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, which leads to penetration of the insulation of the main conductor to be contacted and a milling screw and to the longitudinal closure of its leading portion of the main conductor to be contacted
Receiving channel has a molded body which can be pushed onto a green body, and furthermore with a spaced branch clamp for receiving the end of a branch conductor in a clamping duct, which contains a pressure screw for contacting, wherein the individual electrical contact parts are each accommodated in an insulating body made of pressure-resistant and dimensionally stable, electrically insulating plastic and connect the base body of the main terminal to the base body of the branch terminal via a connecting web, a connecting rail which guides the contact parts of the main terminal being guided in the connecting web and connects or contacts the branch terminal, and wherein the main body of the main clamp has undercuts and lugs, by means of which the molded
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 above-described clamping device 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 bend and also the lugs on the undercuts of the molded body to be slipped on there.
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.
the task for the present invention is to form a branch clamp for cable branch shrink fittings according to patent application P 37 10 546 in such a way that a symmetrical force distribution within the closure body of the main terminal after contacting the main conductor also in those acting on this branch after the branch has been produced External forces occur, in particular the plastic parts of the terminal should be dimensionally stable in this area, and a reliable contacting of the conductors is given over a long time.
the object is now achieved with the aid of a clamping device of the type described in the introduction according to the features of patent claim 1.
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.
the insulating body of the branch clamp comes to lie at the lateral spacing of the main clamping body, which has a larger diameter. External loads act uniformly on both the main terminal and the branch terminal over the entire length of the clamping device.
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, from the top laterally outwardly curved bowl-shaped, the outside of the rounded cross-section of the main conductor from above, preferably only a relatively narrow Shaped body is used and for this only in the front area of the main body of the main clamp 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 frame sides which are formed mirror-symmetrically to the central axis of this frame, are designed as bends with undercuts and lugs, which each engage in the corresponding undercuts or lugs, which are located on the outside of the base body or the holding ribs there.
a cushioning of the contact part in the area of the milling screw relative to the terminal body is not possible.
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.
Another advantage of the design of the clamping device according to the invention in which the connecting web between the main body of the main terminal and the branch terminal is only applied to the outer upper end of the insulating body of the main terminal, is further that the shrink sleeve required to seal the main terminal and the main conductor guided there can be of simple rectangular dimensions.
this shrink sleeve does not require a "recess" through which the connecting web there is to be guided in the above-described clamping device.
the connecting web is placed approximately in the middle of the length of the housing of the main clamp, 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 molded element is wrapped from the outside with the end portion of the shrink sleeve that runs out there, so that the molded 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 not yet contacted branch clamp and then positioned after connection of the branch conductor and shrunk onto the branch terminal 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 base 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.
FIG. 1 of the clamping device (1) shown in the drawings it consists of a main clamp (2), a branch clamp (7) being placed on the right next to it.
the main terminal (2) and branch terminal (7) are connected at the upper end of the main terminal by a connecting bar (16).
a connecting rail (12) is introduced within this connecting web (16), which connects the electrical contact parts of these terminals running in the longitudinal direction of the main terminal and the branch terminal.
a clamping channel sleeve is formed within the contact part of the branch terminal, the contact part with the section running out in the sleeve being surrounded from the outside with electrically insulating, pressure-resistant plastic material.
a bore is made through this outer jacket and the clamping channel sleeve, in which a pressure screw (9) for contacting the end of the branch conductor to be fixed there can be screwed.
the main body (17) of this Abzwei terminal has an insulating body (14) on the outside, which laterally merges into the connecting web (16) bent there to the left, which in turn opens into the outer insulating body (13) of the main terminal.
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 cannot be seen or touched from the outside.
the main clamp (2) consists of the elongated, laterally rounded base body (5) shown in plan view in FIG. 1 and a molded body (6) that can be slid on in the front region of the base body. .
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 shaped body is locked 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 shaped 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 molded body has mirror-symmetrical temple sides with bends at their upper ends correspondingly mirror-symmetrical to one another, which form undercuts (27, 28) and shoulders (29, 30).
undercuts and approaches are formed over the entire width of the shaped body (6) and cooperate with undercuts (18, 19) and shoulders (20, 21) placed laterally above the main body (5) of the main clamp. These shoulders and undercuts also run in the longitudinal direction of the base body, all undercuts and shoulders being press fit or snug fit onto one another.
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 curved insulating body (13) of the main terminal, this wall extension extending down into the area of the main terminal main conductor to be introduced is drawn and extends in the longitudinal direction of the main terminal over the rear region of the insulating body (13) and immediately continues the inside of the pushed-on molded body.
This wall extension (25) can be clearly seen in the cross-sectional representations of FIGS. 6 and 7 after the sections E-F and C-D of FIG.
the wall extension (25) has the same curvature on the outside as the outside of the insulating body (13) of the main terminal base body (5). On the inside, the curvature of this wall extension corresponds to the curved inner surface of the bow-shaped shaped body (6), which is clearly shown in detail in FIGS. 3, 5 and 9.
the connecting web (16) of the main terminal and the branch terminal is bent in a circular arc downward by the angle ( ⁇ ), so that the branch terminal (7) comes to lie laterally in the lower region next to the main terminal (2).
