Abstract: Connectors for use with high-speed signals. Mating connectors may include interlocking components that control the mated position of the connectors such that wipe distance can be reduced. These components may be compact such that they can be integrated into connectors with standardized exterior dimensions. They may be integrated into mating guides of the mating connectors. For one of the mating connectors, such a component may be a locking member disposed in and curving out of its guide such that the locking member mates with a matching feature of a component in the guide of the other connector. As the connectors are secured by these components, the conductive elements may be shorter than the lengths required by standards, which reduces the stub and therefore increases signal integrity. Such a configuration provides higher signal integrity at higher speeds, while conforming to standards that constrain mating and mounting interfaces.

Abstract: A connector for use with high-speed signals. The connector includes a connector subassembly having conductors disposed in groups and a shielding shell at least partially encircling each group. Each conductor includes a mating end and a mounting end opposite the mating end. The shielding shell includes openings that expose contact surfaces of the conductors at the ends. The shielding shell is formed by attaching a second shell part to a first shell part. The first shell part has plateaus and valleys, and the second shell part is attached to the first shell part at the valleys, such that tubular structures are formed. The shielding shell includes contact surfaces disposed on the same planes with the contact surfaces of the conductors at the ends, respectively. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.
