Definitions

  • the invention relates to a crimp barrel prepared for crimping in order to crimp an electrical conductor of a predetermined diameter.
  • the crimp barrel comprises a crimp base that is disposed between two crimp wings and that is provided with a support region having a first curvature for said electrical conductor, wherein a respective region with a second curvature is disposed on both sides of said support region, wherein a curvature diameter of said second curvature is smaller than a curvature diameter of said first curvature and wherein said crimp base is less rigid, in particular less flexural rigid than said crimp wings.
  • Crimp barrels of the aforementioned kind are crimped onto a wire braid of the electrical conductor, for example, as a support barrel.
  • the size or geometry, respectively, of the crimp barrel is matched to the diameter of the electrical conductor.
  • a crimp barrel provided for this diameter can therefore be used to crimp the electrical conductor.
  • the crimp barrel can there serve as a support for an electrical contact that can be crimped around the crimp barrel to terminate the electrical conductor. It is important that individual strands or shielding wires of the electrical conductor do not protrude radially from the crimp barrel or get caught in a crimp seam. This problem leads to discard in the production of a crimped conductor.
  • a special crimping tool can be used which is provided, for example, with spring assemblies for pressing the electrical conductor onto a support region of the crimp barrel during the crimping process.
  • spring assemblies for pressing the electrical conductor onto a support region of the crimp barrel during the crimping process.
  • crimping tools are very specific and not always available at the place of use.
  • a support barrel for an electrical lead, in particular for a coaxial cable is shown.
  • two barrel ends are provided that are arranged opposite one another in a circumferential direction U of the support barrel. Said barrels engage with each other in a positive fit acting in the circumferential direction.
  • the crimp barrel prepared for crimping describes an initial state of the crimp barrel in which the crimp barrel has not yet been deformed for crimping onto the electrical conductor.
  • the solution according to the invention optimizes the geometry of the crimp barrel prior to deformation in such a way that the crimp base is first deformed during crimping so that the curvature diameter of the first curvature adapts to the curvature diameter of the second curvature.
  • the electrical conductor is pressed against the support region by the crimp wings before the crimp wings are bent over in a final step. It can be ensured in this manner regardless of the crimping tool that the electrical conductor is pressed against the support region during the crimping process, in particular before the crimp wings are bent over, thus preventing individual strands or shielding wires from getting caught in a crimp seam between the two crimp wings. Since the crimp barrel for crimping is adapted to the predetermined diameter or a predetermined diameter range, specially optimized crimp barrels can be provided for different electrical conductors.
  • the support region may be spaced on both sides from the respective regions with the second curvature.
  • the crimp base may extend beyond the support region in a circumferential direction along which the support region is curved having the first curvature.
  • the crimp base has an end-to-end curvature in the circumferential direction so that the crimp base forms a depression.
  • the electrical conductor may automatically align itself in the circumferential direction by sliding along an inner wall of the crimp base in the support region, even if it is initially positioned incorrectly.
  • the crimp barrel may preferably be curved in the circumferential direction and receive the electrical conductor in an axial direction.
  • at least the support region may have a convexly curved support area.
  • the crimp wings are arranged on both sides in the circumferential direction on the crimp base, wherein the region with the second curvature is a section of the respective crimp wing adjoining the crimp base.
  • the curvature diameter of the first curvature may be greater than the predetermined diameter of the electrical conductor.
  • a secant between two ends of the crimped base disposed opposite each other in the circumferential direction may preferably be greater than the predetermined diameter. This can ensure that the electrical conductor can be pressed flat against the support region without resistance from the crimp base.
  • the support region may extend in the axial direction to a separating web.
  • the separating web may be intended, for example, for better handling of the crimp barrel and for resting on the crimping tool. During the crimping process, the separating web may be removed from the remainder of the crimp barrel, for example, by cutting it off or punching it out.
  • the curvature diameter of the second curvature may correspond substantially to the predetermined diameter.
