Definitions

  • the invention relates to a multi-pin connector according to the preamble of the main claim.
  • Plug connections of this type are known. (Main catalog of the company W.W. Fischer SA, Switzerland, edition 1997). For easy position finding when plugging the plug and socket or coupling, either half-cylinder shells made of metal are to be provided on the plug as well as on the socket / coupling, which, when properly connected, complement one another to form a Noll cylinder surrounding the plug-in connection, or, if they are mixed up, are identical Plug-in connections should be avoided, several partial cylinder shells distributed around the circumference, for example two quarter-cylinder shells on the connector and two quarter-cylinder shells on the socket / coupling (Fischer catalog section L, page 4: Codes for position finding when plugging in).
  • a plug housing made of metal which on the one hand is electrically connected to the cable shielding and which, when plugged together, makes electrical contact with the housing of the socket or the coupling, which is also made of metal.
  • This ground contact for the cable shielding which was previously only possible via the plug housing, is complex and also not optimal in electrical terms.
  • the partial cylinder shells made of metal which are already provided in such plug-in connections for the mechanical position, are simultaneously used for producing the electrical ground contact by a simple, inexpensive modification.
  • at least one additional contact spring element is formed on at least one of the partial cylinder shells on at least one of the longitudinal edges, which produces an electrical transverse contact between the longitudinal edges of the partial cylinder shells in the assembled state.
  • the plug housing is no longer required for the ground contact, it can consist entirely of non-conductive plastic.
  • a plug connection according to the invention is very inexpensive to assemble from a few individual parts and nevertheless a good and safe ground contact connection is ensured in the assembled state.
  • the the Contact spring elements producing transverse contact between the partial cylinder shells can be produced in various ways on the longitudinal edge. In the case of small to medium-sized connector sizes, in which the partial cylinder shells consist of thin spring sheet metal, the contact spring element can be produced by a single longitudinal slot running parallel to the longitudinal edge or by several short longitudinal slots formed one behind the other in the spring sheet metal shell, with the shell formed on one or both sides with the shell connected narrow spring plate web or spring plate webs can be bent slightly outwards.
  • the contact spring elements can consist of multi-folded sheet metal webs, which are worked out through slots in the partial cylinder shells, or it is also possible, if appropriate, to use separate contact spring parts in corresponding edge recesses in the partial cylinder shells.
  • the contact springs are distributed over the partial cylinder shells in such a way that no torsional forces are exerted on the partial cylinder shells used for the position formation when they are plugged together.
  • contact spring elements are provided on only one of the half-cylinders, preferably on that of the plug, on both longitudinal edges. This avoids that when plugging together the half-cylinder shells, which complement a full cylinder, twist in one direction and then no longer have the predetermined orientation between the plug pins and the plug sockets, and therefore no longer guarantee the task of exact position finding when plugging together.
  • a connector additionally equipped with contact springs according to the invention is fully compatible with conventional sockets or connector couplings.
  • FIG. 1 shows a multi-pole plug connection in the pulled-apart state, consisting of a plug and an associated socket
  • FIG. 2 shows in detail the half-cylinder shells used here according to the invention.
  • Figures 3 and 4 show further exemplary embodiments for the formation of the contact spring elements.
  • the plug shown in Figure 1 consists of an insulating material body 2 receiving the contact pins 1, on which a semi-cylindrical shell 3 made of metal is placed. This assembly is inserted into a cylindrical metal connector housing 5. In the assembled state, the front edge of the half-cylinder shell 3 extends almost to the edge of the connector housing 5.
  • the insulating material body 2 with the half-cylinder shell 3 fastened thereon is held in the connector housing 5 by a soldering window sleeve 6, which is held by a collet 7 and a clamping nut screwed onto the connector housing 5 8 is pressed inwards.
  • the connecting cable is inserted through the clamping nut 8 and the collet 7 into the interior of the plug housing, the cable shield made of metal braid is placed over the conical surface 9 of the collet and, in the assembled state, clamped between this conical surface 9 and the conical surface 10 of the solder window sleeve 6.
