Definitions

  • the invention relates to a connector arrangement for a plurality of individual plugs with individual housings and in each case at least one contact pin, the individual plugs being connectable in a holder to form a uniformly manageable plug.
  • Such connector arrangements are particularly intended for the connection of body electrodes to medical diagnostic or treatment devices.
  • Such connector arrangements are known for example from DE 30 12 174 C2 and DE 38 07 645 A1.
  • the individual plugs which have an essentially rectangular individual housing, are inserted or inserted into holders which are open in the longitudinal direction on both sides. Due to a positive connection between the holder and the correspondingly designed individual housings of the individual plugs, the individual plugs are fixed in the holder in the longitudinal direction.
  • the individual plugs In the embodiment disclosed in DE 38 07 645 A1, the individual plugs have grooves which are flush with one another and into which a foldable web of the otherwise one-piece holder engages in order to ensure axial fixation.
  • the holder is provided with specially shaped chambers, the shape of which matches the outer contour of the individual housing of the individual plug.
  • the holder has a hinged lid. With the lid open, the individual plugs can be inserted into the chambers of the holder from above.
  • the holder has a tab pointing in the direction of insertion, which cooperates with a corresponding recess in the counterpart to produce an anti-rotation device.
  • the connector arrangement is locked in the counterpart by means of locking grooves which are formed on the contact pins of the connector arrangement and cooperate with corresponding locking elements in the counterpart.
  • the individual connectors receive certain different colors, depending on the placement of the associated body electrodes on the body.
  • the individual connector housings have to be manufactured with differently colored materials, which naturally increases the manufacturing effort.
  • the problem underlying the invention is to reduce the effort in the manufacture and / or storage of the connector arrangements of the type mentioned at the outset.
  • a connector arrangement of the type mentioned at the outset is characterized in that the individual housing of each individual connector is surrounded by a cylindrical sleeve with a rectangular cross section, which is open on one end-side insertion side and an opening for passage in an end wall on the opposite side of the at least one contact pin of the single plug.
  • the sleeve can preferably be snapped onto the individual housing of the associated single plug, for example by providing a recess in a jacket side into which a latching projection of the single plug can be snapped.
  • each individual housing carries a sleeve, the disadvantages of the known connector arrangements mentioned above can be considerably reduced.
  • sleeves of different wall thicknesses can be pushed onto the individual plugs, it is only possible to adapt to different counterparts from different manufacturers with the same individual plugs, which may be connected to body electrodes, only by using a suitable sleeve.
  • the sleeves of the connector assembly are made of different colored material, there is no need for the individual connector housings to be colored differently.
  • the sleeves can preferably be snapped onto the individual housings of the individual plugs.
  • the sleeve can expediently have a recess in a lateral surface into which a latching projection of the individual plug can be snapped.
  • the locking projection is preferably designed in the manner of a barb to ensure a secure connection.
  • the recess can be formed by a window into which a locking means of the holder can also engage from the outside.
  • the wall of the sleeve in the region of the window is preferably stepped such that the window area from the outside is larger than the window area from the inside, which is used for the latching connection to the individual plug.
  • the individual housings of the individual plugs and the inner contour of the sleeve adapted to them can have any shape, that is to say, for example, round or oval or polygonal in cross-section, but a cross-sectional configuration of the individual plugs and the inner contour of the sleeves is preferred.
  • the plug arrangement according to the invention is preferably used for single plugs with two contact pins and single housings with a rectangular cross section with large and small jacket sides.
  • the recess of the sleeve is preferably located on a small side of the jacket. In this case, it is advantageous to design the individual plugs with the large jacket sides lying one against the other in a holder.
  • FIG. 1 shows a single plug 1 with a rectangular housing 2 with large outer surfaces 3 and small outer surfaces 4 and two contact pins 5.
  • the individual housing 2 is located at the end of a cable 6 to which the single plug 1 is connected.
  • FIG. 1 a shows a view of the single plug on the large lateral surface 3
  • FIG. 1 b shows a view on a small lateral surface 4.
