Definitions

  • the invention relates to a sealed electrical connection device comprising two conjugated connection elements.
  • connection devices comprising two conjugated connection elements, one of which comprises an outer casing, and which are each provided with electrical contacts intended to cooperate with each other in a connection position, after coupling of said elements obtained. by a first relative translational movement, followed by a rotation and a second translation, the connection elements being at the end of said rotation in an intermediate position of rest in which said elements are held temporarily between them, without connection of contacts, while the connection is established between the contacts of the two connecting elements at the end of the second translation determining said connection position.
  • one of the elements constitutes a base socket, or the mobile socket of an extension or a connector, while the other element can be a fixed connector base or provided with a handle to form a form.
  • Means have already been devised for sealing the element under tension in the absence of coupling, for example by providing a cover.
  • EP-A1-1 102 362 discloses a base provided with a seal formed therein, between an insulating block and a housing.
  • connection device as described above, in particular for problems of guiding the connection elements with each other, the impossibility of a rotation of said connection elements on one another, the impossibility of adding a security disk, ...
  • the invention proposes a device of the aforementioned type about the document EP-A1-1 102 362 and which thus comprises two elements which mate in the manner described above but which is remarkable in that the conjugate connecting element of the element comprising the outer casing, is provided with an outer tubular flexible seal fixed by one end to said element and provided with at least one annular abutment end surface which is intended to cooperate by contact with a conjugate surface provided on said casing of the other element, and which comprises a rigid or semi-rigid ring provided with means guiding in translation during the coupling of the connecting elements, so that a sealing is ensured between said connecting elements from at least their intermediate rest position to their connection position because of the cooperation of the annular abutment surface of the abutment of the seal and the mating surface of the casing, said seal being further bent in the connecting position of u fact of the second relative translational movement of the connection elements, while said conjugate surfaces are arranged to allow sliding on one another during the rotary movement of said connecting elements.
  • the guide means comprise a sheath integral with the ring of the seal, which is slidable on a fixed part of the connecting element provided with said seal and in this case for example, the sheath further comprises an elastic means of recall in initial position of extension of the joint.
  • the surface of the housing intended to cooperate with the front surface of the seal is frustoconical and striated.
  • the seal is folded accordion, but according to another particularly advantageous embodiment, the seal is arranged to undergo a simple folding inward during the connection maneuvers.
  • the seal has a circular cylindrical portion at its end fixed to the corresponding connection member, extended by a frustoconical portion which terminates in the annular end face abutment forming a shoulder.
  • the conjugate means for guiding in rotation and retaining in the intermediate rest position of the connection elements are arranged, on the one hand, on the end ring of the seal and, on the other hand, at the end of the housing, said ring extending beyond the annular abutment end surface of the seal and being dimensioned to come at least partly inside said housing.
  • said conjugate means of rotation guide and intermediate position retaining are of type pins and ramps, said ramps having a slope which increases the pressure of the annular end surface of the seal abutment on the conjugate surface of the housing.
  • FIG. 1 shows a mobile extension socket 1 ( figures 1 and 3 to 5 ), intended to cooperate with a form 2 ( figures 2 and 3 to 5 ), the movable socket as the plug each forming, as shown, a handle.
  • the plug 1 and the plug 2 are each provided with contacts in the form, for example, of end contacts, such as contact 3 diagrammatically in the drawings, for the plug, and pins, such as 4a, 4b, for the plug .
  • the contacts 3 could moreover be cells rather than end contacts in order to form said contacts with pins and cells, the invention being also independent of the nature of the contacts.
  • the contacts of the socket are supplied with current by electric cables shown schematically in 6a, 6b.
  • the contact pins 4a, 4b of the plug are also connected to electric cables 7a, 7b, themselves intended to be connected to a device or a device to be supplied with current.
  • the contacts 3 of the socket are mounted in an insulating block 8 surrounded here in part by a sleeve 9 mounted free in translation and provided with an elastic return means 10, in the form of a helical spring in this example.
  • the sleeve 9 terminates in an annular portion forming a ring 11 which, in this example, surrounds in at least the initial state at least in part the safety disc 5.
  • the plug 2 has an outer casing 12 surrounding the pins 4a, 4b while the movable plug 1 is provided with an outer tubular flexible seal 13 fixed at one end to a portion of said plug and at its other end to the ring 11.
  • the seal 13 has a circular cylindrical portion 13a of the side fixed to the movable socket 1, which is extended by a frustoconical portion 13b.
  • the surface 15 of the housing 12 is substantially frustoconical and ridged for better contact.
  • the materials used for the casing and the seal and / or the state of the surfaces 14 and 15 are chosen to allow a certain sliding of said surfaces on one another during a rotary movement as will be specified hereinafter .
  • the socket 1 and the plug 2 are provided with means for guiding rotation and retaining the plug 2 in the socket 1.
  • the pins 4a, 4b are introduced into openings formed for this purpose in the safety disk 5, the angular positioning and the first translational movement being guided by the lugs 16 and the ramps 17a, 17b of the elements, while the surfaces 14 and 15, respectively of the seal 13 and the housing 12, come into contact, that is to say abut against one another.
  • Ramps 17a and 17b clearly visible on the figure 1 then allow a guide in rotation of the plug 2 and the socket 1, the surfaces 14 and 15 sliding on one another until said plug 1 and said plug 2 take the position shown on the figure 4 , so-called rest position.
  • contact surfaces 14 and 15 is sufficient to ensure a seal between the housing 12 of the plug 2 and the seal 13 of the socket, the latter having already or not already undergoes a first slight wrinkling which will be discussed below.
  • the seal may result from the simple contact of the surfaces 14 and 15, said surfaces may have various forms to improve said seal.
  • Ramps 17a, 17b may also have a certain slope to allow a slight tightening.
  • seal 13 can be considered according to other embodiments than the one shown. Said seal must be flexible to be able to undergo a wrinkling resulting in longitudinal shortening.
  • the seal may, for example, be a bellows seal, the pleated accordion type which can undergo during the last translation a folding and a shortening by compression of said seal.
  • the embodiment shown is less cumbersome and makes it possible to reduce the diameter of the apparatus while limiting the length of the fact that the seal of this embodiment can work (folding and unfolding) in a cylindrical volume shorter and less wide. Moreover, such a shape avoids the accumulation of dirt that is inevitable with an accordion shape.
