TE Connectivity 2306654-3 — SPRING FINGER 1.8H 产品概述

一、产品概述与定位

2306654-3 为 TE Connectivity(美国泰科)AMP 系列中的屏蔽弹簧片(Spring Finger)元件,标注为 SPRING FINGER 1.8H。该件为有源产品,通常以卷带(Tape & Reel, TR)形式供货,适用于需要可靠接地/屏蔽接触的电磁兼容(EMC)和机壳对板接触场合。元件本体由铜合金制成,表面镀金,连接方式为焊接,工作温度范围为 -40°C 到 85°C,适配常见工业与电子产品环境。

二、主要规格与物理特性

  • 制造商:TE Connectivity (AMP Connectors)
  • 基本产品编号:2306654(变体 -3)
  • 类型:屏蔽弹簧片(Shield Spring Finger)
  • 尺寸:宽度 0.039"(1.00 mm),高度 0.071"(1.80 mm)
  • 材料:铜合金(保证导电性与弹性)
  • 镀层:镀金(提高耐腐蚀性和低接触电阻)
  • 连接方法:焊接(适用于 PCB 固定与电气连接)
  • 工作温度:-40°C ~ 85°C
  • 包装:卷带(TR),便于自动化贴装与批量生产

这些物理尺寸和材料选择使该弹簧片在保持良好弹性接触力的同时,兼顾长期电性能与抗腐蚀性,适合用于机壳与 PCB 间的屏蔽接地、接触弹性要求较高的连接点。

三、功能与应用场景

2306654-3 的主要功能是提供弹性导电接触点,用于:

  • 机壳到 PCB 的屏蔽接地(消除 EMI/RFI 干扰)
  • 可拆卸机箱/面板的接地缓冲与定位
  • 对准并保持金属盖/框与电路板之间的电接触
  • 用于连接导电垫圈或吸音/屏蔽垫的接触元件

典型应用行业包括通信设备、网络设备、工业控制盒、消费类电子机箱、测试与测量设备等。由于工作温度上限为 85°C,建议用于非严格汽车高温环境的场合或需确认环境散热条件。

四、优点与设计考量

优点:

  • 镀金表面:提高接触可靠性、降低氧化导致的接触电阻增大。
  • 铜合金材质:兼顾良好的导电性与弹性回复能力。
  • 小型化尺寸:适配紧凑型电路板与模块化机箱设计。
  • 卷带包装:利于自动化 SMT/贴片或人工焊接前的批量装配。

设计注意事项:

  • 确认焊接方式与工艺:虽然连接方法标注为“焊接”,但实际装配时需参照制造商的焊接/回流/波峰焊建议和可耐受的温度循环。
  • PCB 固定与支撑:弹簧片受力点需有足够板面或机械支撑,避免长期振动引起疲劳失效。
  • 接触面配合:与机壳接触的对应凸台或镀层应保证材料兼容,避免 galvanic corrosion(异金属腐蚀)。
  • 环境温度限制:若工作环境可能超过 85°C,需评估替代件或采取降温/隔热设计。

五、焊接与装配建议

  • 参照 TE Connectivity 官方数据手册获取推荐的焊接温度曲线与工艺限制。部分弹簧件可接受选择性波峰或回流,但要避免过高温度导致弹性退化。
  • 在贴装前检查卷带防护与方向,确保弹簧片在 PCB 上的安装方向与接触面朝向一致。
  • 如采用波峰焊或浸锡,建议对镀金层厚度、底层镀层材料及其可焊性进行确认,避免焊接不良。
  • 装配后应进行功能性接触测试(接触电阻、接触压力测试),以确认屏蔽/接地效果满足设计要求。

六、采购与验证建议

  • 型号后缀(如 -3)可能代表包装、材料或工艺的变体,采购前请核对完整的料号与 datasheet 以确认与设计匹配。
  • 在设计验证阶段建议获取样品并进行环境循环、接触寿命、接触电阻与振动/机械疲劳测试,确保长期可靠性。
  • 若需符合特殊合规(如 RoHS、REACH 或汽车 AEC-Q 系列),请向 TE 或授权代理确认具体合规声明与证书。

总结:2306654-3 为一款小型化、镀金处理的铜合金屏蔽弹簧片,适合用于机壳到 PCB 的弹性接地与屏蔽接触场景。其尺寸与材料使其在电子设备的 EMC 设计中具有良好的可用性,但在具体应用前应参照 TE 官方资料完成焊接工艺与可靠性验证。

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
