Definitions

  • the present invention relates to a connector locking lever.
  • the present invention relates in particular, although not limited to, a locking lever for the rapid connection and disconnection of electronic boxes in an aircraft, the electronic boxes being used for example for video and / or audio applications .
  • contact elements of a first plug-in part which is in the form of a cable harness plug, are removably coupled to contact elements opposite one another.
  • plugging part which is in the form of a plug contained in an electronic box.
  • connection or disconnection operations of such interlocking elements can be difficult to perform when the mechanical stresses during connection are important.
  • a poor connection may result in false contacts or even damage to the contact elements.
  • the electronic boxes are arranged under the seats of an aircraft. This has the disadvantage that the passenger, sitting on the seat, can act on the electronic box.
  • the first and second plugging portions may move relative to each other, which may cause disconnection of the electronic unit. Such a connection therefore poses problems of reliability and security.
  • the object of the present invention is to propose a locking lever for a connector which avoids at least some of the aforementioned drawbacks, which allows connection and disconnection. simpler two plugging parts, and that keeps the two plugging parts in the connected position.
  • the subject of the invention is a locking lever for a connector, said connector comprising a first plug-in part, fixed, and a second plug-in part capable of being connected to said first plug-in part by a translation in a connection direction, said locking lever having two end portions adapted to be pivotally attached, along an axis substantially perpendicular to said connection direction, on two opposite faces of said first plug-in portion, each of said end portions comprises a cam path, said locking lever being pivotable between a release position, in which an open end of each of said cam paths is adapted to be positioned at a lug of said second portion; plugging, and a locking position in which each of said pins is adapted to be positioned in a portion of the lock age of said cam path characterized in that said end portion being resiliently deformable to allow said pin to penetrate said locking portion and exert a compressive force between said first plug portion and said second portion of said cam portion; plugging.
  • each of said end portions comprises a groove extending along a portion of said corresponding cam path, one end of said groove opening at an end of said cam path, so as to that said cam path defines with said groove a tongue adapted to be deformed elastically to allow deformation of said portion terminal in response to a pressing force exerted on said tongue of said cam path.
  • said tongue is able to elastically assume a stable position once said pin has positioned in said notch to maintain the connection force.
  • said second plugging part is connected to an electronic box, said first plugging part being connected to an electronic device integrated in a vehicle, said first plugging part being fixed to said vehicle .
  • the locking lever comprises two lateral branches interconnected by a transverse spacer, said lateral branches being able to extend along two opposite faces of said electronic unit when said locking lever is in said locking position.
  • said spacer is able to extend substantially parallel to a face of said electronic housing when said locking lever is in said locking position, at least a handle portion of said spacer being offset from said face of said housing.
  • said vehicle is an aircraft, said electronic box being disposed under the seat of a seat of said aircraft, so that, when said locking lever is in said locking position, said lever locking is substantially parallel to the plane of said seat, said seat being able to press on said locking lever to maintain said locking lever in said locking position.
  • a connector 1 having a first plugging portion 2 and a second plugging portion 3, intended to be assembled to one another by interlocking.
  • the first one Part 2 is connected to an electronic device (not shown), for example integrated in a structure of an aircraft, the first part 2 being fixed relative to the structure.
  • the second part 3 is connected to an electronic box 4.
  • the electronic box is intended to be disposed under the seat of a seat (not shown) of the aircraft.
  • the second part 3 can be connected to the first part 2 by a translation in an X connection direction.
  • the second part 3 comprises for example, as contact elements (not shown), a multiplicity of plug sockets arranged in line.
  • the plug sockets are intended to surround, in the connected position, opposite contact elements (not shown) of the first part 2, for example pins.
  • Such a connector is known per se.
  • the connector 1 comprises a U-shaped locking lever 5.
  • the lever 5 comprises two substantially identical lateral branches 6, connected together by a transverse spacer 8.
  • the lateral branches 6 extend parallel to each other.
  • the free ends 9 of the branches 6 are pivotally attached to pivot elements 11 arranged on two opposite lateral faces 12 of the first part 2.
  • the locking lever 5 can thus pivot with respect to the first part 2 around a Y axis substantially orthogonal to the X axis, between a rest position ( figure 1 ) and a locking position ( figure 8 ).
  • the spacer 8 has a central portion 13 serving as a handle during the manipulation of the lever 5, as will be described in detail below.
  • Each branch 6 has, starting from the spacer 8, a rectilinear central portion 16 arranged to form a right angle with the corresponding end portion 15. At the free end 9, each branch 6 has an end portion 17.
  • Each end portion 17 is substantially planar and disposed in the same plane as the middle portion 16.
  • Each end portion 17 has a groove 18 defining a cam path, the curvature of the cam path 18 being directed so that the cam path 18 is wound around the pivot 11.
  • the distance of the cam path 18 to the pivot 11 decreases from its end 19 towards the opposite end 24 of the cam path 18.
  • a groove 21 extends along a portion 22 of the cam path 18, one end 23 of the groove 21 opening at the end 24.
  • the cam path 18 defines with the groove 21 a tongue 25 adapted to be elastically deformed in response to a pressing force exerted on the tab 25 of the cam path 18, as will be described in detail below.
  • the second part 3 comprises, on each of two opposite lateral faces 30 corresponding to the faces 12, a lug 31 adapted to engage in the cam path 18.
  • the lugs 31 are arranged so that, when the second portion 3 is in position. abutting against the first part 2, each lug 31 is at one of the openings 20.
  • the tongue 25 In the vicinity of the end 24, the tongue 25 has a rounded notch which defines a recess 32 adapted to receive the pin 31 in the locking position of the lever 5.
  • each pin 31 slides in the corresponding cam path 18, towards the end 24.
  • the second part 3 under the effect of the cam tracks 18 acting on the pins 31, engages in the first part 2.
  • the tongue 25 begins to deform by elasticity, due to the pressing force exerted by the lug 31 on the tongue 25.
  • the tongue 25 assumes a stable position by elasticity, which causes the creation of a hard point 33 to maintain the lug 31 in the recess 32 and exert a force of compression between parts 2 and 3. This allows in particular to compensate for the tolerance intervals of the coupling. In this position, the contact elements of the first and second parts 2 and 3 are correctly connected.
  • the central portion 13 of the spacer 8 extends parallel to the upper face 34 of the housing 4, substantially parallel to the axis Y.
  • End portions 15 of the spacer 8 are extend along the opposite side faces 35 of the housing, substantially perpendicular to the axis X.
  • the branches 6 extend along the side faces 35, substantially parallel to the axis X. The volume occupied by the lever 5 in rest position is thus minimized, the parts of the lever 5 having a small thickness and extending along the housing 4, as is visible on the figure 8 .
  • the lever 5, when in the locked position, is substantially parallel to the casing 4. This allows the casing 4 to be placed under the seat of a seat of the aircraft substantially parallel to the plane of the seat. sitting, that is to say horizontally.
  • the support of the seat on the lever 5 helps maintain the lever 5 in its horizontal position, that is to say in its locking position, which prevents inadvertent disconnection of the housing 4.
  • a passenger can not access the housing 4, the latter being disposed under the seat of his seat.
  • the cam paths 18 of the lever 5 thus make it possible to ensure good distribution of the forces during the connection and disconnection operations, which facilitates these operations for the user.
  • the lever also makes it possible to define the insertion depth and to ensure the guidance along the X axis of the second part 3 with respect to the first part 2, which avoids twisting or breaking contact elements.
