Definitions

  • the invention relates to a clamp according to the preamble of claim 1 and a sleeve with such a clamp according to the preamble of claim 6 and is based on EP-Ai-0 021 550.
  • An insulating plate is also arranged in a known terminal of the type mentioned at the outset (EP-A-0 021-550) in the plane defined by the parting plane of the associated sleeve between the insulated wires, although the contact body of this terminal is a receptacle for the wires to be contacted have serving mouth, which has at least in the area of its one mouth flank to penetrate a wire insulation made of plastic and to be able to contact the wire penetrating element. Not only because of the insulating plate to be inserted between the wires, the section of the cable on which this must be stripped is also relatively long.
  • the cable consists of four insulated cores
  • two terminals arranged in the longitudinal direction at a distance from one another in the sleeve are required because only two cores can be contacted with each terminal.
  • the wires are contacted after the two-part sleeve housing is closed, which is provided with openings from which an electrically insulating bolt first looks out, the longitudinal axis of which is perpendicular to the plane defined by the insulating plate and which is connected to the contact body at the end facing the insulating plate is which is slidably guided in the longitudinal direction of the bolt in the terminal body and the mouth of which is open towards the plate and aligned with the associated wire.
  • the bolt is driven against the insulating plate with a hammer, the mouth picking up and making contact with the assigned wire.
  • the conductor to be connected is contacted.
  • the invention has for its object to provide a clamp of the type mentioned, for its attachment to the cable this must be sheathed on a shorter length than in the known terminals.
  • the clamp according to the invention therefore allows the use of smaller and therefore cheaper sleeves, which also leads to a considerable saving in the resin required for pouring the sleeve. Due to the significantly lower resin requirement, it is possible to use a higher quality resin, which leads to a better seal against the penetration of moisture.
  • the clamp according to the invention is significantly less sensitive to the ingress of moisture, because much longer creepage distances can be achieved without increasing the dimensions of the clamp. This is possible due to the more favorable position of the points in relation to the length of the creepage distance where the wire insulation has to be penetrated.
  • the mouth is preferably designed to be elastically expandable in order to ensure that a sufficiently high contact pressure is maintained.
  • the elastic deformability required for this can be provided by the contact body, provided that it forms the entire jaw including both jaw flanks. In those cases in which the contact body forms only a part of the mouth and in particular only a single mouth flank, the elastic deformability need not only have the contact body. In this case, other parts of the clamp, for example the clamp body supporting the two jaw flanks, are also possible.
  • the other jaw flank with its element or elements for penetrating the wire insulation consists of an electrically insulating material.
  • This elec Trisch isolating mouth flank can be integrally formed with the terminal body or a part thereof.
  • Claims 6 to 13 relate to a sleeve with a clamp, in which not only by the design of the clamp. but also by the design of the sleeve housing in addition to a simple assembly, a space-saving design can be achieved in order to reduce costs.
  • the sleeve housing could surround the clamp and a cable section adjoining it on both sides at a distance, as is the case with the known sleeves, but because of the much shorter piece of cable on which the wires of the cable must be exposed in order to attach the clamp can, nevertheless, a considerable space saving compared to the known sleeves and thus a reduction in the costs for the sleeve housing and the cast resin to be filled in this would be achieved.
  • the exemplary embodiment shown in FIGS. 1 to 3 is a connecting terminal for connecting a branch conductor 1 to each of the conductors 2 of a four-conductor cable in a power supply network.
  • the cable sheath 4 In order to be able to assemble the clamp, the cable sheath 4 must be removed over a length which is somewhat greater than the length of the clamp, but is considerably shorter than in the known connecting clamp for such cables.
  • the connecting clamp has two clamp body parts 5 of the same design, which consist of an electrically insulating plastic and together form the ring-like, centrally split clamp body.
  • the continuous from one to the other flat end face 6 of the terminal body is formed by a semi-cylindrical groove 7 and its diameter is adapted to the diameter of the cable without a cable sheath, as can be seen in FIG. 3.
  • a pressure is not exerted on the insulation 3 of the conductors 2 by the wall of the semi-cylindrical grooves 7 when the two clamp body parts 5 are pulled onto a block, that is to say with their flat side 8 facing the other clamp body part 5.
  • a thin insulating material wedge projects into the two channels 7 and penetrates between the wires to be received by the assigned channel and is formed in one piece with the clamp body part forming the channel.
  • Fig. 2 shows, at the same distance from the two flat end faces 6.
  • the head of the clamping screws 9 and the nuts in which the clamping screws engage are recessed in the clamp body part 5, but are accessible from the cylinder-like outside 10 of the clamp body part.
  • the two clamp body parts 5 are provided with two pocket-like depressions 11 which are open to the side 8 and to the groove 7 and are delimited to the two flat end faces 6 by walls 12 which are parallel to these.
