Definitions

  • the invention relates to an electrical connector of the type comprising a base fixed on the wall of an appliance such as an electric or electronic box, an electric cable head intended to engage in this base, two sets of complementary contact parts. a first set of which is arranged in the base and the second set in the cable head, each contact piece of one set being designed to engage with a contact piece complementary to the other set in order to ensure electrical connections between the device and the electrical cable and it is intended to allow prolonged use of this connector in immersion in water after having made the connection in air.
  • Such connectors are known for example from documents US-A-3,963,297 and US-A-3,816,641.
  • the electric cable comprises, from the outside to the inside, at least one insulating outer sheath, a metal frame, an insulating inner sheath and individually insulated electrical conductors.
  • the electric cable head comprises a metallic structure, of generally tubular shape, receiving the end of the electric cable and sealingly holding towards the front end of the electric cable head an insulating contact-carrying part in which the parts are embedded. of the second set. Each of these contact parts is electrically connected to the end of one of the electrical conductors of the cable. So that the connector can be submerged, provision has already been made to stop the outer sheath of the cable at a distance from the front end of the electrical cable head greater than the distance at which the end of the inner sheath ends.
  • An objective of the invention is to further increase the life under water of an electrical connector of the type which has just been described in order to reach the durations currently desired and it has been found that this result can be achieved by separating the insulated electrical conductors of the cable from one another in a space between the end of the inner sheath and the contact-holding insulating part and by inserting into this space in a sealed manner vis-à-vis the metallic structure of the cable head, an insulating plug crossed in a sealed manner by each of the insulated electrical conductors, thus spaced apart from one another.
  • This base comprising a metal part which forms a first tubular portion, for engagement in the wall, a second tubular portion, for receiving the head of the electric cable and a flange between these two tubular portions, it has been found that it is advantageous to provide both an annular seal on the first tubular portion and an annular seal on the flange, in contact with the wall.
  • a base 2 On the wall 1 of a device not shown is mounted a base 2 inside which are fixed pins 3, partially embedded in a sealed and insulating filling 4, electrically connected by connections 5 to organs arranged at the inside of this unit.
  • This base 2 is designed to receive the head 6 of an electric cable 7.
  • This head 6 comprises a metallic structure, of generally tubular shape, consisting of an axial succession of parts fitting into each other. We can distinguish: a central tubular metal part 8, a front tubular metal part 9 mechanically linked to the previous one by overlapping the neighboring ends and application of an auxiliary sleeve 10 linked to the part 9 and retained longitudinally on the part 8 by a circlip 11, a rear tubular metal part 12 partially overlapping the part 8.
  • These metal parts, as well as others which will be mentioned, are, for example, made of stainless steel or of marine bronze UA9F .
  • the cable 7 comprises an outer insulating sheath 13 which is stopped in a transverse plane 14 located near the entry of the cable into the cable head 6, a metal frame 15 which is radially separated, a little further forward, to be retained between the rear tubular metal part 12 and a metal fixing part 16 forming a nut and screwing onto the part 12, an internal insulating sheath 17 which is stopped in a transverse plane 18 located further forward in the cable head and electrical conductors individually isolated 19.
  • the electrical conductors 19 are spaced from each other in the cable head 6 in the space comprised longitudinally in front of the inner sheath 17 and an insulating plug 20 is formed around these conductors spaced from each other.
  • This insulating plug 20 comprises a front portion made of elastomer and a rear portion made of hard plastic. It is held tightly in the metal structure.
  • a spacer 22 separates the plug 20 from an insulating contact-holder part 23 in which are sockets 24 provided for receiving the pins 3 when the cable head 6 is introduced into the base 2. These sockets 24 are attached to the ends of the conductors 19.
  • the base 2 comprises a metal part which forms a first tubular portion 25 engaging in an opening in the wall 1, a second tubular portion 26 internally receiving the front end of the cable head 6 and a flange 27 between these two tubular portions.
  • An annular seal 28 is provided on the tubular portion 25 and an annular seal 29 on the flange 27, in contact with the wall 1.
  • two annular seals 30 are provided, arranged on sections with different internal diameters.
  • An overmolding 32 in an elastomer is applied to the inner sheath 17 and the metal part 8.
  • An overmolding 33 in an elastomer is applied to the outer sheath 13, all the metal parts 16, 12, 8 and 10 and against the part metallic 9. This overmolding 33 therefore covers the entire metallic structure with the exception of the front part of the front metallic part 9 surrounded by the external sleeve 31.
  • each electrical conductor can be tested during manufacture by mounting the connector on the wall of an enclosure subjected to a high vacuum, while helium is injected into the rear part of the cable head. .
