Description

Technical Field

[0001] The present invention relates to a connection arrangement for connecting electrical conductors, comprising: a busbar; a clamping spring, by means of which the conductor to be connected is clamped against the busbar in a clamping position of the clamping spring; and an actuating element, by means of which the clamping spring can be moved from the clamping position into an open position. The present invention also relates to a terminal having at least one connection arrangement constructed in this manner. The present invention also relates to an electronic device. Background Art

[0002] This type of connection arrangement typically features a clamping spring designed as a leg spring with a retaining foot and a clamping foot. A conductor inserted into the connection arrangement can be clamped against the busbar by means of the clamping spring's clamping foot. In particular, when clamping a flexible conductor, the clamping spring must be moved to an open position and then actuated using an actuating element before the conductor is inserted. This allows the clamping spring or the clamping foot to be deflected away from the busbar in order to insert the conductor into the intermediate space between the busbar and the clamping spring. Only when the conductor is rigid and therefore stable can it exert sufficient force on the clamping spring or its clamping foot to deflect the clamping foot away from the busbar without the user having to actuate the actuating element. For flexible conductors, the user must first actuate the actuating element to deflect the clamping spring away from the busbar in order to insert the flexible conductor. To clamp the inserted conductor, the user must manually actuate the actuating element again to move the clamping spring from the open position to the clamped position. The manipulation of the manipulation element by the user makes the installation or connection of the conductor more difficult, since the operation is cumbersome and thus time-consuming. Summary of the Invention

[0003] It is therefore an object of the present invention to provide a connection arrangement, a connection terminal and an electronic device in which the connection of, in particular, flexible conductors can be simplified.

[0004] The solution of the present invention for achieving the above-mentioned object is characterized by the independent claim. Preferred embodiments and advantageous improvements of the present invention are described in the dependent claims.

[0005] The wiring arrangement of the present invention is characterized in that a retaining element is provided, which engages with an operating element in the open position to hold the operating element in place, wherein the retaining element has a pressing surface, wherein in order to move the clamping spring from the open position into the clamping position, the pressing surface can be manipulated by the conductor to be connected, and the retaining element can be disengaged from the operating element by manipulating the pressing surface.

[0006] The connection arrangement according to the present invention allows flexible conductors to be connected and clamped against a busbar even without manual actuation of an actuating element. The clamping spring is preferably designed as a leg spring having a retaining foot and a clamping foot that can be pivoted relative to the retaining foot. The pivoting movement of the clamping foot allows the clamping foot to be moved into an open position and a clamped position. In the open position, the clamping foot is spaced apart from the busbar, allowing the conductor to be connected to be inserted into or removed from the intermediate space formed between the busbar and the clamping foot. In the clamped position, the clamping foot can rest against the busbar or the conductor to be connected, thereby clamping the conductor against the busbar. The connection arrangement includes a retaining element that, in the open position of the clamping spring, engages with the actuating element in such a manner that the actuating element is held in the open position without additional manual actuation. This also allows the clamping spring or its clamping foot to be held in the open position by the actuating element, so that, in particular, a flexible conductor can be inserted into the intermediate space formed between the busbar and the clamping spring. In this way, the operating element engages with the retaining element in the open position. The retaining element has a pressing surface that is aligned with the conductor insertion area of ​​the wiring arrangement and is arranged in an extension of the conductor insertion opening of the wiring arrangement, so that the conductor presses against the pressing surface of the retaining element during insertion into the wiring arrangement. By applying pressure to the pressing surface via the conductor, the retaining element can be caused to deflect or tilt in the direction of conductor insertion, thereby deflecting or tilting the retaining element away from the operating element in the direction of conductor insertion. The deflecting movement of the retaining element disengages the retaining element from the operating element and, in turn, separates from the operating element, allowing the operating element and the clamping spring to move from the open position to the clamped position without manual assistance. This unique mechanism makes connecting a flexible conductor particularly simple, relying solely on the insertion movement of the conductor, without requiring the user to manipulate other elements of the wiring arrangement, such as the operating element, to release the clamping spring and move it from the open position to the clamped position. This simplifies operation of the wiring arrangement and saves time when connecting the conductors. In order to release the conductor to be connected from the clamped position, the clamping legs of the clamping spring can be pivoted away from the busbar again by means of an actuating element until the open position is reached, and the actuating element engages with a retaining element to retain the actuating element and, via the actuating element, the clamping spring in this open position. The retaining element is preferably an element or component that is designed independently of the clamping spring and the busbar and can be arranged in a conductor connection cavity of the wiring arrangement.

