Abstract

The electrical installation device comprises a metal supporting plate (12) which can be installed to the edge (11) of the opening of a wall box. Said supporting plate (12) is originally designed to be attached to a round wall box. To allow attachment to a larger rectangular wall box (10) an adapter plate (14) is provided which is supported on the edge of the opening (11) of the rectangular wall box (10) and comprises centering elements extending into the wall box (10). On the front side of the adapter plate (14) the supporting plate (12) is fixed, with contours (21,22) on the edge of the supporting plate (12) meshing with positioning means (19,20) in the adapter plate (14) such that both plates are fixed relatively to each other. In this way it is possible to use an installation device designed for relatively small round wall boxes in combination with a relatively large rectangular wall box.

Description

Electrical installation device

Technical field

The present invention relates to the electrical installation device in a kind of wall boxing that will be inserted into rectangle.

Background technology

Described erecting device is electrical socket, switch, lampshade and other device that can be installed in the standard wall boxing.

The standard of wall boxing and erecting device is inter-State different.Generally use the cylindrical wall box of 40 millimeters of diameter 60 millimeters deep in Germany.Adopt the rectangle wall boxing of the inner space, the side of having of 48 millimeters of about 71 millimeters deep of the length of side in China.Be inserted into erecting device in such wall boxing and contain a metal support plate of fixing a plastic bottom board on it.The type of the configuration of described base plate and the erecting device of use is corresponding, for example socket base plate or switch baseplate.Support plate is installed in the front of corresponding wall boxing, and erecting device is fastened on the wall boxing.In German system, generally be fixing, and described hitcher also is used for launching to make it to embrace wall boxing by screw with the hitcher that is bearing on the base plate.In Chinese system, described wall boxing contains the securing member of being with thread, wherein can insert screw, and screw passes support plate and support plate drawn and leans against on the wall boxing.

German and Chinese system is incompatible, thereby must make diverse wall boxing and erecting device.

Summary of the invention

An object of the present invention is to provide a kind of electric erecting device that can insert different wall boxings, thereby can produce for the system of country variant uniformly.

According to the present invention, a kind of erecting device is provided, it contains a metal support plate and a plastic bottom board that is fixed on the described support plate, described erecting device is used for being inserted into a round wall boxing, described erecting device is provided with an adaptation board, it is bearing on the edge of opening of the rectangle wall boxing wall boxing of Chinese system (for example corresponding to) and contains a centering device that extend in the described wall boxing, wherein, described adaptation board has an opening that is used to insert base plate, and support plate is bearing on this adaptation board.

The present invention can be used in combination in the wall boxing corresponding to Chinese Industrial Standards (CIS) the erecting device corresponding to German standard, although this erecting device does not fit in the described wall boxing.The primary element that is used for this purpose is described adaptation board, and is fixed as to make it occupy the center of rectangle wall boxing its configuration and size.Described center needs not to be a permanent center.Prevent to be shifted just enough along direction to a certain extent with the former quadrature along a direction superior displacement.Such tolerance can have the advantage of conveniently backing out screw.Described adaptation board contains the wherein opening and a front side of mounting bedplate, and it supports the rear side of described support plate.

Adaptation board needn't separately be fixed on the rectangle wall boxing.It can configuration becomes one and reinstates the screw that passes two plates with described adaptation board one and be screwed in intermediate plate on the rectangle wall boxing.

Positioner preferably is provided, and they are guaranteed to be bearing in support plate on the adaptation board and are not rotated and be not shifted, thereby adaptation board plays a part support plate or whole erection device correspondingly are completely fixed.The profile that constitutes on such positioner and the support plate edge closely cooperates, thereby makes support plate placed in the middle as just in time to be pressed on the adaptation board.

A kind of framework preferably is provided, contains a circumference flap that covers adaptation board from the side.Thereby thereby the edge of described framework evenly is pressed in and had both covered wall boxing on the wallpaper around wall or the wall boxing and also cover adaptation board and add upper bearing plate.

According to a preferred embodiment of the present invention, two parallel edges are contained in the front side of adaptation board, arrange support plate therebetween and wherein are provided with the positioner of concave form.Between the edge of protuberance, arrange support plate in the mode that sinks to.The height at edge is approximately identical with the thickness of support plate.

Can constitute socket, switch, lampshade or electronic installation according to erecting device of the present invention.
