Fig. 1 shows various views of a first connection device 1 in a design as a double connection for connecting two conductors.

In this case, this connection device 1 is designed such that the two conductors are individually inserted into the connection device to contact them and so that they are detachable from this connection device again. The connecting device 1 is further designed such that the two connected conductors are conductively connected to each other via the connecting device 1.

The connection device 1 is designed as a so-called connection in direct plug-in technology, that is, conductors can be plugged directly into the connection device 1 without tools.

The connection device 1 has a clamping and contact cage 2 of conductive material, in particular of a highly conductive metal. This clamping and contact cage 2 has in the plan view of Fig. 1c a rectangular shape, preferably even a square basic shape. He also assumes power-conducting function.

In the clamping and contact cage 2, at least one clamping spring 3 is arranged, which serves as a spring element for applying a contact force to a conductor, but could also optionally serve as a contact element when choosing a suitable conductive spring material and possibly also electrically conductive function in the manner of a Busbar could take over, but what is not provided according to the illustrated embodiments.

To Fig. 4 the clamping spring 3 has a V-shape with a base leg 4, which is fixed to the inside of the clamping and contact cage (by stapling or the like.).

The clamping spring 3 further comprises two adjacent conductive contact and / or clamping legs 5, 6, which are each connected via a bend 7, 8 with the base leg 4.

From the side view of Fig. 4a shows that the contour of a clamping spring in push-in technology is realized on the clamping spring 3. The two contact and / or clamping legs 5, 6 are directly next to each other. If a conductor is inserted into the clamping and contact cage 2, he pushes one of the two contact legs 5, 6 to the side when inserted into the respective one of the two clamping point 9 - if this is not already open with an actuating element or the like. Fig. 1c ). In the inserted state, the clamping spring 3 then presses the conductor (s) against the clamping and contact cage 2, so that the conductor is contacted (electrically conductive). By providing the two contact legs 5, 6 two conductors can be contacted side by side in the terminal and contact cage 2 independently. The loading and unloading with the individual conductors can be done independently.

The clamping and contact cage 2 also has on its side facing away from the bends 7, 8 side at least one projection 10 (see also Fig. 11 ) or a plurality of approaches, wherein this approach 10 preferably extends beyond the remaining edge of the clamping and contact cage 2 and is designed as at least one leg, preferably spring leg, a busbar element - a cross-sectionally rectangular busbar or, for example, a conductor piece 12 round cross-section (please refer Fig. 11 ) - Press against a corresponding further element, in particular one or more abutment legs or lugs 19, 20 of the clamping and contact cage.

The projection 10 preferably has a bend 14, via which it is connected to the clamping and contact cage ( Fig. 1-4 ).

The clamping and contact cage 2 is made according to all variants shown in a preferred embodiment - but not mandatory - as a stamped and bent part of a sheet metal blank. This sheet metal blank is preferably made of a sheet of good electrically conductive material, so that the clamping and contact cage itself 2 can take an electrically conductive function.

The clamping and contact cage 2 has a rectangular or square shape in plan view. A flat sheet is bent into this contour. It is advantageous if by means of lateral edges of this sheet metal blanks partition walls 17, 18 are bent, which extend into the interior of the clamping and contact cage 2 and in this conductor connection chambers 44, 45 form, which facilitate the insertion of the conductors into the respective contact point.

The clamping and contact cage can also (see Fig. 7 ) have one or more inwardly projecting webs 11, which serve as opening travel limit stops for the clamping spring 3.

The clamping and contact cage 2 has a conductor insertion side, which serves to introduce the two conductors in the direction X in the clamping points. On the side opposite the conductor insertion side, it preferably has one shoulder or two or more of the lugs 19, 20 which are bent in such a way that they form one or more contact areas for the busbar element in interaction with the previously mentioned lug 10.

Thus, from the material of the clamping and contact cage 2, a further terminal 21 is formed, which serves for the connection of the busbar element 12. The connection device of Fig. 11 has a largely analogous structure.