  • the other end 11 of the solder window sleeve 6 presses on the collar 12 of the half-cylinder shell 3. There is therefore direct galvanic contact between the cable shield and the half-cylinder shell 3.
  • a cylindrical insulating material body with the associated contact sockets 21 is inserted in a cylindrical metal socket housing 20, and a semi-cylindrical shell 23 is again on the insulating material body, similar to the body 2 attached from metal.
  • a coupling housing corresponding to the plug housing 5 is provided and the shielding of the cable connected to the coupling is again galvanically connected to the half-shell 23, similar to the connector.
  • FIG. 2 shows, on an enlarged scale, the interaction of the two half-cylinder shells 3 and 23, which ensure exact positioning of the connector pins 1 relative to the connector sockets 21. Only in the position of the two half-cylinder shells relative to one another shown in FIGS. 1 and 2 can plug and socket or coupling be plugged together and only in this position do the plug pins and plug sockets have their predetermined assignment.
  • At least one contact spring element is formed on at least one of the half-cylinder shells 3 and 23 on at least one of the longitudinal edges.
  • the half-cylinder shell 3 of the plug is made of spring sheet metal and a contact spring 13 is formed on each of its two longitudinal edges 22, which is slightly curved outwards and, in the assembled state, makes contact with the longitudinal edges 22 of the half-cylinder shell 23 of the socket.
  • this contact spring 13 is formed by a longitudinal slot 14 running parallel to the longitudinal edge 22, the resulting narrow web 15, which is connected at both ends to the half-cylinder shell 3, is slightly curved outwards and forms the Contact spring 13.
  • the longitudinal slot 14 could also be open at one end, preferably at the end facing the collar 12, so that a contact spring is attached only on one side to the half-shell 3, but care must then be taken to ensure that when the plug connection is released Spring does not get caught on the counterpart.
  • a plurality of short spring elements that are closed or open on one side could also be formed one behind the other along the longitudinal edge 22.
  • the longitudinal slot 14 or the several successive longitudinal slots could also be filled or covered by an inserted foil element made of metal or by a conductive elastic silicone material.
  • This additional contact spring 13 on the edge of the half-shells ensures good electrical contact between the two when plugged together Longitudinal edges 22 of the half-cylinder shells 3 and 23 are produced and thus a good and defined ground contact between the cable shield and the socket-receiving housing or the cable shield of a coupling.
  • Forming the connector housing 5 from metal is superfluous, it could consist entirely of plastic.
  • the measure according to the invention has the additional advantage that the contact springs 13 expand the two half-cylinder shells 3 and 23 slightly radially and thereby between the cylindrical inside of the metal housing 5 and the outside of the half-cylinder shells 3 and 23 an additional ground contact is made.
  • Figure 3 shows a further exemplary embodiment of the design of the contact spring element 13, which is again formed by a slot 14 in the half-cylinder shell 3 of the connector.
  • the slot 14 is open at the front and this results in a sheet metal web 16 which is only attached to the half-cylinder shell 3 on one side and whose front end in the insertion direction is widened to form a contact 18.
  • this type of contact spring element is only suitable for those plug-in connections in which the positional flow when the plug and socket / coupling are put together is not impaired by the sheet metal web which projects freely towards the front.
  • a design of the contact spring element 13 according to FIG. 4 is more advantageous, since here the open slot in the plug-in direction 19 at the rear, i.e.
  • an increased spring force is achieved in that, by means of two U-shaped slots 30, 31, a multiply folded sheet metal web 32 is worked out of the half-cylinder shell 3, which is connected to the half-cylinder shell 3 at both ends, but nevertheless as a spring element fastened only on one side to the half-cylinder shell 3 acts.
  • the measure according to the invention can be used with the most diverse multipole connectors of any size, even with mixed connectors with coaxial cables, light guides, thermocouples and the like. (Fischer catalog, sections E to G).
