Abstract: An electrical contact has a contact surface adapted to contact a mating contact. The contact surface has a plurality of rotatable rolling contact bodies made of an electrically conductive material.

Abstract: An electric contact for an electrical plug connection includes a receptacle open against a plugging direction and adapted to receive a mating contact in the plugging direction and a plurality of roller contact bodies made of an electrically conductive material and projecting into the receptacle. The roller contact bodies are rotatably held on at least a pair of opposing sides of the receptacle and each form a part of a contact surface adapted to contact the mating contact.

Abstract: An electrical connecting unit for an electrical connector comprises an adhesive disposed at least partially circumferentially around the electrical connecting unit or at at least a side of the electrical connecting unit. The adhesive is elastically and/or plastically deformable and adheres to the electrical connecting unit to provide a seal for the electrical connector.

Abstract: Electrical contact (19) having a housing (2) in which an electrical conductor (1) is embedded, the housing (2) having a recess (3), the electrical conductor (1) being inserted into the recess (3), an intermediate space (20) between the conductor (1) and the housing (2) being filled with a sealing material (21), the conductor (1) extending in the longitudinal direction through the housing (2), the conductor (1) having a web (15, 16), the web (15, 16) extending transversely relative to the longitudinal direction around the conductor (1), the web (15, 16) protruding by a predetermined height beyond a lateral face (6, 7) of the conductor (1), the sealing material (21) being arranged at one side of the web (15, 16).

Abstract: A contact pin is disclosed with first and second end portions and a bending portion located therebetween, wherein the cross section of at least one end portion has a preferred bending direction (V1) and at least one bending resistance direction (R1) and wherein the moment of inertia of the cross section of the at least one end portion is smaller in the preferred bending direction than in the bending resistance direction. If such contact pins are bent perpendicular to their longitudinal extension (Z) by a bending force in one direction (F), then the direction of the actual bending (X) deviates from the direction of the bending force. In order to eliminate this deviation, the difference between the moments of inertia in the preferred bending direction and in the bending resistance direction in the cross section of the bending portion is smaller than in the at least one end portion.
