Definitions

  • the invention relates to electrical connectors of the type which can be coupled to a complementary connector, having a contact receiving body which carries a threaded rotary locking ring intended to cooperate with a threaded part of the complementary connector, the ring being integral with internal teeth. which has edges separating a face of slight slope from a face of steep slope relative to the circumferential direction, the body of said connector being integral in rotation with latching means cooperating with the bottom of the teeth to constitute a latching s' opposing the rotation of the ring in the direction of unscrewing, for which the latching means abut against the faces of steep slope.
  • a connector is known from document US-A-4,030,798.
  • Such connectors are often called “self-locking” or “preponderantly locking”, in the sense that the torque to be exerted to unscrew the ring is higher than that necessary to tighten it. They find an important application in aeronautics where vibrations risk causing loosening of threaded connections and where bayonet locks are excluded in many cases.
  • the present invention aims in particular to provide an electrical connector of the above type having a simple constitution, making it possible to obtain a high value of the ratio between the screwing and unscrewing couples and this without risk of jamming.
  • the invention provides for this purpose a connector in which said latching means comprise a monobloc ring of synthetic material having an internal immobilization part relative to the body and an external part carrying teeth in engagement with said toothing.
  • the ring has teeth distributed on a radial face and the toothing is formed on a notched washer having a sliding keying with the ring, pushed towards the ring by a metallic elastic member bearing on the ring which retains its elastic properties better over time than a synthetic material member.
  • This metal member may in particular be constituted by a wavy washer, interposed between the notched washer and the ring exerting an axial force.
  • the monobloc ring has elastic parts intended to come into engagement behind a shoulder of the body or of a sleeve which is integral therewith so as to retain the ring in translation and carries elastic tabs of a single piece with it, the free end of which constitutes a tooth intended to engage in the internal circumferential toothing of the ring.
  • the legs can be parallel to the axis or tangential.
  • the electrical connector shown in Figure 1 is a plug intended to be coupled to a base not shown, whose internal construction is indifferent, but which comprises an external body provided with a thread.
  • the connector has an insulating body 10 in which are provided electrical contact receiving passages 12, which are sockets in the illustrated case. These electrical contacts are retained by any means. In the illustrated case, they are retained by split rings 14 provided with locking fingers, held in place by a glued plate 16.
  • a grommet 18 of sufficiently deformable material to ensure sealing can be provided at the rear of the plate 16.
  • the body, the plate and the grommet are contained in a sleeve 20 against which bears a bulge in the body.
  • a locking ring 22 is mounted on the sleeve 20. This ring is threaded over a fraction of its length so that it can be screwed onto the thread of the complementary connector.
  • the locking ring 22 is free to rotate on the sleeve 20, but it is retained in the axial direction.
  • the ring 22 has a shoulder provided to bear against a circumferential step 24 of the sleeve.
  • notches 26 intended receiving pins 28 belonging to a washer 30, so as to constitute a sliding keying.
  • the washer 30 is notched so as to have, on its rear surface in the radial direction, a toothing of which each tooth has an edge separating a face of slight slope from a face of steep slope with respect to the circumferential direction.
  • the sliding keying secures in rotation the locking ring 22 of the washer 30 and therefore of the teeth.
  • the notched washer 30 is pushed backwards by elastic means, constituted, in FIGS. 1 and 2, by a corrugated washer 32, made of metal while the notched washer can be made of synthetic material.
  • the corrugated washer 32 applies the notched washer 30 against latching means, constituted by a ring 34 immobilized in rotation and in translation relative to the sleeve 20 carrying teeth regularly distributed facing the notched washer. It is immobilized in translation by engagement of elastic locking fingers 36, in one piece with the rest of the ring 34, in notches or a circumferential groove 38, of asymmetrical section, of the sleeve 20. It is immobilized in rotation relative to the sleeve, and therefore relative to the body 10, by a sliding keying consisting of radial projections 40 of the sleeve and corresponding grooves 42 of the ring 34.
  • the toothing is directed radially and no longer axially and the ring 34 provides all of the snap-in functions, i.e. includes the teeth engaging in the teeth and the elastic means applying these teeth in engagement.
  • Figures 4 and 5 show the internal teeth molded on the locking ring 22.
  • the ring 34 ( Figures 4 and 6) has internal projections 44 intended to engage in grooves of the sleeve so as to constitute a keying sliding. It is retained longitudinally in abutment against a shoulder of the sleeve by a split elastic ring or circlip, generally metallic.
  • the teeth of the ring 34 are formed by the end portion of elastic tabs 48, in one piece with the rest of the ring, which can flex elastically.
  • the teeth like the internal teeth formed directly on the locking ring 32, have an asymmetrical profile, as shown in FIGS. 5 and 6.
  • Figures 7 and 8 show an alternative embodiment of the ring 34, which has hooking fingers on the sleeve, making the split ring 46 unnecessary.
  • the tabs 48 shown in Figures 7 and 8, unlike those of the mode embodiment of Figures 4 and 6, are directed in the circumferential direction.
  • the ring 34 also includes keying projections 44 intended to engage in grooves of the sleeve.
