摘要:
An embodiment of the invention relates to a device for protecting a load, with a first current path having two lines, and a monitoring arrangement for detecting an imminent overload of the electrical load. In order to enable the detection of an imminent overload on a load, it is proposed that the monitoring arrangement includes a first temperature measuring unit, an evaluation unit and a first transducer, which establishes an electrically conductive connection between the two lines of the first current path, wherein the first temperature measuring unit is electrically isolated from the first transducer and can record a temperature of the first transducer, wherein the evaluation unit can determine, using recorded temperatures of the first transducer, a temporary heating behaviour of the first transducer, and can determine, by evaluating the determined temporary heating behaviour of the first transducer, an imminent overload on the load.

A signaling appliance is provided, in particular a signaling column for indication of at least one operating state of a technical appliance such as a machine, an installation, a vehicle or the like, having at least one holding apparatus (5) for holding an electrical light-emitting element, in particular an incandescent lamp, which can be produced at a lower cost and/or provides further application options, in which case the electronics mount can be installed very easily, for example for commercially available signaling elements and/or bulbs. According to the invention, this is achieved in particular in that the holding apparatus (5) which is provided for holding the electronics mount (9) is also designed to hold the signaling element (7), with the holding apparatus (5) having at least one guide apparatus (8) for lateral guidance of the electronics mount (9) to be installed.

摘要:
At least one embodiment of the invention relates to a contact apparatus for SMT placement on a printed circuit board, the contact apparatus being provided for the electrically conductive connection to at least one conductor track on the printed circuit board. The contact apparatus includes a contact holder for accommodating the contact, and the contact of the contact apparatus is provided for the connection to at least one electrical mating contact. The contact apparatus is designed on an SMT basis and can therefore be produced inexpensively and fitted easily. According to at least one embodiment of the invention, the contact apparatus has a first housing part, the housing part having at least one elongate cutout for accommodating the contact holder, and at least one stop for the contact being integrally formed on the housing part, which stop is provided for the purpose of absorbing insertion forces when contact is made between the contact and an electrical mating contact.
