Technical Field

[0001] The invention relates to a terminal for connecting electrical conductors by means of spring-force clamping, wherein the terminal is provided for fastening to a busbar. Background Art

[0002] Such a terminal clamp is known from DE 10 2013 107 292 A1. Summary of the Invention

[0003] The basic object of the present invention is to further optimize such a terminal.

[0004] This object is achieved by a terminal for connecting electrical conductors by means of spring-force clamping, wherein the terminal is designed to be plugged onto a busbar, wherein the terminal comprises: at least one spring-force clamping interface with a clamping spring for clamping the electrical conductor; a housing at least partially surrounding the spring-force clamping interface, the housing having a conductor insertion opening; and a pivotably mounted actuating lever designed to actuate at least a portion of the clamping spring, wherein a receiving cavity for accommodating at least a section of a busbar is provided in the housing, onto which the terminal can be plugged. In this way, the terminal according to the invention can be realized with a simple and compact design. Simple and reliable lever actuation is possible by means of reliable clamping. The terminal allows for simple locking or other placement onto the busbar.

[0005] The electrical conductor to be clamped can be introduced into the housing along a conductor insertion direction through the conductor insertion opening and directed to the clamping point of the spring-force clamping interface. A conductor insertion channel can be connected to the conductor insertion opening within the housing. According to an advantageous embodiment of the present invention, the conductor insertion channel and the receiving cavity are arranged relative to each other so that they transition into each other, allowing a busbar accommodated in the receiving cavity to at least partially extend into the conductor insertion channel.

[0006] According to an advantageous embodiment of the present invention, at least one region of the operating lever adjoins or protrudes into the busbar's receiving cavity. In this way, the operating lever can at least partially use the busbar's surface as a support and sliding surface during the pivoting movement. This simplifies the design of the terminal clamp, as the supporting of the operating lever, particularly for the pivoting movement, requires less effort in the terminal clamp's structural design.

[0007] According to an advantageous embodiment of the present invention, at least a portion of the operating lever can be supported on a busbar accommodated in the accommodating cavity at least during the pivoting movement of the operating lever. As a result, the operating lever can conduct current at least partially on and along the surface of the busbar during the pivoting movement.

[0008] According to an advantageous embodiment of the present invention, the terminal clamp includes a positioning element for positioning the busbar relative to the receiving cavity in an installation orientation, in which the busbar is arranged at an angle relative to the wire insertion direction. In this way, the positioning element defines a specific orientation of the section of the busbar located in the receiving cavity relative to the wire insertion direction and, therefore, also relative to the clamped electrical conductor. The positioning element thus allows the busbar to be fixed in the installation orientation. Due to this installation orientation of the busbar, the electrical conductor is not arranged parallel to the busbar, but rather at an angle, for example, an acute angle, relative to the busbar. The angle between the wire insertion direction and the surface of the busbar facing the electrical conductor can, for example, be in the range of 5 to 45 degrees. This allows for particularly reliable clamping of the electrical conductor, wherein the section of the busbar located in the receiving cavity can be used to clamp the electrical conductor. By guiding the electrical conductor at an angle relative to the busbar surface, surface support of the electrical conductor on the busbar is avoided.

[0009] According to an advantageous embodiment of the present invention, the positioning element comprises one or more locking elements, via which the terminal clamp can be lockedly connected to the busbar. This allows for simple locking of the terminal clamp to the busbar. The terminal clamp can be designed in such a way that the positioning elements do not need to be manually actuated separately in order to connect the terminal clamp to the busbar. The housing of the terminal clamp can be designed as a housing composed of one or more components, wherein the housing can be rigidly constructed as a whole from one or more of its components. A hinge for opening or closing the housing is not required.

[0010] According to an advantageous embodiment of the present invention, the receiving cavity extends completely through the terminal clamp in a transverse direction extending perpendicularly to the conductor insertion direction. The housing of the terminal clamp can be designed, for example, as an insulating material housing, which is laterally open in the region of the receiving cavity. Accordingly, the terminal clamp can also be plugged onto busbars having a relatively large longitudinal extent.

[0011] According to an advantageous embodiment of the present invention, the clamping spring comprises a contact leg, a spring bow connected to the contact leg, and a clamping leg connected to the spring bow for clamping the electrical conductor. The clamping spring is supported by the contact leg on a portion of the terminal clamp relative to the clamping force of the clamping leg. The clamping force of the clamping leg allows the electrical conductor to be securely clamped. For this purpose, the terminal clamp can, for example, comprise a busbar against which the electrical conductor is pressed by the clamping leg, or a surface area of the busbar can be used to clamp the electrical conductor. The clamping leg can act directly on the busbar or via one or more additional elements, such as the busbar and / or the clamped electrical conductor.

