Abstract
An apparatus comprising a direct board-to-board coaxial connection fabricated from metal parts that have been stamped and formed is disclosed. The connection allows direct board-to-board coaxial connections with a low cost and ease of manufacturing.
Claims30
An apparatus comprising:
- a combination digital signal and radio frequency connector for directly coupling a motherboard to a radio frequency module board.
An apparatus comprising:
- a radio frequency board having a combination digital signal and radio frequency connector adapted for directly coupling to a motherboard for a computer.
An apparatus comprising:
- a pin and receptacle connection for transferring a signal coupled between a radio frequency module compatible with a mobile computer motherboard and a motherboard in a mobile computer;
- and
- a spring cage and barrel connection coupled around the pin and receptacle connection for transferring ground, wherein the apparatus comprises a radio frequency coaxial direct board to board connection.
An apparatus comprising:
- a direct board to board coaxial connection having a male portion and a female portion, wherein one of the male portion or female portion is coupled to a computer motherboard and the other of the male portion or female portion is coupled to a radio frequency module card such that the radio frequency module card is removeably coupled to the computer motherboard by the direct board to board coaxial connection.
A method comprising:
- forming a signal pin;
- stamping a ground shield spring cage from a sheet of metal;
- rolling the ground shield spring cage to form a cage with finger springs for gripping the inside of a ground barrel;
- stamping a ground barrel from a sheet of metal;
- rolling the ground barrel into a cylinder;
- stamping a signal pin receptacle from a sheet of metal;
- rolling the signal pin receptacle to form a cylinder with a spring end that resembles a tulip;
- plating the pin and the barrel;
- assembling the signal pin, ground spring cage, and a housing to form a male coaxial connector by press interference fitting;
- and
- assembling the signal pin receptacle, ground barrel and a housing to form a female coaxial connector by press interference fitting.
