Description

[0001] The invention relates to a conductor terminal with an insulating housing, wherein the conductor terminal is designed as a multi-pole conductor terminal with several spring-loaded terminals arranged in the insulating housing, wherein the insulating housing has a conductor insertion opening assigned to a spring-loaded terminal, through which an electrical conductor can be inserted into the insulating housing in a conductor insertion direction and clamped to the assigned spring-loaded terminal by means of spring force, wherein a spring-loaded terminal has at least one busbar and a clamping spring, which has a clamping leg with a clamping edge for clamping an electrical conductor to a clamping point on a contact section of the busbar, wherein the conductor terminal has at least one actuating element,by which the clamping leg can be moved into an open position upon manual actuation of a manual actuation section of the actuating element.

[0002] Such a conductor terminal is known from DE 10 2020 119 372 A1. It is a conductor terminal with 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 an open position, thereby clamping the electrical conductor.

[0003] Based on this, it is the object of the present invention to provide a further improved conductor connection terminal.

[0004] This object is achieved by arranging the at least one actuating element between two adjacent conductor entry openings. This allows the actuating element to be integrated into the conductor terminal in a very space-saving manner. This allows existing and proven conductor terminal designs, which were previously designed without an actuating element, to be developed into a conductor terminal with an actuating element for actuating the clamping leg with little effort and without a completely new design.

[0005] The invention is suitable, for example, for compact junction box terminals, e.g. those with a leaf spring connection, in which the clamping leg is connected to a support section of the clamping spring without a spring bend which is known in many conductor connection terminals and which extends over an angular range of more than 180°.

[0006] According to an advantageous embodiment of the invention, the at least one actuating element is designed as a pivotable lever, by means of which the clamping leg can be moved into the open position by means of a pivoting movement, or as a displaceable push-button, by means of which the clamping leg can be moved into the open position by means of a sliding movement. This enables a wide range of possible implementations and integration options for the actuating element into an existing conductor connection terminal construction. If the conductor connection terminal has several actuating elements, these can be uniformly designed as pivotable levers or displaceable push-buttons. It is also possible for the actuating elements to be designed differently, e.g., partly as levers and partly as push-buttons.

[0007] The insulating housing can have a partition made of the same material as the insulating housing between two adjacent conductor entry openings. The partition can extend into the interior of the insulating housing up to the spring-loaded terminals to separate them from each other, ensuring that an electrical conductor inserted through a conductor entry opening can only be connected to the spring-loaded terminal associated with that conductor entry opening. If such a partition is present, the actuating element can extend parallel to this partition. For example, the actuating element can be arranged directly on the partition or rest against the partition.

[0008] According to an advantageous embodiment of the invention, the at least one actuating element arranged between the adjacent conductor entry openings simultaneously forms a partition between the adjacent conductor entry openings. In this way, space savings can be further optimized, since the previously explained partition of the insulating housing can be completely or at least partially omitted. The partition is then replaced by the actuating element arranged between the adjacent conductor entry openings. The actuating element can be formed from an insulating material, e.g., the same material as the insulating housing or a different material, in particular a plastic material.

[0009] According to an advantageous embodiment of the invention, it is provided that exactly one clamping spring can be actuated by the at least one actuating element or that a plurality of clamping springs, in particular two adjacent clamping springs, can be actuated by the at least one actuating element. The actuating element is advantageously arranged between two adjacent clamping springs. This also enables a multitude of implementation options for the conductor connection terminal. If an actuating element is designed to actuate a plurality of clamping springs, fewer actuating elements are required in the conductor connection terminal, so that the space required for this can be further reduced. In this case, the insulating housing can have, for example, a partition wall between adjacent conductor entry openings between which no actuating element is arranged.

[0010] According to an advantageous embodiment of the invention, the at least one actuating element is manually operable at its manual actuating section on a side of the insulating housing at which the electrical conductor can be inserted into the respective conductor insertion opening. Accordingly, the actuating element is advantageously manually operable at the conductor insertion side of the insulating housing. If electrical conductors are already clamped to the terminal points, manual actuation of the actuating element is hindered by the parts of the electrical conductors protruding from the insulating housing, thereby reducing the likelihood of incorrect operation of the actuating element.

