Definitions

  • the invention relates generally to electrical outlets.
  • This closed position of the cover makes it possible to protect the well, and more particularly its cells, from dust or water, for example when such an outlet is located outside.
  • the invention aims to simplify the manufacture of the socket by providing locking / unlocking means integrated into the overall size of the socket.
  • the socket 1 comprises, in a manner known per se, a socket body and a cover 2.
  • the body comprises a housing 3 and a hubcap 4 which closes the housing 3.
  • the lid 2 is rotatably mounted on the hubcap 4 along one of the edges thereof.
  • the housing 3, the hubcap 4 and the lid 2 are made of molded plastic.
  • the housing 3 is substantially parallelepipedal and has a bottom wall, a side wall 5 and an opening opposite to the bottom wall. On its side wall 5, the housing has two opposite rectangular cutouts extending over almost the entire height of the side wall 5. Each cut is filled by a wafer 6 of plastic material having in its center a location for cable connection.
  • the housing 3 is adapted to receive a pickup motor (not shown as a whole).
  • a pickup motor (not shown as a whole).
  • Such a motor known per se, comprises two contact parts of the female or cell type. Each cell is adapted to receive one of the pins of a complementary power plug.
  • the motor further includes a grounding pin 7 ( figure 1 ) protruding from the hubcap 4.
  • the hubcap 4, which covers the opening of the housing 3, is substantially square and has a much lower height than that of the housing 3.
  • the hubcap 4, described in more detail in the following, has in particular at its center a well 8 for receiving a power plug.
  • the lid 2 is pivotally movable relative to the hubcap 4 between an open position ( figure 1 ) in which the well 8 is accessible to the power plug and a closed position ( figure 2 ) in which the cover 2 covers the well 8.
  • a spring 10 ( figure 6 ) urges the cover 2 towards its open position.
  • the opening of the lid 2 from its closed position is controlled by pressing a key 9 that includes the lid 2.
  • this key 9 When this key 9 is pressed, it leaves its rest position ( figure 2 ) which unlocks the lid which is then pivoted.
  • the key 9 remains in the support position ( figure 3 ) then, in a second step, the lid 2 having pivoted sufficiently, the key 9 resumes its rest position and the lid 2 pivots to reach its open position.
  • This has a main wall 12 of generally square shape.
  • This wall 12 has four flanges oriented towards the hubcap 4 when the lid 2 is in the closed position.
  • the hubcap 4 has recesses inwards. These withdrawals are adapted to allow the positioning of the bottom edge 13 between two bosses that includes the hubcap 4.
  • the flange 13 has a stud 18 while at the other end the flange 13 has a cylindrical open housing adapted to receive the spring 10.
  • the cover 2 Opposite the bottom edge 13, on the side of the front rim 15, the cover 2 has a shallow cutout but wide and centered to accommodate the key 9.
  • the rim 15 is therefore limited to two end portions on either side of this cut.
  • the space for accommodating the key 9 is delimited towards the bottom by a flexible wall 21 which extends parallel to the rim 13 and disposed slightly away from the plane in which the flange 15 extends.
  • Each bridge 22 has a cylindrical and blind orifice 23, the opening of the orifice 23 being located opposite the other orifice 23.
  • the surface of the cover 2 intended to face the hubcap 4 comprises a circular rib 25 and projecting in the center of this surface.
  • the key 9 comprises two walls 26, 27 at right angles: a contact wall 26 flat and generally rectangular and a support wall 27 having the shape of a half-disk.
  • the wall 27 has a central zone 28 slightly concave and having at its center several support pads 29 forming a rough zone having a slight relief with respect to the general surface of the zone 28.
  • the key 9 further comprises four parallel reinforcing ribs 30 which extend transversely to the wall 26 and to the wall 27 and improve the overall rigidity of the key 9.
  • the two reinforcing ribs 30 located on the lateral ends of the key 9 each comprise a positioning pin 31 adapted to be positioned in one of the orifices 23 of the cover 2.
  • Each positioning pin 31 has a ramp on its portion facing the wall 27 to allow the snap of the key 9 on the cover 2.
  • This rib 32 is located near the end of the wall 26 opposite the wall 27.
  • the key 9 has two tabs 33, each tab extending apart from each other and each near a stud 31.
