Description

The invention relates to a conductor connecting terminal for connecting electrical conductors to a busbar. The conductor connection terminal has an insulating housing with a basic housing body and a housing cover that can be connected to the basic housing body. The basic housing body has a conductor insertion opening, which opens into a conductor connection space in the basic housing body. 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 onto the conductor rail.

Such conductor 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 limb, which is a material tab bent out of the connecting spring element and forms a partition between the two clamping springs.

Based on this, it is an object of the present invention to provide an improved conductor terminal.

The object is achieved by the conductor terminal of the type mentioned in that a protrusion is formed on the housing cover, which protrudes into the conductor connection space when the housing cover is connected to the basic housing body and forms a partition between two clamping points.

This prevents in a particularly simple manner that inserted conductors are guided past the clamping point provided for them or come into contact with the clamping point of another conductor. A defined and reliable guidance of the conductors to be connected is ensured by the partition formed. The improved guidance is also ensured if conductors are inserted at larger angles and not parallel to the walls of conductor insertion openings. The manufacture and assembly of the conductor connection terminal is simplified by the projection, which forms the partition, on the housing cover and thus on the insulating material housing. Fewer manufacturing and assembly steps are necessary. Fewer parts to assemble are required than with conventional conductor connection terminals. The costs for production and assembly are significantly reduced. The conductor connection point does not require busbars or clamping springs that are specially shaped with partitions, but can be equipped with simple and therefore inexpensive busbars and clamping springs.

The projection forms a partition between the two clamping points, so that the clamping points are separated from one another like a chamber. A chamber is understood to be a partitioned area, which does not have to be completely closed. Starting from the DE 10 2015 105 757 A1 improved chamber separation is carried out according to the invention. While at the DE 10 2015 105 757 A1 If a chamber is separated by means of a partition of the contact part, that is to say an electrically highly conductive material, the chamber is separated according to the invention with the insulating material of the housing cover in cooperation with the insulating material housing.

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

The basic housing body of the insulating material housing is a carrier for components of the conductor connection terminal, for example for the busbar and further connection or contact elements. The basic housing body has a conductor insertion opening, which can also be designed as an elongated conductor insertion channel, as a result of which the basic housing body provides a guide for inserted conductors. The conductor entry channel leads one or more electrical conductors to their respective clamping points, at which the conductors can be clamped to the busbar. The basic housing body has a conductor connection space, which connects to the conductor insertion opening. A conductor connection space is, for example, a cavity in which the clamping points are formed. For this purpose, there is a conductor rail in the conductor connection space and the stripped ends of inserted conductors which make electrical contact with the conductor rail. The basic housing body can have further openings, for example for actuating tools for actuating, for example opening a clamping point, or for testing tools in order, for example, to test the electrical potential present at a clamping point.

The housing cover can form an end to the basic housing body. The insulating material housing can thus be made in two parts, consisting of the basic housing body and housing cover his. In principle, however, the insulating material housing can have further components and can therefore be constructed in several parts with more than two parts. The housing cover is preferably releasably connectable to the basic housing body. In this way, a check or maintenance of the conductor connection terminal located in the insulating material housing can be made possible even after the housing cover has been attached to the housing base body. Plug-in, screw-in or snap-in connections, for example, can be considered as detachable connections.

A projection formed on the housing cover is understood to mean a shape of any shape that projects from the housing cover and is suitable for forming a partition between two clamping points. The projection can, for example, be round, web-like or L-shaped. For example, in the case of an L-shape, the L-legs can have different designs. 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 several parts and also made of different materials. When the housing cover is connected to the basic housing body, the projection protrudes into the conductor connection space and forms a partition between two clamping points. The projection does not necessarily have to extend in one direction or in one plane, but can have a course in different, in particular several directions and angles. The protrusion can extend partially or entirely parallel to inserted conductors. The protrusion can extend partially or entirely across the inserted conductors.

The indefinite term "a" is to be understood as such and not as a numerical word and includes the sense of the word "at least one". The conductor connecting terminal can thus also have, for example, a plurality of conductor insertion openings, a plurality of projections and a plurality of partition walls. The conductor connection terminal can also have more than two terminal points.