The embodiments of Fig. 5 to 9 differ from those of Fig. 1 to 4 and 11 in particular with regard to the configuration of the further terminal 21 'for the busbar 12 or the conductor piece.

This further terminal 21 ', which is used to contact the busbar element, is after Fig. 5 to 11 from a projection 10 'on the clamping spring and at least one, in particular two, lugs 19, 20 formed on the clamping and contact cage 2.

This embodiment is particularly advantageous because in this case the clamping spring 3 made of spring material optimizes the contact force on the further connection 21 'and presses the conductor or conductors against the projection 19 or 20 on the clamping and contact cage 2.

The current-conducting function can be taken over in this case by the clamping and contact cage 2 (and / or by the clamping spring 3).

To Fig. 4 and 5 are the lugs 19, 20 further configured partially overlapping each other and each have aligned, a the busbar section adapted Kontaktierungskontur. The contacting of the conductor rail element takes place in two levels next to each other.

The arranged on the clamping spring 3 approach 10 'has a bend, which is after Fig. 8 first away from the base leg into the interior of the clamping and contact cage 2 and then over a turning area 15 almost in the manner of an S back to the base leg and preferably protrudes from the clamping and contact cage 2.

The clamping and contact cage 2 is after Fig. 7 divided by inwardly projecting partitions 17, 18 even more in each case partially separate connection chambers 44, 45 ( Fig. 7 and 17 ). Although the individual conductors are then not in circumferentially closed individual chambers but in defined sub-chambers of the interior of the clamping cage. 2

To Fig. 1 to 4 contact the two lugs 19, 20, the busbar element in contrast in a plane.

The clamping and contact cage 2 realized after Fig. 1 to 4 and 11 a triple function.

He acts in the contacting of two conductors as an abutment for the clamping legs with the conductors and acts with the lugs 10, 19, 20 in the contacting of a busbar element in a device in which it can be a terminal block, in particular a jumper. It also serves as a busbar or conductive connecting element between the contact point 9 and the busbar element 12.

To Fig. 5 to 8 in contrast, the connection is advantageously formed from the clamping spring 3 and the clamping and contact cage 2.

Fig. 9 shows such a jumper 24 having an insulating housing 22, which locking means 23 for latching on a cross-hat-shaped support rail (not shown).

The insulating material housing 22 has a plurality of connection devices 1 designed as double-conductor connections, which, in the manner of the connection devices, have the Fig. 1 to 4 or according to the type of connections Fig. 5 to 8 or by type Fig. 11 are configured, and as so-called connections in direct plug-in technology (push-in), which are thus designed to be particularly compact.

For the connection devices 1 insertion openings 25 are formed in the insulating 2.

The jumper 1 is preferably formed symmetrically to the mid-perpendicular M on the support rail.

It has a substantially triangular or trapezoidal basic shape with one on both sides of the mid perpendicular M perpendicular to this extending base side 26 and two inclined sides 27, 28.

The base side 26 and the oblique sides 27, 28 form the sides of an isosceles triangle, in the corner region still short side pieces 29 may be arranged.

The two, preferably stepped, inclined sides 27, 28 lie on the mid-perpendicular M on the mounting rail. They are each aligned at an acute angle to the mid-perpendicular M and to the base side 26. The angle α between the base side 26 and the inclined sides 27, 28 is preferably between 20 ° and 70 °.

In the two inclined sides 26, 27, the terminals 1 are distributed. One of the double connections in each case lies in a plane above the mounting rail. These two terminals of a double connection are each connected to one another via one of the conductor rail elements 12, which may also have a round cross-section and thus may also be formed as conductor pieces, which is inexpensive.

It is thus possible to accommodate many of the conductor terminals 4 on the sloping sides.

Preferably, in each case the two of the mounting rail respectively equidistant spaced conductor terminals 4 on the inclined sides 26, 27 connected in pairs with the busbar elements together, so that a feed-through terminal with a plurality of busbar levels E1, E2, E3, ... is formed. These busbar levels E1, E2, E3, ... are preferably galvanically separated from each other.