  • the respective region may nestle against an outer surface of the electrical conductor during the crimping process without having to be deformed.
  • the regions having the second curvature may exhibit a greater rigidity as compared to the support region, in particular the crimp base, and the crimp wings. If the regions form a section of the crimp wings, then the respective regions may exhibit a greater rigidity than the remainder of the respective crimp wings. This ensures that the regions are not significantly deformed during the crimping process.
  • the crimp base is bent over until the regions nestle against the outer surface of the electrical conductor and the curvature diameter of the crimp base corresponds approximately to the predetermined diameter.
  • the wings are bent over so that the crimp barrel engages around the electrical conductor.
  • Greater rigidity may be generated, for example, in that at least the regions have at least one corrugation, that is to say, depressions or elevations introduced that are introduced perpendicular to a surface.
  • the at least one corrugation may be shaped, for example, as a reinforcing rib protruding radially on a convexly curved inner surface of the regions.
  • two reinforcing ribs may be provided spaced from one another in the axial direction.
  • the electrical conductor may be additionally axially affixed by the reinforcing ribs.
  • the axial fixation may be further improved if the corrugation is as sharp as possible.
  • the corrugation may be realized with various methods, the corrugation may in particular be embossed.
  • At least one corrugation may extend, preferably end-to-end, in the circumferential direction away from one region to the other region over the crimp base and/or the support region. While this may increase the rigidity of the crimp base, this, however, may be compensated for by different measures.
  • the material thickness of the crimp wings may be adapted such that the crimp base is still less rigid than the crimp wings and/or the regions.
  • the rigidity of the crimp base may be reduced by a recess in the crimp base.
  • the recess may extend preferably from one end of the crimped base in the circumferential direction toward the opposite end.
  • the recess may be configured to be elongate in the circumferential direction and have a uniform depth in the radial direction transverse to the circumferential direction.
  • the recess may penetrate the crimp barrel in the radial direction, thereby forming a window framed by the remainder of the crimp base. Due to the recess, the rigidity of the crimp base may be greatly reduced without great effort, whereby an increase in rigidity caused by the corrugation may be balanced.
  • the recess may be arranged in the axial direction between two corrugations.
  • the recess may preferably have a central axis extending in the circumferential direction and at the same time forming an axis of symmetry for the crimp barrel. It may then be ensured that the crimp barrel is uniformly deformed in the axial direction during the crimping process.
  • the crimp wings or the remaining portion of the crimp wings may extend substantially in a rectilinear manner away from the respective region to a free end.
  • the crimp wings or the remaining portion of the respective crimp wings in an initial state prior to crimping may preferably extend at angles inclined away from one another, so that a clear width between the oppositely disposed crimp wings widens towards the free end. This may prevent individual strands or shielding wires from getting caught on the crimp wings when the electrical conductor is inserted into the crimp barrel. This may be realized, for example, in that the region with the second curvature extends at an angle of up to a maximum of approximately 90°.
  • the crimp wings may have positive-fit elements that are complementary to one another.
  • the positive-fit elements may preferably be arranged at the respective free end and by way of a positive fit prevent the crimp barrel from opening in that the crimp wings move in opposite circumferential directions.
  • the complementary positive-fit elements may be formed, for example, by mutually engaging tabs. At one free end, for example, two tabs may be arranged spaced from one another in the axial direction with shoulders projecting toward one another in the axial direction. Two complementary tabs which may be inserted between the tabs at the first free end and which are each provided with shoulders projecting away from one another in the axial direction may be integrally formed at the other free end. The shoulders of the tabs and the complementary tabs may then create a positive fit in the circumferential direction.
  • a crimp assembly may comprise an electrical conductor with a predetermined diameter and a crimp barrel according to one of the preceding configurations.
  • the crimp base may comprise a support region having a curvature, the curvature diameter of which is greater than the predetermined diameter.
