Definitions

  • the invention relates to a multiphase clamping device for connecting the conductors of a main cable to the conductors of a branch cable with clamps which have contact pieces which are held together with screws and between which the conductor of the main cable and the conductor of the branch cable are clamped, the contact pieces for two Phases lie in a plane perpendicular to the cable axis.
  • Multi-phase clamping devices of this type are known in various designs and are used, for example, to connect so-called branch cables to a main cable laid in the ground, which are used, for example, for a so-called house connection.
  • Such connection connections must be possible without cutting the main cable, without interrupting the power supply and without stripping the individual conductors of the main cable.
  • the corresponding claims work can be carried out so that on the one hand reliable connections are made and on the other hand the fitter cannot come into contact with live parts for safety reasons.
  • Another requirement is that the security of the connections made in this way must be reliably guaranteed for very long periods of many years.
  • each housing half accommodates a group of two phase conductors and two branch conductors.
  • the two halves of the housing are connected with two screws. These two screws pull the two housing halves against each other, with corresponding teeth on the contact pieces penetrating the insulation of the phase conductor or the neutral conductor and ensuring the electrical connection from the wires of the main cable to the assigned wires of the branch cable.
  • a branch terminal of this type may be suitable for a number of purposes, but assembly is very tedious and time-consuming, since a total of six screws have to be tightened in order to make all the connections. It should not be disregarded that the corresponding screws for clamping are not freely accessible during installation, because at least two screws must be tightened from the underside due to the stiffness of the cables with the required cable cross-sections. It should be noted that the cable trenches that are opened for this purpose only have a small width of about 80 cm, so that the fitter has little room for movement in the cable trench. Under such conditions, the assembly of the branch terminal is associated with considerable difficulties because the tool has to be used very often. Unless the connection is carried out with great care and a correspondingly high expenditure of time, the security of the connections cannot be guaranteed.
  • a multi-phase clamping device of the type mentioned is known from DE-PS 20 62 304.
  • this conventional design has several shortcomings.
  • This known clamping device namely has a large number of individual parts, which complicates both the manufacture and the assembly of the clamping device.
  • the invention is therefore based on the object of specifying a multiphase clamping device of the type mentioned at the outset, which manages with a small number of components and nevertheless enables simple assembly and reliable contacting of the conductors.
  • the solution according to the invention consists in forming a multi-phase clamping device of the generic type in such a way that a pair of contact pieces is provided for a pair of conductors of the main cable and a pair of conductors of the branch cable, between which there is a toothed wedge made of insulating material as a counter-bearing for the respective Conductor is located, and that the screw for holding the pair of contact pieces with pressure pieces in the contact pieces is stored and insulated.
  • the object is achieved in a satisfactory manner with the device according to the invention.
  • the insulating plastic parts can be produced in a cost-effective manner as injection molded parts, even if these plastic parts have a complex shape. Due to the Arrangement of the components in pairs can each be the same, so that the number of different parts is small. To connect the main cable and connection cable with four conductors each, only two clamping screws are required, which are tightened completely independently of one another.
  • each contact piece is designed as a rocking part which has cutting edges on its front edge for engagement with the conductors, which are designed for engagement in the longitudinal direction with the conductors of the cables.
  • the contact piece has a single contact tooth for contacting a conductor of the main cable and a contact comb for contacting a conductor of the branch cable. In this way, a plurality of conductors with different cross sections can be contacted using the same contact pieces.
  • the surfaces of the contact tooth for the conductor of the main cable enclose an angle of the order of 30 ° to 40 ° and that the lower edges of the teeth of the contact comb lie in a plane which is one with the horizontal Includes angles on the order of 10 °, such that the contact comb opens outwards away from the screw.
  • such a design ensures perfect contacting by means of the cutting edges penetrating the conductor insulation.
  • the contact piece has an outer stop bar for positioning and stabilizing a conductor of the main cable.
