Definitions
- the invention relates to a crimping claw of an electrical contact element made from a stamped sheet metal part for crimping an electrical flat ribbon conductor according to the preamble of claim 1.
- Foil conductors or ribbon cables generally have a plurality of relatively thin ribbon-shaped metallic conductor tracks arranged parallel to one another at a distance from one another and embedded in an insulating material tape in an electrically insulated manner.
- the conductor tracks can be arranged on the surface or in the interior of the insulating material strip.
- the invention is concerned with the electrical contacting of the conductor tracks of such flat ribbon flat conductors.
- a crimping claw of an electrical contact element is known from DE 25 00 556 C2, the claw arms of which penetrate the insulating material, embrace the longitudinal edges of the flat conductor and are rolled up against a longitudinal curvature of the bottom of the crimping claw, which surrounds the likewise rolled up longitudinal edge area.
- a flat contact is made in an arc region between the arc-shaped inner surface of the respective rolled-in claw arm and the underside of the rolled-in longitudinal edge region, which is freed from the insulating material during crimping.
- the tip areas of the claw arms penetrate the flat conductor and each ensure a second contact point (DE 25 00 556 C2, FIG. 3).
- This known crimping claw requires high crimping forces in particular for the penetration of the flat conductor.
- restoring forces which occur after the crimping claw has rolled in can cause the claw arms to spring back, with the result that the penetration contact and / or the flat contact are impaired. In this way, gas-tight contacting cannot be permanently achieved.
- a similar crimping claw is known from US-FS 5,137,468, FIGS. 5 to 7, but is rolled up in such a way that the arcuate outer surface of the rolled-up tip regions of the claw arms contact the upper side of the longitudinal edge region of the flat conductor, the tips of the claw arms during crimping insulating material from the flat conductor scraped off.
- the flat ribbon conductor with the convex arch of the respective claw arm is pressed against the flat conductor supported on the convex arch of the floor arch in the transverse groove area.
- the object of the invention is to provide a crimping claw for crimping a flat ribbon conductor, the contacting of which cannot be impaired by restoring forces.
- FIG. 1 shows a perspective top view of a first embodiment of a crimping claw according to the invention, in which the claw arms of one side are not shown;
- FIG. 2 shows a cross section through the crimping claw according to FIG. 1 in the transverse groove area
- FIG. 3 shows a perspective top view of a further embodiment of a crimping claw according to the invention, in which the claw arms on one side are likewise not shown;
- Fi. 4 shows a cross section through the crimping claw according to FIG. 3 in the transverse illustration
- FIG. 5 shows a longitudinal section through a third embodiment of a crimping claw according to the invention.
- Fig. 6 is a top perspective view of an electrical contact element with a crimping claw according to the invention.
- Fig. 7 shows a cross section through a rolled crimp claw with flat ribbon conductor, contacting on copper open area opposite a first slope in the crimping claw;
- FIG. 8 shows a cross section through a rolled-up crimping claw with a flat ribbon conductor, contacting on a copper free surface opposite a second inclined surface in the crimping claw;
- FIG. 10 is a perspective view of a crimping claw according to the invention with another contact area 2 *,
- An electrical contact element made from a stamped sheet metal part generally has a contact area 2 and a crimp area 3, which are connected to one another in one piece via a transition area 4 (FIG. 6 ⁇ .
- the spatial shape of the contact area 4 can be arbitrary, which is why it is part of the Description of the present invention is not considered.
- the crimping area 3 has a crimping claw 5, which is designed for crimping a flat ribbon conductor 27.
- the crimp claw 5 consists of an essentially elongated flat base plate 6 with the longitudinal edges 7 and S, a free end edge 9 and a surface 10 and a lower surface 11.
- Claw arms 12 which are angled approximately at right angles and protrude above surface 10, are connected to longitudinal edges 7, S.
- the claw arms 12 on the two longitudinal edges 7, 8 are not arranged opposite one another in the transverse direction of the base plate 6, but are offset diagonally.
- the sixth has, for example, on one longitudinal edge 7 two claw arms 12 and on the other longitudinal edge 8 three claw arms 12 each in a longitudinal row.
- a gap 13 is provided in each row between two claw arms 12.
- a claw arm 14 is connected to the other longitudinal edge.
- the number of claw arms 12 and the gaps 13 can be selected; in the simplest case, two diagonally opposite claw arms 12 are sufficient.
- the claw arms 12 have a tongue shape and terminate in a rounded tip region 16, which is expediently embossed wedge-shaped with a flat outer surface that is beveled towards the free end.
- the approximately triangular tongue shape of the claw arms 12 results in approximately V-shaped to U-shaped hatches 13, so that the gaps 13 have approximately the negative shape of the claw arms 12.
