Abstract: Disclosed is a closing cap for media-tight sealing of a plug face of a plug-and-socket connector, in particular a round plug-and-socket connector, wherein the closing cap can be detachably fixed to a plug-and-socket connector housing, wherein the closing cap is configured, such that a further closing cap of identical construction can be detachably fixed to the closing cap. The closing caps can be stored, for example stacked one on top of the other, on a plug-and-socket connector housing in a switchgear cabinet. This simplifies storage in that when a closing cap is removed from one connector it may be stored on a closing cap of an adjacent connector.

Abstract: Disclosed is an electrical contact element for contacting an electrical strand conductor, wherein the electrical contact element has a connecting side and a plugging side. A splicing element is provided in a connecting sleeve that forms the connecting side so as to electrically contact an electrical strand conductor in a more effective manner. The splicing element is provided for the purpose of separating out the individual strands of the conductor, contacting as large as possible a surface of the individual strands and penetrating the surface of the strands during a squeezing or crimping action. The arrangement provides a reliable, electrical contact of strand conductors in which a surface of the individual strands that is not suitable for being contacted and is poorly conductive is penetrated.

Abstract: A disadvantage of the prior art consists in the fact that the RFID transponders attached to plug-in connectors have a range that is insufficient for many applications. The present disclosure provides a design for a plug-in connector housing with an RFID transponder integrated therein, which allows a range that is greater than the one possible in the prior art. This object is achieved as a result of the fact that the antenna of the RFID transponder includes a slot, so that the antenna is a slot antenna.

The plug-in connector includes a seal which seals at the same time the contact support and a section of the cable that protrudes into the housing.

Abstract: A holding frame for a plug-type connector is intended to have good heat resistance and a high level of mechanical robustness and, when installed in a metallic plug-type connector housing, enable protective grounding while at the same time being convenient to use, in particular during the replacement of individual modules. To this end, it is proposed to manufacture the holding frame at least partially from spring-elastic sheet metal. For this purpose, the holding frame can have a basic portion and a deformation portion, which are formed from different materials. The basic portion is used for fixing an accommodated module in a plane. The deformation portion can assume an insertion state and a holding state, wherein the insertion state permits insertion of at least one module into the holding frame in a direction transverse to the plane and an accommodated module is fixed in the holding state.

Abstract: Provided a holding frame for a plug connector with a good heat resistance and a high mechanical robustness and to enable a protective earthing during installation in a metallic plug connector housing, yet at the same time guarantee a convenient serviceability, in particular during replacement of individual modules. To achieve this aim, the manufacture of the holding frame at least partially from resilient sheet metal is proposed. Due to the resilient properties of the sheet metal, it is possible to insert or remove modules with very little effort. The sheet metal can be bent and/or folded in certain regions and can thereby be strengthened in targeted regions, in order to achieve a particularly advantageous combination of holding and actuating forces.

Abstract: Provided is a plug connector for connecting electrical lines. The plug connector comprises a first plug connector housing and a second plug connector housing which can be plug-connected and locked to one another. The plug connector housings have two types of locking devices for locking purposes. In this case, the first type of locking device forms, from a rotary pin and a rotary bearing, a rotation axis about which the plug connector housings are mounted such that they can rotate in relation to one another. The second type of locking device is a type which is known from the prior art and which serves to fix the first plug connector housing to the second plug connector housing.

Abstract: A power network having special junction boxes and an associated method for operation and evaluation which makes it possible, after construction and wiring, to recognise and to simulate the topology of the power distribution automatically is provided. On this basis the current consumption can then be determined in certain branches, for example also in a tree or ring network structure. In particular, deviations from the desired value, for example a disproportionately high current consumption, can be recognised and localised, so that as a consequence certain load and/or entire power network segments can be switched on and off. For analysis, the corresponding values of relevant electrical variables can be continuously observed, stored in a database, held for any period of time and displayed graphically. Connection errors, wire breakage and overload and undervoltage can be recognised and eliminated by analysing the values of the respective electrical variables.