The projection of the conductor connection terminal can be made of an insulating material, that is to say it cannot be electrically conductive. The non-electrically conductive separation of the terminal points enables a defined current transfer only 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, with an injection molding process. In the case of a one-piece design of the projection with the housing cover, no additional connecting means for connecting the projection to the housing cover are required. In principle, however, it is also conceivable to connect a separately designed projection to the housing cover, for example by gluing. In this way, conductor connection terminals can also be retrofitted with a protrusion 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 busbar, the clamping leg forms a clamping point in which an electrical conductor is clamped with spring force. With a clamping spring, a particularly reliable, proven and inexpensive formation of a clamping point is possible. 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 thereon or formed in one piece. A breakthrough 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 clamping point are also conceivable, for example screw connections, insulation displacement connections or the like.

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

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 insertion 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 a current transfer between the conductors or between their terminal points. Double connections are preferred when space is limited. The partition 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 basic housing body. This considerably 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 serves to actuate a clamping point, for example opening or closing the clamping point. When using a clamping spring to form the clamping point, the clamping spring can be moved to open or close the clamping point. The actuating device can be designed to cooperate with two clamping legs of the clamping spring arranged next to one another.

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

The arcuate heel can merge towards the housing cover in a wall protruding from the heel. In particular, the housing cover is not to be equated with the wall. Rather, a separate material flap is integrally formed on the projection or subsequently on the projection on the housing cover. The wall protruding from the heel can in particular protrude vertically from the heel. 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 deflected, for example, to open the clamping point.

The projection can have a connecting device for connecting the basic housing body to the housing cover. The connecting device can be an opening for a screw, for example. However, the connecting device is preferably a blind hole as a plug-in opening which can cooperate with a pin on the basic housing body, or a pin which can interact with a blind hole as a plug-in opening on the basic housing body. The connecting device can also be a latching device, for example a latching lug that can interact with a latching opening in the basic housing body, or a latching opening that can interact with a latching lug formed on the housing basic body. This enables a particularly simple fastening of the housing cover to the basic housing body.

In addition, the connecting device on the projection is offset further inward compared to a connecting device on the housing edge of the insulating material housing. This enables an improved hold of the basic housing body on the housing cover and protects the connection point from external influences, for example from dirt. The connection point does not interfere with the insertion of conductors into the conductor connection space at this position.

The partition formed by the projection can have a rounded and / or tapered 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. A taper is understood to mean a decreasing diameter of the partition wall in the direction of the conductor insertion opening, that is to say that the partition wall becomes narrower in the direction of the conductor insertion opening. The leadership of introduced conductors is thus improved. It prevents the wire ends from kinking or fanning out by sliding individual wires off a sharp or wide edge of the partition. Thus, an electrical conductor, which is inserted at an angle or at an angle, is again directed towards its clamping point.

The basic body of the housing can have, at least in sections, a defined contour that deviates from a pure rectangular shape, and the housing cover can have a section with a negative contour to the contour. The contour and the negative shape of the contour can for example be designed as an arc, zigzag or wave contour. This simplifies the assembly of the housing cover on the housing base body, since the housing cover can only be put on in a certain orientation. This ensures that the protrusion and the partition wall formed with it automatically attach to the they are in the intended position in the conductor connection compartment.

As an alternative or in addition, the housing base body and the housing cover can have positioning elements to facilitate assembly. The positioning elements can be designed, for example, as an elevation and depression according to a pin-hole principle that forms a positive fit. Likewise, they can form a latching connection in an inserted state by providing a slight undercut of both positioning elements.

The housing cover can form a side wall of the insulating material housing when the housing cover is placed on the basic housing body. When the basic housing body and the housing cover are assembled, the housing cover forms a lateral termination of the conductor connection space. A lateral termination or a side wall is understood to mean an area of the insulating material housing that runs essentially parallel to the direction of insertion of the conductor. Basically, all four side walls of the insulating material housing running parallel to the direction of insertion of the conductor can be considered for the molding of the projection. The assembly or connection direction of the housing cover with the housing base body is transverse to the direction of insertion of the conductor. The housing cover can be an essentially flat component of the insulating material housing, in which the projection represents the only essential elevation from the plane of the housing cover. As a result of the projection being molded onto a housing cover designed as a side wall, the projection can have a comparatively small extension in order to achieve the desired position in the conductor connection space between two clamping points.