However, it is possible to connect individual busbar levels E1, E2, E3 ... by means of connectors.

The clamping and contact cages 2 can be locked on / in the insulating housing. The double connections can be assigned to one or more actuators (pushers) in order to be able to open the clamping points by pressure on these pushers in order to remove conductors or to be able to introduce them more easily. But it is also conceivable to open the clamping legs with a tool such as a screwdriver.

Below is closer to the embodiment of 11 to 17 considered.

The connection device of Fig. 11 has a largely analogous structure to the embodiments of the Fig. 1 to 4 on.

The function of the further connection 21, which is integrated in the clamping and contact cage 3, for a conductor element can be seen particularly well. The further connection is formed as a spring connection, ie, the projection 10 and a bow-like further approach 31 act in interaction as the two spring legs of the spring terminal 21 for the conductor piece 12, between which the conductor piece 12 is clamped contacting ( Fig. 11 . 12 ). The clamping and contact cage 2 acts like a busbar.

The projection 31 is stirrup-like punched out of the material of the clamping and contact cage, i. he is connected in two places with the rest of the clamping and contact cage.

The projection 10 and the projection 31 preferably have geometry adapted to the geometry of the conductor (recesses 32, 33) for receiving peripheral portions of the conductor piece 12 (FIG. Fig. 12 . 13 . 14 ).

These contact zones 34, 35 forming recesses 32, 33 of the lugs 10, 31 may be configured such that they are aligned in the contacting state so obliquely to the conductor piece 12 that they cut into this point or line-like or that they scored this, so that a good electrical contact is realized.

Fig. 15 illustrates that by means of a web or two of the clamping and contact cage inwardly bent to the clamping spring webs stops 36, 37 are formed for limiting the Einschiebebewegung for the conductors.

It is also conceivable to integrate webs as limit stops 38 for limiting the insertion movement for the actuating pushbuttons into the clamping and contact cage ( Fig. 17c ).

The conductor piece 12 can be inserted from both sides into the contact region of the terminal 21, ie there is a connectability of two sides, so that it is not necessary to create different variants for a connectability of two sides (see Fig. 14a where this is illustrated with two arrows P1 and P2).

The clamping spring 3 is preferably designed as a double spring, but it is also conceivable to place two separate clamping springs next to one another in the clamping and contact cage 2.

The separate Beschaltbarkeit is advantageous in any case by a certain geometric independence of the individual chambers 44, 45 ( Fig. 7 . Fig. 17a ) from each other. These also provide mismatch protection, protect against splicing or mis-routing of the strands, and allow the placement of two independent pushbuttons 42 (FIG. Fig. 17c ).

The clamping spring (s) can be riveted or welded to the clamping and contact cage (zone 39, Fig. 16a ). By converted edges 40, 41 on the clamping and contact cage, it is also conceivable to realize a prefixing of the spring as an assembly aid or as a position fixing aid ( Fig. 16b, c ). However, it is also conceivable to fix the spring in other ways, eg subsequently by harpoon-like webs 43 (FIG. Fig. 15 ).

Instead of the spring connection 21, other connections can also be realized as the further connection, for example, soldering legs for soldering on a printed circuit board or a welding zone for connection to a further busbar or printed conductor (see FIG. Fig. 24 - 26 ).

The Fig. 18a-f and 19a-h show various views of a fourth connecting device, a largely to the embodiment of the Fig. 11 has analog structure.

Particularly advantageous in this embodiment, the positioning of the clamping spring 3 in the clamping and contact cage. Second

How from the interaction of Fig. 19 and 18 can be seen, the clamping spring 3 in turn has a base leg 4, which is fixed to an inner side or inner surface of the clamping and contact cage 2.

