Description

The invention relates to a conductor connection clamp for connecting electrical conductors to a conductor rail. The conductor terminal has an insulating housing with a housing base and a housing cover that can be connected to the housing base. The housing base has a conductor insertion opening which opens into a conductor connection space in the housing base. At least two clamping points are formed in the conductor connection space, at which electrical conductors inserted into the conductor insertion opening can be clamped to the busbar.

Such conductor connection terminals are already known.

DE 10 2015 105 757 A1 describes a spring clip with a connection spring element for clamping a conductor to a current bar. The connection spring element has two clamping springs, so it is designed as a double spring. In one piece with the double spring, the connecting spring element has an intermediate wall leg, which is a material tab bent out of the connecting spring element and forms a partition between the two clamping springs.

The U.S. 2014/127932 A1 shows a connection terminal with a housing in whose conductor connection space a spring seat is arranged separately, which at the same time forms the partition for two clamping springs arranged next to one another on the spring seat. After inserting the spring mount equipped with the clamping springs, the housing can optionally be closed with a housing cover.

The U.S. 2008/248699 A1 describes a terminal with an actuator that is inserted into an opening of the housing and conductor entry openings having. By depressing the actuating element, two opposite clamping points are opened. The actuator includes an integral divider for the two ports and a back wall separating the dual port from another dual port.

The U.S. 2018/277968 A1 discloses a connection device for electrical conductors with a housing, the housing having free spaces into which a spring carrier can be inserted. The spring carrier can be equipped with clamping springs and clamping cages that form clamping points for electrical conductors to be clamped. The terminal cages are placed on a busbar.

Proceeding from this, it is the object of the present invention to provide an improved conductor connection terminal.

The task is solved by the ladder clamp according to claim 1. In this conductor clamp, the projection formed on the housing cover, which protrudes into the conductor connection space when the housing cover is connected to the housing body, forms a partition between two clamping points.

This prevents, in a particularly simple manner, that conductors that have been inserted are routed past the clamping point provided for them or come into contact with the clamping point of another conductor. The formed partition ensures a defined and reliable guidance of the conductors to be connected. The improved guidance is also ensured when conductors are inserted at greater angles and not parallel to the walls of conductor entry openings. By forming the projection, which forms the partition, on the housing cover and thus on the insulating housing, the manufacture and assembly of the conductor terminal is simplified. Fewer manufacturing and assembly steps are required. Fewer individual parts to be assembled are required than with conventional conductor connection terminals. Manufacturing and assembly costs are significantly reduced. The conductor connection point does not require busbars or clamping springs specially formed with partitions, but can be equipped with simple and therefore inexpensive busbars and clamp springs.

The projection forms a partition between the two clamping points, so that the clamping points are separated from one another in the manner of a chamber. A chamber is understood to mean a partitioned area that does not have to be completely closed off. Starting from the DE 10 2015 105 757 A1 an improved chamber separation is carried out according to the invention. while at the DE 10 2015 105 757 A1 a chamber separation is produced by means of a partition wall of the contact part, ie material with good electrical conductivity, the chamber separation according to the invention takes place with the insulating material of the housing cover in cooperation with the insulating material housing.

A terminal point is understood to mean an area of electrical contact between a connection element, for example a busbar, and an electrical conductor. A conductor rail, also known as a current bar, is a largely rigid electrical conductor, for example a metal strip. An insulating housing is a housing made of an insulating, electrically non-conductive material, such as plastic.

The housing base body of the insulating housing is a carrier for components of the conductor connection terminal, for example for the busbar and other connection or contact elements. The housing body has a conductor insertion opening, which can also be designed as an elongate conductor entry channel, as a result of which the housing body provides a guide for inserted conductors. The conductor entry channel leads one or more electrical conductors to their respective terminal points at which the conductors can be clamped to the busbar. The basic body of the housing has a conductor connection space which adjoins the conductor entry opening. A conductor connection space is, for example, a cavity in which the terminal points are formed. For this purpose, a busbar and the stripped ends of inserted conductors that make electrical contact with the busbar are located in the conductor connection space. The housing body can more Have openings, for example, for actuating tools for actuating, for example opening a terminal point, or for test tools, for example to check the electrical potential present at a terminal point.

