Definitions

  • the invention relates to a contact device for transmitting strong electrical currents, having a cylindrical contact pin and a contact spring socket receiving the pin, on the cylindrical inner wall of which a plurality of resilient contact elements extending essentially axially parallel is provided.
  • the invention has for its object to provide a contact device of the type mentioned, in which an insertion of the contact pins in the contact spring bushing is possible even if no exact axial alignment of the contact pin and contact spring bushing is given during insertion.
  • the contact device according to the invention in which this object is achieved, is essentially characterized in that, in order to bridge greater tolerances between the contact pin and the contact spring bushing, the latter is supported both axially and radially by spring contact elements in an outer socket body. It has been shown that when using a contact device designed in this way, a contact pin is properly received by the contact spring bushing even when it is supplied with a greater axial lateral offset relative to the contact spring bushing.
  • the inner contact spring bushing which is practically floating in the outer socket body, can be moved into the lateral position required for receiving the contact pin without impairing the current transferability. A lateral offset of ⁇ 1 mm can be easily compensated for. Nevertheless, the plug-in device is pluggable under load.
  • a particularly simple structure of the contact device is obtained if the outer socket body is pot-shaped and has contact spring elements on its cylindrical jacket and a contact spring washer on its bottom.
  • the outer socket body is formed in two parts and one cylindrical jacket and a separate, connectable to the jacket base and that the cylindrical jacket is provided on its front edge facing away from the bottom with a support for the spring spring contact of the contact spring washer serving radially retracted flange.
  • the cylindrical jacket can easily be equipped with the contact spring elements before the contact spring bushing is inserted and fixed after inserting the contact spring washer by fixing the bottom to the cylindrical jacket within the outer socket body.
  • the radially retracted flange on which the contact spring bush is supported also serves as spark protection when the contact device is disconnected under load.
  • connection of the bottom of the socket body to the cylindrical jacket by means of a screw thread has proven to be favorable for convenient assembly.
  • the contact spring washer provided on the bottom is advantageously designed as a meandering star washer.
  • an axial annular groove is provided in the region of the radially inwardly drawn flange for receiving the front ends of spring wire sections evenly distributed on the cylindrical jacket, the rear ends of which are in an annular gap between the cylindrical jacket and a protrude axially protrusion of the bottom fixed to the cylindrical jacket of the outer socket body, and if the socket body is provided with two radially pressed-in ring beads at a distance, against which the spring wire sections rest under elastic curvature.
  • each flat recess is equipped with a contact ring band which comprises a plurality of resilient contact fingers angled from the plane of the web by approximately 180 °.
  • a conventionally designed i.e. in a manner not shown on its cylindrical inner wall with a plurality of contact springs equipped contact spring bushing 1, which serves to receive a contact pin 2, in an outer socket body 3, as indicated by arrows, both axially and radially spring-mounted.
  • This socket body 3 is cup-shaped.
  • contact spring elements 4 On its cylindrical jacket, it is equipped on the inside with contact spring elements 4 which ensure the radial suspension, and on its bottom there is a contact spring washer 5 for axial suspension.
  • the outer socket body 3 is formed in two parts and comprises a cylindrical jacket 6 and a bottom 7 connectable to it.
  • the cylindrical jacket 6 On the front edge facing away from the bottom 7, the cylindrical jacket 6 is provided with a radially retracted flange 8 which supports the spring washer of the contact spring washer 5 standing contact spring socket 1 is used.
  • the bottom 7 can be connected to the cylindrical jacket 6 by pressing. A detachable connection by means of a screw thread 9 is more favorable.
  • the contact spring washer 5 provided on the bottom is designed in the manner shown in FIG. 2 as a meandering star washer, the central area of which is embossed out of the plane of the disk edge area.
  • an axial annular groove 10 is provided in the region of the radially inwardly drawn flange 8, which serves to receive the front ends of spring wire sections which are evenly distributed on the cylindrical jacket 6 and form the contact spring elements 4.
  • the rear ends of the spring wire sections protrude into an annular gap 11 between the cylindrical jacket 6 and an axial projection 12 of the bottom 7.
  • the socket body 3 is provided with two annular beads 13, 14 which are radially pressed in at a distance. The spring wire sections, which are transferred in an elastically curved state, are supported on these ring beads.
  • the variant according to FIG. 3 comprises a contact spring mat forming the contact elements 4, in which the ends of the spring wire sections are fixed, for example by soldering, on webs running at a distance from one another and parallel to one another.
  • the webs are connected by means of spacer strips with which they are expediently formed in one piece. In a subsequent work step, the spacer strips are deformed, the spacing of the webs being reduced with elastic curvature of the spring wire sections.
  • the manufacture of such a contact spring mat is the subject of the earlier patent application P 36 15 915.8.
  • each contact ring band 16 is punched out of a contact spring plate.
  • the contact fingers 17 formed in the manner of a comb proceed from a common web 18 and are bent backwards by 180 ° relative to the latter. Your from the contact fingers 17 stamped contact projections 19 come to rest on the outer wall of the contact spring bushing 1.
  • This embodiment is also distinguished by the possibility of being able to insert the associated contact pin 2 into the contact spring bushing 1 in a laterally axially offset position, as indicated by dash-dotted lines in the drawing.
