Description

The invention relates to a current-carrying profile connector with plug contacts and a Isolierstoffgehäuse, the receiving chambers for receiving a plug contact, conductor insertion openings on a first end side of the insulating material, which open into a respective receiving chamber, and insertion openings on a second end face of the insulating material, the first end face diametrically opposite and providing access to a respective receiving chamber has.

The invention further relates to a current-carrying arrangement with a plurality of current-carrying profiles, which have a carrier profile with a base surface, mutually parallel webs on the base surface and respectively by a pair of webs limited grooves and electrical conductors in such grooves, and with the above Stromführungsprofil- connectors.

For distribution of electrical energy in a building and for connecting lights at selectively selected positions busbar systems are known with current-carrying profiles, which have a comb-like cross-section with ridges and grooves formed therethrough and received in the grooves electrical conductors. In such current-carrying profiles, these electrical conductors are inserted in the grooves, e.g. received on the side walls of the webs and can be contacted by a tap connector with protruding into the grooves contacts electrically conductive. The current-carrying profiles usually have a carrier profile formed of plastic material, which is installed in a metal trough. They have a relatively large extension length. In the usual thermal stress, the electrical conductors formed of metal, the metal trough and the carrier profile formed of plastic expand differently. This can lead to significant changes in length or length shifts during operation. This is particularly relevant if several current-carrying profiles are arranged in alignment with one another in succession and the electrical conductors inserted therein are to be electrically connected to one another by plug-in contacts.

DE 10 2011 056 043 B4 discloses a busbar system having a current-carrying profile and a current tapping element which is placed on the current-carrying profile. An electrical connection of successively arranged current-carrying profiles can be realized by flying electrical conductors, which are clamped to such Stromabgriffelemente. The flexibility of the electrical conductors ensures the necessary length compensation for thermal expansion. However, such an arrangement is very expensive.

EP 1 284 033 B1 shows a current-carrying profile with a wire support member with grooves, in which electrical wires are accommodated. The wire support members have at their ends projections, which overlap with two merged wire support members overlapping. The projections thereby form a composite channel for the wire in the transition region of two wire-holding elements and allow, for example, temperature-dependent length compensation of the wire-holding elements to one another.

Based on this, it is an object of the present invention to provide an improved current-carrying profile connector and a current-carrying arrangement, which allows a reliable length compensation in the simplest possible and compact design.

The object is achieved with the current-carrying profile connector having the features of claim 1, by the current-carrying profile connector set according to claim 11 and by the current-carrying arrangement having the features of claim 12. Advantageous embodiments are described in the subclaims.

In a current-carrying profile connector of the type mentioned is proposed that the plug contacts are slidably received in a extending from the first end side to the second end face of the insulating plug-in direction in a respective receiving chamber. The plug contacts have on the side facing a conductor insertion opening a spring connection contact with a clamping spring for clamping an electrical conductor and on the side facing a plug opening formed from at least one pair of spring arm with two opposing spring arms fork contact or formed from a protruding in the insertion direction contact blade blade contact. The plug contacts have between the clamping spring of the spring connection contact and the fork or blade contact a stop for abutment of an electrical connector clamped to the spring connection contact, wherein the clamping spring is inclined towards the stop and in relation to the plugging direction.

The electrical connection of electrical conductors of fluently arranged in a row current management profiles is done with such current guide profile connectors. The electrical conductors of the current-carrying profiles can then each be inserted into a conductor insertion opening and clamped to the local spring connection contacts become. Two such current-carrying profile connectors can be plugged together at their plug-in openings, wherein a blade contact of a first current-carrying profile connector cooperates with a fork contact of a second current-carrying profile connector.

A current-carrying profile connector does not necessarily have to have the same type of plug contacts as either blade contacts or only fork contacts. In a current-carrying profile connector, also different types of plug-in contacts may be present in mixed form, such as e.g. Knife contacts and fork contacts.

Characterized in that the plug contacts are arranged displaceably on a respective receiving chamber of the insulating material, they can move in their insertion direction at a different longitudinal extent of the clamped electrical conductor and the carrier profile. Characterized in that two Stromführungsprofil connector are inserted into one another with their plug-in opening and there is provided a sliding knife-fork contact, such a movement of the blade contact can move relative to the fork contact without affecting the electrically conductive connection between the blade and fork contact becomes. The relative movement of a connector with a longitudinal extension of the clamped electrical conductor to the stationary insulating material while ensuring a stationary clamped electrical conductor spring clamp contact is achieved in that the electrical conductor abuts the stopper of the plug contact with its front side and fixed in position by the clamping spring on the Plug contact is clamped. This is achieved in that the clamping spring facing towards the stop and is inclined with respect to the plugging direction. Thus, the clamped to a plug-in electrical conductor of the current-carrying profile is prevented to one side by the stop and to the other side by the clamping spring to move relative to the plug contact. Nevertheless, a sliding movement remains possible by the pairing of a fork contact with a blade contact of the interlocking current-carrying profile connectors, in order to ensure the length compensation in this way.