The housing cover forms a closure of the housing body. In principle, however, the insulating material housing can also have other components and can therefore be designed in several parts with more than two parts. The housing cover can preferably be releasably connected to the housing base body. In this way, even after the housing cover has been attached to the housing body, it is possible to check or maintain the conductor connection terminal located in the insulating housing. For example, plug-in, screw or snap-in connections can be considered as detachable connections.

A projection formed onto the housing cover is understood to mean a form of any shape protruding from the housing cover, which is suitable for forming a partition wall between two clamping points. The projection can be round, bar-like or L-shaped, for example. For example, in the case of an L-shape, the L-legs can be designed differently. For example, one leg can be round and rod-shaped and the other leg can be flat and, for example, approximately cuboid. The legs of such an L-shape can be made in one piece, but also in multiple pieces and made of different materials. When the housing cover is connected to the housing base body, the projection protrudes into the conductor connection space and forms a partition wall between two terminal points. The projection does not necessarily have to extend only in one direction or in one plane, but can run in different, in particular several, directions and angles. The projection can extend partially or entirely parallel to inserted conductors. The projection may extend partially or entirely across inserted conductors.

The indefinite term "a" is to be understood as such and not as a numeral and includes the literal sense of "at least one". Thus, the conductor terminal, for example, multiple conductor entry openings, multiple projections and have multiple partitions. The conductor connection terminal can also have more than two clamping points.

The projection of the conductor terminal can be made of an insulating material, ie not electrically conductive. The non-electrically conductive separation of the terminal points enables a defined current transfer exclusively at the terminal points.

The projection can be formed in one piece with the housing cover. A one-piece design of the projection with the housing cover simplifies the production of the housing cover, which can be done, for example, using an injection molding process. If the projection is designed in one piece with the housing cover, no additional connecting means are required to connect the projection to the housing cover. In principle, however, it is also conceivable to connect a separately designed projection to the housing cover, for example by gluing. As a result, conductor connection terminals can also be retrofitted with a projection and thus retrofitted.

The conductor connection terminal can have a clamping spring to form clamping points in the conductor connection space. A clamping spring consists of a contact leg and a clamping leg. Together with the conductor rail, the clamping leg forms a clamping point in which an electrical conductor is clamped with spring force. A particularly reliable, proven and cost-effective formation of a clamping point is possible with a clamping spring. The clamping spring can be part of a contact element, which is designed, for example, as a sheet metal part with a clamping spring arranged on it or formed in one piece. An opening can be provided in the contact element, for example in the sheet metal part, for receiving or guiding an electrical conductor inserted into the conductor insertion opening. In principle, however, other means of forming a terminal point are also conceivable, for example screw connections, insulation displacement connections or the like.

The insulating housing can have a spring carrier as a support for one or more clamping springs. Here, the spring carrier carries or supports the entire clamping spring or individual legs, for example the clamping leg of the spring. The spring carrier can be provided as a separate insert that is inserted into the insulating housing and optionally fixed. It is preferred if the spring carrier is formed in one piece with the housing base body, as a result of which the manufacturing and assembly costs are significantly reduced. It is also conceivable that a part of the spring carrier, for example one half, is integrally formed on the housing base body and another part of the spring carrier, for example the other half, is integrally formed on the housing cover. This achieves increased rigidity of the spring support, so that improved support is made possible, since possible deformation or yielding of the spring support when a clamping leg of the clamping spring is deflected is minimized.

The conductor connection terminal can be designed as a double connection for two electrical conductors. The conductor connection terminal can have common or separate conductor entry openings for the two conductors. The two conductors can be provided for connection to a common electrical potential or to different electrical potentials. When connecting to different electrical potentials, a projection made of an insulating material molded onto the housing cover is particularly advantageous since it prevents current transfer between the conductors or between their terminal points. Double connections are preferred when space is limited. The dividing wall formed by the projection formed on the housing cover enables a particularly space-saving and space-optimized design of the double connection.

