A clamp for a male terminal of a power source, consisting of a frustoconical body projecting out of a base surface that is part of the source against which it rests with its greatest diameter. The clamp comprises at least one first ring-shaped portion with an open section of its circumference. Said first ring-shaped portion has such a diameter that a predetermined radial clearance exists when it axially fits upon said frustoconical body, and also has two jaws which axially project out of its circumference and are located at the ends of the open section of the circumference. The jaws are in opposed, spaced-apart relationship and a device is adapted to cause them to move toward each other to clamp the ring-shaped portion around the frustoconical body, by eliminating the radial clearance. The clamp comprises at least one first plate-like element associated with said ring-shaped portion of the clamp on the side on which it is inserted onto the frustoconical body of the male terminal, which is made of an electrically non-conductive material and has a through hole whose diameter is adapted to create a radial interference with the diameter of the frustoconical body of the male terminal proximate to said base surface from which it protrudes.

Various implementations of grounding cross connectors are disclosed. The grounding cross connectors may be used to clamp together two or more, often perpendicular, conductors. In some implementations, a grounding cross connector includes an upper clamping pad and a lower clamping pad held together by a pair of threaded fasteners. A pair of perpendicular conductors may be placed in between the clamping pads and secured together by torquing nuts on the threaded fasteners. The upper clamping pad may include a hook through which one of the threaded fasteners may pass, thereby allowing the upper clamping to rotate relative to the lower clamping pad.

A clamp provides electrical communication between a first conductor and a second conductor. The clamp includes a first housing portion having a first surface, a second surface, a first housing bore, and a cavity, the first housing bore extending along a longitudinal axis. The clamp further includes a clamp member at least partially disposed within the cavity of the first housing portion, the clamp member including a first clamp surface adjacent the second surface of the housing in a facing relationship. The clamp further includes a shaft oriented parallel to the longitudinal axis, the shaft coupling the first housing portion and the clamp member. The clamp further includes a second housing portion movably coupled to the first housing portion by the shaft, the second housing portion including a second housing bore and a second clamp surface, the second housing bore aligned with the longitudinal axis, the second clamp surface adjacent the first surface of the first housing portion in a facing relationship.

A connection terminal for connecting an electrical conductor includes: an insulating housing having at least one conductor terminal device which in each case can be operated by an actuation element mounted in the insulating housing so as to be pivotable about a pin. The at least one conductor terminal device includes a clamping point for the electrical conductor that is formed by a contact element arranged in a stationary manner in the insulating housing and a clamping spring that is arranged in the insulating housing so as to be movable, by the actuation element, between an open position and a clamping position by a free leg of the clamping spring being articulated to the actuation element by a connecting element such that the clamping spring can be moved into the open position by a pivot movement of the actuation element in a first direction.