The base leg 4 is provided in each case with at least one edge recess 46 at its two longitudinal sides ( Fig. 19h ), in which tabs 47 intervene ( Fig. 18a, b ), which are punched out of the material of the clamping and contact cage 3 and are bent by the edge recesses 46 by 180 ° inwards, so that they fix the base leg 4 on the clamping and contact cage. In this way, in particular, an excellent positive and non-positive locking is realized against loosening of the clamping spring 3 against the insertion direction X. Additionally / alternatively, the clamping spring 3 also on the clamping and contact cage in other ways, so by imprinting. Fig. 19 again shows the transition of the base leg into two separately operable clamping legs / contact legs 5, 6.

It can further be seen that the edge regions 48 of the base leg are provided with an embossment, which causes the base leg 4 to lie down in the inner bending regions / corner regions of the clamping and contact cage 2. Such a simple way is effectively avoided that the clamping spring 3 can not create because of internal radii of the clamping and contact cage 2 inside of this.

A further displacement protection can be realized in that lateral webs 49 engage on the clamping spring 2 in slots 50 in the clamping and contact cage 3, in particular such that the webs 49 are supported in the insertion direction X of the conductor in the slot 50 on the clamping and contact cage 3.

Fig. 20 and 21 show a terminal block assembly, as it can be realized by way of example with terminal blocks of a type according to the invention.

As can be seen well, are edge webs 51 with respect to the upper - ie in the mounting position away from an assembly support rail - oblique sides 27, 28, wherein from the inclined sides 27, 28, the actuation push-buttons 42 project, in the Z-direction upwards. This offers the advantage that it is much easier during assembly to detect the transition between mutually adjacent terminal blocks, which minimizes the error rate during Beschaltungsvorgang. Fig. 20 and 21 also illustrate well the compact design of the implemented with push-in contacts in accordance with the invention terminal blocks, especially Christmas tree clamps.

For actuation, the actuation push-buttons 42 serve.

Here, each row terminal in the direction of arrangement twice four rows R1, R2 and perpendicular to the mounting direction four perpendicular columns S1, S2, S3, S4 of the actuating lever provided.

Without the edge webs 51, which run perpendicular to a mounting rail, a relatively large field of actuating levers 42 would result in the risk of an excessive number of faulty circuits during assembly. This danger is significantly reduced by the edge webs 51.

It can be further reduced if, by means of further transverse webs 52 perpendicular to the edge webs 51, preferably between the edge webs 51, the field of actuation push-buttons 42 within each terminal is optically subdivided again.

It is conceivable that the transverse webs 52 have a different height than the edge webs 51. Thus, it may be provided that they are lower in the Z direction (perpendicular to a mounting rail on which the terminal block assembly is mounted) than the lateral edge webs 51st The edge webs 51 are preferably higher in the Z direction than the actuation push-buttons 42, so that the actuation push-buttons 42 are visually recognizable and lockable by the edge webs 51 and the edge webs 51 prevent the actuation push-buttons 42 from being damaged, for example protect during transport. The transverse webs 52, however, are preferably less high than the actuating pushers 42 in the non-depressed state and preferably further dimensioned such that they effectively limit the maximum actuating travel or stroke of the associated actuating pusher 42.

The edge webs 51 are preferably aligned with the main side walls of the insulating housing in the direction of arrangement or form part of these side walls.

On the one hand, the transverse webs 52 increase the security of wiring, but on the other hand, they can be an approach for limiting the movements with a screwdriver form. The edge webs 51 are preferably not only higher but also wider than the transverse webs 52.

Third webs - one or more intermediate webs 53 - can also optically and also functionally separate the actuation push-buttons 42 and the two connections of each double connection. These intermediate webs 53 preferably extend parallel to the edge webs 51 and perpendicular to the transverse webs 52 and also serve primarily to reduce the risk of faulty connections.

Randausnehmungen 54 on the inner sides of the edge webs 51 and / or the intermediate webs 53 again increase the optical separation effect with respect to the actuating handle 42. The edge recesses 54 can also be used advantageously as a receiving area for the edge region of conductor insulation or sleeves or the like., Which significantly Achieving a particularly compact design contributes.

