Bayonet Neill-Concelman (BNC) connector are disclosed. The BNC connector comprises: an insulating housing; a signal receiver mounted in the housing for receiving a signal from a BNC plug; and a switch mounted in the housing and configured to connect to a first circuit, and when the BNC plug is connected to the BNC connector, the switch configured to connect to a second circuit for the second circuit.

A switch includes an insulating barrier that blocks an electrical conductivity path between a plug prong and a contact of an electrical receptacle. It further includes a switched alternative conductivity path between the plug prong and the contact of the electrical receptacle. A portion of the switch is inserted into the electrical receptacle. The switch receives the plug prong, and the switch is substantially flush with a wall that includes the electrical receptacle.

An electrical feedthrough assembly has a lower assembly having a first end and a second end. The lower assembly includes an outer body with a lower housing and an upper housing disposed within a bore of the outer body and a first conductor extending from the lower housing to the upper housing. Additionally, the lower housing extends axial outward from the outer body to form the first end and the upper housing extends axial outward from the outer body to form the second end. Further, the electrical feedthrough assembly has an upper assembly having body extending from a first end to a second end. The second body includes a pin end at the first end inserted into an opening of the second end of the lower assembly. A second conductor is disposed within the body. A piston is disposed within the body configured to move the second conductor.

An electrical connector includes: an insulative base; a fixed terminal secured to the insulative base; and a movable terminal including a securing portion fixed to the insulative base, a connecting portion, a contacting portion in touch with the fixed terminal, a first and a second beams at two opposite sides of the connecting portion, and a tail, wherein at least one of the first and second beams has a first portion substantially perpendicular to the connecting portion and a second portion substantially parallel to the connecting portion.

The present disclosure provides a safety socket, in which: the electrical connecting component includes a fixed terminal, a plughole component including three static contact pieces and a movable contact piece enclosing a plughole, an elastic component forcing the movable contact piece to deviate to the inner side of the plughole, and a connecting terminal for dynamically electrically connecting the plughole component and the fixed terminal; the bottom of the plughole component is provided with a liftable pressing rod, and when the pressing rod is pressed down, the connecting terminal and the fixed terminal can be forced to contact and conduct through a lever component.

An arc prevention system including a jack having a receptacle, with the receptacle having an upper wall, a bottom wall, two opposing side walls and a back wall between the two opposing side walls, a sensor unit positioned on the back wall of the receptacle, where the sensor unit is positioned on the back wall of the receptacle such that the sensor unit engages a plug inserted into the receptacle.
