A receptacle and/or a plug of an electrical connector includes a proximal body portion defining transverse alignment slots extending through a side of the proximal body portion for contacts. A plug of an electrical connector includes a safety disk. The safety disk includes a hollow stem having at least one prong slidably inserted through a groove and captured within a central axial passage of a housing.

The present invention includes a plug bolt and a bolt seat. The plug bolt includes a bolt pin having a receiving hole that receives a circuit device including an RFID chip electrically connected with a main circuit and a radiation unit. The receiving hole defines a hole body arranged in an axial direction, and an open hole bottom at a bottom of the hole body. The main circuit includes a lower contact point. The radiation unit induces an effect of coupling feed with respect to the hold body to make the bolt pin forming an upper monopole antenna. The bolt seat includes a lower monopole antenna and a locking hole into which the bolt pin is insertable. When the lower monopole antenna is electrically connected with the lower contact point, the upper and lower monopole antennas jointly form a standard dipole antenna to emit a signal that is monitorable.

A plug connector part for connecting to a mating plug connector part includes: a housing part on which a plug-in section for a plug-in connection to the mating plug-in connector part is arranged; at least one contact element arranged on the plug-in section so as to make electrical contact with an associated mating contact element of the mating connector part; an electrical line arranged on the housing part and electrically connected to the at least one contact element; a strain relief element movably arranged on the housing part; and an adjusting element that can be brought into operative connection with the strain relief element. Via actuation of the adjusting element, the strain relief element is movable into a position in which the strain relief element fixes the electrical line, relative to the housing part, in a tension-loadable manner.

A cable guide apparatus has an oscillating link rotatable about an axis and a cable guide for the line cable. The line cable is fed from and into a reservoir based on the distance between the reservoir and the feed device and is guided by the cable guide. A simplified automatic connection of a line cable to a feed device is achieved and provides protective guidance and storage of the line cable by a cable guide apparatus in which the oscillating link can be moved linearly relative to the oscillation axis. A power supply system includes this cable guide apparatus. The related method comprises: a) retracting a connecting element, which is arranged on the line cable, into the cable guide apparatus and before, at the same time or afterwards b) moving the oscillating link from an extended to a retracted position relative to the oscillation axis in a linear manner.

A line cable comprises one or more conductors for transmitting electrical power and/or data and an elongate supporting element. A related power supply system for supplying electrical power and/or data to a movable electrical load via cables comprises at least one feed device and a connecting element, which can be connected to the feed device, of a line cable of the load. The line cable can be output or retrieved from a reservoir, which is carried along by the load, in accordance with a distance between the reservoir and the feed device. A connecting element for connection to a connection of a feed device for electrical power and/or data is arranged at one end of the line cable. The supporting element can be connected to the connecting element in a force-fitting and/or interlocking manner for the purpose of transmitting longitudinal tensile forces.
