Description

[0001] The invention relates to a conductor connection terminal with an insulating housing, a busbar, a clamping spring and an actuating element, wherein the clamping spring has a contact leg, a spring arch and a clamping leg, wherein the clamping leg with the busbar forms a clamping point for an electrical conductor that can be inserted into the conductor connection terminal, wherein the clamping leg is displaceable between an open position and a closed position for opening and closing the clamping point, wherein the conductor connection terminal is designed for an automatic displacement of the clamping leg into the closed position when an electrical conductor is inserted into the conductor connection terminal and wherein the actuating element is designed to displace the clamping leg into the open position.

[0002] Such conductor terminals are well known in practice. These are conductor terminals with an automatic connection of the electrical conductor to be clamped when it is inserted into the conductor terminal. Inserting the electrical conductor automatically releases the clamping leg of the clamping spring, which is held in the open position, thereby clamping the electrical conductor. The actuating element of the conductor terminal serves to return the clamping leg to the open position to open the clamping point, for example, to release a clamped conductor.

[0003] With regard to the actuating element, it is desirable that it be designed to transmit sufficient force to the clamping leg of the clamping spring while simultaneously being easy to operate with minimal effort. The limited space available in compact conductor terminal blocks can further exacerbate the technical challenge of meeting these conflicting requirements.

[0004] Against this background, the object of the invention is to create an improved conductor connection terminal with simple handling and a reliably effective actuating mechanism.

[0005] The object is achieved with a conductor connection terminal according to claim 1. Advantageous embodiments are disclosed in the subclaims, the description and the figures.

[0006] According to the features of independent claim 1, a conductor connection terminal is proposed with an insulating housing, a busbar, a clamping spring and an actuating element, wherein the clamping spring has a contact leg, a spring arch and a clamping leg, wherein the clamping leg forms a clamping point with the busbar for an electrical conductor that can be inserted into the conductor connection terminal, wherein the clamping leg is displaceable between an open position and a closed position for opening and closing the clamping point, wherein the conductor connection terminal is designed for an automatic displacement of the clamping leg into the closed position upon insertion of an electrical conductor into the conductor connection terminal and wherein the actuating element is designed to displace the clamping leg into the open position,wherein the actuating element is pivotally mounted in the insulating housing and is designed to displace the clamping leg into the open position by a pivoting movement of the actuating element, and wherein the actuating element has, on a first side of the actuating element, a support section for support on the insulating housing and, on a second side of the actuating element opposite the first side, a pivot bearing and an actuating section for contact with the clamping leg of the clamping spring.

[0007] In other words, a conductor connection terminal with automatic conductor connection and a return of the clamping leg to the open position by a pivoting actuating element is proposed. This actuating element enables effective and powerful displacement of the clamping leg with high operating comfort and low installation space requirements through a compact arrangement of the pivot bearing and actuating surface on one side and opposing support of the actuating element on the insulating housing. Furthermore, as will be explained in more detail below in connection with advantageous embodiments, with the proposed actuating element, a comparatively solid actuating element can be obtained with appropriate spacing of the first and second sides of the actuating element from one another. This increases the robustness of the actuating element, thus creating a durable conductor connection terminal.Particularly in conductor terminals with automatic conductor connection, where the clamping leg automatically moves into its closed position due to spring force, high forces can briefly act on an actuating section of the actuating element adjacent to the clamping leg. Therefore, increased robustness of the actuating element can be particularly advantageous for conductor terminals with automatic clamping leg displacement. Furthermore, a comparatively solid actuating element is easy to operate and enables reliable force transmission. The pivoting mobility of the actuating element creates a lever effect, which allows the clamping leg to be returned to the open position with minimal force.In this case, an operating force acting on the actuating element can be converted into a restoring force acting on the clamping leg by means of the pivoting movement and the actuating section.

[0008] The insulating housing of the conductor terminal, made, for example, from a plastic material, accommodates the conductor rail and clamping spring of the conductor terminal and protects them from environmental influences and contact. Depending on the design, as will be explained below, the insulating housing or the actuating element can have a conductor insertion channel for inserting the electrical conductor into the insulating housing. The conductor insertion channel can form an insertion channel leading to the terminal point of the conductor terminal, for example, one that is at least partially cylindrical or funnel-shaped, into which an end section of the electrical conductor can be inserted into the insulating housing in a defined insertion direction and removed from the insulating housing in the opposite direction to the insertion direction.The busbar, also called contact piece or current bar, can be a largely rigid electrical conductor, which is formed, for example, by a metal strip, which can be partially bent to form a terminal point according to favorable design options or can have a hole collar produced by pulling through.

[0009] The clamping spring of the conductor connection terminal can be a predominantly flat component with a significantly greater length and width than depth or thickness, and can be made, in particular, of an elastically resilient material. The clamping spring has a contact leg for supporting the clamping spring on the insulating housing, a clamping leg for clamping the conductor to the busbar, and a spring arch between the contact leg and the clamping leg for deflecting the clamping spring, so that the contact leg can run opposite the clamping leg, at least in sections. When shifted to its open position, the clamping leg can be shifted toward the contact leg.The clamping leg can form a clamping point with the busbar for clamping the electrical conductor to the busbar. The conductor is pressed against the busbar by the clamping leg using the spring force of the clamping spring, thus establishing a reliable electrical contact. The clamping leg can be moved between an open position and a closed position to open and close the clamping point. In the open position of the clamping leg, it is spaced apart from the busbar and any inserted electrical conductor, allowing the clamping point to be released and the conductor to be inserted into the conductor connection terminal, as well as positioned in the area of ​​the clamping point or removed from it.In the closed position, the clamping leg is moved toward the busbar and the inserted electrical conductor, exerting a contact force on the electrical conductor in the direction of the busbar, thus establishing electrical contact between the conductor and the busbar. When moving from the open position to the closed position, the actuating element can be automatically pivoted by a force transmitted from the clamping leg to the actuating element.

