A connector for being arranged at an end of an electric wire includes a housing including an electric wire supporting portion in which an insertion hole to insert the electric wire thereinto is formed and which is harder than the electric wire and sandwiches the electric wire inserted into the insertion hole, and an annular magnetic core including a nanocrystalline soft magnetic material which is arranged around the electric wire supporting portion.

Embodiments of the present disclosure provide techniques and configurations for a cable assembly for single wire communications (SWC). In one instance, the cable assembly may comprise a wire having a wire end to couple with a signal launcher of an electronic device, and a first cover portion to house a first portion of the wire that extends from the wire end. The first cover portion may comprise a shape to conform to a shape of the signal launcher, and may be fabricated of a material with a dielectric constant above a threshold. The assembly may further comprise a second cover portion coupled with the first cover portion to house a second portion of the wire that extends from the first wire portion and protrudes from the first cover portion. The second cover portion may be fabricated of a ferrite material. Other embodiments may be described and/or claimed.

Provided is a joint connector having excellent workability. A joint connector (1) comprises a housing (10) having a plurality of lances (13), a plurality of terminal fittings (30) which are inserted into the housing (10) from the rear of the housing (10), and which are locked by means of a locking action of the plurality of lances (13), joint terminals (50) which are attached to the housing (10) from the front, and which allow the plurality of terminal fittings (30) to conduct electricity, and a holding member (80) which holds the joint terminals (50) and which is attached to the housing (10) so as to cover a front surface of the housing (10), wherein: a jig insertion chamber (16) which opens in a rear surface of the housing (10) is formed in the housing (10); and the lances each (13) have a jig contacting portion (13A) disposed inside the jig insertion chamber (16).

An electrical connector for a multi-wire electrical cable includes at least two cable-side electrical contact elements including associated terminals to each of which is connected a wire of the electrical cable, and at least two output-side electrical contact elements, from each of which projects an electrical connector element by which a mating connector is electrically connectable. A tubular outer conductor extends along a longitudinal direction from a cable-side end to an output-side end and encloses the cable-side and output-side contact elements. At least one stranded drain wire of the electrical cable contacts a shield of the electrical cable and is guided to the electrical connector separately from the wires of the electrical cable. The outer conductor has at least one second slot extending along the longitudinal direction of the outer conductor, and the drain wire is received in the second slot in the outer conductor.

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, as well as two output-side electrical contact elements, from each of which projects an electrical connector element by which an electrical connection can be established to a mating connector. A carrier body is disposed between the cable-side contact elements and the output-side contact elements. The carrier body forms a support region which extends from a first connecting section to a second connecting section and with which both the cable-side and the output-side contact elements are in connection. At each of the two connecting sections, a respective supporting section of the carrier body extends from the support region in such a way that the support region and the two supporting sections form a ring-shaped circumferential structure.

A filter assembly for a high-voltage connector is disclosed. The filter assembly has a first and a second bus bar, a filter circuit disposed on a circuit carrier, a ring core, and a filter housing. Each bus bar has a first terminal section, a second terminal section, and a connecting section between the first terminal section and the second terminal section. The filter circuit, the ring core, and at least a part of the first and second bus bars are disposed in the filter housing. The first and second bus bars extend substantially parallel to each other and through the ring core. The circuit carrier is disposed in a region of the filter housing in which the connecting section of each of the first and second bus bars is accommodated.
