Definitions

  • the invention relates to a contact device for a multiconductor cable, comprising a terminal support and a terminal cover to be placed on the upper surface of said terminal support, said terminal support and terminal.
  • cover being made of insulating material, said terminal support having recesses, each housing a terminal comprising a bifurcated insulation piercing contact, which extends from said terminal support upper surface towards said terminal cover, said terminal cover guiding insulated electrical conductors of said multicore cable across said bifurcated insulation piercing contacts.
  • Said contact device is known from the Dutch Patent Application 7603291.
  • the insulated electrical conductors are passed through separate bores in the terminal cover, after which the ends are bent along the lower surface of said terminal cover and pushed between the tines of the insulation piercing contacts, located in the terminal support.
  • the lower surface of the terminal cover comprises slots for accommodating the insulation piercing contacts, whereas transversely to each slot a deep groove is made for accommodating the bent end of the electrical conductor pressed between the tines of the insulation piercing contact.
  • said terminal cover comprises recesses for accommodating each a U-shaped portion of an insulated electrical conductor of said multicore cable, said recesses having their longitudinal direction in line with' the guiding direction of said conductor and extending from the terminal cover upper surface towards the terminal cover lower surface opposing said terminal support upper surface, said terminal cover also comprising slots accommodating said bifurcated insulation piercing contacts each slot extending from the terminal cover lower surface upwardly and opening into a recess for said U-shaped conductor portion, the width direction of said slot extending transversely to the longitudinal direction of said recesses, such that after placing said terminal cover on top of said terminal support each bifurcated insulation piercing contact in the assembled contact device extends within said recess transversely to said recess longitudinal direction, each U-shaped conductor portion being pushed in a respective recess such that the bottom portion of said U-shaped conductor portion being pushed into the slot between the tines of the bifurcated insulation
  • a supported, U-shaped bent conductor portion provides means for contacting the conductor with the insulation piercing contact without the need of first passing the conductor separately through a belonging hole in the terminal cover. This is achieved simply by pushing the conductor down in the recess of the cover and between the tines . of the insulation piercing contact.
  • the U-shape offers an excellent strain relief, which can be improved by additional pressing means. Repair or replacement of the conductors is very easy, since these conductors need not be passed separately through holes in the terminal cover.
  • the terminal cover is lowered on the terminal support containing the inserted terminals.
  • the insulation piercing contacts are first received by the slots in the terminal cover.
  • the contacts thereafter emerge at the upper surface of the cover within a recess.
  • the electrical conductors are placed on the upper surface of the terminal cover in the longitudinal direction across the recesses. Thereafter these conductors can be pushed successively and separately or simultaneously into the recess and between the tines of the insulation piercing contacts.
  • This can be executed with separate tooling formed as a flat strip-shaped anvil, which can press the portion of a conductor stretching across the recess into this recess until in the slit between the two tines.
  • the insulation is cut by the sharp edges of the tines and the core is brought into contact with these sharp edges.
  • the pressing action on the terminals can be executed for all conductors simultaneously by means of a particular cable support, having a lower surface to be placed on the electrical conductor resting upon said terminal cover upper surface and having several conductor pushing anvils extending from said cable support lower surface towards said terminal cover upper surface, each anvil being of sufficient length such that upon lowering said cable support on said electrical conductors, each anvil pushing a conductor portion into each recess in said terminal cover and pushing the U-bottom portion of said electrical con- duetor into the slot between the tines of said bifurcated core piercing contact, each anvil being striplike and having a cross section the largest width extending in longitudinal direction of said recess and the smallest width being smaller than the width of said slot in said bifurcated piercing contact.
  • the contact device of the present invention is particularly suitable for automatically operating assembling means.
  • a conductor has to be repaired or replaced only one conductor needs to be handled.
  • all remaining portions of the contact device can remain in position.
  • the contact between each core and corresponding bifurcated insulation piercing contact is maintained, even when the cable support is removed. Bending each conductor several times for pushing it into the recess of the cover and between the tines of the insulation piercing contact results in a U-shaped bend in the conductor, which by its position in the terminal cover gives a strain relief.
  • This strain relief can be improved by lowering the cable support, which is clamped on the upper surface of the terminal cover.
  • the lower surface of the cable support and the upper surface of the terminal cover may comprise parallel grooves adjacent to each other for at least partly receiving the electrical conductors.
  • Terminals in the terminal support have different distances between the center line of the terminal and the slit between the tines of the bifurcated insulation piercing contact. Terminals having an offset between the slit and their center line are mutually turned with respect to each other 180°.
  • a central terminal can be used, the slot of which coincides with the center line of this terminal, whereas the outer terminals have slits offset with respect to its center line and are rotated 180° with respect to one another.
  • three conductors can be supplied from one side of the contact device to the upper surface of the terminal cover.
  • the DE-B-2 022 029 discloses per se a contact device for terminating one U-bent conductor in one dual insulation piercing contact, mounted in a recess of a housing for this one insulation piercing contact, by means of a pushing device which fits in said recess and comprises a channel for accommodating one upstanding part of the U-bent conductor portion. This device is made for contacting one conductor only and this one conductor should be guided first through the channel in the pushing device.
