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.

A diagnosis plug-in connection comprising an electrical plug connector and a mating electrical plug connector. The electrical plug connector comprises a diagnosis module with an oaten conductor contact and an inner conductor contact within the outer conductor contact. The mating plug connector comprises a diagnosis head with an electrically conductive spring cage, which is designed for electrical and mechanical connection to the outer conductor contact of the diagnosis module of the plug connector. The spring cage electrically and mechanically contacts the inner conductor contact of the diagnosis module of the plug connector when the plug connector is plugged together with the mating, plug connector.

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.

Proposed is a connector apparatus with a switch for improving contact reliability, the connector apparatus being capable of enabling an operator to electrically test proper coupling of a connector position assurance member. When the connector position assurance member is completely coupled to a first housing, a pair of switches are stably brought into contact with each other in a state of being inserted into a switch guide recess formed in a second leg portion. Therefore, the pair of switches can be safely protected from foreign substances, etc., thereby improving the contact reliability of the first and second switches.

A connector includes: a terminal fitting; an electric wire connected to the terminal fitting; a first housing in which the terminal fitting is stored, the first housing constituting a fitting part with a counterpart connector; a seal member disposed so as to surround an outer periphery of the first housing; a front holder mounted on the first housing so as to prevent the seal member from coming out from the first housing; and a second housing including a short terminal, the short terminal being configured to allow a fitting state with the counterpart connector to be detected. The second housing is attached to the first housing and retained by the front holder in a state in which the second housing is displaceable in a direction intersecting a fitting direction with the counterpart connector in a posture in which the short terminal faces the counterpart connector.

A plug connector includes a first connector half configured as a socket connector and a second connector half configured as a plug connector, each of the connector halves including an insulating body housing at least a respective pair of electric contact elements, respectively female and male, a short-circuit element being provided between the contacts of the socket connector half, adapted to hold such contacts shorted upon unmated connector, wherein the short-circuit element is made from a strip of resilient metallic material, shaped so as to constitute a spring and to offer, at each of its ends, a resilient contact, the first end of the short-circuit element being substantially rigid and stable in contact with a respective female electric contact element, while the second end of the short-circuit element, upon plug connector unmated, goes intimately into contact with the other element of female electrical contact of the socket connector.

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.
