Patent ID: 7959465

Claim:
An electrical contact device, comprising: a contact body; and a contact chamber adapted to accommodate said contact body that is insertable into the contact chamber through an assembly opening in a direction of insertion, and, in an operational position, the contact body being stopped within the contact chamber, at least one element of the contact chamber lying against a stopping surface of the contact body, which generally points in a direction opposite to the insertion direction, in such a way that a removal of the contact body is generally prevented counter to the direction of insertion, a center axis of the assembly opening having a lateral offset transversely to the direction of insertion with respect to a center axis of the stopped contact body; and an elastically flexible spring displaceably situated in the contact chamber in the direction of insertion, behind the assembly opening, the spring extending into a path of the contact body, narrowing the path for the contact body and adapted to be deflected by the contact body, the spring being adapted to be stressed in an assembly position during the insertion of the contact body and to move the contact body laterally, so that, after full insertion into the contact chamber, the contact body is pressed, by the spring in the contact chamber, with the stopping surface at least partially behind a stationary latching shoulder of the contact chamber, and is further adapted, when the contact body is mounted, to be pushed into a latching position which secures a position of a fully inserted contact piece.
