产品详情

这是 1 2605131s210f6,一款由 BQUQ 在中国东莞生产的冲压端子和接触件。它是一种高精度电气接触元件,专为连接器、继电器和开关组件中的可靠电流传输而设计。我们确保平整度一致达到 0.02mm,毛刺高度低于 0.05mm,表面光洁度 Ra 0.8µm,硬度为 40-45 HRC,确保在反复插拔下具有长使用寿命。

我们如何在冲压端子上实现 ±0.01mm 公差

高速冲压薄金属会产生微弯曲和回弹。我们通过使用五级成型顺序的级进模来补偿这一点,而非单次冲压。每个阶段在开始生产前都经过光学测量。结果是接触梁的位置公差为 ±0.01mm,端子宽度在 10,000 件批量中保持在 ±0.015mm 以内。我们以每分钟 150 次冲程运行冲床,但在关键尺寸的最终校准阶段会降至 80 次。

材料选择:为何选用 C5210 磷青铜和 BeCu C172

对于 1 2605131s210f6,我们提供两种标准材料。C5210 磷青铜提供 590 MPa 的抗拉强度和优异的抗疲劳性能——非常适合承受 100,000 次以上循环的弹簧触点。铍铜 C172 是可选材料,当您需要更高导电率(22% IACS)和热处理后高达 45 HRC 的硬度时使用。两种材料均附带轧制证书,确认化学成分和晶粒尺寸,可追溯至卷料批次号。

热处理和硬度:40-45 HRC 且无脆性

我们在真空炉中于 315°C 下对 C172 进行时效硬化处理 2.5 小时,以达到 40-45 HRC。这不是表面硬化层——硬度贯穿整个 0.4mm 厚度。该工艺消除了内应力,因此端子压接到电线上时不会变形。对于 C5210,我们采用 200°C 下 1 小时的去应力退火,提高回弹一致性,并将硬度保持在 90-100 HRB,符合高循环应用的原始规格。

表面处理和电镀:Ra 0.8µm 和可选选择性镀金

冲压状态下,1 2605131s210f6 的接触区域表面光洁度为 Ra 0.8µm,可降低电阻并防止微电弧。如果您需要电镀,我们仅在接触尖端提供选择性镀金(厚度 0.76µm),保留基底金属以确保可焊性。每第 500 件进行 90° 弯曲测试以验证镀层附着力。我们还提供锡镀层(2-5µm),适用于需要耐腐蚀性的低成本应用。

每次发货前检验:五点检查

每批 1 2605131s210f6 在包装前均经过 40 倍光学比较仪检查。我们检查五个参数:端子宽度、接触间隙、毛刺高度、表面光洁度和镀层厚度。每 10,000 件批次中抽取 32 件样品,使用数字千分尺和轮廓仪进行检测。如果任何一件不合格,整批将被隔离并重新生产。我们提供包含实际测量值的检验报告,而非仅盖章的合格/不合格证明。

| 参数 | 1 2605131s210f6 规格 | 公差/范围 | |-----------|--------------------------|------------------| | 材料(标准) | C5210 磷青铜 | 0.4mm 厚卷料 | | 材料(可选) | BeCu C172 | 0.4mm 厚卷料 | | 端子宽度 | 2.8mm | ±0.015mm | | 接触梁长度 | 6.2mm | ±0.02mm | | 硬度(铍铜) | 40-45 HRC | 真空时效 | | 硬度(磷青铜) | 90-100 HRB | 去应力处理 | | 表面光洁度(接触区域) | Ra 0.8µm | 最大 | | 毛刺高度 | 0.05mm | 最大,任何边缘 | | 平整度(冲压后) | 0.02mm | 最大 | | 交期 | 5 天 | 自图纸批准起 | | 起订量 | 无起订量 | 任意数量 |

为什么我们 5 天发货,而其他厂家需要 15 天

我们的模具车间备有 1 2605131s210f6 的预硬化模具库存。这意味着我们省去了 10 天的模具制造等待时间。一旦您批准样品,我们就在已为该零件号设置好的 25 吨高速冲床上运行您的订单。典型的 50,000 件订单需要 4 小时冲压时间和 1 天检验时间。从图纸批准到东莞本地自提交货,只需 5 天。对于出口,另加 2-3 天用于货运集拼。

这种冲压端子的最小起订量是多少?

没有起订量——您可以订购 1 件用于原型测试,或 100 万件用于批量生产,单价将反映数量梯度。

您能根据我的应用更改材料或电镀吗?

可以,我们可以切换到 C172 铍铜或添加选择性镀金,但任何材料变更都需要 24 小时的模具重新鉴定,并在批量生产前提供新样品供您批准。

您如何保证关键连接器零件的质量?

我们对每批产品进行五点检验,包括光学比较仪和轮廓仪检查,并向您发送每批实际测量值的报告——而非通用证书。

如果我需要定制冲压模具,交期是多久?

如果您需要新模具,我们在 10-15 天内交付可用的级进模,之后 3 天内交付首件;对于现有的 1 2605131s210f6 模具,标准交期为 5 天。

该零件在我们的东莞工厂中国制造,我们在汽车和工业连接器精密制造领域拥有 20 年经验。对于原型或小批量生产,请比较我们的冲压工艺与原型金属冲压与 CNC 加工对比,看看哪种更适合您的时间安排。如果您正在设计配套外壳,二次加工 CNC 刀具选择指南具有相关性;如需 Ra 0.8µm 以外的表面处理,请参阅CNC 加工公差指南,了解电镀和钝化选项。

将您的图纸或零件号 1 2605131s210f6 发送至 sc@bquq.com,我们将在 12 小时内返回正式报价——如果您需要定制版本,包括模具摊销费用。如有即时问题,请通过 WhatsApp 联系 +86 13713157787。无起订量,无最低订购要求,只为您的确切数量提供精准价格。
