Description

Electrical switching and / or control device arrangement

The innovation is based on an electrical switching and / or control device arrangement according to the genre of the main claim.

In switching and control technology, it is known to switch and / or control devices in To install control cabinets. For this purpose, these devices are fitted with a quick-release clamp that can be snapped onto mounting rails or the devices are fitted with flange holes

: screwed on. if the

Switching and / or control arrangement is to be expanded, are in known designs other switching and / or control devices attached to the mounting rails, the devices not mechanically coupled with each other, but only electrically by means of individual

Conductors or with ribbon cables and connectors

tied together. Another embodiment provides that, for example, sockets in a Rail are arranged and the individual devices to be connected have plugs, which are plugged into the sockets. The individual sockets are via a Bus circuit board interconnected. The disadvantage of these known designs is that the devices are not mechanically coupled and that the electrical connection is very expensive and labor-intensive or requires a large amount of space.

The task of the innovation is therefore to develop housings for electrical switching and control devices, which in a simple manner to any number of housing arrangements, which are mechanically and electrically connected, can be plugged together. When plugging together the devices should be directly connected mechanically and electrically.

According to the innovation, this object is achieved by the characterizing features of the main claim solved in connection with the features of the preamble.

Due to the mechanical connection via the centering pins, which are force-locked in the housing are held, the housings are securely connected to each other to save space. The electrical connection is made in a simple manner via the double pin headers, so that no cables hanging around are necessary.

The measures specified in the subclaims are advantageous developments and improvements possible. It is particularly advantageous that in each case the sockets for a double pin header and for a centering pin together on one circuit board are arranged, whereby the centering with each other is improved.

An execution example of the innovation is shown in the drawing and is explained in more detail in the following description. The only figure shows two Housing for an electrical switching and / or control device arrangement with the centering pins and the double socket strips for the electrical and mechanical connection.

In the figure, two housings 1, 2 are shown, the circuit boards with electrical Components, for example for an electrical control and / or switching relays and terminals take up. In the side walls of the housing 1.2 openings 3.4 are provided behind them sockets for the mechanical and electrical connection of the Housing are below each other. These openings 3, 4 are shaped accordingly Parts can be locked if further expansion of the arrangement is not desired is. Centering pins 5 are provided for the mechanical connection between the housings 1, 2, through the openings 4 both from the r \ er side of the housing 1 and from the side of the housing 2 in the in the housings 1, 2

sockets included. Both end parts of the centering pins 5 are provided with grooves, snap into the springs contained in the sockets, so that the Centering pins 5 are held positively in the sockets.

Behind the elongated openings 3 are located inside the housing 1, 2 as Plug strips formed electrical sockets into which the between the two housings 1.2 shown double pin headers 6 can be inserted. The sockets can inside the housing 1, 2 on the side walls, on strips or on the circuit boards be attached. It is advantageous if there is one socket for a double pin header and a socket for a centering pin in a fixed mechanical connection with one another stand so that they are centered with one another. For example the sockets can both be arranged on a circuit board.

In the drawing, only two housings 1, 2 are shown, which are connected to one another. Of course, the devices can be expanded as required on either side.
