Definitions

  • the invention is based on a multi-pole plug device according to the preamble of the main claim.
  • a known plug device according to DE-A-30 23 313 the flat receptacles arranged in three parallel rows in a contact carrier are locked in the unlocking and locking position of the common locking plate with a latching tongue behind a latching edge of the contact carrier.
  • the flat receptacles are additionally secured by the plate.
  • the disadvantage here is that a complicated injection mold with interlocking needles is required to produce the locking edge designed as an undercut and thus the contact carrier. Such complicated tools are relatively susceptible to repairs.
  • plug-in devices are required, in which 50 and more individual plug-in connections are combined, which can be plugged in or unplugged in one go.
  • the disadvantage here is that the plug devices require more and more space, which is very limited, especially in the installation space of motor vehicles.
  • the invention has for its object to provide a multi-pin connector of the type mentioned, which can be manufactured with simple tools and which can be provided with smaller connector parts to save space.
  • the contact carrier can hold more connector parts in the form of smaller box-shaped flat receptacles while maintaining the same size and manages with spring chambers with smooth walls but with a smaller cross section.
  • the spring chambers and thus the contact carriers can be manufactured more easily and with simpler tools. Such tools are much less susceptible to repair, so that they are suitable for economical large-scale production.
  • the plugs can only be used by changing the contact carrier for multi-pole plug devices with the desired number of poles.
  • the flat receptacles can be held and secured in the contact carrier solely by the plate in its unlocking and locking position.
  • the measures listed in the subclaims permit advantageous developments of the plug device specified in the main claim. It is particularly advantageous to provide the openings of the plate with projections and / or to use edge sections of the openings such that the latching tongue and / or parts of the edge of the box-shaped section of the flat receptacles in the unlocking and / or locking position of the plate in the direction of insertion facing the plate side.
  • the connector parts do not only have to be arranged in rows according to size. Larger and smaller plug parts can also be mixed in one or more rows.
  • FIG. 1 shows a plug of a multi-pole plug-in device, partly in longitudinal section
  • FIG. 2 shows a small flat receptacle with a box-shaped section in a front view in a contact chamber of a first exemplary embodiment of the contact carrier in the unlocked position of the plate

  • FIG. 4 5 shows the small receptacle in the same position in side view
  • FIG. 6 shows a section along the line VI-VI in FIG. 3 in a simplified representation
  • FIG. 7 shows a section along the line VII-VII in FIG.
  • Figure 8 shows a cross section through a second embodiment of the contact carrier with a row of small and two rows of larger flat receptacles in the unlocked position of the plate
  • Figure 9 shows a partial cross section through a multi-pin connector with the contact carrier according to Figure 8, in de m a row of small and two rows of larger flat receptacles are arranged
  • FIG. 10 shows a third exemplary embodiment of the contact carrier with a partial cross section through a row with mixedly arranged small and large flat receptacles in the unlocked position
  • FIG. 11 the exemplary embodiment according to FIG. 10 in the locked position.
  • a multi-pole plug device (FIG. 9) has a plug 1 and a plug strip 2, which is provided with flat plugs 3 and is arranged on the cover 4 of an electrical switching device (not shown in more detail).
  • the connector 1 has a first embodiment of a contact carrier made of insulating plastic.
  • the contact carrier 5 consists of a lower part 6 and an upper part 7.
  • the parts 6 and 7 are detachably connected to one another in a manner known per se and not shown in detail.
  • the contact carrier 5 of essentially rectangular cross-section, three rows of a plurality of spring chambers 8 lying parallel to one another are formed.
  • a securing plate - hereinafter referred to as plate 9 - is slidably arranged transversely to the rows of spring chambers 8.
  • the plate 9 has 7 openings 10 corresponding to the spring chambers 8 in the lower and upper part.
  • small flat receptacles 11 are used.
  • the flat receptacles 11 have a contact section with two spring arms 12. This is followed by a box-shaped section 13.
  • a latching tongue 15 is formed at an angle on a wall 14 running perpendicular to the spring arms 12.
  • the detent tongue 15 projects somewhat with its free end over the edge 16 of the box-shaped section 13 and protrudes somewhat on the circumference of the box-shaped section 13.
