Description

The present invention is based on a designed according to the preamble of the main claim electrical socket for building installation technology.

Such electrical sockets are usually intended to produce an easily re-separable electrically conductive connection to a consumer as needed via an appropriately designed plug and optionally an electrical line connected thereto. Often, such electrical plug devices are provided with a contact protection device, which offers an increased contact protection. Often, such contact protection devices are also referred to as child safety. The increased contact protection is realized by the use of a blocking element, which may be formed, for example, as a sliding piece, as a rotating piece and so on. Such, cooperating with at least one spring means blocking element automatically shields the live contact parts of the electrical connector or locks associated plug openings as soon as the plug was pulled out of the electrical outlet. The contact protection device is designed so that an insertion of other objects (foreign objects) is effectively prevented than the insertion of a permissible type of plug, the blocking element is in its blocking position. Only when inserting a suitable or permissible type of connector, the blocking element is pushed aside in a simple manner and thus releases the connector openings, so that the connector pins of the appropriate or permissible type of connector can properly contact the contact parts of the connector.

An electrical socket corresponding to the preamble of the main claim for the building installation technology has become known through the electrical socket Socket insert British Standard 1363 Albrecht Jung GmbH & Co. KG (Catalog Export 26, page 253 from 2015). This electrical socket is provided for connection of a plurality of plug pins having plug, wherein the electrical socket has a necessary for contacting the plug pins and the electrical cable contact parts receiving, provided with a carrier socket part.
