Definitions

  • the present invention relates to an electrical connector for connecting electrical cables.
  • Such a connector finds application in particular to the conveyance of rapid information signals as is the case for example for command and control devices used in aircraft.
  • An electrical connector is known of the type comprising a base, a plug and a latch mounted on the plug body to secure the plug to the base by screwing.
  • Connecting means between the plug body and the latch are provided to brake the rotation in one direction and in the other of the latch relative to the plug body.
  • These connecting means are particularly intended to prevent the loosening of the lock of the base body during external vibrations transmitted to the electrical connector.
  • the connecting means are constituted by grooves arranged on the circumference of an annular portion of the plug body extending parallel to the longitudinal axis of this body and by a number of elastic metal blades fixed angularly equidistant from an internal cylindrical wall of the lock and each comprising a boss snapping into the spaces between adjacent grooves.
  • the present invention aims to eliminate the above drawbacks by proposing an electrical connector of the type comprising a base, a plug, a latch mounted on the plug body to secure the plug to the base by screwing and means of connection between the plug body and the latch braking the rotation in both directions of the latch relative to the plug body and characterized in that the connecting means are arranged so as to brake the rotation of the latch in the direction of unscrewing it ci following a force greater than the braking force of the lock in the direction of screwing of the latter.
  • connection means comprise first and second coaxial wheels, the side faces of which face each other have teeth, each with flanks in gentle and steep slopes respectively, held in mesh with each other by the return force of an elastic member, the second wheel being integral with the body of the lock while the first wheel is immobilized in rotation relative to the plug body and can move axially relative to the latter against the force of return of the elastic member, so that the rotation of the bolt in the direction of screwing causes the flanks with a gentle slope of the teeth of the second wheel to slide over the flanks with gentle slope corresponding to the teeth of the first wheel and the rotation of the bolt in the unscrewing direction brings the steep sides of the teeth of the second wheel into abutment against the corresponding steep sides of the teeth of the first wheel.
  • the plug body comprises at least one lug integral with the latter engaged in an internal groove of conjugate shape of the first wheel.
  • two diametrically opposite lugs are secured to the plug body and respectively engaged in two internal grooves of the first wheel.
  • the second wheel is secured to the body of the lock by screwing it into the body of the lock.
  • the elastic return member consists of a corrugated ring interposed between the lateral face of the first wheel opposite its toothed face and an internal annular wall of the lock.
  • the plug body comprises a flange bearing against the lateral face of the internal annular wall opposite to that serving as a support for the elastic return member.
  • the internal annular wall of the lock comprises two grooves for the passage of the two lugs respectively between the first wheel and the annular wall, the two lugs then being respectively housed in the two grooves of the first wheel by rotation of the plug body relative to the lock.
  • the lock comprises an internal thread made on the side of the lateral face of the internal annular wall of the lock on which the flange is supported and cooperating with an external thread of the body of the base.
  • the two toothed wheels are made of hard steel.
  • the electrical connector comprises a base 1 intended to be fixed to an appropriate fixed support, a plug 2 and a latch 3 mounted on the body 4 of the plug 2 to secure the latter to the base 1.
  • the body 5 of the latch 3 is in the form of a sleeve having an internal thread 6 machined on a determined inlet portion of the internal cylindrical wall of the sleeve.
  • the sleeve 5 also comprises an internal annular wall 7 separated from the internal thread 6 and comprising two diametrically opposite grooves 8 passing through the wall 7.
  • An internal thread 9 is also machined on an outlet portion of the internal cylindrical wall of the sleeve 5 and defines with the annular wall 7 an annular housing cavity 10.
  • the sleeve 5 comprises on its outer periphery a number of sectors in relief ridged 11 angularly and regularly spaced from each other other and intended to facilitate manual operation of the lock 3 during the screwing or unscrewing operations thereof. These striated sectors 11 define between them spaces 12 allowing a claw wrench to tighten the lock 3 energetically to the base 1 or to loosen it.
