Definitions

  • the present invention relates generally to the bases of plug.
  • such a socket outlet has at least two phase cells and neutral by which it is able to receive the pins of a plug complementary current.
  • these are generally tubular cells, which are each individually intended to receive such a pin by one of their axial ends, and the corresponding outlet of which is flared to facilitate the introduction of this pin.
  • Each of these cells must be electrically connected to a terminal connection suitable for connecting an electrical conductor.
  • a contact block of conductive material comprising, in one piece, on the one hand, a cage, which is suitable for constitution of the connection terminal, and, on the other hand, the corresponding cell.
  • connection terminal must come from one or the other of two very different technologies.
  • connection terminal automatic using a leaf spring or any other elastic organ as is the case in the German utility model mentioned above, either from a screw connection terminal, sometimes called connection terminal to wafer, using a clamping screw in engagement with a nut,
  • the present invention generally relates to a provision to avoid this drawback.
  • a contact block for base socket outlet of the kind comprising, in one piece, on the one hand, a cage, which is specific to the constitution of a connection terminal, and, on the other part, a generally tubular alveolus which is intended to receive a pin by one of its ends, and which has, for this purpose, a flared outlet at this end, this contact block being generally characterized in that the cell has a flared outlet at each of its ends.
  • the contact block according to the invention is advantageously reversible as regards the cell which it comprises.
  • connection terminal which it must include
  • the block contact according to the invention is advantageously suitable by itself for one and the other of the two technologies to be applied.
  • a block of contact 10 comprises, in one piece, on the one hand, a cage 11, which, according to arrangements described in more detail later, is specific to the constitution of a connection terminal, and, on the other hand, a alveolus 12, generally tubular, which is intended to receive a pin, not represented by one of its ends 13, that is to say by one of its axial ends, and which has, to do this, according to arrangements also described in more detail later, a flared outlet 14 to this end 1 3.
  • the cell 12 has a flared outlet 14 to each of its ends 13.
  • the contact block 10 has a general parallelepiped shape.
  • the cage 11 extends at one of its ends, and the cell 12 at the other of these.
  • the cage 11 has a wall 16, called below for simple convenience bottom wall, two side walls 17, which, arranged in a U with respect to the lower wall 16, come in one piece from this lower wall 16, and which, parallel to each other, are substantially perpendicular to the wall lower 16, and at least one wall 18, hereinafter called for simple convenience upper wall.
  • the cage 11 comprises, parallel to each other, for the same bottom wall 16, two walls upper 18, which operate at the same level, one per wall lateral 17, and whose width is less than half that of the wall lower 1 6.
  • the upper walls 18 are transversely curved, with their concavity turned towards the lower wall 16, and each of them has, along its free edge, a return 19, which is directed towards the bottom wall 16, parallel to the side walls 17, and whose height is reduced compared to that of the latter.
  • this return 19 presents, along its free edge, in the median zone thereof, for each of the upper walls 18, a notch 20, generally rounded.
  • the bottom wall 16, the side walls 17, the upper walls 18 and the returns 19 thereof generally fall within of a regulated surface of which all the generators are parallel to each other, like a tubular body.
  • the cage 11 has, however, for reasons which will appear below, along the edge transverse rear of its lower wall 16, that is to say along that of the transverse edges of this bottom wall 16 which is closest to the cell 12, over at least part of the length of this transverse edge, a rim 21, which, substantially perpendicular to the bottom wall 16, is directed towards the upper walls 18.
  • the lower wall 16 of the cage 11 has, in its central region, a bore 23, the outline is circular.
  • the axis of the cell 12 extends substantially perpendicular to the bottom wall 16 of the cage 11.
  • this cell 12 comprises two shells 24, which, transversely, each extend in an arc, with generators parallel to each other, and which, placed opposite one another, having their concavities turned towards each other, are each respectively formed by strips 25 coming in one piece from the two side walls 17 of cage 11.
