Description

The invention relates to a connecting device according to the preamble of claim 1 and a method according to the preamble of claim 12.

Electrical devices, such as machines and devices, are grounded for protection. For this purpose, electrically conductive components of the devices to be secured, in particular housing components, are connected to an earth line. The earth line is connected to an operational earthing of the supply voltage network. End users can also use the facilities together or separately via protective earth e.g. be earthed in the ground.

To ground the electrical devices together, a grounded earth conductor is connected to all devices. A continuous earth conductor is used for this.

Connection devices for such earth conductors are from the WO 2016/023908 known.

In the 7a to 7c and 8a to 8c are connection devices 1 shown according to the prior art. These have one or more terminal connections 3rd on. Continuous conductors to be connected can be connected to these 2nd be connected. The respective connection device 1 also has a connector body 4th made of a conductive material. This is attached to a mounting base, especially on a mounting rail 5 made of metal. For mounting one or more of the connection bodies 4th points the mounting rail 5 one or more through bores, as a rule predrilled in a grid, for example 16 (please refer 7c ) on.

The respective through hole 16 in the mounting rail 5 is assembled by a screw 15 penetrated into a corresponding threaded hole 17th of the connector body 4th is screwed in. The disadvantage is that the screw 15 exactly through the pre-drilled through opening 16 into the threaded hole 17th must be introduced. This requires a very precise alignment of the connector body 4th , which complicates the assembly.

• Schritt 10: Kabel innerhalb von ggf. vorhandenen Kabelkanälen müssen von der Bohrstelle beseitigt werden, um die Kabel nicht zu beschädigen und die Personensicherheit zu gewährleisten.
• Schritt 20: Es ist jeweils eine Durchgangsbohrung zur Befestigung der Potentialausgleichsklemme zu markieren und zu körnen.
• Schritt 30: Es ist ein Vorbohren mit einem kleineren Bohrerdurchmesser und ein anschließendes Aufbohren auf einen Nenndurchmesser durchzuführen. Anschließend muss die Bohrung entgratet werden, um scharfe Kanten zu verhindern.
• Schritt 40: Entstandene Metallspäne müssen entfernt werden. Andernfalls kann es zu einer Beschädigung der Leiterisolierung der im Kabelkanal verlegten Leiter kommen.
• Schritt 50: Die Potentialausgleichsklemme muss mit einer Gewindeausprägung genau über dem Bohrloch platziert werden.
• Schritt 60: Die Potentialausgleichsklemme kann nun mit einer Schraube an der Unterlage - in der Regel ein Kabelkanal - befestigt werden.
• Schritt 70: Nachdem die Potentialausgleichsklemme befestigt ist, kann der Leiter in die Klemmstelle eingeführt werden und mithilfe des Gewindestiftes fixiert werden.

Overall, according to the prior art, the flowchart of FIG 6 for the assembly of equipotential bonding terminals with steps 10th , 20th , 30th , 40 , 50 , 60 and 70 :

• step 10th : Cables within any existing cable ducts must be removed by the drilling site in order not to damage the cables and to ensure personal safety.
• step 20th : A through hole for attaching the equipotential bonding terminal must be marked and punched.
• step 30th : Pre-drill with a smaller drill diameter and then drill to a nominal diameter. The hole must then be deburred to prevent sharp edges.
• step 40 : Metal swarf must be removed. Otherwise the conductor insulation of the conductors laid in the cable duct may be damaged.
• step 50 : The equipotential bonding clamp must be placed with a thread type exactly above the drill hole.
• step 60 : The equipotential bonding terminal can now be attached to the base with a screw - usually a cable duct.
• step 70 : After the equipotential bonding clamp is attached, the conductor can be inserted into the clamping point and fixed using the grub screw.

The connection device according to the technical teaching of WO 2016/023908 has otherwise proven itself very well in practice, but an even simpler assembly of the connection body of the connection device on a mounting base is desirable. It is the object of the invention to create a connection device which is easier to mount in this sense.

The object is achieved with a connection device according to claim 1 and by the method of claim 12. Advantageous embodiments are specified in the subclaims.

