Abstract: An electrical connection device is arranged for connection to a machine cable and includes a pin and a socket. The pin and the socket have engagement surfaces with the pin or socket having another surface that forms a wedging surface for the device. The pin and the socket are moveable relative to each other from a released position to an engaging position in which the engaging surfaces form an electrical contact. The device also includes a wedge portion arranged to impart a force on the wedging surface by contacting the wedging surface on movement to the engaging position. The pin and the socket are arranged so that the engagement surfaces move into opposing relationship on movement to the engaging position and the force imparted on the wedging surface biases one engagement surface against an opposing engagement surface.

Abstract: The present invention provides an electrical connector for connecting a core of a machine cable (37) to a pin (28) or a socket (32) of an electrical connection device. The connector has a first part and a second part. The first and second parts have first and second locking surfaces respectively and first and second separate contact surfaces (50, 52). The second part further includes a projection for securing the core of the machine cable and which is electrically connected to the second contact surface. The contact surfaces are so arranged that when the locking surfaces are interlocked, the contact surfaces are in electrical contact with each other so that an electrical contact is established between the core of the machine cable and the pin or socket.

Abstract: The present invention provides an electrical connection device for a machine cable comprising a first connector having a first contact and a second connector having a second contact the connectors being moveable between a disengaged condition in which the first and second contacts are remote from each other and an engaged condition in which the first and the second contacts are electrically connected. The device also comprises a drive for imparting a driving force to drive the first and the second connectors relative to each other whereby the first connector and the second connector move between the disengaged and the engaged positions. The drive is arranged to distribute the driving force around at least a portion of at least one of the first and the second connectors to minimize wedging, canting or seizing between connector surfaces and allows minimal mechanical clearance to provide a narrow path.
