Definitions

  • the present invention relates to a clamp, in particular an installation clamp.
  • a clamp such as an installation clamp is used to electrically connect an electrical conductor.
  • An electrical conductor is electrically contacted via the terminal in order to electrically connect it via the terminal, for example, to another electrical conductor that is electrically contacted in the terminal and/or to an electrical device, in particular for its electrical supply.
  • the clamp simultaneously serves to mechanically hold and/or fix the electrical conductor.
  • the electrical conductor is electrically insulated by insulation or an insulating material
  • part of the insulating material has to be removed along a certain length so that electrical contact can be made with the electrical conductor. This step is called stripping.
  • the stripped part of the electrical conductor can then be electrically contacted with the terminal.
  • a disadvantage of stripping is the relatively complex removal of the insulating material. Above all, relatively large assembly forces are required to perform the stripping. As a result, it may be necessary to use an additional tool (e.g. a screwdriver) to apply the high forces required for stripping. Furthermore, the process of stripping is relatively time-consuming.
  • the invention is therefore based on the object of creating a clamp, in particular an installation clamp, which overcomes the disadvantages mentioned above.
  • a terminal should therefore be provided which can easily make electrical contact with an electrical conductor insulated with an insulating material.
  • a terminal according to the invention in particular an installation terminal, is provided for connecting an electrical conductor without stripping insulation.
  • the terminal has at least one conductor insertion area for inserting an electrical conductor insulated with an insulating material into the terminal in a conductor insertion direction.
  • the terminal has, for each conductor insertion region: an operating part which can be rotated about an axis of rotation; and a cutting contact with a cutting edge for cutting through the insulating material and making electrical contact with the electrical conductor, the cutting edge extending along an arc around the axis of rotation, and the cutting contact being connected to the actuating part in such a way that by rotating the actuating part about the axis of rotation the cutting contact is movable between a contacting position, in which the cutting edge crosses the conductor insertion area for electrical contacting with an inserted electrical conductor, and a release position, in which the cutting edge releases the conductor insertion area.
  • the clamp according to the invention has the advantage that the actuating forces for cutting through the insulating material are reduced.
  • the cutting edge meets the insulating material of the electrical conductor at a particularly advantageous angle (for example at an essentially right angle) due to its arcuate extension around the axis of rotation.
  • the cutting edge can displace the insulating material particularly well without high forces having to act on the cutting contact.
  • the electrical contacting of an electrical conductor with the terminal is therefore particularly simple. Due to the curved design of the cutting edge, this or a cutting opening formed at least partially by the cutting edge, for example in the form of a cutting slot, can advantageously be lengthened.
  • the cutting edge In the contacting position, the cutting edge can cross or pass through a conductor insertion plane that is parallel to the conductor insertion direction and to the axis of rotation.
  • the conductor insertion plane can be a (geometric) plane, for example a plane along which the conductor insertion area extends and/or a plane of symmetry of at least part of the conductor insertion area. This can be provided, for example, in the form of a conductor insertion channel.
  • the cutting edge In the release position, the cutting edge is preferably at a distance from the conductor insertion plane.
  • the axis of rotation is preferably provided in the conductor insertion area or in an extension thereof in the direction of conductor insertion. This results in a particularly compact terminal, which also enables simple electrical contacting of the conductor.
  • the axis of rotation is preferably transverse or perpendicular to the conductor insertion direction.
  • the cutting edge may at least partially define a cutting opening (or multiple cutting openings), wherein when the cutting contact electrically contacts the electrical conductor in the contacting position, the electrical conductor is at least partially provided in the cutting opening.
  • the cutting opening is preferably at least in part a cutting slot. The cutting opening brings about, in particular, a simple severing of the insulating material and simple electrical contacting and mechanical retention of the electrical conductor. In addition, the cutting contact is thus provided in a compact manner with respect to the electrical conductor.
  • the cutting opening can be formed by two cutting sections which are preferably formed integrally with one another; "Integral" means here particularly preferably that the cutting sections are formed together from a single cast, in one piece and/or in one piece, particularly preferably in one piece in the form of a one-piece stamped and bent part. This allows the cutting opening to be made easily.
  • the cutting sections of the cutting opening give an advantageous cutting effect, since the cutting sections can act on different sides and/or positions of the electrical conductor in order to cut through the insulating material. It is preferred if the electrical conductor is provided at least partially between the cutting sections in the contacting position.
