Definitions

  • the invention relates to electrical connectors and more particularly those which are intended to be submerged, for example with submarine cables.
  • an electrical connector essentially comprises two insulating bodies provided with through housings in which are arranged connection elements, such as pins or plugs of the male and / or female type able to cooperate.
  • connection elements such as pins or plugs of the male and / or female type able to cooperate.
  • the object of the invention is to provide a connector with retaining pins, which is easy to machine and / or to manufacture and / or mold and which offers all the desired security by simple means ensuring without weakening the sockets and pins. of connection their maintenance in their respective insulating body and the maintenance of the transverse pins in their position of use.
  • a connector having an insulating body made of rigid material with at least one longitudinal housing having an internal shoulder for stopping a pin or a socket, at least one pin or socket having a first external shoulder which is introduced into a corresponding housing until this first shoulder meets the shoulder of the housing, a transverse breakthrough, a locking pin placed in this transverse breakthrough according to the invention is remarkable in that each pin or socket has opposite the first shoulder, a second shoulder and the transverse breakthrough is arranged so that, after its installation in this transverse breakthrough, the pin is located opposite the second shoulder of each pin or socket and immobilizes the latter by preventing its recoil.
  • Means for retaining the pin housed in the corresponding transverse breakthrough consist of an elastic seal situated around said pin, and the external dimension of which is greater than the internal dimension of said breakthrough.
  • the means for retaining the pin housed in the corresponding transverse breakthrough consist, in addition to or in place of the above elastic joints, by a protective sheath which surrounds each insulating body of waterproof way.
  • each protective sheath extends longitudinally on each insulating body and on the electric cable which penetrates behind them, and preferably, the protective sheath of one of the insulating bodies also extends so as to cover the joint plane in which the end faces of the two insulating bodies of the assembled connector meet at least in part.
  • the protective sheath which is extended beyond the joint plane is shaped in its end part by means of attachment and the insulating body on which it extends has correspondingly on its outer face a cooperating attachment means with that of the sheath.
  • FIGS. 1 and 2 represent, respectively, two sections along two perpendicular planes of the same embodiment of an assembled connector, more particularly suitable for being submerged, for example, at the end of submarine cables and / or on submerged devices.
  • the connector comprises an insulating body 1 in which longitudinal through holes 2,3,4,5 are made.
  • Each breakthrough has substantially at one of its ends, at least one shoulder 6 which implies in an advantageous embodiment that each housing has at least, along its axis, for example 7 for the breakthrough or the housing 3, two valuable sections different, respectively 8 and 9, the passage from one to the other of these two sections providing the desired shoulder 6.
  • the insulating body is made of a rigid material, such as for example a ceramic to have a very long lifespan, several years, in particular in the case of submersible connectors with submarine cables.
  • connection piece 11, 12, 13, 14 made of electrically conductive material, a first end of which constitutes the connection part, which can be a pin 15, but which of course could be a socket, and a second support end 16 of which has a first shoulder 17 complementary to the shoulder 6 of the housing 3, so that when the pin or socket is inserted into its housing, the support end matches in a complementary way keep silent a section of the housing, for example section 9.
  • the first shoulder 17 abuts against the shoulder 6 so as to perfectly define the position of the part relative to the insulating body 1, so that the pin 15, in the example described, emerges from the insulating body of a determined length which will in this case be substantially equal to the value of the depth of the socket with which it is intended to cooperate to ensure the continuity of the transmission of power or electrical information carried by the cables connected to the connector.
  • this first shoulder 17 securely stops the part, spindle or socket, against any tearing force towards the front of the body 1.
  • each pin or socket has a second shoulder 20 opposite the first shoulder 17.
  • These opposite shoulders 17, 20 appear as a reinforcement in this zone of the section of the body 21 of this pin or socket which is by elsewhere markedly less than the section 8 of the housing 3.
  • the insulating body 1 has a transverse breakthrough 22, the axis 24 of which is substantially perpendicular to the axis 23 and has a section determined so that it opens out at least in part in each of the housings 2 to 5. This breakthrough is made in fact in the insulating body 1 so that the envelope of this section passes just behind the second shoulder 20 of each pin defined above.
  • These retention means may be constituted by an elastic seal 41, partially surrounding the pin, for example in a groove 42 and whose outside diameter 43 before it is compressed, is slightly greater than that of section 22 so that when the pin is inserted into the housing 22, the seal can be slightly crushed and that by its natural elasticity, it comes to press against the side wall of the transverse breakthrough and then ensure sufficient pressure force and friction to maintain the pin 30 in place in the breakthrough 22.
  • each pin 30 does not protrude from the outer face 44 of the insulating body 1 in which it is threaded. It is therefore possible to surround each insulating body 1 with a protective sheath 40 and the latter can be tightened enough against this outer face 44 to ensure sealing and prevent any penetration of water.
  • Each protective sheath 40 is long enough also to cover a substantial length of each body 1 as well as a section of the electric cable 45. Thus, each sheath 40 is opposed to the exit from the body 1 of the pin 30 which it surrounds ; one could therefore dispense with the use of the elastic seal 41 described above as a means of retaining the pins 30 in their position of use.
  • an end portion 46 narrowed in a transverse direction of one of the connector bodies penetrates in the other body, which is hollowed out accordingly.
  • the joint plane of the end faces of the two assembled bodies is a broken plane, part of which designated by the reference 47 is adjacent to the external face 44 of the body 1.
  • the sheath 40 which covers the body 1; that of the right half when looking at FIG. 1, in this example, is extended so as to cover the joint plane 47 and to extend beyond the latter, on the body 1, thus ensuring the seal between bodies 1 and 1 '.
  • this same extended sheath 40 ends in a free part shaped as an annular internal hook 48.
  • the body on which this annular hook 48 extends has an annular protuberance 49 which has a first inclined face 49A which facilitates the passage of the hook annular 48 when the two connectors are coupled.
  • the protrusion 49 has a face 49B substantially perpendicular to the body 1 so as to oppose the separation of the two assembled parts.
  • Other complementary attachment means could be provided in correspondence on one body and at the end of the sheath of the other body of the assembled connector.
  • the body 1 can be covered with a protective sealing sheath 40; the latter is suitable when the connector is intended to be associated with submersible cables; in addition it is used to hold the pin permanently in place.
