Definitions

  • the invention relates to a double flat spring contact with two opposing spring legs, which are connected to a contact box having a parting line, on which a connection zone is arranged, and to a device for preventing expansion of the contact box.
  • Double flat spring contacts have long been known for their basic structure. These are small to very small stamped and bent parts made of metal, with wall thicknesses of just a few tenths of a millimeter.
  • the parting line opens, if necessary, and the two affected contact legs are slightly inclined.
  • the present invention is therefore based on the object of providing a double flat spring contact of the generic type which, with the least possible design effort, reliably prevents the contact box from widening while ensuring the required suspension values in the area of the spring legs.
  • the solution according to the invention consists in that the device for preventing the expansion of the contact box is formed by a tab projecting on a contact box wall on the parting line with an undercut geometry and a corresponding recess formed in the adjacent contact box wall for receiving the tab, wherein the tab is arranged at least in the expansion direction of the contact box without play in the recess, on which the tab carrying the wall of the contact box in the region of the joint is formed a stop shoulder.
  • the double flat spring contact according to the invention is thus distinguished by the lack of the disadvantages mentioned at the outset, which are associated with an expansion of the contact box, with a conceivably simple structural design. Since only the two contact spring legs now spring, contacting the above-mentioned pins and knives leads to line contacting with correspondingly high service life cycles. The now even stress distribution in the two spring leg cross sections results in significantly lower peak stresses. This results in a significantly increased security against plastic deformation. Furthermore, the relaxation behavior at higher temperatures is considerably less pronounced due to the lower voltage in the tip.
  • the double flat spring contact shown in FIG. 1 is a small sheet metal part, which is produced in large quantities as a stamped and bent part from a sheet metal with a wall thickness of a few tenths of a millimeter.
  • a typical design of the spring characteristic is, for example, the design for a pin to be inserted of 1 x 1 mm and a flat knife from 0.8 x 1.6 mm to 08 x 2.4 mm with a maximum current carrying capacity of the contact system of 16 A.
  • the order of magnitude should be noted that such contacts are designed in their external dimensions, for example, for a grid dimension or a row spacing of 5.08 to 5.0 mm.
  • the double flat spring contact in question essentially consists of a contact box 1, which is formed by a right-angled bend in accordance with the wall regions formed in the blank, the two opposite spring legs 2 and 3 being molded onto two opposite walls.
  • a connection zone is provided, which in the exemplary embodiment according to FIG. 1 is designed as a normal crimp connection 4a.
  • the parting line 5 of the contact box 1 is located in one of the box corners.
  • one of the contact box walls involved in the formation of the joint 5 in the exemplary embodiment according to FIG. 1, the upper wall 1a, a projecting tab 6 with an undercutting geometry, in the exemplary embodiment shown a substantially T-shaped tab, formed in a projecting manner and in the other wall 1b of the contact box 1 adjoining the joint 5, a recess 7 corresponding to the tab 6 and receiving it is formed.
  • the tab 6 is embossed on all sides in the recess 7 without play, as a result of which it finds a spring-free, rigid and in particular also very reliable hold in order to prevent it from picking up when making contact expanding forces occurring with regard to the very small wall thicknesses in question here come out of the recess 7.
  • an abutment shoulder 8 is formed on the contact box 1 in the region of the joint 5, which serves as a stop during the formation of the contact and advantageously limits the bending process.
  • a stop leg 10 bent downwards at right angles is formed on its end edge opposite the spring leg 2.
  • the stop leg 10 can on the other hand be used as a wire stop when connecting a wire in the connection zone 4a.
  • connection zone 4b arranged on the contact box is not designed here as a crimp connection, but rather as an insulation displacement connection.
  • two insulation displacement zones 11, 12 are provided.
  • the actual insulation displacement gap 13 is punched in the cut and bent up by 90 ° in a station in the punching tool, as a result of which a considerable accuracy of the gap dimension can be achieved during cutting and the dimensional tolerance can be kept very small.
  • the connection zone 4b is essentially box-shaped and is formed by the two U-shaped bent-up side walls 14, 15, which are stiffened and stabilized in the floor area by a connecting web 16.
  • the insulation displacement gap 13, as illustrated in FIG. 3, extends over the region of the lower 90 ° bend. This ensures that a resilient leg length, namely the leg length extending over the 90 ° bend in the bottom region, remains even when small individual wires are pressed in up to the base of the connection box. Otherwise, the deflection of the two cutting legs 17, 18 could go to zero for a given contact force or the contact force could become extremely large for a given deflection of the cutting legs 17, 18, which could lead to cracks due to excessive mechanical stress in the area of the cutting gap base. and there is a risk of breakage, or would cut through a bundle of cracks or part of the individual wires.
  • the inner spacing between the U-shaped upturned side walls 14, 15 can expediently be varied in the punching tool, since this can support the spring behavior of the two cutting legs 17, 18.
  • An additional force can be generated by the side walls, which can be applied to the cutting legs in order to increase the contact force in the insulation displacement gap or to reduce the bending load in the cutting legs while the contact force remains the same.
  • an insulation crimping zone 19 is located next to the insulation displacement zone 11, 12. The crimping takes place when the individual wires are pressed into the insulation displacement connection zone. The insulation crimping keeps tensile loads away from the cutting zones.
