Electric transfer module

The invention relates to an electrical transfer module with a connection for a data cable and with a plurality of electrical contact elements, via which an electrical and / or electronic connection to a corresponding number of trained as Schraubklemmanschlüssen counter-contact elements of a terminal block can be produced.

Such transfer modules are generally known and disclosed, for example, on pages 172 and 173 in the catalog "Signal Converter Interface 2005" from Phoenix Contact The known transfer modules have a connection for a data cable which is electrically connected to contact elements designed as screw terminals In each case an electrical and / or electronic connection to counter-contact elements of a terminal block can be made to the individual terminals connected to the screw terminals The terminal block comprises screw terminal connections as counter-contact elements and preferably electronics for processing the electrical and / or electronic signals received from the transfer module.

This type of electrical and / or electronic connection between the transfer module and the terminal block is considered time-consuming and prone to failure, because each conductor is to be connected individually to the associated screw terminal of the transfer module and additionally to the associated Schraubklemmanschluss the terminal block.

The remedy is provided by the transfer module disclosed on pages 182 and 183 of the "Signal Converter Interface 2005" catalog from Phoenix Contact.

In this known transfer module plug contact elements are provided for electrical and / or electronic connection to a terminal block instead of Schraubklemmanschlüsse, which are electrically connected to the connection for the data cable.

About this plug-in contact elements can be directly generated in a specially designed terminal block designed as Schraubklemmanschlüssen counter-contact elements and in addition to the plug contact elements mating contact elements an electrical connection by all plug-in contact elements of the transfer module are simultaneously introduced into the counter-contact elements designed for this purpose. Thus, a fast connection between the transfer module and the terminal block is made possible.

BESTÄTIGUNQSKOPIE The invention has for its object to provide a transfer module, which can be connected on the one hand quickly with a terminal block with Schraubklemmanschlüssen electrically and / or electronically. On the other hand, the fast electrical and / or electronic connection between the transfer module and the terminal block with s Schraubklemmanschlüssen should be possible as a counter-contact elements, without the terminal block is consuming to adapt.

The invention achieves the object with the features of patent claim 1.

Advantageous embodiments and further developments of the invention are specified in the dependent claims. o In the transfer module of the invention, the electrical contact elements of the

Transfer module are designed such that via them an electrical and / or electronic connection directly to the trained as Schraubklemmanschlüssen counter contact elements of the terminal block can be produced. The Schraubklemmanschlüsse of the invention each have exactly one clamping chamber with a pressure piece for clamping the contact element of the transfer module, wherein the electrical and / or electronic connection via the electrical contact elements with open Schraubklemmenanschlüssen can be produced and the contact elements are designed such that the electrical and / or electronic connection to the pressure piece can be produced. 0 Through this adaptation of the electrical contact elements of the transfer module to the

Screw terminal connections can easily be made to terminal blocks with Schraubklemmanschlüssen a fast electrical and / or electronic connection between the transfer module and the terminal block. For this, no change in the terminal block is required because the contacts of the transfer module can be connected directly to the Schraubklemmanschlüsses. An electrical conductor is thus not necessary for the electrical and / or electronic connection to the terminal block with Schraubklemmanschlüssen. The transfer module according to the invention can be universally used by its adapted contact elements. It can thus be used with any terminal block with screw connections. The use is independent of whether there is an additional connection possibility, for example, through bridge shafts or not.

Characterized in that the individual contact element of the transfer module designed such that the electrical and / or electronic connection via the contact elements of the transfer module with open Schraubklemmenanschlüssen can be produced, eliminating the screwing in the screw for clamping the contact to be connected. 5 In an advantageous further development of the invention, it is provided that the electrical contact elements each have at least one flat planar section, which rests against a planar section of an electrically conductive part of the associated Schraubklemmanschlusses in the electrical and / or electronic connection. This adaptation of the geometry of the contact element to that of the conductive part ensures that contact resistance is small.

So that the electrical and / or electronic connection between the contact elements and the Schraubklemmanschlüssen can be permanently ensured, it is provided that the contact elements are resiliently configured so that they press against the electrically conductive part of Schraubschraemmanschlusses in the electrical and / or electronic connection.

A secure contact is additionally produced by a latching of the transfer module to the terminal block. Thus, from a conventional Schraubklemmanschluss a pluggable baseboard, so that a direct plug-connector system is provided. As a result, on the one hand, a fast and secure electrical and / or electronic connection as well as a secure mechanical connection are produced by the transfer module to the terminal block.

To achieve a stable, positive connection of the contact element to the Schraubklemmanschluss, it is provided that the contact elements are at least partially stored in a U-shaped receiving space and at least partially surrounded by its walls and protected.

Preferably, the contact elements dive with the respective receiving space in the electrical and / or electronic connection in the clamping chamber of Schraubklemmanschlüsse. This makes it possible to use narrow contact elements, without the risk that they bend during insertion into the clamping chamber.

In an advantageous embodiment of the invention it is provided that the contact elements comprise a wedge-shaped bent sheet metal strip having a first leg and a second leg and are configured such that in the electrical and / or electronic connection between the contact elements and the counter-contact elements, the first leg Press the sheet metal strip resiliently against an electrically conductive part of the Schraubklemmanschlusses. This sheet metal strip is mechanically stable and easy to produce in the bending process. Thus, the contact element formed as a sheet-metal strip having the necessary contact force against the electrically conductive part of Schraubklemmanschlusses, on the first leg, a third leg is formed such that it limits the spring travel of the first leg. The limitation of the spring travel can, for example, be achieved in a simple manner in that the third leg points from the first leg in the direction of the second leg. This ensures that the first leg is supported via the third leg on the second leg corresponding pressure on the first leg in the direction of the second leg.

