Plating method for processing electrical connector

1 . A method of plating a metallic layer over an outer surface of a barrel of a RF connector, comprising the steps of:

1) providing a barrel having an internal chamber and an outer surface;

2) inserting a insulative member into the chamber masking the internal surface of the barrel; and

3) applying a metallic layer over the outer surface.

2 . A plating method as claimed in claim 1 , wherein said barrel has an operating portion and an annular portion extending from the operating portion, the operating portion and the annular portion are made from metal material and molded as a whole.

3 . A plating method as claimed in claim 2 , wherein said barrel is made from brass-zinc alloy material.

4 . A plating method for applying a layer of metal to an electrical connector comprising the steps of:

providing a barrel defining an internal room and an insulative member;

inserting the insulative member into the internal room of the barrel and having the insulative member firmly resist against an inner surface of the barrel; and

plating a layer of metal around an outer surface of the barrel.

5 . A plating method as claimed in claim 4 , wherein said electrical connector is an RF (Radio Frequency) electrical connector.

6 . A plating method as claimed in claim 4 , wherein said barrel has an operating portion and an annular portion extending from the operating portion, the operating portion and the annular portion are made from metal material and molded as a whole.

7 . A plating method as claimed in claim 6 , wherein said barrel is made from brass-zinc alloy material.

8 . A plating method as claimed in claim 4 , wherein said insulative member comprises an axial bore for receiving a central terminal.
