The invention relates to a contact element, made of an electrically conductive contact material. In order to provide a contact element which can be passed repeatedly and non-destructively through a housing or a seal of a plug connector in and/or opposite to a direction of insertion (E), a contact element is provided comprising a body extending in the direction of insertion (E) and a position securing element disposed on an upper side of the body, projecting upwards out of an opening in the body transversely to the direction of insertion (E), and that can be deflected elastically, the position securing element having a slope surface that is inclined against the direction of insertion (E), adjoining which, without any kinks or edges, are a curved section and an end section, and the end section ending with a free end within the cubature of the body.

A plug connector is provided in a plug housing and has a conductive braided wire that connects ends of a plurality of plug terminals opposite to contact points with receptacle terminals such that each plug terminal can move relatively to each other. A service plug has a plug connector and a receptacle connector.

Disclosed is a plug connector for positioning on a mating connector and for producing an electrically conductive connection. The plug connector comprises a guide means and a contact pin. The guide means is configured and positioned such that to produce the electrically conductive connection, contact bars of a contact socket of the mating connector can be guided by means of the guide means toward the contact pin, said contact bars encompassing the contact pin in a frictional engagement to establish electrical contact.

A secondary disconnect assembly is for an electrical switching apparatus. The secondary disconnect assembly includes a mounting member and a cradle assembly coupled to the mounting member and being movable among a plurality of positions with respect to the mounting member. The cradle assembly includes an inner cradle. When the inner cradle is disposed in a first predetermined one of the positions, movement of the inner cradle is restricted with respect to the mounting member. When the inner cradle is moved toward a second predetermined one of the positions, the inner cradle moves independently with respect to the mounting member.

A contact element for inserting a mating contact element along an insertion direction. The contact element includes an insertion opening for inserting the mating contact element and at least one contact lamella for electrically contacting the mating contact element, and a clamping sleeve that is displaceable along the insertion direction, relative to the at least one contact lamella, between a first position and a second position. The clamping sleeve and the contact lamella are in an operational relationship with one another such that when the clamping sleeve moves from the first position into the second position, the contact lamella is moved in a radial direction perpendicular to the insertion direction. The clamping sleeve includes a run-up element, which in a projection along the insertion direction through the insertion opening at least partially covers the insertion opening.

[Object] To provide a common plug for AC/DC which can easily prevent erroneous insertion into a plug receptacle.

[Solution] Provided is a common plug for AC/DC including at least one pair of connection terminals. At least one connection terminal of the at least one pair of connection terminals is able to rotate around an axis of an insertion direction into a socket so as to have a first state in a case where the connection terminal is inserted into a socket for supplying AC power and a second state in a case where the connection terminal is inserted into a socket for supplying DC power, the second state being different from the first state.

One embodiment is directed to a method of reading RFID tags in an interconnection system comprising at least one port. The method comprises initiating a localized read transaction to read any RFID tag attached to a first connector and any RFID tag attached to a second connector inserted into the port. The method further comprises, as a part of the localized read transaction, reading any RFID tag configured to respond to a first type of RFID interrogation signal, wherein the first connector comprises an attached RFID tag that is configured to respond to the first type of RFID interrogation signal; and, as a part of the localized read transaction, reading any RFID tag configured to respond to a second type of RFID interrogation signal, wherein the second connector comprises an attached RFID tag that is configured to respond to the second type of RFID interrogation signal. Other embodiments are disclosed.