  • each leg 33 has a limited height but sufficient to accommodate at their free end and the side opposite the rib 32 a notch 34 so that each leg 33 forms a latch.
  • Each notch 34 has a flat surface 35 parallel to and facing the wall 27 so that this surface 35 forms with the adjoining surface of the remainder of the tab 33 a shoulder.
  • the notch 34 has a ramp surface 36 oriented obliquely to the surface 35 so that the thickness of the notch 34 (in a direction of notch 34 to wall 27) decreases towards the free end of the notch 34.
  • the notches 34 extend over almost the entire width of the tabs 33 with the exception of an extreme zone located on the side of the studs 31.
  • Each tab 33 has a beveled edge located between a stud 31 and the notch 34.
  • Each tab 33 thus has a ramp 37 oriented transversely to the wall 27 so that the tab 33 is wider on the side of the notch 34.
  • the hubcap 4 has a wall 40 which closes the housing 3 and is placed above the motor of the socket.
  • the wall 40 has at its center the well 8 which is intended to receive a current plug.
  • the well 8 is cylindrical and has a bottom wall having two orifices superimposed on the cells of the engine and a third orifice through which the spindle 7 passes.
  • the wall 40 is substantially flat around the well 8, the latter projecting slightly outwardly by a circular rib 41 projecting.
  • a circular rib 41 projecting around this rib 41 is placed an annular seal 42 made of plastic material.
  • the outer diameter of the annular seal 42 corresponds to the inside diameter of the rib 25 of the lid 2 so that when the lid 2 is in the closed position, the rib 25 comes against the seal 42 so as to close the well 8 tightly.
  • the hubcap 4 has at two of its consecutive corners bosses 45 whose shape is adapted to the withdrawal that the lid 2 has.
  • Each boss 45 has an opening opening on a bore.
  • One of these bores allows the insertion of the stud 18 and the other of these bores allows the positioning of the spring 10 so that the lid 2 is pivotally mounted on the hubcap 4 with the spring 10 which urges the lid 2 towards its open position.
  • the front side wall 50 of the hubcap 4 (according to the representation of the figure 9 ), which wall is opposite the bosses 45, extends outwardly by a projecting rib 51 of very low height. This rib 51 also extends transversely to the bosses 45.
  • the wall portion 40 located between the annular seal 42 and the rib 51 has a relief 52 which has a rectilinear portion 53 against the rib 51, two lateral portions 54 which extend transversely to the portion 53 each between one end of the portion 53 and the seal 42 and finally a portion 55 in an arc which extends along the seal 42.
  • This relief 52 also has two fingers 56. Each finger 56 takes root on the portion 55 and extends towards the portion 53 parallel to the portions 54.
  • the fingers 56 and the portions 53, 54, 55 are here molded in one piece with the hubcap 40 so that the manufacture of the hubcap is particularly simple. More generally, the manufacture of locking / unlocking means is simple since a portion of the elements are molded in one piece with the hubcap and the other part is simply snapped to take place on the lid.
  • the locking / unlocking means are perfectly integrated into the socket whose size remains constant while offering the advantage of offering actuation quite intuitive to the user with a simple press of a key on the lid.
  • each finger 56 is disposed near the portion 53.
  • the height of the relief 52 corresponds to that of the circular rib 41 with the exception of the fingers 56 whose height is slightly greater.
  • the free end of each finger 56 has a notch 57 on the surface of the finger 56 opposite the portion 54 adjacent. Each notch 57 has a general direction transverse to the wall 40.
  • Each finger 56 has its root up to the notch 57 a constant thickness (taken in the general direction of the portion 53).
  • Each notch 57 has a plateau surface 58 so as to form a shoulder with the adjacent surface of the rest of the finger 56.
  • the surface 58 is slightly inclined with respect to the direction transverse to the wall 4 (FIG. figure 5 ).
  • the notch 57 has a ramp surface 59 oriented obliquely with respect to the surface 58 so that the thickness of the notch 57 (in a notch direction 57 towards the portion 53) decreases towards the free end of the screen 57.
  • the portion 53 has on the side facing the portion 55 two lugs 60 spaced from each other and separated by a distance that corresponds to the distance between the tabs 33 for a cooperation between the tabs 33 and the
  • the chins 60 project towards the circular rib 41.