[0010] To achieve automatic conductor connection, the conductor connection terminal is designed for automatic movement of the clamping leg into the closed position upon insertion of the electrical conductor into the insulating housing. For this purpose, the conductor connection terminal has, in particular, a release mechanism that can be actuated by the inserted conductor and by means of which the clamping leg can be released from its open position and automatically moved into the closed position due to spring force. In its open position, the clamping leg can be held in a standby state, for example, by a suitable retaining structure on the busbar or on an extended contact leg of the clamping spring, as will be explained in more detail below using corresponding embodiments.

[0011] The actuating element of the conductor terminal can be a component that is at least partially embedded in the insulating housing and pivotably mounted in the insulating housing. The actuating element is configured to interact with the clamping leg of the clamping spring via the actuating section and is designed to move the clamping leg into the open position. The actuating element can be operated by a user via an operating section of the actuating element that is accessible from the vicinity of the conductor terminal. Depending on the selected embodiment, the operating section can be configured for manual, tool-free actuation and / or for tool-based actuation, whereby a screwdriver, for example, can be a suitable actuating tool.

[0012] The insulating housing can have an actuating channel into which the actuating element is embedded. The actuating element can be supported during a pivoting movement, at least via the support section on the first side of the actuating element, on a support surface of the insulating housing, for example, on a support surface of the actuating channel. Depending on the embodiment, the first side or the support section of the actuating element can have a flat or a curved surface. The pivot bearing of the actuating element, arranged on the second side of the actuating element opposite the first side, enables the actuating element to be pivoted about a rotational axis extending through the actuating element or the insulating housing.Depending on the design, the actuating element is supported via the pivot bearing on the insulating housing or the spring arch of the clamping spring, and can slide with a surface of the pivot bearing on an opposite surface of the insulating housing or the spring arch. The actuating section on the second side of the actuating element is designed to displace the clamping leg of the clamping spring into its open position and, for this purpose, bears against the clamping leg at least in sections. The contact surface between the actuating section and the clamping leg can change, in particular increase, during a displacement of the clamping leg from the closed position to the open position.Accordingly, according to one possible embodiment, the actuating section can bear against the clamping leg with a larger surface area in the open position of the clamping leg than in the closed position of the clamping leg, so that the actuating section bears increasingly against the clamping leg as the clamping leg is increasingly shifted into the open position. By means of the actuating section, a compressive force can be exerted on the clamping leg during a pivoting movement of the actuating element in order to displace it. According to one possible embodiment, the actuating section can be configured to slide on the clamping leg during a displacement of the clamping leg, i.e., to move relative to the clamping leg. The first and second sides of the actuating element can refer to two opposing surfaces of the actuating element.The support portion, the actuating portion and the pivot bearing may be formed integrally with the actuating element.

[0013] According to one embodiment, at least in sections, the first side of the actuating element can be spaced apart from the second side opposite the first side by a distance that corresponds to at least one spring arc width of the spring arc of the clamping spring. The spring arc width can be a measure of the maximum distance between the two spring legs describing the spring arc, or in other words, a distance between the clamping leg and the contact leg at a transition region into the spring arc. Accordingly, the actuating element can, at least in sections, have a width that corresponds to the spring arc width or exceeds the spring arc width.If the actuating element is conceptually divided into a pivoting area with the pivot bearing and an actuating area adjoining the pivoting area with the actuating section, the actuating element can have a width, particularly in the pivoting area, corresponding to the distance between the first and second sides, which corresponds at least to the spring arc width of the spring arc of the clamping spring. With an actuating element that has a width, at least in sections, corresponding to or exceeding the spring arc width, a comparatively solid and robust actuating element is obtained, which is characterized by ease of use and reliable force transmission to the clamping leg of the clamping spring.

[0014] According to one embodiment, the pivot bearing of the actuating element can be arranged between the spring arc of the clamping spring and a conductor entry side of the insulating housing. This enables a compact arrangement with favorable pivot angles of the actuating element. According to one possible design, an apex of the spring arc of the clamping spring can point in the direction of the pivot bearing. The conductor entry side of the insulating housing can be a housing side of the insulating housing, which can be defined, for example, by a housing surface of the insulating housing, at which side the electrical conductor can be inserted into the conductor connection terminal. In particular, a conductor entry opening can be provided on the conductor entry side, which, depending on the embodiment, can be arranged in the insulating housing or in the actuating element.The pivot bearing can, for example, be arranged opposite an outer circumferential surface of the spring arch of the clamping spring, wherein, depending on the embodiment, a free space or housing material of the insulating housing can be present between the outer circumferential surface of the spring arch and the pivot bearing.

[0015] According to one embodiment, the pivot bearing can be arranged, starting from an apex of the spring arc, in a housing area of ​​the insulating housing facing the clamping leg. This allows reliable displacement of the clamping leg even with small pivot angles of the actuating element. In other words, the pivot bearing can be arranged closer to the clamping leg than to the contact leg of the clamping spring in the insulating housing.

