Definitions

  • the present invention relates to a device for Hermaphroditic locking for a connector.
  • This locking device can be put in work for all types of connectors, and in particular for electrical connectors and connectors optical fiber.
  • the two connector elements are by identical definitions and respectively contain complementary means adapted to cooperate for secure the two connector elements.
  • Locking is thus ensured by a system with helical ramps based on the cam principle linear, allowing to bring together the two elements of connectors when connected by a movement of rotation.
  • each of them has a needle adapted to penetrate a bore additional provided on the other connector element.
  • a locking nut is provided in some realizations.
  • the object of the present invention is to resolve these disadvantages and to propose a device for simplified design locking, allowing to ensure a precise connection of the elements of connectors while implementing a minimum of rooms.
  • the locking device of two elements of connectors covered by the invention comprises two rings identical locks forming a sleeve around respectively of a connector element.
  • each ring of lock includes a guide groove and a suitable lug to come into engagement in a connecting end of the other guide groove locking ring, spring means being adapted to exert a spreading force on both locking rings.
  • connection is made very simple, by a hooking lug engaged in a groove end.
  • This link is reinforced thanks to the means forming a spring which, while exerting a tending force to move aside the locking rings, allow advantageously, to strengthen the attachment of the tab in the groove.
  • the attachment of the hanging tab in the end of the groove, at the end of its stroke in the guide groove ensures in a at the same time the correct positioning and indexing in rotation of the two connector elements during their connection.
  • the guide groove extends along an arc of the sleeve formed by the ring locking and is made in the thickness of a wall of the sleeve, the hooking lug being formed in one end of the locking ring extending beyond said wall.
  • the wall of the locking ring supports and guides the hooking tab of the other ring when it circulates in the guide groove.
  • the attachment of the hanging tab in the end of the guide groove is made to the right of this wall, which avoids any sliding of the latch in one direction radial of the sleeve forming the locking ring.
  • the locking device allows to realize connecting two parts of a connector, such as a electrical or fiber optic connector.
  • connection, inside the connector, of the cables is well known in the art and does not will not be described in detail below.
  • the locking ring 10 forms a sleeve 13 around the connector element and is floating by compared to this one.
  • the locking ring is held in place by example by means of a nut mounted on a thread 1.
  • the locking ring has a groove 12 and a connecting end 14 adapted to come into engagement with a lug 21 for a second ring locking (see Figure 4 for example).
  • the locking ring also has a hanging tab 11.
  • the groove 12 extends along an arc of a circle, in a plane transverse to the sleeve 13, and is located in look of a wall 15 of the locking ring.
  • the groove 12 thus formed in the thickness of the wall 15 of the sleeve 13 thus forms a ramp of guide on which the leg can move hooking 21 of the other locking ring 20.
  • This groove 12 can be produced by milling of the external face of the wall 15.
  • the locking ring 10 further comprises one end extending beyond the wall 15 of the muff. This ring end is suitable to come fit onto the wall 25 of the other ring lock 20 when connecting.
  • This sleeve end 13 has the tab hanging 11.
  • the latter is formed by a wing, by example in the shape of an "L" extending from an arm 11a extending along the longitudinal axis ⁇ of the sleeve 13.
  • the leg of the "L” is secured to the arm 11a and extends in an arc centered on the longitudinal axis ⁇ of the sleeve 13 and the foot of the "L” extends parallel to the longitudinal axis ⁇ of the sleeve 13 and thus forms a lug directed towards the sleeve 13.
  • the groove 12 has, at its opposite end at the connecting end 14, an opening opening in the end of the sleeve 13 and adapted to the introduction of the hooking lug 21 integral with the arm 21a of the other locking ring 20.
  • the guide groove 12 is demarcated, at its end opposite the end of connection 14, by the arm 11a secured to the tab hanging 11.
  • the connecting end 14 of the groove of guide 12 has a shoulder forming a stop 14a adapted to engage with the lug along a transverse plane of the guide groove 12.
  • this stop 14a avoids any rotation relative to the locking rings 10, 20, when these are in engagement.
  • the connecting end 14 of the groove of guide has an "L" shape identical to that of the tab attachment 11, the stop 14a consisting of the foot of the "L" shape.
  • the stop 14a forms in the guide groove 12 a narrowed cross section of reduced width but sufficient for the passage of the hooking lug 21, and at least equal to the length of the foot of the shape in "L" of the hooking lug 21.
  • Spring means 2 illustrated in Figure 5, are further adapted to exert a force spacing on the two locking rings 10, 20.
  • These spring means 2 can by way of example consist of a coil spring maintained in compression between the two walls 10a, 20a opposite ends of the locking rings 10, 20 when the connection is made.
  • Each attachment tab 11 is not aligned, in the longitudinal direction ⁇ of the sleeve 13, with the connecting end 14 of the groove 12, but at otherwise noticeably offset.
  • the attachment tab 11 is located upstream of the connecting end 14, relative to the direction of rotation F of the locking ring 10 during locking the device.
  • the lug 11 can thus penetrate in the guide groove 22 of the other ring of locking 20, escaping from the connection end 24 of this groove 22.
  • connection points of the rings locking 10, 20, respectively formed by the tab attachment 11 and the connecting end 24, and the hooking lug 21 and the connection end 14 are offset around the peripheral periphery of the sleeves 13, 23, so that these connection points do not are not aligned along an axis parallel to the axis longitudinal of the locking rings 10, 20.
  • This arrangement makes it possible to have points of link distributed around the periphery of the locking.
  • the locking ring 10 has two guide grooves 12 and two tabs hanging 11.
  • the guide grooves 12 are arranged symmetrically with respect to the longitudinal axis ⁇ of the locking ring 10.
  • attachment tabs 11 are arranged symmetrically with respect to the axis longitudinal ⁇ of the locking ring 10.
  • This arrangement makes it possible to obtain points of fixing distributed symmetrically with respect to the axis longitudinal ⁇ of sleeves 13, 23.
  • the second locking ring 20 is in all identical point to the locking ring 10 described above with which it is intended to cooperate when locking.
  • It includes a sleeve 23 and has two guide grooves 22, each having one end of link 24, and a lug 21.
  • each hooking lug 11, 21 is introduced respectively in the guide groove 22, 12 of the other ring locking.
  • each latch 11, 21 flows in the guide groove 22, 12 and passes beyond the stop 24a, 14a of the connecting end 24, 14.
  • the user To disassemble the connector, to modify or repair the wiring, the user must bring the two locking rings by exerting a force opposite to the restoring force developed by the means forming spring 2 and rotate the two rings of locking in opposite directions to the direction of rotation F and G.
  • each locking ring may not have only one guide groove and one tab hanging. These can then be arranged symmetrically about the longitudinal axis of the locking ring.
