4 is an exploded view of a terminal block of the type of Fig. 1st

For simplicity, in Fig. 1, a Cartesian coordinate system X / Z is drawn net, wherein the direction perpendicular to the sheet plane is referred to as the "Y-direction". The conductor insertion direction is hereinafter referred to as the "X direction". 1 shows a housing 1, which is designed here as a terminal housing. In the housing one or more - here two - connection devices 2 are arranged to connect to a respective conductor end 3. It is shown in Fig. 1, only one of the water conductor ends 3. Conductor ends 3 can be (preferably stripped-down) individual cores or multiple or stranded conductors or, for example, crimped conductor ends made of a highly electrically conductive material, such as copper.

The housing 1 is made of electrically insulating material, in particular from egg NEM non-conductive plastic. The housing 1 is constructed here like a disk and is preferably arranged vertically aligned to the conductor insertion in the Y direction. The terms right, left, up and down refer to the representation of the figures and change accordingly in a movement of the housing 1 in the room.

The housing 1 may have a mounting foot 1 1. Here is this set to, in particular snapping, on a (not shown, for example, in cross-hat shaped) support rail formed. The housing 1 also has an upper side 12 (this is the side facing away from the mounting foot 1 1) and two Einsteckseiten 13, 14. In a (imaginary) coordinate system, the direction perpendicular to the image plane as Y-direction (in this direction extends the mounting rail), the direction perpendicular to the support rail (in Fig. 1, the direction ver upwardly) as the Z direction and the direction perpendicular thereto (in Fig. 1 to the left) as the X direction. The two conductor ends 3 are movable in and against the X direction. The conductor insertion direction of the right conductor end 3 into the right-to-circuit device 2 is thus the X-direction and the conductor insertion of the left (not shown here) conductor end in the left connection device 2 is the -X- direction.

The connection devices 2 may be of the same design or have a symmetry relative to one another, such a mirror symmetry to the imaginary plane zz 'perpendicular to the plane of the drawing. As a result, two conductor ends 3 are good and easy to insert from opposite sides in the housing 1 and contacted in this of the respective connection device 2. This is for example advantageous haft has been implemented in the embodiment of FIGS. 1-3. Furthermore, as shown, two or even more of the connection devices can be arranged in a housing, thus also next to one another (eg in the case of a multi-part housing 1).

The connection devices 2 each have a clamping spring arrangement 4 and a rotary lever arrangement 5. In addition, they each have a busbar section 6, against which the respective conductor end can be pressed or pushed by means of the clamping spring arrangement. The clamping spring arrangement 4 acts in each case in the manner of a compression spring.

According to Fig. 1, the busbar sections 6 are integrally formed with each other, so that the two connection devices 2 by a one-piece power rail here are conductively connected. In this way, a feed-through terminal without an electrical function module between the two connection devices is realized. It would also be conceivable to form the two busbar sections 6 as separate busbars, which are connected to each other directly or via at least one electrical cal or electronic component conductive each other.

The busbar sections 6 preferably have a V- or U-shape in cross-section (see also FIG. 1 f). The rear extension direction of the busbar sections 6 is perpendicular to this V or U-section in the X direction. In the con nection devices 2, the respective conductor end 3 is in each case parallel to this Lapel extension direction (+ X, -X) introduced. The housing 1 has for this purpose in Verlän delay of the respective busbar section 6 each have an insertion opening 17 for the conductor. The V or U-shape may extend over the entire length of the busbar arrangement in the main direction of extension or over part of the length.

The clamping spring assembly 4 is designed such that it can be swung out to insert the jewei time conductor end 3 of the busbar section 6, so that a conductor end 3 section through the insertion 17 in the respective busbars 6 is inserted. For contacting the conductor, the clamping spring arrangement 4 as a whole is moved in the direction and partly into the conductor rail section 6. pivots, wherein the conductor end 3 is contacted. The clamping spring assembly 4 takes in the contact position, finally, a fixed position and presses the Lei terende 3 against the respective busbar section 6 of electrically good conduct the material, so that at least one contact point is formed, through which an electric current can flow.