  • these strips 25 come from the rear transverse edge of the side walls 17, extending in height on almost all of them, and, after a directed U 26 fold inwards and largely rounded, they form the shells between them 24 constituting the cell 12.
  • each of these shells 24 has, at each of its ends, a lip 28 which, directed obliquely outward, is generally frustoconical.
  • the contact block 10 according to the invention is made of conductive.
  • the side walls 17 of the cage 11 each have a recess 29, for the latching of the assembly in a body of insulating material not shown, and, similarly, the strips 25 which extend these side walls 17 each have in the same goal a recess 30.
  • the cage 11 of the contact block 10 forms a connection terminal to automatic clamping, this cage 11 being fitted internally with a blade spring 31 which has, on the one hand, a support branch 32, through which it bears on its lower wall 16, in practice extending over almost entire surface thereof, and, on the other hand, at least one branch of connection 33, which, connected by an elbow 34 largely rounded to the branch support 32, extends freely, at an angle, in an elastically deformable manner, in the cage 11, towards one or the other of the upper walls 18 of this one.
  • a blade spring 31 which has, on the one hand, a support branch 32, through which it bears on its lower wall 16, in practice extending over almost entire surface thereof, and, on the other hand, at least one branch of connection 33, which, connected by an elbow 34 largely rounded to the branch support 32, extends freely, at an angle, in an elastically deformable manner, in the cage 11, towards one or the other of the upper walls 18 of this one.
  • the leaf spring 31 comprises, parallel to one another, for the same support branch 32, and at the rate of one per upper wall 18 of the cage 11, two branches of connection 33 which are separated from each other by a slot 35.
  • these two branches of connection 33 each form, laterally, along the slot 35, a tongue 36 which, folded substantially parallel to the support branch 32, makes projection on their current part on the same side as this support branch 32, and by which they are each respectively capable of bearing on the free edge of the return 19 of the corresponding upper wall 18 of the cage 11.
  • this tongue 36 is rounded, to the profile of the notch 20 of the returns 19 of the upper walls 18 of the cage 11, and its concavity is turned towards the support branch 32.
  • the support branch 32 of the spring leaf 31 forms, in favor of a punctured 37, a catch tab 38 which projects on its surface outside, towards the elbow 34.
  • the rim 21 of the bottom wall 16 of the cage 11 is there to limit the engagement of the leaf spring 31 in this cage 11.
  • the returns 19 of the upper walls 18 of the cage 11 delimit, then, with these upper walls 18 and the corresponding side walls 17, two engagement inputs 40 in each of which can be engaged, in then being automatically clamped there, the end, previously stripped, of a any electrical conductor not shown.
  • the cell 12 therefore intervenes only by one of its flared outlets 14.
  • the block contact 10 according to the invention is turned 180 ° relative to its previous orientation, the bottom wall 16 of its cage 11 then being at its upper surface instead of being on its lower surface as previously, and this cage 11 forms a screw connection terminal, being equipped, to do this, on the one hand, with a nut 41, of quadrangular contour, which, disposed between its side walls 17, is mounted movable between its wall lower 16 and its upper walls 18, and, on the other hand, a screw clamping 42, which, passing through its lower wall 16 in favor of the bore 23 provided therein, is screwed with this nut 41.
  • the nut 41 is mounted to move between the bottom wall 16 of the cage 11 and the returns 19 of its upper walls 18.
  • the nut 41 is engaged from the front in the cage 11, such that shown diagrammatically by arrow F2 in FIG. 9, and the clamping screw 42 is engaged from above, as shown by arrow F3 in this figure 9.
  • the returns 19 from the side walls 17 of the cage 11 leave the nut 41 all the space necessary for its implantation between them and the bottom wall 16 of this cage 11, and, according to the invention, it is advantageously took advantage of this space for this implantation, and thereby for the implementation of a screw connection terminal.
  • this flared outlet 14 is then the one located at the end 13 of this cell 12 opposite the former.