- a bead 14 Arranged in the transverse center of the base plate 6 between the claw arms 12 is a bead 14 which extends in the longitudinal direction of the base plate 6 and projects beyond the surface 10 and which, e.g. can be pushed upwards from the underside of the base plate 6.
- transverse grooves 15 are formed, each of which is positioned opposite a claw arm 12 in the transverse direction of the base plate 6.
- the width of the grooves 15 corresponds approximately to the width of the tip region 16 of a claw arm 12.
- the spatial shape of the bead 14 and the grooves 15 in the transverse direction of the base plate 6 is essential.
- the bead zenite 18 transversely transitions over a convex cylindrical arch surface 17 into a flat, sloping first surface 1 $ that slopes steeply towards the base plate 6, to which a second flat, inclined surface is formed , slightly flat to the bottom plate 6, merging into the latter surface 20 connects.
- the angle of the surface 19 to the flat surface 10 of the base plate 6 is preferably between 50 and 70 °.
- the angle also lies between the surface 20 and the surface 10 of the base plate 6, preferably between 20 and 40 °.
- the groove bottom has a groove zit 21, which transversely merges via a convex cylindrical arch surface 22 into an inclined, flat surface 23 that slopes steeply towards the base plate 6, to which another flat, inclined surface, which slopes somewhat flatly, into the latter merging surface 24 connects.
- the angle of the surface 23 to the flat surface 10 of the base plate 6 is between 50 and 70 °. In addition, the angle between the surface 24 and the surface 10 of the base plate 6 is between 20 and 40 °.
- the grooves 15 extend across the entire bead 14.
- the groove configuration according to the invention is only necessary on the side on which the groove 15 has a claw arm 12 arranged opposite, because this claw only interacts with this groove half.
- the invention provides that the respective claw arm 12 is rolled in such a way that its outer surface is pressed against the bead 14 and the groove 15 on its long side next to the longitudinal center 26, a flat ribbon conductor 27 being arranged in between.
- the rolling radius of the claw arm 12 is matched to the angle of the bevel 19 and / or 23 to the base plate 6 such that self-locking of the claw spring arm is brought about in the event of inevitable springback of the claws arm 12 after crimping and / or in the event of a tensile effect on the flat ribbon conductor. This self-locking is illustrated in FIGS. 7 and 8.
- the tip area 16 penetrates the base material 29 of the flat ribbon conductor 27, is gripped by the uppermost part of the crimping tool (not shown) and is deformed in such a way that the tip area 16 preferably in the area of the convex cylindrical arc surface 17 or on the inclined surfaces 19, 20 meets the copper free surface 28 of the flat ribbon conductor 27.
- the flat ribbon conductor 27 is clamped between the outer surface of the claw arm 12 and the surface 19 (FIG. 7) and / or the surface 20 (FIG. 8). The contact is made via the outer surface of the claw arm 12 and the top of the copper free surface 28 of the flat ribbon conductor 27 "
- FIG. 3 Another embodiment of the crimping claw according to the invention (FIGS. 3, 4) provides that the zenith 18 of the bead 14 coincides with the zenith 21 of the grooves 15. This spatial shape results in a longer run-out slope 24 of the grooves 15 i compared to the run-out slope 20 of the bead 14. This embodiment represents a simplification in terms of production technology.
- the embodiment of the invention according to FIG. 5 provides that the outer edges of the grooves 15 on both sides have a cutting shape and protrude beyond the bead surface, resulting in cutting edges 25. This enables additional contacting of the conductor 30 from the underside.
- the cutting edges 25 penetrate the base material 29 and contact the conductor 30 of the flat ribbon conductor 27.
- the embodiment of the invention according to FIG. 9 provides that the flat ribbon conductor 27 has no copper open area 28.
- the tip region 16 of the claw arm 12 penetrates the cover layer 31 of the flat ribbon conductor 27 and scrapes it off and makes contact with its outer surface on the conductor 30.
- the invention thus creates self-locking of the claw arms in the contacting area after crimping and defined contact zones.
- there is a gas-tight contact zone with flat ribbon conductors of any kind being able to be contacted * »Secure contacting in long-term operation can be guaranteed.
- the contact is made with the outlet arch of the crimping claw, which is supported on a slope, which is formed by the flat conductor, which is on the inclined surface of the Bead and the groove rests.
- the contacting takes place over the inclined surface 19/23 of the bead and / or the groove, wherein in particular the contacting can also take place on the run-out slope of the two elements.
- the inclined surfaces 19, 23 and / or 20, 24 can be curved slightly convex in the direction of the flat ribbon conductor.