The clamping spring assembly 4 consists of one or more clamping springs 41, 42 (see also Fig. 2a and 3a), which are designed as leaf springs. According to Figure 1, two leaf springs are provided which serve to generate a sufficient contact force. These leaf springs each have at least one clamping leg 410, 420 and at least one actuating limb 41 1, 421. The at least one clamping leg 410, 420 and the at least one actuating leg 41 1, 421 are aligned at an angle, preferably at an acute angle at an angle between 5 ° and 85 °, to each other. They are also preferably connected to each other via a bending region 412, 422 or a kind of radius. The bending region 412, 422 preferably rests against a spring carrier 45. In Fig. 2 and 3, the conductor end is not shown, which better illustrates the rotational movement of the clamping spring assembly 4, which is otherwise influenced by the action of the clamping leg 3 on the conductor end 3. In addition, there is another leaf spring 43 which is a return spring. It is preferably also preassembled on the spring carrier 45, is supported on this and the clamping springs and can be stretched when moving into the contact position to reset the clamping springs 41, 42 when loosening the clamping position or after loosening the same.

The spring carrier 45 may be formed integrally with the housing 1 or as a separate part to the housing. If it is formed separately from the housing 1, it is advantageous if the clamping spring assembly 4 is preassembled on the spring carrier 45 and then if the preassembled unit can be inserted separately into the housing 1 and fastened there, for example non-positively and / or positively, in particular by clamping and / or resting. The spring carrier 45 can also be arranged to be pivotable in the housing. He can then even - if the actuating arm is rotatably mounted on him - take over the function of this actuating arm 410 in whole or in part. This function is shown in FIG. 3. It then forms part of the clamping spring arrangement 4 in the sense of the claims. The spring carrier 45 can also be preassembled on the busbar, preferably in each case in slots 62 of the busbar sections. 6

The clamping springs 41, 42 of the leaf spring assembly are preferably inserted into one another ge "stack-like" arranged. This means that their bending areas 412, 422 lie inside one another and have exactly or essentially the same axis of rotation D1 or D1 '. The support contour in this case has a rounded pin portion 451, around which the clamping springs 41, 42 Kings in their bending areas 41 1, 412 turn NEN. The spring carrier 45 serves in the region in which the bending portion 412, 422 abuts against it, bolt-like as a pivot bearing for the clamping spring assembly or for the one or more individual springs or clamping springs of Klemmfederan Regulation. 4

Preferably, the actuating legs 41 1, 421 and / or the clamping legs 410, 420 of the leaf springs 41, 42 have different lengths. Are the actuating leg 41 1, 421 different lengths, this allows in a simple way conductor ends 3 various diameters very good to contact each good suitable positions to animals. It is also conceivable to contact a single conductor end 3 with two or more Blattfe countries at different locations.

The clamping spring assembly 4 is preferably oriented such that the Biegebe rich 412, 422 of the respective Leitereinführöffnung 17 is closest, so that the clamping leg 410, 420, starting from the bending region 412, 422 of the Leitereinführöffnung 17 extends away. The respective clamping leg 410, 420 and the respective actuating leg 41 1, 421 are thus preferably at an acute angle to the conductor insertion direction (X direction).

The axes of rotation D1 of the clamping spring assembly (s) 4 and sections of the clamping spring assembly 4 is / are in the region of the support contour or the support contour lies in the Z direction - ie perpendicular to the mounting bracket or the support rail - upper half of the conductor end to be contacted 3 and above the respective busbar nenabschnittes 6. In the Z direction above the clamping spring assembly 4, the respective rotary lever assembly 5 is further arranged, which has a rotation axis D2. The The axis of rotation D2 lies in the Z direction above the axis of rotation D1 of the Klemmfederano ring.

Overall, an arrangement is created such that in the housing 1 at each connection device 2, the busbar assembly 6 is arranged below and is directed with its open side of the V or U-shaped cross-section to the respective Klemmfe deranordnung 4, so that the one or more clamping legs 410, 420 can be pivoted into the busbar arrangement / are. In addition, the axis of rotation D2 of the rotary lever assembly 5 is formed above the clamping spring assembly 4 and ordered. The directions of rotation DR of the rotary lever assembly 5 and DR of the clamping spring assembly 4 are in the same direction or rectified. Thus, in the left-hand connection device in FIG. 1, they respectively rotate in the clockwise direction for contacting and in the right-hand connection device 2 in FIG. 1 in each case for contacting in the counterclockwise direction. To release, they are each rotated in the opposite direction. The se advantageous functionality is explained in more detail below.