  • the body 13 of the base 1 comprises a fixing plate 14, a tubular portion 15 integral with one face of the plate 14 and a tubular endpiece 16 integral with the opposite face of the plate 14 and arranged coaxially with the tubular portion 15 so as to define together an internal cylinder passage.
  • the portion 15 comprises an external thread 17 similar to the internal thread 6 of the lock 3 while the end piece 16 also includes an external thread 18 intended to cooperate with a threaded ring (not shown) for fixing a connection cable electric at the nozzle 16.
  • the plug 2 has its generally cylindrical body 4 in which is fixed an insert 20 of an electrically insulating material comprising channels 21 inside which are housed male or female pins (not shown) of the connector.
  • the body 4 comprises a flange 22 located near the transverse median plane of the body.
  • the cylinder portion of the body 4 to left of the flange 22 comprises from right to left two diametrically opposite lugs 24 and an external thread 25 whose nominal diameter is less than the diameter of the opening defined by the annular wall 7.
  • the thread 25 cooperates with a fixing ring (not shown ) an electrical connection cable to the plug body 4.
  • the body 4 of the plug and the body 5 of the lock 3 are interconnected by connecting means which are arranged so as to slow the rotation of the lock 3 relative to the plug 2 in the direction of unscrewing with a force greater than the braking force of the lock 3 in the direction of screwing of the latter.
  • These connecting means comprise a first crown-shaped wheel 26 having an outer diameter less than the diameter of the annular cavity 10, an elastic member 27, constituted in this case by a corrugated metal washer with an outer diameter less than the diameter of the cavity 10, and intended to exert a restoring force on the wheel 26 against an annular lateral face of a second wheel in the form of a crown 28 with external thread 29 intended to cooperate with the internal thread 9 in the same way.
  • the wheel 26 and the member 27 are thus housed in the cavity 10.
  • the elastic member 27 is interposed between the annular wall 7 and a corresponding side face of the wheel 26, the opposite side face of which comprises, cut therein. , teeth 26a meshing in identical teeth 28a cut in the lateral face opposite the second wheel 28.
  • the teeth 26a and 28a are cut so as to have flanks with a steep or steep slope respectively 26a1 and 28a1 and opposite sides with gentle slopes respectively 26a2 and 28a2.
  • the first wheel 26 has two diametrically opposite through internal grooves 26b in which the two lugs 24 engage respectively. integral with the plug body 2.
  • the wheels 26 and 28 and the elastic member 27 are coaxial with the longitudinal axis of the body 13 of the base 1 and the flange 22 bears against the corresponding annular face of the wall 7 opposite to that retaining the elastic member 27.
  • the wheels 26, 28 and the elastic member 27 each have an internal diameter greater than the nominal diameter of the thread 25.
  • the assembly of the body 4 of the plug 2 to the body 5 of the bolt is carried out by introducing the body 4 axially into the bolt 3 so that the threaded part 25 passes through the annular wall 7, the elastic member 27 and the wheels 26, 28 and then engaging the two pins 24 respectively through the two grooves 8 of the wall 7 which are then in the portion of space left free by the elastic member 27 between the first wheel 26 and the wall 7.
  • the plug body 4 By turning the plug body 4 relative to the body 5 of the lock 3, the two lugs 24 are housed respectively in the two grooves 26b of the first wheel 26. Then, we screws the bolt 3 and the bolt 3 to the base 1 by the threads 9 and 17.
  • the rotation of the lock 3 in the opposite direction to the arrow F is accompanied by a rotation in the same direction of the wheel 28 relative to the wheel 26 but this rotation is stopped by the steep flanks of the teeth 28a of the wheel 28 abutting against the corresponding steep flanks of the teeth 26a of the wheel 26. Only a relatively large force applied to the wheel 28 allows the teeth 28a to jump over the teeth 26a and this against the return force of the elastic member 27. In this way, the lock 3 is blocked in the direction of unscrewing sufficiently effective to withstand the forces resulting from external vibrations tending to loosen the lock 3.
