  • Contact blade parts having a plurality of contact blades for transmitting electrical currents or signals between two contact elements are known. Regularly, the contact blades are set up so elastically or flexibly that they are in the coupling state under a mechanical bias closely against at least one of the contact elements to ensure in this way a low contact resistance between the contact blade part and the contact element.
  • contact lamella parts in the manner of a lamellar cage 620 may be held in the interior of a contact socket 600 such that the contact lamellae of the contact lamella part project at least in sections into a receiving space for receiving a contact pin 610.

  • a contact blade part according to the invention is characterized in that the contact zone of a first contact blade is arranged offset in the longitudinal direction to the contact zone of a second contact blade.
  • the contact zone of a contact lamella can be understood as that section along the longitudinal axis of the contact lamella in which the contact lamella bears in a coupled state under elastic prestressing on at least one contact element such as a contact pin or on both contact elements such as a contact pin and a contact socket.

  • the contact zones of the two contact blades run side by side only over a predetermined section in the longitudinal direction.
  • the distance between the contact zone of the first contact blade (or the point of the contact zone, the furthest out of the lamellar plane) and the contact zone of the second contact blade (or that point of the contact zone, the furthest out of the lamellar plane) in the longitudinal direction more than 10%, preferably more than 20%, in particular 40% or more of the total length of the contact lamellae.
  • the invention is based on the knowledge that in conventional contact blade parts, the contact zones of all contact blades lie in the same cutting plane, in particular in each case in the middle of the respective contact blade. During the coupling process, therefore, the contact zones of all contact blades must be elastically deformed simultaneously, so that they are brought into close contact with the contact element. For this reason, a particularly high insertion force must be applied at a certain time, whereby the assembly process is difficult.
  • the contact lamella part according to the invention the contact zones of individual contact lamellae are offset from one another in the longitudinal direction, so that initially the first contact lamella and only then the second contact lamella are elastically deformed during the coupling process. As a result, the maximum insertion force to be applied can be reduced and in particular halved, and at the same time a good contact resistance can be provided.
  • the contact zones of two contact blades lie in two spaced apart in the longitudinal direction of the slats cutting planes, not only a good electrical contact, but also a reliable mechanical connection between the Contact lamellae part and the contact elements are provided, since along the longitudinal axis of the contact blades at least two spaced contact points is provided, against which the contact blade rests against the contact element. A Verkupplungs phenomenon between the two contact elements can be stabilized.
  • the contact blades are twisted at least in the region of their contact zones each about its own longitudinal axis and / or tilted.
  • a torsion about its own axis is understood to mean a torsion, a rotation and / or a tilting of the contact lamella in the course of its longitudinal extent.
  • torsion may be provided by a first cross-sectional area of the contact blade in a first cross-sectional plane perpendicular to the longitudinal axis substantially corresponding to a second cross-sectional area of the contact blade in a second intersecting sectional plane but rotated by a predetermined angle with respect to the first cross-sectional area or tilted.
  • the contact blade has the form of a web with a predetermined web width in a width direction, wherein the web is increasingly tilted in the course of the longitudinal axis of the contact blade with respect to the original width direction.
  • the width direction of the web in a non-tilted land portion and the longitudinal axis of the land define the fin plane, the land being progressively tilted along its length relative to the fin plane, for example, up to a tilt angle greater than 5 ° and less than 90 ° °, in particular more than 15 ° and less than 45 °.

  • the contact blade does not have in its longitudinal direction as a whole a curved or curved course, but a straight, but twisted around its own axis course.
  • a curve of the contact blade which is simultaneously twisted about its own axis and which is curved with respect to the longitudinal axis is conceivable.
  • a curved contact blade also has the longitudinal direction L of the contact blade a curved course, which follows the curved longitudinal extent of the contact blade.
  • Contact blades with respect to the longitudinal axis curved or curved course have widely spaced contact points for contacting the two contact elements. So contacted the in Fig. 6 shown contact blade part in the coupling state, the contact pin in the middle of the contact blades and the contact socket at the two ends of the contact blade part in the longitudinal direction. In this case, the current-carrying path runs from the middle of the contact blades in the longitudinal direction of the contact blades to the two ends of the contact blade part. This can lead to a comparatively high contact resistance through the contact lamella part and thus possibly associated heating and losses.
  • twisted or tilted contact lamellae about their own longitudinal axis are suitable in a small space, namely in the region of the contact zone, both for contacting the first contact element and for contacting the second contact element.
  • a first side edge of the tilted contact zone is disposed on the opposite side of the fin plane as the second side edge of the contact zone, so that the current guide path can extend substantially in a transverse direction through the contact blades.
  • the contact blade in the contact zone is tilted such that the current-carrying path extends in a width direction from the first side edge of the contact zone to the second side edge of the contact zone, the first side edge being the first Contact element and the second side edge in substantially the same sectional plane electrically contacts the second contact element.
  • the first contact lamella is preferably the contact lamella adjacent to the second contact lamella.
  • the first contact blade contacts at least one of the contact elements in a different cutting plane than the immediately adjacent second contact blade, which can run parallel to the first contact blade.