According to claim 1, a connection device for connecting an electrical device to at least one continuous electrical conductor, in particular an earth conductor, is created, with a connection body made of an electrically (well) conductive metal (such as copper or aluminum), the at least one terminal connection for connecting the at least has a continuous electrical conductor, the connecting device having at least one or more magnets with which the connecting device can be fastened on a mounting base, so that an electrically conductive connection between the connecting body made of electrically conductive metal and the mounting base, in particular the mounting rail, made of electrically conductive Metal is present.

If at least one magnet is described below, the solution can also be used correspondingly for a plurality of magnets.

In this way, the connection device can be fastened virtually at any point on the mounting base correspondingly made of ferromagnetic material. In this way, the connection is made easier since the connection device for fastening can no longer be positioned so precisely that a screw hits the exact location of a through hole.

The invention is particularly suitable for a connection device in which the terminal connection has a clamping means which conductively connects the electrical conductor to the connecting body in a contact position either directly or via a holding means. This is because both the connection of the at least one conductor to the connecting device and the mounting of the connecting device on the mounting base are advantageously simple.

It can advantageously be provided that the at least one magnet is a permanent magnet. The assembly base then preferably consists entirely or in sections of a ferromagnetic material or metal.

It can be advantageously and simply provided that the at least one magnet is inserted into an opening of the connection body. This is because the magnet can be easily accommodated and also attached to the connector body.

It can further preferably be provided that the at least one magnet is set back into the opening of the connection body in such a way that it does not touch the mounting base in the assembled state. This is how direct conductive contact between the connection body and the metal mounting base can be ensured in a particularly simple manner.

The invention also provides a connection device according to one of the claims relating thereto with a mounting base, the mounting base being designed as a mounting rail which consists entirely or in sections of a ferromagnetic material. It can further be provided that the mounting base and the connector body each have one or more corresponding positive locking means such as corresponding steps in order to further optimize the seat of the connector device on the mounting rail in one direction in any case. These positive locking means can be designed and / or act in various ways. It is conceivable that one or more of the form-fitting means are designed to secure against translational displacement. However, it is also conceivable that one or more of the form-fitting means are designed to ensure that the connecting device is prevented from rotating on the mounting rail.

This can be achieved, for example, by providing at least two dowel pins on the side of the connection device facing the mounting rail, which press into the mounting device when the connection device is placed on it. The form-locking means can also be designed in another way, e.g. as a locking hook or the like

The 1a to 1d each show a first embodiment of a connection device 1 .

The connection device 1 can be used to connect at least one continuous electrical conductor 2nd and / or also for the electrically conductive connection of two or more continuous electrical conductors 2nd be trained. For this purpose, it has one, two or more terminal connections 3rd on that in a connector body 4th are formed from an electrically highly conductive metal. The terminal connections 3rd can be constructed the same as shown or in different ways. The connection device 1 can be formed point-symmetrical to an axis of symmetry. This is advantageous but not mandatory.

The connector body 4th can be for a continuous conductor to be connected 2nd at least one indentation each 11 have, which are in an extension direction of the electrical conductor 2nd extends and the connector body 4th can prevail in this direction. The respective indentation 11 is designed to be open at the side in such a way that the respective continuous conductor radially into the indentation 11 is insertable.

In the connection device shown 1 is for every electrical conductor 2nd (please refer 1d ), or for each terminal connection 3rd one movable holding device each 31 intended. With the connection device 1 act the holding means 31 each directly with the same terminal connection 3rd assigned clamping means 32 together.

It can advantageously be provided that the respective connection device 1 for pivoting the holding means 31 of the terminal connection 3rd has a rotary shaft (not shown here). The holding device 31 is rotatably arranged on the rotary shaft, while the free ends of the rotary shaft are rotatable in the connector body 4th are stored. The holding device 31 is in a slot 18th housed the perpendicular to the indentation 11 is provided and this crosses.

