1971783-1 产品概述

一、产品简介

1971783-1 为 TE Connectivity(泰科电子)的一款压接式插座触头(female contact),面向电源连接应用设计。该触头适配 19–16 AWG(约 0.65–1.3 mm²)导线,允许绝缘外径(OD)范围 2.0–3.3 mm,触头材质为磷铜(phosphor bronze),表面镀锡(Sn),额定电压 600 V(VAC / VDC)。产品用于需要可靠电气接触与机械锁固的插座端子系统,通常配合相应的外壳和接插件组件使用,提供长期稳定的电源传导解决方案。

二、主要特性

  • 适配导线范围:AWG 19–16(0.65–1.3 mm²),覆盖常见的电源和信号电缆截面。
  • 绝缘外径兼容:2.0–3.3 mm,便于与多种线缆和外壳设计配合。
  • 触头材质:磷青铜,具备良好的弹性、机械强度和导电性。
  • 表面处理:镀锡(Sn),提升耐腐蚀性和焊接/压接性能,适合电源连接但不适合高循环精密信号接触要求。
  • 额定电压:600 V(AC / DC),满足多数中低压电源系统的绝缘与安全要求。
  • 结构特性:压接端子设计,结合三重锁定(power triple-locking)结构,提供多点机械锁固与抗振性能。

三、材料与电气/机械性能解析

  • 磷青铜触头:以其良好的弹性回复和耐磨性,确保长期反复插拔或振动环境下仍维持接触力。
  • 镀锡层:锡层在电源端子上常用于改善可焊性、抗氧化及降低接触电阻,适用于需要可靠电流传导的场合;在高腐蚀或低电阻精密场景下可评估是否需采用其他镀层。
  • 600 V 额定:指绝缘体系与端子设计在该电压下能满足耐压和安全规范,但实际电流承载能力应依据导线截面、端子散热条件和系统要求来确定并按相关标准核算。

四、装配与压接要求

  • 使用制造商推荐的压接工具与模具进行端子压接,保证导体与压接筒之间的压接质量和一致性。
  • 剥线长度与压接位置应严格按照产品说明书(或相应压接工艺文件)控制,避免露出过长或剥线不足导致接触不良或绝缘破损。
  • 建议对压接件进行目检、尺寸测量及拉力测试(拔出力)验证,确保每批次装配满足机械与电气可靠性要求。
  • 对于关键电源回路,建议完成接触电阻和温升测试以确认长期载流能力。

五、应用场景

  • 各类电源模块和配电组件的插座端子;
  • 工业设备、控制柜、仪器仪表的可插拔电源连接;
  • 汽车电子(非高安全关键的车载电源分配)、通信电源及电源模块内部连接;
  • 需要抗振动、长期稳定导电的连接场合,尤其是与三重锁定外壳配合使用时可提升插拔可靠性。

六、安全与可靠性建议

  • 虽标注 600 V 额定,应结合实际工作环境(温度、湿度、振动、化学腐蚀等)评估端子和线缆整体性能。
  • 镀锡触头适合多数电源场景,但在需要低接触电阻或多次插拔的精密信号端口可考虑更高阶的镀层方案。
  • 采用制造商推荐的端子与外壳配对,确保三重锁定机制正确实现,否则可能影响锁固效果与接触稳定性。

七、选型与采购注意事项

  • 确认配套外壳/接插件型号,核实三重锁定结构在目标组件中的实现方式与锁固位置。
  • 获取并遵循 TE 提供的压接工艺文件、工具清单与剥线长度数据表,避免因工艺差异导致接触不良。
  • 如需符合特定认证(例如 UL、CSA 等),在采购前核实该端子型号的认证状态与规格表中的合规声明。
  • 采购时注意包装与标识,确保来源可靠以避免仿制产品带来的风险。

总结:1971783-1 为面向电源应用的高可靠性压接式插座触头,结合磷铜材质与镀锡处理以及三重锁定结构,适用于对机械锁固和长期导电性能有较高要求的连接场合。正确的压接工艺和与制造商配套的组件配合,是发挥该端子性能的关键。

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
