Definitions

  • the invention relates to a contact element for electrical plug connections according to the preamble of claim 1.
  • Such contact members designed with a pin contact are in general - of a latching in a connector housing by means of a spring in certain areas of application apart from that - otherwise floating in the connector housing stored. Therefore, the pin contact area is guided of the contact element for precise alignment with a socket contact required. Because, on the one hand, one that may be used Overspring and on the other hand the guide length a certain Length of the pin contact, there is a risk damage to the pin contact, for example by bending and thus bending from the direction of insertion, in particular in rough workshop and assembly use. A certain one Protection against such damage is at Use contact organs z. B. achieved by that a wire-shaped contact pin with a cross section of for example, 0.63 x 0.63 mm on one by punching it out Band material made and bent contact member welded becomes,
  • a contact organ of the type mentioned is through EP 0378 466 B1 known. This by cutting and Wrinkles from a metal plate, which are two stripes different Has thickness, have produced contact member the contact pin and the part of the U-shaped body has a thickness that is larger than that the rest of the contact organ. That way the stability in the area of the connection to the U-shaped Body to be improved.
  • a knife contact element is known from US-A-5 207 603, in the one between a contact knife and a line connection element located in between Turn formed section that follows the Bend point at the intermediate area again in the reverse Direction is bent to form a contact knife this contact knife in turn by folding it up is formed by two contact knife plates. So the tiles don't move against each other, are on everyone Platelet two holding tabs formed by a respective Recess in the edge of the two plates around each other tiles are curved. Critical with this knife contact is the area of the bend at which the contact knife in passes over the section parallel to the direction of insertion. To this Reinforcing sections are one in the sheet Platelet two pronounced reinforcing ribs, which in Run the longitudinal direction of the contact knife over the bending point.
  • the invention has for its object in a contact member the type mentioned in a simple way an improved Securing the contact pin against damage, especially against bending from the direction of insertion.
  • the contact pin With such a contact element, the contact pin is on the place where it is most at risk of bending is, namely in the area of its at the U-shaped intermediate area connected base, by positive locking with connecting elements of the intermediate area secured.
  • This backup is due to its form-fitting character in a simple manner without additional effort at the same time the manufacture of the contact element as a stamped and bent part, since the connection elements provided for this Manufacturing process with punched and bent can.
  • this stabilization is not directly at the connection point of the contact pin at the intermediate area, but something of it offset towards the free end of the contact pin.
  • the connecting elements are up to the position of the positive Connection to a certain lever arm, which advantageously supports the contact pin laterally and further improved its rigidity.
  • connection z. B. can be brought about by the fact that the connecting elements grasp the contact pin like a claw.
  • the Formation of a guide slot for the contact pin possible the guide slot of two on the side of the contact pin adjacent and by embossing, clawing, die cutting and / or turning connected to the contact pin in a form-fitting manner Extensions can be formed. After all it is also possible to extend the intermediate area from the To engage in the contact pin from the side. advantageous Refinements of such connection options are specified in the subclaims.
  • the contact element 1 shown in the drawing is in all its embodiments according to Figures 1 to 7 as a whole made from a stamped and bent part and has for all designs a uniform, basic structure. Accordingly, the contact element 1 has a U-shaped cross section Intermediate area 2 with two side walls 3, 4 and one this connecting base wall 5, further a z. B. as Crimp element formed line connection element 6 with subsequent perforated plate 7 at one end of the contact member and a contact pin protruding from the intermediate area 2 8 at the other end of the contact element.
  • the contact pin is in any case thicker than the other areas of the Contact organ, the material thickness z. B. continuously 0.25 mm is. In contrast, the z. B.
  • Contact pin 8 has a thickness of, for example, about 0.6 x 0.6 mm. In all embodiments, that is from the intermediate area 2 contact pin 8 projecting forward on the contact side Area of its base connected to the intermediate area, so that it prevents bending from the direction of insertion is secured.
  • the extension 9 the side wall 3 carries the contact pin 8 and is in the area the transition into the contact pin with a side flap-like Approach 11 provided.
  • the extension 10 of the side wall 4 is slightly longer than the opposite extension 9 and lies against the side of the contact pin 8.
  • the height the side wall 10 corresponds approximately to that in this area Contact pin thickness.
  • both side walls are 3, 4 of the U-shaped intermediate area 2 on the contact side the U-profile also with strip-like extensions 9, 10 formed, which here again on each other run.
  • the base wall 5 of the intermediate area 2 beyond the U-profile with a strip-like Extension 15 provided, which extends up to the connection of the contact pin in turn carried by the extension 9 8 extends and with a lateral, lobe-like Approach 16 is formed, which is transverse to the contact pin is directed.
  • This approach 16 is angled by means of bends, that it includes the extension 10 like a claw and presses against the contact pin 8.
  • Figures 3 to 6 show other embodiments of a positive connection of connecting elements of the intermediate area 2 of a contact element 1b to 1e with the contact pin 8.
  • the side wall 3 of the intermediate area 2 in turn a contact pin 8 carrying, over the U-profile going beyond extension 9.
  • the base wall 5 of the intermediate area 2 again with one over the U-profile extending extension 15 is formed.
  • This Extension is about from the point of connection of the contact pin to the extension 9 of the side wall 3 to thicker than the base wall, preferably as thick as the contact pin itself. Then connect to yourself via the connection point of the contact pin on the extension 9 extending thicker area 20 is the extension 15 with approaches in Formed by two guide legs 21b, 22b and L-shaped angled.
  • Figures 4 to 6 show a contact element 1c to 1e with a Guide slot for the contact pin 8 and one through Claw produced positive connection of the connecting elements with the contact pin.
  • the contact element 1c according to FIG. 4 is again the side wall 3 with a contact pin 8 carrying, over the U-profile outgoing extension 9 formed, where the base wall 5 in the longitudinal direction of the contact member with a Extension 15 also extends beyond the U-profile.
