A contact element assembly for a plug connector part which is connectable in a plug-fitting manner to a mating plug connector part includes: a contact element which has a contact section for making electrical contact with a mating contact element, and a connecting section for producing a crimp connection with an electrical line connectable to the contact element. The connecting section is made of a copper alloy and has an opening for receiving the line and a circumferential surface delimiting the opening. The connecting section has a surface structure which is formed on the circumferential surface and operatively connects to the electrical line upon producing the crimp connection by reshaping the connecting section.

A connector includes an insulator, a plurality of pairs of terminals provided on the insulator, and a resistance element. The plurality of pairs of terminals include at least one pair of cable terminals electrically connected with a cable and at least one pair of vacant terminals that are unused. The resistance element is electrically connected between each pair of vacant terminals.

It is aimed to reduce friction resistance generated in a resilient contact portion. A shield connector is provided with a dielectric for accommodating an inner conductor, a tubular outer conductor for surrounding the dielectric, a resilient contact portion formed in the outer conductor, and a cut portion formed in the outer conductor and enabling a supporting portion supporting the resilient contact portion, out of the outer conductor, to be resiliently deformed. If the resilient contact portion contacts a mating outer conductor and is resiliently deformed, the supporting portion supporting the resilient contact portion is resiliently deformed by a reaction force from the mating outer conductor. Since a resilient deformation amount of the resilient contact portion is reduced by as much as the supporting portion is resiliently deformed, friction resistance generated in the resilient contact portion is reduced.

A single element electrical connector includes a single conductive contact element formed into a cage structure having a wire insert end and a wire contact end along a longitudinal centerline axis of the connector. The cage structure defines an upper pick-up surface having a surface area suitable for placement of a suction nozzle of a vacuum transfer device, as well as a pair of contact tines biased towards the centerline axis to define a contact pinch point for an exposed core of a wire inserted into the connector. A contact surface is defined by a member of the cage structure for electrical mating contact with a respective contact element on a component on which the connector is mounted.

A plug arrangement having a plug and a cable that is connected thereto and includes at least one inner conductor and an outer conductor surrounding the inner conductor(s); an axial terminal section of the outer conductor is electrically connected to a sleeve portion of an outer conductor housing of the plug, said sleeve portion surrounding the outer conductor; a crimp point comprising a radial constriction of the sleeve portion is located between the axial terminal section of the outer conductor and the axial end of the inner conductor in the longitudinal direction (L) of the cable.

A coaxial cable connector comprising an inner sleeve, a nut and an outer sleeve, wherein the inner sleeve includes a first outer flange, a first rear extension portion, and a first surface being between the first outer flange and the first rear extension portion; the nut includes an inner threaded surface, and a first inner flange being between the first outer flange and the first surface; the outer sleeve includes a second rear extension portion and a second inner flange being on the first surface and an annular space formed between the first and second rear extension portions, wherein the outer sleeve further comprises a second outer flange disposed on the out surface of the outer sleeve outside the annular space, wherein the second outer flange has a maximum diameter greater than an outer diameter of the second inner flange, and an axial distance between a front end of the second outer flange and a rear end of the outer sleeve is greater than twice of that between the front end of the second outer flange and a front end of the annular space.

The invention relates to a contact assembly for plug connections, i.e., charging plugs, for transmitting electric power, having at least one device for producing an electrically conductive connection and at least one device for cooling purposes, i.e., for dissipating heat produced by the transmission of electric power using the conductive connection, wherein the electrically conductive device has at least one connection region for coupling to at least one cooling area border and at least one contact region, and the coupling is carried out directly in an integrative manner so that the cooling effect is supported as a result of the at least partly direct physical contact between the electrically conductive device and the coolant. The invention additionally relates to plug connections, i.e., charging plugs, comprising at least one such contact assembly.

A terminal of the present disclosure is the terminal to be connected to a wire including a core and includes a terminal body and a sliding portion. The terminal body includes a sandwiching portion. The sliding portion is slidable in a front-rear direction between a partial locking position and a full locking position. The sliding portion includes a pressurizing portion configured to press the sandwiching portion at the full locking position to sandwich the core in a first direction by the sandwiching portion, at least a pair of first contact portions configured to contact the core in the first direction when the core is inserted into the sliding portion, and at least a pair of second contact portions configured to contact the core in a second direction intersecting the first direction when the core is inserted into the sliding portion.

A connector is provided with three or more terminals to be respectively connected to wires, and a housing for holding the three or more terminals. The three or more terminals are arranged along a first direction. Each of the terminals includes a wire connecting portion to be connected to the wire, a terminal connecting portion to be connected to a mating terminal and an intermediate portion provided between the wire connecting portion and the terminal connecting portion. Three or more of the terminal connecting portions are arranged at intervals along the first direction. Three or more of the wire connecting portions are arranged at intervals along the first direction. The intervals and the intervals are different from each other. Three or more of the intermediate portions are formed to have mutually different shapes according to differences between the intervals and the intervals.

A crimp ferrule includes an assembly portion assembled on a non-circular internal cross section of a multi-core cable and a diameter compensation portion forming a circular external cross section of the crimp ferrule on the multi-core cable. The assembly portion and the diameter compensation portion are arranged successively in an axial direction of the crimp ferrule.
