Description

The invention relates to a socket box with an elongated housing made of plastic formed from a bottom cover and a detachably connected, hood-shaped upper part, on the upper part opposite protruding plug device support plates in pot or plate form for arranged in the housing by installation wiring with at least A plug-in connector is connected to electrically connected sockets and / or switches and / or safety device carriers and / or communication inserts and the protruding connector plates are encased in a latched cover frame, and contact blocks with their protective contacts and contact sockets can be moved in the longitudinal and / or transverse direction on the bottom cover under the connector plates are fixed.

A socket box has become known from AT-B-374 977, in which plug insertion pots are formed in one piece in the shell-shaped upper part and socket inserts (contact blocks) are arranged below these plug insertion pots, which are formed by means of molded on the underside of the upper part and in corresponding recesses of the sockets -Inserting pegs are locked in position and fixed in the socket box by screws or rivets for connecting the upper and lower parts of the housing.

The pins and recesses are matched to one another in such a way that only a specific insertion position of all socket inserts in the socket box is possible.

Furthermore, from EP-A-0 379 662 a socket box is known, in which the sockets with their pots are used as separate components in recesses in the hood-shaped upper part and are fixed in position by a latching cover frame or by screws in the socket box. Current conductors and ground conductors in strip form are fixed on the bottom cover, with which the sockets can be contacted with contact lugs and a grounding contact in several axially rotated use positions.

The object of the invention is, based on this last-mentioned prior art, to improve a socket box in such a way that the contact blocks can be fixed in a few simple steps in a number of axially rotated operating positions in the socket box without additional fastening means, by simple and inexpensive manufacture of the socket box housing parts.

This object is achieved by the characterizing features of claim 1. The subsequent subclaims contain design features which represent advantageous and beneficial further developments of the task solution.

In the socket box according to the invention, the contact blocks are fixed in position in several axially rotated positions in the socket box by manufacturing molded on the bottom cover or the pot-shaped plug device support plates of the upper part and engaging in jacket-side recesses of the contact blocks. The contact stones are inserted in the desired position on the bottom cover between the bottom cover-side fixing parts or with their jacket-side recesses between the fixing parts of the upper part, so that they can be locked in the desired position in a few simple steps and Bottom cover inserted between the bottom cover-side fixing parts or with its jacket-side recesses between the fixing parts of the upper part, so that they can be locked in the desired position with a few hand movements and fixed without additional fastening means between the bottom cover and the pot-shaped plug-in support plates.

In this strip-shaped socket box, all common sockets according to European standards and earthed sockets can be easily inserted and fixed by the molded fixing parts and are easy to install.

The contacts of the sockets are to be arranged either in the longitudinal and transverse directions or in the diagonal direction or other intermediate degrees of the socket box, which is determined when the plug-in device support plates are molded on, and the contact blocks are then twisted accordingly in the box by the fixing means; this enables a variable type of insertion for the connector.

Furthermore, the connector (s) and / or the contact blocks can be molded in a simple and cost-effective manner on the base part of the socket box and can be equipped with conventional contacts.

The plug-in support plates in the form of a pot or plate are molded onto the upper part in a simple and cost-effective manner and are gripped and covered flush at their edge projecting over the upper part by a clipped-on cover frame.

This socket box forms a cavity wall socket for accommodating the various electrical devices and for various uses in industry, office, household or the like.

The socket box has an elongated plastic housing formed from a bottom cover (bottom part) (1) and a hood-shaped upper part (2) detachably connected to it, in which one or more sockets (3) and / or switches and / or safety device carriers ( 4) and / or communication inserts (5) and at least one connector (6) electrically connected to it by installation wiring. The sockets (3) and / or security device supports (4) and / or communication inserts (5) are surrounded on the access side by a cover frame (7) which is detachably held on the upper part (2).

The plug-in device support plates (8, 9) in the form of a pot or plate of the sockets (3) and / or security device support (4) and / or communication inserts (5) are molded onto the upper part (2) and these plug-in device support plates (1) are integrated with the upper part (2). 8,9) are covered by the cover frame (7) which is locked with it.

The pot-shaped plug-in support plates (8) are formed with their bottom-side through holes (10) for the plug contact pins and jacket-side openings (11) for the protective contacts (12) of the contact blocks (13) arranged in the longitudinal and / or transverse direction on the upper part (2) and the contact blocks (13) with their contact sockets (14) are fixed accordingly on the base cover (1).

The contact blocks (13) can be arranged with their contact sockets (14) and protective contacts (12), preferably offset by 90 degrees (rotatable) on the bottom cover (1) and are by means of on the bottom cover (1) and / or on the pot-shaped plug-in support plates ( 8) molded, in the jacket-side recesses (15) of the contact blocks (13) engaging fixing parts (16) in the form of pins, webs, domes or the like.
