Definitions

  • the invention relates to a connection tool for connecting incoming and outgoing conductors to contact elements in connection modules according to the preamble of claim 1.
  • connection tool which has an ergonomically shaped handle with a double-T-shaped tool head with a slot in the central web.
  • a conductor is pressed into the contact slot of an insulation displacement contact element, the insulation displacement contact element engaging in the slot, so that the tool head can engage the conductor on both sides of the sheet-shaped insulation displacement contact element and press it into the contact slot .
  • the insulation of the conductor is cut in by means of the sharp-edged cutting edges of the contact legs and the metallic conductor is electrically contacted with the insulation displacement contact element.
  • This known tool is suitable for the connection of smaller wire diameters to insulation displacement contact elements and cannot always be sufficiently brought into a convenient handling position.
  • EP 0 040 307 B1 describes a tool for the electrical connection of insulated conductor wires, in which a striking mechanism and a plunger which can be displaced longitudinally against spring force are arranged.
  • the plunger head protrudes from the front of the handle and is used to push the end of the conductor into the contact slot.
  • the plunger head also has a wire cutter for cutting off the conductor wire after being pressed in.
  • the object of the invention is to develop a multifunctional connection tool with which a convenient and reliable connection and disconnection of cable cores for a wide range of wire diameters in connection modules are guaranteed.
  • the invention provides that a combined cutting and pressing device, consisting of a pressure screw with springs, a knife holder with knives, a cam housing, is introduced through a front opening of the housing handle, and that a cover is provided, which slides on the housing handle when the cutting and pressing device is actuated.
  • the cover with the cutting and pressing device can be locked in four latching positions on the housing handle, so that the connection tool is easy to handle for every connection situation.
  • the cam control makes it easy to cut cables with a large conductor diameter with little effort and then press them into the contact slot of the connection module. The one you need The force is not greater than for pushing the cable into the contact slot.
  • connection tool is simple and robust and easy to assemble.
  • the connecting tool consists essentially of a one-piece Housing handle 1, a cover 2, a tool head 23, consisting of a knife carrier 3, a cam housing 4, two knives 5, a pressure rod 6, springs 7, 8, 9, locking rings 10, 11, and one from the housing handle 1 swiveling out wire diameter measuring and release device 12, a pin 13 and a split pin 14th
  • connection tool is suitable for connecting copper cables with a cross section of up to 2.5 mm 2 or with conductor diameters of 1.8 mm or cable diameters of 3.8 mm in connection modules up to 1000 V.
  • connection and cable disconnection process takes place in the reverse order to the process with the known connection tools for the insulation displacement connection technology (application tool according to EP 0 040 307 B1).
  • connection tool is brought to this cable position and pressed down.
  • the cable is first cut to length and only then pushed completely into the contact slot. The cut cable end is covered after being pressed in and is no longer accessible.
  • the tool is designed to be handy and requires no more effort to cut strong cables than to press it in alone.
  • the reduction in effort is due to the applied Cam control achieved by means of the cam housing 4 (Fig. 11, 12).
  • the entire cutting / pressing device of the tool, the tool head 23, consisting essentially of the cam housing 4, the spring 9, the knife holder 3 with the knives 5, in the through bore of which the pressure rod 6 is guided with the spring 7, and the Circlip 11, made of pin 13 and spring 8, is inserted from the front through a circular opening 17 in housing handle 1 (FIGS. 3, 4) and is inside at position 19 (FIG. 3) through split pin 14 (FIG. 1,2,4) secured on the handle 1.
  • the cover 2 is snapped into the housing handle 1 via latching elements 15 of the cover 2 in grooves 20 of the housing handle 1 (FIGS. 1a, 4).
  • the cover 2 (Fig. 5,6) has four axial ribs 18, which allow rotation of the tool head 23 in each case by 90 ° with respect to the housing handle 1 in four latching positions, so that the cutting / pushing device comes into contact with the contact to be connected can be done as it is most convenient for reliable tool handling.
  • the cover 2 slides axially along the housing handle 1 as far as the tool is actuated (FIG. 2).
  • connection tool operates as follows in accordance with the illustration in FIG. 2:
  • the knives 5 with the knife edge 30 and the knife shaft 28 are on the knife holder 3 (Fig. 7,8) mounted around the pivot point 21 of the pin 13 with the spring 9 (Fig. 1,9) and slide over the cam housing 4 when the tool is pressed onto the wire to be switched on to cut it to length .
  • the knife carrier 3 slides along the inside 22 of the cam housing 4 (FIG. 11) until the wire is cut off.
  • the cam housing 4 is pushed over the knife carrier 3.
  • the cam housing 4 consists of a cylindrical hollow body 33 with a groove 35 and with guide or spreading surfaces 29 for guiding the knife shanks 28.
  • a flattened bore 34 on the inside provided for holding the compression spring 8 (Fig. 12).
  • the preassembled knife carrier 3 is inserted into the cam housing 4 and is fixed on the cam housing 4 by means of a locking ring 10.
  • the pressure rod 6 slides further inside the knife carrier 3 back to the point at which it comes to rest against the rear wall 32 of the housing handle 1 (FIG. 1, 2) and presses the wire to the bottom into the contact slot of the connection module.
  • the entire mechanism is retracted into the starting position by the force of the springs 7, 8, 9 (FIG. 1).
  • the compression spring 7 is pushed onto the compression rod 6 and fixed by means of the locking ring 11.
  • the tool When depressed, the tool is supported with the head piece 27 of the pressure rod 6 (FIG. 13) on the connection module, the knife shafts 28 (FIG. 10) slide along the oblique, wedge-shaped guide or spreading surfaces 29 of the cam housing 4 so that the knife edges 30 (Fig. 10) close like scissors and cut the wire on the side of the contact slot of the connection module.
  • the spring 9 ensures that the cutting edges 30 of the knives 5 are returned to the starting position after a wiring process.
  • the shearing movement of the knife edges 30 takes place around the pivot point 21 formed by the pin 13.
  • the locking ring 10 limits the spring 8, which loads the knife carrier 3 in the interior of the cam housing 4, in its extent.
  • the circlip 11 limits the spring 7, which loads the pressure rod 6 inside the knife carrier 3, in its extent.
  • the rotatable from the housing handle 1 via an axis 26 and device 12 which can be folded out downward (FIG. 1, 14) has measuring openings 24, through which the wire diameter and also the insulation diameter can be read.
  • a hook 16 is provided in the unfolded tip 25 for releasing the cables pressed into the connection element of the connection module.
