Definitions

  • the electrical connector is for example a power connector, that is to say it is adapted to transmit a current of an intensity greater than or equal to 10A.
  • a connector creates a risk for a user who comes into electrical contact with the male contact or the female contact.
  • caps In order to reduce or eliminate this risk, it is known to place caps on the contacts. However, the caps must be removed before putting the connector into the inserted configuration. This makes use complex, and exposes the user to risk when the caps are removed and the connection is not yet made.
  • the document FR 3 644 450 A1 of the applicant describes a connector comprising an insulator inserted in the housing formed by the female contact.
  • This insulator comprises a cylindrical cage, and a central finger extending axially. The space between the finger and the bars of the cage is restricted and prevents a user from directly touching the blades of the female contact.
  • the finger of the insulator is received in a recess of the insertable part of the male contact, and the insertable part is received between the finger and the bars of the cage. Consequently, the male contact and the insulator are quite complex to manufacture.
  • the insulation reduces the risk of contact, it does not prevent a user or a person from indirectly touching the slats by introducing a conductive object into the housing.
  • An aim of the invention is therefore to provide an electrical connector reducing the risk of electrification of a user or a person, while allowing an efficient electrical connection and which is simple to manufacture and at a competitive price. .
  • the invention relates to an electrical connector according to claim 1.
  • the electrical connector comprises one or more of the characteristics corresponding to claims 2 to 9, taken in isolation or in all technically possible combinations.
  • the electrical connector 2 comprises a male contact 4 and a female contact 6 movable between an inserted position ( Figure 4 ), in which an electrically conductive insertable part 8 of the male contact is inserted along an insertion axis D in a housing 10 defined by the female contact, and a non-inserted position ( figures 1 And 3 ), in which the male contact is away from the female contact.
  • distal we mean, for each of the contacts, the side defined by the direction of insertion along the insertion axis D.
  • proximal we mean the side opposite the insertion along the axis insertion D.
  • the term “conductor” means a material whose electrical resistivity at 300 K is for example less than or equal to 10 -5 ⁇ .m.
  • the term “insulator” means a material whose electrical resistivity at 300 K is for example greater than or equal to 10 5 ⁇ .m.
  • the male contact 4 and the female contact 6 are adapted to be in electrical contact on the distal side with two electrical cables (not shown).
  • the female contact 6 comprises a body 12 advantageously defining a housing 14 for receiving one of the two electrical cables, and a plurality of strips 16 projecting axially from the body, and distributed angularly around the insertable part 8 of the male contact 4 in the inserted configuration ( figure 4 ).
  • the female contact 6 includes a protection system 18 to protect a user (not shown).
  • the female contact 6 further comprises several annular retaining members 20 arranged around the strips 16 to press the strips onto the insertable part 8 in the inserted configuration.
  • the female contact 6 comprises a single containment member 20, or does not include one.
  • the body 12 and the lamellae 16 are conductive. They are for example made of aluminum, aluminum alloy, copper or copper alloy.
  • the body 12 and the lamellae 16 define the housing 10 receiving the insertable part 8 in the inserted configuration.
  • the body 12 advantageously defines a recess 22, for example cylindrical in shape, at the bottom (on the proximal side) of the housing 10.
  • the strips 16 are radially flexible and define gaps 24 between them ( figure 2 ) extending axially.
  • the lamellae 16 are at least two in number. In the example shown, there are ten strips 16.
  • the slats 16 radially delimit the housing 10.
  • the protection system 18 comprises an insulating envelope 26 surrounding the strips 16 around the insertion axis D, and extending axially at least along the strips, the envelope being adapted to prevent electrical contact radially between a user and the slats.
  • the protection system 18 comprises an insulation member 28 movable in axial translation relative to the body 12 between a rest position intended to be occupied in the non-inserted configuration, and a depressed position intended to be occupied in the inserted configuration.
  • the protection system 18 includes a return mechanism 30 adapted to return the insulating member 28 from the depressed position to the rest position.
  • the envelope 26 extends axially also along a part of the body 12.
  • the envelope 26 is for example fixed on the body 12.
  • the envelope 26 advantageously comprises an end part 32 forming a rim 34 located in an axial extension of the lamellae 16 and surrounding the insertion axis D.
  • the envelope 26 advantageously has a general shape of revolution around the insertion axis D, and defines for example gills 36 distributed angularly around the insertion axis.
  • the gills 36 extend for example axially from the rim 34 in the proximal direction.
  • the rim 34 is advantageously adapted to prevent axial electrical contact between a user and distal ends 38 of the blades 16.
  • the rim 34 defines an entrance 40 to the housing, across which the insulation member 28 extends in the rest position.
  • the return mechanism 30 comprises for example a spring 42 compressed axially, and located axially between the insulation member 28 and the bottom of the housing 10.
  • the spring 42 is located partially in the recess 22 and is for example supported on the bottom of the recess.
  • the insulation member 28 is adapted to at least partially close the inlet 40 of the housing 10 and prevent axial electrical contact, direct or indirect, between the user and the slats 16.
  • the insulation member 28 In the rest position at rest, the insulation member 28 abuts axially against a stop 44 formed by the female contact 6, in the example by one of the containment members 20 (the most proximal).
  • the insulating member 28 In the depressed position, the insulating member 28 is pushed towards the bottom of the housing 10 by the male contact 4 relative to the rest position.
  • the insulation member 28 comprises for example a proximal portion 46 axially relative to the body 12, the proximal portion defining a housing 48 adapted to receive a distal end 49 of the spring 42 of the return mechanism 30.
  • the insulating member 28 comprises for example a main part 50 adapted to slide in the housing 10, and a plurality of projections 52 extending radially from the main part, and engaged in the interstices 24.
  • the main part 50 has for example a radially outer surface 54 that is cylindrical.
  • the projections 52 are adapted to slide axially in the gaps 24 between the rest position and the depressed position, and to abut on the stop 44 in the rest position.
  • the projections 52 form, for example, pawns.
  • the male contact 4 comprises for example an electrically conductive body 56 from which the insertable part 8 forms an axial projection.
  • the male contact 4 further comprises an electrically insulating envelope 58 surrounding the insertable part 8 around the insertion axis D and extending axially along the insertable part 8.
  • the male contact 4 advantageously comprises a member d insulation 60 covering a distal end 62 of the insertable part 8 relative to the body 56.

  • the insulation member 60 is for example adapted to be snapped onto the distal end 62.
  • the insulation member 60 of the male contact 4 and the insulation member 28 of the female contact 6 are for example adapted to fit into each other, one partially encapsulating the other, in the configuration inserted.
  • the electrical connector 2 is for example initially in the non-inserted configuration ( figure 1 Or Figure 3 ).
  • the insulating member 28 of the female contact 6 is in the rest position and closes the inlet 40 of the housing 10.
  • the return mechanism 30 maintains the insulating member 28 in the rest position.
  • the insulation member 28 abuts axially against the stop 44.
  • the envelopes 26, 58 prevent or limit radial electrical contacts between the user and, on the one hand, the slats 6, and, on the other hand, the insertable part 8.
