Description

一种电连接器波纹弹片表面处理方法
技术领域
本发明属于电连接器配件生产工艺技术领域,尤其涉及一种电连接器波纹弹片表面处理方法。
背景技术
在各类电子仪器、仪表或电子设备中广泛应用大量的电连接器,常见的电连接器一般包括连接器公头和连接器母头,为了保证电连接器使相互连接的两个电气元件之间的电性连接可靠和牢固,通常在连接器公头或连接器母头上需要套装相应的弹性元件,以增加电连接器的预紧力,弹性元件的主视图和俯视图如图1、图2所示,常采用薄钢带制成设有缺口的环形形状,现有的波纹弹片在成型加工后需要进行抛光、钝化等工序处理,现有的抛光工序能够显著改善波纹弹片的表面外观,然而,从微观来看,抛光会在波纹弹片表面残留相应的抛光痕,使波纹弹片厚度减薄,并且波纹弹片在先经过抛光后再经过钝化处理,容易使钝化剂残留在抛光痕内,致使波纹弹片刚度提高,而抗腐蚀性降低,弹性下降,致使波纹弹片提供给连接器公头与连接器母头之间的连接预紧力降低,影响了电连接器的电气可靠性。
发明内容
为解决上述技术问题,本发明提供了一种电连接器波纹弹片表面处理方法。
本发明通过以下技术方案得以实现。

硅烷偶联剂;1-2份;
双氧水:15-20份;
缓蚀剂:1-4份;
纳米二氧化钛:2-4份,其粒径为50-100nm;
偏钒酸铵:2-3份;
水:140-180份。
所述钝化剂还包括3-6份钼酸钠。
所述缓蚀剂为月桂酰肌氨酸。
所述缓蚀剂还包括羟基乙叉二膦酸,所述羟基乙叉二膦酸和月桂酰肌氨酸的质量份数之比为4:5。
所述波纹弹片的材质是牌号为:“0Cr17Ni7Al”的不锈钢钢带。
所述不锈钢钢带厚度为0.2mm至0.4mm。
本发明的有益效果在于:采用本发明的技术方案,使波纹弹片在不经过抛光处理后直接进行钝化处理,避免在波纹弹片表面形成抛光痕,也防止波纹弹片因此而厚度减薄,从而防止波纹弹片在钝化处理时,钝化剂残留在抛光痕内,使波纹弹片具有足够的弹性,使波纹弹片在装配后,提供给连接器公头与连接器母头之间足够的连接预紧力,保证了电连接器的电气可靠性,此外,在钝化剂中添加了适量的柠檬酸和缓蚀剂等组分,在波纹弹片具有足够弹力的同时,大大提高了其抗腐蚀性能。

具体实施方式
下面进一步描述本发明的技术方案,但要求保护的范围并不局限于所述。
如图1、图2所示,本发明提供一种电连接器波纹弹片表面处理方法,包括以下步骤:
将经过成型加工阶段获得的波纹弹片1浸入钝化剂中持续钝化处理25min至40min后取出,用清水冲洗净、擦干,所述成型加工与钝化处理间隔时间不超过30min。
进一步地,所述钝化处理过程中,控制所述钝化剂温度为50℃至70℃。
另外,所述钝化剂包括以下组分按照相应的质量份数均匀拌合而成:
硝酸:20-30份;
硫酸:5-10份;
氢氟酸:2-4份;
柠檬酸:2-4份;
硅烷偶联剂;1-2份;
双氧水:15-20份;
缓蚀剂:1-4份;
纳米二氧化钛:2-4份,其粒径为50-100nm;
偏钒酸铵:2-3份;
水:140-180份。
优选所述钝化剂还包括3-6份钼酸钠。所述缓蚀剂为月桂酰肌氨酸。所述缓蚀剂还包括羟基乙叉二膦酸,所述羟基乙叉二膦酸和月桂酰肌氨酸的质量份数之比为4:5。所述波纹弹片1的材质是牌号为:“0Cr17Ni7Al”的不锈钢钢带。所述不锈钢钢带厚度为0.2mm至0.4mm。
对采用厚度为0.3mm的不锈钢钢带制成的波纹弹片,分别按照现有工艺和本发明提供的工艺方法进行处理后,实测数据如下:
表1厚度为0.3mm的不锈钢波纹弹簧实测数据
处理工艺 厚度 预紧连接力 分离力
先抛光再钝化 0.26 0.485N/m 0.44N/m
直接钝化 0.3 0.63N/m 0.59N/m
直接钝化 0.3 0.58N/m 0.56N/m
从实测结果来看,抛光工序对波纹弹片厚度尺寸的影响很大,对连接器预紧力的影响也很大,因此,采用本发明提供的技术方案,使波纹弹片在不经过抛光处理后直接进行钝化处理,避免在波纹弹片表面形成抛光痕,也防止波纹弹片因此而厚度减薄,从而防止波纹弹片在钝化处理时,钝化剂残留在抛光痕内,使波纹弹片具有足够的弹性,使波纹弹片在装配后,提供给连接器公头与连接器母头之间足够的连接预紧力,保证了电连接器的电气可靠性,此外,在钝化剂中添加了适量的柠檬酸和缓蚀剂等组分,在波纹弹片具有足够弹力的同时,大大提高了其抗腐蚀性能。