[0016] According to an alternative embodiment, the pivot bearing can be arranged, starting from an apex of the spring arc, in a housing area of ​​the insulating housing facing away from the clamping leg. In other words, the pivot bearing can be arranged closer to the contact leg than to the clamping leg of the clamping spring in the insulating housing. This allows a greater leverage effect to be achieved with the actuating element and thus a higher force conversion to be achieved. This can be facilitated, for example, by an embodiment explained below, according to which the pivot bearing is spaced from the second side of the actuating element by a pivot arm protruding from the second side of the actuating element.

[0017] According to one embodiment, the pivot bearing of the actuating element can be designed as a pivot pin received in a bearing recess of the insulating housing. The pivot pin can, for example, be cylindrical or partially cylindrical in its basic shape, and the bearing recess can, for example, be a corresponding cavity in the insulating housing. This enables a structurally simple yet defined pivotable mounting of the actuating element in the insulating housing. In this case, an axis of rotation about which the actuating element can pivot can run through a longitudinal axis of the pivot pin.

[0018] Alternatively, it is conceivable, for example, for the pivot bearing of the actuating element to be designed as a support section of the actuating element resting on a bearing projection of the insulating housing or on the spring arch of the clamping spring. This also makes it possible to achieve a structurally simple yet defined pivotable mounting of the actuating element in the insulating housing. In this embodiment, the support section can have a concave contour with which the actuating element can slide on the bearing projection of the insulating housing, which can have, for example, a spherical or partially cylindrical convex surface, or on the spring arch during a pivoting movement. A concave contour is an inwardly curved contour. The support section can, in particular, be curved with a radius that essentially corresponds to the radius of the bearing projection of the insulating housing or the radius of the spring arch.In this embodiment, an axis of rotation about which the actuating element can pivot can run through the bearing projection of the insulating housing or an adjacent region of the insulating housing or through a clamping spring interior which is framed by the spring arch as well as the contact leg and the clamping leg.

[0019] According to one embodiment, the actuating element can have a conductor insertion channel through which the electrical conductor can be inserted into the conductor connection terminal. Thus, an actuating element with an integrated conductor insertion is provided, whereby a particularly compact conductor connection terminal is obtainable, since no separate conductor insertion channel needs to be provided in the insulating material housing. The electrical conductor can be guided to the clamping point of the conductor connection terminal via the conductor insertion channel. Upon actuation of the trigger mechanism, which leads to a displacement of the clamping leg into the closed position, the actuating element can be pivotable together with the electrical conductor inserted into the conductor insertion channel.In addition, when the clamping leg is manually moved into the open position using the actuating element, the actuating element can be pivoted together with the electrical conductor inserted into the conductor insertion channel. In this embodiment, the actuating element can be designed as a hollow body, allowing the electrical conductor to be guided through the actuating element.

[0020] Alternatively, it is conceivable, for example, for the insulating housing to have a conductor entry channel for inserting the electrical conductor into the conductor connection terminal and an actuating channel extending essentially parallel to the conductor entry channel for receiving the actuating element. This allows the functions of conductor entry and actuation of the actuating element for displacing the clamping leg to be clearly separated from one another in terms of design and do not influence one another. The essentially parallel alignment of the conductor entry channel and the actuating channel enables a compact design of the conductor connection terminal. The actuating channel can have a shape adapted to the outer contour of the actuating element, at least in sections. The actuating element received in the actuating channel can be accessible at least using a suitable tool.The actuating element can be movably arranged in the actuating channel, in particular can be displaceable along the actuating channel. The actuating channel can have a cross-section at least half as large as the conductor insertion channel, at least in sections. The actuating element can be designed to be so solid that it essentially completely fills the actuating channel, at least in sections, with regard to its cross-section, i.e. its width from the first to the second side of the actuating element corresponds to a channel width of the actuating channel. According to one embodiment, it can be provided that, at least in sections, the first side of the actuating element is spaced from the second side opposite the first side by a distance that corresponds to at least half a channel width of the conductor insertion channel. In particular, the distance can correspond to at least 60% or at least 70% of the channel width.In other words, the actuating element can be designed to be so solid that its width, at least in sections, is at least half the channel width of the conductor entry channel. A channel width of the conductor entry channel or of the actuating channel can correspond to a distance between two opposing channel wall surfaces and can be described, for example, by a diameter of the conductor entry channel or of the actuating channel. If the conductor entry channel has a varying channel width, for example due to a funnel-shaped section, the channel width in question can be related to the largest channel width of the conductor entry channel. As described above, a comparatively solid actuating element can enable a robust and reliably effective resetting of the clamping leg of the clamping spring.

[0021] According to one embodiment, the actuating element can be designed as a pivoting handle. This implements an intuitive and easy-to-use actuating element. A pivoting handle is understood to be an actuating element that is actuated and pivoted by the action of a pressure force applied manually or by a tool. In other words, the pressure force generates a torque that causes the actuating element to pivot. According to one possible design, the pivoting handle is only operated to move the clamping leg into the open position. When the clamping leg is automatically moved into the closed position, the pivoting handle can be automatically moved to its starting position, where it can be actuated again by pressure force.

