A bar connector comprises an elongate bar with a series of electrical attachment structures along a length of the elongate bar. Each wire electrical attachment structure is to secure at least one wire to the elongate bar. A flexible connector wire with two ends that connect to the elongate bar is used to establish an electrical connection between the at least one wire and a secondary distribution line by a crimp connector. A method of connecting an electrical wire with the bar connector is also claimed.

A shotgun stick for use with grounding devices is provided. An example shotgun stick includes a housing and a drive shaft supported within the housing. The shotgun stick further includes a clamp stick head attached to the housing at a first end and operably connected to a first end of the drive shaft such that rotation of the drive shaft actuates the clamp stick head. The shotgun stick also includes a ratchet locking module that selectively limits rotation of the drive shaft via engagement between a side pin and a ratchet gear of the ratchet locking module. The clamp stick head includes an exterior housing, a head sleeve that defines an opening configured to receive a tool attachment secured thereto, and a slotted inner sleeve positioned between the exterior housing and the head sleeve that prevents rotation of a tool attachment received by the head sleeve.

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.

An arrangement of stack spark gaps, whereby a stack spark gap has multiple electrodes and insulating elements that are arranged between the electrodes, with a first electrically conductive clamping element and a second electrically conductive clamping element, whereby the two clamping elements are arranged opposite to the front ends of the stack spark gaps, with at least one connecting element, by which the two clamping elements are connected to one another, and with connection elements for electrical connection to the stack spark gaps. A device is provided for holding the stack spark gaps together and having them make contact. Three stack spark gaps are arranged beside one another between the two clamping elements, at least one of which is electrically conductive, and the two clamping elements are connected to one another electrically via the connecting element and are arranged with the spark gaps so as to form a star circuit.

A terminal block for an oven, including a base, a terminal, a screw and a grounding copper sheet. A plurality of terminal mounting slots are provided evenly in the base along transverse direction. The middle or both sides of the terminal mounting slot are provided with retaining grooves penetrating the bottom of the base. An elastic buckle is provided at the upper portion of the retaining groove. The middle of the terminal is provided with a wire installation through hole which penetrates the both ends of the terminal mounted in the terminal mounting slot. The elastic buckle is pressed on the top of the terminal, the grounding copper sheet covers and fits the upper surface of the terminal and is fixedly connected by a number of screws. The screws pass through the top of the terminal and screw vertically into the wire installation through hole.

A circular plug-in connector for establishing a shielded plug-in connection to a mating plug-in connector includes: a contact carrier having at least one electrical contact element; a shielding sleeve that surrounds the contact carrier at least in part; and a screw housing that is rotatably connected to the shielding sleeve and adapted to screw the circular plug-in connector to the mating plug-in connector. A connection portion of the shielding sleeve is received in a receiving space of the screw housing The circular plug-in connector provides shielded contact between the screw housing and the shielding sleeve. The shielding sleeve includes a collar in the connection portion. The circular plug-in connector further includes a stopper for closing a receiving opening of the receiving space at least in part, such that the collar is trapped in the receiving space.
