Definitions

  • the invention relates to a contact pin-contact spring socket assembly, in which the contact pin has two approximately parallel, a slot formed by punching oblong, mutually resilient, serving for pressing into an opening in a circuit board, one of which serves to limit the insertion path shoulder one Carrier part is assigned, and in which the contact spring bushing comprises a plurality of contact springs, which extend approximately from the region of the shoulder of the carrier part at a distance from the socket axis to the region of the front pin insertion opening and have the smallest distance from the socket axis in their central region .
  • the contact pin is as with the carrier part that serves to limit the insertion path Has shoulder, one-piece component formed. This is first produced as a turned part, which comprises the shoulder and a contact pin section protruding therefrom, from which the elongated hole is punched out after the material that is superfluous on both sides has been milled and thus converted into a flat shape in a subsequent punching process.
  • contact pin contact spring socket assemblies can be produced in a much simpler way than before in perfect quality if the contact pin is designed according to the invention as a stamped part which is independent of the carrier part which has the shoulder serving to limit the insertion path and can be connected to the shoulder via a clamping connection element.
  • the carrier part is expediently provided with a clamping bore which is open on the side facing away from the contact spring bushing and into which the contact pin with its rear pin end can be inserted to produce a clamp connection.
  • the rear pin end of the contact pin has a rectangular, preferably square cross-section and the distance between the diametrically opposite pin edges is matched to the diameter of the clamping bore.
  • the pin end has two approximately parallel, resilient, resilient locking legs which can be inserted into the locking hole and which are analogous to the contact pin and delimit a punched slot.
  • the flat-shaped contact pin 3 facing away from the plug insertion end is provided with two approximately parallel legs 5 that are resilient to one another and that delimit an elongated hole 4 formed by punching out. These legs 5 end in a pin end 6, which is provided in a central clamping bore 7 in a carrier part 8 with a shoulder 8 of the contact spring bushing 2 serving to limit the insertion path.
  • the illustrated Embodiment the contact springs 9 inserted into the socket interior with their rear end on a cylindrical ring extension 10 which protrudes from the shoulder and has an annular groove 11 on its foot.
  • the flanged edge of the socket body 12 of the contact spring socket 2 which is designed in the form of a thin-walled deformable sleeve, engages in this annular groove 11. The edge presses under contact with the shoulder on the shoulder between the contact springs 9 located between it and the ring shoulder 10.
  • annular body 14 lies against the flange, the inside diameter of which is selected to be somewhat smaller than the pin insertion opening 13 provided in the socket body 12.
  • the contact springs 9 distributed on the inner circumference, which are fixed in the region of the shoulder, are freely movable with their free ends in an annular gap 15 delimited between the socket body 12 and the annular body 14.
  • the radially inward curvature of the contact springs 9 illustrated in FIG. 5 is achieved in that the socket body 12 from the outside at two points axially offset with respect to the ring body 14 or the ring extension 10 each with a radially inward distance projecting annular bead 16 or 17 is provided, which abuts the contact springs 9 and elastically deforms them radially inwards.
  • the socket body 12 is provided in the region of each annular bead 16 or 17 with an inner diameter which is smaller than the outer diameter of the annular body 14 supporting the free ends of the contact springs 6, increased by twice the diameter of the contact springs 9.
  • FIG. 5 In the case of the contact socket / contact pin assembly 1, which is shown in simplified form in FIG. 1, the embodiment according to FIG. 5 is illustrated in more detail an additional radial indentation 18 is provided in order to press the contact springs (not shown) inside the contact spring bushing 2 firmly against the ring extension 10, which is also not shown.
  • Fig. 2 illustrates the simplest form of the formation of the rear pin end 6 of the contact pin 3.
  • the pin end 6 has a rectangular, preferably square cross section, and the distance between the diametrically opposite pin edges is matched to the diameter of the clamping bore 7. Due to the slight oversizing of the pin edge diagonal distance, the pin edges engage when connecting the contact pin 3 via the pin end 6 into the wall of the clamping bore 7 of the contact spring bushing 2. This ensures a firm hold and also a perfect contact.
  • FIG. 3 shows an improved cross-sectional shape of the pin end 6.
  • two opposite sides of the pin end 6 are provided with an approximately axially parallel bulge 19 directed towards the pin axis.
  • the outer edge regions of the pin end 6 are each elastically deformable toward the axis of curvature of the curvature 19 during the insertion process.
  • the pin end 6 is provided, analogously to the actual contact pin 3, with a punched-out portion, by means of which two clamping limbs 21 delimiting a clamping elongated hole 20 are formed, which spring towards one another when inserted into the clamping bore 7.