  • the respective conductor of the main cable is gripped laterally so that the cutting edge can be reliably pressed through the insulation of the conductor when the screw is tightened and brought into close contact with the conductor.
  • one arm of the contact piece merges angularly into the stop bar, its outer contour being drawn inward in an arc towards the screw. This measure also helps to improve the positioning and stabilization of the conductor in the contact piece. At the same time, the rotational mobility of the contact piece designed as a rocking part is improved.
  • the contact piece on its rear side facing away from the conductors has a continuous trough running in the longitudinal direction of the conductor for receiving the respective pressure piece and that a through hole is provided in the contact piece transversely to the trough, which has a limited pivoting movement of the Contact piece transverse to the axis of the screw allows. In this way, a suitable mutual positioning of the contact piece and pressure piece is achieved and the attachment of the clamping device to a cable is facilitated.
  • the respective pressure piece can expediently be inserted into the associated contact piece non-rotatably about its longitudinal axis. It is particularly advantageous if, in the device according to the invention, the pressure piece has a body with a cylindrical cross section, in which the head of the screw or the associated one Screw nut is receivable. A favorable assignment of contact piece and pressure piece is achieved and a low overall height of the device is achieved.
  • the pressure piece has recesses in its body with which a screw nut can be non-rotatably positioned.
  • a screw nut can be non-rotatably positioned.
  • the pressure piece has a hollow shaft which passes through the contact piece and insulates and guides the screw in its interior. This further improves the mutual positioning of the individual parts of the clamping device without increasing the number of individual parts.
  • the hollow shaft of the pressure piece has at least one radially inwardly protruding knob which simulates a thread for engagement with the thread of the screw.
  • the hollow shaft of the pressure piece has beveled areas at its outer end which extend only over part of its circumference and form guide surfaces. In this way, a perfect positioning of a corresponding counterpart can be achieved.
  • the pressure piece has recesses on the outside of its body, in which a protective cap can be fastened. Such recesses can be provided in one step in the manufacture of the pressure piece.
  • the toothed wedge has a plurality of sharp-edged teeth for penetrating the insulation of the conductors, which extend transversely to the longitudinal axis of the conductors. These teeth ensure a perfect penetration of the insulation and a correspondingly reliable positioning of the conductor between the tooth wedge and the contact piece when the screw has been tightened.
  • the teeth for engagement with the conductors of the branch cable form a trough-shaped conductor bed for positioning these conductors. Regardless of the cross-section of the conductors of the branch cable, this ensures that these conductors are correctly positioned and contacted.
  • the trough-shaped conductor bed has lateral limiting webs running in the longitudinal direction of the conductors, these measures also contribute to supporting the positioning of the conductors.
  • the toothed wedge has a wedge-shaped tip at its front end and one at its rear end Striking surface, which may optionally be designed to facilitate driving the spline between a pair of conductors of the main cable.
  • the toothed wedge is designed as a flat plate and is designed with a through hole for the screw. This simplifies the assembly of the toothed wedge. If a preassembled duplicate, which has a pair of contact pieces and pressure pieces and is provided with the screw passing through the toothed wedge, is used, this can be brought into its desired position by driving in the toothed wedge.
  • an insulating spacer is provided between the pair of contact pieces and pressure pieces. This measure helps to keep the components mentioned in a spaced position in order to facilitate the attachment of the clamping device to the cable to be contacted.
  • the spacer is expediently cylindrical and takes up the screw in its interior. This results in a compact and easy-to-assemble arrangement.
  • the toothed wedge has cylindrical shell-shaped walls which are spaced apart in the circumferential direction and extend outwards perpendicularly from its main plane and form the spacer. This reduces the number of components required and at the same time ensures that the contact pieces are correctly positioned.
  • the spacer has beveled end edges at its outer ends for correct positioning. These end edges expediently interact with correspondingly shaped areas on the shaft of the pressure piece.
  • toothed wedge of the device according to the invention is symmetrical with respect to its main plane is particularly advantageous.