  • the cutting sections are designed to be resilient transversely to the conductor insertion direction in order to electrically contact the electrical conductor in the cutting opening in a clamping manner. This results in a particularly reliable electrical contact between the cutting contact and the electrical conductor. Furthermore, an advantageous mechanical mounting of the electrical conductor can be provided by the clamping. In addition, electrical conductors with different cross sections and/or diameters can easily be electrically contacted due to the resilient design of the cutting sections.
  • the clamp preferably has an elastic element, for example a spring element, which is arranged in such a way that its restoring force presses the cutting edge against the electrical conductor, ie clamps it.
  • the elastic element is therefore preferably used to mechanically support the cutting contact.
  • the elastic element can be made of stainless steel and/or be provided in the form of a clasp.
  • the elastic element is provided, for example, in such a way that it encompasses the cutting contact and/or is provided in the manner of a sandwich with the cutting contact ("sandwich arrangement").
  • the cutting contact can have only one cutting opening or several cutting openings.
  • the multiple cutting openings can be arranged to contact different electrical conductors (in particular with different cross-sections and/or diameters), which are inserted into the terminal, for example, via different conductor insertion areas (preferably having two different insertion holes).
  • the cutting contact can have a cutting slot which is designed in multiple stages, for example in two stages, in order to form the plurality of cutting openings (e.g. first stage: first cutting opening; second stage: second cutting opening).
  • the arc can be an arc of a circle or an arc of an ellipse.
  • the cutting edge can have the same radial distance to the axis of rotation along the arc.
  • the cutting edge can be moved on a circular path with a defined radius with respect to the axis of rotation by rotating the actuating part. This results in a particularly compact terminal which can also make electrical contact with the electrical conductor with a reduced actuating force.
  • the cutting contact can be designed as an integral component, preferably as a stamped and bent part. This results in a particularly cost- and material-saving production of the cutting contact.
  • the terminal preferably has a contact part, the cutting contact having a contact section which is in electrical contact with the contact part only or at least in the contacting position.
  • this has the advantage that the cutting contact can simply be electrically connected to the contact part or electrically disconnected (released) from it via the actuating part. Above all, an electrical connection between the conductor and the contact part can thus be separated without the conductor having to be removed from the terminal.
  • a further advantage is that the optional electrical connection between the contact part and the contact section can be produced easily.
  • the cutting contact can be contacted, for example, with a further cutting contact or another electrical load via the contact part. For example, it can be provided that the contact section is separated and/or spaced apart from the contact part in the release position.
  • the contact section and the contact part can be designed to correspond in such a way that in the contacting position for electrical contacting they engage in one another like a comb and/or in a clamping manner. This results in a particularly advantageous electrical contact between the contact section and the contact part.
  • the clamping can also advantageously provide mechanical support for the cutting contact in the contacting position.
  • the contact part can be elongate and/or designed as a rail (busbar).
  • the contact part can be designed as a comb (as a so-called "connector comb” or "contact comb”).
  • the comb then preferably has one or more comb openings into which the one or more contact sections (if several cutting contacts are provided) can be pivoted.
  • the contact section is preferably designed as a contact fork.
  • the contact fork preferably has two projections (e.g. in the form of two tines) which can engage the comb. For example, a projection of a contact fork of a first cutting contact and a projection of a contact fork of a second cutting contact can engage in a common comb opening.
  • these can alternatively be connected to one another via one or more flexible electrical conductors, for example by these conductors being applied to the individual cutting contacts by material bonding (welding, soldering, etc.).
  • the contact section can protrude radially from the cutting contact with a contact area with respect to the axis of rotation.
  • the contact section can thus be provided in a particularly simple manner, for example by bending a section of the cutting contact.
  • the radially protruding contact area results in advantageous electrical contacting with the contact part, since the rotation of the cutting contact about the axis of rotation simply brings the contact area into electrical contact with the contact part.
  • the terminal has a plurality of conductor insertion areas, each with its own actuating part and cutting contact, and the cutting contacts can be electrically contacted via the contact part.
  • an electrical connection made via the contact part can be separated from two cutting contacts by moving one of the cutting contacts into the release position.
  • the electrical connection between electrical conductors in the terminal can thus in particular be separated without one or more of these electrical conductors being removed from the terminal.
