Definitions

  • the invention relates to a connection device for stripping-free Anzapfarra ist a multi-phase flat cable, which makes it possible to tap only one of the wires belonging to the different phases, so make a "phase selection”.
  • Connection devices with which a continuous flat cable with several, lying in a plane power conductors (eg for 380V three-phase) can be tapped without separation of the wires and without removal of wire and cable insulation, have been known for over 30 years.
  • An early publication in this respect from the applicant's home is, for example, the German patent application DE-AS 2 206 187 .
  • Tapped screws are used as tapping contacts.
  • the connection is made by the connecting device with its housing - initially without the contact screws - placed on the cable and then the cable is also enclosed on the back of a housing plate.
  • the tap is done by the guided in the housing with internal threads contact screws are screwed into the flat cable. They penetrate with their tip, first the outer insulation of the flat cable, then the respective core insulation, and finally penetrate with the tip in the head of each vein. This contacts the relevant wire.
  • a three-phase load must be connected to all three phase conductors; Single-phase consumers, however, are only connected to a phase conductor (and the neutral conductor as a return conductor).
  • the various single-phase loads of a consumer unit e.g., a building
  • the three phase conductors with approximately equal distribution.
  • connection devices each type each allowing connection to a specific phase conductor.
  • a connection device is desirable in which the tapable wire is not fixed, but which allows the installer, the desired phase conductor only during installation to choose by a corresponding adjustment of the device.
  • phase core the conductor forming a phase conductor
  • a contact slide is provided as a phase selector. This can be moved linearly to select the desired phase across the cable (at a 90 ° angle or slightly inclined to the cable longitudinal direction) (see eg WO 00/41277 . DE 196 15 597 . DE 197 46 493 . DE 41 27 899 ).
  • a second known type has the phase selection, however, a bridge-like arm (see, eg DE 199 43 734 and DE 38 18 078 ).
  • connection devices are partly structurally relatively expensive.
  • the aim of the present invention is to provide a connection device with phase selection that has been further developed in this regard and also with regard to safety.
  • the connecting device according to the invention for stripping-free Anzapfffy ist a multiphase flat cable has a rotatable phase selector which allows contacting only one of the phase conductors of the flat cable with a tap contact in certain rotational positions.
  • the phase selector is locked in making the phase selection regarding the phase selection made.
  • the lock is non-destructive non-releasable. Nevertheless, the connection device after making the selected phase non-destructive separable from the flat cable, so that it is reusable with the phase once selected.
  • connection device having a rotatable phase selector which allows contacting only in certain rotational positions of a phase conductor of a flat cable with a tap contact.
  • the connection device is connected to the flat cable, with a phase selection is taken and the phase selector is arrested non-destructively nondestructive with respect to the selected phase selection in the connection device.
  • it is then separated from the flat cable nondestructively and reused while maintaining the once selected phase at another point of the flat cable of the same strand or on another flat cable harness.
  • the terminal device is designed to permit the tapping of a continuous flat cable having a plurality of in-line power cores (e.g., for 380V three-phase) without separation of the cores and without the removal of wire and cable insulation.
  • tapped screws can serve as tapping contacts, for example.
  • the preparation of a connection then takes place, for example, by the fact that the contact screw is screwed into the flat cable. It penetrates with its tip, first the outer insulation of the flat cable, then the core insulation of the selected phase core, and finally penetrates with the tip in the head of the selected phase core and contacted them hereby.
  • the terminal device thus permits on-site phase selection (i.e., at the point of manufacture of the terminal) by means of the rotatable phase selector. It is designed so that the flat cable to be tapped can be contacted only in certain rotational positions of the phase selector with a tap contact. To select a phase, the phase selector is thus brought into one of these predetermined rotational positions. In the course of the phase selection, ie after rotation in one of the above positions, it is locked. The lock ensures that the phase selector does not come off the selected position again. It is thus also secured in particular with regard to the selected phase selection.
  • the lock is non-destructive non-solvable, so that the once made phase selection is non-destructive non-reversible. That is, for example, that the phase selector can not be taken out of the recording after making the phase selection, without the connection device thereby destroyed (ie significantly impaired in terms of their functionality or rendered useless).
  • the locking is done by means of a latch.
  • a detent undercut arrangement is self-locking, so that the catch in the forcibly pulling out the phase selector breaks and thus in a possible attempt to use it again in the recording, the locking function is no longer available.
