Definitions

  • the present invention relates to electrical connectors.
  • a connector in particular of the coaxial type, which can be locked easily and effectively by simple operations such as those permitted by the remote manipulators, while guaranteeing good sealing and good electrical continuity, so that it can be used. in a corrosive or radioactive atmosphere.
  • screw-type connectors are very widely used because the facing threads constitute, at the level of the external conductors, a large exchange surface making it possible to confine the electric field created by possible parasitic currents: there is only small vanishing lines at the ends of the threaded parts and it is avoided that parasitic voltages are created in the central conductor.
  • connectors fitted with a locking system with lugs which allows locking using a manipulator, but the facing surfaces at the connection between the external conductors are generally smaller and
  • the object of the present invention is precisely a connector which overcomes these drawbacks by locking with a simple movement while ensuring good sealing, good electrical continuity and effective protection against parasites.
  • this connector of the type which includes a male part secured to a first conductor and in electrical contact with it and a female portion secured to a second conductor and in contact electric with it, the male part being integral with a first electrical connection body cooperating with a second electrical connection body integral with the female part, this second body comprising a first flexible conductive skirt which can be placed outside of one end of the first connecting body and in electrical contact with it, said end being of substantially annular shape, is characterized in that the second electrical connecting body further comprises a second flexible conductive skirt which can be placed at the inside the end of the first connecting body and in electrical contact with it, the second skirt also being in electrical contact with the first re skirt.
  • the contact surface between the second flexible skirt and the end of the first connecting body is less than the contact surface between the first flexible skirt and said end.
  • This arrangement promotes the external circulation of current because the contact resistance is much lower between the outer skirt and the first connecting body than between the latter and the inner skirt.
  • the latter plays the role of a protective screen vis-à-vis the central conductor by allowing the circulation of parasitic currents and their flow to ground. For this, it must not only be in electrical contact with the two connecting bodies of the male and female parts but also have a high contact resistance with one of the two connecting bodies to reduce the intensity of the currents which pass through it and limit disturbances on the central conductor.
  • the two skirts are split longitudinally.
  • this has the effect of spreading the fingers or flexible strips defined by the slots and as many contact points are obtained as there are fingers while with conductors made in one piece, there is a risk of having only one point of contact.
  • the connector comprises a first locking body corresponding to the male part cooperating with a second locking body corresponding to the female part, said locking bodies enveloping the electrical connection bodies and one of said locking bodies being connected by elastic means to the corresponding part of the connector.
  • the connector is seen in the locked position.
  • the male part 2 and the female part 6, of cylindrical shape, are crossed in their center by a first and a second coaxial conductors 4 and 8 respectively.
  • the first conductor 4 comprises in its center a wire 5 surrounded by an insulator 7, itself surrounded by a metal braid 9, the whole being surrounded by an insulating sheath 10.
  • the male part is made integral with the conductor 4 by means of a cable gland 24 surrounding the sheath 10 and coming to be placed at the end of the male part opposite to the female part: the cable gland 24 presses a seal 11 which is supported on the sheath 10 and on the male part 2 ensuring sealing at this end of the connector.
  • a cable gland 26 makes the female part 6 integral with the second conductor 8 and seals by means of the seal 13.
  • the male part comprises a first electrical connection body 12, one end of which 20 can come into contact with a second electrical connection body 14 secured to the female part.
  • the latter comprises two split skirts 16 and 18 between which the end 20 of the body 12 is placed.
  • the contact surface between the first skirt 16 and the first connecting body is larger than the contact surface between the latter and the second skirt 18.
  • the latter being in electrical contact with both the first skirt 16 and the first connecting body 12, it allows stray currents to flow to ground.
  • the contact resistance between this second skirt 18 and the body 12 is significantly greater than the contact resistance between the latter and the outer skirt 16, only a small part of the main current flows through the second skirt 18, which greatly reduces the disturbances induced at the central conductor.
  • the second skirt 18 must be in electrical contact both with the first connecting body 12 and with the second connecting body 14 because if one of its ends was free, it would behave like a antenna and the second skirt would no longer play its role of protective screen.
  • the electrical continuity of the central conductor is ensured in a conventional manner.
  • the wire 5 of the conductor 4 has at its end a male pin to which it is soldered and the central wire of the conductor 8 has at its end a female pin to which it is soldered.
  • the male pin enters the female pin, thus ensuring the electrical continuity necessary for the routing of the signal.
  • Figure 2 schematically shows the connector locking system according to the invention. It can be seen that the male part comprises a first locking body 28 provided with lugs such as 32 which can cooperate with slots such as 34 formed in a second locking body 30 located on the female part.
  • this second locking body 30 is movable relative to a part 40 integral with the female part: elastic means 31, in this case a spring, provide the connection between parts 30 and 40.
  • Locking takes place as follows: a first fixed manipulator 43 (fig. 2) holds the female part by means of the locking body 30. A second manipulator 44 grasps the male part and approaches the female part until the front face 41 of the first locking body 28 comes to bear on the front face 42 of the part 40 by compressing the spring 31. The whole of the female part moves back relative to the locking body 30 which remains fixed (fig 3a and 3b).
  • the male part is given a rotational movement so that the pins 32 penetrate into the slots 34.
  • the shape of these is such that, during this operation, the male part moves back slightly, which allows the spring 31 to relax and apply the front face 42 of the part 40 on the front face 41 of the locking body 28.
  • a circular seal 36 located on the front face 41 of the body 28 seals this level of the connector.
  • the connector according to the invention has many advantages, starting with the ease and speed of locking, which makes it possible to carry out this operation using remote manipulators.
  • the electrical characteristics, tightness and immunity to parasites were the same as those of conventional screw connectors, which allows use in a hazardous, radioactive or corrosive for example.
