Definitions

  • the invention relates to a clamping device for producing a branch on the main conductor of a live voltage cable with a main terminal that can be placed on the uncut main conductor and also with a spaced branch terminal for receiving the end of a branch conductor in a clamping channel that contains a pressure screw for contacting.
  • It has a milling screw for penetrating the insulation of the main conductor to be contacted and for the longitudinal closure of its receiving channel leading the portion of the main conductor to be contacted has a molded body which can be pushed onto a base body, the individual electrical contact parts each in a pressure-resistant and dimensionally stable, electrically insulating Plastic existing insulating body are included and connect the main body of the main terminal with the main body of the branch terminal via a connecting web, wherein a connecting rail is guided in the connecting web, which connects or contacts the contact parts of the main terminal and the branch terminal with each other, and wherein the main body of the main terminal undercuts and has lugs, via which, with the formation of a downward and / or laterally opening insertion opening, the one adapted to the lugs and undercuts and rounded off there Molded body can be pushed on.
  • This single-phase clamping device allows the production of a branch on voltage cables, with or without potential disconnection on the separate main conductors the main cable can be connected to a particular main conductor by means of this clamping device. It is possible to make the subsequent sealing of the branch point and the mechanical protection against external forces quickly and easily, using shrink fittings.
  • the main clamp of the clamping device described above has a base body which has an extension downward in the form of an approximately C-shaped shape, within which the main conductor to be contacted by the main clamp and the lateral insertion opening on the side legs of the C-shape are guided Has approaches and undercuts, by means of which an adapted molded body can be slid on with the longitudinal closure of the receiving channel.
  • the lugs on the side legs of the C-shape and the lugs on the undercuts of the molded body to be slipped there bend.
  • Manufacturing the clamp body from dimensionally stable and pressure-resistant plastic material therefore encounters considerable difficulties when using conventional, electrically insulating plastic injection molding materials.
  • the 2-way angled contact part is also loose and unprotected inside the insulating housing or the receiving channel of the terminal.
  • a branching device for cables is also known.
  • the main terminal and the branch terminal of this weighing device are connected to one another via an electrically conductive bend, the main cable and the branching cable being clamped in each case with the aid of a clamping screw.
  • the task for the present invention is to design a branch clamp for cable branch shrink fittings in such a way that a symmetrical distribution of force within the closure body of the main terminal after contacting the main conductor also occurs with the external forces acting on this branch after the branch has been produced, in particular the Plastic parts of the clamp should be dimensionally stable in this area, and there is a reliable contacting of the conductors over a long period of time.
  • the angled component formed from the two contact parts of the main and the branch terminal and the connecting rail is embedded on all sides within the plastic material of the wall of the main body of the main and branch terminal and the connecting web, or is extrusion-coated therewith, and thus above the Receiving channel of the main conductor is fixed, this component maintains its predetermined position even with larger external pressure and tensile loads on the branch. Movements relative to the contacted main conductor are therefore no longer possible.
  • the branch terminal can run parallel to this over a large part of the length of the main body of the main terminal.
  • a symmetrical design and arrangement of the molded body of the terminal to be slipped on the underside of the main body of the main terminal and fixing the main conductor there is possible.
  • the shaped body can be fixed laterally, in particular also in the upper region, almost over the entire length of the main body of the main terminal up to the branch of the connecting web of the main terminal. With forces acting on the main conductor in the receiving channel, a uniform application of force on the left and right side of the main terminal is thus possible.
  • the main body of the main terminal is designed as an elongated insulating body which is curved in a bowl-shaped manner from above and laterally outwards and covers the outside of the main conductor, which is rounded in cross section, preferably only a relatively narrow one Shaped body is used and for this only in the front area of the main body of the main terminal parallel guides are placed on the side of the milling screw.
  • the insulating body In the longitudinal direction of the insulating body, symmetrically on the right and left outside, these have, as holding ribs, the undercuts and projections provided for locking and guiding the molded body of the main terminal.
  • the molded body can be pushed onto the holding ribs in a snug or press fit, preferably a U / V-shaped bracket which laterally engages in the upper side of the base body is used as the molded body.
  • the upper ends of the sides of the frame which are mirror-symmetrical to the central axis of this frame, are designed as bends with undercuts and shoulders, which each engage in the corresponding undercuts or shoulders, which are located on the outside of the base body or the holding ribs there.
  • a spring element is preferably inserted in the leg angle of the U-shaped or V-shaped bow-shaped molded body, which resiliently presses the main conductor introduced there against the milling screw.
  • the spring element consists of a leaf spring which is resiliently mounted via a recess and acts against the convex underside of a notched plate which is curved in the manner of a cylinder wall section and which has notched teeth or transverse ribs on its concave inside, which preferably have a free web height which is greater than the insulation thickness of the insulation of the executive to be contacted.