  • a rotational movement between the contacting position and the release position can be at an angle of 60 to 120°. This means that the cutting contact can be moved from the release position to the contacting position, or from the contacting position to the release position, by a corresponding rotary movement of the actuating part at an angle of 60 to 120°.
  • the rotational movement is preferably 90° in order to switch between the contacting position and the release position by rotating the actuating part.
  • the operating part may have a lever portion for rotating the operating part about the axis of rotation.
  • the actuating force for severing the insulating material of the electrical conductor can be applied in a particularly simple manner.
  • the lever section In the contacting position, the lever section preferably runs parallel to the insertion direction and optionally parallel to the conductor insertion area. This results in a particularly compact clamp.
  • the actuating part can have a rotary position section which, in the contacting position and/or the release position, forms a stop and/or latching with a corresponding rotary position section. This simplifies the assembly and/or disassembly of the electrical conductor through the terminal.
  • the latching represents a particularly advantageous way of securing the electrical conductor that is electrically contacted in the terminal.
  • the conductor insertion area is preferably surrounded in an electrically insulating manner radially on the circumferential side.
  • the terminal can also have an insulating material housing in which the actuating part is rotatably accommodated.
  • the insulating material housing can have or form the corresponding rotational position section.
  • the insulating housing can be designed in one piece or in several pieces. Above all, the insulating housing offers protection against unwanted electric shocks and/or short circuits.
  • the insulating material consists of plastic.
  • the insulating material housing can have a conductor channel which forms at least part of the conductor insertion area. In the contacting position it can thus be provided, for example, that the cutting edge crosses and/or runs through the conductor insertion channel and/or is immersed in it, in particular more immersed than in the release position.
  • the conductor insertion channel preferably defines the conductor insertion direction. This allows the electrical conductor to be easily inserted into the terminal.
  • the conductor insertion area can be delimited by the insulating material housing and the actuating part, preferably its lever section. This results in a particularly advantageous partitioning off of the conductor insertion area in the contacting position, as a result of which unwanted electrical contacting with the conductor insertion area can be prevented.
  • the actuating lever provides part of the limitation for covering the electrical conductor.
  • the insulating material housing can have a recess (ie a clearance) in such a way that at least part of the cutting contact is provided or moved in the recess while this is moved by means of rotation of the actuating part.
  • the recess preferably extends in such a way that it follows a movement path of the part of the cutting contact upon rotation of the actuating part.
  • a particularly compact and weight-saving clamp can be provided as a result of the recess.
  • the recess is preferably a guide groove.
  • the guide groove is designed in such a way that it guides the at least one part of the cutting contact while it is being moved by rotating the actuating part.
  • the guide groove has the effect, in a particularly advantageous manner, that the cutting contact is accommodated in a defined position in the clamp during the rotation of the actuating part.
  • the guide groove prevents the cutting contact from performing a translatory movement parallel to the axis of rotation.
  • the part of the cutting contact preferably has the contact area.
  • the insulating material housing can have a base in which the recess is formed at least partially.
  • the terminal can be made particularly compact.
  • the recess optionally serves as a guide groove
  • the cutting contact can also be brought into an advantageous position with respect to the conductor insertion area, in which the cutting edge cuts through the insulating material of the electrical conductor at a particularly advantageous angle.
  • the guide groove can be provided in such a way that the actuating forces are increased because, for example, there is sliding friction between the guide groove and the cutting contact.
  • the recess can also be designed in such a way that there is no sliding friction with the cutting contact because, for example, there is a distance between the walls delimiting the recess (side walls, base, etc.) on the one hand and the cutting contact on the other. As a result, the actuating forces can be kept particularly low.
  • the insulating material housing preferably the aforementioned base, can have a bulge in which the recess is at least partially formed. Consequently, material can be saved and the clamp can be made more compact overall, since additional material is only provided at the point in which the recess runs at least partially. This point then forms the bulge.
  • the Figures 1 to 12 show by way of example a preferred embodiment of a clamp 1 according to the invention.
  • the terminal 1 is generally used for the electrical connection of an electrical conductor 2 (flexible or rigid).
  • the terminal 1 can be provided for a first electrical conductor 2 with a further (second) electrical conductor 2, as in the Figures 1 to 5 exemplified to connect;
  • Terminal 1 can also be used to electrically connect more than two electrical conductors.
  • the terminal 1 can be designed or used only for the electrical connection of a single electrical conductor 1, for example for the electrical connection to an electrical load (eg an electrical device).
