A plug connector capable of increasing the sealing between a rubber member and an outer circumferential surface of a spark plug insulator for improvement in current leakage resistance. The plug connector includes a conductive part that electrically connects a spark plug and a power supply member for power supply to the spark plug; and a rubber member that covers the conductive part. The spark plug has an insulator and a terminal electrode protruding toward the rear from a rear end of the insulator. The plug connector further includes a ring member arranged on an outer circumference of the rubber member.

An electrical connector arrangement comprises a metal mounting bracket for securing the arrangement to a structure; an electrically insulating mounting block abutting the mounting bracket; a clamp to secure an electrical cable to the mounting block, the electrical cable comprising a plurality of electrical conductors; and a plurality of spaced-apart terminals to accommodate the respective electrical conductors.

A terminal unit includes inner conductors (35) fixed to front ends of wires (38). A dielectric (10) has a holding member (11) and a cover (27) united in a direction intersecting an axial direction of the wires (38) and accommodates the inner conductors (35). Guide recesses (17) are formed on the holding member (11) and extend in a front-rear direction. Guide ribs (33) are formed on the cover (27) and can slide in contact with the guide recesses (17) to allow relative displacement of the holding member (11) and the cover (27) in the front-rear direction while keeping the holding member (11) and the cover (27) united. Guides (19) bring the holding member (11) and the cover (27) closer together in a uniting direction while displacing the cover (27) from a temporary assembled position to a proper assembled position in the front-rear direction.

An electric cable includes at least one current line having first and second ends, including several wires, a first plug connector and at least one second plug connector arranged on the first and second ends, respectively. At least one plug connector includes a material having A) 98.0% to 99.8% by weight of a polymer selected from the group consisting of polyurethane (PU), styrene-butadiene block copolymers (SBS), perfluorocarbons and mixtures thereof, and B) 0.2% to 2.0% by weight additives. The total of components A and B results in 100% by weight. A first connection nut and at least one second connection nut are arranged on the first and second plug connectors, respectively. At least one light source is arranged in a first plug connector and/or in a second plug connector and is configured in order to be supplied with electrical energy by at least one wire of the current line.

A receptacle connector defines a port. The port is provided with spring fingers that are configured to engage a mating module. The spring fingers are thermally coupled to a heat transfer plate that can be configured to provide part of a cage that defines the port. Fins can be mounted on or integrated into the heat transfer plate. In operation, thermal energy from an inserted module is transferred from the module to spring fingers and then to the heat transfer plate and then to a thermal dissipation system.