  • the distance between the two contact planes in the longitudinal direction may be more than 5 mm and less than 5 cm, in particular more than 1 cm and less than 3 cm, which may correspond to more than 40% of the total length of the contact blades.
  • the alternating arrangement of the contact zones of adjacent contact blades improves on the one hand a coupling stability and on the other hand minimizes the insertion force required for a coupling, since this is to be applied at two spaced plug positions each with approximately half the reduced total amount.
  • the contact zones of the contact blades are not simply arranged alternately (XYXYXY etc.) in different contact planes, but in a different sequence.
  • the contact zones are provided in a multiply alternating (for example XXYYXXYY etc.) or a non-alternating sequence (for example XYYXXX etc.).

  • the two connecting rods of two adjacent contact blades are offset from one another in the longitudinal direction in such a way that no cutting plane running perpendicular to the longitudinal direction intersects both connecting rods. In this way it is prevented that between two adjacent contact blades at least partially a wide slot is formed, which may have a negative effect in terms of a good shielding effect.
  • the torsion bar preferably has a substantially constant Width over more than half, in particular over more than 75% of the total length of the contact blade extends.

Only then the contact zones 231 of the second contact blades 221, which are also tilted with respect to the circumferential direction U, are elastically deformed, which are offset in the longitudinal direction L, which corresponds to the plugging direction S, from the contact zones 230 of the first contact blades 220 by a distance A1. This facilitates the coupling process.
  • Fig. 5A shows a connector 500 according to the invention with a received in a contact socket 510 contact blade portion 200.
  • the contact blade portion 200 may radially outwardly projecting projections such as lugs 512, by means of which the contact blade portion 200 can be fixed in the contact socket 510.
  • Fig. 5B shows the in Fig. 5A shown connector 500 in a perspective view.
  • the contact socket 510 is substantially hollow cylindrical in shape and serves to insert a complementarily shaped contact pin 520 in the plugging direction S.
  • the contact lamella part 200 has a plurality of contact lamellae 220, 221 arranged side by side in a circumferential direction U and extending in the plugging direction S, whose contact zones are tilted about the respective lamellar axis in such a way that their first side edges 240 for electrically contacting an inner wall of the contact lamella part Contact socket 510 are provided and their second side edges 241 protrude into a circumvented by the contact blade part inner volume 550 for receiving the contact pin 520.
  • the contact zones of adjacent contact blades are each offset in the direction of insertion. Furthermore, the width profiles of adjacent contact blades are each provided essentially in the opposite direction. In this way, on the one hand, a simple coupling process can be made possible. On the other hand, a small contact resistance can be made possible due to the short current paths, so that the contact blade part according to the invention is suitable for the transmission of high current. Furthermore, a good shielding effect can be provided, so that the contact lamella part according to the invention can be used for transmitting signal or for shielding one or more signal conductors.
  • a different sequence can also be provided. If those contact lamellae whose contact zones are in the first contact plane E1 are denoted by X, and those contact lamellae whose contact zones are in the second contact plane E2 are denoted by Y, then in the direction of extent the carrier strip U can instead of simply be alternating sequence XYXYXY shown in the figures, a double alternating sequence XXYYXXYY or a multiple alternating sequence XXXYYYXXXYYYYY or the like. be provided.
  • an asymmetrically alternating sequence may be XYYXYY, XXYXXY, XYYYXYYY, XXXYXXY or the like. be provided.
  • the sequence of the contact blades X and the contact blades Y is not alternating, for example. XYYXXYYY or the like.
  • a third group of contact blades Z provided, the contact zones in the longitudinal direction L are provided both to the contact zones of the first contact blades X and to the contact zones Y of the second contact blades.