A common actuating device for at least two clamping points can be provided in the housing base body. This greatly simplifies handling when connecting electrical conductors. The actuating device can be, for example, an opening for an actuating tool or an actuating mechanism, for example a pusher. The actuating device is used to actuate a clamping point, for example to open or close the clamping point. When using a clamping spring to form the clamping point, the clamping spring can be shifted to open or close the clamping point. The Actuating device can be designed to interact with two clamping legs of the clamping spring arranged next to one another.

The projection can have an arcuate shoulder, which merges into a partition wall protruding from the shoulder towards the conductor connection space. A support or a guide for a clamping spring is additionally provided by the arcuate shoulder. One leg, in particular a clamping leg, of the clamping spring can rest on the arcuate shoulder and be laterally delimited and guided by the partition wall projecting perpendicularly from the shoulder. The dividing wall protruding from the shoulder can, in particular, protrude perpendicularly from the shoulder.

The arcuate shoulder can transition towards the housing cover into a wall protruding from the shoulder. In particular, the housing cover is not to be equated with the wall. Rather, a separate material tab is formed on the projection or adjoining the projection on the housing cover. The wall protruding from the shoulder can, in particular, protrude perpendicularly from the shoulder. Such a wall enables improved guidance of a clamping spring held by the arcuate shoulder. Such a wall can serve as a spacer between the clamping spring and the housing cover. Such a wall can also serve as an overload stop for a clamping spring that is deflected, for example, to open the clamping point.

The projection can have a connecting device for connecting the housing base body to the housing cover. The connecting device can be, for example, an opening for a screw. However, the connecting device is preferably a blind hole as an insertion opening that can interact with a pin on the housing base body, or a pin that can interact with a blind hole as an insertion opening on the housing base body. The connecting device can also be a latching device, for example a latching lug that can interact with a latching opening in the housing base body, or a latching opening that can interact with a latching lug formed on the housing base body. Through this a particularly simple attachment of the housing cover to the housing body is made possible.

In addition, the connecting device on the projection is offset further inwards compared to a connecting device on the housing edge of the insulating material housing. This enables the housing base body to be held better on the housing cover and protects the connection point from external influences, for example from dirt. At this position, the connection point does not interfere with the insertion of conductors into the conductor connection space.

The dividing wall formed by the projection can have a rounded and/or tapering edge in the direction of the conductor insertion opening. The curves of the partition are on the side of the partition facing the conductor insertion opening. Tapering is understood to mean a decreasing diameter of the partition wall in the direction of the conductor insertion opening, that is to say the partition wall becomes narrower in the direction of the conductor insertion opening. The guidance of inserted conductors is thus improved. The ends of the conductors are prevented from kinking or fanning out as a result of individual wires slipping off a sharp or wide edge of the partition. In this way, an electrical conductor that is inserted at an angle or at an angle is guided back in the direction of its terminal point.

At least in sections, the basic housing body can have a defined contour that deviates from a purely rectangular shape, and the housing cover can have a section with a negative contour to the contour. The contour and the negative form of the contour can be designed, for example, as an arc, zigzag or wavy contour. This simplifies the assembly of the housing cover on the housing base body, since the housing cover can only be fitted in a specific orientation. This ensures that the projection and the partition wall formed with it are automatically located in the intended position in the conductor connection space during assembly.

Alternatively or additionally, the housing body and the housing cover can have positioning elements to facilitate assembly. The positioning elements can be designed, for example, as elevations and depressions according to a positive locking pin-hole principle. They can also form a latching connection when they are plugged into one another, in that a slight undercut is provided for both positioning elements.

The housing cover forms a side wall of the insulating housing when the housing cover is placed on the housing body. When the housing body and housing cover are assembled, the housing cover forms a lateral closure of the conductor connection space. A lateral termination or a side wall is understood to mean an area of the insulating material housing which runs essentially parallel to the conductor insertion direction. In principle, all four side walls of the insulating material housing running parallel to the conductor insertion direction can be considered for forming the projection. The assembly or connection direction of the housing cover with the housing body is transverse to the conductor insertion direction. The housing cover can be a substantially flat part of the insulating housing, in which the projection represents the only significant elevation from the plane of the housing cover. By molding the projection onto a housing cover designed as a side wall, the projection can have a comparatively small extent in order to achieve the desired position in the conductor connection space between two terminal points.