  • DE-B-2 747 395 also discloses per se a contact device for terminating one conductor in an insulation piercing contact, comprising a housing for this one contact and openings in opposite housing side walls for guiding the conductor and placing it on top of the insulation piercing contact. Thereafter this conductor has to be pushed down between the tines of the insulation piercing contact by means of a particular pushing device. Also here each conductor has to be guided through an opening as in above DE-B-2 022 029.
  • DE-A-2 726 226 discloses a contact device in which separate conductors are placed in channels on top of a combined cable and terminal support, after which core piercing contacts are pushed down onto these conductors into recesses in the cable-terminal support situated below each conductor. For replacing one conductor each insulation piercing contact first has to be removed.
  • Each terminal consists of an upper portion 1, an intermediate portion 2 and a lower portion 3.
  • the terminal may consist of a U-shaped bent electrically conducting sheet. The two parallel sides of this bent sheet are elongated above and below and connected with one another by means of the connection strip 4 in the intermediate portion 2.
  • the elongated upper portions constitute the bifurcated insulation piercing contacts, each consisting of a pair of upstanding tines 5 and 6 respectively, separated from one another by a slit 7.
  • the edges of the tines 5 and 6 defining the slit 7 are sharpened such that upon pressing an insulated conductor from above into the slit 7 the insulation will be cut and the sharp edges of the slit 7 will dig into the core of the electrical conductor. This results in an extremely reliable contact between the core and the terminal.
  • FIGS. 1, 4 and 5 show in the upper portion two parallel bifurcated insulation piercing contacts.
  • one or more bifurcated insulation piercing contacts can be used, however, in the present invention usually two bifurcated insulation piercing contacts are used.
  • FIGS. 6, 12 and 13 show as an example one bifurcated insulation piercing contact per terminal. In FIG. 1 two insulation piercing contacts per terminal are used.
  • connection strip 4 of the intermediate portion 2 is offset to the right over a predetermined distance with respect to the right-hand edge of the side surfaces, so that a shoulder or support base 8 is obtained. Upon positioning a terminal in the terminal support 10 this shoulder will come to rest on a cam in the recesses 11 of the terminal support 10. At the opposite edge of the intermediate portion 2 a sharp protruding barb 9 is formed, which upon positioning in the recess 11 will dig in the material of the side of the opening, so that the terminal cannot be drawn or fall out of the recess.
  • each terminal comprises two contact terminals 12, 13 approaching each other for connecting a further conductor.
  • These contact terminals as a matter of course need not be embodied as shown and also may form part of the intermediate portion 2.
  • the difference between the terminals of FIGS. 2, 4 and FIGS. 3, 5 respectively is that the bifurcated core piercing contacts in the terminal of FIGS. 2 and 4 are displaced with respect to the center line of the intermediate portion 2.
  • the slit 7 in FIG. 2 is situated to the left with respect to the center line over a distance determined by the pitch between recess 11 in longitudinal direction divided lJy the number of rows in the transverse direction of the connector.
  • Upon positioning these terminals in the terminal support 10 one pair of each set is turned over 180°, so that the bifurcated insulation piercing contacts are displaced to the left or to the right with respect to the longitudinal direction of each row of recesses 11.
  • the shape of the intermediate portion 2 is so adapted to the shape of the recesses 11, that the terminal fits closely in these recesses.
  • these recesses are shown having rectangular cross sections.
  • the cross section of the intermediate portion 2 will be likewise rectangular. This can be seen in FIG. 6.
  • FIG. 6 shows the component portions of a contact device of the present invention in an exploded view.
  • the device consists of the terminal support 10, the terminal cover 14 and the cable support 15.
  • the component portions 10, 14 and 15 are drawn above one another, such that upon lowering each portion will take the necessary mutual position.
  • an electrical insulated conductor to be connected is shown having an insulating sheath 17 and a core 18.
  • the terminal support 10 consists of a plastic block having three rows of equi-spaced square or rectangular recesses 11 in this shown embodiment.
  • the pitch between these recesses which means the distance between the center lines of the recesses 11 which are placed behind each other and next to each other is as usual in this kind of contact devices 2.54 mm or 0.100 inch. This measure is mainly standardized and is used in the U.S.A. and in Europe.
  • Between the recesses 11 lands 19 are formed, having equal width, as long as the recesses 11 are of a rectangular cross section. The upper surfaces of these lands function as support for the terminals as shown in FIG. 1, where the shoulders 20 rest upon the upper side of the lands 19 between the recesses 11.
  • Terminals according to FIGS. 2 and 3 are positioned in the middle row of the shown recesses i.e. of the rows of recesses running parallel to grooves 21 in terminal cover 14.
  • a terminal according to FIG. 3 is introduced, whereas at both sides hereof terminals according to FIG. 2 are introduced, turned 180° with respect to each other.
  • the barbs 9 dig in the material of the walls between the recesses, so that the terminals are kept firmly in position.