[0011] According to an advantageous embodiment of the invention, the manual actuation section is located between adjacent connected electrical conductors when electrical conductors are connected in the conductor connection terminal. This also reduces the likelihood of incorrect actuation of the manual actuation element.

[0012] According to an advantageous embodiment of the invention, the conductor connection terminal has a retaining element configured to hold the clamping leg in the open position. The retaining element allows the clamping leg to be held in the open position even when no manual actuation force is exerted on the actuation element. Such a design allows the integration of automatic release technology into spring-loaded terminals and conductor connection terminals of various designs. In particular, proven conductor connection terminals of known design can be upgraded with little effort to include automatic release functionality, i.e., with automatic conductor connection of the electrical conductor to be clamped.

[0013] The holding element can be arranged so as to be movable, e.g. displaceable, pivotable or deflectable in some other way, so that it can be slightly deflected by the inserted conductor in order to bring about the desired release effect of the clamping leg from the holding element. The holding element can, for example, be mounted so as to be displaceable, e.g. displaceable in a linear direction or an arcuate direction. The holding element can be mounted so as to be pivotable. In this case, the holding element can be pivoted about a fixed or variable pivot axis. In the case of a variable pivot axis, the holding element can, for example, be mounted so as to be floating and pivotable. The holding element can also be mounted so as to be movable in some other way so that it can be deflected sufficiently far to release the locking of the clamping leg on the holding element.

[0014] The actuating element allows the clamping leg to be moved into the open position when manually actuated, counter to the spring force of the clamping spring. The clamping leg can then be held in this open position by the retaining element, particularly without further manual actuation of the actuating mechanism, allowing the electrical conductor to be inserted at any time without any particular effort. For example, the clamping leg can be locked to the retaining element in the open position.

[0015] The clamping leg, together with the contact section of the busbar, can form a clamping point for clamping an electrical conductor between the clamping leg and the contact section. In the open position, at least the clamping edge of the clamping leg is pivoted away from the contact section of the busbar. The clamping leg can be pivoted, for example, between an open position, in which the electrical conductor is freely movable between the clamping leg and the contact section, and a clamping position, in which the clamping leg clamps the electrical conductor to the contact section.

[0016] The retaining element can, for example, act directly on the clamping leg to hold it in the open position. For example, a first locking element can be arranged on the clamping leg and a second locking element on the retaining element, with the first and second locking elements being able to be locked together in the open position. The first locking element can be designed as a locking projection or locking hook. The second locking element can be designed as a locking edge or locking opening.

[0017] The retaining element can be provided as a separate component, for example, attached to an insulating housing of a conductor terminal, to the busbar, or to another component. The retaining element can also be formed integrally with the clamping spring.

[0018] According to an advantageous embodiment of the invention, the retaining element is arranged behind the clamping point or behind the majority of the busbar in the conductor insertion direction of the electrical conductor into the spring-loaded terminal connection. In this way, the retaining element does not impede the insertion of the electrical conductor. For example, in the open position, i.e., when the clamping leg is locked to the retaining element, the retaining element may not protrude into a conductor receiving space, or may protrude only slightly relative to the clamping leg, when viewed in the conductor insertion direction.

[0019] According to an advantageous embodiment of the invention, the spring-loaded terminal connection has a release element, the actuation of which allows the holding element to be deflected to such an extent that the clamping leg held on the holding element is released from the holding element. The release element can have a release section. The clamping leg held on the holding element in the open position can be released from the holding element by the release element when an electrical conductor to be clamped exerts an actuating force on the release section. This allows the clamping leg to be automatically released from the holding element when the electrical conductor is inserted. The release section can be subjected to pressure by a separate tool, a component of the conductor connection terminal, such as an actuating element, or directly via the inserted electrical conductor itself, thereby causing the clamping leg to be released from the holding element.By means of the release element, the clamping leg, which is held in the open position on the retaining element, can be released from the retaining element by applying pressure to the release section in the conductor insertion direction (L) of the electrical conductor to be connected. Depending on the design of the spring-loaded terminal connection, the release element can be formed as part of the clamping spring, e.g., as a release element formed integrally with the clamping spring, or as a separate component.