  • the terminal 1 can be an installation terminal, for example.
  • the electrical conductor 2 usually has insulation or an insulating material, with the insulating material encasing a wire or a conductor core in order to electrically insulate the conductor core and thus serve as protection against accidental contact.
  • the insulating material is made of an electrically insulating material such as a plastic.
  • the conductor core usually consists of a (metallic) wire or several twisted wires. The electrical currents of the electrical conductor 2 are conducted via the conductor core.
  • the terminal 1 is suitable for connecting the electrical conductor 2 without stripping the insulation. This means that the terminal 1 makes it possible for an electrical conductor 2 to be electrically contacted through the terminal by the electrical conductor 2 not being stripped of insulation got to; it is therefore not necessary to remove part of the insulating material along a certain length of the electrical conductor 2 before inserting the electrical conductor 2 into the terminal 1 so that it can be electrically contacted in the terminal 1 .
  • the terminal 1 may include a housing (insulated housing) 10 generally intended to insulate the electrical connection provided by the terminal 1 .
  • the housing 10 is thus designed as an insulating material housing.
  • the housing 10 is preferably made of an insulating material, such as plastic.
  • the housing 10 can be made in several parts and thus have at least or only a first housing part 11 and a second housing part 12 .

  • the housing parts 11, 12 have mutually corresponding connecting elements which are in (corresponding) engagement with one another in order to connect or fasten the housing parts 11, 12 to one another.
  • the connecting elements can be designed, for example, as a snap and/or latching connection, so that the housing part 11 is simply snapped or latched onto the housing part 12 and these are connected to one another or fastened to one another.
  • the invention is not limited to a multi-part design of the housing 10 .

  • the cutting contact 30 is then in electrical contact with the electrical conductor 2, namely via the cutting edge 33. It is preferred if in the contacting position at least or only the cutting edge area 33.1 and/or the cutting edge area 33.2 makes electrical contact with the electrical conductor 2 or its conductor core. If the cutting opening of the cutting contact 30 is present, the electrical conductor 2 is then at least partially provided in the cutting opening in the contacting position.
  • the cutting edge 33 runs along an arc around the axis of rotation, the cutting edge 33 will cut through the insulating material of the electrical conductor 2 during the rotation of the actuating part 50 at an advantageous angle and along a relatively long cutting path. As a result, it is not necessary to apply a large operating force to the operating part 50 in order to cut through the insulating material.
  • the electrical contacting of the electrical conductor 2 is thus simplified by the terminal 1 .
  • the clamp 1 is more compact due to the arcuate cutting edge 33 . It is particularly advantageous if the cutting edge 30 can be moved on a circular path with a defined radius with respect to the axis of rotation by rotating the actuating part 50 . As a result, the actuating forces can be reduced even further.
  • the cutting edge 33 is provided in the contacting position so that it crosses the conductor insertion area 13 . That is, the cutting edge 33 passes through or is immersed in the conductor insertion portion 13 . It can be provided that the cutting edge 33 is immersed more into the conductor insertion area in the contacting position compared to the release position. In the contacting position, the cutting edge 33 therefore does not release the conductor insertion area 13 . If no electrical conductor 2 is introduced into the terminal 1 in the contacting position, as for example in FIG figure 6 shown, it is not possible to introduce an electrical conductor 2 in the terminal 1 for electrical contact. In other words: the electrical conductor 2 or its distal end cannot be inserted further into the terminal 1 than the cutting edge 33 .
  • the terminal 1 can in particular be designed in such a way that in the contacting position the cutting edge 33 crosses or runs through a conductor insertion plane E which is parallel to the conductor insertion direction and to the axis of rotation.
  • the conductor insertion plane E extends horizontally from left to right.
  • the conductor insertion plane E can, for example, be spanned by the one or more conductor insertion directions of the one or more conductor insertion regions 13 .
  • the conductor entry level E can also be a geometric plane, for example a plane of symmetry, of the conductor insertion area 13 .
  • the cutting edge 33 is preferably at a distance from the conductor insertion plane E in the release position.
  • the cutting contact 30 can have a contact section 35 which can be electrically contacted with a contact part 40 .
  • the electrical contact between the contact section 35 and the contact part 40 can be provided by rotating the actuating part 50 .
  • the contact section 35 is in electrical contact with the contact part 40 .
