Adaptor for protecting mains plugs against unauthorised apparatus use

摘要

An adaptor for protecting mains plugs (20) against unauthorised apparatus use, which, for example, has the form of an intermediate plug or a plug strip, has a dedicated mains plug (2) and has at least one dedicated built-in plug socket (4). A clasp (14), which in general fits a large number of different mains plugs (20), can be locked in different positions over the built-in plug socket (4), by means of a locking device (12). Furthermore, the same locking device (12) allows a switch to be operated which controls the electrical connection between the plug (2) and the plug socket (4) of the adaptor. <IMAGE>