The 1 to 7 show a conductor terminal according to the invention 1 or individual components of the conductor connection terminal 1 . This has an insulating housing with a basic body 4a and a side cover 4b . The main body of the housing 4a has two conductor entry openings 9 , in the two conductors 2nd are introduced and that in a conductor connection compartment 5 one clamping point each 6 with a track 3rd and one clamp spring each 10th form. This creates an electrical contact between the conductors 2nd , the spring clips 10th and the track 3rd manufactured. The conductor entry openings 9 are designed as elongated conductor entry channels. As in 1 you can see the conductors are not straight, but at different angles into the conductor insertion openings 9 introduced. This is intended to clarify the fact in practice that conductors, in particular in the case of conductor insertion openings which are suitable for conductors with different diameters, are not always inserted straight and parallel to the side walls of the conductor insertion openings. To prevent a ladder 2nd accidentally to the terminal point 6 another leader 2nd arrives, is a partition 8th between the terminal points 6 intended. The partition 8th is through a to the housing cover 4b molded projection 7 educated. The lead 7 seen in the embodiment shown, has an L-shape with a round web, which the flat, plate-shaped partition 8th of the lead 7 with the housing cover 4b connects. The partition 8th has one towards the conductor insertion openings 9 tapered, rounded edge 11 to unravel conductors 2nd on the partition 8th to prevent. This becomes an electrical conductor 2nd , which is inserted at an angle, back towards its clamping point 6 directed. In the lead 7 a connecting device, here in the form of a lower blind hole 16g provided with which the housing cover 4b via one on the housing base 4a arranged lower pin 16 with the main body of the housing 4a of the insulating housing can be connected.

The 2nd shows a housing body 4a the conductor terminal 1 . The main body of the housing 4a has a total of four conductor entry openings 9 , each with two conductor insertion openings 9 a common conductor entry opening 9 for two conductors 2nd form and are therefore not structurally completely separated from each other. The basic body shown 4a is therefore for one Conductor terminal 1 thought of as a multiple connection with two adjacent double connections for two conductors each 2nd is trained. The main body of the housing 4a has actuation openings 13 in which an in 7 Actuator shown 20th can be introduced to the terminal points 6 to open. The terminal points 6 can for example by in 7 shown clamping springs 10th be formed and by displacement of the clamping springs 10th , for example by means of a screwdriver. The main body of the housing 4a has two in the 1 and 7 shown test openings 14 , via which the electrical potential at the terminal points 6 can be checked.

Inside the main body of the housing 4a there are two conductor connection rooms 5 , one of which is shown in perspective side view in 2nd can be seen. The conductor connection compartment 5 is a cavity in which the in 7 shown busbar 3rd who have favourited Clamping Springs 10th and the leader ends 2nd be placed and nips 6 form. For holding and guiding the clamping springs 10th has the main body of the housing 4a a spring support 15 . In the in the 2nd , 4th , 5 , and 6 The embodiment shown is the spring support 15 molded in two parts. A part 15 ' of the spring support 15 is in one piece with the basic body of the housing 4a trained and the other part 15 " of the spring support 15 is in one piece with the housing cover 4b trained, whereby the spring support 15 overall improved basic rigidity. The lead 7 connects to the spring support part 15 " to take the lead 7 and a housing wall of the housing cover 4b the spring support part 15 " between themselves. In the in 3rd shown example, however, no spring support part is molded, so that the corresponding spring support 15 completely in the main body 4a is included.

On the spring support part 15 ' of the main body of the housing 4a is a lower spigot 16 integrally molded to cooperate with that on the housing cover 4b in the lead 7 located lower blind hole 16g is provided to connect the housing cover 4b with the main body of the housing 4a to enable. To improve the connection is on the housing base 4a another top blind hole 12th introduced that with another, on the housing cover 4b molded top pin 12g (see. 4th ) interacts.