Branch clamp and main clamp thus form a U-shaped clamping device which, due to the bending of the connecting web, is guided with its upper outer side on an outer radial surface. Because of this shape, it is possible to arrange a larger number of clamping devices (2) next to one another in a circle and to contact different main conductors of a main cable in each case by means of a corresponding clamping device.
the clamping devices can be arranged next to each other in a compact manner, with external forces acting on the center of this circular arrangement of the clamping devices due to their external shape.
the length of the main body of the main terminal is 8.5 cm and the length of the main body of the branch terminal is 7 cm.
the outside diameter of the branch clamp which is circular in cross section, is about 2 cm and the maximum outside dimensions of the main body of the main clamp are 5 cm or 4 cm in cross section (height or width).
the height of the shaped body (6) is a maximum of 4.5 cm and the width the bow sides of the molded body 3.5 cm, the wall thickness being about 0.6 cm.
the elongated shape of the main clamp (base body (5) or molded body (6)), which is rounded at the ends, can be clearly seen, the base body of the main clamp being shown by the wall extension (25) on the side of the branch clamp is extended laterally in the area of this branch clamp.
the wall extension (25) acts on the one hand as a support body for the shrink sleeve to be shrunk on there, as well as protection against a voltage flashover between the main and branch conductors and as an additional holder for the contacted main conductor.
FIGS. 2 and 5 For clarification, the pressure screw (9) of the branch terminal and the milling screw (3) of the main terminal and the guidance of the electrical contact parts and the connecting rail (10, 11, 12) are shown in FIGS. 2 and 5. Furthermore, the shaped body (6) can be seen in FIG. 2 in the left area of the clamping device and — in FIG. 4, which represents the rear side of this clamping device — corresponding to the right of the illustration of this clamping device.
the structure of the molded body (6) which laterally and downwardly delimits the receiving channel (4) for the main conductor underneath the main body (5) of the main clamp and results from FIGS. 8, 9 and 10.
the continuous curvature of the outside of this U-shaped part can be clearly seen.
the insulating body (13) or the base body (5) of the main terminal is indicated above the molded body (6), the insulating body (13) increasing continuously by 6 mm up to the center of the main terminal.
the shaped body (6) has an adapted rounded shape.
FIG. 13 shows in detail the clamping device with contacted main conductor and branch conductor, the outer seal of the clamping device and the cables connected there being shown according to the method described in patent application P 37 10 546.8.
a shrink sleeve (37) is used to seal the main clamp (2), which has a recess in the region of the branching off of the connecting web (16). To assemble the shrink sleeve, this recess must first be placed over the branch clamp (7), after which the shrink sleeve (37) can then be wound around the main clamp and the main conductor and its cable coming in and out there and shrink-fit by heat.
a piece of shrink tubing (36) is used which, in contrast to a "shrink sleeve", is connected in the circumferential direction as a tube.
a hot melt adhesive On the inside of the shrink sleeve and the piece of shrink tubing there is a hot melt adhesive which, through the molding during the shrinking process, seals the conductors.
An additional outer shrink sleeve (38) is used to jointly seal several single-phase clamping devices.
the main terminal (2) and the branch terminal, as well as the indicated sections of the main conductor and the branch conductor corresponding to FIG. 1, are shown in a top view, the electrical contact parts running through the connecting web (16) being indicated in dashed lines are.
the inner shrink sleeve (37) and the outer shrink sleeve (38) as well as the shrink tube piece (36) sealing the branch clamp (7) are only indicated in cross section for differentiation.
the shrink sleeve (37) Due to the special shape of the clamping device and the connecting web (16) for the end of the branch terminal in the end area laterally above the main terminal, it is in principle possible to use the shrink sleeve (37) without creating a recess. Execution of the connecting web (16) branching off laterally from the main terminal only to lead to this branch.
the shrink sleeve (37) lies partially on the cable sheath of the main conductor or the wall extension (25) of the main terminal, which is partially guided laterally around the cable sheath, and the rest of the insulating body (13) of the main terminal and is inserted there by means of a plastic or elastic Molded body sealed to the outside.
the shrink sleeve (37) also has a hot melt adhesive, with which the molded element introduced seals the main conductor during the molding process during the shrinking process.
Such a glue-in plastic molding element (39) is shown in FIG. 14, this part being squeezed by the shrink sleeve (37) during the shrinking process and thus lying tightly against the conductor and the insulating body (13) of the main terminal.
the section of the insulating body between the end of the bow-shaped molded body (6) and the location of the branch of the connecting web (16) must have a length corresponding to the requirements for Seals, e.g. B. have a length of at least 2 cm.
the shrink sleeve (37) is wound in the area in front of the branch of the connecting web (16) around the main conductor guided below the main body of the main terminal or the shaped element (39) surrounding it from below and the upper insulating body (13) of the main body of the main terminal.
a plastic sealing adhesive such as a silicone sealing compound, is used in the gusset area between the main cable and the branch cable.
