围内,使用过细或过粗导线都会影响压接质量。
  • 环境要求评估:若工作环境存在高温、潮湿、腐蚀性气体或盐雾,应评估锡镀层的长期耐蚀能力或考虑特殊表面处理/密封措施。
  • 额定电流匹配:尽管本件提供额定电压信息,实际电流能力需结合导线截面积、触头接触面积与散热条件计量,必要时参考供应商的详细额定电流资料或进行热测试。

六、可靠性与维护

  • 长期可靠性:在合适的压接工艺与环境下,锡镀黄铜触头可维持低接触电阻与稳定机械接触,适合多种中功率电源连接。
  • 定期检查:在关键设备维护周期内应检查接点温度、紧固状态与有无氧化/松动迹象;对于频繁插拔的接口,应关注插拔次数对镀层与保持力的影响。
  • 储存与处理:避免长期暴露于潮湿、酸碱或腐蚀性气体环境中,未使用的触头应置于干燥、封闭包装内,以保持镀层完整性。

七、采购与技术支持提示

  • 型号核对:订购前请核实完整料号与包装信息(本处未标明封装形式),并向供应商确认包装数量与出货条件。
  • 获取数据表:如需更精确的机械尺寸、额定电流、插拔寿命等详细参数,请向 TE Connectivity 获取官方 datasheet 与推荐的压接工具、容许公差与测试标准。
  • 备件管理:对于批量装配项目,建议统一采购与工具配置,建立压接工艺参数与检验流程,以保证批次一致性与可靠性。

总结:794955-1 是一款面向 22–18 AWG 电源线的压接式黄铜锡镀触头,适用于多种中低压电源连接应用。其材料与结构兼顾电气性能与可靠性,但实际性能与寿命依赖于正确的压接工艺、配套零件与使用环境。若需进一步的机械图纸、额定电流或认证信息,请联系 TE Connectivity 或其授权代理获取官方资料。

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.