  • the shrink sleeve While in the previously described older clamping device the connecting web is placed approximately in the middle of the length of the housing of the main terminal, the shrink sleeve having to be guided over this area over the two ends of the main clamp, in the new clamping device according to the invention the shrink sleeve only has to be up to the connecting web applied at the terminal end can be guided, where it is possible to seal the shrink sleeve against the insulating body of the main terminal, which rests in a shell-like manner on the main conductor and extends with its curved outer surface onto the main conductor.
  • a seal length of z. B. 2 cm To seal the main terminal on the side running out in front of the connecting web.
  • This shaped element is wrapped from the outside with the end portion of the shrink sleeve that runs out there, so that the shaped element comes into direct contact with the hot-melt adhesive on the inside of the shrink sleeve during the shrinking process and the sealing of the main conductor is brought about by this molding during the shrinking process.
  • the form or sealing element is squeezed together by the shrink sleeve and lies tightly on the top of the main conductor or on the inside of the shrink sleeve.
  • the main body of the main clamp is also convex on this front side opposite the branching of the connecting web, the retaining rib formed there by the right and left side Protrusions and undercuts are closed by the pushed-on U-shaped molded body. In this way, an optimal seal to the main conductor can be achieved at this end of the main clamp by the shrink sleeve to be sealed there in the shrinking process.
  • the branch clamp of the branch conductor is preferably sealed in a conventional manner via a piece of shrink tubing which is pulled over the end of the branch conductor or the as yet uncontacted branch clamp and then positioned after connection of the branch conductor and shrunk onto the branch clamp and the branch conductor.
  • the sealing of the main body against the main terminal the main conductor can of course also be done in a conventional manner by means of a shrink sleeve such that it is wrapped around the main body of the main clamp and the pushed-on U-shaped molded body over the entire length of the clamping device.
  • the shrink sleeve must have a recess, so that the shrink sleeve with this recess can first be put over the lateral branch clamp and the connecting web between the main and branch clamp.

  • the insulating body (13, 14) and the outer insulating material of the connecting web (12) are made as a one-piece plastic part in the injection molding process, an extremely pressure-resistant and dimensionally stable material being used.
  • the connecting rail (12) and the electrical contact part (10) of the main terminal are encapsulated on all sides by the plastic material, so that apart from the bore area of the contact screw (3) of the main terminal, these two parts are not recognizable or touchable from the outside.
  • the main clamp (2) consists of the elongated, laterally rounded base body (5) shown in plan view in FIG. .
  • a receiving space (22) is formed between the underside of the base body and the inside of the pushed-on molded body, in which the uncut main conductor for producing the branch is to be inserted.
  • the molded body (6) is pulled off the front section of the main body (5), put over the main conductor not cut and then pushed over the main body which is placed on the main conductor and bulges over the main conductor and is fixed there.
  • the locking of the molded body takes place in principle simultaneously with the contacting of the main conductor, which is fixed in the insertion opening of the clamp by the milling screw (3) in the leg angle (31) of the bow-shaped molded body (6). (see Fig. 9)
  • This counter bearing to the milling screw (3) is formed according to FIG. 12 by a notch plate (33) and a leaf spring (35) resting against it. These two parts are mounted in a recess (32) which is opened inwards in the plastic material of the molded body (6).
  • the U-shaped shaped body has mirror-symmetrical bow sides with bends at their upper ends correspondingly mirror-symmetrical to one another, which form undercuts (27, 28) and shoulders (29, 30).
  • undercuts and shoulders are formed over the entire width of the shaped body (6) cooperate with undercuts (18, 19) and shoulders (20, 21) placed laterally above the main body (5) of the main clamp. These approaches and undercuts also run in the longitudinal direction of the base body, with all undercuts and approaches being press fit or snug fit.
  • the shoulders (20, 21) of the base body (5) form elongated retaining ribs which engage from below behind the inwardly bent shoulders (29, 30) of the upper temple ends.
  • the outside of the molded body (6) and the top of the base body (5) of the main clamp are matched to one another in such a way that the outer sides continuously merge.
  • the entire upper side of the clamp body thus forms a continuously curved surface, the lateral recesses of which are closed by the pushed-on molded body.
  • This adapted shape of the molded body and base body is also provided laterally and in the front end region of the clamp, where all the edges and corners projecting outwards are rounded off.
  • the outer surface of the main terminal can thus be sealed against the cable jacket of the contacted main conductor without difficulty by means of a shrink sleeve.
  • this seal and for guiding the main conductor into the receiving channel (4) of the main terminal is the creation of a wall extension (25) of the shell-shaped, outwardly bent insulating body (13) of the main terminal, this wall extension extending down into the area of the main terminal the main conductor to be inserted is pulled and extends in the longitudinal direction of the main terminal over the rear region of the insulating body (13) and thereby directly continues the inside of the pushed-on molded body.
