Definitions

  • the present invention relates to a seal mounted in a waterproof connector.
  • the invention relates to a seal intended for be used with connectors comprising an element female housing having a skirt intended to receive a male housing element and in which extend pins intended to cooperate with connection members female electrical components of the male housing element, said gasket being mounted in the skirt and having conduits crossed by the pins.
  • One of the aims of the present invention is to make a joint of the above type which allows the elements to be safely coupled and uncoupled to decrease its effectiveness.
  • the seal according to the invention is mounted in waterproof electrical connectors of the type comprising a male housing element and a female housing element having a skirt intended to receive the male housing element, said female housing element comprising an insulating element in which are housed extended connection members by pins that protrude into the skirt, while the male housing element is provided with an insertable extension in the skirt and in which an insulating body is fixed receiving organs of female electrical connections intended to cooperate with the pins,
  • the seal being type of flexible and elastic material comprising a base with chimneys pierced with conduits for passage pins, said seal being engaged in the skirt for bear, by its base, against the insulating element of said element female housing, said seal being characterized in what each conduit, starting from the base, presents a first cylindrical part having a diameter slightly lower than that of the pins and extended by part in the shape of an inverted truncated cone, itself extended by a part in the shape of a truncated cone, terminated by a second cylindrical part, while the base is bordered
  • Another advantage of the invention is that the seal does not constitute a brake requiring an increase in insertion force of the male housing element in the element female housing.
  • Figure 1 is a plan view of a joint, according to the invention.
  • Figure 2 is an enlarged sectional view scale, according to line 2-2 of figure 1.
  • Figure 3 shows in section a box of connections electrics fitted with a seal, according to the invention, in position disassembled.
  • Figure 4 is a sectional view of the housing electrical connections of figure 3 in mounted position.
  • Figure 5 is a view of a detail at a larger ladder.
  • the joint shown in Figures 1 and 2 is made in a flexible and elastic material and has a base 1, a peripheral edge 2 and a series of chimneys 5.
  • Each chimney has a pipe 3 which, at near the base 1, has a first cylindrical part 3a connected on the opposite side to the base 1 to a inverted frustoconical part 3b whose large base is itself connected to a tapered part 3c completed by a second 3d cylindrical part.
  • the diameter of part 3a is slightly smaller to that of the 3d part.
  • Figures 3, 4 and 5 show a connector intended to receive a seal, according to the invention.
  • the connector comprises a first element of female housing 10 comprising a metal casing 11 extended, on one side, by a skirt 12.
  • an insulating element 13 supporting a series of electrical connection members 17 connected to electrical conductors and extended by pins 14.
  • the end of the element 10, opposite the skirt, is filled with either an adhesive or a resin 16 which tightly closes the element 10 including the conductors 15.
  • the seal is mounted in the skirt 12 so that its base 1 cooperates with the corresponding face 13a of the insulating element 13, a thin layer of adhesive being applied on this face.
  • the parts 3a of the conduits 3 have a diameter slightly smaller than the diameter of pins 14, while that the 3d parts have a diameter greater than that of said pins.
  • the female housing element 10 has, at each end (see Figure 5), a nut 18 for fixing it with a male housing element 20.
  • the male housing element 20 includes an envelope metallic 21 having an extension 22 intended to be inserted in the skirt 12 and in which is mounted an insulating body 24 in which are housed and fixed female electrical connection members 25 intended for receive, each, a pin 14. Each member 25 is connected to a conductor (not shown).
  • the male housing element 20, on the opposite side at extension 22, is closed with an adhesive or a resin 27.
  • the male housing element 20 comprises, at each end, a captive screw 28 (see Figure 5) intended to be screwed into nut 18 to ensure assembly of the two housing elements.
  • the free end of the insulating body 24 comes bear against the edge of the conduits 3 opposite the base and thus tends to slightly crush the joint so that the parts 3d, sliding slightly on the pins, enclose these.
  • Housing elements can be coupled or uncoupled many times without risk to the joint.