[0022] According to one embodiment, the busbar can have a release mechanism with a retaining tab for holding the clamping leg in its open position and with a release surface for releasing the clamping leg when the inserted electrical conductor touches the release surface. This allows the clamping leg to be temporarily secured to the busbar until an electrical conductor inserted into the conductor connection terminal touches the release surface of the busbar, thereby triggering an automatic displacement of the clamping leg into the closed position. The release surface can be a side frame of the busbar extending from a clamping area of ​​the busbar for clamping the conductor in the direction of the contact leg, on which side frame the retaining tab is arranged. The retaining tab can engage over a side edge of the clamping leg and thus hold it laterally.If the inserted electrical conductor touches the side frame of the busbar, which forms the release surface, the side frame can deflect laterally, causing the clamping leg to disengage from the retaining tab and automatically move into its closed position due to the spring force of the clamping spring. By integrating the release mechanism into the busbar, the clamping spring can be optimized for its function as a clamping element for clamping the electrical conductor.

[0023] Alternatively or in addition to the previously described embodiment, it is conceivable for the contact leg of the clamping spring to have a release mechanism with a holding section for holding the clamping leg in its open position and with a release section for releasing the clamping leg when the electrical conductor strikes the release section. This allows the clamping leg to be temporarily secured to the contact leg in its open position until an electrical conductor inserted into the conductor terminal triggers an automatic displacement of the clamping leg into the closed position. The holding section can have a retaining projection to which the clamping leg can be temporarily secured with its free end or with a retaining lug additionally provided on the clamping leg in the manner of a latch.The holding section of the contact leg can, for example, branch off at a bend from a contact section of the contact leg provided for supporting the contact leg on the insulating material housing and adjoining the spring arch, in particular be angled or bent from this. According to one possible design, the holding section can run substantially perpendicular to the contact section. The release section can, for example, have a release surface that can extend substantially perpendicular to an insertion direction of the electrical conductor into the conductor connection terminal.Impact of the conductor on the release surface can lead to a displacement of the release section and, for example, to an associated stretching or displacement of the holding section, which can cause the retaining tab of the clamping leg to release from a retaining projection of the holding section, thereby activating the automatic displacement of the clamping leg into the closed position. In other words, for example, a locking of the clamping leg to the contact leg can be released by applying pressure to the release section. The clamping spring can be designed such that even a slight displacement of the release section by a flexible conductor end triggers the automatic displacement of the clamping leg into the closed position, for example, by a comparatively small dimensioning of the retaining projection on the holding section. The release section can be connected to a retaining section of the contact leg.The release section can end at a free end of the clamping leg. The holding section and the release section can together have two opposing bends and together form a Z-shape, so that the holding section and a region of the release section having the release surface can run essentially parallel according to one possible design. The clamping point of the conductor connection terminal can be provided at an opening region of the conductor entry channel into a connection space of the conductor connection terminal. The release section of the clamping spring can be arranged in a blind-hole-like region of the connection space opposite the opening region. By integrating the holding section and the release section into the contact leg of the clamping spring, a release mechanism for the conductor connection terminal can be implemented efficiently and cost-effectively.

[0024] According to one embodiment, the actuating element can have an operating section with a push-button surface, a tool holder, and / or a handle. This can facilitate the operation of the actuating element. The operating section can be an area of ​​the actuating element that is accessible from the vicinity of the conductor connection terminal. Tool-based and / or manual operation of the actuating element can be enabled by means of the push-button surface, the tool holder, and / or the handle. A tool holder can, for example, be a groove shaped to fit a screwdriver tip.

[0025] According to one embodiment, the operating section can be immersed in the insulating housing depending on the open or closed position of the clamping leg or can be substantially flush with an outer surface of the insulating housing on its conductor entry side. This can enable or facilitate intuitive position-dependent operation of the actuating element, the operating element of which can be difficult to access in the open position intended for automatic displacement of the clamping leg due to the recessed position. This also makes it easy to visually derive the position of the clamping leg from the position of the operating section. In the open position of the clamping leg, the actuating element can in particular be completely recessed into the insulating housing.In other words, the operating section can be inserted into the insulating housing in such a way that an outer contour of the operating section is enclosed within an outer contour of the insulating housing. In principle, according to further embodiments, it is also conceivable for the operating section to protrude beyond the outer surface of the insulating housing.

[0026] According to one embodiment, the support section of the actuating element can have a convex surface. A convex surface is a surface that is curved outward. This allows the support section to roll, for example, on a straight support surface of the insulating housing during a pivoting movement, thus enabling a pivoting movement of the actuating element, for example, in an actuating channel, in a simple manner without having to adhere to tight tolerance limits.

[0027] According to a further development, a support surface of the insulating housing for supporting the support section of the actuating element can have a concave surface shaped to match the convex surface of the support section. A concave surface is a surface curved inward. This allows the support surface to form a predefined curved path for the support section, along which the support section can slide smoothly. This allows a very precise pivoting movement of the actuating element to be realized, which can be particularly advantageous for conductor connection terminals with an automatic conductor connection and a trigger mechanism that is often designed to be sensitive for this purpose.

[0028] According to one embodiment, the pivot bearing can be spaced from the second side of the actuating element by a pivot arm protruding from the second side of the actuating element. This allows for greater leverage with the actuating element and thus higher force transmission. The pivot arm and the pivot bearing can be formed integrally with the actuating element. The pivot arm can protrude from the second side of the actuating element between the operating section and the actuating section. The pivot arm can be guided at least in sections over the spring arch of the clamping spring. The pivot bearing can be arranged, for example, above the spring arch, i.e. facing an outer circumferential surface of the spring arch, or in a housing area of ​​the insulating housing facing the contact leg of the clamping spring.

