Description

Adapter for busbars

The present invention relates to an adapter for busbars according to the preamble of claim 1.

Such a device is already known from DE 297 08 690 U1. A housing for consumer feeder modules is described here, which is used to hold electronics for connection to three-phase consumers and signal lines. However, due to the lateral mounting of the housing having the electronics, it is disadvantageous that valuable installation space is lost within the control cabinet.

The invention has for its object to provide such a device, which is improved on the one hand in terms of the required space and on the other hand in terms of manageability and flexible functionality.

This object is achieved according to the invention by the characterizing features of the dependent claims. The adapter according to the invention is preferably used in the installation of low-voltage switchgear within installation distributors, with the device being built up in depth and height, which saves valuable space within a control cabinet. This is achieved according to the invention by an electronics module which is arranged in a plane between the busbar and the plane in which the installation devices are mounted on the busbar adapter. In an extension of the invention, the electronics module is pivotally arranged on the busbar adapter. This has the advantage that installation devices can be installed more easily and the electronics located within the module, for example in the form of an electronic circuit board, can be exchanged very conveniently. In a preferred embodiment of the invention, the busbar adapters according to the invention have a connection option for a three-bus line system, a first bus line for the transmission of logic signals, a second bus line for the transmission of auxiliary energy for the Installation devices and a third bus line is used to transmit a further auxiliary power for the installation devices and preferably one of the auxiliary power bus lines can be switched off via an emergency stop device.

Further advantages and refinements of the subject matter according to the invention are contained in the subclaims and in the description of the figures.

Show it:

Figure 1-4 the adapter according to the invention in possible different embodiments of the invention in perspective view, and Figure 5 shows a connection module for bus lines.

The adapter shown in FIG. 1 essentially consists of a base body 2 made of insulating material, contact means 4 arranged within the base body 2 for drawing current from busbars 6 and fastening means for clamping the adapter to the busbars 6. The adapter also has intelligent means 8 with connection means 10 for the purpose of data exchange between installation devices mounted on the adapter and other devices, such as electrical consumers in the form of three-phase motors or control devices, such as programmable logic controllers or the like. In one possible embodiment of the invention, the adapter is essentially in two parts and consists of the base body 2 with a drawer-like receptacle 11 and a module 12 that can be inserted into the receptacle 11 and has the intelligent means 8.

In a further embodiment of the invention, shown in FIG

Base body 2, on its side facing away from the busbars 6, the module 12, which has the intelligent means 8, is pivotably arranged. The module 12 is advantageously connected to the base body 2 on one of the two narrow sides on the side of the base body 2 facing away from the busbars 6. The module 12 is preferably detachably connected to the base body 2 and has a groove 14 on its underside for attachment to a top-hat rail. In a preferred embodiment of the invention shown in FIG. 3, the module 12 is formed at least in two parts and essentially consists of a module drawer 16 which is pivotally connected to the base body 2 and an intelligent means 8 and connection means 10 for data exchange into the Module drawer 16 insertable electronics unit 18. Furthermore, instead of or in addition to the intelligent means 8, switching means such as coupling relays or the like are to be arranged in the module drawer 16. The electronics unit 18 is fastened, for example, by means of a ratchet or snap-in connection and / or by means of a screw connection in the module drawer 16 and advantageously also has a groove 14 for fastening on a top-hat rail. As a result, the electronics unit 18 can alternatively also be mounted individually on a top-hat rail. Furthermore, it is conceivable to also design the electronics unit 18 in two parts, the intelligent means 8, which, for example, consist of an electronics board located in a housing, being designed via an interface with separate connection means 10. This also makes it possible to position the connection means 10 at different points in the electronics unit or the module 12. The connecting means 10 can then, as shown, be connected directly to the intelligent means 8 on the end facing away from the pivotable end of the electronics unit 18 or the module 12, or else in the region of the pivotable end itself, for example, also indirectly via the module drawer 16 (not shown).

In order to ensure the most flexible use of the adapter, the connection means 10 are available in a variety of forms, e.g. as standard plug and / or screw terminals and / or bus connections. In a two-part design of the module 12, it is also provided to provide various types of interchangeable connection means 10, so that an appropriate connection block can be selected depending on the type of connection required (terminals, plug, bus or mixed connection types). In addition, the connection means 10 preferably also have contact means 20 for the electrical

Connection to an adjacent module 12. The adjacent module 12 can be designed as a so-called empty module without intelligent means 8 and only serve to expand the connection means 10. The contact means 20 are For example, on one side of the module 12 in the area of the connection means 10 as spring pins and on the opposite side as a cooperating with the spring pins of an adjacent module 12 contact receptacles so that when a module 12 is inserted or swiveled in, the module 12 is automatically contacted with adjacent modules 12.

In general, in the above-mentioned contexts, connection means 10 in addition to the terminal plug-in and bus connections and the contact means are also understood to be display means for status display (e.g. LEDs or the like). In particular, AS-i bus line connections in known penetration technology are also provided as connection means 10. The groove-like guides for the form-coded bus lines, including the contacting means for the bus lines, can be integrated in the connection block having the connection means 10. In another embodiment, the groove-like guides for the AS-i bus lines can also be formed in the base body 2 and only the contacting means in the

The connection block must be integrated in such a way that contact is made with the AS-i bus line when the module 12 is folded in. When the module 12 is in the folded state, it is preferably secured to the base body 2 via a snap-in connection. In the illustrated embodiment of the adapter, supply lines for connection to the installation devices mounted on the adapter are provided on a narrow side of the base body 2, connected to the busbars 6. These supply lines can also preferably be connected to the adapter or to the contact means 4 located in the adapter via a plug-in or screwable connection block 24. The installation devices are still connected with their control and signal connections via flexible lines via the connection means 10 to the intelligent means 8 of the module 12.