  • Such components are particularly easy to manufacture and can be installed in any orientation.
  • a single insulating spacer wedge each associated with two pairs of contact pieces, is provided, which is designed as a plate and has guide ribs projecting outwards at its outer longitudinal edges transversely to the plate.
  • This spacer wedge ensures, on the one hand, that the conductors of the main cable are correctly positioned separately and, at the same time, that the contact pieces are guided appropriately when they are pulled against one another by the screw for contacting the conductors.
  • the spacer wedge is designed as a thin-walled plate and can be flexibly bent. Even if the individual conductors of a cable have a certain twist, the spacer wedge can easily be inserted between them.
  • the spacer wedge has a wedge-shaped tip at its front end and a striking surface at its rear end, which is optionally curved. In this way, the insulating spacer wedge can be used in a simple and reliable manner.
  • the conductors 15 and 16 of the branch cable can be inserted from the side and inserted into a trough-shaped bed 63 of the toothed wedge 60 without the insulation of these conductors needing to be removed. Since the contact pieces 30 are designed as rocker parts, they can be pivoted transversely to the screw 70, so that there is sufficient space for the introduction of the conductors 15 and 16. This lateral insertion of the conductors of the branch cable considerably simplifies assembly.
  • the two conductors 14 and 17 of the branch cable have both been inserted into the corresponding trough-shaped bed of the toothed wedge 60.
  • the screw 70 is already partially tightened such that the distance between the pair of contact pieces 30 has been reduced and the screw 70 has been screwed into the nut 75.
  • a screw 70 with a cylindrical head 72 with an inner edge 73 is expediently used, since this head 72 can then be easily accommodated in the interior of the pressure piece 50.
  • a spacer wedge 20 is inserted in a central plane and separates the conductors 10 to 13 of the main cable into two groups with the conductors 11 and 12 on the one hand and 10 and 13 on the other.
  • the two toothed wedges 60 are driven in from opposite sides and separate the two conductors 11 and 12 or 10 and 13 from one another. The lateral driving of the toothed wedges 60 is limited by the spacer wedge 20.
  • FIG. 2 shows the situation after the screws have been tightened, specifically for conductors 15 and 16 on the one hand and conductors 14 and 17 on the other hand, which have both different cross-sectional shapes and cross-sectional diameters.
  • the teeth of the contact pieces 30 have penetrated the outer insulation of the conductors 10 to 13 and 14 to 17 and are in mechanical and electrically conductive engagement with the schematically indicated conductor core.
  • the conductors 10 to 13 are held on the outside with stop strips 34 by the contact pieces 30, so that these conductors 10 to 13 cannot avoid when the screw 70 is tightened and screwed into the nut 75.
  • a contact comb interacts with the trough-shaped bed in the tooth wedge 60 to mechanically and the respective conductors 14 to 17 of the branch cable to clamp electrically.
  • the swiveling of the contact piece 30 can be seen in the left-hand area of FIG. 2 in order to ensure reliable clamping in the most varied cross-sections of the conductors of the branch cable.
  • K denotes a circle which denotes the inner circumference of a standard sleeve which is used for such cable branches in order to form a tight seal using cast resin after the clamping connections have been made. It can be seen that such a standard sleeve can also be used in the case of conductors 14 and 17 with very small cross sections, because the screw 70 projects from the screw nut 75 with its thread 74 in a permissible range.
  • FIG. 3 A preassembled module with a so-called duplicate of contact pieces 30 and pressure pieces 50 as well as with screw 70 and toothed wedge 60 is shown in FIG. 3.
  • the contact piece 30 is explained in connection with FIGS. 4 to 6. Details of the pressure piece 50 can be found in FIGS. 7 to 10.
  • the toothed wedge 60 is shown in FIGS. 11 to 17. 18 to 20 show the spacer wedge 20 in its details.
