Definitions

  • the present invention relates to a perfected retaining element of the strip kind, specifically for fastening, e.g. to the underbody, axially symmetrical components, typically electric harnesses formed by one or more cables, also of relatively and reciprocally very different diameters and/or pipes passed through by fluids for on-board vehicle systems, such as gasoline or oil.
  • the strip of the known retaining elements of the above-described type is not however capable of optimally- fastening harnesses formed by cables of reciprocally different diameter or, above all, by electric cables arranged within a corrugated tube; loosening or displacements of the cables/harnesses, which may cause annoying noise or vibrations, may thus be generated in use.
  • a retaining element for axially symmetrical components such as electric cables/harnesses or pipes, which allows an effective fastening action, free from noises and vibrations, also in the case of harnesses formed by multiple electric cables of different diameter, and above all in the case of cables arranged within corrugated tubes or sheaths.
  • a retaining element which presents, at the same time, small dimensions as well as low manufacturing costs and high assembly ease.
  • a retaining element of the strip type for axially symmetrical components, specifically for electric cables/harnesses or pipes, as defined in claim 1.
  • the retaining element comprises a head provided with fastening means to the aforesaid support, e.g. couplable to a hole of the underbody of a vehicle, a flexible strip made integrally with the head and provided on a first face with a rack toothing, and a through seat crossing the head and internally provided with retaining means which are ratchet couplable with the rack toothing of the strip in a locked configuration of the strip, in which this has been loop-folded and inserted with its free end through an inlet of the seat made at a first end of the head.
  • the strip protrudingly extends with a root portion of its own, opposite to said free end, from a second end of the head, opposite to the first, the root portion being arranged essentially flush with an outlet opening of the seat for the strip in the locked configuration of the strip; and the head is provided, on the side of the inlet of the seat, with at least one pair of opposite projections which extend, at least partially, protrudingly perpendicular to the inlet itself.
  • each projection lengthen on a face of the head arranged perpendicularly to the inlet of the seat and on opposite side to the fastening means, and extend perpendicularly from such face, parallel to the root portion of the strip; furthermore, each projection is delimited on the side opposite to the head by an essentially rounded edge defining, in a plane perpendicular to the inlet of the seat, a V profile having uniform height in correspondence with the face of the head arranged perpendicularly to the inlet and progressively decreasing towards the inlet on the side of the inlet itself.
  • the cable bundles are not only clasped by the strip, once this is throughly inserted crossing the seat to form a sort of noose around the components to be fastened, but are also pushed between the projections and against the face of the head perpendicular to the inlet, so as to prevent in use any relative movement; specifically, if the cables are inserted in a corrugated tube or sheath, the projections are inserted between one crest and the other of the corrugations of the tube or sheath, thus firmly fastening the wiring harness, specifically along the direction of extension of the axially symmetric components to be fastened.
  • such a retaining element is of small size, easy to mount and cost-effective to manufacture, due to the essential absence of undercuts.
  • FIG. 1 shows an elevation longitudinal view of a retaining element made according to the invention
  • figure 2 shows a top plan view of the same retaining element in figure 1
  • - figure 3 shows a section view taken along a plotting plane III-III of a detail of the retaining element shown in figure 2;
  • - figure 4 is a section view, in magnified scale, of a detail of the detail in figure 3; - figure 5 shows a section view taken along a plotting plane V-V of a detail of the retaining element shown in figure 1; figure 6 is a section view taken along a plotting plane VI-VI of the retaining element according to the invention, shown in figures 1 and 2; and
  • FIG. 7 is a view in magnified scale of a detail of the retaining element in figures 1 and 2.
  • numeral 1 indicates as a whole a strip retaining element fastenable to a support T, in the case in point consisting of a vehicle body, in a retaining hole F of support T to fasten axially symmetrical components of the vehicle to the same, such as electric cables or harnesses and/or vehicle service fluid feeding pipes, known and therefore not shown for the sake of simplicity.
  • Retaining element 1 comprises a head 2 provided with fastening means 3 to support T, couplable in hole F, a flexible strip 4 made integrally in one piece with head
  • Strip 4 protrudingly extends with a root portion 20 thereof (figure 6), opposite to free end 12, from a second end 22 of head 2, opposite to end 14 and arranged essentially flush with an outlet opening 23 of seat 8 for strip 4 in the locked configuration of the same.
  • head 2 is provided, on the side of inlet 13 of seat 8, with at least one pair of opposite projections 30 (figure 7) which protrudingly extend at least in part perpendicularly to inlet 13 itself. Projections 30 further lenghten on a face 31 of head 2 (figure 6) arranged perpendicularly to inlet 13 and on opposite side to fastening means 3 and extend perpendicularly to face 31, parallel to root portion 20 of strip 4.
  • Each projection 30 is delimited on the side opposite to head 2 by an essentially rounded edge 33 defining a V profile on a plane perpendicular to inlet 13, coinciding with the plane of the sheet in figure 6.
  • Each projection 30 indeed presents a uniform height in correspondence with face 31 and a progressively decreasing height towards inlet 13, in direction perpendicular to the same, up to become nihl in correspondence with a base 36 of head 2 (figure 6 and 7), which seat 8 is made flush with and which the fastening means 3 depart from, on opposite side of strip 4.
  • Fastening means 3 comprise, in the case in point, an anchored-shaped shank 40 (figures 5 and 7), in turn comprising a central stem 41 which protrudingly extends from base 36 of head 2, on opposite side of strip 4, and a pair of elastically deformable arms 42 reciprocally arranged to form a V and which obliquely and radially protrude from a free end of stem 41, opposite to base 36 of head 2, and towards the latter; and an elastically deformable truncated cone shaped flange 44, carried by base 36 of head 2 radially protrudingly therefrom with its concavity facing towards arms 42 of shank 41.
  • Elastically deformable arms 42 present progressively increasingly thickness towards their corresponding free ends, which are provided with corresponding saw toothings 45, also shown in detail and on a magnified scale in the circular frame in figure 5, including a plurality of teeth (thus at least two and preferably three or more) , each of which presents an abutting face 46 arranged facing and parallel to truncated cone flange 44.
  • a plurality of teeth thus at least two and preferably three or more
  • each of which presents an abutting face 46 arranged facing and parallel to truncated cone flange 44.
  • Face 5 of strip 4 provided with toothing 6 faces the same side as inlet 13 of seat 8, when strip 4 is not deformed; and retaining means 10 which are ratchet couplable with rack toothing 6 consist of an elastically deformable arm, which obliquely protrudes within seat 8, from inlet 13 and towards outlet opening 23 of seat 8, from an internal side wall 50 of seat 8 opposite and immediately adjacent to face 31 of head 2.
  • Elastically deformable arm 10 presents an edge 52
  • Strip 4 preferably presents a U cross-section, being longitudinally delimited by opposite side edges 70 (figure 3) of relatively high thickness, teeth 55 being made therebetween, and transversally to strip 4, so that the fluid material intended to form strip 4 may flow faster during the step of moulding.
