Abstract: Disclosed is a holding frame for accommodating a circuit board, wherein the holding frame has a substantially rectangular basic shape and has two holding arms sticking out perpendicularly from the frame plane, each holding arm having a groove in which the circuit board can be held. A circuit board can thus be integrated in a heavy-duty plug connector in a mechanically stable yet low-wear manner.

Abstract: The problem addressed by the disclosure is that of specifying an inexpensive, easily operable and largely automatable and reusable apparatus and a corresponding method for monitoring the manipulation of a transportable object. For example, the disclosure can be used to monitor the actuation of an opening flap of a transportation box without a current. For this purpose, the apparatus has the following: a magnetic data memory for storing an item of control information; a permanent magnet for destroying this control information; a mechanism for destroying the control information in the magnetic data memory by means of the permanent magnet; a data interface; a data connection between the magnetic data memory and the data interface for interchanging data between the magnetic memory and the data interface in a bidirectional manner.

Abstract: Provided is a plug connection which ensures signal integrity, in particular at high data rates and with a large number of plug-in cycles, in a cost-effective manner. A dielectric is in each case arranged between the pin contacts of a connector and the socket contacts of a mating connector to ensure galvanic isolation and capacitive connection between them. In this way the connected circuit electronics can be simplified. There is no need for a coupling capacitor and impedance matching can be performed the geometric arrangement of the contacts. In particular, it ensures that there is a variety of different plug connections to choose from with different properties, in particular with different impedances and capacitances.

Abstract: In order to improve the signal integrity, for a connection device for twinax cables the connecting pad belonging to the respective drain wire is disposed directly between the two connecting pads of the two leads belonging to the same data line. Groups of connecting pads can be disposed so that they are offset with respect to one another in order to prevent crosstalk. To this end the data lines can be fastened to the connection device, which for example consists of a circuit board.

Abstract: For the transmission of high-frequency signals >2.5 GHz or 5 Gbps by means of a separable plug connection, the invention proposes a symmetrically shaped electric contact (1, 1?) that features a contact body (4) with the contact side (3) with U-shaped spring legs (13), as well as a connection end (5). Contact domes (15) that are directed toward one another and feature contact zones (16) that are narrower than the material thickness of the spring legs (13) are integrally formed onto both spring legs (13). When joining the two electric contacts (1, 1?) that are mated while they are turned relative to one another by 90 degrees in the mating direction, the contact domes (15) or their contact zones (16) of one electric contact (1, 1?) engage into the contact body (4) of the other electric contact (1, 1?) in a paired fashion such that electric signals travel distances with identical transit times on one leg and on the other leg and so-called stub effects, i.e.
