Definitions

  • the invention relates to a cable lug with a tubular receiving portion for the cable, an integrally formed flat part connecting portion which has a hole, and a nut which is held captively, preferably held to be rotatable, on the flat part connecting portion, the nut not passing through the flat part connecting portion and being held by a reshaped holding material portion of the flat part connecting portion which projects into an undercut formed on said nut.
  • the invention also relates to a cable lug with a tubular receiving portion for the cable, an integrally formed flat part connecting portion which has a hole, and a functional part which is held captively, preferably held to be rotatable, on the flat part connecting portion, the functional part being held by a holding material portion which projects into an undercut formed on said functional part, this holding material portion being rooted in a region sunk-in in a step-like manner with respect to the unaffected surrounding region of the flat part connecting portion, the undercut being formed with an axial extent which is equal to or less than the axial extent (thickness) of the unaffected flat part connecting portion.
  • the invention also relates to a method for forming a connection, which is captive but allows axial and possibly rotary movement, of a cable lug to a functional part, such as a nut, the cable lug having a tubular receiving portion for the cable and a flat part connecting portion, and the functional part being pressed into the undeformed flat part connecting portion by penetrating or passing through a hole which is formed therein.
  • the invention relates to a nut, preferably for forming a press-connection with a flat part connecting portion of a cable lug, one end of the nut, in relation to its tightening or loosening direction, having a radially opening undercut which is provided in the axial direction of the nut and has an upper and a lower delimiting surface.
  • the holding material portion is in each case accommodated in the undercut of the nut or the functional part such that said undercut is filled, or the undercut is formed to be very large in the axial direction and formed in one direction by the start of the thread (U.S. Pat. No. 5,256,019).
  • a novel design is sought here, in particular with regard to rotatable retention of the nut or the functional part.
  • a nut which can be used advantageously in an item comprising a combination of cable lug and functional part, such as a nut, or when carrying out a method for forming a connection between a functional part, such as a nut, and the cable lug.
  • the object is achieved on the basis of the above-described state of the art in that it is provided that the holding material portion is accommodated in the undercut with an axial clearance.
  • a radial play may also be possibly provided.
  • this is advantageous with respect to thermal loading of the connection.
  • certain changes in volume which are attributable, for example, to different material expansions when heated, can advantageously be accommodated.
  • the design solution is itself also inherently directly suited to realizing a rotatable mounting of the nut.
  • the inventive concept can, in principle, also be implemented by rotatability being prevented in a positively locking manner, for example by rotation-prevention projections which extend vertically in the seat region of the nut and can be overcome by being lifted.
  • a functional part in generic terms is provided, the object is achieved with a cable lug in which provision is in particular made for the step-like sunk-in region to be rotationally symmetrical and have a conical portion which is open outward and upward and has at least one conical surface.
  • the combination of the rotationally symmetrical form with the outwardly and upwardly open conical portion functions effectively against possible undesired jamming of the functional part in the cable lug. Undesired jamming does not at the same time mean also that prevention of rotation cannot nevertheless still be present.
  • the invention provides for a rotationally symmetrical circumferential step-like area to be formed in the flat part connecting portion in the course of the pressing-in process, at least one of the step surfaces being formed as a conical surface running at an acute angle to a horizontal or a vertical.
  • the perpendicular step surface or the step surface which, according to the invention, opens obliquely outward is substantially realized by the deformation.
  • a certain elastic reverse deformation is correspondingly produced following conclusion of the pressing-in process, this elastic reverse deformation tending to lift the functional part.
  • the functional part can be positioned largely free from the step surfaces, and this is advantageously beneficial for the rotatability of the functional part which may possibly be desired.
  • the object is achieved with an item in which it is substantially provided that the undercut is formed to be rotationally symmetrical and the upper delimiting surface is part of a rotationally symmetrical stepped area which is formed on the nut.
  • the upper delimiting surface of the undercut runs directly into said stepped area, which finally always opens upward and outward.
  • step surface which runs at an acute angle to the perpendicular once again runs into a horizontal surface.
  • This horizontal surface is accordingly disposed radially outside said step surface.
  • the undercut which is formed on the nut or the functional part is formed in a region which—at least in relation to the nut—does not have an associated (internal) thread.
  • the holding material portion is preferably rooted in a portion of the flat part connecting portion which has been sunk-in in a step-like manner with respect to a surrounding region of the flat part connecting portion.
  • step surfaces are planar, independently of their oblique orientation relative to a horizontal or vertical.
  • the lower delimiting surface of the undercut it is also preferred for the lower delimiting surface of the undercut to extend in a vertical projection over more than half of the associated stepped area in the radial direction, said stepped area being formed at the lower end of the associated actual nut part or head of the functional part.
  • This undercut is also preferably formed independently of the thread and so as not to (radially) overlap a thread of the nut.
  • the inner face of the undercut region is formed to be cylindrical in the case of the nut.
  • the relevant cylindrical surface preferably merges into the root of the internal thread which is formed in the nut.
  • the undercut In the axial direction, the undercut preferably extends over a quarter or more of the thickness of the flat part connecting portion.