  • the contact section 35 and the contact part 40 are preferably designed in such a way that in the contacting position they engage in one another like a comb and/or in a clamping manner in order to provide the electrical contact. It is preferred if the electrical contact between the contact section 35 and the contact part 40 is only in the contacting position.
  • the contact section 35 is therefore preferably electrically isolated from the contact part 40 .
  • An exemplary position of the contact area 35 relative to the contact part 40 in the release position is shown in FIG figure 3 shown. As the figure 3 can be seen, the contact portion 35 can be spaced in the release position of the contact part 40 and / or detached so that they are electrically isolated from each other.
  • the contact section 35 can be formed in different ways.
  • the contact portion 35 may protrude radially from the cutting contact 30 with a contact area with respect to the axis of rotation. It is preferred if the contact section 35 is formed integrally with the cutting edge 33 .
  • the contact section 35 can be formed by bending and/or stamping, for example from the same sheet metal from which the cutting edge 33 is also provided. As the figure 3 can be recognized by way of example, the contact section 35 can extend from the stop of the cutting contact 30, against which the electrical conductor 2 (or its distal end) abuts in the release position.
  • the contact part 40 can provide different functions. It is preferred if a plurality of cutting contacts 30 can be electrically contacted via the contact part 40 in order to electrically connect these cutting contacts 30 to one another via the contact part 40 . An electrical connection between a first electrical conductor 2 and a second electrical conductor 2 can thus be established via the contact part 40 . This electrical connection can then be easily separated by the actuating part 50 is moved into the release position and thus the contact section 35 is electrically separated from the contact part 40 .
  • the contact part 40 can be provided in the terminal 1 in different ways. As the Figures 3 and 5 can be seen, the contact part 40 can be accommodated in the housing 10, for example. For example, the contact part 40 can be accommodated or arranged at least partially in the upper housing part 11 . It is preferred if the contact part 40 extends from the upper housing part 11 into the lower housing part 12 .
  • the contact part 40 can be connected to the housing 10, preferably in the upper housing part 11, via a force fit and/or form fit.
  • a recess (i.e. exemption) 14 can also be seen, which the terminal 1 can optionally have.
  • the recess 14 can be provided in the form of a groove and is preferably a guide groove 14.
  • the recess 14 or guide groove offers in particular the advantage of securely receiving the cutting contact 30 during the rotation of the same.
  • a defined position of the contact section 35 relative to the contact part 40 can be effected via the guide groove 14 . This ensures that a reliable electrical connection between contact section 35 and contact part 40 can be provided.
  • the recess 14 is formed such that at least a part of the cutting contact 30 (e.g. the contact portion 35) is provided in the recess 14 while the cutting contact 30 is moved by rotation of the operating part 50 .
  • the recess 14 can, for example, extend along a direction that corresponds to the movement path of the part of the cutting contact 30 during the rotation of the actuating part 50 about the axis of rotation.
  • the recess 14 can be formed at least partially in a base, for example in the base provided by the housing base 12 .
  • the housing 10 can have a bulge 15 which is formed, for example, by the bottom of the housing 10 and/or the lower housing part 12 .
  • the recess 14 can be formed at least partially in the bulge 15.
  • the actuating part 50 can be provided in such a way that a rotary movement of the actuating part 50 in an angular range of 60 to 120°, preferably 90°, moves the cutting contact 30 from the release position to the contacting position, or from the contacting position to the release position.
  • the actuating part 50 can have a lever section 51 for simple actuation. In In the contacting position, the lever section 51 then preferably extends parallel to the conductor insertion direction and preferably adjacent to the conductor insertion area 13.
  • the actuating part 50 can serve to limit the conductor insertion area 13 when the cutting contact 30 is moved into the contacting position. In the contacting position, the conductor insertion area 13 can then be limited in particular by the housing 10 and the actuating lever 50, for example by its lever section 51.
  • the actuating part 50 can have a rotary position section 52 which forms a stop and/or a latch in the contacting position with a corresponding rotary position section 16 .
  • the rotary position section 52 can form a stop and/or a latch in the release position with the corresponding rotary position section 16 .
  • the corresponding rotational position section 16 is preferably formed by the housing 10 . It is preferred if the rotary position section 52 is provided on the lever section 51 and/or a distal end of the actuating part 50 or the lever section 51 .
  • the corresponding rotational position section 16 is preferably formed in the upper part 11 of the housing.