  • the bolt can not be designed to be openable, so that it breaks when violently open, and no longer works for a new lock.
  • connection device is not unusable once the phase has been selected and the phase selector has been locked. Rather, the connection device can also be removed after making the selected phase non-destructively from the flat cable and, for example, at another offset in the longitudinal direction of the same Flachiquesstrangs or other flat harness - while retaining the already made phase selection - be reused.
  • the phase-selection element has a tapping device, for example.
  • tapping device is used here as a generic term for various possibilities of embodiment.
  • the tapping device can be designed, for example, as a guide for a tapping contact that is movable in the tapping direction, into which the tapping contact has already been inserted and only has to be moved in to tap the flat cable. It is also conceivable that the tapping contact is not yet inserted into the guide, so that the guide alone forms the tapping device. Furthermore, the tapping device can also be designed as a tapping contact fixed in the tapping direction or as a loading element for a tapping contact. As in tapping movable tapping For example, rotatable contact screws may be used. The actual Anzapf chunk ist takes place after the phase selection, in which the phase selector was irreversibly locked by screwing in the contact screw.
  • connection device can be removed after unscrewing the contact screw again from the flat cable and attached at another point in the cable longitudinal direction again on this or on another harness. In order to contact the same phase conductor again at this new position, it is only necessary to re-screw in the contact screw (no further phase selection).
  • the inventors of the present invention have recognized that only one possible phase selection in connection devices in which a tapping operation only ever contacts one of the phase conductors of the flat cable (i.e., only the insulation of one of the phase conductors is pierced) results in an increase in safety. Because a multiple phase selection at the same point of a flat cable leads to relatively little spaced apart injuries of the protective insulation of different phase conductors. As a result, for example, the occurrence of short circuits due to the small creepage distance between the exposed contact points would not be excluded.
  • connection device according to the invention is relatively simple in terms of construction, while the aforementioned prior art connectors are structurally rather complicated with pivoting jumpers or fork contacts; In addition, with them all the phase wire - even the ultimately unselected - tapped with a tap, while in the present connection device only the wire of the selected phase conductor needs to be tapped; i.e. there is only a puncture of the isolation of one, namely the actually selected phase core.
  • a receptacle for the phase selector member is provided, which is formed complementary to the phase selector.
  • the locking then takes place, for example, by pressing down the phase selector and a lock in the recording.
  • a catch undercut arrangement may be provided on the phase selector member and the receiver, which initially deforms elastically upon insertion of the phase selector member into the phase selection recess of the receiver and then locks into place.
  • a tapping device is arranged eccentrically to the axis of rotation of the phase selector.
  • the "rotation axis" may be the imaginary axis around which the phase selector member is to be rotated to reach the various phase selection positions, or a structural axis with which the phase selector member is mounted on the receiver. Due to the eccentric arrangement of the tapping device to the axis of rotation of the phase selector, the rotation of the phase selector leads to a movement of the tapping device along a circular path about the axis of rotation, and thus to the necessary offset transversely to the cable longitudinal direction to contact the desired phase core.
  • the eccentricity ie the distance of the tapping device from the axis of rotation, is selected such that said circular path at least approaches the selectable phase core (or cores) furthest from the axis of rotation.
  • the axis of rotation is arranged, for example, over the middle phase core.
  • the eccentricity has at least the size of the distance between the middle phase conductor and the most distant phase conductor.
  • the complementary design of phase select element and receiving a 120 ° symmetry follows. This is such that the receptacle can accommodate the phase selector only in exactly three rotational positions, which are angularly spaced apart by 120 °. Thus, it is possible only in one of these three rotational positions, for example, press down the phase selector in the recording and thus make a phase selection.
  • Said 120 ° symmetry relates functionally to the ability of the phase selector to be placed in a position which allows the tapping contact to penetrate into the flat cable.
  • the outer shape of the phase selector and / or receiver can - unless it is decisive for this function - deviate from the 120 ° symmetry.
  • one of the corners of the triangle could be cut off in the case of the complementary phase selection element.
  • the 120 ° symmetry would be broken in view of the missing corner. Since, however, the said function would also be ensured with the cut-off corner, the phase-selection element can be brought into contacting position only in one of the three angular positions spaced apart by 120 °, the 120 ° symmetry is safeguarded in the functional sense on which it is based.
  • phase selector and the pickup which do not directly affect their interaction, do not refer to the 120 ° symmetric design.
