Definitions

  • the invention relates to a spring arm contact equipped with an over-spring, in particular a flat spring arm contact in miniature design.
  • a flat spring arm contact in particular, the flat spring arm contact, as abbreviated as usual, is called flat spring contact.
  • Such contacts are e.g. only 17.5 mm long and 2 mm flat. It is therefore difficult to set an over-spring on such a contact.
  • Several clamping and bearing elements or locking devices are to be provided in order to apply the spring to e.g. to position the flat spring contact so that it is held captive and immovable and ensures the required increase in the spring force of the flat spring contact.
  • the large number of bearing and locking elements requires a lot of effort during assembly and increases the cost of producing the flat spring contact with a spring.
  • the object of the invention is to provide a spring contact, in particular flat spring contact, with an external spring, which requires extremely little and easy-to-form bearing or locking elements, which are accomplished with simple means and are easy to deform during assembly.
  • the flat spring contact 1a made of a stamped sheet metal part consists of the crimp area 1, the spring arm base 2 and the contact area 3.
  • the crimp area 1 is designed as usual and therefore does not need to be explained in more detail.
  • a box-shaped spring arm base 2 is connected to the crimp area 1 via an approximately — in cross section — U- to V-shaped connecting web 4 with a base 5, two side walls 6 and 7 and a top wall 8. At the front edge 9 and 10 respectively Ceiling wall 8 and the floor 5 are each connected to two forwardly extending, longitudinally divided spring arms 11, 12 and 13, 14, which converge at an angle, touch each other in the contact line 15 and diverge from there to form a funnel 16.
  • the front edge 17 is arranged somewhat recessed compared to the front edges of the bottom 5 of the side wall 7 and the top wall 8 (FIG. 4). The purpose of this arrangement is explained below.
  • a hole 18, the spatial shape of which is essential is preferably made in the center of the side wall 6.
  • the hole 18 is hexagonal and has two longitudinal edges 19 of equal length and four oblique edges 20 of equal length, the longitudinal edges 19 being longer than the oblique edges 20.
  • the longitudinal edges 19 preferably extend in the longitudinal direction of the spring arm base 2 parallel to the longitudinal axis 21 of the spring arm base 2.
  • the outer spring 22 made of a stamped sheet metal sits, as known per se, form-fitting on the flat spring contact 1a.
  • the sheet of the outer spring 22 is thinner than the sheet of the flat spring contact 1a, but the material from which the outer spring 22 is made has a stronger spring force than the material of the flat spring contact 1a.
  • the outer spring 22 also has a box-shaped spring arm base 23 with two side walls 24, 25, a bottom 26 and a top wall 27, spring arms 34 which extend forward and are connected to the bottom 26 and the top wall 27 and which extend from the outside onto the spring arms 11 , 12 or 13, 14 of the flat spring contact 1a.
  • detent spring tongues 28 are introduced in a manner known per se by means of a U-shaped free cut, which protrude towards the rear and the outside.
  • the board of the outer spring 22 (not shown) is cut so that the abutting edges 29 of its spring arm base 23 are arranged in the longitudinal center of the side wall 6 of the spring arm base 2 of the flat spring contact 1a. Congruent with the hole 18 in the side wall 6, starting from each abutting edge 29, dovetail-shaped tabs 30 are cut opposite one another into the side wall parts 25a, 25b, each with two side edges 31 and one longitudinal edge 32.
  • the tabs 30 are in the interior of the spring arm base 2 bent, the spatial shape of the rag is adjusted to the spatial shape of the hole 18 that the side can grab 31 of tab 30 behind the corresponding beveled edges 20 of hole 18 and get caught there.
  • a very effective locking or anchoring of the outer spring 22 in the spring arm base 2 of the flat spring contact 1a has thus been achieved with simple means.
  • the invention has been described above by way of example using a box-shaped flat spring contact.
  • the locking or anchoring according to the invention can be implemented just as effectively with a different spatial shape of the contact or the spring arm base, for example with a round spring arm base. It also does not matter where the hole 18 is made; it can be provided in the floor or in the ceiling wall instead of in a side wall. However, it should be placed where the abutting edges of the spring arm base of the contact are not located.
  • 5 and 6 show as a preferred example a connection of the spring arms 11, 12 and 13, 14 to the side walls 6, 7, the abutting edges of the spring arm base 2 being in the ceiling wall 8 and the hole 18 being made in the bottom 5 is.
  • the outer spring 22 is adapted so that the abutting edge 29 of the outer spring 22 lies in the opposite wall to the wall of the spring arm base 2, in which the abutting edges of the spring arm base 2 are arranged.
  • even the top wall 8 of the spring arm base 2 may be missing and the spring arm base 2 may be U-shaped.
  • the detent spring arms 28 are expediently arranged on the side walls 24, 25 in this version. This can be done by the free cut recessed edge 17 and the locking tabs 33 are missing (FIGS. 5 to 7).
  • the special three-dimensional shape of the hole 18 in the form of a hexagon with the beveled edges 20 and the special three-dimensional shape of the dovetail-shaped tabs 30 with the side edges 31 not only form an immovable mounting of the outer spring 22 on the spring arm base 2, but also a hooking of the spring 22 in this way that the abutting edges 29 of the outer spring 22 cannot open, which means that the spring force of the spring arms 34 of the excess spring 22 remains unchanged when spreading or cannot be impaired as a result of spreading of the abutting edges 29.
