Patent ID: 8512047

Claim:
A rotatable coaxial adaptor for linking high frequency coaxial cables comprising: a first mounting block including a first receiving space formed inside the first mounting block and having an open rear; a top surface; and a top opening formed in the top surface of the first mounting block and communicating with the first receiving space; a first stationary insulator mounted in the first receiving space of the first mounting block; a first stationary contact pin made of an electrically conductive material and mounted through the first stationary insulator; a first bearing mounted in the first receiving space of the first mounting block; a first rotary part rotatably mounted through the first bearing and including a first rotary insulator and a first joining tube; a first rotary contact pin made of an electrically conductive material, mounted through the first rotary insulator, rotatably connected to the first stationary contact pin and including a rear end surface; and a contact recess formed in the rear end surface of the first rotary contact pin; a connecting sleeve secured to the top opening of the first mounting block at a bottom end; a second stationary insulator mounted in the connecting sleeve; a second stationary contact pin made of an electrically conductive material, mounted through the second stationary insulator and connected to the first stationary contact pin; a second bearing mounted around the connecting sleeve; a second mounting block rotatably mounted around the second bearing and including a second receiving space formed inside the second mounting block and having an open front; a bottom surface; a bottom opening formed in the bottom surface of the second mounting block and communicating with the second receiving space, and a top end of the connecting sleeve and the second bearing received in the bottom opening; and a second joining tube formed on the open front of the second receiving space; a second rotary insulator mounted in the second receiving space of the second mounting block; and a second rotary contact pin made of an electrically conductive material, mounted through the second rotary insulator and rotatably connected to the second stationary contact pin.