  • the depressions 11 are delimited by a cylindrically curved contact surface 13 which, on the one hand, extends to the channel 7 and, on the other hand, adjoins a flat delimitation surface 14.
  • the clamp body part 5 is provided with an opening 15, which enables access from the outside 10 to the recess 11.
  • the two clamp bodies 5 are each provided with two channels which run parallel to the channel formed by the channels 7 and which open into the recesses 11 and serve to receive one of the branch conductors 1 each.
  • the depressions 11 are offset from one another in the longitudinal direction of the channel 7, namely by an amount which is greater than the sum of the length of the depression 11 measured in the axial direction and the diameter of the bores receiving the tensioning screws 9.
  • the middle zone of the clamp body parts 5, which is free from the depressions 11 and contains the bores for the tensioning screws 9, is approximately as long as the axial length of one of the depressions 11.
  • the two depressions 11 are also shown in FIG. 1 , offset in the circumferential direction of the channel 7 to such an extent that both adjoin the longitudinal center plane of the clamp body part 5 which is perpendicular to the side 8.
  • each of the depressions 11 there is a contact body 16 made of an electrically highly conductive material.
  • the contact bodies 16 are all of the same design. They are delimited by flat surfaces on the two end faces facing the walls 12 of the recess 11 and have an axial length measured from one end to the other, which is less than the axial length of the recess only by the play required for mobility in the recess 11.
  • each of the contact bodies 16 forms a mouth 17.
  • One flank 18 has the shape of a wedge with a rounded cutting edge.
  • this flank 18 forms two or three teeth 19 of the same design, which extend from the base 20 of the mouth 17 with at least approximately the same height to the free end of the flank 18.
  • the cutting edges of these teeth 19 define a plane which includes an angle of more than 90 ° with the base of the mouth 20.
  • the other flank 21 of the mouth 17 is formed by one leg of an angled arm, designated as a whole by 22, the other leg of which partially forms the base of the mouth 20.
  • the angle that these two legs enclose is slightly less than 90 °.
  • the free end portion of the flank 21 tapers like a wedge, the cutting edge of the wedge being rounded.
  • the flank 21, like the flank 18, has two to three teeth 23 which, like the teeth 19, are spaced apart in the longitudinal direction of the channel 7 and extend over part of the length of the flank 21 up to its free end. As FIG. 2 shows in particular, the height of the teeth 23 initially increases towards the free end and then decreases again in the wedge-shaped end section.
  • the side surface of the mouth 17 defined by the cutting of the teeth 23 does not lie parallel to the other side surface in the exemplary embodiment, but rather approaches it slightly towards the free end of the mouth.
  • flank 21 permits elastic deformation, in the sense of an expansion of the mouth 17.
  • the elastic expansion of the mouth 17 is supported not only by the greater length of the flank 21 compared to the flank 18, but also by the exception of the end section constant thickness of the flank 21 and the section of the arm 22 which adjoins it and partially forms the base 20 of the mouth 17.
  • the mouth width is smaller than the dimension of the core 2 'of one of the conductors 2, measured at the transition from the two flat inner sides to the cylindrically curved outer side, and so much smaller that the widening of the mouth by one elastic deformation of the arm 22 is so great that the teeth 19 and 23 press against the core 2 'with the desired contact pressure when the conductor 2 is inserted into the mouth 7 and the teeth 19 and 23 have not only cut through the insulation 3, but also penetrated into the core 2 'in the two opposite areas, which are present from the rounded corner zones at the transition from the two inner sides to the cylindrically curved outer side, as shown in FIG.
  • This figure further shows that the height of the teeth 19 and 23 is chosen so large that after penetration of the insulation 3 they still penetrate into the soul 2 'to the extent desired and the size of the contact surface.
  • segment conductors can be contacted with the help of the contact bodies 16, but also round conductors, provided that their diameter lies in the area in which the dimension of the contactable segment conductors, measured between the two outer corner zones, lies. The size of this area depends on the elastic expandability of the mouth 17.
  • the flank 18 and the arm 22 adjoin the central section of the contact body 16, which, like the flank 18, is delimited on the side facing away from the mouth 17 by a cylindrically curved surface 24, the curvature of which bears on the curvature of the contact surface 13 of the depression 11 is adjusted.
  • the contact Body 16 is therefore rotatable about an axis parallel to the longitudinal axis of the channel 7 in the recess 11 relative to the clamp body part 5. So that the contact body 16 does not emerge from the depression 11 during this rotation, the angle which the outside of the material section 18 forms with that of the flank 21 is less than 90 °.
