Definitions

  • the invention relates to a device for connecting cable wires to insulation displacement contacts of Dropwire connection strips of telecommunications technology according to the preamble of claim 1.
  • a press-in tool of the generic type is previously known from DE 35 22 131. This consists of a shaft with a grip part as an actuating surface at one end and with guide and insertion webs at the other end for pressing the cable wires into the insulation displacement connection contacts of the Dropwire connection strip.
  • Dropwire connector strips are previously known from DE-GM 81 21 721.
  • the spacing of the clamping ribs is designed for the thick insulating sleeves of the Dropwire cables. This means that the clamping ribs cannot reliably grasp thin cable cores that are pressed into the insulation displacement contacts of the Dropwire terminal block using the insertion tool. It has consequently been found that the thin cable cores can come loose from the insulation displacement contacts of the Dropwire connection strips when vibrations acting on the Dropwire connection strips, since the relatively thin insulating sleeve of the thin cable cores is not reliably gripped by the clamping ribs of the Dropwire connection strip .
  • the invention solves this problem with the device defined in claim 1, with which cable wires can be connected to the Dropwire insulation displacement contacts arranged in the Dropwire connection strips in one work step and can be securely fixed in the Dropwire connection strip.
  • the insertion tool is designed as a locking plug for holding cable wires in the Dropwire connection strips.
  • a plastic locking plug By using a plastic locking plug, on the one hand, cable wires can be pressed into the insulation displacement contacts of Dropwire connection strips and, on the other hand, can be securely held in the Dropwire connection strips, since the insertion tool as Locking plug remains in the Dropwire connector strip.
  • Retaining ribs are formed on the underside of the insertion webs of the insertion tool as a receptacle for the cable wires.
  • the press-in webs of the press-in tool are formed from two latchable half-shells connected by a film hinge, on the inner sides of which a groove-like insertion channel forming the receptacle for the thin cable wire is formed.
  • the cable core is inserted into the unfolded half shells and fixed between them when the half shells are folded together. After the insertion tool designed in this way has been pressed into the Dropwire connection strip, the cable core is securely fixed.
  • a particularly important advantage of the push-in tool according to the invention, which forms a locking plug, is that the cable core is centered by the push-in tool when it is introduced into the Dropwire terminal strip, so that a secure contact connection between the cable core and the insulation displacement contact of the Dropwire terminal strip is ensured. It is also particularly advantageous that the cable core can also be pulled out when the lock plug is pulled out.
  • the insertion tool consists in particular of an impact-resistant plastic which can be produced inexpensively by injection molding.
  • the cable cores 29 are so-called cable cores which are to be connected to Dropwire connection strips 2.
  • the Dropwire terminal block 2 shown in Fig. 1 comprises ten slot chambers 18 arranged in a row, in which insulation displacement contacts, not shown, are arranged.
  • Each slot chamber 18 is provided on the front of the Dropwire connection strip 2 with a V-shaped clamping slot 17, the sides of which are formed by clamping ribs 19 provided with inclined clamping surfaces.
  • insulation displacement contacts to which cable wires 29 are to be connected, are arranged in a manner not shown, known from DE 34 15 369.
  • the distance between the clamping rib 19 of a clamping slot 17 of the Dropwire terminal block 2 is designed to hold Dropwire cables which are provided with a relatively thick insulating sleeve around the cable core.
  • the insertion tool 3 is designed as a locking plug 20, 21 made of plastic.
  • the underside of such a locking plug 20 in the first embodiment of the insertion tool is shown in more detail in FIG. 2.
  • the locking plug 20 comprises the guide web 9 for engaging in the T-shaped slot chamber 18 de Dropwire connector strip 2 and two insertion webs 10, between which the slot 12 for receiving the insulation displacement contact, not shown, when pressing the locking plug 20 into the slot chamber 18 de Terminal block 2 is recessed.
  • the locking plug 20 is provided on the underside of its insertion webs 10 with a receptacle for a cable wire 29, the receptacle being formed from retaining ribs 28 between which the cable wire 29 is pressed in when wiring, so that the cable wire 29 when the locking plug 20 is pressed into the Slit chamber 18 of the Dropwire connector strip 2 is centered.
  • the locking plug 20 can be used for wiring are pressed by hand with a cable wire 29 into the slot chamber 18 of the Dropwire connector strip 2 and remains in the chamber 18th
  • the two push-in webs 30, which include the slot 12 for the insulation displacement contact, are formed from two half-shells 32 connected by a film hinge 31, one of which a half-shell 32 is firmly connected to the guide web 9.
  • a groove-like insertion channel 33, which forms the receptacle for the thin cable core 29, is formed on the inner sides of the half-shells 32.
