Definitions

  • the present invention relates to a device of the type mentioned in the preamble of claim 1 and a method of the type mentioned in the preamble of claim 13.
  • DE-C-24 39 171 already shows a device of the type mentioned in the preamble of claim 1, in which the wires of the round cable are pressed onto a support plate by means of a hold-down device movable in the longitudinal direction of the cable or in the support plate trained grooves are pressed in and held.
  • the hold-down device In order to ensure that the wires are pressed into the receiving grooves assigned to them during this process, the hold-down device also carries out vibratory movements transverse to the direction of the wires. Characterized in that for the delivery of the hold-down, for its movement in the longitudinal direction of the cable and the vibration movement across the cable each own drives must be provided, this device is extremely complex and therefore expensive.
  • the known design principle leads to an unbearable design and manufacturing effort.
  • the hold-down device is designed as a flexible band, which is laid from one side across the more or less fanned out wire bundle of the round cable and therefore seizes the wires one by one and presses them side by side onto the support plate.
  • the pressing or lifting of the hold-down device can be represented by a simple rolling or rolling movement of the flexible band, which can be accomplished with simple technical means, as will be explained in more detail using an exemplary embodiment.
  • the support plate has a smooth contact surface and that the flexible band on its side facing the support plate has recesses for receiving one wire each is provided.
  • the recesses can be designed in such a way that when the flexible band is placed on them, they each capture exactly one wire, so that the wires with the spacings of the recesses correspond laterally to one another on the support plate and are held.
  • the flexible band is fixedly arranged with one end with respect to the support plate and the unwinding and reeling mechanism, which is adjustable transversely to the wires via the support plate, is assigned to the flexible band.
  • the flexible band on its side facing away from the support plate has a longitudinal guide profile which engages in a corresponding receiving profile of a guide rail which is oriented transversely to the wires and is adjustable parallel to the support plate, and that the guide rail has at least one to the support plate parallel and has at least one adjoining, diverging section to the receiving plate.
  • the part of the flexible band located in the parallel section is in the position placed on the support plate, while the part of the flexible band located in the diverging section is in a raised position, as shown in FIG of the execution example is explained in more detail.
  • the flexible band can be placed on or removed from the support plate by a simple linear movement of the guide rail.
  • the hold-down device is preferably formed by a link belt.
  • the division of the link band corresponds to the desired mutual spacing of the wires on the support plate.
  • the links each have a receiving profile corresponding to the outer contour of a wire on their side facing the support plate and a guide profile corresponding to the receiving profile of the guide rail on their other side.
  • the link belt is preferably made in one piece from plastic, the connection of the links to one another being established via so-called film hinges.
  • the guide rail can be adjusted in individual steps corresponding to the division of the limbs. This makes it easier for an operator to manually support the detection of the individual wires by the links.
  • two holding templates are provided with two mutually parallel support plates, the support surfaces of which face away from each other.
  • This arrangement makes it possible to form a row of wires in each of the holding templates.
  • a constructive solution is possible which allows these two wire rows to be formed simultaneously and in to maintain their predetermined mutual configuration.
  • each holding template is assigned cutting devices and devices for attaching a tab to the cut wire ends.
  • the cutting-to-length devices and the stop devices can be designed such that the two wire rows are each processed simultaneously.
  • a method matched to the device according to the invention is characterized by the features contained in claim 13.
  • the wire ends of the round cable are separated in successive process steps, aligned and held on a holding plate and cut to length while maintaining this clamping and attached to a flat connector.
  • a further embodiment of the method according to the invention also allows the wires of a round cable to be arranged in two parallel rows, held in this configuration and then cut to length and connected with a flat plug, as will be explained in detail using an exemplary embodiment.
  • the device shown in Fig. 1 essentially comprises a device housing 2, on which two support plates 4, 6 are arranged.
  • the support plates 4 and 6 are adjustably mounted on the device housing 2 in the direction of the double arrows 8 and 10. They can be moved towards or away from each other symmetrically to the center line 12 by an adjustment mechanism, not shown.
  • Toothed projections 14 and 16 are formed on the support plates 4 and 6, respectively, which engage in the corresponding recesses 18 and 20 provided on the opposite support plate when the two support plates 4 and 6 insert their into the Fig. 5 and 6, shown in the adjacent position.
  • the tooth projections 14, 16 and the associated recesses 18, 20 serve to fix the two support plates 4, 6 to one another in the correct position.
  • the outer sides of the support plates 4 and 6 facing away from the center line 12 each form support surfaces 22 and 24, on which the wires 26 and 28 of a round cable 30 can be placed.
  • the wires 26, 28 of the round cable 30 are roughly pre-sorted and brought over the contact surfaces 22 and 24, respectively.
  • the hold-down plates 4 and 6 are each assigned a hold-down device 32 and 34, which are described in more detail below with the aid of the hold-down device 32 .
  • the hold-down device 32 comprises a flexible band 36 designed as a link band; this is made, for example, in one piece from an elastic plastic.
  • the individual links 38 are connected to one another in a manner known per se via thinned material webs, so-called film hinges.
  • the individual members 38 have on their sides facing the support plate 4 recesses 40 for receiving one core 26 each. As can be seen in FIG. 1, these recesses 40 are shaped such that they form a wedge-shaped downward web 42 on one side, which each engages between two closely spaced wires 26 and separates them, so that each of the recesses 40 receives exactly one wire.
  • each of the links 38 is provided with a T-shaped guide profile 44 which fits into a corresponding receiving profile 46 a guide rail 48 aligned transversely to the wires 26 can engage.
  • the guide rail 48 is adjustable parallel to the bearing surface 22 in the direction of the double arrow 50.
  • the guide rail 48 On its side facing the support plate 4, the guide rail 48 has a section 52 which is parallel to the support surface 22 and an adjoining section 54 which diverges from the support surface 22.
  • the lower hold-down device 34 in FIG. 1 is formed symmetrically with respect to the center line 12 to the upper hold-down device 32 and comprises a flexible band 56 and a guide rail 58 which can be adjusted together with the upper guide rail 48 in the direction of the double arrow 60.
  • the flexible bands 36 and 56 are each fastened to the device housing 2 with their left ends in FIG. 1.
  • the two support plates 4 and 6 assume the most distant position shown in FIGS. 1 to 4.
  • the guide rails 48 and 58 have been inserted into the device housing 2 to such an extent that the respective inner link of the flexible bands 36 and 56 closest to the device housing 2 is located in the diverging section 54 of the associated guide rail 48 and 58; as a result, the flexible bands 36 and 56 are lifted off the associated support plates 4 and 6, respectively.
  • the wires 26 and 28 are more or less pre-sorted over the assigned contact surfaces 22 and 24. Then the guide rails 48 and 58, respectively 1 to the right, the links 38 of the flexible bands 36 and 56 sliding in succession along the diverging section 54 into the parallel section 52 and approaching the associated support plate 4 and 6, respectively. They each take one of the wires, press it against the associated support surface 22 or 24 and hold it there until all the wires are gripped.
  • the wires 26 and 28 are cut to length (FIG. 3).
  • a cutting device is arranged on the side of the device on which the free ends of the wires 26, 28 protrude beyond the associated support plates 4, 6, which is identified as a whole by 62. It consists of a counter knife 64 to be inserted between the two rows of wires 26 and 28, two rows common, and two cutting knives 66 and 68.