Thus, it is clear that the wedge-shaped sheet metal stiffening significantly stiffened when it is pressed into the clamping chamber of a screw terminal.

Thus, the necessary contact pressure is given to the metallic pressure piece, because the stiffening of the resilient wedge shape is effected by the spring travel.

According to an advantageous development, the transfer module on its housing hooks for locking with the terminal block, which can be actuated by means of an unlocking and / or ejection device which is provided on the housing as an actuating lever.

An embodiment of the invention is shown purely schematically in the drawings and will be described in more detail below. It shows:

Figure 5 shows another embodiment, also in the sectional view of the

Approach of a transfer module;

FIG. 6 shows a further detailed view according to FIG. 4 FIG. 7 shows another view of an attached transfer module according to FIG. 2 in another view

and

8 shows another connected to a terminal block transfer module with additionally provided covers.

Figures 1 and 2 show a transfer module 1 with a connector in the form of a header for a data cable, not shown. The transfer module 1 has a multiplicity of electrical contact elements 5, via which an electrical and / or electronic connection to a corresponding number of counter-contact elements of a terminal block 2 designed as screw terminal connections 4 can be produced.

Each Schraubklemmanschluss 4 is exactly one clamping chamber 8 associated with a pressure piece 6 for clamping a contact element 5.

The contact elements 5 of the transfer module 1 are arranged perpendicular to the connection 20 for the data cable in two superimposed rows.

When electrically and / or electronically connecting the contact elements 5 of the transfer module 1 as shown in the sectional view of Figure 2 in the Schraubklemmanschlüsse 4 of the terminal block 2 a.

As FIGS. 4, 5 and 6 show particularly clearly, each individual screw terminal 4 comprises a clamping chamber 8 with a pressure piece 6 made of an electrically conductive material and a clamping screw 7.

According to the invention, it is provided that the electrical contact elements 5 of the transfer module 1 are designed such that an electrical and / or electronic connection can be made directly to the counter contact elements of the terminal block 2 that are designed as screw terminal connections 4. Due to this special design of the contact elements 5 there is no longer the need to clamp the contact elements 5 by pressing the clamping screw 7 via the pressure piece 6 in the clamping chamber 8. It is preferably provided that the electrical and / or electronic connection via the electrical contact elements 5 with open Schraubklemmenanschlüssen 4 can be produced. Particularly suitable as contact elements 5 are plug-in contact elements. In order to achieve in particular the mechanical connection for the contact element 5, the contact elements 5 are at least partially supported in a U-shaped receiving space 10 and at least partially surrounded by the walls 13, 14 and protected.

The contact elements 5 are each at least partially guided in the U-shaped receiving space 10 s, wherein the contact elements 5 dive with the respective receiving space 10 in the electrical and / or electronic connection in the Schraubklemmanschlüsse 4.

The U-shaped receiving chamber 10 occurs in the inserted or inserted state in positive engagement with the chamber walls of the clamping chamber 8. Thus, a guided, tilt-safe secure mechanical connector is created. In this case, the lo receiving space 10 is slightly tapered at its free end, as is also clear in Figure 4. The tapered design has the particular advantage that the contact element 5 for the preparation of the electrical connection in the clamping chamber 8 has sufficient space to be able to freely contact the overhead pressure piece 6 and here in particular with its underside.

In order to produce the electrical connection, the contact element 5 is resilient at least in one area. As a result, the contact element 5 automatically comes into electrical contact with the electrically conductive pressure piece 6 when electrically and / or electronically connected. As is clear from FIGS. 4, 5 and 6, the resiliently formed contact element 5 is formed from a longitudinally shaped sheet metal strip 12 which in the U-

20-shaped receiving space 10 and is guided out here between the walls 13 and 14. The metal strip 12 is wedge-shaped in cross section. It has a first leg 16 and a second leg 17 and is configured such that in the electrical and / or electronic connection between serving as a contact element 5 sheet metal strip 12 and the counter-contact element of the first leg 16 of the metal strip 12th

25 resiliently against an electrically conductive part, for example. The pressure piece 6, the Schraubklemmanschlusses 4 presses.

As can be seen in particular from FIGS. 4 and 5, but also from FIG. 6, a third leg 18 is integrally formed at the end of the first leg 16. It points in the direction of the second leg 17 and supports the leg 16 against the second leg 17. The 0 third leg 18 thus limits the travel of the first leg 16 in the direction of the second leg 17. Thus, a stiffening of the resilient acting as a contact element 5 wedge-shaped sheet metal strip 12 when inserted into the clamping chamber 8, as soon as the third leg 18 on the second leg 17th encounters. Consequently, the sufficient contact pressure against the pressure piece 6 or here against the underside of the pressure piece 6 at 5 relieved clamping screw 7, so that a self-holding contact of the

Transfer module 1 is brought to the terminal block 2. This will be even more supports that, for example, 6 corrugations are provided on the underside of the pressure piece, which prevent an automatic unintentional falling out of the transfer module 1.

As can still be seen from FIG. 4, the second legs 17 of the metal strips 12 are introduced into the housing of the transfer module 1 in such a way that they are connected to the terminal 20 via a printed circuit board 19 mounted in the housing and interconnected.

In a further development of the invention, as shown in FIGS. 1, 2 and 7, hooks 21 for latching the transfer module 1 to the terminal block 2 are provided on the housing of the transfer module 1. This locking represents a possibility of mounting the transfer module 1 to the terminal block 2. In this case, the hooks 21 cooperate with an unlocking and / or ejection device. The unlocking and / or.

Ejector can be actuated from the outside of the housing, for example. Via a lever 22, so that transfer module 1 can be solved by the terminal block 2.
