Disclosed herein is a safety outlet. The safety outlet includes a casing having at least one hole into which a pin of a plug is inserted; and at least one drain pipe forming a drain channel for independently communicating the at least one hole and the outside of the casing; wherein the drain channel provided in the at least one drain pipe each serves as drain passage separated from each other, and the drain pipe is partitioned so as to maintain sealing between inside of the casing and the drain channel, wherein a contact portion connected to a power terminal arranged outside of the at least one drain pipe is provided in the at least one drain pipe.

A connector is provided with a first housing and a second housing connectable to each other, a detector arranged movably to a standby position and a detection position with respect to the first housing, a pair of second terminal fittings arranged in the second housing, and a shorting terminal arranged in the second housing to short-circuit the pair of second terminal fittings. The detector includes a releasing portion for releasing a short-circuit state of the pair of second terminal fittings by the shorting terminal as the detector reaches the detection position from the standby position.

An electrical connector for a safety restraint system of a motor vehicle comprises a housing, a pair of electrical terminals, a shunt and a connector position assurance (CPA) device. The housing includes a first end and a second end, the second end extending in a mating direction of the connector. Each of the electrical terminals traverses the housing from the first end to the second end. The shunt is adapted to short-circuit the pair of electrical terminals, and comprises two shunt arms each having a contact portion and a linking portion, and a shunt bridge linking the linking portions of the shunt arms. The CPA device is moveably arranged in the housing between an unlocked position and a locked position. In the locked position the CPA device lifts the shunt from a short-circuiting position across the terminals.

Disclosed are methods and devices for testing downhole connector electrical systems and cable integrity during installation of a permanent completion, including a customized retrievable plug arm assembly connectable to the completion during RIH, the tool mimicking a retrievable ESP, but without motor, and can be employed with or without pressure isolation. Another method employs a slidable starpoint located within the downhole wet mate connector of the completion to provide continuous electrical contact between the phases when no retrievable assembly is in place. When a retrievable assembly is later put in place, the slidable starpoint is moved into a second position that no longer provides electrical contact between the phases. Another method uses fusible links installed between two conductors within the downhole electrical connector system of the completion to provide similar electrical contact between phases, the fusible link configured to melt away once motor current is sent through the conductors.

The present disclosure discloses a safety plug comprising two pins, an insulating housing, a limiting member, and an operating member. The operating member is configured to drive the limiting member to be changed between a position-limited position and an unlocked position. First ends of the two pins extend into the insulating housing, a short-circuit protection circuit is disposed in the insulating housing, and the short-circuit protection circuit is disposed in a path in which the two pins move away from the insulating housing. When the limiting member is in the position-limited position, a limiting fit is defined, and the first ends of the two pins are spaced apart from the short-circuit protection circuit. When the limiting member is in the unlocked position, the limiting fit is released, and the insulating housing is pulled to enable the short-circuit protection circuit to short circuit the two pins.

A method includes plugging a plug into a socket, wherein the plugging includes pushing the plug into the socket at least up to a point that a latch clicks into the plug and locks the plug in place. Pressing down on a lever that rotates around an axis causes the lever to be pushed down. This results in the latch moving away from the plug and unlocking the plug from the socket, to thereby allow the plug to be separated from the socket.

When the limiting member is in the unlocked position, the limiting fit is released, and the insulating housing is pulled to enable the short-circuit protection circuit to short circuit the two pins.

A shorting terminal includes a base portion, a contact portion, a folded portion, an opposing portion and a protruding portion. The base portion is in the form of a flat plate. The contact portion can short a pair of terminal fittings by contacting the pair of terminal fittings. The folded portion extends in such a manner as to be folded from the base portion. The opposing portion extends from the folded portion toward the contact portion and is formed such that an interval between the base portion and the opposing portion is smaller than an interval between opposing inner surfaces of a shorting terminal holding chamber. The protruding portion extends from the opposing portion to the contact portion and is formed such that an interval between the base portion and the protruding portion is larger than the interval between the opposing inner surfaces of the shorting terminal holding chamber.

A connector arrangement includes a plug nose body; a printed circuit board positioned within a cavity of the plug nose body; and a plug cover that mounts to the plug nose body to enclose the printed circuit board within the cavity. The printed circuit board includes a storage device configured to store information pertaining to the electrical segment of communications media. The plug cover defines a plurality of slotted openings through which the second contacts are exposed. A connector assembly includes a jack module and a media reading interface configured to receive the plug. A patch panel includes multiple jack modules and multiple media reading interfaces.

A short-circuit probe for short-circuiting an inner conductor with an outer conductor in a multiway coaxial plug includes an electrically-conductive contact spring comprising a holding and stabilizing section and a contacting section. The contacting section is bent and comprises an inner-conductor contact section and an outer-conductor contact section. A housing comprises: a receiving space; an inner-conductor insertion opening in a first end face, via which the short-circuiting inner conductor of the multiway coaxial plug can be inserted into the receiving space and can be brought into contact with the inner-conductor contact section; and a laterally and/or radially aligned outer-conductor contacting opening, wherein the outer-conductor contact section of the contact spring passes through the outer-conductor contacting opening and can be brought into contact with the outer conductor. The contact spring is arranged inside the receiving space and extends over a predominant length of the housing.
