Definitions

  • the invention relates to a device for releasing and withdrawing a multi-conductor cable cast into a block and provided at the ends with contact terminals from a connector housing.
  • Printed circuit units such as those used in electrical circuits, in particular for data processing systems, contain circuit boards, known as boards, each equipped with a plurality of circuit cards, and such a plate unit usually consists of a printed circuit board, a reinforcing layer thereon, one attached to this card guide and the circuit cards which are mounted in the card guide for making the necessary electrical contacts with the plate.
  • the associated contact pins and rails for the signal lines and zero voltage conductors are located on the opposite side of the plate.
  • three-conductor cables consisting of a signal conductor and two zero are often used -Leads that are encapsulated together in dielectric material to ensure the required impedance.
  • the connections of these three conductor cables are designed as contact terminals, namely one terminal each for the signal voltages and for the neutral conductors.
  • the individual conductors are connected to the terminals, and this arrangement is detachably guided in a common connector plastic housing, which makes it easier to put on the contact pins and rails of the circuit board.
  • the invention has for its object to provide a tool with which the ladder, for. B. a three-wire arrangement, can be released from the connector housing without the risk of damaging the conductor.
  • the device according to the invention makes it easier to detach and pull out the multi-conductor cable from the connector housing, in particular by pulling it out more quickly and thereby preventing damage to the individual conductors.
  • the connector housing is first detached from the circuit board and then the spring tongue provided according to the invention is inserted between the connector housing and the encapsulation of the conductors until the hook located there engages behind the front edge of the cable block.
  • the grooved attachment of the tool slides on the guide part of the connector housing and ensures that the tool is aligned with the cable.
  • the handle By actuating the handle against the force of the spring, the cable is then simply pulled out.
  • a three-wire cable 10 is inserted into a connector plastic housing 11.
  • the three-wire cable 10 consists of a central signal voltage conductor 12 and two outer neutral conductors 13.
  • the signal voltage conductor 12 crosses one of the neutral conductors 13 and is connected to a fork-shaped contact terminal 14, preferably by so-called crimping, while the two neutral conductors 13 are connected in the same way to a contact terminal 15.
  • the contact terminals 14 and 15 lie in one plane.
  • the areas in which the signal voltage conductor 12 crosses one of the neutral conductors 13, and in which the connection of the conductors to the contact terminals 14 is located, are located in a cable block 16 made of dielectric material, which is preferably designed as a dielectric film.
  • the ends of the contact terminals 14 and 15 are provided with barb-shaped lugs which engage behind locking latches 18 on the connector housing 11, as a result of which the contact terminals 14, 15 and thus the three-wire cable 10 with the cable block 16 are detachably fastened in the housing 11.
  • the opening between the cable parts of the contact terminal 14 is aligned with an opening 19 in the housing 11, which enables it to be plugged onto a corresponding pin on the printed circuit board.
  • the housing 11 furthermore has a slot 20 which is aligned with the opening between the two cable parts of the contact terminal 15 and enables the plugging onto the zero conductor rail of the printed circuit board.
  • a guide part 21 of T-shaped cross-section on the housing 11 serves to align and guide the tool described below for loosening and pulling out the three-wire cable.
  • the tool shown in FIGS. 3 and 4 consists of a cylindrical housing shell, in which a piston 23 is guided in a longitudinally displaceable manner.
  • a handle bar 24 In a radial bore 26 of the piston 23 there is a handle bar 24 which is guided through slots 25 in the housing jacket 22 and thus enables a limited longitudinal movement of the piston 23 in the housing jacket 22.
  • a compression spring 27 is arranged between a pressure piece 28 on the rear of the piston 23 and a shaft 29 of a button 30.
  • the button 30 is attached to the housing jacket 22 by means of a pin 31.
  • the tool To release and pull out the three-wire cable 10 from the connector plastic housing 11, the tool is inserted into the housing in the position of the piston according to FIG. 4, that is to say with the compression spring 27 relaxed, such that the spring tongue 32 between the housing 11 and the cable block 16 passes so far forward that the hook 33 engages behind the front edge of the cable block 16.
  • the interaction of the guide part 21 with the grooved shoulder 35 serves to secure the relative position between the tool and the housing 11 (FIG. 2).
  • a three-wire cable is located in the connector housing 11. If, contrary to this example, the housing 11 accommodates a plurality of multi-conductor cables, one multi-conductor cable after the other is pulled out in the manner described with the tool described
