A semiconductor device includes: a plate-shaped terminal including one main surface and another main surface and having one end electrically connected to a semiconductor chip; a nut arranged on the one main surface side at another end of the terminal; a nut cover provided on the one main surface side at the other end of the terminal and configured to cover the nut; and a case configured to surround the semiconductor chip and integrate the terminal and the nut cover, wherein the nut cover includes a protruding portion protruding from a lower portion of the nut cover to the one end side of the terminal.

A three-dimensional (3D) printed electrical connector includes an insert component, at least a first sealing member, and a shell. The insert component includes a body adapted for 3D printing. The body has first and second ends and includes a cavity penetrating the body along a longitudinal axis of the body. The first sealing member is associated with the insert component and is adapted for 3D printing. The shell at least partially encloses the insert component.

An electrical connector is presented herein. The electrical connector includes an insulator that is formed of a dielectric material and defines a cavity extending therethrough. The cavity has a plurality of cylindrical sections. A first cylindrical section of the plurality of cylindrical sections has a diameter that is larger than a diameter of adjoining second and third cylindrical sections of the plurality of cylindrical sections on each side of the first cylindrical section. The insulator is preferably formed using an additive manufacturing process, such as stereolithography, digital light processing, fused deposition modeling, fused filament fabrication, selective laser sintering, selecting heat sintering, multi-jet modeling, multi-jet fusion, electronic beam melting, laminated object manufacturing, or 3D printing.

A method of manufacturing an electrical connector including the steps of: insert-molding a base portion around a shielding plate to form two rows of passageways exposing outwardly and rearwardly; over-molding an insulative housing at a rear of the base portion; and inserting two rows of terminals through the insulative housing to the two rows of passageways, respectively.

A grounding system for electrically connecting a first component to a second component. A connection plate has a hole and is configured to be in electrical contact with the first component. A receptacle plate is in electrical contact with the connection plate, and has a receptacle opening aligned with and larger than the hole. A pin has a first end configured to be electrically connected to the second component and an opposed second end receivable through the receptacle opening and through the hole. An electrical connector is retained in electrical contact with the pin. The electrical connector is movable along the pin and biased toward the second end, receivable in the receptacle opening and configured to be in electrical contact with a circumferential surface of the receptacle opening, and has an outer dimension greater than that of the hole so as to be prevented from passing therethrough.
