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.
Claims20
An electrical contact, comprising:
- a contact surface adapted to contact a mating contact, the contact surface having a plurality of rotatable rolling contact bodies made of an electrically conductive material;
- and
- a rolling body cage having a plurality of openings in which the rotatable rolling contact bodies are disposed, widths of each of the plurality of openings defined on a first side and a second side of the opening are less than a width of the widest portion of the rotatable rolling contact body, the widest portion of the rotatable rolling contact body arranged in a middle of the opening between the first side and the second side of the opening such that the widest portion of the rotatable rolling contact body is positively held between the first side and the second side of the opening and within the rolling body cage only by the opening.
A plug electrical connection, comprising:
- an electrical contact including a contact surface having a plurality of rotatable rolling contact bodies made of an electrically conductive material, a rolling body cage having a plurality of openings in which the rotatable rolling contact bodies are disposed, and an unoccupied weakened area disposed between individual rotatable rolling contact bodies and/or disposed between a plurality of groups of rotatable rolling contact bodies, the weakened area is a recess extending through the rolling body cage in a direction transverse to a plug-in direction, the recess comprising an unoccupied opening having profile distinct from the plurality of openings, each of the rotatable rolling contact bodies is captured within the rolling body cage by one of the plurality of openings, the rolling body cage has a gap extending through the rolling body cage in the plug-in direction and separating the rolling body cage in a circumferential direction about the plug-in direction;
- and
- a mating contact matable with the electrical contact in the plug-in direction, the contact surface of the plurality of rotatable rolling contact bodies forming an electrical connection between the electrical contact and the mating contact.
An electrical contact, comprising:
- a contact surface adapted to contact a mating contact, the contact surface having a plurality of rotatable rolling contact bodies made of an electrically conductive material;
- and
- a rolling body cage having a plurality of openings in which the rotatable rolling contact bodies are disposed, each of the rotatable rolling contact bodies is positively held within the rolling body cage by one of the plurality of openings, with each of the plurality of openings of the rolling body cage sized to limit motion of each of the rotatable contact bodies in a direction radially outward from the rolling body cage and transverse to a direction of insertion,
- wherein widths of each of the plurality of openings defined on a first side and a second side of the opening are less than a width of the widest portion of the rotatable roller contact body, the widest portion of the rotatable rolling contact body arranged in a middle of the opening between the first side and the second side of the opening such that the widest portion of the rotatable rolling contact body is held between the first side and the second side of the opening and within the rolling body cage.