  • a locking projection 7 On the small lateral surface 4 there is a locking projection 7, which has a sawtooth-shaped contour in the manner of a barb.
  • FIG. 2 shows several views of a sleeve 8 which has a rectangular cross section and is open on one end face 9. On the opposite end face 10, the sleeve has through openings 11, the shape of which is adapted to the shape of the contact pins 5.
  • the sleeve 8 also consists of large outer surfaces 12 and small outer surfaces 13, FIG. 2a showing a view of a large outer surface and FIG. 2b) showing a view of a small outer surface.
  • the small lateral surface 13, to which the view according to FIG. 2 b) is directed, has a window-like through opening 14, the size of which is adapted to the size of the locking projection 7 of the individual housing 2.
  • the through opening 14 is stepped toward the outside and forms an outer window surface 15 which is larger than the inward-facing window surface formed by the through opening 14.
  • FIG. 2 a) and the views according to FIG. 2 c) on the end face 10 and according to FIG. 2 d) on the end face 9 illustrate that the sleeve 8 on a small lateral surface 13, which is not provided with the passage opening 14, towards the end face 9 has a projection 16 formed by a step.
  • Figure 3 illustrates in an enlarged and sectional view that the through opening 14 is stepped outwards and has a larger window area to the outside.
  • FIG. 4 shows three views of the individual plug 1 with the snapped-on sleeve 8.
  • the position of the contact pins 5 defines an insertion direction pointing towards the free end of the contacts 5 and clarifies that the projection 16 of the sleeve 8 lies in the insertion direction at the rear.
  • the enlarged detail shown in FIG. 5 shows that the latching projection 7 of the plug housing 2 is only in the through opening 14 up to the gradation, that is to say does not protrude into the region of the enlarged window area 15.
  • the locking projection 7 prevents accidental pulling out of the Single plug 1 from the sleeve 8.
  • the further insertion movement of the single plug 1 in the sleeve 8 is prevented by the end wall 10 provided with the through openings 11 and otherwise closed.
  • Figure 6 illustrates that in the illustrated embodiment, five individual plugs 1 with their individual plug housings 2 can be put together to form a compact block in which the individual housings 2 with the snap-on sleeves 8 with the large lateral surfaces 12 abut one another and are put together in alignment with one another.
  • the individual plugs 1 can be received by the holder 17 shown in FIG. 7 and thus become a uniformly manageable plug arrangement.
  • the holder 17 consists of a base 18, two side walls 19 and a cover web 20 which is hinged to a side wall 19 and which can be latched into a recess 22 in the other side wall 19 in the closed state of the cover 20 with a latching lug 21.
  • the holder is open on the two end walls 23, 24.
  • the articulation of the cover 20 on the side wall 19 is achieved by a toothed design of the two parts and the insertion of a hinge pin 25.
  • FIG. 7 a shows a top view of the open end wall 23 in a partially open position of the cover 20
  • FIG. 7 b) shows a top view of the side wall 19 provided with the recess 22
  • FIG. 7 c) shows a top view of the one provided with the hinge pin 25 Side wall 19.
  • FIG. 7 d) shows a top view of the cover 20, which in the exemplary embodiment has lettering and / or color coding for the transmission channels formed with the individual plugs 1.
  • the individual plugs 1 are axially fixed in the holder 17 by elevations 26 on the base 18, the size and position of which is selected such that they engage in the larger window area 15 of the through opening 14 in the sleeve 8. Since the height of the side walls 19 is adjusted to the height of the large lateral surface 12 of the sleeve 8, the sleeve 8 is fixed locally in this way after the cover 20 has been closed.
  • a tab 27 is also attached in the center in the insertion direction at the front, that is to say in front of the front wall 23, and has a latching bead 28 pointing downwards.
  • the tab 27 thus serves both for the rotationally secure positioning of the plug arrangement and for the axial latching of the holder 17 - and thus all the individual plugs 1 in the holder 17 - in the correspondingly designed counterpart (not shown) into which the plug arrangement is inserted.
  • the individual plugs are axially fixed in the counterpart not via the individual plugs 1 or their contact pins 5, but rather via the tab 27 attached to the holder 17.