[0020] According to an advantageous embodiment of the invention, the release element is part of the component or assembly of the spring-loaded terminal connection that has the retaining element. This allows the design and assembly effort for the spring-loaded terminal connection to be kept to a minimum. In particular, only one component or assembly needs to be assembled to assemble the release element and the retaining element, rather than two different components or assemblies. For example, the release element can be formed integrally with the retaining element. The component or assembly can be made of plastic or metal, for example, or a combination of such materials.

[0021] According to an advantageous embodiment of the invention, the clamping spring has a support section designed to support the clamping spring on the busbar. This support section allows for secure support of the clamping spring and sufficient support against the spring force exerted by the clamping leg.

[0022] According to an advantageous embodiment of the invention, the support section has a base section and a fastening section, wherein the clamping leg branches off from the base section and the support section engages behind the busbar with its fastening section, so that the busbar rests on the fastening section and is at least partially arranged between the base section and the fastening section. In this case, the clamping leg can branch off from the base section, in particular without a 180° spring bend. For example, the clamping leg can branch off from the base section at an acute angle, which can be less than 60°, for example, in the open position. The base section can be connected to the fastening section via a connecting section.For example, the base portion may be substantially parallel to the attachment portion or at a slight angle thereto, in particular an angle of less than 20°.

[0023] According to an advantageous embodiment of the invention, a conductor guide channel for guiding the electrical conductor to be clamped to the contact section can be formed in the insulating material housing, wherein the release section of the release element is arranged in the conductor guide channel or at least projects into the conductor guide channel or at least is arranged in extension of the conductor introduction channel.

[0024] According to an advantageous embodiment of the invention, the release section of the release element can be arranged behind the contact section or at least behind the clamping point in the conductor insertion direction.

[0025] For the purposes of the present invention, the indefinite term "a" is not to be understood as a numerical term. Therefore, if, for example, a component is mentioned, this is to be interpreted as "at least one component." Angles expressed in degrees refer to a circle of 360 degrees (360°).

[0026] The invention is explained in more detail below using exemplary embodiments and drawings.

[0028] The Fig. 1 and Fig. 2 shows a conductor connection terminal 1 having an insulating housing 2. The insulating housing 2 has a conductor insertion opening 20 on a conductor insertion side, through which an electrical conductor can be inserted into the insulating housing 1 in a conductor insertion direction L and clamped to a spring-loaded terminal connection.

[0029] Visible is a spring-loaded terminal connection arranged in the insulating housing 2, which has a clamping spring 4 and a busbar 3. The clamping spring 4 has a support section 41, via which the clamping spring 4 is supported on the busbar 3. The clamping spring 4 also has a clamping leg 43 branching off from the support section 41 at an acute angle. The clamping leg 43 extends to a free end, at which the clamping leg 43 has a Fig. 2 has a clamping edge 46 for clamping the electrical conductor. Fig. In the clamping position shown in Figure 1, the clamping leg 43 rests with the clamping edge 46 against a contact section 31 of the busbar 3 when no electrical conductor is inserted. An electrical conductor can be clamped between the clamping leg 43 or the clamping edge 46 and the contact section 31 at a clamping point 30.

[0030] The support section 41 extends from a base section 40, from which the clamping leg 43 branches off, to a connecting section 42 arranged at an angle thereto. The connecting section 42 merges into a fastening section 44 arranged at an angle to the connecting section 42. The fastening section 44 engages behind the busbar 3, ie it rests on the back of the busbar 3 on a side facing away from the clamping point 30.

[0031] The conductor connection terminal 1 further has a holding element 5, by means of which the clamping leg 43 can be held in the open position. The holding element 5 has a locking element 50, which can lock into the open position with a locking element designed as a counterpart on the clamping leg 43. The clamping leg 43 cannot then easily move back into the clamped position. The locking element formed on the clamping leg 43 can, for example, be formed by the clamping edge 46, as illustrated in the figures. However, at least one separate locking element can also be formed on the clamping leg 43, e.g. in the form of a protruding locking tab, which can then be locked into the locking element 50.

[0032] To actuate the clamping leg 43 or to actuate several such clamping legs 43, e.g. second adjacent clamping leg 43, the conductor connection terminal 1 has an actuating element 6, which is arranged in the Fig. 1 to 6 is designed as a pivotable actuating lever. The actuating element 6 has a manual actuating section 60, at which the actuating element 6 can be manually actuated by a user, ie a pivoting movement of the actuating element 6 can be carried out. For this purpose, the actuating element 6 is mounted on a bearing point 61 in the insulating housing 2. The actuating element 6 can be pivoted about the bearing point 61, as a comparison of the Fig. 1 and Fig. 3 shows.