With the rotary lever assembly 5, the clamping spring assembly 4 from an open position (Fig. 1 a) (over several intermediate steps of Fig. 1 b to 1 d, Fig. 2a to 2e, Fig. 3a to 3e) to a contact position (Fig e, 2e, 3d) are pivoted. The rotary lever assembly 5 has an eccentric shape. The Drehhebela arrangement 5 has a preferably disc-like rotary lever element 50 which is rotatably mounted in or on a preferably central portion 500 in the housing 1 and has the axis of rotation D2. This can be realized in different ways. In example, the rotary lever element 50 can be placed on a pin in the housing 1 or be penetrated by this and / or it can in a rotary recording contour 15 of the housing 1 - a recording - be used, which surrounds it from sections on the outer circumference anyway.

The rotary lever element 50 has an actuating portion 501, the preference, from outside the housing 1, in particular at an opening 16 on the upper side 12 of the housing 1 - is accessible. The actuating portion 501 may be formed, for example, as a radially projecting from the central portion 500 approach or as an opening in the region 500, which allows attachment of a tool, in particular a screwdriver or the like. He can too in and / or against the direction of rotation in conjunction with an opening 1 6 of the Ge housing, from which it protrudes, serve as a stop for the rotation angle limit (see in each case Fig. 2a).

The rotary lever element 50 further has an eccentric portion 502. The Exzen terabschnitt 502 is here designed as a kind of arm, which extends eccentrically, here substantially tangentially to the central portion 500 radially outward.

The eccentric portion 502 has on its side facing the clamping spring arrangement 4 th page a kind of control cam 503 on which the one or more actuating legs 41 1, 412 of the clamping springs 41, 42 can be brought to bear.

The eccentric 502 can engage with a projection or a pin 504 or the like inserted into it in a backdrop, in particular an arcuate slot 18, the housing 1, which ensures a particularly safe and uniform Öffnungsbe movement.

In the fully open state, the eccentric portion 502 on the Actuate supply limbs 41 1 abut. However, this is not absolutely necessary (FIG. 2a). It is also conceivable - as shown in Fig. 1 a - that it is in the full open position slightly spaced from the clamping spring assembly 4.

The clamping spring assembly 4 can - be held in the open position of Fig. 2, for example, with an auxiliary spring (not shown here) or be moved with the Leiteren de 3 in this, when the rotary lever assembly 5 is rotated in its opening posi tion, in which the eccentric 502 upwards (from the power rail section 6 away) is rotated.

In the position of Fig. 1 a are the rotary lever assembly 5 insofar as the clamping spring arrangement 4 free, so that these by a tool or the conductor in a direction of rotation "-DR" - in Fig. 2a or 3a to the left or in Fig. 1st a at the right to closing device to the right - can be pivoted. In this way, in the corresponding - in Fig. 1a the right or in Fig. 2a, the left-connection device, a conductor end 3 are introduced. To establish the contact position, the rotary lever assembly 5 is now rotated in a direction of rotation "DR" opposite to the direction of rotation "-DR", so that the ex-centric portion 502 with the control cam 503 on the clamping spring assembly 4 for on comes (Fig. 2b). In a further rotation in the direction of rotation DR (Fig. 1 d, 1 d, 2b, c, 3b, c) of the eccentric 501 acts like a rotary lever - here as an ever-longer rotating lever - on the one or more actuating legs 41 1, 412 a. Here it acts on the outer actuating leg 41 1 and pushes it in -Z- direction downwards (in this case in the direction of the mounting rail down). As a result, the entire clamping spring assembly 4 is rotated in a direction of rotation DR gleichgerich ended rotational direction DR. This presses the clamping leg or legs 410 more and more strongly radially against the conductor end 3 and presses it against the associated busbar section 6.