In the 4th it can be seen that the main body of the housing 4a sections of an arcuate contour 17th Has. For example, in 4th recognizable that the housing cover 4b a negative contour 18th the arcuate contour 17th of the main body of the housing 4a Has. When putting on the housing cover 4b on the main body of the housing 4a is through the contour 17th and the negative contour 18th causes the assembly of the housing cover 4a can only take place in such an orientation of the two housing parts to one another in which the negative contour 18th for contact with the contour 17th is coming. This effect is further enhanced by two in the 5 and 6 Positioning elements X and X` shown, which also form a positive fit by plugging into each other, which enables correct orientation of the housing parts. This simplifies assembly and at the same time ensures that the projection 7 and the partition formed by it 8th to the correct position in the conductor connection compartment 5 be performed.

In 2nd can be seen that a on the main body 4a put on and for example in 3rd shown housing cover 4b forms a side wall of the insulating material housing. By shaping the projection 7 to a housing cover designed as a side wall 4b can the lead 7 have a comparatively small expansion to the desired position in the conductor connection space 5 between two clamping points 6 to reach.

The 3rd shows the housing cover 4b of the insulating housing 4th the conductor terminal 1 . On the largely flat housing cover 4b is a head start 7 molded onto the partition 8th for two in 1 shown clamping points 6 forms. In 3rd can be seen that the partition 8th becomes narrower in one direction and thus tapers, causing the partition to be fanned out 8th touching conductor 2nd is prevented. The lead 7 is designed as an arcuate shoulder and serves as a support for a clamping leg of the spring clip 10th . On the case cover 4b facing side of the projection 7 is a wall adjacent to them 19th educated. One on the ledge 7 overlying spring clip 10th is thus safe from the partition 8th and the wall 19th laterally limited, which improves the guidance of the spring clip 10th is achieved. The housing cover 4b has an arcuate negative contour 18th in relation to the arcuate contour 17th of the main body of the housing 4a . When putting on the housing cover 4b on the main body of the housing 4a is through the contour 17th and the negative contour 18th causes the assembly of the housing cover 4a can only take place in such an orientation of the two housing parts to one another in which the negative contour 18th for contact with the contour 17th is coming. This simplifies assembly and at the same time ensures that the projection 7 and the partition formed by it 8th to the correct position in the conductor connection compartment 5 be performed.

The housing cover 4b forms in one on the main body of the housing 4a attached state a side wall of the insulating housing. Consequently limits the housing cover 4b the conductor connection compartment 5 sideways and closes it off. The side wall is a wall of the insulating material housing which runs essentially parallel to the direction of insertion of the conductor. Basically, all four side walls of the insulating housing that run parallel to the direction of insertion of the conductor come for the molding of the projection 7 into consideration.

6 shows the main body of the housing 4a the conductor terminal 1 with an inserted track 3rd and a spring clip 10th . The spring clip 10th is a double spring with a common contact leg and two clamping legs 22 executed and can with two inserted conductors over each clamping leg 22 a nip 6 form. The partition 8th of the housing cover 4b is when the housing cover is put on 4b in the slot between the two clamping legs 22 positioned.

7 shows the conductor terminal 1 in a transparent sectional view. There are two leaders 2nd into the conductor entry openings 9 introduced. The ends of the ladder 2nd protrude into the conductor connection compartment 5 and form with a spring clip designed as a double spring 10th a nip 6 . This creates an electrical contact between the conductors 2nd , the spring clips 10th and the track 3rd manufactured. Part of the clamp spring 10th lies on the spring support 15 on. The clamp spring 10th can be moved against the direction of the spring force around the clamping point 6 to open. For this purpose, an actuating element 20th into the actuation opening 13 be introduced and the spring clip 10th towards the spring support 15 relocate.

The conductor terminal 1 has a two-part insulating housing with a basic body 4a and a housing cover 4b . The housing cover 4b is hidden in this side view to have a look inside the conductor terminal 1 to enable. However, the connector is in the form of an upper blind hole 12th with top pin 12g and bottom blind hole 16g with lower pin 16 as parts of the main body of the housing 4a and the housing cover 4b as well as that of the lead 7 of the housing cover 4b formed partition 8th shown. The partition 8th is in the attached state of the housing cover 4b on the main body of the housing 4a such as in the conductor connection compartment 5 positioned that they are between the nips 6 lies and a passing the introduced ladder 2nd at their respective designated clamping points 6 in the conductor connection room 5 prevented.