[0007] Preferably, the actuating element can be guided in a direction of movement, transverse to the direction of actuation of the conductor to be connected against the pressure surface of the retaining element, in order to move the clamping spring into the clamping position and the open position. Preferably, the connection arrangement is designed such that the actuation direction or direction of movement of the actuating element is transverse or perpendicular to the insertion direction of the conductor into the connection arrangement. Therefore, the passage formed in the housing of the connection arrangement, through which the actuating element can pass, is preferably designed transverse or perpendicular to the conductor insertion opening formed in this housing. This allows the conductor to be inserted through the side of the housing that is not provided with the actuating element, thereby preventing accidental actuation of the actuating element during the connection process and, therefore, during the insertion of the conductor into the housing. The actuating direction of the actuating element is preferably designed to be purely translational, so that the actuating element can be moved along its longitudinal axis.

[0008] If the direction of movement of the actuating element is designed in a manner relative to the direction of actuation of the pressure surface by the conductor to be connected, the pressure surface of the retaining element is preferably arranged behind the actuating element in the actuating direction. To actuate the pressure surface, the conductor to be connected must be inserted to a certain extent, so that the conductor must be inserted past the actuating element into the wiring arrangement. This ensures that the pressure surface cannot be unintentionally actuated if the conductor is not yet sufficiently inserted into the wiring arrangement, and thus the actuating element and the clamping spring cannot be unintentionally disengaged from the open position. This arrangement of the retaining element ensures that the actuating element and the clamping spring are only moved from the open position into the clamping position when the conductor is sufficiently inserted and is in the desired connection position between the clamping spring or its clamping legs and the busbar.

[0009] To allow the conductor to be connected to pass past the operating element, the operating element may include a free space for the conductor to be connected to pass through the pressing surface of the retaining element. The free space may be formed in the form of a recess in the operating element. The free space formed in the operating element is aligned with the pressing surface of the retaining element in the operating direction of the conductor.

[0010] The clamping spring can have a clamping foot with a clamping tongue and at least one side tongue arranged to the side of the clamping tongue. A clamping edge for clamping the conductor against the busbar can be formed at one free end of the clamping tongue, and an actuating element can interact with the at least one side tongue to actuate the clamping spring. This allows the clamping foot to be actuated by means of the actuating element via the side tongues of the clamping foot, which are provided in addition to the clamping tongues of the clamping foot forming the clamping edge. This allows the function of actuating the clamping foot by means of the actuating element to be separated from the function of clamping the conductor to be connected by means of the clamping tongues of the clamping foot. The side tongues are preferably parallel to the clamping tongues. The side tongues preferably form the outer edge of the clamping foot. A free space or gap is preferably formed between the side tongue and the clamping tongue, so that the side tongue is preferably constructed in a manner spaced a certain distance from the clamping tongue, wherein at a free end of the side tongue, this side tongue is preferably integrally joined to the clamping tongue.

[0011] The clamping tongue is preferably designed relative to the at least one side tongue in such a way that it can extend beyond the at least one side tongue in the longitudinal direction of the clamping foot. As a result, the actuating surface of the actuating element formed by the side tongues on the clamping foot can be set back relative to the clamping edge of the clamping foot toward the bent joint of the clamping spring, which connects the clamping foot to the retaining foot.

[0012] The actuating element preferably has at least one actuating section, by means of which the clamping foot can be actuated. The actuating section preferably interacts with the at least one lateral tongue of the clamping foot. The actuating section thus preferably forms the outer side or outer wall of the actuating element, which can simultaneously form a lateral guide for the conductor to be connected. The actuating section is preferably designed as an actuating finger.

[0013] The clamping foot can have a second side tongue arranged laterally to the clamping tongue, wherein the clamping tongue can be arranged between the first side tongue and the second side tongue. This allows the clamping foot of the clamping spring to be symmetrically equipped with the two side tongues and the clamping tongue. This allows the clamping foot to be exerted on both sides of the clamping tongue during actuation by the actuating element via the two side tongues, thereby achieving a very uniform force distribution on the clamping foot of the clamping spring by means of the actuating element.