For the purpose of fastening assembly means for fastening the

Installation devices on the adapter, the base body 2 and the module 12 or the module drawer 16 each have two holes or on the side facing away from the busbars 6 transverse to the direction of the busbars 6 Thread rows on. For the lateral attachment of further devices, the side surfaces of the base body 2 and / or of the module 12 or the module drawer 16 are formed with grooves 22 in particular in the form of dovetails. In a development of the invention, the module 12 has integrated current transformers 26 for monitoring the supply lines of the installed installation devices.

According to FIG. 4, the adapter has connection means 10 for at least three bus lines 28a, 28b, 28c, the first bus line 28a as a logic bus, the second bus line 28b as an energy bus for transmitting auxiliary energy for electrical devices such as installation devices and the third bus line 28c as a further one The power bus is used to transmit a further auxiliary power for the electrical devices, which is only available until an emergency shutdown occurs, for example by means of an emergency stop command device, as a result of a safety-critical situation. By switching off this additional auxiliary energy, the operating means to be controlled by the devices, for example a motor drive, are immediately transferred to a safety state via the control elements of the devices or installation devices.

Electrical devices in the form of installation devices, in this case a motor starter combination consisting of a contactor and a motor protection switch, are mounted on the adapter, the electrical connections not being shown for reasons of simplification. A connection module 30 for bus lines is used in the base body 2.

5, the connection module 30 consists of a cover part 32, an intermediate part 34 and a receiving part 36. In the intermediate part 34, three pairs of two electrically conductive parts 38 are inserted. The intermediate part 34 is inserted with the conductive parts 38 into the receiving part 36. In the intermediate part 34, three continuous recesses 40a, 40b, 40c are formed. The conductive parts 38 each consist at one end of tapering and protruding from the recesses 40a, 40b, 40c connection means 39, at the other end of a receiving contact 42 and a connecting both ends Intermediate piece 44. Three bus lines 28a, 28b, 28c are inserted into the recesses 40a, 40b, 40c, the insulation of which is penetrated by the connecting means 39, and are fixed when the cover part 32 is put in place. The receiving contacts 42 run into socket-like openings 46 in the intermediate part 34, which in turn are aligned with openings 48 in the cover part 32 when the cover part 32 is in place.

4, a contact module 50 is used in module 12, which has three pairs of first to third slots 52a, 52b and 52c, which are populated with two pairs of pin-shaped contacts 54. When the adapter is closed by swiveling the module 12 together with the base body 2, the contact means, consisting of the pin-shaped and the receiving contacts 54 and 42, come into connection, so that a connection between two of the bus lines 28a, 28b, 28c and the Module 12 is made for forwarding or processing.

If a large number of electrical devices are networked via several adapters via the bus system, then all three bus lines 28a, 28b 28c are looped through the adapters. In general, all devices are coupled to the first bus line 28a via their respective adapters, but a first group of adapters only transfers the auxiliary power of the second bus line 28b and the remaining second group of adapters only the auxiliary power of the third bus line 28c to their respective devices. In the event of an emergency shutdown, the devices belonging to the second group are transferred to a safe state immediately and independently of the current logical state of the bus system, while the state of the devices belonging to the first group is changed solely via the logic bus.

The adapter is equipped for one or the other case in such a way that either the second slots 52b (for connecting to the second bus line 28b) or the third slots 52c (for connecting to the third bus line 28c) are occupied by pin-shaped contacts 54 while the other slots 52c and 52b remain free. In general, the first slots 52a are always populated with pin-shaped contacts 54 for coupling to the first bus line 28a. The adapter can be converted in a first way by repositioning the pin-shaped contacts 54 between the second and third slots 52b and 52c. Another possibility for retrofitting is that two interchangeable versions of the contact module 50 are available, the first and second slots 52a, 52b in the first embodiment and pin-shaped contacts 54 in the second embodiment the first and third slots 52a, 52c are. A third possibility of retrofitting results on the one hand from a corresponding arrangement of openings 46 and

Openings 48 in the connection module 30 and, on the other hand, the slots 52a, 52b and 52c in a contact module 50 equipped with only two pairs of pin-shaped contacts 54, which can be used in two positions in the module 12 which are offset by 180 °, so that when the position changes of the contact module 50 the connection to the other energy bus is established.

The present invention is not limited to the embodiments described above, but also encompasses all embodiments having the same effect in the sense of the invention. For example, the adapter can also be converted in such a way that the connection module 30 has only two

Has pairs of conductive parts 38 and can be converted with respect to the conductive parts 38 or comprises two versions which differ with regard to the arrangement of the conductive parts 38 or can be converted into two different positions, so that either only the first and second bus lines 28a, 28b or only that first and third bus lines 28a, 28c can be contacted by connection means 39, three pairs of pin-shaped contacts 54 being present in module 12. For these cases, non-separable contact means 42 and 54 are also conceivable instead of the separable contact means.

By means of such a decentralization of intelligence, conventional switching devices are easy to maintain and to control or to control remotely. Reference list