[0012] According to an advantageous embodiment of the present invention, the terminal clamp includes a retaining frame, on which the contact leg is retained, for example, by being received, hooked in, or fixed to the retaining frame. The retaining frame can be configured, for example, as a metal part. The retaining frame can have an opening circumferentially surrounded by a connecting piece, through which at least one free end of the electrical conductor to be clamped can be guided. The contact leg can, for example, be hooked in on the inner circumference of the opening in the retaining frame.

[0013] According to an advantageous embodiment of the present invention, the retaining frame comprises a traction element or is coupled to a traction element. The busbar can be supported on the traction element in the receiving chamber relative to the clamping force acting on the busbar by the clamping legs. The traction element, which can be designed as a drawbar, can transmit pure traction force from the busbar to the fastening point of the contact legs. The spring-loaded clamping interface can be held on the busbar in a self-supporting manner via the traction element. In this self-supporting system, no force from the clamping spring is transmitted to the housing, or only a negligible force is transmitted to the housing. This makes it possible, in particular, to achieve a closed force flow between the traction element, retaining frame, and busbar.

[0014] According to an advantageous embodiment of the present invention, the free ends of the clamping legs are positioned so that a clamping point for clamping the electrical conductor is formed between the surface of the busbar located in the receiving cavity that faces the clamping leg and the free end. In this way, the busbar can be used as a clamping surface for the electrical conductor. Accordingly, the terminal clamp can be designed without its own busbar, that is, without a busbar. This further simplifies the design of the terminal clamp.

[0015] According to an advantageous embodiment of the present invention, an electrical conductor clamped at the clamping point can be clamped between the free ends of the clamping legs and the corner edge of the busbar. This allows for particularly secure clamping of the electrical conductor at the clamping point. To this end, the receiving cavity can include a positioning element that positions the busbar received in the receiving cavity such that the corner edge is positioned relative to the free ends of the clamping legs so that the clamped electrical conductor can be clamped between the free end and the corner edge.

[0016] The clamping legs can have a clamping edge at their free ends, thereby further improving the reliability of the clamping of the electrical conductor.

[0017] According to an advantageous embodiment of the present invention, the housing has an insertion opening through which a busbar segment can be inserted into the receiving cavity of the terminal clamp. The insertion opening can be provided on the same side of the housing as the conductor insertion opening or on a side of the housing facing away from the operating side of the terminal clamp. The operating side of the terminal clamp is the side on which the manual operating element of the operating lever is accessible for manual operation. This makes it particularly easy to insert the busbar segment into the receiving cavity or to simply plug the terminal clamp onto the busbar.

[0018] According to an advantageous embodiment of the present invention, the operating lever is U-shaped when viewed in the conductor insertion direction. The operating lever comprises a first and a second support disc, each of which is connected to one another via a connecting region of the operating lever. A gap exists between the first and second support discs for threading the electrical conductor to be clamped. This design allows the operating lever to transmit the operating force to the clamping spring in a compact configuration. Furthermore, the overall terminal clamp can be very compact, as the gap between the support discs can be used to thread the electrical conductor.

[0019] The first and second support disks can, for example, rest on a surface of the busbar and slide down said surface when a pivoting movement of the actuating lever is performed.

[0020] According to an advantageous embodiment of the present invention, the U-shaped portion of the operating lever has an open side, which is positioned so that it can be covered by the surface of the busbar accommodated in the accommodating cavity. As a result, the open side of the U-shape can be closed by the busbar accommodated in the accommodating cavity.

[0021] According to an advantageous embodiment of the present invention, the first and second support discs form guides for guiding the electrical conductor through the gap in any operating position of the operating lever. Accordingly, guidance for the electrical conductor is already provided by the operating lever. This guidance is ensured by the first and second support discs in any operating state of the terminal clamp, in particular in any pivoting position of the operating lever. The terminal clamp may include additional conductor guide elements, as explained below.

[0022] According to an advantageous embodiment of the present invention, the connecting clamp has only a single spring for the corresponding spring-force clamping interface, namely the clamping spring of the spring-force clamping interface. This results in a simple design of the connecting clamp and comprises only a few components. This simplifies the manufacture and assembly of the connecting clamp.

[0023] According to an advantageous embodiment of the present invention, the clamping spring is essentially V-shaped. This allows the spring-force clamping interface to be configured as a direct plug-in interface. In a direct plug-in interface, if the conductor is sufficiently rigid (e.g., a single-wire conductor), the conductor can be directly introduced into the clamping location without operating an actuating lever and securely clamped by the clamping legs. The actuating lever is only required to remove the clamped conductor from the clamping location.

