Definitions

  • the present invention relates to a device for protecting the nestable elements of a connector.
  • the plug when a plug is used to protect a connector member, the plug must be removed when using the connector member for connection to another connector member. There is the risk that the user forgets or omits, for lack of time, to put the cap back in place.
  • the plug may be mislaid or, if attached to the connector element, it may receive mud or fall into the mud, so that it can no longer be closed. connector element with the plug.
  • the sludge may accumulate in the interstices between the connecting members and the piston so that it quickly becomes impossible to maneuver the piston and thus to disengage connecting members.
  • An object of the invention is to provide an easily manipulable protection device and providing effective protection.
  • a device for protecting a connector comprising two interlocking connector elements
  • the protection device comprising, for at least one connector element to be protected, an elastic tubular sleeve. having an end configured to be attached to a connector member by sealingly surrounding the connector member and having a length sufficient to extend at rest cantilevered beyond an end of the connector member which carries the elastic sleeve, the cantilevered end including means for flattening the sleeve and resiliently holding corresponding lips against each other.
  • the elastic tubular sleeve remains permanently attached to the connector element that it protects and therefore does not risk being lost, and its opening is performed at the time of engagement with another connector element so that the risk of sludge penetration inside the protective sleeve is minimized.
  • the means for flattening the sleeve comprise at least one spring blade extending perpendicularly to a longitudinal direction of the elastic sleeve and embedded in a wall section adjacent to the end held flattened.
  • the spring blade comprises a bending around an axis parallel to the spring blade, the bending having a concavity turned to the corresponding lip.
  • the holding force of the lips against each other is further increased.
  • each leaf spring has a decreasing width from a central zone of the blade towards the ends thereof.
  • the protection device is intended to protect a connector comprising two interlocking connector elements 1 and 2.
  • the connector element 1 comprises a base 3 intended to be fixed to a wall of the connector. a device not shown.
  • a cylindrical sleeve of circular section 4 is fixed to the base 3 and contains a connection member 5 comprising metallized holes 6 connected to connecting son.
  • the connector element 2 comprises a cylindrical sleeve of circular section 7 intended to be mounted at the end of a cable and containing a connection member 8 equipped with pins 9 in register with the metallized holes 6.
  • the connector element 1 is equipped with an elastic tubular sleeve 10, for example a rubber sleeve.
  • the sleeve 10 has four folds accordion 11 whose inner diameter is preferably equal to or slightly greater than the diameter of the sleeve 4, to allow easy sliding of the folds accordion 11 on the sleeve 4. Only the extreme wall of the last fold accordion has a suitable diameter to allow a press fit on the sleeve 4 and ensure a hold in place of the sleeve 10 on the sleeve 4.
  • the elastic sleeve 10 comprises two beads 13 whose inner edge delimits lips 14 which are biased towards each other by leaf springs 15 embedded in the rubber forming the beads 13
  • the lips are rectilinear and form a slot 16 sealingly closed by the forces applied by the leaf springs 15.
  • the leaf springs 15 are subjected to a prestress obtained in this first embodiment by providing a thickness E (see figure 1 ) of decreasing material between a spring blade 15 and the corresponding lip 14 from the central zone of the spring blade towards its ends.
  • the spring blades 15 are thus bent around an axis corresponding to the longitudinal axis of the sleeve 10.
  • the beads 13 further comprise clipping lugs 17 which extend cantilevered beyond the beads 13 and whose 'utility will be seen further.
  • the wall portion 18 of the elastic sleeve which connects the beads 13 to the first accordion fold 11 takes a pseudo conical shape as illustrated by the figures 1 and 6 .
  • the leaf springs 15 bend more strongly around the longitudinal axis of the elastic sleeve 10 and the lips 14 separate by taking an increasingly pronounced curve until a total opening of the sleeve as illustrated by the figure 2 .
  • the opening may also be obtained by exerting a spreading force on the inner wall of the sleeve portion 18 as will be seen later.
  • the lips 14 are preferably semicircular in order to fit the contour of the sleeve 4 of the connector element 1.
  • the leaf springs preferably have a decreasing width from the central part of the blades 15 towards their ends in a sinusoidal law so as to obtain a constant restoring force for all the points of the lips 14.
