Description

Wiring system for control and signaling devices

The invention relates to a wiring system according to the preamble of claim 1.

Command and signaling devices, such as those shown and described in DE-U 93 18 965 or DE-U-93 05 527, require considerable wiring effort.

One option for "classic" or "conventional" wiring is shown and described in DE-Al 42 910. It consists of laying cables directly between control and signaling devices and, for example, contactors or auxiliary switches.

Conventional wiring to networkable programmable logic controllers or external modules is also known.

Simplified wiring using a so-called circuit board adapter is also known. However, this has the disadvantage of a fixed configuration in a predetermined grid.

It is also known to connect devices to a bus, as described in DE-C 39 42 390, DE-A 42 16 242, DE-A 42 17 066, DE-A 42 25 834, DE 41 42 254 A or GM 93 11 707.

The object of the invention is therefore to create a wiring system according to the preamble of claim 1, which enables simple, fast, safe and clear wiring.

The object of the invention is achieved by the characterizing features of claim 1, while the subclaims contain particularly advantageous developments of the invention.

Marked are.

The invention and the advantageous embodiments of the invention result in the advantage that no wiring errors are possible while allowing for individual and clear wiring.

Another advantage is that the connectors can be easily plugged together without the need for an assembly tool for the connection.

Wiring security is increased by coded connectors.

It is particularly advantageous that standard connectors and standard cables can be used.

A particular advantage is that the customer does not need to store the cable.

It is also possible to carry out a test setup with little effort, which simplifies commissioning.

The wiring system is particularly easy to maintain because the control and signaling devices can be easily replaced without interrupting the bus.

Another advantage is that there is no mechanical stress on the control or signaling device.

Fig. 5 is an alternative to Fig. 2.

Figure 1 shows the contacting of a command or signaling device in the form of an adapter 5. This adapter 5 contains a circuit board with a bus connection.

The wiring system for control and signaling devices consists of several electromechanical control devices or signaling devices, each of which has a head 2 arranged above a control panel or front plate for operation or display.

Furthermore, the control or signaling device has a shaft 3 that can be inserted through the control panel or front panel and a screwable fastening ring 4b.

The plug connections 4 are connected to a coupling adapter 6, whereby the coupling adapter is suitable as a direct electrical and mechanical connection of conventional, bus-incapable control devices or signaling devices

The control devices or signaling devices 1 have plug connections 4 below the control panel or front plate - on the opposite side of the head 2. The plug connections 4 can be connected to an adapter 5, which takes on the function of a bus participant, as can be seen from Fig. 2. The adapter also has wiring lines 7, which can be plugged into a bus or ring.

The plug-in direction (A) of the adapter 5 is perpendicular to the mounting plane, as indicated in Fig. 1.

The wiring lines 7 are firmly connected to the adapter 5, whereby the adapter 5 has a first bus line section 7a with a bus plug 8 and a second bus line section 7b with a bus socket 9.

As Figures 4 and 5 show, the adapter 5 can alternatively have a bus line section 7a with a bus plug 8 and a bus socket 9 mounted directly on the adapter 5.

As shown in Fig. 3a, the wiring system may comprise extension pieces 11 consisting of a bus line section 12, a bus plug 8 and a bus socket 9.
The wiring system may also comprise branch pieces 13 consisting of two or more bus line sections 12, two bus sockets 9 at the branch ends and a bus plug 8 at the node, as shown in Fig. 3b.

The wiring system is particularly suitable for serial data processing. This is particularly suitable for two- or three-wire buses, where individual copper wires are used as a transmission medium. A design for shielded cables or glass fibers is also possible, whereby a master-slave structure with an integrated power supply and a fieldbus connection via a gateway can be implemented.

In the figures shown, three bus lines are looped through to each participant. Another design based on two bus lines is also conceivable.

The following features are shown in the example:

Coded connectors are available.

The adapter 5 contains a circuit board with a bus connection.

The length of the bus line sections is selected so that the control and signaling devices can be mounted in a fixed grid or within a certain radius.

The bus plug 8 or bus socket 9 are connected to the bus line sections 12 directly with a circuit board located in the adapter 5.

The adapter 5 can have an addressing switch 10a, 10b, 10c. Addressing by the physical arrangement of the participants in the network is also possible.
