Description

The invention relates to a terminal block according to the preamble of claim 1.

Such terminal blocks are provided for connecting electrical conductors. In this case, a bare end of a conductor is fixed in a terminal, which is electrically conductively connected via a conductor element with another terminal or a connector. At the other terminal or the connector another electrical conductor can be connected in a corresponding manner. The document EP 0 763 874 A2 shows an electrical Etagenklernme with two busbars, which are electrically connected to each other with an electrically conductive bridge.

In order to provide a small amount of space, e.g. In a control cabinet or a terminal box, to provide a plurality of terminals, so-called double-level terminals are used as terminal blocks.

An example of such a clamp is described in the document DE 25 39 250 A1 , wherein a terminal base has on its upper side a design as a support rail segment for applying a further conventional terminal. The documents DE 295 14 711 U1 and EP 1 555 726 A1 show terminal blocks, each having a lower part with electrical terminals on which an upper part with one or more electrical terminals is fixed.

The publication DE 20 2008 015 306 U1 shows a terminal block assembly of several terminal blocks and a test plug, either with a busbar one of the terminal blocks, or a cross connector for connecting the busbars of a plurality of the terminal blocks is contactable.

A continuously increasing demand for such terminal blocks, e.g. in automation areas, results in the demand for smaller number of parts, as equal as possible components, small size and flexible design.

The object of the present invention is therefore to provide an improved terminal block.

The object is achieved by a terminal blocks with the features of claim 1.

The terminal is formed with an upper part and a lower part with a respective conductor element, which in a first embodiment are removably connectable to each other again. The upper part and the lower part form, so to speak, each separate terminal blocks, but which are connectable to each other.

They each have one or more conductor connection elements, such as connection terminals, which are connected to one another by the conductor element, such as a busbar. One or more of the conductor connection elements can also be replaced by connection elements such as pins or sockets.

Preferably, in any case, the upper part in the direction of arrangement are provided on both sides with insulating walls, so that it is also possible to set up a single shell only on a single row of parts only at one point, without the end angle or the like. Are required.

The fixation of the upper part on the lower part at least in the direction of arrangement can be done by swords or the like. Or by other means such as the vertical connector.

According to an advantageous variant - which is also kinematically reversible - the upper part can be inserted into the lower part. Thus, the terminal blocks can be extended in any extent in a simple manner, with a particular advantage is that the upper part is held firmly in the lower part not only in the longitudinal direction, transverse direction and height direction of the terminal, but is also lockable and this locking means of a tool , eg Screwdriver blade, is again detachable.

A connection of the conductor elements in the upper part and lower part is effected by at least one plug-in and again releasable vertical connector, which connects the conductor element of the lower part and the conductor element of the upper part electrically conductive and possibly also mechanically by simply plugging. Thereby In a simple way, a vertical connector is used to conductively connect the upper part and the lower part with each other.

Here, the at least one vertical connector can be guided in vertical channels in the lower part and in the upper part. This ensures a simple and safe threading and joining.

One advantage is that the upper part can have at least one guide blade, which can be inserted and pushed into the designated at least one corresponding guide groove of the lower part without excessive force. Snapping as in the prior art is not required.

Yet another advantage is provided by the fact that the conductor elements can be electrically connected by means of a vertical connector.

Due to the guide groove and thus existing centering the upper part is fixed immediately in the longitudinal direction of the mounting rail or mounting rail and requires no alignment in this longitudinal direction more.

In addition, the upper part is lockable with the lower part, which can be done for example by means of at least one latching hook, which can be mounted next to the at least one guide blade so that it has a necessary suspension for locking.

For this purpose, the at least one latching hook may have a latching element, for example in the form of a hook, which can be releasably locked with an opening with an undercut in a wall of the lower part.

For simultaneous centering during assembly, the upper part can be provided with at least one centering element, which cooperates with at least one centering receptacle of the lower part corresponding to it. That's one easy and easy assembly guaranteed. By locking the latching hook a secure and fast grip is possible.