[0029] According to one embodiment, the actuating section of the actuating element can comprise a metallic material. This can enable a robust and reliably effective actuating element. In this case, it can be provided that at least part of the actuating section is metallic. A metallic material can, for example, be an essentially pure metal or a metal alloy. A metallic material can, for example, be spring steel. Spring steels are characterized by high strength, but at the same time have sufficient elasticity to be able to compensate for point-like force peaks during actuation of the actuating element with elastic deformation. Furthermore, it is not excluded that the actuating section comprises other materials, for example a plastic material or a ceramic material. The metallic material can also be present in other sections of the actuating element.For example, the actuating element can have a metallic core that is surrounded by a sheathing material, for example, in the area of ​​the operating section or the support section, and is exposed in the actuating section. Alternatively, the metallic core can also be completely surrounded by a sheathing material, for example, a plastic material.

[0030] According to one embodiment, the support section, the operating section, and / or the pivot bearing can be made of a plastic material. This allows for the implementation of a lightweight, safe, and comfortable actuating element that is also cost-effective to manufacture. According to one possible embodiment, the entire actuating element can be made of a plastic material. According to another possible embodiment, the actuating element can have a core made of a metallic material and be encased, for example, overmolded, with a plastic material at least in the area of ​​the operating section or the support section.Alternatively, it is conceivable, for example, that the actuating element is designed as a composite actuating element with an operating section, support section and / or pivot bearing comprising a plastic material and an actuating section comprising a metallic material, which is connected thereto in particular in a non-detachable manner, for example by means of a material bond.

[0031] According to one embodiment, a support surface of the insulating housing for supporting the support section of the actuating element can form a stop for limiting the pivoting movement of the actuating element. The actuating element can be movable relative to the support surface, for example, pivotally movable in an actuating channel of the insulating housing. Thus, with a suitable shape of the actuating element, a channel wall of the actuating channel, which forms a support surface for supporting the support section, can limit a pivoting movement of the actuating element in the actuating channel. This can prevent excessive deflection of the actuating element and, accordingly, of the clamping leg of the clamping spring during a pivoting movement of the actuating element.

[0032] According to one embodiment, the insulating housing can have a clamping spring support on which the clamping spring is suspended. The clamping spring support has a stop surface to limit displacement of the clamping leg toward the contact leg. This prevents excessive deflection of the clamping leg and ensures a long service life of the actuating element and the clamping spring. Furthermore, the clamping spring can be better held in the insulating housing by the clamping spring support. The clamping spring support can have a curvature adapted to a radius of the spring arc in order to ensure optimal hold of the clamping spring on the clamping spring support.

[0033] In general, in the context of this application, the words “a / an”, unless expressly defined otherwise, are not to be understood as a number, but as an indefinite article with the literal meaning of “at least one”.

[0034] The invention permits various embodiments and is explained in more detail below using exemplary embodiments and the accompanying drawings. They show schematically: Fig. 1a-1b - a conductor connection terminal according to a first embodiment in a closed position and an open position in sectional side views; Fig. 1c-1d - the conductor connection terminal according to the first embodiment in a closed position and an open position in perspective sectioned side views; Fig. 2a-2b - a conductor connection terminal according to a second embodiment in a closed position and an open position in sectional side views; Fig. 2c-2d - the conductor connection terminal according to the second embodiment in a closed position and an open position in perspective sectional side views; Fig. 3a-3b - a conductor connection terminal according to a third embodiment in a closed position and an open position in sectional side views; Fig. 3c-3d - the conductor connection terminal according to the third embodiment in a closed position and an open position with an inserted electrical conductor in further sectional side views; and Fig. 3e-3f - the conductor connection terminal according to the third embodiment in a closed position and an open position with the insulating housing hidden in perspective side views.

[0035] The Fig. 1a to 1d, the Fig. 2a to 2d and the Fig. 3a to 3f show a conductor connection terminal 1 according to three different embodiments. As shown in the Fig. As can be seen in Figures 1a to 1d, 2a to 2d, and 3a to 3d, the conductor terminal 1 has an insulating housing 2, which can be made, for example, of a plastic material and protects the components of the conductor terminal 1 arranged in the insulating housing 2 from environmental influences and contact. The figures also show that the conductor terminal 1 has a busbar 3, a clamping spring 4, and an actuating element 5.

[0036] As in 1a to 1d, Fig. 2a to 2d and Fig. 3a to 3f, the clamping spring 4 according to the three presented embodiments has a contact leg 6 for supporting the clamping spring 4, a clamping leg 8 for clamping a, for example, in Fig. 3d and a spring arch 7 for deflecting the clamping spring 4, so that the contact leg 6 can be at least partially opposite the clamping leg 8. The clamping spring 4 is, as can be seen, for example, from the Fig. 1d, Fig. 2d and Fig. 3c, suspended from a clamping spring support 36, wherein the clamping spring support 36 has a stop surface 37 to limit a displacement of the clamping leg 8 in the direction of the contact leg 6. As a result, the hold of the clamping spring 4 in the insulating housing 2 as well as its service life can be improved by gentle deflection of the clamping leg 8. The clamping leg 8 forms with the busbar 3 a Fig. 1c, Fig. 2c and Fig. 3a shown terminal point 9 for a conductor terminal 1 insertable, for example in Fig. 3d shown electrical conductor 10. The clamping leg 8 is between a Fig. 1b, Fig. 1d, Fig. 2b, Fig. 2d, Fig. 3b, Fig. 3d and Fig. 3f shown open position O and one in the Fig. 1a, Fig. 1c, Fig. 2a, Fig. 2c, Fig. 3a, Fig. 3c and Fig. 3e shown closed position S for opening and closing the clamping point 9.