The Figures 1 to 7 show a conductor terminal 1 according to the invention or individual components of the conductor terminal 1. This has an insulating material housing with a housing base body 4a and a lateral housing cover 4b. The housing base body 4a has two conductor insertion openings 9, into which two conductors 2 are inserted and which each form a clamping point 6 with a busbar 3 and a clamping spring 10 in a conductor connection space 5. As a result, an electrical contact between the conductors 2, the spring clamps 10 and the busbar 3 is made. The conductor entry openings 9 are designed as elongated conductor entry channels. As in figure 1 As can be seen, the conductors are not straight but inserted into the conductor insertion openings 9 at different angles. This is intended to illustrate the fact that in practice, conductors, particularly in the case of conductor entry openings, which are required for conductors with different diameters are not always inserted straight and parallel to the side walls of the conductor entry openings. In order to prevent a conductor 2 from accidentally reaching the terminal point 6 of another conductor 2, a partition 8 is provided between the terminal points 6. The partition wall 8 is formed by a projection 7 formed onto the housing cover 4b. In the exemplary embodiment shown, the projection 7 has an L-shape when viewed from the side, with a round web which connects the flat, plate-shaped partition 8 of the projection 7 to the housing cover 4b. The partition wall 8 has a rounded edge 11 that tapers in the direction of the conductor insertion openings 9 in order to prevent conductors 2 from fanning out on the partition wall 8 . In this way, an electrical conductor 2 that is inserted at an angle is guided back in the direction of its terminal point 6 . In the projection 7 there is a connecting device, here in the form of a lower blind hole 16g, with which the housing cover 4b can be connected to the housing base 4a of the insulating material housing via a lower pin 16 arranged on the housing base 4a.

The figure 2 shows a housing body 4a of the conductor terminal 1. The housing body 4a has a total of four conductor entry openings 9, with two conductor entry openings 9 forming a common conductor entry opening 9 for two conductors 2 and are therefore not completely structurally separate from one another. The housing base body 4a shown is thus intended for a conductor connection terminal 1, which is designed as a multiple connection with two adjacent double connections for two conductors 2 each. The housing base body 4a has actuation openings 13 into which an in figure 7 Actuation element 20 shown can be inserted in order to open the terminal points 6. The terminal points 6 can, for example, by in figure 7 be formed clamping springs 10 shown and opened by moving the clamping springs 10, for example by means of a screwdriver. The housing body 4a has two in the figures 1 and 7 test openings 14 shown, via which the electrical potential at the terminal points 6 can be checked.

Inside the housing base body 4a there are two conductor connection spaces 5, one of which is shown in the perspective side view in FIG figure 2 can be seen. The conductor connection space 5 is a cavity in which the in figure 7 Busbar 3 shown, the clamping springs 10 and the conductor ends 2 are placed and form terminal points 6. To hold and guide the clamping springs 10, the housing body 4a has a spring carrier 15. In the in the figures 2 , 4 , 5, and 6 shown embodiment, the spring support 15 is formed in two parts. A part 15' of the spring carrier 15 is formed in one piece with the housing base body 4a and the other part 15" of the spring carrier 15 is formed in one piece with the housing cover 4b, as a result of which the spring carrier 15 has overall improved basic rigidity. The projection 7 connects to the spring carrier part 15 "On or take the projection 7 and a housing wall of the housing cover 4b the spring carrier part 15" between them figure 3 shown example, however, no spring carrier part is formed, so that the spring carrier 15 corresponding thereto is completely contained in the housing base body 4a.

A lower pin 16 is formed on the spring carrier part 15` of the housing base body 4a and is intended to interact with the lower blind hole 16g in the projection 7 on the housing cover 4b in order to enable the housing cover 4b to be connected to the housing base body 4a. To improve the connection, a further upper blind hole 12 is made on the housing body 4a, which is connected to a further upper pin 12g (cf. 4 ) works together.