For this purpose, the blade contact and / or the fork contact at least on the contact surfaces have a surface coating, which ensures an even better sliding movement with constant contact resistance. Such a surface coating may be provided by a noble metal overlay, such as e.g. be realized by gilding, by silver coating or the like.

The plug contacts may be integrally formed from a sheet metal part and have a bottom surface and from the opposite sides of the bottom surface projecting side walls. A conductor guide tunnel is provided by these side walls spaced apart and projecting in the same direction from the bottom surface. The plug contact has at least one clamping spring, which is each released from a side wall. For this purpose, the side wall in the region of the clamping spring can be cut free from the base plate or punched free and the side wall can be separated transversely to the plane of the bottom surface. Such integrally formed with the side wall and connected thereto clamping spring may then be bent out of the plane of the side wall in the direction of the opposite side wall. It is also conceivable that a separate clamping spring is connected to a side wall, for example by soldering, welding, caulking or other joining.

Such a plug contact is very simple, built by the projecting side walls stable and compact.

From the bottom plate, a material flap may protrude to form a stop. This material flap can be arranged in a space between the opposite side walls. Thus, the tunnel for insertion of an electrical conductor is bounded laterally by the two side walls, from below through the bottom plate and in the insertion direction by the material lables. An electrical conductor of the current-carrying profile introduced into the conductor guide tunnel between the side walls can then be led up to the material lug in order to lie there. In this case, the electrical conductor is clamped by the protruding from the side wall clamping spring on the plug contact and not only electrically contacted, but also fixed in position held on the plug contact.

The side walls may be oriented at an angle to each other at the transition to the fork or blade contact. In this way, the connector is further tapered in the insertion direction of the spring connection contact. This area formed by the mutually facing obliquely set side walls is preferably in the region in which the stopper is formed. Thus, the side walls at the transition from the spring connection contact to the fork or blade contact can be aligned at an angle to each other.

The obliquely aligned side wall portions may form the spring arms of a fork contact in a separate section from the bottom plate. This closes the Spring arms of the fork contact to the side walls of the plug contact and are kept stable by the one-piece connection. In addition, a sufficiently large current cross section is ensured in this way.

The pair of spring arms may then have a contact area at the spring arm ends remote from the spring connection contact, followed by insertion portions bent away from each other. Thus, an insertion funnel for inserting a blade contact is provided in the fork contact and realized at the oblique insertion sections subsequent contact area with low contact surface. Thus, the contact pressure of the fork contacts is concentrated on this contact area with a reduced area and in this way increases the surface pressure and reduces the contact resistance.

The obliquely aligned side wall portions may merge into adjacent contact lugs which extend parallel to each other and form a blade contact. This also achieves direct current transmission via the side wall sections into the blade contact with the greatest possible current cross section and stable construction. By the side by side extending contact lugs, which preferably abut each other, the risk of bending the blade contacts is reduced. The increased blade thickness is also advantageous in terms of achievable contact forces on the fork contacts, as they thus require no bias.

A ground contact can be slidably plugged into the plug contact and protrude from the plug contact.

This embodiment is in principle independent of the specific embodiment of current-carrying profile connectors.

The fact that a separate grounding contact is slidably and thus slidably plugged into a plug-in contact, the grounding contact fixed in position can remain connected to grounding potential, for example, the metal trough, even if the carrier profile or built-in electrical conductors move. Due to the displaceable plug contact of the earthing contact on a plug contact, which is used to connect two current-carrying profiles, a movement of the connector on the fixing of the ground contact does not affect, since they are slidably plugged together.

The ground contact may have a socket contact into which the contact tab of a connector described above is plugged. This contact lug of the connector can also be connected to a forked contact of a complementary connector to provide in this way a continuous wiring and at the same time a ground connection to protective earth (PE).