These electrical connections are created by plugging in. In this case, the at least one vertical connector having an upper part connection and a lower part connection, which form an electrical connection by contacting with the respective conductor element in the respective contact opening by resilient contact pressure and / or cutting sections.

In a further embodiment, the conductor element of the lower part can be designed for a potential grounding.

A further advantage results from the fact that the terminal block can form four different versions, namely through terminal upper part and through terminal lower part, through terminal upper part and PE terminal (potential ground) lower part, connection via vertical connector of upper part and lower part, and connection via vertical connector of upper part and lower part as a common PE terminal.

In addition, cross-connector can be provided to adjacent terminal blocks, which can also be electrically connected to the vertical connectors, so that there is a great variety of connectivity options with small number of parts and small space.

The upper part and the lower part can also be themselves parts of a more than two-storey design, as well as three or more levels of "upper and lower parts" or successive settable terminal blocks can be realized.

Also conceivable are optional coding means between upper part and lower part.

The lower part body 2a has at its center a channel dome 28, which here has a rectangular cross section and extends from the central portion 14 of the conduit member 13 to the top of the lower part body 2a. On its upper side, two guide cheeks 27, which extend in the x-direction and taper upwards in the z-direction, are integrally formed on the channel mandrel 28. Within the channel dome 28, a vertical channel 7 is formed, the upper opening is located between the guide cheeks 27. The vertical channel 7 extends in the z-direction, ie in the vertical direction of the lower part body 2a, to a lower opening in the channel mandrel 28, which extends above the central portion 14 of the duct element 13 and is aligned with the contact opening 15 of the central portion 14. Below the contact opening 15, a V-shaped connector receptacle 29 is formed in the attachment portion 10. Their function and the function of the vertical channel 7 will be described in more detail below.

Left and right in the y-direction of the channel mandrel 28, a centering receptacle 6 is in each case formed in the lower part body 2a, which has a general U-shape. At this Zentrieraufnahmen 6, which are explained in more detail below, joins left and right in the y-direction in each case a guide groove 5 with a substantially rectangular cross-section. Each guide groove 5 is formed by the top wall 3, the front wall 4 and two transverse walls 9. It can be open at the bottom, partially open or closed. Each guide groove 5 also has a portion hook guide 5a, which is provided at its lower end with an opening with an undercut 5b. In Fig. 1 the hook guide 5a is arranged on the left side of the guide groove 5, the opening with the undercut 5b being arranged in the front wall 4. The hook guide 5a of the right guide groove 5 is located on the right side of the guide groove 5, wherein the opening with the undercut 5b is in the top wall 4, as in the Fig. 7 can be seen.

The guide grooves 5 with the hook guides 5a and the centering 6 serve to receive and guide a shell 20 which is connectable to the lower part 2 by being removably inserted and lockable to the lower part 2. This shows Fig. 2 a schematic perspective side view of an embodiment of the upper part 20 of the terminal block according to the invention. 1

The upper part 20 has the same dimension in the x-direction as the lower part 2, but is shorter in its length dimension in the y-direction than the lower part 2. Further, the upper part 20 has similar components and sections as the lower part 2, which with the corresponding Reference numerals are provided with an apostrophe "'".

The upper part 20 in turn has the at least one conductor element 13 'and at least one or more terminals connected thereto for external conductors or plugs.

An upper body 20a has a connection side A 'with an insertion shaft 11', a clamp 18 ', a clamping element 19', an actuating shaft 12 'and an identification section 39'. A connector side B 'serves to receive a connector with a connector receptacle 8'. In this case, a top wall 3 'and a front wall 4' are connected by transverse walls 9 '. The connection side A 'and the connector side B' are connected by a center body 21. The underside of the upper part 20 has on both sides in each case a guide blade 22 and on the outer sides thereof in each case a latching hook 23 with a latching element 24. Guide blades 22 and latching hooks 23 are each separated by an elongated recess in the z-direction, wherein this recess extends over approximately three quarters of the length of the guide blades 22 in the z-direction and is open at the bottom. Each latching hook 23 is approximately one third as long in the y-direction as a guide blade 22 in the y-direction. The guide blades 22 and the latching hooks 23 together have a length of approximately two thirds of the total length of the upper part body 20a in the y direction in the y direction and are respectively arranged on the connection side A 'and the connector side B'.