In the figure 4 it can be seen that the basic housing body 4a has an arcuate contour 17 in sections. For example, in figure 4 recognizable that the housing cover 4b has a negative contour 18 of the arcuate contour 17 of the housing body 4a. When the housing cover 4b is placed on the housing base body 4a, the contour 17 and the negative contour 18 have the effect that the housing cover 4a can only be installed in such an orientation of the two housing parts relative to one another that the negative contour 18 comes into contact with the contour 17 . This effect is additionally by means of two in the Figures 5 and 6 shown positioning elements X and X 'supported, which also form a positive fit by plugging into each other, which allows a correct orientation of the housing parts. This simplifies assembly and at the same time ensures that the projection 7 and the partition wall 8 formed by it are guided to the correct position in the conductor connection space 5 .

In figure 2 it can be seen that a mounted on the housing base body 4a and, for example, in figure 3 shown housing cover 4b forms a side wall of the insulating housing. By molding the projection 7 onto a housing cover 4b designed as a side wall, the projection 7 can have a comparatively small extent in order to reach the desired position in the conductor connection space 5 between two clamping points 6 .

The figure 3 shows the housing cover 4b of the insulating material housing 4 of the conductor terminal 1. A projection 7 is formed on the largely flat housing cover 4b, which protrusion 7 forms a partition wall 8 for two in figure 1 shown terminal points 6 forms. In figure 3 it can be seen that the dividing wall 8 becomes narrower in one direction and thus tapers, as a result of which a conductor 2 touching the dividing wall 8 is prevented from fanning out. The projection 7 is formed as an arcuate shoulder and serves as a support for a clamping leg of the spring clamp 10. On the side of the projection 7 facing the housing cover 4b, a wall 19 is formed adjoining it. A spring clip 10 resting on the projection 7 is thus securely delimited laterally by the partition 8 and the wall 19, as a result of which improved guidance of the spring clip 10 is achieved. The housing cover 4b has an arcuate negative contour 18 in relation to the arcuate contour 17 of the housing body 4a. When the housing cover 4b is placed on the housing base body 4a, the contour 17 and the negative contour 18 have the effect that the housing cover 4a can only be installed in such an orientation of the two housing parts relative to one another that the negative contour 18 comes into contact with the contour 17 . This simplifies assembly and at the same time ensures that the projection 7 and the partition wall 8 formed by it are guided to the correct position in the conductor connection space 5 .

When placed on the housing base body 4a, the housing cover 4b forms a side wall of the insulating housing. The housing cover 4b thus delimits the conductor connection space 5 laterally and closes it off. The side wall is a wall of the insulating material housing that runs essentially parallel to the conductor insertion direction. In principle, all four side walls of the insulating material housing running parallel to the conductor insertion direction can be considered for forming the projection 7 .

figure 6 shows the housing base body 4a of the conductor connection terminal 1 with an inserted busbar 3 and a spring clamp 10. The spring clamp 10 is designed as a double spring with a common contact leg and two clamping legs 22 and can form a clamping point 6 with two inserted conductors via each clamping leg 22. The partition wall 8 of the housing cover 4b is positioned in the slot between the two clamping legs 22 when the housing cover 4b is put on.

figure 7 shows the conductor terminal 1 in a transparent sectional view. Two conductors 2 are inserted into the conductor insertion openings 9 . The ends of the conductors 2 protrude into the conductor connection space 5 and form a clamping point 6 with a spring clamp 10 designed as a double spring. This creates an electrical contact between the conductors 2, the spring clamps 10 and the busbar 3 . A part of the clamping spring 10 rests on the spring carrier 15 . The clamping spring 10 can be displaced counter to its direction of spring force in order to open the clamping point 6 . For this purpose, an actuating element 20 can be inserted into the actuating opening 13 and the spring clamp 10 can be displaced in the direction of the spring carrier 15 .

The conductor terminal 1 has a two-piece insulating housing with a housing body 4a and a housing cover 4b. The housing cover 4b is hidden in this side view in order to enable a view of the inside of the conductor terminal 1. However, the connecting means is in the form of upper blind hole 12 with upper pin 12g and lower blind hole 16g with lower Pins 16 are shown as parts of the housing body 4a and the housing cover 4b, as well as the partition wall 8 formed by the projection 7 of the housing cover 4b. When the housing cover 4b is in place on the housing body 4a, the partition wall 8 is positioned in the conductor connection space 5 in such a way that it lies between the terminal points 6 and prevents the inserted conductors 2 from being guided past their respective intended terminal points 6 in the conductor connection space 5.