[0024] The operating lever can, for example, have an open position and a closed position. In the open position, the clamping point is opened, that is, the clamping legs are removed from the clamping counterpart (e.g., a busbar or busbar), so that the electrical conductor can be introduced into or removed from the clamping point without exerting force. In the closed position, the clamping legs are effective in securing the electrical conductor to the clamping point.

[0025] The operating lever can be supported in the terminal clamp in a displaceable and / or floating manner, particularly in its support region. In particular, when no busbar is arranged in the receiving chamber, the operating lever can assume a slightly different position in the terminal clamp in its support region than when the busbar is arranged in the receiving chamber. In other words, by inserting the busbar in the receiving chamber, the operating lever can be pressed to a certain (usually relatively small) extent by the busbar in its support region.

[0026] In the sense of the present invention, the indefinite article "a" is not to be understood as a quantifier. That is, if, for example, a component is discussed, this is to be interpreted as "at least one component." Whenever an angle specification is given in degrees, it relates to a circumferential dimension of 360 degrees (360°).

[0027] Hereinafter, the present invention will be described in detail based on embodiments using the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] exist Figure 1 The terminal 1 shown in FIG has a housing 2, a clamping spring 4, an actuating lever 5, and a retaining frame 6. The housing 2 can, for example, be constructed in two parts, comprising a first housing component 20 and a second housing component 21. The first and second housing components 20, 21 can be fixed to one another via locking elements, for example by latching them to one another. The clamping spring 4 and the retaining frame 6 are arranged in the area enclosed by the housing 2. Figure 1 Additionally shown are busbars 3 , to which the terminal clamps 1 are fastened.

[0076] The housing 2 has a conductor receiving chamber 22, a conductor insertion opening 23, an installation opening 24, a receiving cavity 25 for receiving a section of the busbar 3, and positioning elements 26, 27, and 28 for positioning the busbar 3 in a defined installation position relative to the receiving cavity. The conductor receiving chamber 22 can, for example, be formed by a portion of the second housing component 21, while the remaining elements of the housing 2 can be formed on the first housing component 20. The conductor insertion opening 23 is located on the conductor insertion side 11 of the terminal 1. A conductor insertion channel 98 is connected to the conductor insertion opening 23 within the housing 2 and can, for example, be at least partially enclosed by a wall of the housing 2.

[0077] The electrical conductor to be connected to the terminal 1 can be guided along the conductor insertion direction L through the conductor insertion opening 23 to the clamping position to be described below. The insertion opening 24 is used to insert the section of the busbar 3 into the receiving cavity 25. If the section of the busbar 3 is completely inserted, then Figure 1 , in which the receiving chamber 25 is filled as much as possible by the section of the busbar 3. As can be seen, the busbar 3 at least extends into the conductor insertion channel 98 for at least a distance.

[0078] The positioning elements 26, 27 can be designed, for example, as mutually opposed sliding edges of the housing 2, on which the busbar is introduced through the insertion opening 24 into the receiving chamber 25 during its installation and ultimately held in the installed position. The positioning element 28 can be designed as a locking element, which is arranged on a resilient locking tongue of the housing 2. The locking tongue bends slightly when the busbar 3 is installed and then snaps back into the receiving chamber 25 when the installed position of the busbar 3 is reached, thereby securing the busbar 3 in the receiving chamber 25 by locking. On the side facing away from the positioning element 28, the position of the busbar 3 can be fixed, for example, by a holding frame 6.

[0079] The clamping spring 4 includes a contact leg 41, a spring bow 42 connected to the contact leg 41, and a clamping leg 43 connected to the spring bow 42. The contact leg is fixed to the holding frame 6 via its free end 40 and supported there, for example, by being hooked behind a connecting piece 60 of the holding frame 6. The connecting piece 60 can thus form a first support element 60 for accommodating the contact leg 41. The clamping leg 43 terminates at a free end 44, which may have a clamping edge. The free end 44 or the clamping edge can be used to clamp an electrical conductor to the surface 30 of the busbar 3. The clamping point of the spring-force clamping terminal thus achieved is formed between the free end 44 or the clamping edge of the clamping leg 43 and the surface 30 of the busbar 3. The clamping point can be formed, in particular, with the aid of a corner edge 31 of the busbar 3.

