Definitions

  • the invention relates to an electromagnetic shielded electrical connector equipped with a ground ring and a coding system adapted to be mounted around the connector.
  • the invention also relates to a method of mounting the connector.
  • the invention has applications in the fields of connectivity and, in particular, in the field of aeronautical connectivity.
  • the connectors are protected from the effect of electromagnetic fields in the vicinity of said connector by a shield.
  • Said shield protects the internal connections of the connector against the effects of certain electromagnetic couplings. It protects the internal connections of the connector including radio frequencies and electrical noise. The shielding thus ensures the electromagnetic immunity of the electrical connector.
  • shielding In the field of aeronautical connectivity, such electromagnetic shielding is imposed by the standards in force in this field. Said shielding is for example in the form of a circular wire mesh placed between a connector (male or female) and the locking ring of a complementary connector (respectively female or male) to ensure electrical continuity when the connectors are mated. This wire mesh is referred to as the "ground ring”.
  • FIG. 1A represents a connector 1 provided with a locking ring 30.
  • FIG. 1B represents the housing 10 of the connector 1 before the installation of the locking ring 30.
  • This connector housing 10 has a substantially cylindrical shape comprising, according to this exemplary embodiment, first, second and third cylindrical sections 13, 12, 11 of different diameters.
  • the ground ring 20 is mounted around the connector housing 10 in a central area of said housing. More specifically, the earth ring 20 is mounted around the first section 13, between the keying keys 40 of said section 13 and the second section 12 whose diameter is greater than that of the first section 13.
  • the connector housing 10 comprises, according to the prior art, a plurality of foolproof keys 40 whose role is to allow only the coupling of the appropriate complementary connector.
  • the keying keys 40 have different shapes, dimensions and arrangements from one connector to another. In this way, only a complementary connector having a keying system adapted to the keying keys 40 of the connector 1 is able to be coupled with said connector 1.
  • the ground ring 20 is generally made of an elastic metal material.
  • This elastic metal material must have, on the one hand, a conductivity sufficient to ensure electrical continuity between the connector and the complementary connector and, on the other hand, sufficient elasticity to allow the passage of the ground ring over the keying keys 40.
  • the deformation undergone by the ground ring 20 is relatively large, to the point of being able to generate permanent deformation of said ring. Indeed, if the material in which the ground ring is formed is too stretched, it can not resume its original shape.
  • ground ring 20 is deformed permanently, the electrical continuity between the complementary connectors is no longer ensured. It is therefore necessary, after mounting the ground ring 20 around the connector housing 10, that an operator verifies, by a visual check, whether the ground ring is functional. In the case where the ground ring has permanent deformations and is therefore not functional, then the ground ring must be removed and replaced by a new ground ring.
  • the invention aims to overcome the disadvantages of the prior art.
  • the invention relates to an electrical connector having an electromagnetic shield whose connector housing is made in two parts: a connector body and a foolproof section, the foolproof section being mounted on the connector body after installation of the ring of mass.
  • the ground ring does not need to be slipped over the keying pins, which avoids the risk of permanent deformations.
  • the keying section being independent of the connector body, and mounted after the installation of the ground ring, said ground ring is advantageously mounted without excessive deformation and therefore without risk of permanent deformation.
  • the front section has a circular groove formed on the periphery of said section, and the foolproof section is an open ring adapted to be fitted into the circular groove.
  • the foolproofing section is made of a material able to deform during the setting in place of said keying section and to resume its initial shape after installation of said keying section in the circular groove.
  • the rear section comprises a groove and the foolproofing section comprises a locking element in the form of a key adapted to fit into said groove.
  • the front section comprises a grooved section and a smooth section
  • the foolproof section is a cylinder section adapted to be fitted around a grooved section.
  • the keying section has, on its periphery, keys foolproof.
  • the keying keys have shapes, dimensions and arrangements adapted to a keying system of a complementary connector.
  • the foolproof section being independent of the connector body, many kinds of foolproof keys can be used to meet the standards in force.
  • the ground ring is made of an electrically conductive material with low deformation.
  • the electromagnetic shielded connector object of the invention comprises a connector housing in two parts: a connector body, around which is mounted a ground ring, and a keying section mounted on the connector body after installation of the ground ring.

  • the Figure 2B shows a perspective view of a keying section 15 to be mounted on the body of this connector 100.
  • Figure 2C shows the keying section 15 mounted on the connector body 100 to form a connector housing 10.
  • the connector body 100 is a cylindrical element capable of receiving an insert as well as electrical contacts (not shown in these figures).

Indeed, the front section 14 comprises on its periphery a circular groove 141, positioned substantially in the center of said front section 14. This circular groove 141 has dimensions adapted to receive the foolproofing section 15 shown in FIG. Figure 2B .
  • the foolproofing section 15 is an open ring 151 equipped on its outer surface with keying keys 152.
  • This open ring 151 is made of a material capable of deforming to allow its installation in the circular groove 141 of the front section. 14, and resume its original form once installed.
  • said ring consists of an expanded shape memory material and in the martensitic state. so that its heating causes its shrinkage during the reversion to the austenitic state, or alternatively in a so-called superelastic state.
  • said ring is made of thermoplastic polymer, reinforced or not by short fibers which allows its economic realization and offers the possibility of having a direct visualization of the keying code by color.
  • This ring 151 has an opening 154 of angular dimension adapted to ensure the interlocking of said ring around the circular groove 141 while preventing inadvertent withdrawal of said ring, for example when the connector is subjected to vibration.
  • said opening corresponds to an angular opening of the order of 30 °
  • the open ring 151 has a thickness (excluding keying keys) approximately equal to the height of the circular groove 141 of section 14. Thus, when the open ring 151 is installed in the circular groove 141, the surface of the zone Rear 16 of the connector body 100 is substantially uniform throughout its length. Only the foolproof keys 152 project from this rear zone 16.

  • Said groove 143 is a housing formed in the surface of the end zone 142 of the front section 14, of approximately the same height as the thickness of the locking element 153 of so that when the keying section 15 is installed around the front section 14, the end zone 142 has a uniform surface.
  • This locking element 153 associated with the groove 143 maintains the coding section 15 within the front section 14 and prevents any rotation of said foolproof section, even in the presence of vibrations.
  • the connector housing of the invention is then formed.
  • a complementary connector having a keying system adapted to the foolproof keys 152 can then be coupled with the connector of the invention.
