Locking device for a plug-in connection

Abstract: The invention relates to a locking device for a plug-in connection between a plug and a socket. In accordance with the invention an actuator ( 4 ) and a blocking slide ( 6 ) are provided, wherein the actuator ( 4 ) is rotatable about an axis of rotation, the blocking slide ( 6 ) is displaceable in the longitudinal direction thereof between an unlocking position and a locking position, and the actuator ( 4 ) and the blocking slide ( 6 ) are formed in such a way and interact with each other such that a rotation of the actuator ( 4 ) is always combined with a longitudinal displacement of the blocking slide ( 6 ) and vice versa, wherein a longitudinal displacement of the blocking slide ( 6 ) by means of a rotation of the actuator ( 4 ) is always possible, whereas a rotation of the actuator ( 4 ) by means of a longitudinal displacement of the blocking slide ( 6 ) is possible only outside the locking position. A locking device of this type for a plug-in connection between a plug and a socket is thus provided, which enables simple and economical axial locking, which cannot be manipulated.

Safety relay and safety-related communication system

Abstract: A safety-related communication system includes a safety relay with signal inputs of an input signal current circuit that connect the safety relay to a control device for monitoring the input signal circuit. The safety relay also includes at least two load outputs of a load current circuit for connecting to a load. Switching elements are connected in parallel and configured to switch the load current circuit on or off based on an activation signal at the input signal current circuit. A diagnostic device monitors faults in the load current circuit and/or the safety relay. A signaling device connected to the signal inputs provides an impedance for the input signal circuit. The impedance is tuned to the control device during a fault-free state and is detunable upon detection of a fault so as to signal the detected fault to the control device via the input signal current circuit.

Modular data system with inductive energy transfer

Abstract: The invention relates to a device for electrical energy supply and/or data supply of end devices via inductive (coupling,) comprising an oblong holding apparatus (1) and a plurality of transmitting coils (20) arranged next to each other which generate magnetic field lines along the holding apparatus (1). According to the invention, structurally narrow end devices (31) have flat receiving coils (30), the plane of which is aligned perpendicular to the longitudinal extension of the holding apparatus (1).

Method and apparatus for transmitting data over a bus-network using broadcast

Abstract: The method involves transferring data via a bus network to which several subscribers are connected, whereby data are transmitted every communications cycle using a point-to-point transmission protocol from at least one subscriber (master) to at least one further subscriber (TN1,..; STN1,..) and defining a broadcast message within the protocol within which selected data can be transmitted in a broadcast transmission mode. Independent claims are also included for the following: (a) a device for use in a bus network, especially for implementing the inventive method (b) and a bus network adapted for implementing the inventive method.

Excess voltage protection device

Abstract: The device (1) has deflectors (7) e.g. suppressor-diodes, connected with a conduction path (6) at one terminal (9) and with a common connection point (11) at another terminal (10), so that the deflectors lie on a common reference potential. The point (11) does not exhibit connection to an earth and is connected with a connecting element (12). The connecting element is accessible from outside of a housing, so that the connecting element is connectable with a connecting element of another over-voltage protection device.