The guide blades 22 adjacent transverse walls of the centering elements 25 extend obliquely downward in the z direction and are approximately in the middle of the length of the guide blades 22 in the z direction to Center bent in the y direction. Between the centering elements 25 is in the Fig. 2 extends the top wall 3 as a channel cover wall 26, which closes the gap between the centering elements 25 in the plane of the top wall 3 '. This is in the FIGS. 7 to 11 more clearly recognizable.

A duct element 13 'is arranged with a middle section 14' in the upper part body 20a. The central portion 14 'is provided in the region of the plug receptacle 8' with a plug portion 16 '- similar to the lower part 2 -, wherein the other end of the central portion 14 'is connected via a Z-shaped bent clamping portion 17' to the terminal 18 '.

At the top of the center body 21, two transverse walls 9 'are formed, which are beveled upwards. Between them and further left and right of them arranged transverse walls of the same height in the z direction three transverse grooves 37 are formed here. The center body 21 has a vertical channel 7 ', the upper opening between the two transverse walls 9' in the central transverse groove 37 is located. The lower opening of the vertical channel 7 'is above a contact opening 15' of the central portion 14 'of the conduit member 13', with which the lower opening of the vertical channel 7 'is aligned. Below the contact opening 15 'is the intermediate space between the two centering elements 25th

The upper part 20 can be removably inserted into the lower part 2 to form the terminal 1, ie a double-storey terminal 1. This is related to Fig. 3 and 4 described.

Fig. 3 shows a schematic perspective side view of the terminal block 1 according to the invention in the assembly of lower part 2 and upper part 20, and FIG. 4 shows in a schematic perspective side view of the bottom part 2 and top 20 assembled according to the invention terminal 1 after Fig. 3 ,

The lower part 2 is already placed with its attachment portion 10 on the support rail 38. The upper part 20 is shown here during the insertion process in the lower part 2. In this case, the connection sides A, A 'and connector sides B, B' are each on one side. The guide blades 22 and the latching hooks 23 of the upper part 20 are respectively inserted into the guide grooves 5 and hook guides 5a of the lower part body 2a. By pressing the upper part 20 in the z-direction, the upper part 20 is inserted into the lower part 2, wherein the latching hooks 23 latch in the openings provided with undercuts 5b in the front wall 4 and top wall 3 due to the recesses in the x direction , Im in Fig. 4 shown assembled state of the terminal 1, the guide blades 22 and latching hooks 23 are completely in the guide grooves 5 and hook guides 5a completely received, wherein the lower edges (here on both longitudinal sides in the y direction) of the upper body 20a rest on the upper side of the lower part body 2a. Furthermore, the centering elements 25 are received in the corresponding with them centering 6 of the lower part body 2a, wherein the channel mandrel 28 is disposed in the space between the centering elements 25 of the upper body 20a. The guide cheeks 27 facilitate with their bevelled upper ends of the insertion and centering. The upper part 20 is inserted immovably in this way in the lower part 2. Displacements in the y- and / or x-direction are limited by the guide grooves 5, pulling out in the z-direction is prevented by the latched in the openings with undercuts 5 b locking elements 24 of the latching hook 23 of the upper part 2.

A pulling out of the upper part 20 from the lower part 2 is possible if both sides of the locking elements 24 of the latching hooks 23 are each pressed in the x-direction by means of a tool in the lower part body 2a to release their latching.

The terminal block 1 can be used in this embodiment with its lower part 2 and its upper part 20 as a double terminal device. It is also possible for the conducting element 13 of the lower part 2 to be used as potential earth connection (PE), e.g. via a connecting bracket, not shown, with the support rail 38, is usable.

Furthermore, it is possible to electrically connect the line element 13 of the lower part 2 with the line element 13 'of the upper part 20 via a vertical connector 30.

