缠绕连接处理用金合金丝的卷筒
摘要：
本发明公开了一种卷筒，其包括主体和铬层。主体整体地包括管状的第一部分和环状的第二部分。主体使用塑料形成。第二部分设置在第一部分的两侧。铬层镀在主体上。铬层具有大约0.1微米至大约100微米的均匀的厚度。金合金丝缠绕在铬层上。铬层具有光滑表面。卷筒与连接装置相结合，使得卷筒可将连接装置与缠绕在铬层上的金合金丝电连接。根据本发明的实施例，外部撞击不容易改变卷筒的形状。此外，当金合金丝缠绕在卷筒上时，不会在卷筒上形成划痕。而且，形成卷筒所需成本相对较低，使得卷筒能够作为耗材使用，无需回收。
摘要（英）：

A spool includes a body and a chromium layer. The body integrally includes a first portion having an annular shape and a second portion having a tubular shape. The body is formed using plastic. The first portion is provided on both sides of the second portion. The chromium layer is plated on the body. The chromium layer has a uniform thickness of about 0.1 mum to about 100 mum. A gold alloy wire is wound on the chromium layer. The chromium layer has a glossy surface. The spool is combined with a bonding device such that the spool electrically connects the bonding device to the gold alloy wirewound on the chromium layer. The shape of the spool is not easily changed by an external impact. When the gold alloy wire is wound on the spool, a scratch is not formed on the spool. Furthermore, thecost required for forming the spool is relatively small so that the spool may be used as an expendable supply. As a result, a recycling process is not required.