[0037] The conductor connection terminal 1 is designed for automatic displacement of the clamping leg 8 into the closed position S upon insertion of the electrical conductor 10 into the conductor connection terminal 1. For this purpose, the conductor connection terminal 1 has a release mechanism 22, for example on the busbar 3 or on the contact leg 6 of the clamping spring 4, as will be explained in more detail below with reference to the individual embodiments using the figures. The actuating element 5 is designed to displace the clamping leg 8 into the open position O. When the clamping leg 8 is displaced into its open position O, it can be displaced onto the contact leg 6. When displaced from the open position O to the closed position S, the actuating element 5, which rests at least partially against the clamping leg 8, can be automatically pivoted along.

[0038] The actuating element 5 is at least partially, according to one possible embodiment, substantially completely embedded in the insulating housing 2 and pivotably mounted therein. The actuating element 5 is designed to move the clamping leg 8 into the open position O by means of a Fig. 1b, Fig. 2b and Fig. 3b shown pivoting movement B of the actuating element 5. According to the three embodiments shown, the actuating element 5 is designed as a pivoting pushbutton, so that the actuating element 5 can be actuated by a pressure force introduced into the actuating element 5 from the outside. According to one possible embodiment, the actuating element 5 designed as a pivoting pushbutton is configured to be operable to move the clamping leg 8 into the open position O, while an automatic movement of the clamping leg 8 into the closed position S is associated with an automatic movement of the pivoting pushbutton. The pivoting mobility of the actuating element 5 is associated with a lever effect, by means of which a return of the clamping leg 8 to the open position O is possible with little effort.

[0039] The actuating element 5 has a support section 11 on a first side 5a of the actuating element 5 for support on the insulating housing 2. The support section 11 can, for example, have a flat surface according to the first embodiment or a curved surface, as for example according to the second and third embodiments. A support surface 34 of the insulating housing for supporting the support section 11 of the actuating element can also, as can be seen, for example, from the Fig. 1a and Fig. 1b and 3a and 3b, form a stop to limit the pivoting movement B of the actuating element 5.

[0040] On a second side 5b of the actuating element 5 opposite the first side 5a, the actuating element 5 has a pivot bearing 12 and an actuating section 13 for contact with the clamping leg 8 of the clamping spring 4. A compact arrangement of pivot bearing 12 and actuating section 13 on one side and an opposing support of the actuating element 5 on the other side of the actuating element 5 on the insulating housing 2 enables an effective and powerful displacement of the clamping leg 8 with high operating comfort and low installation space requirements. The actuating section 13 rests at least partially against the clamping leg 8, wherein the contact surface can be configured, for example, based on the Fig. 1a, Fig. 1b or based on the Fig. 3c, Fig. 3d can be seen during a displacement of the clamping leg 8 into the open position O, so that the actuating section 13 increasingly rests against the clamping leg 8. During the displacement of the clamping leg 8 into the open position O, a compressive force is exerted on the clamping leg 8 by the actuating section 13. The support section 11, the actuating section 13 and the pivot bearing 12 can, as shown in the figures, be formed integrally with the actuating element 5, which can, for example, be made of a plastic material. In principle, it is also conceivable for the actuating section 13 to comprise a metallic material according to one possible embodiment. The support section 11, the pivot bearing 12 and / or an operating section 30, which will be explained below, can comprise a plastic material.

[0041] For example, in the Fig. 1a, Fig. 2a and Fig. As shown in Figure 3d, the pivot bearing 12 of the actuating element 5 is arranged between the spring arc 7 of the clamping spring 4 and a conductor entry side 14 of the insulating housing 14, thus enabling a compact arrangement with favorable pivot angles of the actuating element 5. The conductor entry side 14 describes a housing side of the insulating housing 2, at which the electrical conductor 10 can be inserted into the conductor connection terminal 1.

[0042] The following is based on the Fig. 1a to 1d, the first embodiment of the conductor connection terminal 1 is explained in more detail. As in Fig. As can be seen in Figure 1c, the first side 5a of the actuating element 5 is spaced from the second side 5b by a distance A that is greater than the spring arc width F of the spring arc 7 of the clamping spring 4. This results in a comparatively solid and robust actuating element 5 that can absorb even high forces during an automatic displacement of the clamping leg 8 into the closed position. The spring arc width F describes a measure of the spacing of the two spring legs of the clamping spring 4 from one another, particularly at their transition into the spring arc 7.

[0043] For example, the Fig. 1c, the pivot bearing 12 is arranged starting from a vertex 7a of the spring arch 7 in a housing area of ​​the insulating housing 2 facing the clamping leg 8. As a result, a reliable displacement of the clamping leg 8 can be achieved even with small pivot angles of the actuating element 5. As shown in Fig. 1c, the pivot bearing 12 is arranged closer to the clamping leg 8 than to the contact leg 6 of the clamping spring in the insulating housing 2. As further shown in the Fig. As shown in Figures 1a to 1d, the pivot bearing 12 of the actuating element 5 is designed as a pivot pin 16 with a cylindrical basic shape, received in a bearing recess 15 of the insulating housing 2. The bearing recess 15 is a corresponding cavity in the insulating housing 2 for receiving the pivot pin 16. This enables a structurally simple and defined pivotable mounting of the actuating element 5.