  • a handle for example a type of twist grip
  • a handle which does not have a 120 ° symmetry can be formed on the phase-selection element.
  • the selectable for contacting phase conductors equally spaced. It is namely a property of the 120 ° symmetry that, in an arrangement of the phase selector, wherein the axis of rotation is disposed over the middle of the three selectable phase conductors and in one of the three selectable angular positions of the eccentric contact on the middle phase core, the contact in the two other possible angular positions come to lie at the same distance left or right of the center line (namely, the three contact positions lie on the corners of an equilateral triangle).
  • the 120 ° symmetry of the fully (ie by 360 °) rotatable phase selector thus forms the geometric equivalent of the equal spacing of the phase conductors in the cable.
  • a flat cable of the type mentioned are, for example, from the document mentioned above DE-AS 2 206 187 known.
  • the connecting device may be in the eccentrically arranged on the phase selector tap device, for example, a guide for a Tapping and the tapping itself act, the tapping - as will be explained in more detail below - is designed to be movable in the direction of the cable core (eg, in the manner of a screw-in contact screw).
  • the connection device is therefore already supplied, for example, with the tapping contact inserted into the guide, so that the installer no longer has to insert the tapping contact into the guide in a separate operation during its installation. So that the tapping contact - for example, during transport of the connecting device or during their installation - does not fall out of the guide, this can be provided for a loss-protection.
  • a loss protection such as, for example, a closable cover of the guide or another releasable holder.
  • the tap contact does not necessarily have to be inserted in the eccentrically arranged tapping device, but it may also be provided only the guide.
  • the tap means the phase selection would still be performed by rotation of the phase selector without applied tap contact, and only in the next step, the tap contact would be used (eg, the contact screw inserted into the guide).
  • the connection device is therefore supplied here, for example, without tapping contact, so that the latter is inserted into the guide at a later time (eg as part of the installation). This can be useful, for example, if the connection device is prepared for different types of tapping contacts and initially should remain open, which type should actually be used.
  • the tapping device can also be designed as a tapping contact which is fixed in the tapping direction, in which case no guide has to be provided for it.
  • a tapping contact in "waiting position" is present in the connecting device for each tappable phase. After phase selection (i.e., rotation of the phase selector to the respective angular position), only the tap contact associated with the selected phase conductor is pressed into the cable by applying an eccentric load to the phase selector so that only the selected phase wire is also contacted.
  • the applying element is e.g. around a guided in the phase selector ram.
  • the restriction of the tapping on the only three said angular positions is achieved in that the receptacle is formed as a recess, and the phase selector can be inserted into the recess only in the three allowed by the 120 ° symmetry rotational positions.
  • the recess and the phase selector may be substantially in the shape of an isosceles triangle oriented relative to the flat cable such that the projection of one of its bisectors perpendicular to the cable coincides with the middle one of the three phase conductors.
  • the fact that in this case only one of the phase cores can be contacted, is based on the fact that the phase selector has only one tapping device.
  • the possibility for the penetration of the tap contact is limited to the three said rotational positions, that the receptacle has three passage openings for the tap contact in 120 ° symmetry.
  • These can be configured for example as threaded holes and allow the passage of the tap contact to the flat cable and thus the contacting of the selected phase core only in one of the three rotational positions.
  • This measure can be provided in embodiments with recording in the form of a 120 ° -symmetric recess (as stated above); but it is possible that the 120 ° -symmetrical arrangement of the passages mentioned here alone ensures that the tap can only take place in one of the three said rotational positions.
  • the part of the phase selection element that is complementary to the receptacle is mainly designed as a rotatable plate which is oriented perpendicular to the axis of rotation.
  • the axis of rotation may be an imaginary axis.
  • the installer would in this case rotate the phase selector "free-flying" to the angular position corresponding to the desired phase and insert it in this position in the receptacle.
  • the axis of rotation is structurally defined. It is in embodiments in which the phase selector can be inserted into the receptacle, an axially displaceable pivot bearing.
  • an axially displaceable stub axle stub bearing arrangement is provided between the phase selector and the receptacle.
  • the stub axle at the bottom of the receptacle may be arranged directed in the center of the phase selector; the bearing for this axle stub e.g. in the form of a complementary to the stub shaft hole with sufficient length for the axial displacement is then found in the phase selector.
  • the phase selector is equipped with the stub axle; in the bottom of the receptacle is then found e.g. a bore forming the bearing.
