Abstract
用于电插塞连接器(10)的导电壳体部件(11，12，13)由具有表面层结构且由铝或铝化合物形成的本体(16，17，18)形成，作为层结构，顺序设置化学镀镍形式的粘接层、防腐蚀保护层，以及金属钝化层。为了避免在这种壳体部件中使用有毒金属和它们的化合物并确保足够的导电性和抗腐蚀性，防腐蚀保护层由锌-钴-铁化合物形成，钝化层由三价铬形成的化合物构成，由包含硅酸盐的有机化合物形成的密封层被用作外层。
Description
技术领域
本发明涉及一种导电零件，尤其涉及一种根据权利要求1前序部分的、用于电插塞连接器的壳体部件。
背景技术
在目前公知的用于电插塞连接器的导电壳体部件中，镉被用作防腐蚀保护层，而包含六价铬(Cr6+)的化合物被用作钝化层(passivation layer)。这种层结构确保了必须的导电性，使得壳体部件起到例如电屏蔽的作用，并且对于环境影响具有足够的抗腐蚀能力。此外，这种壳体部件所遇到的缺陷(具体在它们的层结构中)在于镉有很强的毒性，并且，由包含六价铬制成的化合物是致癌的。
鉴于上述原因，已经决定禁止将这种有害物质用于生产电气和电子零件。因此，欧盟环保指令(RoHs)在2006年7月1日进入强制执行，据此，如无异议，有毒金属例如铅、镉、六价铬等可能不能用于生产电气电子设备。
发明内容
因此，本发明的目的是描述一种上述类型的导电零件，尤其是用于电插塞连接器的壳体部件，其避免使用上述金属和它们的化合物，但是其又具有足够的导电性和抗腐蚀性。
为了实现上述类型的导电零件，尤其是电插塞连接器的壳体部件，提供了权利要求1表述的特征。
本发明中描述的方法的结果是根据欧盟环保指令，不能使用有毒金属，其要用无毒金属代替，并且零件必须保持相同级别的导电性和抗腐蚀性。另外，由于层的顺序而得到了更好的耐温性。最终层(即密封层)除了提供希望的抗腐蚀性外，还确保了有利的滑动特性，并防止当插塞时和去除插塞时可能在表面上产生凹坑。
在根据权利要求2的特征的基础上，可有利地实现下述方面：首先，通过顺序施加钝化层可以是三价铬化合物，其次，钝化层可确保零件表面的希望的黑色外表。
其它有利的实施例可由权利要求3至7的其中之一或多个特征获得。
通过下面的优选示例性实施例可清楚本发明的进一步细节。
附图说明
图1以透视图方式表示导电零件，其示出了一个电插塞连接器的三个壳体部件。
具体实施方式
这里，在图中只是部分示出的插塞连接器具有三个壳体部件11、12和13，其中，壳体部件11包括多个承插式插塞(未示出)，另一壳体部件12包括多个以类插塞(plug-like)方式插入第一壳体部件11中的插入式插塞(也未示出)。第三壳体部件13具有固定螺母的形状，其将插入到第一壳体部件11中的另一壳体部件12固定到第一壳体部件11的插旋接头中。第二壳体部件12在围绕插入式插塞的区域中具有接触轮缘15，接触轮缘15具有弹性作用的接触突片以实现第二壳体部件12在第一壳体部件11内的导电连接。连接至承插式插塞和插入式插塞的相应的电缆没有被示出，也没有示出它们相对于外部密封的安装件。
第一壳体部件11和第二壳体部件12(不包括接触轮缘15)以及第三壳体部件13由这样的材料制成，即，所述材料不但具有机械强度而且具有足够的导电性以屏蔽插塞接触连接，而且抗腐蚀性适于适应在户外条件差的操作过程中碰到的环境影响。在已经实施或即将实施的欧盟环保指令的基础上，通过本发明利用符合上述指令的金属材料，即对人体无毒或无害的金属材料实现了上述目的。
所有的壳体部件11、12和13被以相同的方式设计。壳体部件11、12和13具有本体16、17或18，每个本体具有其自己的几何形状，并且每个本体是由铝或合适的铝合金制成的模铸部件。
然后，本体16、17、18被进行化学镀镍，优选没有镉或铅，并且本体16、17、18以这种方式涂覆作为粘接层的化学镀镍层，其中粘接层的厚度在5至8μm的范围内。
厚度在5至13μm范围内的后续层由作为高碱性电解液的锌-钴(ZnCo)化合物形成，以构成防腐蚀保护层。锌-钴-铁化合物包含比例在0.7-1％范围内的金属钴/铁。钴/铁的这个比例用于通过又一层实现后续的钝化以及实现壳体部件11、12和13的优选的黑色外部颜色。因此，增加了抗腐蚀保护。
在锌-钴-铁层的顶部设置由铬-III化合物形成的钝化层。这一由无银、黑色钝化层以及基于三价铬的化合物形成的层具有在0.5至1μm范围内的厚度。
为了使该层结构具有恰当和希望的抗腐蚀性以及在插塞过程和去除插塞过程中具有滑动特性，即，当壳体部件11、12或13被插入或去除时，厚度的数量级为0.01至0.02μm的密封层被设置作为上述层结构的外层。该密封层由含有无机硅酸盐的化合物形成。
如上所述，壳体部件11、12和13在终饰中为暗色的、大致黑色的外部颜色。
机械耐用性测试显示了足够的机械强度和一致的电屏蔽能力。涉及利用盐溶液喷射所讨论的零件的腐蚀测试没有产生任何将对电子和机械特性产生不利影响的因素。
