采用热塑管包封法、涂料绝缘法、仿形夹具法等保护方法对几种形状由简单到复杂的连接器进行局部电镀金。对于结构简单的零件，采用单一保护方法即可达到局部电镀金的目的；但对于结构比较复杂或要求比较严格的零件，需多种保护方法联合使用才能达到良好的局部保护效果。
Some protection methods including encapsulation with thermoplastic hose, coating insulation, imitating jig, and etc. were applied to partial gold plating of several connectors with simple and complex shapes. The partial gold plating can be accomplished by using single protection method for the simple-structured parts, but needs a combination of various protection methods for the parts with complex structure or strict requirements.
