Definitions

  • each contact bracelet is a function, in particular, of its geometry and the number of points of contact it provides with the two surfaces between which it is interposed.
  • the ability of the connector to withstand current intensities higher than those normally expected for an individual bracelet is traditionally obtained by multiplying the number of bracelets which are then placed one after the other.
  • the object of the invention is essentially to remedy these drawbacks and to propose an improved arrangement of a connector with several contact bracelets which is more compact, lighter and possibly less expensive than the connectors currently used and which is furthermore of more satisfactory and safer electrical operation.
  • an electrical connector as defined above is essentially characterized, being arranged in accordance with the invention, in that the first and second connector elements have, respectively around the socket and the pin, at least one annular skirt extending axially and at least one contiguous annular recess shaped and positioned to receive the annular skirt of the other connector element when the two elements are coupled to each other, and in that it comprises at least two contact bracelets arranged concentrically and approximately mutually aligned radially, these bracelets being interposed between the facing surfaces of the socket, pin and mutually interlocked skirts when the two connector elements are coupled to each other.
  • each bracelet is retained in an annular groove hollowed out in one of the cooperating surfaces of the sleeve and / or of the pin and / or of the skirts.
  • all the contact bracelets individually associated with a pair of cooperating surfaces of the socket and / or of the pin and / or of the skirts are worn by the surfaces which have the same radial orientation (facing radially inwards or turned radially outwards); this arrangement leads to an advantageous arrangement in that it provides protection of the bracelets against impact when the two connector elements are not coupled and which consists in that all the contact bracelets are carried by the surfaces which are turned towards inside and which are sheltered when the two connector elements are not assembled to each other.
  • each contact bracelet is, in a manner known per se, constituted by a ribbon of an elastically deformable material having a conformation approximately in Greek or a similar conformation giving it a radial elasticity.
  • each contact bracelet is, in a manner which is also known per se, bent transversely so as to be supported by its edges on its support surface and centrally on the cooperating surface in look of the support surface.
  • the arrangement in accordance with the invention (bracelets arranged concentrically) can be combined with the arrangement previously used (bracelets arranged one after the other) so that, when a large number of contact bracelets is necessary, the compromise thus obtained makes it possible to reduce the longitudinal dimension of the connector without however causing an excessive increase in its diameter.
  • the connector can be equipped with several bracelets arranged in several concentric groups of, each, several bracelets arranged one after the other.
  • FIGS. 1 and 2 very schematically represent an electrical connector arranged in accordance with the invention and shown respectively in two different functional positions (respectively uncoupled and coupled).
  • the electrical connector shown in the drawings consists of two connector elements which can be coupled together, namely a connector element A, comprising a body 1 provided with an axial bore 2 opening onto the front face of said body 1 and forming a socket, and a connector element B, comprising a body 3 provided with a part projecting axially on the front face of said body and forming a pin 4.
  • This pin is dimensioned and shaped to be housed in the bore 2 when the two elements A and B are coupled one to the other. 'other.
  • element A will be called “female element” and element B will be said "male element”.
  • the two connector elements A and B are shaped, in their respective rear parts (not shown in the drawings), to be connected to respective conductors.
  • the two bodies 1 and 3 of the elements A and B are, at least in their respective front parts, produced in massive form, that is to say that the spindle 4 and the sleeve 2 are machined (for example by turning) in metallic blocks, for example of copper, the surfaces useful for the conduction of electric current being able to be covered with gold.
  • annular contacts 5 in the form of a bracelet which are interposed between facing surfaces belonging respectively to element A and to element B.
  • the contact bracelets 5 are arranged, no longer axially one after the other between pin and socket as was the case in the prior connectors (see for example document FR-2 622 361), but concentrically with each other being approximately radially aligned.
  • the bodies of elements A and B are arranged specifically to support the contact bracelets. To this end, it is necessary multiply the number of cooperating annular surfaces of elements A and B in correspondence with the number of contact bracelets to be used.
  • the embodiment shown in Figures 1 and 2 is arranged to include two contact bracelets. To this end, the bore 2 is hollowed out in a portion of the body 1 of annular shape forming an annular skirt 6 which has an outside diameter smaller than that of the body 1 so as to delimit an external annular clearance 7 a which ends in a external annular shoulder 7 b against which a sealing ring 8 is put in place.
  • the body 3 of the male element B has an annular skirt 9 surrounding the spindle 4 at a radial distance and defining therewith a annular housing 10.
  • This housing 10 is dimensioned and configured to receive the annular skirt 6 of the female element A when the two elements A and B are coupled, while then the skirt 9 of the male element B engages in the external clearance 7 a and surrounds the skirt 6 of the female element A while being abutted against the seal 8 (see fig. 2).
  • annular gutter 11A In the lateral face of the bore 2 is hollowed out an annular gutter 11A in which is disposed a contact bracelet 5A.
  • annular gutter 11B In the outermost lateral face of the housing 10 is hollowed out an annular gutter 11B in which is disposed a contact bracelet 5B.
  • each contact bracelet 5A and 5B are shaped in any way appropriate to their function; in this regard, reference may be made in particular to document FR-2 622 361.
  • each contact bracelet is constituted by a ribbon of an elastically deformable material having a conformation approximately in Greek or a similar conformation conferring on it a radial elasticity.
  • each bracelet is bent transversely to be supported by its edges on the bottom of the groove which supports it and centrally on the cooperating surface located opposite and belonging to the other element, when the two elements A and B are coupled (fig. 2); when the two elements are not coupled, the central part of the bracelet projects radially beyond the surrounding surface (fig. 1).
  • all the straps 5 are arranged with their respective transverse concavities oriented in the same radial direction.
  • the two straps are carried by the internal face of the bore 2 and of the annular housing 5, otherwise by the annular surfaces of the connector elements A and B which have the same direction of radial orientation; here the two surfaces are turned radially inwards, an arrangement which offers the advantage that the straps are protected against external shocks when the two elements A and B are not coupled.
  • the number of skirts and annular grooves provided on elements A and B depends on the number of contact bracelets that the connector must include. However, to avoid an excessive increase in the diameter of the connector when the number of bracelets is large, it is possible to envisage a combination of the arrangement previously used and the arrangement in accordance with the invention, that is to say of distributing the bracelets in several groups of each, several bracelets arranged one after the other.
  • the connector represented in FIGS. 1 and 2 could be equipped with four bracelets, namely two bracelets 5A arranged one after the other on the female element A and two bracelets 5B arranged one after the other on the male element B.