  • the beads 13 preferably comprises flats 19 perpendicular to slot 16. The flats fold over themselves (see figure 4 ) when opening the sleeve.
  • the elastic sleeve 20 ensuring the protection of the connector element 2 has a structure identical to that of the sleeve 10, with the exception of clipping lugs 17 which are replaced by clipping cavities 21.
  • the same Numerical references will be given for the parts, identical to the dimensions, the accordion folds 11 of the sleeve 20 having a diameter adapted to the external diameter of the sleeve 7 of the connector element 2.
  • the sleeves 10 and 20 are sealed.
  • the slots 16 of each of the sleeves 10, 20 are presented facing each other so that the clipping lugs 17 of the sleeve 10 are facing the cavities clipping 21 of the sleeve 20.
  • An approximation movement of the connector elements thus causes clipping of the beads 13 so that they are subsequently secured to one another and thus deform identically.
  • a movement of approximation of the elements of connector 1 and 2 then causes support of the end of the sockets 4 and 7 on the corresponding inner face of the sleeve portions 18.
  • the wall portions 18 open gradually and cause the lips 14 to move apart until the moment when the passage is sufficient to allow the interlocking of the connecting members 5 and 8 as illustrated by the figure 8 . In this movement, the accordion folds crush gradually as illustrated by the Figures 6 to 8 .
  • the sleeve portions 18 have a sufficient rigidity for the connection force causes them to slide on the sleeves 4, 7 without bending.
  • the inner surfaces of the sleeve portions 18 and the outer surfaces of the sleeves 4, 7 have coefficients of friction promoting their relative sliding.
  • the clipping of the elastic sleeves 10 and 20 not only allows a concomitant opening of the lips 14 but it also makes it possible to pull each sleeve on the corresponding connector element during the separation of the connector elements, which guarantees a return resilient sleeves in the closed position when separating the connector members.
  • the connector elements 1 and 2 are identical to those of the previous figures and therefore have the same reference numerals.
  • the protective sleeves 30 and 40 of the second embodiment do not include accordion pleats allowing retraction of the sleeves as the approximation of the connector elements.
  • the sleeve 40 surrounding the connector element 2 is a cylindrical sleeve having a wall of constant thickness with the exception of a chamfer 41 turned outward at the end turned towards the corresponding end of the protective sleeve 30.
  • the sleeve 30 also has a cylindrical wall in the open position but also has an internal shoulder 31 for the penetration of the sleeve 40 into the sleeve 30 during the engagement of the connector elements 1 and 2.
  • the sleeve 30 further comprises at its end facing the sleeve 40 a chamfer 32 facing inwards.
  • the protective sleeve 30 comprises leaf springs 33 which extend perpendicularly to the longitudinal direction of the elastic sleeves. In this embodiment, however, the leaf springs 33 are, at rest, rectilinear in a plane parallel to the lips 14 and are bent around an axis parallel to the spring blade, the bending having a concavity turned towards the corresponding lip 14. In order to obtain a regular circular shape of the lips 14 when opening the sleeves, the leaf springs 33 preferably have a top view similar to the leaf springs 15 of the first embodiment.
  • the springs 15 and 33 have been illustrated as two separate springs, they may be in the form of a ring in one piece or be joined by hinges at their ends.
  • the sleeves according to the invention can also be made without leaf springs by providing a flattened shaping during the production of the sleeves so that they are automatically returned to the rest position.
  • the folds accordion have been illustrated with identical inner and outer diameters, so that the shrinkage of the sleeves is by crushing folds, it can provide accordion pleats according to frustoconical shapes so that the folds fit into each other during retraction.
  • the number of folds can be different from four.
  • PTFE polytetrafluoroethylene
  • sleeve portions 18 it is possible to provide, in particular on the sleeve portions 18, localized stiffening elements (ribs, local reinforcements, whether or not referred to as material veneers, a mesh or a network of ribs, etc.) to promote the deformation. sleeve portions 18 in a given direction (opening during connection). Conversely, zones of preferential deformation (such as areas of smaller thickness or non-through slots) may be provided for the same purpose.
  • ribs, local reinforcements whether or not referred to as material veneers, a mesh or a network of ribs, etc.