  • the regions with the second curvature may preferably have a curvature diameter which corresponds substantially to the predetermined diameter.
  • the crimp wings or the remaining portion of the respective crimp wings, respectively, may press the electrical conductor against the support region during the crimping process before the crimp wings are bent over in a final step of the crimping process and likewise nestle against the outer surface of the electrical conductor.
  • the electrical conductor may preferably have a cross-sectional geometry in a sectional plane transverse to the axial direction, which is almost identical before and after crimping.
  • the crimp may be, for example, an O-crimp, an overlap crimp or a surrounding crimp. Consequently, the crimp barrel may serve as a support barrel and be configured in such a manner that it does not penetrate into the conductor or its insulation.
  • a crimp barrel 1 according to the invention prepared for crimping is explained in more detail below with reference to Figs. 1 to 4 .
  • Crimp barrel 1 may be configured as a shield crimp and be used as a support barrel 2. Consequently, crimp barrel 1 may be crimped to an electrical conductor 3, for example, as a surrounding crimp, an overlap crimp or as an O-crimp. Support barrel 2 may be used in the crimped region as a support for a further crimp connection, for example, for terminating electrical conductor 3.
  • a crimp assembly 52 may comprise electrical conductor 3 and a crimp barrel 1 according to the invention.
  • Crimp barrel 1 comprises a crimp base 6 that is disposed between two crimp wings 4 and that is provided with a support region 8 for electrical conductor 3, wherein support region 8 has a first curvature 10. Furthermore, disposed on both sides of support region 8 in a circumferential direction U, in which at least support region 8 is curved, is a region 12 having a second curvature 14, wherein a curvature diameter of second curvature 14 is smaller than a curvature diameter of first curvature 10. It is further provided that a rigidity, in particular a flexural rigidity, in support region 8 or even in entire crimp base 6 is less than a rigidity, in particular a flexural rigidity, in respective crimp wings 4.
  • the first deformation may take place at the support region, in particular at crimp base 6.
  • crimp base 6 is bent around electrical conductor 3 while crimp wings 4 press the electrical conductor against support region 8. It is then possible to prevent individual strands or shielding wires of the electrical conductor from getting caught in a crimp seam between two crimp wings 4 during crimping or even from protruding in the radial direction. Consequently, a risk of incorrect production during crimping may be reduced, even without a special crimping tool.
  • Crimp barrel 1 may preferably be formed integrally as a monolithic component, for example, by way of a punching and bending process.
  • Regions 12 may each be spaced from support region 8 in circumferential direction U.
  • Crimp base 6 may extend away over support region 8 on both sides in circumferential direction U and preferably adjoin respective regions 12 on both sides in circumferential direction U.
  • Regions 12 may preferably represent a section 16 of respective crimp wings 4, wherein regions 12 adjoin crimp base 6 and a remaining portion 18 of respective crimp wings 4 extend away from respective regions 12 to a free end 20, in particular in a rectilinear manner.
  • Crimp base 6 may be curved continuously in circumferential direction U having first curvature 10 from an end 22 adjoining a region 12 to an end 22 adjoining oppositely disposed region 12.
  • a depression 24 is formed with a convexly curved inner surface through which electrical conductor 3 automatically slides to support region 8 located at the extremum.
  • crimp base 6 may be precisely distinguished from regions 12 by the change in curvature.
  • Crimp barrel 1 may in particular be convexly curved in a transverse direction Q and extend in a rectilinear manner in an axial direction A perpendicular to transverse direction Q. As a result, crimp barrel 1 forms a trough 26 into which the electrical conductor may be inserted in axial direction A.
  • a secant 31 extending from one end 22 of the crimp base to other end 22 of the crimp base may preferably be longer than predetermined diameter 30 of electrical conductor 3, as shown in Fig. 2 . It may thereby be ensured that electrical conductor 3 may be inserted into crimp barrel 1 without any problems prior to crimping and may be pressed against support region 8.
