An electric motor, in particular a radiator fan motor of a motor vehicle, has a stator which is fitted with a rotating-field winding, and a rotor which is mounted such that it can rotate in relation to the stator. A converter electronics system is provided, wherein a number of contact elements for insulation-free or enamel-insulated connection contacts of at least one component of the converter electronics system and/or for enamel-insulated winding ends of the rotating-field winding are mounted on a printed circuit board. The contact elements are in the form of clamping contacts or insulation-displacement terminal contacts.

An electrical connector for electrically connecting a coaxial cable, which includes a pin and a shield separated by a dielectric element and protected by an insulated layer, to an antenna disposed on a thin support. The electrical connector includes a shield part having a leg and a bridge to clamp the shield between the bridge of the shield part and the antenna and to electrically connect the shield to the antenna. Each of the legs of the shield part includes a penetration means designed to penetrate through the thin support. The penetration means and the leg of the shield part are not coplanar. An antenna system including such electrical connector and a vehicle comprising such antenna system and associated method.

A connector includes a first insulator having a recessed portion formed in a first retaining surface and a projection formed in the recessed portion to project higher than the first retaining surface, and a second insulator having a protrusion portion formed on a second retaining surface and a projection accommodating portion of recess shape formed in the protrusion portion and is deeper than the second retaining surface, the first insulator and the second insulator being joined to each other such that the projection is inserted in an opening portion of a sheet type conductive member, that the sheet type conductive member and an electric wire are held between the first retaining surface and the second retaining surface, and that the sheet type conductive member and the electric wire are disposed to overlap each other between the recessed portion and the protrusion portion.

A contact is accommodated in a contact accommodating portion of a second insulator, an end portion of an electric wire is accommodated in an opened electric-wire-end-portion accommodating portion of a projection of a first insulator, the projection is accommodated in a projection accommodating portion of a contact with a flexible conductor being sandwiched therebetween and such that the opened electric-wire-end-portion accommodating portion is opposed to an electric-wire connection piece of the contact, the electric wire extends from the electric-wire-end-portion accommodating portion and makes contact with an electric-wire contact portion of the electric-wire connection piece of the contact, and a part of the flexible conductor is sandwiched between an outer surface of the projection and a conductor contact piece of the contact and makes contact with the conductor contact piece of the contact, whereby the electric wire is electrically connected to the flexible conductor via the contact.

A connection portion between a single-core line electrical line and a stranded electrical line is prevented from bulging in the diameter direction. A conductor exposed portion is formed on an end portion of the single-core line electrical line, and an individual wire exposed portion is formed on an end portion of the stranded electrical line. A collapsed portion is formed on the conductor exposed portion, and a connection block portion is formed by welding together individual wires of the individual wire exposed portion. The compressed portion and the connection block portion are joined in an overlapping state. At this time, the collapsed portion is bent such that a level difference is formed in the diameter direction such that the single-core line electrical line and the stranded electrical line are joined approximately coaxially.