  • the middle section of the contact body 16 is provided with a through bore 25 lying parallel to the mouth 17, into which a threaded bore, which runs perpendicularly thereto, opens, in which a clamping screw 26 is guided.
  • the end of the clamping screw 26 facing away from the through bore 25 points against the opening 15. Therefore, the clamping screw 26 can be actuated from the outside, so that it is also possible to connect the branch conductor 1 only when the terminal body is already closed, or the branch conductor 1 to detach from the contact body 16.
  • the free end of the flank 18 lies on the insulation 3 in the region of one outer corner zone, while the flank 21 on the insulation 3 is at a distance from the other outer corner zone. If the two clamp body parts 5 are now moved towards one another by tightening the clamping screws 9, the teeth 19 of the flank 18 begin to cut into the insulation 3. As a result, the free end of the flank 21 approaches the other corner zone, but does not cut into the insulation 3 there until this corner zone has almost been reached. During the further movement of the two clamp body parts 5 against one another, the contact bodies 16 execute a rotary movement in the depressions 11. As a result, the free end of the flank 21 approaches the longitudinal center line of the cable.
  • the clamp body parts 5 are removed again. In this case, however, slots must be provided in the terminal body parts 5 for the branch conductors 1, unless a connection is only possible after the contact bodies have been attached.
  • the contact bodies 16 can then be covered by means of a sleeve, which is poured out, for example, with casting resin.
  • the outer jaw flanks 521 are formed by the contact bodies 516.
  • the inner jaw flanks 518 consist of electrically insulating material and are formed by the two clamp body parts 505.
  • the latter each have a centrally arranged partition walls 505 "which projects into the cable receiving channel and which is perpendicular to the separating surface and which, in the assembled state, engage between the adjacent cores.
  • To the base of these partition walls 505" are molded the tooth-shaped elements 519 which penetrate the core insulation Form elements of the inner mouth flank.
  • the contact bodies 516 are rotatably mounted in the terminal body about an axis running parallel to the longitudinal axis of the cable receiving channel.
  • the contact bodies 516 are offset from one another in the longitudinal direction of the cable receiving channel, as a result of which long creepage distances are also achieved with this terminal.
  • the insulation of the wires is not under a pressure load which would lead to the wire insulation flowing.
  • FIG. 5 shows a first exemplary embodiment of the sleeve according to the invention with the clamp according to the invention.
  • the clamp designated as a whole as 31
  • the wires 32 of the main cable 33 need only be exposed in one piece, as is clearly shown in FIG. 5, which is not significantly longer than the clamp 31 in the axial direction.

  • the sleeve housing designated as a whole by 38 and made of the same plastic as the clamp body parts 34 and 35, is divided in the longitudinal direction like the clamp body, the division plane coinciding with the division plane of the clamp body. Screws 39 hold the upper part 38 'of the sleeve housing together with the lower part 38 "on both long sides. However, the two parts 38' and 38" of the sleeve housing are also held together by the clamp body parts 34 and 35, since the upper part on the clamp body part 34 along which an edge extending in the circumferential direction is formed on the latter. Correspondingly, the lower part 38 ′′ is molded onto the clamp body part 35.
  • the sleeve housing 38 tapers conically up to the insertion opening for the cable 33 that is aligned with the clamp channel of the clamp 31, the inside diameter of which is somewhat larger than the outside diameter of the Cable 33, since an annular seal 40 is to be provided in the area of the insertion opening, which seals the insertion opening together with the cable 33.
  • the lower part 38 '' of the sleeve housing 38 is in Area between the terminal 31 and an inwardly open annular groove drawn toward the main cable 33.

  • the upper part 38 'of the sleeve housing 38 has that above the main cable Area a much greater distance from the main cable than the lower part 38 ′′, because here a filler opening 44 for the casting resin is provided on the sleeve housing, with which the sleeve housing is poured out after assembly, and a ventilation opening 45.
  • the two parts 38 'and 38 "of the clamp body 38 must be provided with windows which allow access to the screws of the clamp because of their shaping to the clamp body parts 34 and 35, however, these windows can be closed without difficulty before the casting resin is introduced Due to the shaping of the clamp body parts, the socket housing 38 is inevitably correctly positioned, which considerably simplifies the assembly and allows the dimensions of the socket housing to be kept to a minimum without endangering reliable protection of the clamp and in particular of the contact surfaces produced with it.
  • the sleeve housing designated as a whole by 138 has a shape which largely corresponds to the shape of the sleeve housing 38 of the embodiment according to FIG.
  • the sleeve housing 138 consists of two successive sections in the axial direction, of which only one is molded onto the two clamp body parts 134 and 135. It is, as shown in FIG. 6, the portion which extends from the clamp 131 with a conical taper towards the end which only forms an insertion opening for the main cable 133.