Fig. 5 shows a schematic perspective side view of the assembled terminal block 1 according to the invention Fig. 3 before using a vertical connector 30 and Fig. 6 adjusts the terminal block 1 Fig. 5 with inserted vertical connector 30.

The vertical connector 30 has a holder 31 with guide sections 32 and a line section 33 fixed therein. The holder 31 is made of an insulating material with top-mounted corrugations for better handling, wherein the line section 33 here consists of two electrically conductive metal strips, which are designed, for example, as a stamped and bent part, starting from the holder 31 in the z-direction downwards - first form a straight section. This is followed by an upper part connection 34, which consists in the fact that the extension of the conductor section 33 here in the y-direction is enlarged by a bulge. Next in the z-direction, a straight again extending connecting portion 35 is arranged, which terminates in a downwardly tapered end portion 36. Before this end portion of the connecting portion 35 is extended in a certain range here in the x-direction, for example, also notched, which is out 10 and 11 is apparent.

For insertion of the vertical connector 30 of the vertical channel 7, 7 'of the upper body 20a is inserted centered in the lower body 2a, that the vertical channel 7' of the upper body 20a is aligned with the vertical channel 7 of the lower body 2a. These serve u.a. also the centering elements 25 and the corresponding with them centering 6th

The vertical connector 30 is now inserted with the end portion 36 from above into the upper opening of the vertical channel 7 'of the upper body 20a in the transverse groove 37 between the transverse walls 9'. The end portion 36 and the adjoining portions 35, 34 and 33 of the vertical connector 30 are first guided through the vertical channel 7 'of the upper body 20a so that the end portion 36 with its tip slightly through the contact opening 15' of the central portion 14 'of the conduit element Thread 13 'of the upper part 20 and penetrates into the upper opening of the vertical channel 7 of the lower part body 2 a between the guide cheeks 27. Then, the further insertion of the vertical connector 30 of the end portion 36 and the subsequent section 35 in the channel mandrel 28 of the lower body 2a continue, whereby the end portion 36 in turn can easily thread into the contact opening 15 of the central portion 14 of the conduit member 13 of the lower part 2 and finally in an end position of the vertical connector 30 in the connector receptacle 29 below the lower Contact opening 15 is received in the lower part body 2a. In this case, the guide portion 32 of the holder 31 of the vertical connector 30 is guided in the transverse groove 37 guided between the transverse walls 9 'on the upper side of the upper body 20a.

Fig. 7 illustrates the terminal 1 with inserted vertical connector 30 after Fig. 6 seen from the opposite side, ie now the top walls 3, 3 'in the foreground. Here is also the opening with an undercut 5b to see in the top wall 3, in which the not visible in the previous figures, other locking element 24 is locked.

Furthermore, it is off Fig. 7 it can be seen that the channel cover wall 26 in extension of the top wall 3 'of the upper body 20a down in the z-direction has a trapezoidal shape and in a Kanaldeckwandaufnahme 26 a, which is formed in the top wall 3 of the lower part body 2a is added.

Fig. 8 shows a perspective cross-sectional view of the terminal 1 after Fig. 3 in the region of the vertical channel 7, 7 '. Fig. 9 displays an enlarged view of area IX Fig. 8 there. Fig. 10 shows a perspective cross-sectional view of the terminal after Fig. 6 with inserted vertical connector 30; and finally shows Fig. 11 an enlarged view of the area XI Fig. 10 ,

In Fig. 8 the upper part 20 is shown in the insertion process in the lower part 2, wherein a section in the xz plane through the vertical channel 7, 7 'is shown. The vertical channel 7 is defined in an upper portion of the top wall 3 'and the front wall 4' of the upper body 20 a and has a rectangular cross-section. The upper opening of the vertical channel 7 and the inner sides of the transverse walls 9 ', which bound the opening at its upper side in the y-direction left and right, are adapted corresponding to the guide portion 32 of the vertical connector 30, as well as in Fig. 10 you can see.

The channel cover wall 26 forms a protection and a cover of an exposed portion of the vertical channel 7 'and the conductive portion of the vertical connector 30 inserted therein.