[0014] The actuating element preferably has two actuating sections arranged opposite one another, which can interact with two side tongues to actuate the clamping spring, wherein a free space can be formed between the two actuating sections for the conductor to be connected to pass through. If the clamping foot has two side tongues, the first actuating section of the actuating element can interact with the first side tongue, and the second actuating section of the actuating element can interact with the second side tongue. Due to the two actuating sections, the actuating element can be U-shaped, wherein the two actuating sections, spaced apart from one another, can form an opening in the form of a free space through which the conductor to be connected, and in particular also a section of the busbar, can pass. In this way, the two actuating sections prevent the conductor to be connected from being incorrectly inserted laterally to the right or left. The two actuating sections are preferably symmetrical to one another. The two operating sections preferably have a certain length in the operating direction of the operating element so that at any point in time, in particular in the open position and the clamping position of the clamping foot of the clamping spring, the operating section can laterally cover the conductor inserted into the housing and into the conductor connection cavity, so that the operating section can form a guide and lateral limit for the conductor to be connected at any point in time.

[0015] In order to fix the operating element in the open position and hold it firmly in its position, thereby preventing the operating element from being unexpectedly moved back into the clamped position, the operating element can preferably have a snap element and the retaining element can have a matching snap element so that the retaining element and the operating element are snapped together. The snap element and the matching snap element can be snapped together in a form-fitting manner in the open position of the clamp spring or the operating element. The operating element can, for example, have a recess as a snap element, into which a protrusion of the retaining element as a matching snap element can be snapped in the open position, or the retaining element can have a recess as a matching snap element, into which a protrusion of the operating element as a snap element can be snapped in the open position. In the open position, the operating element can be snapped together in a form-fitting manner. The recess can, for example, be configured in the form of an undercut. The protrusion can, for example, be configured in the form of a forwardly protruding arch. The protrusion can also be configured as a tongue. The shape of the protrusion preferably matches the shape of the recess, thereby preventing the protrusion from unexpectedly detaching from the recess. If the projection engages the recess, a snap fit is formed between the actuating element and the retaining element.

[0016] The holding element can be supported so as to be pivotable relative to the actuating element so that the holding element and the actuating element are disengaged. If the conductor to be connected abuts against the contact surface of the holding element, the holding element can be pivoted away from the actuating element in such a manner that the holding element and the actuating element are disengaged and the actuating element can be freely moved again from the open position to the clamped position.

[0017] To simplify the pivoting or tilting movement of the retaining element when applying the pressing force of the conductor to be connected to the pressing surface of the retaining element, the retaining element can be at least partially elastic. Due to the at least partial elasticity of the retaining element, the pressing force required by the conductor to be applied to the pressing surface in order to release the actuating element from its engagement with the retaining element can be reduced. This allows even flexible conductors with relatively small conductor cross-sections to be reliably connected with simple operation. The retaining element is preferably elastic in a region located outside the pressing surface, so that even with the elasticity of the retaining element, the pressing surface can be constructed with sufficient dimension stability.

[0018] The holding element can have, for example, an elongated shape. The holding element can preferably be web-shaped.

[0019] The retaining element can preferably have a first end section and a second end section, wherein the first end section can be supported with a press fit, while the second end section can move freely relative to the operating element. This allows the retaining element to be arranged fixedly, in particular, in a fixed position, relative to the operating element by the first end section. Press fit means that the first end section is supported so that it does not move at any time. Unlike the first end section, the second end section is not supported with a press fit, but is exposed, allowing it to move relative to the operating element. A pressure surface of the retaining element is preferably formed in the region of the second end section. The first end section is preferably formed on the retaining element opposite the second end section.

[0020] The press fit of the first end section of the retaining element can be formed by the housing of the wiring arrangement, wherein the first end section of the retaining element can be clamped in the housing. Since the retaining element is clamped in the housing, no additional fixing components are required to hold the retaining element. The retaining element can be clamped between two walls of the housing. This creates a press fit due to the clamping support of the retaining element in the housing. The housing can be designed to accommodate the retaining element, busbar, clamping spring, and actuating element, and the housing can include a conductor insertion opening for inserting the electrical conductor to be connected.

[0021] The object of the present invention is also achieved by a terminal block, in particular a terminal block, having at least one connection arrangement designed and improved as described above. The terminal block can be arranged, for example, on a printed circuit board. If the terminal block is designed as a terminal block, the terminal block can be arranged on a mounting rail.

[0022] Furthermore, a terminal arrangement can be provided, which can have a plurality of terminal arrangements arranged one behind the other, each of which can have at least one terminal arrangement designed and developed as described above.

[0023] The object of the present invention is also achieved by an electronic device having the wiring configuration constructed and improved as described above or the wiring terminal constructed and improved as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figures 1 to 5 A connection arrangement 100 is shown, which serves to connect electrical conductors (not shown here).

[0032] The terminal arrangement 100 has a housing 10 , which may be formed from an insulating material.

