Integrated high frequency connector
High-speed connectors that save space in an electronic device, are simple to connect, and are readily manufactured. One example can provide a high-speed connector having high-speed connections. The high-speed connections can be integrated with low-speed connections in a board-to-board structure to save space in an electronic device. An example can provide high-speed connections that are simple to connect. The board-to-board structure can include a board-to-board plug, where each high-speed connection includes a high-speed contact having a lateral portion. The lateral portion can include right-angle tabs to guide a central conductor of a coaxial cable. The central conductor of each coaxial cable can be soldered to a corresponding lateral portion. Ground contacts for the board-to-board plug can include crimping portions to connect to an outer shield of each coaxial cable. These high-speed connectors can be readily manufactured by utilizing stamped contacts and molded housings.