[0044] As in the Fig. 1c and Fig. 1d, the actuating element 5 has a conductor insertion channel 19 through which the electrical conductor 10 can be inserted into the conductor connection terminal 1. This implements an actuating element 5 with an integrated conductor insertion, resulting in a compact conductor connection terminal 1. The actuating element 5 can also be pivoted when an electrical conductor 10 is inserted and clamped into the conductor insertion channel 19. For this purpose, the electrical conductor 10 can be accommodated in the conductor insertion channel 19 with sufficient play by a sufficiently large clear width of the conductor insertion channel 19. Fig. 1a to 1d further show that the actuating element 5 has an operating portion 30 with a handle 32, so that an easily operable actuating element 5 is provided.

[0045] Like the Fig. 1c and Fig. 1d, the busbar 3 has a release mechanism 22 with a retaining tab 23 for holding the clamping leg 8 in its open position O and with a release surface 24 for releasing the clamping leg 8 when the release surface 24 is touched by the inserted electrical conductor 10. As a result, the clamping leg 8 can be temporarily secured to the retaining tab 23 until an inserted electrical conductor 10 activates the release surface 24 of the release mechanism 22. The release surface 24 can, as shown, be a side frame of the busbar 3 extending from the clamping point 9 in the direction of the contact leg 6, which side frame can be displaced laterally by an inserted electrical conductor 10, so that the retaining tab 23 arranged on the release surface 24 comes out of engagement with the clamping leg 8 when activated and the clamping leg 8 is displaced into its closed position S due to spring force.The trigger mechanism 22 is designed as a frame which is separate from the busbar 3 and which is fixed to the busbar.

[0046] The following is based on the Fig. 2a to 2d, the second embodiment of the conductor connection terminal 1 is explained in more detail. For example, Fig. As can be seen from Figure 2c, the pivot bearing 12 is arranged, starting from an apex 7a of the spring arch 7, in a housing area of ​​the insulating housing 2 facing away from the clamping leg 8. Accordingly, the pivot bearing 12 is arranged closer to the contact leg 6 than to the clamping leg 8 of the clamping spring 4 in the insulating housing 2. This allows for increased leverage and force transmission.

[0047] As in the Fig. 2a to 2d, the pivot bearing 12 of the actuating element 5 is designed as a pivot pin 16 with a cylindrical basic shape, received in a bearing recess 15 of the insulating housing 2. The bearing recess 15 is a corresponding cavity in the insulating housing 2 for receiving the pivot pin 16. This enables a structurally simple and defined pivotable mounting of the actuating element 5. In addition, the pivot bearing 12 is spaced from the second side 5b of the actuating element 5 by a pivot arm 35 protruding from the second side 5b of the actuating element 5, so that an improved leverage effect is achieved. The pivot arm 35 and the pivot bearing 12 are, as shown, formed integrally with the actuating element 5 according to the embodiment shown. The pivot arm 35 is guided over the spring arch 7 of the clamping spring 4 and the pivot bearing 12 faces an outer peripheral surface of the spring arch 7.

[0048] As further stated in the Fig. As shown in Figures 2a to 2d, the insulating housing 2 has a conductor insertion channel 20 for inserting the electrical conductor 10 into the conductor connection terminal 1 and an actuating channel 21 extending substantially parallel to the conductor insertion channel 20 for receiving the actuating element 5. As a result, the functions of conductor insertion and actuation of the clamping leg 8 by the actuating element 5 are structurally separated from one another, with the parallel alignment resulting in comparatively low installation space requirements. The actuating element 5 is movably arranged in the actuating channel 21 and can be displaced along the actuating channel 21. Fig. 2a to 2d show that the actuating channel 21 has a shape that is, at least in sections, adapted to the outer contour of the actuating element 5. As shown, the support section 11 of the actuating element 5 has a convex surface. To match this, a support surface 34 of the insulating housing 2 for supporting the support section 11 of the actuating element 5 has a concave surface shaped to match the convex surface of the support section 11. This creates a defined curved path for the support section 11, along which the support section 11 can slide smoothly, resulting in a very precise pivoting movement B of the actuating element 5.

[0049] Like the Fig. 2c and Fig. 2d, the busbar 3 has a release mechanism 22 with a retaining tab 23 for holding the clamping leg 8 in its open position O and with a release surface 24 for releasing the clamping leg 8 when the release surface 24 is touched by the inserted electrical conductor 10. As a result, the clamping leg 8 can be temporarily secured to the retaining tab 23 until an inserted electrical conductor 10 activates the release surface 24 of the release mechanism 22. The release surface 24 can, as shown, be a side frame of the busbar 3 extending from the clamping point 9 in the direction of the contact leg 6, which side frame can be displaced laterally by an inserted electrical conductor 10, so that the retaining tab 23 arranged on the release surface 24 comes out of engagement with the clamping leg 8 when activated and the clamping leg 8 is displaced into its closed position S due to spring force.

[0050] In the Fig. 2a to 2d further show that the actuating element 5 has an operating section 30 with a tool holder 31 designed as a groove, so that an easily operable actuating element 5 is provided. Fig. 2c and Fig. 2d also shows that the operating section 30 dips into the insulating housing 2 depending on the open position O or closed position S of the clamping leg 8, as shown in Fig. 2d for the open position O, or essentially flush with an outer surface 33 of the insulating housing 2 on its conductor entry side 14, as shown in Fig. 2c for the closed position S. This enables intuitive position-dependent operation of the actuating element 5 and enables optical detection of a position of the clamping leg 8 that can be derived from the position of the actuating element 5.