In a current-carrying arrangement of the type mentioned above, it is proposed that in each case a current-carrying profile connector is connected to the end face of two carrier profiles arranged one behind the other in alignment. The protruding from the front electrical conductor of the carrier profile are clamped to a respective spring terminal contact of a plug contact of the current-carrying profile connector. The electrical conductor abuts against the stop of the plug contact and is clamped with the clamping spring on the plug contact. The connected at the adjacent end faces of the two carrier profiles current guide profile connector interlock. A blade contact of a plug contact of a current guide profile connector is slidably contacted with a fork contact of a plug contact of the other current lead profile connector.

In this way, two carrier profiles arranged in alignment one behind the other are connected by a pair of complementary current-carrying profile connectors, which are respectively connected adjacent to each other on one end face of the two carrier profiles. The projecting from the carrier profiles electrical conductors are inserted into the conductor insertion openings of the current-carrying profile connector to be clamped with a spring connection contact. In the case of a longitudinal displacement, the plug contacts of the complementary current-carrying profile connectors can move relative to one another, whereby a sliding, linearly displaceable plug-in direction in the plug-in direction of the two complementary current-carrying profile connector and thus of the support profiles arranged in a row is ensured by the blade and fork contact arrangement ,

On a front side of a carrier rail, a first current-carrying profile connector can be plugged. This first current-carrying profile connector is then plugged together with a second complementary current-carrying profile connector in that they mesh in the region of their plug-in openings. A blade contact of a plug-in contact of one of these current-carrying profile connectors dips into a fork contact of a plug-in contact of the other current-carrying profile connector. In this way, a sliding, displaceable in the insertion direction contacting the two interconnected plug contacts is ensured.

With such a pair of complementary current-carrying profile connectors not only two carrier profiles arranged one behind the other can be electrically conductively connected to one another. An electrical tap or an electrical supply of energy or data can also take place on one end face. For this purpose, electrical connection lines can be inserted into conductor insertion openings of the second current-carrying profile connector and in each case clamped to a spring connection contact of a plug-in contact of the second current-carrying profile connector. The conductor insertion openings of the current-carrying profile connector can thus be used not only for clamping the electrical conductors of the carrier profiles. They are equally suitable for connecting independent electrical connection lines from the carrier profiles. These can be rigid or flexible, multi-wire electrical connection cables.

The insulating housing of the current-carrying profile connector can have an outer contour adapted to the end contour of the end faces of the carrier rail and can be inserted flush into the end-face contour. Thus, the current-carrying profile connector is fixed in position to the region of the end face of the carrier profile and prevents relative movement of the current-carrying profile connector relative to the carrier profile or at least severely limited.

The front side contour of the carrier profile and the outer contour of the current-carrying profile connector can have latching elements for locking the current-carrying profile connector to the carrier profile. In this way, it is still possible to lock the current-carrying profile connector after attaching to the front side of the carrier profile to the carrier profile and secure against pulling out. This locking can be so strong that the current-carrying profile connector fits snugly against the carrier profile and is held firmly by form-locking on the carrier profile.

1 shows a perspective view of two complementary current-carrying profile connectors 1a . 1b , each an insulating material 2a . 2 B to have.

At a first end 3 the insulating material housing 2a . 2 B are ladder entry openings 4 introduced, leading into receiving chambers for plug contacts. The insulating material housing 2a . 2 B have at a second end face 5 that the first front page 3 diametrically opposite, plug-in openings 6 which also provide access for a respective receiving chamber.

The insulating material housing 2a . 2 B are at their second front 5 and this second end face 5 surrounding plug-in area contoured so that the complementary current-carrying profile connector 1a . 1b can be plugged into each other.

2 shows a perspective partial sectional view of a current-carrying arrangement with a current-carrying profile 7 that made a carrier profile 8th and in the carrier profile built-in electrical conductors 9 is formed. The carrier profile 8th has a number of webs extending parallel to each other 10 , each one a groove 11 for receiving a respective electrical conductor 9 limit. It is clear that alternating grooves are provided with different depths, so that the electrical conductors 9 arranged on two levels. The electrical conductors 9 protrude at the end faces of the carrier profile 8th out of this to be contacted electrically conductive.

At the front side has the carrier profile 8th a platform 12 for mounting a current-carrying profile connector 1a . 1b ,

It becomes clear that the current-carrying profile connector 1a . 1b with his first front page 3 on the front side of the current-carrying profile 7 is plugged. The plug-in direction S is sketched with an arrow. The electrical conductors are diving 9 of the current-carrying profile 7 in each associated conductor insertion openings 4 of the current-carrying profile connector 1b in order to communicate in the interior with an invisible conductor connection contact.