  • the angle—which results in a conical surface—of the rising portion of the stepped area is preferably an acute angle, more preferably in the range of 1 to 60 degrees, still more preferably in the region of 45 degrees.
  • the disclosure also includes all relevant intermediate values, for example 2, 3 degrees or 46, 47 degrees etc.
  • the stepped area has a step surface which is oriented on a horizontal and a step surface also runs at an angle to the horizontal
  • this angle is preferably also an acute angle, more preferably in the angular ranges specified above in relation to the rising portion of the stepped area, and to be precise, the angle can in this case be formed such that it counts both positively and negatively.
  • the angle of the step surface which is oriented to the horizontal to always be selected to be smaller (in terms of magnitude) than that of the step surface which is oriented to the vertical.
  • the nut with said shaped portions can be produced as a turned part. However it may also be produced, for example, as an extruded part, said neck portion being integrally formed at the bottom initially in the form of a cylindrical tube, and then in a second step being upset such that the required and described undercut is produced.
  • the cable lug is preferably one which is formed from a solid material, the flat portion then being pressed by reshaping.
  • connection between the nut, which is generally composed of a steel material, or another functional part, and the flat portion of the cable lug is also assisted by the cable lug usually consisting of a comparatively soft material, specifically copper or aluminum.
  • pressing-in produces a characteristic compression curve, in first instance specifically with force rising in a comparatively linear manner along the path and then angling off in a second portion of the compression curve in which the force rises more sharply as plotted over the path.
  • This characteristic allows compression to be controlled in an advantageous manner in relation to the pressing force applied. It is possible to prespecify a typical pressing force which is located to a sufficient extent in the steep region of the curve, and be sure that mounting of the functional part on the cable lug appropriately for its function is achieved in each case when this pressing force is reached.
  • the hole in the cable lug is formed with a hole step.
  • the hole step is preferably already provided before the deformation. This is advantageous in respect of connection to a pin on which, in one application, the cable lug is for example to be fitted.
  • This pin which has a thread at its head end, has a radial projection below the thread.
  • the cable lug outside the hole sits on this area. In order to be able to utilize this projection as advantageously as possible in terms of area, it is recommended to make the hole narrower in the lower region which faces the pin, that is to say to provide it with the said hole step.
  • the horizontal surface in terms of the functional part, in particular the nut, it is also preferred for the horizontal surface to have a circular outer contour.
  • a conventional nut with a polygonal contour that is to say for example a hexagonal contour
  • the top end of this flange has a fitting area which can advantageously be used by a corresponding pressure-exerting tool.
  • the outer contour being round, the desired rotatability of the nut cannot be prevented, for example by a hexagonal depression due to said nut being pressed into the surface of the flat part connecting portion of the cable lug.
  • the functional part in question may also be a screw. Furthermore, it may also be for example a sleeve or a mandrel.

  • the cable lug 1 has a tubular receiving portion 4 and a flat part connecting portion 5 .
  • the cable 19 is introduced into the tubular portion 4 and then held therein, for example by a press fit, the intention being for electrically reliable connection to be achieved by means of the cable lug 1 .
  • the cable lug 1 which is formed from a solid material in the exemplary embodiment, also has a hole 6 in the already mentioned press-deformed flat part connecting portion 5 .
  • the nut 2 is inserted into this hole 6 and then connected to the cable lug 1 , that is to say specifically to the flat part connecting portion 5 , in a captive but rotatable manner, by being pressed down in the manner still to be described.

  • the vertical surface 13 merges in a radially outward direction into a horizontal surface 14 which, however, is formed with a varying radial extent over the circumference on account of the hexagonal form of the nut 2 in the exemplary embodiment.
  • This varying radial extent of the horizontal surface 14 can be seen in the illustration according to FIG. 3 , in which the nut 2 is illustrated in a position fitted onto the flat part connecting portion 5 before pressing. In this case, the hole 6 extends partly, still radially, beyond an associated vertical flat surface 15 of the nut 2 .
  • FIG. 4 illustrates a cross-section through FIG. 3 , likewise correspondingly in the state before pressing.
  • FIGS. 5 and 6 illustrate the state following pressing.
  • a holding material portion 16 is formed from the flat part connecting portion 5 , said holding material portion extending into the undercut 9 of the nut 2 .
  • the holding material portion 16 is part of the stepped area which has already been mentioned and is positively formed in the flat part 5 but, in the same way, has the oblique orientation with respect to a horizontal H or vertical V, as already described. In this case, the holding material portion 16 clearly extends radially inward beyond the hole 6 of original diameter which remains in the lower region, seen over the thickness of the holding material portion 16 .
  • the step-like sunk-in region with the step surfaces 17 and 18 which is created in the holding material portion 16 following pressing is formed such that it is rotationally symmetrical over the circumference of the hole 6 . That is to say, the area is produced in a notional sense by rotation of a template. There are no undercuts in the area in relation to the direction of rotation of the notional template mentioned (this is naturally an example of shaping as it is used as required in casting molds; this is only mentioned here in order to make clear the nature of the rotationally symmetrical area).
  • the holding material portion 16 is held in the undercut 9 both with axial and radial play.
