Definitions

  • the invention relates to a connection unit with an insulating mounting frame and with a plurality of resilient pressure contacts arranged on the mounting frame, each pressure contact having a coiled pressure spring which can load a metal contact body with a spring force, and each contact body being connected in one piece to a connector plug or a connector socket .
  • connection unit is known from the German patent DE 102008007744 B3.
  • the pressure contact is formed here by a one-piece stamped part which has a spiral-shaped spring element.
  • spring-loaded pressure contacts are common electrical connection means. They can be used particularly advantageously when electrical modules are contacted blindly and/or when tolerances have to be compensated for when connecting.
  • the object was to create a generic electrical connection unit with a plurality of spring-loaded pressure contacts in a simple and cost-effective manner, which can compensate particularly well for tolerances between units to be contacted.
  • the mounting frame has a hollow cylinder for each pressure contact, which forms a floating space within a peripheral wall, that the floating space is closed off by a cover that is arranged to be axially displaceable on the wall of the floating cylinder, that the pressing spring in the Is arranged inside the cavity and acts with its spring force on the cover, and that the contact body integrally forms a contact disk, which is arranged on the outside of the cover.
  • connection unit according to the invention with reference to the figures. It show the
  • Figure 1 is a plan view of a first embodiment of the connection unit
  • Figure 2 is an exploded view of the connection unit
  • FIG. 3 shows an exploded view of a contact element of the connection unit
  • Figure 4 is a sectional view of the pressure contact of the connection unit
  • Figure 5 is a sectional view of the pressure contact of a second
  • FIG. 6 shows a plan view of the second embodiment of the connection unit
  • FIG. 7 shows an exploded view of a contact element of the second embodiment of the connection unit
  • FIG. 8 shows a top view of a third embodiment of the connection unit
  • FIG. 9 shows a sectional view of the contact element of the third embodiment of the connection unit
  • FIG. 10 is a plan view of a fourth embodiment of the connection unit
  • FIG. 11 shows a sectional view of the contact element of the fourth embodiment of the connection unit.
  • elements that are the same and have the same effect are denoted by the same reference symbols, even if the design is partially different.
  • FIG. 1 shows a first exemplary embodiment of a connection unit designed according to the invention.
  • the connection unit has three pressure contacts 2 which are mounted on a mounting frame 1 .
  • Separating webs 18 are arranged between the pressure contacts 2, the longitudinal edges of which are integrally connected to the mounting frame 1 and thereby stabilize the mounting frame 1 mechanically.
  • FIG. 2 illustrates the structure of a pressure contact 2.
  • the mounting frame 1 forms a hollow cylinder 6 in one piece, which has a wall 7.
  • the cylindrical wall 7 forms a flea space 8 into which a pressure spring 3 is inserted.
  • the pressure spring 3 is advantageously designed here as a simple helical spring.
  • a contact element 4 is connected to each hollow cylinder 6 so that it can move axially and is pressure-loaded by the pressure spring 3 inserted into the space 8 of the cylinder 6 .
  • the construction of the contact element 4 is illustrated by the exploded view of FIG.
  • the contact element 4 consists of a cover 9 made of plastic, a metal contact body 10 and a lamellar ring 14, also made of metal.
  • the cover 9 has a round cover surface 23 along the circumference of which surface sections 24 are integrally formed, which are perpendicular to the Top surface 23 extend.
  • the surface sections 24 form in particular a slot 20 and a plurality of guide grooves 22 .
  • the metal contact body 10 has an approximately circular contact disk 17 and a plug-type or socket-type connection element connected to it in one piece, which is shown in FIGS. 3 and 4 as a blade contact 11 by way of example.
  • the blade contact 11 extends perpendicularly to the surface of the contact disk 17 and is guided through a recess 26 in the cover 9, as a result of which the underside of the contact disk 17 bears against the cover surface 23 at least in sections.
  • the contact body 10 is fixed to the cover 9 by a resilient lamellar ring 14 .
  • the lamellar ring 14 is inserted above the contact disk 17 under three retaining lugs 25 formed on the cover 9 .
  • the lamellar ring 14 has a plurality of resiliently arranged lamellae 15 which extend radially in one piece from this annular section 27 . After assembly above the contact body 10 , the free end sections of the lamellae 15 run towards a bulge 5 integrally formed centrally on the contact disk 17 .
  • FIG. 4 shows a sectional view of a fully assembled pressure contact 2. It can be seen here that the cover 9 has a one-piece molding 29 on the underside of the cover surface 23, which protrudes into the interior of the cavity 8 of the cover 9. The projection 23 thus creates a relatively long, channel-like recess 26 in which the blade contact 11 is held in a stable and tilt-free manner.
  • the effected by the pressure spring 3 axial displaceability of the contact element 4 and thus the contact body 10 also creates a tolerance compensation in the axial direction.
  • FIGS. 5 A second exemplary embodiment of the connection unit is shown in FIGS.
  • the sectional view of FIG. 5 shows that here the contact element 4 has a socket-like connection element in the form of a fork contact 12 instead of a connector plug.
  • the fork contact 12 interacts with a contact pin 16 which emanates from a terminal block 30 arranged under the mounting frame 1 and is guided through an opening 13 in the mounting frame 1 into the interior of the cavity 8 .
  • FIG. 7 shows the exploded view of the associated contact element 4.
  • the contact disk 17 on the contact body 10 is not circular here but rather elongated and has incisions, which forms a positive fit on the top of the cover 9, which is shaped to match. This makes it possible for the fork contact 12, which is connected to the contact disk 17, to be secured against twisting within the peripheral wall of the cover 9 to be arranged without fixing the fork contact 12 directly to the cover 9 itself.
  • FIG. 6 shows the fully assembled connection unit with three pressure contacts 2 on the mounting frame 1.
  • FIGS. 8 and 9 A third embodiment of the connection unit is shown in FIGS. 8 and 9.
  • a flat contact 11a is provided here as a connection plug, which protrudes laterally from the pressure contacts 2. As FIG. 9 shows, the flat contact 11a is formed in one piece with the contact disk 17 of the contact body 10.
  • the flat contact 11a can be contacted simply by connecting lines with cable lugs (not shown here). Since contact is not made inside the pressure contacts 2 here, the structure of the mounting frame 1 and the contact element 4 is simplified compared to the previously described embodiments.
  • Figure 8 shows an associated fully assembled connection unit with three pressure contacts 2 on the mounting frame 1.
  • FIGS. 10 and 11 A fourth embodiment of the connection unit is shown in FIGS. 10 and 11.
  • Flat contacts 11 b are again provided here as connection plugs, but here they are passed through the mounting frame 1 away from the pressure contacts 2 .
  • the flat contacts 11 b can either be pushed through recesses in the mounting frame 1 or cast into the mounting frame 1 .
  • the connection between the flat contacts 11b and the contact bodies 10 of the pressure contacts 2 takes place here in each case by means of a meandering structure 28 which can preferably be formed in one piece both with the flat contact 11b and with the contact body 10 .
  • the meandering structure 28 forms a multiply folded spring which elastically compensates movements of the contact element 4 relative to the flat contact 11b fixed to the mounting frame 1 .