It is particularly advantageous that the forces required for actuation are relatively low due to the rectified directions of rotation.

This is particularly clear from a comparison of Figures 1 b to 1 f - right side of the illustrated terminal - out. For these figures show that the point or the area at which the eccentric 501 each touches the Klemmfederan order 4, from image to image with the increasing closures or Andrü bridges of the clamping spring assembly 4 to the head radially on the Exzenterab cut 501st migrates to the outside. Here, this is done until the pin 504 is reached in the ra dial outermost region of the eccentric portion 501.

In Fig. 1, the end contact position is reached in Fig.1 f. In this position, the actuating leg 41 1, 421 and / or the rotary lever assembly 5 may additionally be positively and / or non-positively fixed, for example on the busbar section 6 or on another element, so that a particularly stable Endkontaktstellung is realized, which is also under higher loads does not solve.

The advantages described in the preceding paragraphs have not or not sufficiently recognized in the prior art, since there are other, less important points have been made in the design implementation in the center. From this, the invention turns away and provides instead the safe reach a uniform Beschaltungsbewegung and Entschaltungsbewegung and the achievement of a low loading and Entschaltkraft and the achievement of a high con tact force in the final contact position in the center.

Hereinafter, further constructive variants are described, with which the inven tion can be additionally optimized.

Thus, the one or more actuating legs 41 1, 421 ge at their free ends be formed kröpft to a good sliding of the control cam on the or the actuator should tion legs 41 1, 421 ensure.

Upon reaching the Endkontaktstellung press or the clamping legs 410, 420 on the conductor end (Fig. 1 d, e), until preferably the clamping spring assembly 4 and / or the rotary lever assembly 5 positively and / or non-positively fixed to an abutment is / are.

It is preferably provided that on the eccentric portion 502, a locking means, for example, the aforementioned pin 504, is formed, which is movable in the link 18 in a fixing position. Particularly preferably, this fixing position is formed in the busbar. It may be advantageous to provide that the coolies se 18 passes in the housing before reaching the detent position in a corresponding backdrop 60 in the respective busbar section 6 and in this en det. In this case, the backdrop 60 in the respective busbar section an Eng point 61 or have an over-center position, in which the pin 504 in He reach the end contact position fixed in position, in particular locked, is. This is especially good in Fig. 1 g can be seen. The backdrop 18 is aligned with the backdrop 60. Just to release the final contact position, it is only necessary to move the pin from the detent position behind the constriction 61 of the link 60 in the busbar with a rotation of the rotary lever assembly 5.

It is particularly advantageous if the fixation of the end contact position takes place permanently securely on the metallic busbar 6 and not in the plastic housing 1. The attachment of a pin 504 to the eccentric portion and the formation of the detent position in the slot 60 of the busbar section 6 provides a particularly simple variant for realizing a fixation of the spring arrangement in the end contact position, which also provide a light and uniform usability when making the contact position and the release thereof results. It is also advantageous, in particular special, that for releasing from the end-contact position no latching hook or the like. Must be solved on the spring assembly from a locking position.

According to Fig. 3 it is provided that the spring carrier 45 is arranged pivotably in the housing 1. He then takes over - since the actuating arm is arranged to rotate on him - the function of this actuating arm 41 1 wholly or partially with. This function is shown in FIG. 3. The eccentric section 502 acts here over part of the rotational movement on the spring carrier 45 or on an arm 452 of the spring carrier and rotates the contact spring. The one or more clamping legs are exposed and still act as a clamping spring legs. The spring carrier 45 also forms part of the clamping spring arrangement 4.

Fig. 4 illustrates in addition with reference to an explosive view the structure of a Rei henklemme on the type of Fig. Good to see the disc-like structure of the housing 1 in anreihbarer design. In addition, it is easy to see here that the disk-like housing 1 can be constructed in several parts. The housing 1 may be composed of two half-shells 101 and 102 in example - as shown. In one or both of the half-shells 101, 102 may be the backdrop out 18 forms, which here at one of its ends in each case with the link 60 in the jewei time busbar section 6 is aligned. The other half-shell is designed here as a back wall.
