Definitions

  • the present invention relates to an insulating ratchet wrench, of the type comprising a body, a rotor of which one end is engaged in the body, a cap covering the body, a partial covering element of the rotor such as a socket, and a electrical insulation covering these various parts.
  • a key is described in particular by DE-U-80 25 835.
  • the object of the invention is to produce a ratchet wrench whose insulation meets the above standard while having a long service life due to almost no friction.
  • the ratchet wrench conforms to the characterizing part of claim 1.
  • the ring is advantageously manufactured by a process allowing its outer dimension to be adjusted very precisely, that is to say to a fraction of a millimeter.
  • this insulating ring can be obtained by molding, bar turning or other similar process.
  • the existence of a slight clearance between this ring and the rotor avoids any friction generating premature wear of the insulation on the rotor.
  • Figure 1 is a mid-sectional mid-elevation view of an embodiment of the insulating ratchet wrench according to the invention.
  • Figure 2 is a partial exploded perspective view of the key of Figure 1, showing in particular the insulating plastic ring.
  • the insulating ratchet wrench shown in Figures 1 and 2 comprises a body 1 for manual gripping of the key, terminated by an annular part 2, a rotor 3 provided with a radial flange 4, and of which a first end 5 is received in the opening of the annular part 2.
  • the opposite end 6 of the rotor 3 is engaged in a partial covering element of the rotor 3, namely a sleeve 7 in this example.
  • a cap 8 covers the terminal part 2, and contains a ratchet mechanism known per se, not shown.
  • an electrical insulator namely on the body 1 a coating 9 which ends under the annular part 2 by a circular lip 11 forming a sort of skirt coaxial with the axis XX of the rotor 2 and the cap.
  • An insulating layer 12 also covers the sleeve 7 and ends, at the level of the lip 11, by a ring 13 inside the latter.
  • the cap 8 is coated with an insulating cap 14 which completes the isolation of the key.
  • an insulating ring 15 made of a suitable plastic material, surrounding the part 3a of the rotor 3 left free by the covering element 7, that is to say the cylindrical part 3a of the rotor 3 between its ends 5 and 6.
  • the ring 15 is provided with a terminal flange 16 in the form of a cup adapted to follow the contour of the flange 4, and consisting of a part 16a extending radially and an end ring 16b extending in the axial direction.
  • This flange 16a, 16b fits into a corresponding clearance in the insulating coating 9, to which it is fixed, substantially at the level of the circular lip 11, with a slight clearance, relative to the surface of the rotor 3.
  • annular groove 17 is formed in the outer surface of the ring 15, and this groove 17 receives a first annular bead 18 insulating and waterproof, forming part of the insulating layer 12, forming an internal projection of the collar 13.
  • the insulating cap 14 has an annular groove 19 receiving a second annular insulating bead 21 forming part of the insulator 9, with respect to which it projects internally.
  • the two cords 18 and 21 are applied in the respective grooves 15 and 19 in a sealed manner.
