Definitions

  • the invention relates to a contact pin for plug connections, which is provided with impressions on its periphery and can be inserted into a receiving opening of a plastic body and fastened therein by clamping, the impressions being pressed into the inner wall of the receiving opening.
  • Such a contact pin is known from DE-OS 25 23 448.
  • This contact pin is formed with a holding shaft with a square cross section, into which circumferential transverse ribs, which are inclined at an angle to the longitudinal axis of the pin and flattened at the highest points, are embossed.
  • the invention has for its object to achieve a sufficient tightness with a contact pin of the type mentioned in a reproducible manufacturing process and to ensure the highest possible holding forces.
  • a contact pin of the type mentioned in accordance with the invention in that the impressions are provided at two points located one behind the other in the longitudinal direction of the contact pin and are each attached in pairs at two opposite points on the circumference of the contact pin and as beyond the circumference of the contact pin protruding pairs of lugs are executed, and that these pairs of lugs each have a rising opposite to the direction of insertion of the contact pin contour.
  • a contact pin of this type is stamped at two adjacent points in the longitudinal direction with two sides stamped on its circumference Nose pairs, that is to say with a total of four pairs of noses, which are attached in a simple manner in a reproducible manufacturing process by means of stamping dies, which print the material of the contact pin beyond its original circumference to the outside.
  • the pairs of lugs have a contour which rises in the opposite direction to the direction in which the contact pin is inserted, with nose flanks which are inclined at an angle to the longitudinal axis of the contact pin and a steep rear flank.
  • the rear nose pairs in the insertion direction have a greater height than the front nose pairs. This measure ensures the secure fit of one Contact pin in the receiving opening of a plastic part additionally improved.
  • This advantage can also be achieved in a second exemplary embodiment of a contact pin according to the invention in that the pairs of noses at one point of the contact pin are offset by 90 ° relative to the nose pairs at the other point of the contact pin on the circumference of the contact pin.
  • the contact pin has, for example, a square cross-sectional shape with an edge length of, for example, 0.6 mm and is provided with embossments on its circumference at two points lying one behind the other in the longitudinal direction of the contact pin.
  • embossments on its circumference at two points lying one behind the other in the longitudinal direction of the contact pin.
  • these are each attached in pairs at two mutually opposite locations on the circumference of the contact pin and are designed as pairs of noses projecting beyond the circumference of the contact pin, these pairs of noses each having a contour that increases in the opposite direction to the direction in which the contact pin is inserted.
  • 1 to 7 accordingly has two pairs of lugs 3 and 3 'at a first location at two mutually opposite locations and also at two at a closely adjacent second location opposite points - based on the circumference of the contact pin - lying in the same angular position - each two further pairs of noses 4 or 4 ', the two noses of a pair of noses 3, 3', 4 or 4 '- as is particularly clear from the enlarged view 4 can be seen - are impressed into the contact pin from above and below.
  • the pairs of lugs have a contour which rises in the opposite direction to the direction in which the contact pin 1 is inserted, so that they protrude beyond the original circumference of the contact pin with nose flanks 5 inclined obliquely to the longitudinal axis of the contact pin and a steep retaining flank 6 transverse to the longitudinal axis of the contact pin.
  • the rear lug pairs 4,4 'of the contact pin 1 have a greater height than the front lug pairs 3,3', so that the contact pin 1 in section BB has a somewhat larger cross section than section AA .
  • a contact pin 1 is inserted into a receiving opening of a plastic part 2, for example into a pin strip, in a direction of insertion indicated by an arrow 7. In its end position shown in FIG. 7, the contact pin 1 is then securely anchored in the plastic part 2 in the event of forces occurring in the direction of an arrow 8 (direction of holding force) due to the barb-like pairs of lugs.
  • the second embodiment of a contact pin 1 a shown in FIGS. 8 to 14 differs from the embodiment shown in FIGS. 1 to 7 only in the angular position of the pairs of noses 3, 3 'and 4, 4' in relation to the circumference of the contact pin. .
  • the 7 rear pairs of noses 4,4 'in the direction of insertion are offset by 90 ° with respect to the front pairs of noses 3,3', the front and rear pairs of noses 3,3 'and 4,4' being able to have the same height. Otherwise it is Contour and the arrangement of the pairs of noses 3,3 'and 4,4' identical to the embodiment according to FIGS. 1 to 7.