  • this play is comparatively small, as can be gathered, in terms of magnitude in the region of the thread depth of the internal thread 7 of the nut 2 , that is to say in the millimeter range or in the range of tenths of a millimeter.
  • the holding material portion 16 itself is also formed to be rotationally symmetrical.
  • the undercut 9 completely laterally overlaps the holding material portion 16 in the pressed state.
  • connection part 20 has a screw pin 21 by means of which the nut 2 , which is captively but rotatably press-connected to the cable lug 1 , is screwed on. In this way, a desired pressure/butting connection is produced between the lower side of the flat part connecting portion 5 and the upper side of the connection part 20 .
  • FIGS. 8 and 9 shows a functional part 3 in the form of pin 22 .
  • Said pin may possibly also be a screw on which a thread can also be formed at the lower end of the undercut 9 .
  • the nut 2 has an upper shaped portion 23 with an annularly circumferential planar pressing area 24 .
  • the required compressive force can be applied to the nut 2 by means of this pressing area 24 using a suitable pressure-exerting tool, in order to form the holding material portion 16 out of the flat part connecting portion 5 of the cable lug 1 in the course of the pressing.
  • the nut is merely pushed into the flat part connecting portion 5 from above, as has also already been described previously.
  • the pressing area 24 is substantially smaller than the projected full surface of the nut 2 . It corresponds at least to less than half of this projected complete surface.
  • the already mentioned plastic part 8 is accommodated within the structure 23 , said plastic part being aligned, in a manner corresponding to a self-locking nut and as can also be seen from the cross-sectional illustration according to FIG. 11 , with the internal thread line of the screw thread 2 on an inner wall, which wall has a cylindrical shape.
  • the horizontal surface 14 does not rest on the flat part connecting portion 5 in the compressed state. Instead, it hovers as it were over the flat part connecting portion when the pressing-in is correct.
  • the pressing force is selected such that, with the given configuration of the stepped area, a pressing-in process is performed only to the extent that the surface 14 does not come to rest on the flat part connecting portion 5 , and preferably also without taking into account the elastic recovery which results after the nut is relieved of the pressing force, that is to say in such a way that the surface 14 does not come into contact with the upper surface of the flat part connecting portion 5 at any time in the pressing process.
  • the hole ( 6 ) is stepped in the axial direction. Starting from a relatively large diameter at the top, which is associated with the functional part, specifically with the nut 3 , the diameter of the hole changes to a smaller diameter toward the bottom by way of a hole step 25 .
  • the hole step 25 is formed symmetrically with respect to the center of a longitudinal axis of the hole.
  • the hole step 25 serves to increase the area on the lower end of the flat part connecting portion in the vicinity of the hole 6 , this because, in one application, the flat part connecting portion, together with the nut 3 , is fitted and screwed onto a stepped pin which has a thread at its upper end.
  • the flat part connecting portion accordingly has to sit on a relatively narrow, annularly circumferential area of the pin. This seating and therefore contact area can advantageously be increased in size by the described hole step 25 .
  • the procedure followed may be, for example, that the upper portion of the hole 6 is pressed in and then, in a second working step, the lower region of the hole is cut or punched out, leaving the hole step 25 . Accordingly, a cut edge can be established in the cable lug in the lower region of the hole and, in contrast, plastic deformation in the upper region.
  • a radial extent r, compare FIG. 15 , of the hole step 25 preferably corresponds to the radial depth T, compare FIG. 11 a for example, of the undercut 9 .
  • said radial depth T of the undercut 9 can also correspond to the vertical height of the vertical surface or the stepped area 13 , 17 in this case.
  • a circumferential compression flange 26 is integrally formed at the lower end of the nut. This compression flange 26 extends from the lower horizontal surface 14 over a height which corresponds to approximately one third of the vertical height of the head of the functional part, here the nut 3 , this height being measured from the horizontal surface 14 up to the pressing area 24 .
  • the pressing area 24 is no longer of primary importance. Said pressing area may also be dispensed with or formed in the manner illustrated in FIGS. 1 to 7 for example.
  • the compression flange 26 serves the purpose of enabling a pressure-exerting tool to be fitted. Relatively high compression forces for press-connecting the functional part or the nut 3 to the cable lug 1 can then be applied by means of this compression flange.
  • the radial extent of the compression flange 26 in relation to a flat face of the polygonal portion of the nut 3 corresponds, in the smallest radial extent, to one twentieth to one fifth of the diameter of the screw 3 , as measured in the region of the polygonal portion and centrally with respect to a flattened portion.
  • the surface, on which the pressure-exerting tool can sit, of the compression flange 26 can run downward in a slightly inclined manner, but can also run horizontally.
  • the vertical height of the hole 6 in the region of the relatively small diameter, that is to say below the hole step 25 as seen from above, is selected such that the lower termination of the undercut 9 of the functional part does not rest on the step in the pressed state either.
  • the screw including the undercut 9 ends, as shown, above the hole step 25 in the pressed state also.
  • the functional part specifically the nut 3 of the last-described embodiment, can also be combined with a hole as is further described above.
  • the functional parts as are further described above can also be combined with a hole as is explained in relation to the last-described exemplary embodiment.