[0033] A conductor connection cavity 11 is formed in the housing 10. An electrical conductor inserted into the housing 10 can be clamped and electrically connected within the cavity. To insert the conductor into the cavity 11, the housing 10 has a conductor insertion opening 12 communicating with the cavity 11. The conductor to be connected can be inserted into the cavity 11 through the opening 12 along an insertion direction E.

[0034] A busbar 13 is provided in the conductor connection chamber 11 of the housing 10 , against which the conductor to be connected can be clamped, thereby electrically connecting the conductors. In order to clamp the conductor to be connected against the busbar 13 , a clamp spring 14 is further provided in the conductor connection chamber 11 .

[0035] The clamping spring 14 is designed as a leg spring. It has a retaining foot 15, a clamping foot 16, and an arcuate bent joint 17, wherein the bent joint 17 connects the retaining foot 15 to the clamping foot 16. The retaining foot 15 is arranged in a positionally stable manner in the conductor connection cavity 11. The clamping foot 16 is movable relative to the retaining foot 15, in particular, it is deflectable. Due to the deflectability of the clamping foot 16, the clamping foot 16 and the clamping spring 14 can be moved into an open position and a clamped position.

[0036] In such Figure 4 and Figure 5 In the open position shown, the clamping legs 16 are pivoted away from the current bar 13 , so that a free space is formed between the clamping legs 16 and the current bar 13 , into which a conductor to be connected can be inserted.

[0037] exist Figure 1 、 Figure 2 and Figure 3 , the clamping foot 16 is shown in the clamping position, wherein the clamping foot 16 rests on the current bar 13 without inserting the conductor 200 into the conductor connection cavity 11 and, with an inserted conductor, presses or clamps the conductor against the current bar 13 .

[0038] In order to move the clamping foot 16 from the clamped position into the open position, an actuating element 18 is provided, which is mounted in the housing 10 so as to be displaceable in a movement direction B. When the actuating element 18 is moved, the actuating element 18 performs a purely translational movement in the movement direction B, and thus along its longitudinal axis. When the clamping spring 14 and the clamping foot 16 of the clamping spring 14 are actuated, the actuating element 18 presses from top to bottom against the clamping foot 16 of the clamping spring 14.

[0039] The clamping foot 16 of the clamping spring 14 has a clamping tongue 19 and two side tongues 20, 21 arranged on either side of the clamping tongue 19. The clamping tongue 19 is arranged between the two side tongues 20, 21. A clamping edge 22 is formed on one free end of the clamping tongue 19, by means of which the clamping foot 16 and the clamping tongue 19 rest against the busbar 13 or a connected conductor in the clamped position.

[0040] The clamping foot 16 of the clamping spring 14 is actuated by means of the actuating element 18 via the two side tongues 20 , 21 extending parallel to the clamping tongue 19 , in that the actuating element 18 exerts a pressing force on the two side tongues 20 , 21 in the direction of movement B. Preferably, the actuating element 18 does not exert a pressing force on the clamping tongue 19 .

[0041] The length of the clamping tongue 19 is much greater than the two side tongues 20 , 21 , so that the clamping tongue 19 protrudes beyond the two side tongues 20 , 21 in the longitudinal direction of the clamping foot 16 .

[0042] The side tongues 20, 21 are all curved in the shape of a skateboard, while the clamping tongue 19 is straight.

[0043] The operating element 18 has two operating sections 23, 24 arranged parallel to each other, which interact with the two side tongues 20, 21. Due to the two operating sections 23, 24 arranged at a certain distance, the operating element 18 is U-shaped, wherein an opening in the form of a free space 25 is formed by the two operating sections 23, 24 at a certain distance, through which the conductor to be connected and a subsection 26 of the busbar 13 can pass, against which the conductor to be connected is clamped. The clamping tongue 19 of the clamping foot 16 also enters the free space 25 between the two operating sections 23, 24. Figure 3 and Figure 5 The sectional view of the actuating element 18 shows the free space 25 .

[0044] The two actuating sections 23, 24 prevent the conductor to be connected from being incorrectly inserted laterally to the right or left of the busbar 13. To this end, the two actuating sections 23, 24 have a length in the direction of movement B of the actuating element 18 such that at any point in time, in particular in the open position and the clamping position of the clamping legs 16 of the clamping spring 14, the actuating sections laterally cover the conductor inserted into the housing 10 and into the conductor connection chamber 11, so that the actuating sections 23, 24 form guides and lateral limits for the conductor to be connected at any point in time.