3 shows the diametrically opposite end face of the carrier profile 7 out 2 , Even there protrude the electrical conductors 9 on two levels from the carrier profile 8th out. Also on this front page can be a power guide profile connector 1a with its the conductor entry openings 4 having front side 3 be plugged while doing so on the platform 12 rest.

It becomes clear that the contour of the current-carrying profile connector 1a . 1b in the area of conductor entry openings 4 or the first end face 3 so to the power supply profile 8th adapted is that the power guide profile connector 1a . 1b fitting on the platform 12 can be pushed with their side walls, in this way in the correct position to the electrical conductors 9 and the associated conductor insertion openings 4 to be positioned. The platform 12 has lateral, vertically projecting side walls, wherein the side walls in the attached state of the current-carrying profile connector 1a . 1b in recesses on the respective current-carrying profile connector 1a . 1b intervention.

It is still recognizable that the plug-in openings 6 on the second front side 5 the current-carrying profile connector 1a . 1b access to plug contacts 13 allow in the interior of the current-carrying profile connector 1a . 1b are recorded in respective recording chambers. This can be an electrically conductive contact between each pair of plug contacts 13 the first and second current-carrying profile connector 1a . 1b are made when they are nested.

4 shows a plan view of a section of a Stromführungsanordnung with the two nested Stromführungsprofil connectors 1a . 1b , It becomes clear that the current-carrying profile connector 1a . 1b a two-part insulating material housing 2a . 2 B each have a basic body 14 and a lid part 15 respectively. In the lid part 15 are the conductor entry openings 4 introduced, each to a receiving chamber 16 in the interior of the body 14 to lead. In these receiving chambers 16 is in each case a plug contact 17a . 17b introduced, which is longitudinally displaceable in the insertion direction S. This is one of the varying positions of the plug contacts 17a . 17b with respect to the adjacent lid part 15 clear. It can be seen that the distances between the cover part 15 which is a receiving chamber 16 limited, and arranged therein plug contact 17a . 17b can vary.

A first kind of plug contacts 17a each has a conductor connection contact 18 for clamping an electrical conductor 9 a current-carrying profile 7 and at the other end a knife contact 19 to form a plug contact terminal for the second plug contact 17b of the complementary current-carrying profile connector 1b ,

This second type of plug contacts 17b also have a conductor connection contact 18 for clamping the electrical conductor 9 a current-carrying profile 7 and at the other end a fork contact 20 , This is also formed by two obliquely placed spring arms, which is a knife contact 19 between them and clamp by spring force. It becomes clear that the knife contact 19 relative to the fork contact 20 in the insertion direction S is sliding, so that the insertion depth of the blade contact 19 in the fork contact 20 can vary.

It is clear that the plug contacts 17a . 17b each in the transition between the conductor connection contact 18 and the knife contact 19 or the fork contact 20 a stop 21 have, in the insertion direction in the flight of a conductor insertion opening 4 is arranged. When plugging in an electrical conductor 9 in a power guide profile connector 1a . 1b becomes the electrical conductor 9 so far in the conductor connection contact 18 of the respective connector 17a . 17b put that the front end of an electrical conductor 9 at the stop 21 abuts. This is the electrical conductor 9 but through the conductor connection contact 18 at the respective connector 17a . 17b fixed in position and can not retreat any more. With the help of the combination of the conductor connection contact 18 and the stop 21 becomes the electrical conductor 9 at a respective plug contact 17a . 17b fixed in position. For a linear expansion of the electrical conductor 9 shifts the attached plug contact 17a . 17b in the direction of insertion back and forth relative to the insulating material 2a . 2 B of the current-carrying profile connector. This is achieved by the fact that the plug contacts 17a . 17b slidable in a respective receiving chamber 16 are arranged and by the sliding contact between the blade contact 19 and the associated fork contact 20 a Relatiwerschiebung the two complementary mated together first and second connectors 17a . 17b is possible.

5 shows a sectional view of the current-carrying arrangement 4 in the second mating plane. Compared to the cut out 4 it becomes clear that the first connectors 17a or the second connector 17b are offset in height transversely to the insertion direction S, so that on a second insertion plane between two connectors 17a or. 17b one connector each 17a or. 17b a first mating plane is arranged.