  • the recesses in FIG. 6 are of square cross section, however, the invention is not restricted to this cross section.
  • the cross section likewise can be circular or elliptical, in which case as a matter of course the intermediate portions 2 of the terminals have to be adapted to this modified cross section, such that the terminals cannot rotate in the recesses about their center lines.
  • terminal cover 14 is shown partly in cross section above the terminal support 10.
  • the cover 14 is provided at the upper side with parallel grooves 21 having such cross section that the round outer surface of each conductor is supported over a part of the periphery.
  • Three parallel grooves 21 are positioned within the distance between two recesses 11, seen transversely to the direction of the grooves.
  • a recess 22 emerges into, each groove 21.
  • a channel or slot 23 emerges in the lower end of the recess 22.
  • Slot 23 emerges also in the lower surface of the terminal cover 14.
  • the recess 22 is of such depth that the upper parts of the two tines 5 and 6 together with slit 7 inbetween are received in the recess 22, sufficiently high in order to obtain a good contact between core 18 of conductor 16 after pushing down a conductor portion in the recess 22 and between the tines 5 and 6.
  • the recess 22 is of angular shape at the bottom. However, this bottom can also be rounded.
  • the terminals are positioned in a manner shown in the recesses 11 of the terminal support 10. In FIG. 6 three of the recesses are filled only, but it will be obvious that the invention is not restricted to this shown example.
  • the terminal cover 14 is lowered on the upper surface of the terminal support 10 upon which all bifurcated insulation piercing contacts will slip into the corresponding slots 23.
  • each anvil 25 Upon lowering the cable support 15 on the terminal cover 14 each anvil 25 is conducted into a corresponding recess 22 and into the slit between the tines of the contact.
  • the front of the anvil 25 forms a rounded hollow cylindrical support surface 26 for the insulating sheath 17 of conductor 16.
  • each anvil comprises an opening 27, having such width that the two remaining pads at both sides of the opening 27 will take a position at both sides of the slit 7 in the bifurcated insulation piercing contact.
  • the cable support 15 Apart from the U-shaped portion of the conductor located in the recess 22 the cable support 15 together with the anvil 25, if used, gives an additional strain relief for conductors 16.
  • the conductors also may be pressed simultaneously by means of a correspondingly shaped tooling in the recesses 22 and slit 7 of the bifurcated insulation piercing contacts.
  • This particular tooling should be provided with anvils 25 in accordance with the number of recesses in which conductors have to be connected. After applying the conductors this particular tooling can be replaced by cable support 15, from which the anvils 25 can be omitted.
  • the terminal support 10 comprising the terminals, the terminal cover 14 lowered on the terminal support 10 and the cable support 15 with conductor 16 placed inbetween can be covered by a dust cover which also may provide additional pressing force between the three plastic parts 10, 14 and 15.
  • This dust cover may be provided with a clamp.
  • the conductors 16 approach from above. Here likewise all conductors are cut simultaneously at 28. In the embodiment of FIG. 13 the conductors also approach from above, but are cut in a surface of the grooves 21, where the bent portions of the conductors 16 leave the recesses' 22.
  • the cable support 15 need only be lifted, after which the conductor to be repaired can be removed by pulling out of recess 22 and out of the bifurcated insulation piercing contact. Thereafter, a new conductor can be applied and connected, after which the cable support 15 can be lowered on the terminal cover again.
  • FIGS. 11 and 12 are preferred above the embodiment of FIG. 13, because all conductors 16 in the embodiments of FIGS. 11 and 12 can be cut in one cutting operating, in which the cutting surfaces are in line with the side of the contact device. Also upon this cutting operation all conductors 16 are supported, at least in the embodiment of FIG. 11.
  • a dust cover is used, consisting of two halves 29. These halves 29 are pressed together and grip around the terminal support 10, terminal cover 14 and cable support 15 and keep these parts clamped together. Conductors 28 are guided out through the shown pipe, also consisting of two halves 30. As a matter of course the number of conductors is not restricted to three as shown.
  • the contact device of the present invention can be used with cables of different design. In case of flat cables each conductor or wire needs firstly to be separated.
  • the core 17 can be solid, but also may be a stranded type.
  • the configuration and dimension of the contact device of the present invention is adapted to a DIN 41612 connector system. However, there is enough design freedom within the scope of the present invention to produce connectors with different dimensional sizes and numbers of positions or recesses in one or more rows.
  • the invention is not restricted to a contact device having only three recesses placed behind each other in one row.
  • the invention can be used throughout where space limitations exist caused by high density of connections, conductors and terminals.
  • these problems are solved by moving the separate conductors from a flat surface downwardly in the shape of a U, below the upper surface of the terminal cover 14 and pressing the conductors in the lower portion of the recess between the tines of the bifurcated insulation piercing contacts. Between these adjoining bifurcated insulation piercing contacts-sufficient insulation exists by turning these bifurcated insulation piercing contacts of the different terminals with respect to the center line of the terminals over 180°. This likewise facilitates the repair of separate conductors.
