Definitions

  • the invention relates to a crimping tool especially for crimping sleeves, insulated or not, intended for the connection of electric cables.
  • Known pliers in particular that described in document FR-A-1 276 554, usually have two jaws which remain open in the rest position and move together by rotation for crimping. In the open position of the jaws, the crimp sleeve is not held; it is therefore necessary to position and hold it by hand until it is clamped by the jaws.
  • the object of the invention is to produce a crimping pliers comprising jaws closed in the rest position so as to allow the crimping sleeve to be positioned in the pliers before crimping, freeing a hand of the operator who can thus hold the pliers. 'one hand.
  • this pliers intended to crimp a sleeve on a cable conventionally comprises jaws coupled to one another so that one is movable relative to the other, a cam driven by a ratchet wheel actuating a toggle device acting itself on the movable jaw in the closing direction, a pawl mounted on the movable handle so as to drive the ratchet wheel step by step during movements of the movable handle.
  • the crimping tool comprises a movable matrix sliding in fixed rectilinear grooves towards the fixed jaw, on closing, in order to ensure crimping, the toggle device rotating the movable jaw which pushes the mobile matrix, a connection between matrix and jaw ensuring the removal of the mobile matrix when the clamp is opened.
  • the movable jaw in the rest position, the movable jaw is closed under the action of a spring acting on the toggle device, a trigger making it possible to press the toggle device while opposing the spring to ensure a separation of the movable jaw which allows the insertion of the sleeve to be crimped between the jaws, the release of the trigger ensuring the maintenance of the sleeve in the crimping position in the pliers.
  • the clamp comprises a fixed jaw 11 and a movable jaw 12 controlled by a movable handle 13.
  • the movable jaw 12 rotating around an axis 12a, acts on a matrix 14 with axial displacement in a groove of the fixed jaw 11 and in a groove of a wearing part 10 fixed to the housing of the clamp.
  • This displacement is obtained for the axial crimping of a sleeve (not shown), from the displacement of the handle 13 by means of a cam 15 integral with a toothed wheel 16, mounted on an axis 16a, in advance step by step by ratchet 17 mounted on an axis 17a of the handle 13 and biased by a spring 17b.
  • the crimp sleeve is held in the pliers between a fixed die 18 and the movable die 14; the triggering of a trigger 19 makes it possible to move the movable jaw 12 by action on a spring 25 hooked by an axis 25a at one end 20b of the link 20 and consequently the movable matrix 14 to release the sleeve.
  • the trigger 19 acts on the link 20 which unlocks the movable jaw by tensioning the spring 25.
  • the clamp preferably comprises a double cam 15 which acts on the same roller 21 of a toggle formed by two links 20 and 22. It suffices to '' a 180 ° movement of the cam to perform the crimping operation - a full 360 ° revolution of the cam allows two crimping operations to be carried out, which halves the number of operations of the movable handle.
  • the double cam 15 acts on the movable roller 21 integral with the two links 20, 22 one of which 22 pivots on a fixed axis 22a and the other 20 pivots on an axis 20a of the movable jaw 12 which it pushes in the direction closing the movable jaw.
  • the latter comprises at its end a semi-cylindrical part 23 bearing on a side of the movable matrix 14, which slides in grooves according to an axial displacement.
  • the links 20, 22 can be double as shown in FIG. 2.
  • the double cam 15 is integral with one or two toothed wheels (16, 16b) disposed on each side of the cam, with advance pawl 17 and retaining pawl 24, the latter pivots on an axis 24a and is biased by a spring 24b.
  • the double cam 15 advances step by step, always in the same direction, when the movable handle 13 which operates on the advance pawl 17 fixed on its lever arm by the axis 17a.
  • the tension spring 25 of the movable jaw keeps the dies in the closed position on the crimp sleeve.
  • the action of the trigger 19 has the effect of bringing the movable roller 21 of the rod system into the hollow 32 of the double cam 15 by tensioning the spring 25.
  • the clamp is produced in the form of two flanges 27, 28 of light alloy or of plastic material trapping the mechanism itself.
  • the mechanism can be positioned in a flange, then place the second flange on the first, and then the two flanges are locked with screws or a hook. The assembly is thereby facilitated.
  • the guide 10 serving as a wearing part is fixed interchangeably on the movable matrix.
  • a flexible rubber ring 30 stops the double cam 15 in a fixed position after the end of each half-stroke of the cam.
  • the clamp has insulating handles 31 fitted on the fixed 33 and movable 13 handles for working under tension.
  • the establishment of a sleeve in the clamp is carried out by pressing the trigger 19 so as to separate the movable matrix from the fixed matrix. Once the sleeve is positioned, the trigger is released and the sleeve keeps its position in the clamp, clamped between the dies under the action of the spring 25.
  • the crimping is carried out by acting on the movable handle 13 with return spring 34, which advances the gear 16 step by step and consequently the cam 15 which is integral with it. This step-by-step progression from the half-cam 15 produces a large closing force from the movable die to the fixed die and crimps the sleeve.
  • the second half-cam allows a second crimping to be carried out.
  • Maintaining the crimp sleeve between the dies makes it possible to position it with better precision before crimping. It also frees one hand from the operator.
  • the clamp can thus be held with one hand by the operator while the sleeve is held between the jaws of the clamp under the action of the tension spring 25.
  • an auxiliary release trigger 36 mounted on the axis 17a and slightly protruding from the movable handle.
  • This trigger 36 comprises a lug 36a which engages in a return spoiler 17c of the advance pawl 17.
  • the spoiler 17c is arranged so as to lift the pawl 17 out of the teeth of the toothed wheel 16 and to make it repel the retaining pawl 24 outside the teeth of the same toothed wheel 16, when the trigger 36 is actuated, here by pressure, and when the movable handle 13 is pressed towards the fixed handle 33.