[0033] The actuating element 6 extends with an actuating section 62 into the insulating housing 2 up to the clamping leg 43. The Fig. 1 and show the clamping leg 43 which has not yet been deflected by the actuating element 6 and is in the clamping position in which the free end of the clamping leg can, for example, rest on the contact section 31 of the busbar 3. In Fig. 3, the manual actuating element 6 was pivoted. As a result, the actuating section 62 pivots the clamping leg 43 away from the contact section 31 until it is locked with its clamping edge 46 or another locking element to the locking element 50 of the holding element 5 and is thereby held in the open position.

[0034] The Fig. Figure 4 shows the conductor terminal 1 in a perspective view of the conductor insertion side of the insulating housing 2, where two conductor insertion openings 20 are provided. In this case, the conductor terminal 1 is thus designed as a two-pole conductor terminal, but can also be designed analogously as a multi-pole conductor terminal with more than two spring-loaded terminals. It can be seen that the actuating element 6 is located between the conductor insertion openings 20, in particular at a location where, in known conductor terminals, a partition wall of the insulating housing 2 is formed between the conductor insertion openings 20.This partition wall can be omitted in the embodiment shown, since it can be replaced at least in large part by the actuating element 6, in particular the manual actuating section 60 and / or the part adjoining the manual actuating section 60 in the insulating material housing.

[0035] The Fig. 5 shows an advantageous design of the actuating element 6 designed as a pivotable actuating lever. Since the actuating element 6 is designed to actuate two adjacent clamping legs, the actuating section 62 can extend in the width direction beyond the otherwise relatively narrow design of the actuating element 6, so that the actuating element 6 can be designed in the shape of a hammer.

[0036] Based on the Fig. Figure 6 illustrates how a release element 8 can be integrated into the conductor connection terminal 1. The release element 8 serves to release the locking of the clamping leg 43 on the holding element 5. The release element 8 has a release section 80 that can be actuated by the inserted electrical conductor. If an electrical conductor exerts a compressive force on the release section 80, the holding element 5 with the locking element 50 is displaced slightly toward a rear housing wall 21 of the insulating housing 2 until the clamping leg 43 can be released from the locking element 50. The clamping leg 43 then springs out until it rests against the inserted electrical conductor and presses it against the contact section 31.

[0037] The release element 8 can act mechanically on the holding element 5 with a transmission section 81 when the release section 80 is actuated. As a result, the holding element 5, which can be rotatably suspended on a pivot bearing 55, can be slightly rotated, whereby the locking between the locking element 50 and the clamping edge 46 can be released. The pivot bearing 55 can, for example, be designed as a pin 47 projecting from the connecting section 42, as shown in the Fig. 11, which engages in an opening 56 on the holding element 5. The release element 8 can be designed, for example, in the manner of a rocker, which can be pivoted upon actuation on the release section 80.

[0038] The Fig. Figures 7 to 11 show an embodiment of a conductor terminal 1 with an actuating element 6 arranged between two adjacent conductor insertion openings 20, which is designed as a displaceable push-button. The actuating element 6, in turn, has a manual actuating section 60, which can be actuated by the user by applying pressure from the conductor insertion side. As a result of this pressure, the actuating element 6 is displaced further into the insulating housing 2, as shown in Fig. 8. Through this displacement movement, the actuating element 6 moves the clamping leg 43 by means of its actuating section 62 from the Fig. 7 shown clamping position into the Fig. 8, in which the clamping leg 43 is spaced apart from the contact section 31 by its clamping edge 46. In the open position, the clamping leg 43 can again latch onto the locking element 50 by means of its clamping edge 46.

[0039] The Fig. 9 shows the conductor connection terminal 1 in a similar way to the Fig. 4, but here with the actuating element 6 designed as a sliding push button.

[0040] As the Fig. 10, the actuating element 6 in the region of the actuating section 62 can also, like the actuating element according to the Fig. 1 to 6, be hammer-shaped to deflect two adjacent clamping legs.