  • connection device for defining the axis of rotation of the phase selector element on a circular recess This leads the phase selector rotatably on the recording.
  • the inner radius of the circular recess preferably corresponds to the largest radial extent of the cooperating with the depression portion of the phase selector (ie in a phase selector in the form of an equilateral triangle, for example, the distance of the corners of the triangle from the fulcrum).
  • Such causes an axis definition, analogous to the stub axle stub bearing arrangement.
  • the circular recess but facilitates the management of the phase selector element over the recording during the rotary movement.
  • a handle is provided on the phase selector. This makes it easier for the installer to turn the phase selector and, if necessary, to insert it into the receptacle.
  • the handle in each of the three possible rotational positions on a mark that identifies the phase in question. From this, the respectively selectable or already selected phase can be read, which helps to avoid confusion in the phase selection or to check the phase selection made.
  • the handle may have a shape that is pronounced of a pointer (or may have a pointer icon attached to it). The pointer points depending on the rotational position of the phase selector element on the relevant phase marker.

  • the thread of the screw gets in her screwing in contact with the likewise electrically conductive internal thread of the respective passage opening.
  • the internal threads of the openings in turn are electrically connected, for example, with a leading through the connecting device connecting web.
  • the connecting bridge provides for the current transfer, for example, to an outlet connection on the housing of the connecting device.
  • the internal thread of the passage opening also absorbs the reaction force, which opposes the flat cable Anzapttag when screwing it in.
  • the stub axle stub bearing arrangement is formed as a rotary electrical connection, so that the Electricity transfer from the rotatable phase selector to an outgoing connection.
  • the reaction force that opposes the flat cable the tapping when pressing or screwing, can be added in this variant by the latch.
  • connection device In a configuration with contact screw, there are various possibilities for the order of the individual operations during installation of the connection device. For example, first of all the connecting device can be placed on the flat cable to be tapped on the point of the flat cable provided for the connection. Then the installer can make the phase selection by rotation of the phase selector, pushing in and possibly locking in the recording. The order of these two steps can also be reversed. In general, only then the contact screw is screwed in and thus tapped the selected phase wire. Because if the phase selector is already in its final position immediately above the phase core, the contact screw is well managed and therefore will hit the core exactly in the middle. The tapping of the flat cable is thus decoupled from the phase selection.
  • the contact screw When uninstalling the connection device, the contact screw can then first be unscrewed and then the connection device can be removed from the flat cable. As already mentioned above, the connection device can be placed on another point of the flat cable of the same strand or another flat cable strand again and screwed the contact screw while maintaining the once selected phase again for tapping.

  • the phase selector 2 and the receptacle 4 are shaped complementary to each other in 120 ° symmetry. This symmetry requires that the phase selector 2 can be pressed down in exactly three rotational positions in the recording 4 for the purpose of phase selection.

  • the phase selector 2 is currently in an angular position between two “allowed” positions, and therefore can not be pressed into the receptacle 4 there (because the cut corners of the phase selector 2 are not over the corresponding corners of the receptacle 4).
  • Fig. 7 shows the corresponding end position of the contact screw.
  • a circular recess 14 relative to the surrounding level of the housing bottom.
  • the cut corners of the phase selector 2 are complementarily rounded thereto.
  • the recess 14 forms a guide surface, which facilitates the rotation of the phase selector element 2 and reaching the permitted angular positions.
  • the actual 120 ° -symmetric recording 4 lies in the bottom of the recess 14th
  • the receptacle 4 has recesses 15 on its leg portions.
  • the locking lugs 6 are barb-shaped in cross section in this second embodiment.
  • the receptacle 4 recesses 10, each having a nose-shaped projection ( Fig. 11 ).
  • the latching lugs 6 When the phase selection element 2 is pressed in, the latching lugs 6 enter into it with elastic deformation and are guided along the wall of the receptacle 4 along their legs. In this case, the angle between the surfaces of the deformable locking lugs 6 and the wall of the receptacle 4 in turn is relatively acute, so that the engagement surfaces slide past each other.
  • the latching hooks 6 snap into the recesses 10 and underpin the projection ( Fig. 12 ).
  • phase-locked member 2 latched in this way is likewise not removable from the receptacle 4 in a non-destructive manner.
  • the hook-shaped detent 6 breaks off ( Fig. 13 ). A new phase selection is thereby avoided.
