Abstract (en)
[origin: EP0111756A2] 1. Multiple socket with a flush-mounted wall installation box (10), a support ring (9) which is fixed in the latter, a cover plate (1b), which exhibits an earth-contact plug cup (2b) provided for the connection of a first three-pin plug with earth contact and at least one non-earth-contact plug cup (3b) provided for the connection of at least one second two-pin all-insulated plug, and an earth-contact double plug socket (4b) which is recessed in the flush-mounted wall installation box (10) and which carries two first pin base socket contacts associated with a first pole and two second pin base socket contacts associated with a second pole, pin base socket contacts of the same polarity being electrically conductively connected to one another, characterized in that in a recess (15) immediately below plug lead-throughs (14) on the non-earth-contact plug cup (3b) and within the cover plate (1b) first cover plate socket contacts (7) associated with a first pole and second cover plate socket contacts (8) associated with a second pole are arranged, the cover plate socket contacts (7, 8) which are in each case the same polarity, being connected to one another in one piece and are electrically conductively connected via plug elements (5b) moulded on in each case to the electrically associated pin base socket contacts, that plug lead-throughs (6) present in the earth-contact plug cup (2b) are flush with the pin base socket contacts in each case electrically associated with them, that a second stop level (12b) used as stop for the all-insulated second plugs is farther distant from the surface of the wall (11) than a first stop level (13b) used as stop for the first plug with earth contact, in which arrangement the stop levels (12b, 13b) are parallel both with respect to one another and to the wall (11) and that the circular plug lead-throughs (14) of the non-earth-contact plug cup (3b) exhibit a smaller diameter than the circular plug lead-throughs (6) of the earth-contact plug cup (2b).