[0051] The following is based on the Fig. 3a to 3f, the third embodiment of the conductor connection terminal 1 is explained in more detail. As in Fig. 3a, the first side 5a of the actuating element 5 is spaced from the second side 5b by a distance A that is greater than a spring arc width F of the spring arc 7 of the clamping spring 4. In addition, the distance A is greater than half the channel width K of the conductor entry channel 20. This results in a comparatively solid and robust actuating element 5 that can also absorb high forces during an automatic displacement of the clamping leg 8 into the closed position. For example, Fig. As can be seen from Figure 3a, the pivot bearing 12 is arranged, starting from a vertex 7a of the spring arch 7, in a housing area of ​​the insulating housing 2 facing away from the clamping leg 8. Accordingly, the pivot bearing 12 is arranged closer to the contact leg 6 than to the clamping leg 8 of the clamping spring 4 in the insulating housing 2. This allows for increased leverage and force transmission.

[0052] As in the Fig. 3a to 3d, the pivot bearing 12 of the actuating element 5 is designed as a support section 18 of the actuating element 5 resting on a bearing projection 17 of the insulating housing 2. This achieves a structurally simple and defined pivotable mounting of the actuating element 5 in the insulating housing 2. The bearing projection 17 can be designed as shown in the Fig. 3a to 3d, have a convex surface, while the support section 18 has a concave surface shaped to match this. In principle, according to an alternative embodiment, it is also conceivable for the support section 18 of the actuating element 5 to rest on the spring arch 7 of the clamping spring 4, with the contour of the support section 18 being adapted accordingly to the spring arch 7.

[0053] As further stated in the Fig. 3a and Fig. 3b, the insulating housing 2 has a conductor insertion channel 20 for inserting the electrical conductor 10 into the conductor connection terminal 1 and an actuating channel 21 extending substantially parallel to the conductor insertion channel 20 for receiving the actuating element 5. As a result, the functions of conductor insertion and the actuation of the clamping leg 8 by the actuating element 5 are structurally separated from one another, wherein the parallel alignment results in a comparatively low installation space requirement. The actuating channel 21 can, at least in sections, have a cross-section at least half as large as the conductor insertion channel 20 and can be completely filled by the actuating element 5 across its width, at least in sections, so that a comparatively solid actuating element 5 is present. As shown, for example, in the Fig. 3a and Fig. As shown in Figure 3b, the support section 11 of the actuating element 5 has a convex surface that interacts with a comparatively straight support surface 34 of the actuating channel 21. This allows the support section 11 to roll on the support surface 34 during a pivoting movement B, so that the pivoting movement B of the actuating element 5 in the actuating channel 21 is easily enabled without the need to maintain tight tolerance limits.

[0054] In the Fig. 3a to 3f further show that the contact leg 6 of the clamping spring 4 has a release mechanism 22 with a holding section 25 for holding the clamping leg 8 in its open position O and with a release section 26 for releasing the clamping leg 8 when the electrical conductor 10 strikes the release section 26. As a result, the clamping leg 8 can be temporarily secured in its open position O to the contact leg 6 of the clamping spring 4 until an electrical conductor 10 inserted into the conductor connection terminal 1 triggers an automatic displacement of the clamping leg 8 into the closed position S. The holding section 25 has a holding projection 28 to which the clamping leg 8 can be secured with its free end, as shown. As shown, the holding section 25 extends at a bend from a contact section 27 of the contact leg 6, which is provided for supporting the contact leg 6 in the insulating housing 2.The release section 26 has a release surface 24 that extends perpendicular to a direction of insertion of the electrical conductor 10 into the conductor connection terminal 1. An impact of the conductor 10 on the release surface 24 can occur, as shown in FIG. Fig. 3d, lead to a displacement of the release section 26, which in turn causes a displacement of the holding section 25 and a related release of the clamping leg 8 from engagement with the holding projection 28. As shown, the holding section 25 and the release section 26 can have two opposing bends and describe a Z-shape, wherein the holding section 25 and a region of the release section 26 having the release surface 24 can run essentially parallel to one another. By integrating the holding section 25 and the release section 26 into the contact leg 6 of the clamping spring 4, a release mechanism 22 of the conductor connection terminal 1 for automatically displacing the clamping leg 8 into the closed position S can be realized in an efficient and cost-effective manner.

[0055] In the Fig. 3d to 3f further show that the actuating element 5 has an operating section 30 with a tool holder 31 designed as a groove, so that an easily operable actuating element 5 is provided. Fig. 3c and Fig. 3d it is also evident that the operating section 30 dips into the insulating housing 2 depending on the open position O or closed position S of the clamping leg 8, as shown in Fig. 3d for the open position O, or essentially flush with an outer surface 33 of the insulating housing 2 on its conductor entry side 14, as shown in Fig. 3c for the closed position S. This enables intuitive position-dependent operation of the actuating element 5 and enables optical detection of a position of the clamping leg 8 that can be derived from the position of the actuating element 5.

[0056] By means of the above-described and exemplary embodiments in the Fig. 1a to 1d, 2a to 2d and 3a to 3f, a conductor connection terminal 1 with an automatic conductor connection can be provided, the actuating element 5 of which is designed to move the clamping leg 8 into its open position O for optimized force transmission and, at the same time, convenient operation.