[0045] Furthermore, a holding element 27 is provided in the housing 10 , which engages with the actuating element 18 in the open position of the clamping spring 14 in order to hold the actuating element 18 and the clamping spring 14 (because the actuating element 18 presses against the clamping spring 14 ) in the open position.

[0046] The retaining element 27 has a pressing surface 28 that extends transversely or perpendicularly to the insertion direction E of the conductor into the housing 10. When the conductor is inserted into the conductor connection cavity 11, once fully inserted, the conductor presses against the pressing surface 28, causing the retaining element 27 to move away from the actuating element 18. This disengages the retaining element 27 from the actuating element 18, thereby releasing the locking engagement between the retaining element 27 and the actuating element 18. Due to the disengagement, the actuating element 18 can be pressed upward by the pressing force exerted by the clamping legs 16 on the actuating element 18, causing the actuating element 18 and the clamping spring 14 or the clamping legs 16 of the clamping spring 14 to automatically deflect from the open position into the clamping position, thereby clamping the inserted conductor against the busbar 13. The pressing surface 28 is aligned with the conductor insertion opening 12 and is therefore arranged in an extension of the conductor insertion opening 12. Therefore, when the conductor is inserted through the conductor insertion opening 12 into the conductor connection cavity 11, the conductor is guided to the pressing surface 28 of the retaining element 27. During this process, the conductor to be connected is passed through the free space 25 formed in the actuating element 18. The actuating direction R of the conductor to be connected against the pressing surface 28 of the holding element 27 is parallel to or extends along the insertion direction E of the conductor into the housing 10 of the connection arrangement 100.

[0047] The holding element 27 and the contact surface 28 of the holding element 27 are arranged behind the contact element 18, viewed in the actuation direction R. Therefore, the conductor to be connected is first passed through the actuation element 18 by its front end in the insertion direction E passing through the free space 25 through the actuation element 18 until it abuts the contact surface 28 of the holding element 27, preferably at an angle of 90°.

[0048] The holding element 27 is at least partially elastic, so that when the conductor is pressed against the contact surface 28, a deflection of the contact surface 28 is possible. If the conductor abuts against the contact surface 28 of the holding element 27, the holding element 27 or the contact surface 28 of the holding element 27 performs a deflection movement relative to the actuating element 18, in that the holding element 27 or the contact surface 28 is deflected away from the actuating element 28.

[0049] In order to realize the snap connection between the operating element 18 and the holding element 27 in the open position, the operating element 18 has a recess 29 in the technical solution shown here. The holding element 27 has a projection 30 facing the operating element 18, such as Figure 4 and Figure 5 As shown, this projection can engage in a positively locking manner in a recess 29 of the actuating element 18 in the open position.

[0050] For example, two projections 30 may be formed on the retaining element 27, and two recesses 29 may be formed on the actuating element 18. In this case, one of the two recesses 29 may be formed on one of the two actuating sections 23, 24 of the actuating element 18, so that each of the two actuating sections 23, 24 has a recess 29. In this case, the two projections 30 are preferably arranged at a distance in the transverse direction of the retaining element 27. The pressure surface 28 of the retaining element 27 may be formed between the two projections 30, so that the pressure surface 28 is delimited laterally, in particular on the right and left sides, as viewed in the transverse direction of the retaining element 27, by the projections 30.

[0051] The holding element 27 can be formed by an elastic sheet. To form the projection 30, the elastic sheet can have two freely stamped tongues, which are bent in a certain way to form the projection 30 toward the actuating element 18. The projections 30 can each be V-shaped, for example.

[0052] The retaining element 27 has a first end section 31 and a second end section 32 .

[0053] The holding element 27 is supported on the housing 10 with a press fit via a first end section 31 , in that the first end section 32 is arranged in a recess 33 of the housing 10 and is held clamped between walls 34 , 35 of the recess 33 which delimit the recess 33 .

[0054] The second end section 32 of the retaining element 27 is mounted so as to be freely movable relative to the actuating element 18. A contact surface 28 is formed on the second end section 32. A projection 30 is also formed on the second end section 32. The retaining element 27 is arranged with its second end section 32 between the actuating element 18 and another section 36 of the busbar 13. This section 36 is perpendicular to the section 26 of the busbar 13 against which the conductor to be connected is clamped.

[0055] The housing 10 has a channel 36 in which the operating element 18 is guided. The channel 37 is substantially perpendicular to the conductor insertion opening 12. Both the channel 37 and the conductor insertion opening 12 are connected to the conductor connection chamber 11.