The vertical channel 7 of the lower part body 2a is defined by the top wall 3 and the front wall 4, wherein the connector receptacle 29 is additionally limited in the z direction by a transverse wall 9.

In Fig. 9 are the contact openings 15, 15 'clearly visible. Fig. 10 shows the inserted vertical connector 30 in its end position. In this case, the holder 31 is received with the guide portion 32 in the upper opening of the vertical channel 7 'of the upper body 20a and is fixed in the z-direction with a shoulder to a stop of the opening.

The line section 33 is received in the vertical channel 7 'of the upper body 20a. The top connection 34 with bulges in the y-direction is defined in the contact opening 15 'of the central portion 14' of the upper conduit member 13 'due to their spring characteristics and thus forms an electrically conductive contact between the conduit portion 33, the connecting portion 35 and the conduit member 13' of the upper part 20. Of course, the upper part 34 may be executed differently, for example with notches with cutting sections.

The connecting portion 35 of the vertical connector 30 is received in the vertical channel 7 of the lower body 2a, wherein the lower part connection 35a of the connecting portion 35 in the contact opening 15 of the central portion 14 of the conduit member 13 of the lower part 2 is determined due to their bulges in the x direction. This can also be done in other ways, e.g. by means of notches with cutting sections. In this way, an electrically conductive connection between the line elements 13 and 13 'via the connecting portion 35 of the vertical connector 30 is made.

Due to the bulged in different directions connections 34 and 35a and correspondingly adapted contact openings 15, 15 ', it is possible that the lower part connection 35a through the contact opening 15' of the upper part 20 is easy to carry out. In this case, this contact opening 15 'is then widened correspondingly in the x direction.

Another embodiment, not shown but based on the FIGS. 4 to 6 is easy to imagine, is that the more than two levels of terminals from "top 20 and the lower part 2" are formed. In such a so-called double-decker clamp, the vertical connector 30 can be used in the same or similar manner. It could be provided over three levels extending vertical connector or there would be more vertical connectors that connect two of the levels conductive.

2. 2) Durchgangsklemme Oberteil 20 und PE-Klemme Unterteil 2
3. 3) Verbindung über Vertikalverbinder 30 von Oberteil 20 und Unterteil 2
4. 4) Verbindung über Vertikalverbinder 30 von Oberteil 20 und Unterteil 2 als gemeinsame PE-Klemme.

With the terminal block 1 with upper part 20 and lower part 2 four versions are possible:

1. 1) Through terminal upper part 20 and through terminal lower part 2
2. 2) Through terminal upper part 20 and PE terminal lower part 2
3. 3) connection via vertical connector 30 of the upper part 20 and lower part 2
4. 4) connection via vertical connector 30 of the upper part 20 and lower part 2 as a common PE terminal.

Terminal block 1 is also referred to as a "piggyback" terminal.

The invention is not limited to the embodiment explained above. It is modifiable within the scope of the appended claims.

Thus, the lower part 2 and the upper part 20 of the terminal 1 also unequal terminal sides A, A 'with plug receptacles 8, 8' have. All combinations are conceivable.

The lower part 2 can also be found separately without upper part 20 use.

A plurality of vertical connectors 30 may be used, which are arranged parallel to one another in the y-direction, the middle sections 14, 14 'of the line elements 13, 13' having a corresponding number of contact openings 15, 15 '.

The vertical connector 30 may also include an insulated lead portion 33 which is formed so that the lead portions 13, 13 'are not connected but are connected to lead out lines, eg for measurement purposes or for a reporting element (lamp). For this purpose, it is also possible to provide two vertical connectors 30, one of which makes contact with the line element 13 and another with the other line element 13 '.

The transverse grooves 37 may be provided for receiving cross connectors, which in the x direction via two or more juxtaposed terminal blocks 1 connect either to one conductor element 13, the other conductor element 13 'or both.

For example, with two vertical connectors 30 which contact the line elements 13, 13 'separately, so many variations can be made to connections with adjacent terminal blocks.
