Abstract: An electrical connector for transformer studs accommodates two different size transformer studs in the same slip-fit blind hole. The hole is provided with circumferential arc recesses which are sized and threaded to match the threads on the two different size studs. One or more jam screws force the stud into the respective recesses, and the matching threads provide a substantial contact area and an effective and efficient long lasting and sturdy electrical transformer connection.

Abstract: Shielding of electrical wires from radiated energy and lightning is critical to protecting the integrity of electronic components. A shield termination electrical connector assembly uses a termination adapter having elongated termination holes and feed channels leading into the termination holes to facilitate the process of guiding the shields into the proper termination slots. Moreover, flexible braided wires may be connected to the shields and terminated in the termination adapter. These flexible braided wires are compressed in the termination adapter instead of the shields, thus preventing damage to the shields to ensure their functionality.