From this sectional view it is also clear that the conductor connection contacts 18 the connector 17a . 17b by a respective spring terminal contact with two opposing clamping springs 22 are formed. These clamping springs 22 are each out of the plane of a sidewall 23 in the interior of the plug contact 17a . 17b exposed and point in the direction of the stop 21 , They are integral with the side walls 23 shaped and clawed in the clamped electrical conductor 9 so firm that this is not readily apparent from the attack 21 can be pulled away. The stop 21 thus limits the degree of freedom of movement of a clamped electrical conductor 9 in the plug-in direction S, while the conductor connection contact 18 with the two clamping springs 22 restricts the degree of freedom of movement in the opposite direction.

Again, by the different displacement positions of the first and second plug contacts 17a . 17b clear that these in nested condition by the blade and fork contacts 19 . 20 and the sliding contact caused thereby are relatively displaceable to each other. This allows different length expansions of the electrical conductors 9 relative to the carrier profiles 8th and the insulating housings 2a . 2 B the Stromführungsprofil connector can be compensated in a simple and reliable manner.

6 shows a perspective view of a first plug contact 17a with a knife contact 19 at one end. It becomes clear that the first plug contact 16a is integrally formed from a sheet metal part. He has a floor area 24 , from the opposite sides of the side walls 23 protrude. Visible is that on the opposite side walls 23 one clamping spring each 22 from a side wall 23 is released. For this purpose, the clamping spring 22 to the floor area 24 back and forth to the bottom surface 24 from the sheet material of the side wall 23 cut or punched free. The clamping springs 22 are off the plane of that sidewall 23 herausgebogen with which these are integrally connected. The two clamping springs 22 are diagonally in the interior of the respective plug contact 17a bent in and on the stop 21 aligned. Between the free ends of the clamping spring 22 and the attack 21 is a clamping distance available. The stop 21 is from the floor area 24 bent out so that the stop 21 in the same direction from the bottom surface 24 protrudes, like the side walls 23 and the clamping springs formed thereon 22 , With the help of the floor surface 24 and the side walls 23 For example, a conductor insertion tunnel is provided for an electrical conductor to be clamped, which is then connected to that through the clamping ends of the clamping springs 22 formed clamping point and guided with its front end to the stop 21 can trigger.

It is clear that the side walls 23 in the transition to the knife contact 19 are aligned obliquely to each other. These obliquely aligned side wall sections 25 go in each case parallel knife sections of the blade contact 29 together, the two-layer knife contact together 19 form.

The stop 21 is in the area between the obliquely aligned side wall portions 25 and the clamping end of the clamping springs 22 arranged.

It can be seen in the embodiment that on the side of the stop 21 that the clamping springs 22 (ie the spring tongues) diametrically opposite material tongues 36 from the sidewall sections 25 released and inside to stop 21 bent over. With these optional material tongues 36 becomes the stop 21 stabilized and the risk of kinking by a plugging in an electrical conductor 9 on the stop 21 reduced acting force.

The blade contact may optionally have a partial surface coating O in order to reduce sliding friction and thus improve the sliding properties. This surface coating may e.g. be realized by silvering or gilding of the contact area.

7 lets a perspective view of the second type of plug contacts 17b recognize. Also these plug contacts 17b are integrally formed from a sheet metal part and have a bottom surface 24 from the opposite sides of the floor surface 24 each side walls 23 protrude. The conductor connection contact 18 is like the first type of plug contacts 17a again by clamping springs 22 formed from the side walls 23 are exposed obliquely. Again, by the pair of spring clips 22 a funnel-shaped tapered conductor terminal connection is provided, in which the electrical conductor by the mutually resilient spring clips 22 is trapped. It becomes clear that the second type of plug contacts 17b which adhere to the clamping springs 22 subsequent, obliquely aligned side wall sections 25 the spring arms 26 a fork contact 20 form. These spring arms 26 have at their from the conductor connection contact 18 removed Federarmenden a contact area 27 , to the insertion bent away from each other 28 connect. These introductory sections 28 obliquely away from each other to an insertion funnel for inserting a blade contact 19 between the spring arms 26 the fork contact 20 provide.

Again, the optional material tongues 36 provided, consisting of the side wall sections 25 released and inside to stop 21 out of the plane of the respective side wall portion 25 are bent out.

8th shows a plan view of the current-carrying arrangement without the main body 14 of the insulating material housing 2a . 2 B , but with remaining lid part 15 , It becomes even clearer that the nested pairs of first and second plug contact 17a . 17b in the insertion direction S are relatively displaceable to each other, so that between the respective blade contact 19 and the associated, by the spring arms 26 formed fork contacts 20 a sliding contact is made.