To the indentation 11 in the connector body 4th to be closed, the holding means 31 and the rotating shaft rotated together around an axis that is parallel to the conductor 2nd lies until one leg of the preferably multi-leg, self-angled holding means 31 into the respective indentation 11 of the connector body 4th intervenes. The holding device 31 is from an open position in which the electrical conductor 2nd into the respective indentation 11 can be inserted, moved into a closed position.

The holding device 31 holds the electrical conductor 2nd thus in a radial direction around the direction of extension in the indentation 11 . The holding device 31 is rotatable here about the axis that extends in the direction of extension of the conductor 2nd extends and is reversibly rotatable in an opposite direction of rotation. The holding device 31 can also be slidably provided (not shown).

The terminal connection 3rd each also has the clamping means already mentioned 32 on which on the holding means 31 acts and the holding means 31 and over this the electrical conductor 2nd in the closed position of the holding means 31 jammed. The clamping device 32 is preferably designed as a clamping screw. This is in a threaded hole in the connector body 4th screwed in. It can be rotated on a torque transmission contour using a tool. With its end, it acts on the holding means 31 and pivots this when screwing in. When unscrewing from the threaded hole of the connector body 4th becomes the holding means 31 however released in such a way that the connected conductor 2nd can be removed again. The rotary shaft can be designed as a clamping pin or clamping sleeve or in another way.

It is advantageous that the clamping means 32 not directly on the electrical conductor 2nd works. Rather, the electrical conductor 2nd between a connector body 4th and a first leg of the holding means 31 jammed. This is the terminal connection 3rd this embodiment for electrical conductors 2nd different conductor cross-sections can be used.

Alternatively, it can also be provided that the free end of a clamping means 33 - In particular a clamping screw - directly on the outer circumference of the conductor 2nd acts and that the leader 2nd such in the indentation 11 is clamped (not shown here) or in a through hole 12th is clamped (see 2nd and 4a, b ). At this point, too, supplementary to the WO 2016/023908 referenced, which discloses further such embodiments.

The connector body 4th is preferably made of an electrically highly conductive material, such as copper or aluminum, so that it is the two conductors 2nd good electrical connection. He can also conduct himself with a mounting base, especially on a mounting rail 5 be connected from metal. He is on this mounting base, especially mounting rail 5 suitable to attach.

To the respective connection device 1 in or on a mounting rail 5 to position and fasten, the respective connection device 1 at least one magnet 6 , here four magnets 6 on that in here 1b and in 1c are clearly shown. The magnet or magnets is / are 6 advantageously designed as permanent magnets.

The magnet or magnets 6 are preferably each in a corresponding opening 7 in the respective connector body 4th used. The magnet or magnets 6 For this purpose, preferably have a cylindrical base body, so that the respective opening 7 can be produced simply and advantageously as a kind of cylindrical blind hole. The opening 7 but can also be designed continuously, for example in steps. Alternatively, the magnets 6 and / or the openings also have other basic geometries. For example, the magnets 6 be polygonal. The magnets 6 can in the hole 7 clamped and / or adhesive and / or attached in some other way.

Overall, there is an advantageously simple possibility for mounting the connection device 1 on a dedicated mounting rail 5 (see 3a to 3d ) because the connection device 1 through the magnets 6 at any point on the mounting rail 5 simply by placing it on the mounting base, especially the mounting rail 5 , can be fastened and also positioned if the assembly base consists entirely or in sections of ferromagnetic material.

It is advantageous that such a direct conductive connection between the underside of the connection device and the mounting base can be realized, which is not affected by the magnets. Rather, direct contact to an earth protection potential ( PE ) or for functional earthing ( FE ) getting produced. The current is transmitted directly via the contact surface between the connecting device and the mounting base, but the force is transmitted via spaced magnets.

The respective opening 7 points - see Fig. 1c - according to a preferred embodiment, a depth on the outer circumference T whose amount is slightly larger than the amount H of the respective magnet 6 so that an axial surface of each magnet 6 opposite the surface of the connector body 4th into the interior of the respective opening 7 is reset. The difference between the depth T and the height H should be as small as possible and in particular preferably less than 0.2 mm and a maximum of 0.5 mm. As a result, a good conductive connection between the connection body is made in a simple manner 4th and the mounting base, especially the mounting rail 5 , ensured.

