Definitions

  • the invention relates to a bus line which is equipped with such plugs.
  • a bus line serves for the simultaneous control of several consumers or control units, for example in a motor vehicle, but the invention is not restricted to this application.
  • a bus line not only are the ends provided with a plug, but taps are possible anywhere between the ends.
  • taps it is known, for example from DE-C-33 33709, to design such taps in the form of a ribbon cable, the individual conductors of the tap also each individually with the respective stripped wire the bus line must be mechanically and electrically connected.
  • Such taps are far too expensive for bus lines in mass production; it is therefore desirable to design the tap in the form of a plug, the contacts of which can be connected to the line wires of the flat cable at the same time as a stop operation.
  • a ribbon cable connector which essentially corresponds to the structure described at the beginning.
  • the ribbon cable is clamped between the base body and the cover, and the cable cores can all be struck at the same time via insulation displacement contacts by pressing a cover onto a base body.
  • the cover is provided in a U-shape with side arms in such a way that these side arms overlap the base body and latch on opposite outer sides of the base body.
  • it is proposed there to hold the cover which has been pre-locked in an intermediate position on the base body in an assembly device and to insert the ribbon cable into the space between the cover and base body, it being guided between the side arms of the cover and, if appropriate, in the assembly device.
  • the aim of the invention is to design a bus line connector of the type mentioned at the outset in such a way that it can be attached to a ribbon cable in a simple manner, the cable being reliably guided in the correct position to the insulation displacement contacts without additional aids.
  • the connection between the base body and the cover should be designed so that large holding forces are generated, that the connection of the cover and base body is not endangered when pulled out of a mating connector and that the latching connection even withstands high tensile forces on the ribbon cable.
  • the base body therefore has a U-shaped ribbon cable holder, between the side walls of which the cable is guided.
  • This guide is therefore on the same part that also carries the contact elements with the insulation displacement zones.
  • the clamping cover is guided and locked between the side walls of this ribbon cable receptacle, that is to say the base body, so that it is then sunk between these side walls. So when you pull the plug out of a mating plug, you grip with the fingers not on the cover, but directly on the base body, so that the snap connection is not stressed.
  • This locking connection is particularly stable due to the sinking of the clamping cover between the U-shaped side walls of the base body, so that it can withstand strong tensile loads on the cable.
  • the side arms of the cover are provided with a U-profile and thus reinforced, but the latching connection cannot be so stable because the elongated base section of the cover there with its low profile Thickness of an expansion of the side arms is only able to offer little resistance.
  • the side arms of the ribbon cable guide are molded onto the base body, which due to its dimensions, which it already needs to accommodate the contact elements, is not deformable and thus also gives the side arms a corresponding moment of resistance to deformation.
  • At least one holding spike is formed on the base body or on the cover in the region of the ribbon cable receptacle, which holding rod is oriented perpendicular to the cable plane and which forms the insulating web of the ribbon cable pierced between two wires and snapped with a hook-shaped end in an undercut recess of the cover or the base body.
  • a holding skewer is provided in the edge regions of the ribbon cable receptacle in the longitudinal direction of the cable in front of and behind the insulation displacement zones between two ribbon cable cores and with its hook-shaped end can be locked in the lid. This provides additional strain relief on both sides of each Line wire and on both sides of each insulation displacement connection.
  • additional latching hooks can be integrally formed on the legs of the side walls projecting inward to receive the ribbon cable, said latching hooks engaging with latching lugs of the cover in the area of the four outer edges. This also generates additional holding forces at the corners of the lid, which cannot come into engagement with the locking groove between these legs because of the U-shaped projecting side legs of the side walls.
  • the holding skewers mentioned not only have the function of improving the snap-in connection between the base body and the cover after mounting and absorbing tensile forces in the longitudinal direction via the perforation of the insulation, but they also serve to guide and align the cable cores with respect to the insulation displacement zones of the cable during attachment Contact elements.
  • a further improvement in the cable routing when attached can be achieved in that the cover also has guide arms which guide the ribbon cable on two opposite sides and are guided in the U-shaped side walls of the ribbon cable receptacle. The guide arms of the cover and the side walls of the base body are thus nested. During assembly, it is therefore possible to first insert the ribbon cable either between the guide arms of the cover or between the side walls of the ribbon cable receptacle and then to press the two parts together.
  • windows are formed in the side legs of the side walls of the ribbon cable receptacle, which are aligned with the locking groove between these side walls.
  • the manufacture of the base body is facilitated by this window design; through this window a slide for the undercut locking groove can be demolded without affecting the stability of the side legs.
  • the bus line connector shown in the drawing consists of a base body 1 and a clamp cover 2 which can be locked therein, both of which are formed from insulating material. Between these two parts, a ribbon cable 3 is attached, which in the example shown in FIG. 1 has three line wires 31; these are surrounded by an insulating sleeve 32 and connected to one another by insulating webs 33 in one plane.