[0080] The holding frame 6 has a cutout 61. The electrical conductor to be clamped is introduced through the conductor insertion opening 23 and is initially guided through a conductor insertion channel 98 connected to the conductor insertion opening 23. In the region of the actuating lever 5, the electrical conductor is guided through the supporting discs 52, each of which is arranged laterally. The clamping legs 43 and the surface 30 of the busbar 3 also contribute to the conductor guidance. The electrical conductor can be introduced through the cutout 61 into the conductor receiving chamber 22, which also forms an end stop for limiting the insertion depth of the electrical conductor.

[0081] The holding frame 6 extends further below the cutout 61 via a pulling element 62, behind which the busbar 3 is hooked. The pulling element 62 can, for example, terminate in a bent free end, which forms a second support 99 on which the busbar 3 rests. The clamping spring 4 transmits the clamping force directly or indirectly to the busbar 3 via the clamping legs 43. The busbar 3 is supported against this clamping force by the pulling element 62, which is also connected to the contact legs 41 via the holding frame 6. This achieves a self-supporting contact insertion of the terminal 1.

[0082] The operating lever 5 is accessible on the operating side 10 of the terminal 1 for manual operation. The operating lever 5 has a manual operating element 50, at which the operating lever 5 can be manually operated. The operating lever 5 transitions from the manual operating element 50 to an area in which the operating lever 50 branches into a side wall 51 arranged on the left and right. The side walls 51 can also extend laterally, for example, beyond the retaining frame 6. Corresponding spring operating bodies are mounted on the inner sides of the side walls 51 facing each other, on which a first and a second support disc 52 are respectively arranged. The operating lever 5 is pivotally, that is, rotatably, supported in the terminal 1 via the support disc 52 and can in particular be supported on the surface 30 of the busbar 3. In this case, the operating lever 5 together with the support disc 52 slides down on the busbar 3 during the pivoting movement.

[0083] The spring operating bodies each have a V-shaped cutout, by which the corresponding operating edge 53 is formed. The operating edge 53 acts on the clamping leg 43. Figure 1 The closed position shown in FIG is pivoted into the open position by pivoting the operating lever counterclockwise by approximately 90 degrees, whereupon the clamping leg 43 is deflected upwards toward the abutment leg 41 by the operating edge 53, whereby the free end 44 or the clamping edge continues to move away from the busbar 3.

[0084] Figure 2 The connecting clamp 1 is shown in a plan view on the conductor insertion side 11. The busbar 3 extends completely through the housing 2 in the transverse direction Q, ie the receiving space 25 also extends completely through the connecting clamp 1 in the transverse direction Q.

[0085] Figure 3 Show the basis Figure 1 This is a sectional view of the terminal 1 along the section line AA. The elements already explained are additionally explained. Figure 3 It can be seen in particular that the holding frame 6 has a recess 61 which is delimited by the webs 60 , 63 , 64 and, at the bottom on the side of the recess 61 opposite the web 60 , by a region for connecting the traction element 62 .

[0086] Figure 4 An alternative embodiment of locking and fixing the busbar 3 by means of a positioning element 28 is shown. Figure 4 In the embodiment of FIG. 2 , the positioning element 28 is led from the first housing component 20 to the side edge of the busbar 3 via an arm bent in a U-shape.

[0087] In the embodiments of the terminal 1 described so far, the insertion opening 24 is arranged on the same housing side of the housing 2 as the conductor insertion opening 23, namely on the conductor insertion side 11, whereas depending on the embodiment of the terminal 1 Figures 5 to 7 The embodiment shown in FIG. 1 illustrates a variant in which the insertion opening 24 is arranged on the housing side of the housing 2 facing away from the operating side 10. In other words, Figures 5 to 7 In the embodiment of FIG, a section of the busbar 3 is introduced into the housing 2 , so to speak, from below.

[0088] It can be seen that in this case only the locking elements 26, 28 are present. The busbar 3 is introduced into the receiving chamber 25 so that it is first pushed between the free end 44 of the clamping leg 43 and the pulling element 62 and then locked behind the locking element 28 by means of a tilting movement. In order to ensure sufficient movability of the locking tongue connected to the locking element 28, the housing 2, in particular the first housing part 20, can have an elongated groove or cutout 29.

[0089] Especially through Figure 6 As shown in FIG, the positioning element 28 does not have to be a locking element extending in the transverse direction Q, but can be realized by two individual locking elements in the region of the side walls of the housing 2, which are connected to each other by a transverse web below the inserted busbar 3. A tool, such as a screwdriver, can be inserted into the gap or opening thus formed in order to deflect the positioning element 28 and release the locking connection between the housing 2 and the busbar, so that the terminal 1 can be removed from the busbar.

[0090] In addition, according to Figures 5 to 7 The terminal is designed similarly to the first-described embodiment.
