A hybrid optical and electrical connection system includes a connectorized pigtail and a closure. The connectorized pigtail includes: a) a stub cable including a jacket containing at least one optical fiber and at least two electrical conductors, the stub cable having opposite first and second ends; and b) a hybrid optical and electrical connector that is factory terminated at the first end of the stub cable. The closure mounts at the second end of the stub cable for enclosing optical and electrical connections between the second end of the stub cable and a field cable.

A connection terminal is provided and includes a body, a welding pin, a first stop, a second stop, and a third stop. The body includes a pair of planar surfaces and a pair of side surfaces. The welding pin extends from an end of the body. The first stop extends outwardly from one of the pair of side surfaces, while the second stop extends outwardly from another of the pair of side surfaces. The third stop protrudes outwardly from one of pair of planar surfaces.

An extension cord system includes an electronic device that may store audio data. A case is provided and the electronic device is removably positioned therein. A pair of headphones is provided. The headphones are selectively electrically coupled to the electronic device. An extension cord is selectively electrically coupled between the electronic device and the pair of headphones. The extension cord engages the case when the extension cord is electrically coupled to the electronic device. Thus, the extension cord is inhibited from being unplugged from the electronic device.

An electrical connector for a multi-wire electrical cable includes two cable-side electrical contact elements including associated terminals to each of which is to be connected a wire of the electrical cable, and two output-side electrical contact elements which are spaced apart from the cable-side electrical contact elements and from each of which projects an electrical connector element via which an electrical connection can be established to a mating connector. An active electrical device is disposed between the cable-side contact elements and the output-side contact elements. The active electrical device is placed on the contact elements, such that the active electrical device is in electrical contact with each of the contact elements, and such that the cable-side contact elements and the output-side contact elements are electrically connected to each other. The output-side contact elements are separated and axially spaced apart from the cable-side contact elements.

An electrical power tap connector for a model vehicle is provided including a first power tap housing. The first power tap housing contains a power tap terminal configured to electrically couple with a connector terminal of an electrical connector. The power tap connector also includes a second power tap housing releasably securable to the first power tap housing and a releasable locking mechanism configured to physically secure the power tap connector to the electrical connector. Wherein the power tap terminal is configured to electrically couple with the connector terminal via a non-mating end of the electrical connector.

A wire harness includes a cable constituted of a plurality of electric wires bundled together so as to include a plurality of cable ends and a plurality of connectors mounted one-to-one on the plurality of cable ends, wherein each of the plurality of connectors includes a connector terminal connected to an end of the electric wire, a tubular housing body accommodating the connector terminal, and a flange formed to project from an outer circumferential surface of the housing body. On a fitting side for fitting with a mating connector, the flange has a rugged shape that differs between the plurality of connectors.

A power adapter and an electronic device assembly including the power adapter are provided. The power adapter includes an adapter body, prongs, and a cover. The adapter body has a first end surface. The prongs are exposed at the first end surface of the adapter body. The cover is movably connected with the adapter body, and the cover has a second end surface. When the cover is in a closed state, the prongs are covered, and the second end surface is away from the adapter body. When the cover is in an open state, the first end surface and the second end surface cooperatively form a plugging surface of the power adapter.