  • Their surface facing the wall 40 extends transversely to the rest of the body. portion 53 so that under the lug 60 there is a shoulder.
  • Each lug 60 has on the side opposite to the shoulder at its free end a ramp 61 so that the thickness of the lug 60 (in the direction transverse to the wall 40) decreases to its free end.
  • the socket 1 thus comprises two latches each formed by a tab 33, a finger 56 and a latch 60.
  • the key 9 is in its rest position in which the contact wall 26 and the flexible wall 21 are arranged parallel to one another with the rib 32 which is in contact with the flexible wall 21.
  • the ramps 36, 61 in contact two by two, are oriented in the same plane so that they allow a ramp ramp slip of the tabs 33 on the lugs 60.
  • the key 9 is pivotally mounted by means of the studs 31 positioned in the orifices 23 of the cover 2, when the pressure on the cover 2 is maintained in order to reach the closed position, the tabs 33 continue to slide on the lugs 60 so as to cause a pivoting of the key 9 against the flexible wall 21. More precisely the rib 32 bears against the flexible wall 21 which is deformed towards the circular rib 25. When the free ends of the chins 60 and notches 34 come into contact, a maintenance of the pressure on the cover 2 passes the notches 34 under the lugs 60 that is to say that the notches 34 are positioned against surface 60 against the shank 60.
  • the key 9 is in the rest position and the notches 34 are engaged in the lugs 60 so that despite the constant biasing of the spring 10 to the open position, the lid 2 is held in its position closed by contact of the surface 35 against the surface of the chins 60 opposite the ramp 61.
  • the key 9 If the user releases the pressure of the key 9 at this stage, by the biasing of the flexible wall 21 on the rib 32, the key 9 returns to its rest position with the notches 34 taken in the lugs 60 as previously described.
  • the fingers 56 undergo a slight deformation so that their end portion is pushed outwards. Once the legs 33 have passed the ramps 59, the distance between the surfaces 58 being sufficient to accommodate the legs 33, the fingers 56 resume a rest position.
  • the spring 10 urges the lid towards the open position and nothing prevents the lid from pivoting towards its open position.
  • the tabs 33 deviate from the wall 40 of the hubcap, they remain in contact with the end of the fingers 56 and the button 9 remains in a pivoted position separate from the rest position until, the cover 2 having pivoted by a sufficiently large angle, the contact ceases between the tabs 33 and the end of the fingers 56.
  • the pivoting of the cover 2 is facilitated by the slightly inclined direction of the surfaces 58.
  • edge 13 of the lid 2 abuts against an edge 70 forming a stop of the hubcap 4.
  • the edge 70 is the edge of the hubcap 4 which extends between the bosses 45.
  • the positioning of the end of the fingers 56 defines a threshold for the pivoting of the key 9.
  • the key 9 has rotated in the angle below the angle that allows the crossing of the legs 33 of the end of the fingers 56, when releasing the pressure exerted by pressing on the central zone 28 of the support wall 27 of the key 9, this key 9 returns to the rest position. If the pressure exerted on the key 9 is such that the pivot angle allows the tabs 33 to cross this end of the fingers 56 then the key 9 can no longer return to its rest position before the cover 2 has pivoted an angle sufficient for the lugs 33 to be released from any stress due to the end of the fingers 56.
  • the lugs 160 are provided directly from the surface of the front side wall 150 of the hubcap 104 opposite the annular seal 142.
  • the lugs have a ramp 161.
  • the fingers 156 are limited to profiled lugs and protruding from the wall 140 and having a ramp 159 and a plateau surface 158.
  • the surface 158 extends transversely to the wall 140.
  • the fingers 156 are molded integrally with the hubcap 140.
  • the cooperation of the key 109 and more particularly the tabs 133 with the chins 160 is the same as before.
  • the wall 127 of the key 109 is pressed so that the rib 132 bears against the wall 121.
  • the tabs 133 come into contact with the ramps 137 with the ramps 159 and the tabs 133 cross the defined threshold. by the fingers 156.
  • the fingers are reported on the hubcap.
  • some of the different notches, fingers and tabs are made of a plastic material allowing them to be compressible so as to allow the crossing of different ramps.