  • the contact piece 30 is designed as a rocker part and has a first arm 36 which merges angularly into a stop bar 34 and, with its outer contour, is drawn inward in an arc toward the screw 70. Its outer end 35 is drawn further inwards than an apex 37, as can be seen in FIG. 6. Between the stop bar 34 and an inner wall 43 there is a single cutting edge 31, the side surfaces 32 and 33 of which form an angle of the order of 30 ° to 40 °. The cutting edge 31 is in the longitudinal direction of the Seen screw 70, much shorter than the stop bar 34th
  • the contact piece 30 On the opposite side, the contact piece 30 has a second arm 44, which has a plurality of cutting edges 39 on its underside, which form a contact comb 38.
  • a trough 40 is formed on the rear side of the contact piece 30, which advantageously has a cylindrical cross section and ends on a web 41 on the side of the contact comb 38.
  • the lower edges of the teeth 39 of the contact comb 38 lie in a plane E which includes an angle of the order of 10 ° with the horizontal H , so that the contact comb 38 opens outward from the screw 70 .
  • the contact piece 30 is penetrated between the two arms 36 and 34 by a vertical through bore 42, the axis of which is offset relative to the longitudinal axis of the screw 70 to the contact comb 38.
  • the through hole 42 is dimensioned so that its cross section is significantly larger than that of the screw 70.
  • an elongated hole can also be provided, but this is generally more difficult and expensive to manufacture.
  • the cutting edges 31 and 39, the stop bar 34 and the web 41 extend continuously in the longitudinal direction, which corresponds to the longitudinal direction of the respective conductor.
  • the contact pieces 30 need not be manufactured as individual contact pieces, but can be made from a suitable dimensioned rail from a suitable one Alloy can be cut off. In these sections, only the through hole 42 is then made.
  • the dimensioning of the contact piece 30 is such that the stop bar 34 is significantly longer than the individual cutting edge 31. This ensures that when the screw 70 is tightened, the conductor to be contacted is first reliably detected and positioned by the stop bar 34 before the contact piece 30 with its cutting edge 31 penetrates the insulation of the conductor and then with the conductor core when the screw 70 is further tightened comes into mechanical and electrical interference.
  • the respective contact piece 30 cooperates on its rear side with a corresponding pressure piece 50, which is inserted into the trough 40 and has a complementary round cross section, which is expediently cylindrical.
  • a corresponding pressure piece 50 which is inserted into the trough 40 and has a complementary round cross section, which is expediently cylindrical.
  • Other round trough shapes can also be used, however, a particularly good and uniform mutual guidance between the contact piece 30 and the pressure piece 50 is achieved with a cylindrical shape.
  • the pressure piece can be inserted non-rotatably about its longitudinal axis into the associated contact piece 30, although, as can be seen from FIG. 3, a relative pivoting movement is provided between the pressure piece 50 and the contact piece 30.
  • the pressure piece 50 thus has a body 51 with a cylindrical cross section, in which the head of the screw 70 or a screw nut 75 assigned to the screw 70 can be received.
  • a nut 75 is indicated schematically in FIG. 7.
  • the body 51 is formed with corresponding recesses 56 in which the screw nut 75 can be positioned non-rotatably.
  • the recesses 56 can also be adapted to other nuts 75 with different external cross sections.
  • FIG. 8 shows a section through the contact piece 50 in a plane which is rotated by 90 ° to the plane of FIG. 7.

  • FIG. 10 The top view of the pressure piece 50 according to FIGS. 7 and 8 from below is shown in FIG. 10. It can be seen that the shaft 52 has opposite areas F with chamfers 57, between which there are areas W in which the shaft 52 is of blunt design according to FIG. 7.
  • the chamfers 57 which only extend over part of the circumference of the shaft 52, form guide surfaces for an opposite component.

Rather, the conductors 14 to 17 of the branch cable can be inserted into the clamping device from the side, as is indicated schematically in FIG. 1. If these conductors have then taken the appropriate position, these conductors of the branch cable can be easily cut to the desired length before tightening the clamping device, since the branch cable is not yet under tension in this state.
