Definitions

  • the present invention relates to a cable clamping device, particularly for clamping bundles of electric cables of different sizes.
  • Known cable clamping devices which may be produced and assembled as separate parts, or be integrated in one piece with the terminal boards - comprise a base with a seat through which the cable/s is/are housed; and a pressure member, possibly wedge-shaped, which is inserted inside a mouth in the base facing the seat, to press and so clamp the cable/s by friction against a bottom wall of the seat.
  • the clamping force required is provided by one or more screws, which secure the pressure member to the base, and which, when tightened, ease the pressure member inside the seat through the mouth, so that the same cable clamping device can be used for equally effectively clamping cables of different diameters.
  • Cable clamping devices of the above type - which are normally molded from thermoplastic synthetic plastic resin, so as to be electrically insulating - are unsuitable, however, for'effectively clamping bundles of cables, particularly of different diameters.
  • the pressure of the clamping member on the cables produces an unbalanced reaction, due to the asymmetric nature of the cable bundle, which so deforms the clamping device as a whole as to seriously impair its efficiency or even result in failure of the device.
  • cost and technical considerations rarely enable clamping devices to be made of more rigid materials.
  • a cable clamping device comprising a base having a seat through which one or more electric cables, e.g. supply cables of an electric household appliance, are housed; and a clamping member, which is insertable inside the base, crosswise to said seat, through a mouth formed in the base and directly facing the seat, to clamp said cables against a bottom wall of the seat; characterized in that the clamping member is secured to the base by a jack device comprising a rib formed in one piece with the clamping member and having transverse teeth; and a recess formed in the base, alongside said seat, to receive the whole length of said rib, and having, internally, at least one elastically deformable tooth located so as to click onto said transverse teeth.
  • the cable clamping device preferably also comprises a conventional screw device for securing the clamping member to the base, and located on the opposite side to the jack device.
  • the cable clamping device according to the invention may dispense with the screw, while still preventing accidental movement of the clamping member.
  • the jack device employed in fact, is irreversible, in the sense that, once the required clamping position is reached, the clamping member can only be withdrawn from the seat, as will be seen, voluntarily by the user with the aid of a tool.
  • Number 1 in Figures 1 to 3 indicates a cable clamping device comprising a base 2 having a seat 3, through which are housed one or more electric cables, e.g. a bundle of cables 4a, 4b, 4c for supplying an electric household appliance (not shown) and differing widely in size - in the example shown, in diameter.
  • Cable clamping device 1 also comprises a clamping member 5, which is insertable inside base 2, crosswise to seat 3, through a mouth 6 formed in base 2 and directly facing the seat 3, to clamp cables 4 against a bottom wall 7 of seat 2.
  • Clamping member 5 and base 2 are defined, in the example shown, by respective cup-shaped, substantially parallelepiped-shaped bodies molded from synthetic plastic, preferably thermoplastic, material and insertable the first inside the second.
  • the through seat 3 for cables 4 includes part of an inner cavity 8 of the cup-shaped body defining base 2; and two facing U-shaped openings 9 formed through respective peripheral lateral walls 10 of base 2, with their respective concavities facing mouth 6 of base 2, defined on the open side of the cup-shaped body defining base 2.
  • Clamping member 5 and base 2 are preferably connected integrally to each other by a deformable tongue 11 - shown by the dash line in Figure 1 - so they can be molded in known manner in one operation, with the respective concavities facing the same way, and then positioned, in use, with the concavities facing, as shown in the drawings.
  • base 2 comprises known click-on retaining means 12 for connection to a support 13, e.g. the casing of an electric household appliance, and may be formed as a separate part, or integrally with a body 14 of a known terminal board (not shown for the sake of simplicity), so that device 1 is integrated in the known terminal board.
  • device 1 also comprises a jack device 18, by which clamping member 5 is secured adjustably to base 2, at least partly inside seat 3.
  • Jack device 18 is formed at the end 19 of cable clamping device 1 opposite tongue 11, and comprises an L-shaped rib 20 formed in one piece with clamping member 5 and having transverse teeth 21; and a recess 22 formed in base 2, alongside seat 3, to longitudinally accommodate the whole length of rib 20, and having, internally, at least one elastically deformable tooth 23 located so as to click, in use, onto teeth 21.
  • Clamping member 5 also comprises, on the opposite side to rib 20, at least one hole 24 for receiving a respective screw 25 (shown only partly in Figure 3) or other similar removable fastening member; and base 2 comprises, on the opposite side to recess 22, at least one fastening seat 26 for receiving screw 25, and which is defined, in the example shown, by a tubular stem projecting inside cavity 8, between walls 10 and on one side of openings 9, which are therefore interposed between fastening seat 26 and recess 22.
  • Recess 22 is separated from seat 3 by a wall 29 parallel to seat 3, and is therefore defined by the part of cavity 8 separated by wall 29 from the part of the cavity defining seat 3. Tooth 23 is formed in one piece with base 2 at end 19 and at a mouth 30 of recess 22 aligned with mouth 6 of seat 2.
  • Tooth 23 projects inside recess 22, on the opposite side to and parallel to wall 29, and is defined, towards wall 29, by a sloping surface 33, which extends partly inside mouth 30 so as to at least partly occupy mouth 30 when viewed from above ( Figure 2).
  • Rib 20 projects laterally from clamping member 5 in such a position ( Figures 1 and 3) as to rest, in use, on and astride wall 29, and to interfere with tooth 23 - in particular, by teeth 21 interfering with sloping surface 33 - when clamping member 5 is inserted in the direction of arrow A inside base 2; for which purpose, teeth 21 are formed on the face of rib 20 facing tooth 23 in use.
  • Teeth 21 are serrated, and comprise a number of triangular teeth defined by respective sloping surfaces 34, which, in use, when rib 20 is positioned parallel to wall 29, are oriented parallel to and facing sloping surface 33.
  • member 5 has a contact edge 35, which, in the example shown, is semicircular, but which may be any shape, e.g. wedge-shaped.
  • member 5 is arrested, and tooth 23 engaging teeth 21 holds member 5 in position, and maintains pressure on, and so ensures firm clamping of, cables 4.
  • member 5 is also retained the normal way by means of one or more screws 25.
  • screw 25 if provided, is first removed, and a tool, e.g. a screwdriver 38 illustrated by the fine line in Figure 1, is inserted inside mouth 30 in the sloping direction indicated by arrow C, is pressed against sloping surface 33, and is rotated in the direction of arrow R to flex tooth 23 and so release teeth 21.
  • a tool e.g. a screwdriver 38 illustrated by the fine line in Figure 1
  • rib 20 can therefore also be withdrawn from recess 22.
