Abstract
An electrical connector includes an insulative housing (3), a number of contacts (4) retained in the insulative housing (3) and a metallic shell (1) enclosing the insulative housing (3). The metallic shell (1) includes a number of peripheral walls and a soldering tab (15) extending therefrom. Each of the soldering tab (15) and the peripheral walls includes an intermediate layer (20), a first plating layer (21), a second plating layer (22) and a third plating layer (23). The third plating layer (23) covers both inner and outer sides of the second plating layer (22) of the peripheral walls for enhancing anti-wear properties while leaving the second plating layer (22) of the soldering tab (15) uncoated for wetting. Besides, a method of surface treatment of the metallic shell (1) is also disclosed.