The mounting rail 5 can be made of a ferromagnetic material, preferably of a ferritic steel or the like, or of another suitable magnetic material. Due to the opposite of the surface of the connector body 4th towards the inside of the opening spring back magnets 6 the connection between the connection device takes place 1 and the mounting rail 5 always between the electrically conductive connection body 4th and the mounting rail 5 .

In the embodiment of the connection device 1 after the 2a to 2d is one of the conductor connections as a terminal connection 3rd by type of 1 educated. The connection device 1 also has two additional terminal connections 3rd on, which are designed as screw connections, each with a clamping screw 33 directly clamping onto an outer diameter of a conductor 2nd acts on a respective through hole 17th of the connector body 2nd enforced.

To the respective connection device 1 in the mounting rail 5 to position and fasten, the respective connection device 1 again at least one, here two magnets 6 on ( 2 B and 2c ). These magnets too 6 are each in a designated opening 7 of the respective connector body 4th used, the depth on the outer circumference T whose amount is slightly larger than the amount H of the respective magnet 6 , so that the advantages described above result.

This in turn results in an advantageously simple possibility for mounting the connection device 1 in or on the intended mounting rail 5 .

Due to the opposite of the surface of the connector body 4th Magnets springing back in the direction of the opening interior 6 there is also again contact between the connection device 1 and the mounting rail 5 always through the electrically conductive connection body 4th and the mounting rail 5 .

The positioning and fastening function can be achieved by means of an additional positive locking device between the connection device 1 or the connector body 4th can be further optimized (see 4b and 4d ). The connector body can do this 4th a grading according to the type of a recess 13 have and the mounting rail 5 one geometrically with the recess 13 corresponding gradation 14 have with the mounting rail 5 can be formed in one piece and represents a kind of protection against displacement in at least one direction. These gradations optimize the fit of the connector body 4th in the manner of a locking device. They preferably secure against translational movement.

To 5 a) to i ) are one or more dowel pins on the connector body 34 , 35 intended. When the connection clamp is arranged on the mounting rail, they dig into the mounting rail, so that - for example by using several of the dowel pins 34 , 35 - A rotation lock against rotation of the mounting device on the mounting base or mounting rail is achieved in a simple manner. The spring pins can be in holes 36 of the connector body 4th be used and protrude slightly over the surface facing the mounting base. The dowel pins 34 , 35 can have a point for digging into the surface of the mounting base.

• Schritt 100: Kabel innerhalb der Kabelkanäle müssen - wenn überhaupt - nur geringfügig verschoben werden, weil nur ein minimaler Platzbedarf zur Montage notwendig ist.
• Schritt 200: die als Potentialausgleichsklemmen ausgestaltetem Anschlussklemmen werden zu dem metallischen Kabelkanal als Montagebasis geführt. Bei einem geringen Abstand wird die Potentialausgleichsklemme direkt durch die Magnetkraft an den Kabelkanal herangezogen und die Klemme ist montiert.
• Schritt 300: Nachdem die Potentialausgleichsklemme befestigt ist, kann der Leiter in die Klemmstelle eingeführt werden und mithilfe des Stiftes 34 auch einfach am Einbauort positionsfest arretiert werden.

Overall, the flowchart of FIG 9 for the installation of equipotential bonding terminals with magnets:

• step 100 : Cables within the cable ducts only have to be moved slightly, if at all, because only minimal space is required for installation.
• step 200 : The connection terminals designed as equipotential bonding terminals are led to the metallic cable duct as a mounting base. If there is a short distance, the equipotential bonding clamp is pulled directly to the cable duct by the magnetic force and the clamp is installed.
• step 300 : After the equipotential bonding clamp is attached, the conductor can be inserted into the clamping point and using the pin 34 can also be simply locked in place at the installation location.

It is particularly advantageous that, unlike according to the prior art, no machining of the mounting rail is necessary, the chips which have to be laboriously removed from the cable duct. It is also possible to install the new connection device while old cables are still in the cable duct. These would normally have to be removed for the drilling process.
