Abstract: An electrical connector consists of a connector housing (10) and at least one electrical contact element (1). The connector housing (10) and/or the electrical contact element (1) have a lead content of <0.1 weight percent. A method for manufacturing a contact element from a blank which has a lead content of <0.1 weight percent, uses the following method steps: Loading the blank into a manufacturing machine; producing a pin region or a socket region for electrically contacting another, opposite contact element; producing a fixing region for fixing the contact element in an insulating body; producing a crimp region for electrically connecting a conductor to the contact element or finishing the crimp region if the blank has already been previously prepared on a different machine; and removing the finished contact element from the manufacturing machine.

Abstract: The disclosure relates to a modular plug connector which has a plug comprising a plurality of plug modules and has a mating plug comprising a plurality of mating plug modules, in which each plug module forms a plug module pair with a mating plug module, wherein the plug and the mating plug can assume an interconnected state and wherein at least one of the plug module pairs has at least one locking device, which can assume a locking state in the interconnected state of the plug and the mating plug, in which locking state the locking device prevents the plug module and the mating plug module of said plug module pair from separating from each other.

Abstract: Provided is a plug for use as a disconnector for current transformers. Two types of short circuits are provided in the plug. A first short circuit is used for diverting overvoltages by short-circuiting the electrical contacts in the plug. A second short circuit is provided for short-circuiting electrical contacts in the plug when the plug is not contacted. The short circuits are designed in such a way that the first short circuit is used as a fuse when the second short circuit fails.

Abstract: A plug connector housing has a connection opening for connecting the plug connector housing to a counter plug. A protective layer at least partly covers the plug connector housing, a seal lip on the connection opening protects the interior of the plug connector housing when connecting a counter plug, and a stabilizing collar, which protrudes from a wall of the plug connector housing, stabilizes the seal lip. In order to allow the plug connector housing to be easily coated and provided with a seal while preventing the formation of air pockets in the cavities of the injection molding tool, the stabilizing collar has at least one recess.

Abstract: Provided is a method wherein data are downloaded via a network and/or via a suitable platform via the internet, and fed into a 3D printer, wherein the 3D printer subsequently prints out a component and/or a blank component of a connector. Using a method of this type, a customer can adapt connectors to a machine design and also add additional technical components, if necessary, for example, sensors and displays.

Abstract: A latching device for a first system of plug connectors, which are fastened to a first mounting rail, and a second system of plug connectors, which are fastened to a second mounting rail, includes a passive latching part and an active latching part. When the active latching part is latched to the passive latching part, the first mounting rail and the second mounting rail are connected to each other, and the plug connectors located on the first mounting rail and the second mounting rail are brought into contact with each other.

Abstract: A connecting component formed by a first housing, within which there are disposed electrical components which are connected to coupling elements acting outwards, is oversheathed with an insulating envelope. The first housing is surrounded by a second housing, the coupling elements are guided through corresponding openings of the second housing, and the space between the two housings is overcasted with a polyurethane plastic compound. After curing, the thus formed sheath of the housing has, with only one process step, a shape identically reproducing that of the second outer housing.