  • the connector body 1 contains, for example, three contact elements 4, which are largely covered in the drawing, corresponding to the number of conductor wires of the ribbon cable. They each form plug sockets or pins within the housing and are open in recesses to the plug end 11 of the base body; With this plug end 11 in front, the base body 1 can be inserted into a mating connector 5 (see also FIG 6). At the upper end, each of the contact elements 4 forms two insulation displacement zones 41, one behind the other (see also FIG. 2), which are exposed in a U-shaped ribbon cable receptacle 12 of the base body. So that each wire 31 is contacted via two insulation displacement zones 41 and thus twice.
  • the ribbon cable receptacle 12 is open at the top in a U-shape and is delimited by two symmetrical side walls 13, which in turn have a U-shaped profile by having side legs 14 projecting inwards to the ribbon cable recess (see FIG. 4).
  • the two side walls 13 each have an undercut locking groove 15, which extends over the entire width between the two side legs 14.
  • the clamping lid 2 corresponds in width ( Figure 1) to the width between the side walls 13, while in its depth, i.e. in the longitudinal direction of the ribbon cable 3, which corresponds to the depth of the base body in the region of the ribbon cable receptacle. ( Figure 2).
  • the clamping cover In the corner areas 21 it is recessed corresponding to the side legs 14 of the ribbon cable holder, so that it can be used between the U-shaped side walls.
  • the clamping cover On the long sides, the clamping cover has locking ribs 22, which can be locked in the locking grooves 15 of the side walls.
  • additional locking hooks 16 are formed on the side legs 14 of the side walls 13, under which molded locking lugs 23 snap into the corner regions 21 of the clamping cover.
  • the side legs 14 also each have a window 17 corresponding to the cross section of the locking groove 15. These windows are used for easier removal from the mold when the locking groove 15 is formed in the injection mold. With these windows and due to the remaining pillars 18 on the side legs, the high stability of the side walls 13 is ensured despite the good demoldability, which after locking the Locking grooves 15 with the locking ribs 22 and the locking hook 16 with the locking lugs 23 ensure a very high resistance moment of the struck plug against tensile forces from the ribbon cable.
  • the strength of the connection between base body 1 and cover 2 is further increased by spits 19, which are arranged in pairs at the front and rear ends (in the longitudinal direction) of the ribbon cable receptacle in a grid between two insulation displacement zones 41, drill through the insulating web 33 between two cable cores 31 and with hook-shaped ends 19a penetrate through plug-in channels 24 of the clamping cover 2, where they then snap into transverse webs 25 and additionally lock the cover.
  • spits 19 which are arranged in pairs at the front and rear ends (in the longitudinal direction) of the ribbon cable receptacle in a grid between two insulation displacement zones 41, drill through the insulating web 33 between two cable cores 31 and with hook-shaped ends 19a penetrate through plug-in channels 24 of the clamping cover 2, where they then snap into transverse webs 25 and additionally lock the cover.
  • clamping cover 2 is also U-shaped with guide arms 26 molded downward, these guide arms 26 being fork-shaped at the ends. These guide arms 26 slide when the clamping cover 2 is inserted into the ribbon cable receptacle 12 between the side legs 14 of the side walls 13.
  • the clamping cover 2 also has plug-in channels 28 for receiving the insulation displacement zones 41 of the contact elements 4.
  • the inner sides 27 of the guide arms 26, like the inner sides of the latching hooks 16, have a spacing on the side walls 13 which corresponds to the width of the ribbon cable 3.
  • the side arms 13 are higher than the skewers 19, so that the ribbon cable 3 is guided in any case during the striking process, be it that the ribbon cable is first inserted into the ribbon cable receptacle 12, namely on the skewers 13 and between the side walls 13 or be it that the ribbon cable is first placed in the lid between the guide arms 26.
  • the clamping cover 2 is pressed into the ribbon cable receptacle 12 of the base body 1
  • the ribbon cable is guided both between the side arms 13 of the base body and between the guide arms 26 of the cover.
  • FIGS. 5 and 6 also show in two detail sections the locking of the skewers 19 on the locking webs 24 of the base body and the locking of the locking ribs 22 in the locking grooves 15 of the side walls.
  • a bus line is also shown schematically in FIG. 7, which consists of a ribbon cable 3 with a row of attached plugs 10.
  • a mating connector 5 is shown schematically, which has a plug opening 51, into which a plug 10 can be inserted with its plug side 11.
  • the base body as can be seen in FIGS. 1 to 6, can be gripped on the side walls 13.
  • these side walls 13, as can be seen in FIGS. 1, 3 and 6, are thickened towards the free end of the ribbon cable holder and provided with transverse ribs or steps 13a.
