Abstract: A printed circuit (PC) tail contact includes a low-force, high mating durability, open-ended, compliant portion. The PC tail contact is structured with a contact portion to mate with a corresponding contact of another connector, a shoulder portion coupled to the contact portion to position the PC tail contact within the insulator of the PCB connector, a tail portion coupled to the shoulder portion, and the compliant portion coupled to the tail portion. The compliant portion may include two, three, or four deflectors with an open slit based on one or more of an internal diameter of a PCB through-hole or a current to be carried by the PC tail contact.

Abstract: A modular interconnect system is described for high-speed applications. Low speed signal pins including power, ground, and other low frequency communications may be combined in a first connector while high speed signal pins may be provided in one or more separate connectors with the wiring bundled together. Each connector and associated wiring may have separate shielding. The high-speed connectors may include differential or single-ended signal pins. The high-speed connectors may also include a mechanical polarity indicator such as a protrusion.

Abstract: A coupling can include a barrel that includes a communication pathway, such as an electrical contact or optical pathway. The coupling can include a nut that is configured to engage with a corresponding portion of a mating connector, such as via a threaded connection. When the coupling and the mating connector are engaged, the nut secures the coupling and the mating connector together, and respective termination elements of the coupling and the mating connector are in communication with each other. The coupling can include a torque-limiting mechanism. The torque-limiting mechanism can be configured to enable the transmission of torque up to a limit amount, and to inhibit or prevent the transmission of torque above the limit amount.

Abstract: A retaining wave spring includes a first open-loop that has a wall that is substantially planar. The retaining wave spring also includes a second open-loop continuing from an end portion of the first open-loop. The second open-loop has a wall having curved portions. An outer diameter of the first open-loop and an outer diameter of the second open-loop have different sizes.
