Definitions

  • the invention relates to a method of manufacturing an electrical contact of the push-button type, intended to fit in an electrical connector, and to an electrical contact.
  • the head is slidingly mounted relative to the connection element along a sliding direction and brought back to a rest position by a spring.
  • the other electrical contact of the complementary connector is usually a nearly flat or slightly curved surface, sufficiently large to allow a large mismatch between the axes of the two complementary connectors.
  • an advantage of the push-button system over more conventional mal/female contacts systems is that it allows large tolerances in the positioning of the two complementary connectors, in all three directions, while providing a good contact pressure for a low electrical resistance.
  • the contact is manufactured by cutting, out of a conductive sheet, a plane contact pattern comprising a connection element part, a head part and a straight plane strip.
  • the spring is formed from the plane strip by multiple cambering, which leads to a corrugated strip.
  • the head and connection elements are then formed from the head and connection element parts by rolling up the contact pattern along the sliding direction.
  • the invention provides a method of manufacturing an electrical contact as set forth in claim 1.
  • Other features of the method are set forth in dependant claims 2 to 10.
  • the invention further provides an electrical contact as set forth in claim 11. Other features of the contact are set forth in dependant claims 12 to 22.
  • FIGS. 1A, 1 B and 1C are perspective views of an electrical contact according to a first embodiement of the invention
  • FIG. 2 is a perspective view of an electrical contact according to a second embodiment of the invention.
  • - Figure 3 is a plan view of a contact pattern for manufacturing the contact of figures 1A, 1B and 1C; and - Figure 4 is a block diagram of a method of manufacturing the contact of figures 1A, 1B and 1C, using the contact pattern of figure 3.
  • the head also comprises a contact tab 24, extending from the wall of the cylinder body 20 and covering an end opening of the cylinder body 20.
  • the contact tab 24 is intended to come into contact with another contact of another connector.
  • the spring 16 is a winding strip 28 comprising a plurality of side-by- side rungs 28A, having the shape of split rectangular rings with a size corresponding to the size of the rectangular cylinder body 20.
  • the rungs 28A are parallel to each other and perpendicular to the sliding direction X. They are linked one to another by a winding 28B located alternatively at each end of the rungs 28A. In other words, one end of a rung 28A is linked by a winding 28B to a previous rung 28A, whereas the other end is linked by another winding 28B to a next rung 28A.
  • the winding strip 28 is rolled up around the sliding direction X and the windings 28B located at one end of the rungs 28A are near the windings located at the other end of the rungs 28A.
  • the winding strip follows longitudinally a line which winds on a geometrical surface.
  • the geometrical surface is the rectangular cylinder defined by the body 20. That is to say that the line winds on the geometrical surface in prolongation of the body 20.
  • the smallest dimension of the winding strip is perpendicular to the geometrical surface, so that the thickness of the strip is perpendicular to the sliding direction X, and folds upon itself to form the windings.
  • the spring 16 provides electrical connectivity between the head 14 and the connecting element 12. Because the spring is a narrow strip, its resistivity is high, so as to provide electrical connectivity with low resistivity between the head 14 and the connection element 12, the tabs 26 of the head 14 come into contact with this shell 18 while the head 14 slides relative to the shell 18. This contact with the shell 18 also helps the guiding of the head 14 along the slinding direction X.
  • the contact 10 comprises a slot 36, provided in the head 14, and intended to cooperate with a finger 38 extending form the shell 18.
  • the slot 36 is rectangular with its length extending along the X direction.
  • the finger 38 extends toward the inside of the shell, i.e. toward the head, perpendicularly to the X direction.
  • the finger 38 penetrates in the slot and cooperates with the edge of the slot 36 in order to keep the spring 16 partially compressed while not in contact with the other complementary connector.
  • the pre-compression of the spring enables the contact to have a short length since the strength of the spring is high for a short stroke of the head 14 from its rest position to its compressed position.
  • the contact tab 24 come into contact with the other connector. Further to the contact, the head 14 is pushed back by the other connector. The spring 16 is compressed and produces in return a restoring force and thus a good contact pressure. The stroke of the spring; i.e. its possible displacement, must be sufficient to achieve a desired restoring force and counterbalance the tolerance between the two connectors.
  • the contact is very similar to the one of figure 1A, 1B and 1C. It differs by the fact that the head 14, the spring 16 and the shell 18 have a circular shape around the slinding direction X.
  • the method first comprises a step 100 of cutting out of a conductive sheet, such as a metal sheet, a plane contact pattern 40 comprising a connection element part 42, a head part 44, a spring part 46 and a shell part 48.
  • a conductive sheet such as a metal sheet
  • a plane contact pattern 40 comprising a connection element part 42, a head part 44, a spring part 46 and a shell part 48.
  • the conductive sheet is cut out along its thickness, i.e. perpendicularly to its largest surface.
  • the head part 44 comprises a rectangular plate 50 in which the tabs 26 are cut of, and from which the contact tab 24 extends in a coplanar way. Moreover, the slot 36 is cut out between the tabs 26.
  • the spring part 46 comprises a plane winding strip pattern 51 , whose thickness corresponds to the thickness of the sheet.
  • the winding strip pattern 51 comprises rectilinear side-by-side rung patterns 51A, parallel to each other and linked two by two by windings 51 B placed alternatively at each end of the rung patterns 51 A.
  • the windings 51 B are cut of from the sheet with dimensions such that they are elastically deformable. In other words, the winding strip 51 extends longitudinally along a line which winds on the largest surface of the sheet, i.e. a face of the sheet in contradistinction to its thickness.
  • the shell part 48 is made of a rectangular plate 52 comprising on one side a locking tab 54. A corresponding locking gap 56 is cut out on the opposite side, for receiving the locking tab 54.
  • the finger 38 is cut out from the rectangular plate. The extremity of the finger connected to the rest of the shell part 48 is located below, along the X direction, the position of the slot 36.
  • the manufacturing method then comprises forming steps 200, 300 and
  • the electrical contact 10 is formed from the contact pattern 40.
  • the spring part 46 and the head part 42 are rolled up around the sliding direction X so as to form the rectangular cross section cylinder body 20 of the head 14 and the rectangular cross section surface on which lies the spring 16.
  • the locking tab 54 and the locking gap 56 are engaged so as to prevent the cylinder 20 of the head 14 from unfolding.
  • the contact tab 24 is fold down over the aperture end of the cylinder body 20 of the head 14, and the tabs 26 are spread away from the cylinder body 20. Also during this step, the finger is folded perpendicularly to the X direction.
  • connection part 42 and shell part 48 are rolled up around the sliding direction X. More precisely, the shell part 48 is wrapped up around the spring 16 and at least in part the head 14 at its rest position. During this step, the spring 10 is compressed such that the finger 38 is able to penetrate in the slot 36.
