A piercing electrical connector includes a wire end connector. The wire end connector has a wire end body, a wire end terminal, and a wire cover engaged with the wire end body. The wire cover has a wire holding hole, and the wire end terminal has a piercing portion. The wire cover further has a clasping plate, a clasping arm and a first clasping head. The wire end body has a clasping groove, a clasping hole, a protrusion located in the clasping groove, a pre-locking groove and a locking groove that communicate with the clasping hole. When the wire end connector needs to be transported, the first clasping head extends into the pre-locking groove, and the protrusion abuts against a free end of the clasping plate so that the wire cover and the wire end body are pre-assembled together, and the piercing portion does not pierce a cable wire.

A field termination plug includes a contact retainer, a plug housing, a terminal connection unit, and a cover pivotally connectable to the plug housing. The plug housing includes a front portion and an accommodation portion. The terminal connection unit has contacts and piercing terminals electrically coupled to the respective contacts. When the plug housing carries the terminal connection unit and the contact retainer is attached to the front portion, the contacts are disposed on the front portion for electrical coupling to a network jack and the piercing terminals are disposed upward on the accommodation portion. When the cover is pivoted to an open position, the piercing terminals are exposed for disposition of a wire organizer for attachment of the wires. The cover pivoted to a closed position presses the wire organizer such that the wires attached to the wire organizer are terminated to the respective piercing terminals.

A conductive terminal comprises a body and a pair of first elastic cantilevers adapted to clamp a first conductor. The pair of first elastic cantilevers are connected to the body and accommodated within a first accommodation chamber formed in the body. Each first elastic cantilever or the body has a first elastic support structure. A free end of each first elastic cantilever is elastically supported on an inner wall of the first accommodation chamber by the first elastic support structure when the first conductor is clamped between the pair of first elastic cantilevers.

Disclosed herein are connection systems for establishing electrical connections across a sterile field. An example connection system includes a sensor connector, a probe connector, and a tether having a first end connected to the sensor connector and a second end connected to the probe connector. The sensor connector includes a piercing element. The piercing element is configured to pierce a sterile side of a drape and establish a first electrical connection with a receptacle of a sensor when the piercing element is inserted into the receptacle. The probe connector includes a probe-connecting means configured for a user to establish a second electrical connection between an electrical contact of the probe connector and a wire probe. The tether is configured to convey electrical signals between the sensor connector and the probe connector. Also disclosed herein are methods of connection systems for establishing electrical connections across a sterile field.

A power distribution system includes a plurality of wires extending between a first end and a second end. The power distribution system further includes a first power outlet selectively positionable at any position along a length of the wires. The first power outlet includes a first connection member connected to a first wire of the plurality of wires and a second connection member connected to a second wire of the plurality of wires. Moreover, the power distribution system includes a second power outlet selectively positionable at any position along the length of the wires. The second power outlet includes a third connection member connected to the first wire of the plurality of wires and a fourth connection member connected to a third wire of the plurality of wires such that each power outlet is connected to a different group of wires of the plurality of wires.

An electrical contact terminal includes a base portion for positioning and retaining the electrical contact terminal within a connector housing, an insulation displacement connecting portion extending upwardly from the base portion and comprising a pair of spaced apart arms defining an opening therebetween for receiving and making electrical contact with an electrical conductor, and a contact portion extending downwardly from the base portion and configured to float when the electrical contact terminal is retained and positioned within a connector housing. The contact portion includes a first arm, a second arm, and an arcuate base portion. The first arm extends downwardly and includes a first end attached to the base portion and an opposite second end. The second arm extends downwardly and includes a free first end closer to the base portion and an opposite second end farther from the base portion. The second arm is configured to deflect when making electrical contact with a mating contact pin. The arcuate base portion connects the second ends of the first and second arms.

Provided is a terminal for an electric wire connector including: a central erection piece configured to have cutting portions inclined downward and outward on both sides of its upper portion; a pair of outer erection pieces configured to be spaced apart at a desired interval on both sides of the central erection piece and have cutting portions that are inclined downward on the upper portion; a connector configured to connect the central erection piece and lower portions of the pair of outer erection pieces; an electrical wire entry portion configured to be a space through which the cutting portions face each other and be a path under which the electrical wire enters; and a core wire connector configured to be arranged on the lower portion communicating with the electric wire entry portion and be a space to connect the central erection piece and the outer erection piece.

A wire connection device includes an electrical wire, an insulation displacement terminal and a stress relaxation member. The electrical wire includes a conductor and an insulation coating on an outer periphery of the conductor. The insulation displacement terminal has a slot in which the electrical wire is fitted. The insulation displacement terminal is connected to the electrical wire by both side portions of the slot being in direct contact with the conductor and pressing the conductor elastically and plastically. The stress relaxation member is fitted in the slot of the insulation displacement terminal to suppress deterioration of a stress applied to the electrical wire.