  • a constricted locking section 17 of the flat receptacle 11 borders on the edge 16 of the box-shaped section 13.
  • the locking section 17 is followed by an inner fastening section 18 for the stripped end of an electrical line which is known and not shown in detail.
  • the inner section 18 merges into an outer fastening section 19 which is attached to the end section of the insulation of the line (not shown) in a manner known per se.
  • FIGS. 2, 3 and 6 show the mounting position of the plug 1, in which the flat receptacles 11 struck on the assigned line ends and designed as micro-timers are inserted into the assigned spring chambers 8.
  • Each flat receptacle 11 is pushed so far into the lower part 6 by the upper part 7 and the plate 9 that the spring arms 12 and the box-shaped section 13 are completely accommodated in the lower part 6.
  • the constricted locking section 17 then extends through the opening 10 of the plate 9, while the fastening sections 18 and 19 are received in the upper part 7 of the contact carrier.
  • the openings 10 of the plate 9 have a projection 20 projecting into the opening 10, behind which the latching tongue 15 engages when the flat receptacle 11 is correctly inserted into the spring chamber 8 of the contact carrier 5.
  • the flat receptacles 11 are then already held in the contact carrier 5.
  • the latching surface of the projection 20 lies in one plane with the side 21 of the plate 9 pointing in the direction of insertion and shown in the drawing as the underside.
  • 22 denotes the center line of a row of spring chambers 8 with flat receptacles 11 - here micro-timers - of which a chamber 8 is shown with a flat receptacle 11 and the section of plate 9 surrounding it.
  • the plate 9 is transverse to the center line 22 of the row of flat receptacles 11 for further assembly of the plug 1 - only one of which is shown - Pushed into the locking position according to Figures 4, 5 and 7.
  • the plate 9 then lies with its side 21 on a section of the edge 16 and the projection 20 of the plate 9 releases the latching tongue 15 and for this purpose lies with the side 21 on another section of the edge 16 of the box-shaped section 13 of the flat receptacle 11.
  • the side 21 lies against opposite sections of the edge 16 in order to prevent the flat receptacle 11 from tilting.
  • the second exemplary embodiment of a contact carrier 23 according to FIG. 8 has, in addition to a row of spring chambers 8 with the small flat receptacles 11, two rows of spring chambers 24 running parallel to the first row, one of which is only indicated.
  • the spring chambers 24 are made larger to accommodate larger flat receptacles 25 than the flat receptacles 11.
  • the section of the spring chamber 24 in the lower part 26 of the contact carrier 23 can therefore be provided with an undercut 27, behind which protrudes on a wall of the box-shaped section 28 of the receptacle 25 first latching tongue 29 engages.
  • a second latching tongue 30 on the box-shaped section 28 is supported on the wall of the spring chamber 24 opposite the undercut 27.
  • the wall may be provided with an insertion bevel 31 in its end section facing the plate 9.
  • the plate 9 is pushed transversely to the rows of spring chambers 8 and 24 in the direction of arrow 32 until the fixing tabs 33 and 34 abut on the upper part of the contact carrier 23 and on the plate 9.
  • the small flat receptacle 11 is then again held securely in the contact carrier 23 by the plate side 21 resting against sections of the edge 16 of the box-shaped section 13.
  • the larger flat receptacles 25 are additionally secured to the undercut 27 of the lower part 26 of the contact carrier 23 by the plate 9.
  • An edge section 35 of the opening 36 of the plate 9 lies with the side 21 on an edge section 37 of the box-shaped section 28 of the larger flat receptacle 25.
  • the edge section 35 lies opposite the undercut and thus also overlaps the second latching tongue 30 of the flat receptacle 25 Larger blade receptacle 25 also held in the contact carrier 23 against tilting.
  • the larger spring chambers 24 for the larger flat receptacles 25 can also be produced more easily with an undercut 27, since there is more space and therefore the tools for this are coarser and therefore more durable and less prone to repair.
  • the partial cross section shown in FIG. 9 through part of a multi-pole plug device shows the contact carrier 23 with a row of small flat receptacles 11 and with two rows of larger flat receptacles 25.
  • the contact carrier 23, 26 with the plate 9 in the locking position is inserted into a housing 38 made of insulating plastic .
