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.

There is provided a coaxial connector device that enables a reduction in deterioration in signal quality and transmission characteristics at high frequencies. A coaxial connector device 1 includes a main connector 10 and a board connector 20. A main connector body 11 has a first fitting part R1 for a coaxial cable connector at one end and a second fitting part R2 at the other end. Inside the main connector body 11, a center contact 13 and a card edge substrate 17 electrically connected to the center contact 13 are included. In a board connector body 21 a slot 23 is formed. When the second fitting part R2 of the main connector 10 is fitted to the board connector 20, the end portion of the card edge substrate 17 is coupled to the slot 23 of the board connector body 21, a plurality of substrate contacts included in the card edge substrate 17 electrically contacts a plurality of inner contacts 25 of the board connector body 21, and the second fitting part R2 of the main connector body 11 electrically contacts an outer conductor contact 27.

A connector includes: a plurality of conductors; a magnetic core; a housing; and an insulator that locates a core assembling portion therein, the core assembling portion being composed of the respective intermediate portions of the plurality of conductors and the magnetic core, the housing chamber is at least partitioned into a first space in which the core assembling portion is housed and a second space in which the first electrical connection portion and the first counterpart conductor side are housed and are physically and electrically connected to each other, and the insulator is a solidified material of a liquid insulating potting agent filled in the vicinity of the core assembling portion in the first space in order to cover the core assembling portion.

A drive element for an electrical connector comprises a gear wheel and an overload coupler. The overload coupler is between the gear wheel and a hub.

Embodiments discussed herein refer to connectors that enable two structures or devices to be coupled together in a manner that enables consistent and reliable operation of contactless communications and power transfer. The connector integrates power and alignment such that when two connectors are coupled together the power connections are also responsible for connector alignment. The connector alignment ensures that contactless communication channels, spanning between the connectors, are aligned to enable consistent and reliable operation of contactless communications.

An electronic component unit includes: a circuit board to mount an electronic component on the circuit board; a connector to receive and retain a terminal to be electrically connected to the circuit board; and a cover assembled to the connector and housing the circuit board. The circuit board is retained with the cover by using a beard retaining portion integrated with or separate from the cover. The connector has a cover retaining portion including a pair of protrusion portions. The cover retaining portion retains the cover assembled to the connector by holding a part of the cover between the pair of the protrusion portions.

A connector including a contact element arranged in an interior of the connector and contacting an electrical connection element and an impedance improving element located at a side of the electrical connection element. The impedance improving element has a reception channel through which the contact element extends and a deformation section adapted to be deformed at least one of radially and axially.

A cable connection element for reducing signal transmission loss includes a front clad, a base and a connection terminal. The connection terminal has a first core-holding portion formed on a front end thereof, a second core-holding portion formed on a rear end thereof, a core-clamping portion formed between the first and second core-holding portions, and a pin formed on a rear end of the second core-holding portion. The second core-holding portion is fixed inside the base. The front clad is connected with the base to enclose the first core-holding portion therein. When a core of a cable penetrates the front clad, the core is held by the core-clamping portion and is electrically connected therewith, such that signals from the core can be transmitted to the pin through the core-clamping portion and the second core-holding portion. Accordingly, signal transmission loss arising from capacitance effect can be improved.

A connector includes: a plurality of conductors; a magnetic core; a housing; and an insulator that locates a core assembling portion therein, the core assembling portion being composed of the respective intermediate portions of the plurality of conductors and the magnetic core, the housing chamber is at least partitioned into a first space in which the core assembling portion is housed and a second space in which the first electrical connection portion and the first counterpart conductor side are housed and are physically and electrically connected to each other, and the insulator is a solidified material of a liquid insulating potting agent filled in the vicinity of the core assembling portion in the first space in order to cover the core assembling portion.

One of more panels of the cabinet include at least one conductive region that is optionally covered by an insulative covering. These conductive regions are coupled to an external power source. Shelves, drawers, other cabinet components, electrical devices in a cabinet (including, but not limited to, a motor, lights, outlet, appliance, sensor, processor, etc.), and the like can further conduct or receive electrical energy by electrically coupling to the conductive regions within the panels of the cabinet, for example, through shelf pins that are inserted into holes in the panels.