Preferably, the actuating slots 15 of the actuating pushers 42 are aligned perpendicularly or at least at an angle to a mounting rail. In this way, it is effectively prevented in a simple manner that the wrong row of actuating pushbuttons is connected or opened.

The individual terminal blocks can be pre-assembled by means of corresponding positive and / or non-positive means (pins 55, recesses) to form a composite, which can be mounted as a whole pre-assembled on a mounting rail.

Good to see in Fig. 20 and 21 also that Markiererrastaufnahmen 56 are provided in an upper mid-surface area between the two sloping sides of the Christmas tree clamp, which are easily accessible and particularly well visible.

Also clearly visible is the inclined arrangement of the individual columns of the connections on the oblique sides of the terminal block.

Fig. 22 shows various views of another embodiment of a jumper terminal 24 with a metal assembly with connecting devices 1 according to the invention, wherein in Fig. 22c, d in each case a section of the jumper terminal 24 is shown.

Analogous to the embodiments of the jumper terminals 24 of Fig. 9 . 20 and 21 has the jumper 24 of Fig. 22 arranged symmetrically to the mid-perpendicular M latching means 23, in each of which a groove 231 is arranged. By means of the latching means 23, the jumper terminal 24 can be arranged on the mounting rail 57. In each case, a leg 571 of the support rail 57 engages in the groove 231 of a locking means 23 a.

Opposite the jumper 24 of Fig. 9 . 20 and 21 has the jumper 24 of Fig. 22 However, each locking means 23 adjacent to a side stop 58, which prevents overloading of the side stop 58 adjacent latching means 23 when snapping or loosening the jumper 24 of the support rail 57.

Fig. 23a-c shows the arranging and fixing of connecting devices 1 in the jumper 24 of Fig. 22 , In the Fig. 23a the connection devices 1 and the busbar elements 12 are not yet arranged in the insulating housing 22 of the jumper terminal 24, while the connection devices 1 and busbar elements 12 in the Fig. 23b already inserted into the insulating housing 22.

In this case, clearances 111 are provided for the connection devices 11, into which the connection devices 1 can be inserted. In the clearances 111 each have a retaining lug 113 is arranged, on which a connection device 1 can be pushed. For this, the connecting device 1 to the retaining lug 113 in relation on their shape corresponding recesses 114 which engage around the retaining lug 113 in the inserted into the insulating housing 22 state of the connecting device 1.

For the busbar elements 12, however, latching hooks 112 are provided, in which they can be latched.

However, the connection devices 1 in the Fig. 23b each not yet fixed in the franking 111 or on the respective retaining lug 113 and thus still displaceable. Therefore, the connection devices 1 are embossed in the region of the retaining lug 113, z. Example by means of cold embossing or hot stamping, so that the connecting devices 1 each fixed to the retaining lug 113 to which they are deferred and are no longer displaceable.

The Fig. 23c shows the embossed in the insulating housing 22 at embossments 115 connecting devices. 1

Fig. 24 shows in a section of a further embodiment of a jumper 24. Instead of the connection of the connection devices 1 by means of busbar elements 12, however, the connection of the connection devices 1 by means of conductor tracks 121 of a circuit board 59 is provided here. For this purpose, a connection 10 "is provided on the clamping and contact cage 2 of each connecting device 1, which is here tongue-like and is provided for soldering to a soldering point 591 of the printed circuit board 59.

The Fig. 24a 1 shows the jumper terminal 24 with the printed circuit board 59. On the printed circuit board 59, the soldering points 591 are shown, to each of which a lug 10 "of a respective clamping and contact cage 2 of a connecting device 1 is soldered Schematically and by way of example, a conductor track 121 provided in the printed circuit board 59 is indicated by a dashed line.

In order to enable the most flexible possible configuration of a jumper terminal 24, the projection 10 "has a connection angle β which is variable with respect to the insertion direction X.

In contrast to the shape of the approach 10 "of the connection devices 1 of Fig. 24 is the approach of the connection device of Fig. 25a-c not tongue-shaped but u-shaped.