[0041] The Fig. 11 shows, similar to the Fig. 6, the conductor terminal 1 with the release element 8, which is designed and functions in a similar way as shown in the Fig. 6 was explained.

[0042] The Fig. Figure 12 shows, by way of example, a clamping spring 4 in which two clamping legs 43 are realized in a one-piece structural unit. The clamping spring 4 is thus suitable for two spring-loaded terminal connections arranged side by side. The clamping spring 4 can be used with all of the conductor connection terminals described above. The various sections of the support section 41 can be seen, i.e., the base section 40, the connecting section 42, and the fastening section 44. Also visible on the connecting section 42 are integrally formed pins 47, e.g., in the form of pins, which serve to receive and support the retaining element 5, as will be explained below.

[0043] The Fig. 13 shows a busbar 3 which offers two adjacently arranged receiving locations for electrical conductors on its contact section 31 and is accordingly suitable for the Fig. The clamping spring 4 shown in Figure 12 is suitable for implementing two adjacently arranged spring-loaded terminal connections. Brackets 34 for holding a retaining element 5 can be formed on the busbar 3.

[0044] The Fig. Figure 14 shows a combined holding-release element 5, 8 that can be used as an alternative to the previously described conductor connection terminals 1. In contrast to embodiments in which the holding element 5 and the release element 8 are separate components, here the holding element 5 and the release element 8 are formed into a single-piece unit, for example, from sheet metal in the form of a stamped and bent part.

[0045] The holding-release element 5, 8 has a holding element 5 that has two spaced-apart side cheeks 57 that extend parallel to each other. An opening 56 is arranged in each side cheek 57, into which a respective pin 47 of the connecting section 42 can be inserted to form the pivot bearing 55. A locking element 50 is formed on the free end of each side cheek 57. On the other side, the side cheeks 57 are connected to the release element 8 via lower longitudinal sections 53.

[0046] When force is applied to the release section 80 by the electrical conductor 9, the entire holding-release element 5, 8 is pivoted around the pivot bearing 55. As a result, the locking elements 50 are displaced slightly rearward in the conductor insertion direction L, allowing the clamping leg 43 to be released.

[0047] The Fig. Figure 15 shows another embodiment of a combined holding-release element 5, 8, which can also be used as an alternative to the previously described conductor connection terminals 1. The holding-release element 5, 8 has a holding element 5, which is formed with the aforementioned locking element 50 at the free end.

[0048] The area of ​​the holding element 5 formed with the locking element 50 has positive connecting elements 51 that can be inserted into the receiving elements 47 of the support section 41. This allows the locking element 50 to be supported on the support section 41, in particular on the connecting section 42, against the spring force exerted by the clamping leg 43 in the open position. The holding element 5 merges via upper longitudinal sections 52 into the release element 8, on which the release section 80 is arranged. The release section 80 is connected on its opposite side via lower longitudinal sections 53 to a fastening section 54 of the holding-release element 5, 8, which can be hooked into one of the holders 34 on the busbar 3. This fixes the entire holding-release element 5, 8 to the busbar 3.

[0049] When force is applied to the release section 80 by the electrical conductor 9, the lower region of the holding-release element 5, 8, which is attached to the bracket 34 via the fastening section 54, is fixed and cannot be deflected. Accordingly, only the upper region of the holding-release element 5, 8 with the locking element 50 is deflected by the inserted electrical conductor 9 and the release section 80.

[0050] One can see in the Fig.15 also states that the combined holding-release element 5, 8 may not be formed as a continuous sheet metal part in the region of the upper longitudinal sections 52, but may have a first recess 58 between the upper longitudinal sections 52. Similarly, the combined holding-release element 5, 8 may not be formed as a continuous sheet metal part in the region of the lower longitudinal sections 53, but may have a second recess 59 between the lower longitudinal sections 53. The first and / or second recess 58, 59 can increase the elasticity of the holding-release element 5, 8, whereby the required release forces that must be applied to the release section 80 by the inserted electrical conductor 9 can be reduced.A further advantage of the first and / or second recess 58, 59 is that a viewing window is provided through which it can be visually checked whether the electrical conductor 9 has been inserted sufficiently far into the insulating housing 2, at least if a transparent housing material is used in this area.