  • the curvature diameter of first curvature 10 may preferably be greater than predetermined diameter 30.
  • crimp base 6, in particular support region 8 may extend to a separating web 28 in an axial direction A, transverse to circumferential direction U.
  • Separating web 26 may be used, for example, for better handling of crimp barrel 1 and may be removed during the crimping process by, for example, punching or severing, so that at most a stub is still arranged on crimped crimp barrel 1 after the crimping process.
  • Second curvature 14 may have a curvature diameter which substantially corresponds to a predetermined diameter 30 of electrical conductor 3. As a result, region 12 may nestle against an outer surface 32 of electrical conductor 3 during the crimping process without deformation.
  • regions 12 may exhibit greater rigidity, in particular flexural rigidity, as compared to crimp base 6 and crimp wings 4.
  • regions 12 are part of respective crimp wings 4.
  • regions 12 may exhibit greater rigidity, in particular flexural rigidity, as compared to respective remaining portion 18, i.e. respective free end 20 of respective crimp wing 4.
  • the rigidity, in particular the flexural rigidity, of regions 12 may be increased by a corrugation 34 in the form of an embossed reinforcing rib 36.
  • reinforcing rib 36 may be embossed in a jacket surface 38 of crimp barrel 1 facing radially outwardly so that a depression is created on jacket surface 38, and reinforcing rib 36 protrudes on the inner surface of crimp barrel 1 facing radially inwardly, in particular of regions 12.
  • Several reinforcing ribs 36 may also be provided.
  • reinforcing ribs 36 may serve to axially affix electrical conductor 3, in particular if they are sharp-edged.
  • a recess 40 extending between the two ends 22 of crimp base 6 in circumferential direction U is provided according to the exemplary embodiment.
  • the recess may also be provided independently of reinforcing ribs 36 on crimp base 6.
  • Recess 40 may preferably be arranged axially centrally between the two reinforcing ribs 36 so that a central axis 42 of recess 40 running in circumferential direction U is arranged in a plane of symmetry transverse to axial direction A. This may prevent the bending behavior of crimp barrel 1 from being different in axial direction A, as a result of which non-uniform crimping in axial direction A occurs.
  • Recess 40 may be configured, for example, as a depression or, as may be seen in the figures, as a window 44 which penetrates crimp base 6 in the radial direction.
  • Crimp wings 4 or remaining portion 18 of respective crimp wings 4, respectively, may extend substantially in a rectilinear manner away from respective region 12.
  • An angle by which region 12 extends has a preferably maximum of approximately 90° so that crimp wings 4 are inclined away from one another.
  • a clear width between crimp wings 4 may widen in the direction toward free end 20. This prevents individual strands and/or shielding wires of the conductor from getting tangled on crimp wings 4 or being deflected by crimp wings 4 when electrical conductor 3 is inserted prior to crimping.
  • Crimp wings 4 may be provided on their side facing away from oppositely disposed crimp wing 4 with an outwardly facing ramp surface 48, wherein the ramp surface 48 is configured to glide along a mating surface of a crimping tool.
  • a force may be exerted on crimp wings 4 in a first step, wherein a bending moment generated by the force exceeds the flexural rigidity in crimp base 6. This results in a plastic deformation of crimp barrel 1 at crimp base 6, wherein crimp base 6 is bent around electrical conductor 3.
  • Crimp wings 6 there press electrical conductor 3 against support region 8 without deforming, as shown in Fig. 3 .
  • Crimp wings 4 may then be bent around electrical conductor 3 in a second step of the crimping process, so that crimp barrel 1 engages around electrical conductor 3.
  • crimp wings 4 may comprise positive-fit elements 50 which are complementary to one another at their respective free ends 20.
  • Mutually complementary positive-fit elements 50 may be configured as tabs 51 engaging behind one another so that crimp wings 4 opening in circumferential direction U away from one another may be prevented by a positive fit.
