Definitions
- Electrical connector connectable in water or liquid medium.
- the invention relates to an electrical connector connectable in water or a liquid medium and in particular an electrical connector connectable in seawater.
- EP 0 493 375 and EP 0 251 655 disclose electrical connectors connectable in seawater comprising two expansion chambers of an electrical insulating fluid for pressing the contact portion of the connector to the coupling of the male connector member in the corresponding female member, the outer expansion chamber forming the housing body of the female connector member.
- this deformable outer expansion chamber consists essentially of a wall of elastomeric material whose outer surface can be attacked by solvents, especially in the case of oil drilling.
- the movable shuttle receiving the contact pin of the male element is biased towards the front of the female element by means of a coil spring housed in the rear part of the housing of the shuttle. This arrangement makes the construction complex, especially when it comprises several contact elements and increases the coupling force in proportion to the number of contact elements.
- the invention aims to overcome these drawbacks and proposes an electrical connector connectable in water or a liquid medium, consisting of two complementary connector elements, respectively a male element and a female element intended to be coupled one to the other. another in use in said liquid medium, the male connector member having at least one contact pin protruding from the connector member, and the female connector member having at least one passage opening of the pin for coupling said connector elements, this opening being closed in the non-coupled position by an electric insulating piston element slidably mounted inside the connector element in a rigid and electrically insulating contact chamber, which receives by a zone the contact pin of the male connector element to the coupling, the piston element and the contact pin c or further sealingly engages in the contact chamber by at least two axially separated seals, of which one is located near said opening and the second is located downstream of the contact zone of the pin and the contact chamber relative to the opening, the surface of the piston element between the two seals being connected a chamber filled with electrical insulating fluid, formed inside the connector element, this chamber
- the female connector element can be made of a rigid outer body of non-sensitive material.
- the external deformable flexible wall element which is sensitive to solvents, can instead be exchangeably mounted.
- the mating contact area of the pin and the contact chamber may be formed by a front portion of the contact chamber, receiving in service the conductive active portion of the pin, at the front thereof for example by a set of annular cells clamped on the conductive active portion of the spindle.
- the piston element is mounted forwards towards the edge of the opening of the connector element, advantageously by a spring means disposed at the rear of the piston element around the contact chamber, which is sheathed. of an electrical insulator on all its surface except the zone of contact.
- this spring means can also serve, for example by a common end strand, the recall of other contact chamber pistons elements of other contacts disposed in the connector element, in the case of connectors to several contact.
- the rear part of the contact chamber, not contained by the piston element is also filled with electrical insulating fluid, this by a suitable through hole in its wall.
- a gasket member disposed between the wall of the piston member and the contact chamber is mounted on the periphery of the piston member or at a suitable location of the contact chamber upstream of the piston member. contact area relative to the opening, this to separate the contact area filled with electrical insulating fluid from the contact chamber and prevent any trace of water or external liquid medium in the contact area at the coupling.
- FIG. 1 is a view in axial section of a connector according to the invention in uncoupled position
- Figure 2 is a view similar to Figure 1 showing the connector in the coupled position.
- the electrical connector according to the invention shown in the drawing consists of two complementary connector elements, intended to be coupled in service to each other, respectively a male connector element 1 and a female connector element 13. II has axial symmetry.
- the male connector element 1 is of simplified structure essentially comprising a housing 3 housing axially a cylindrical contact pin 5, fixed projecting forwards and connected to a rear electrical cable 7.
- This pin has a circular section, but can be of another shape, preferably rounded or even polygonal.
- Pin 5 has a conductive portion 9 at the end of its front peripheral surface, the remainder of its surface being sheathed with electrical insulating material January 1.
- the female connector element 13 also comprises a body part or rigid housing 15 of section similar to that of the male element 1, this body part consisting of two parts, respectively before 17 and rear 19, assembled by screws. one to another.
- a contact chamber 21 is mounted axially between said front body portions 17 and rear 19, being connected to a rear electrical conductor cable 23.
- This chamber 21 is mounted on the body portion 19 and on the front face 25 of the body 17, the latter having a front axial circular opening 27, of complementary section to the clearance clearance close to that of the spindle 5.
- This opening 27 is disposed at the front of the chamber 2 1, at a small distance from it. this. It is closed by a piston element or shuttle 29, of cylindrical conformation, mounted to slide axially in the contact chamber 21.
- This insulating piston element 29 electrical is biased forward, to the level of the opening 27 by a rear coil spring 31, connected to the rear end of the piston member 29 and in support on the front face 33 of the rear body portion 19.
- the spring 31 is mounted around the contact chamber 21, its forward strand 35 passing through the contact chamber 21 by an axial lumen 37 of length equal to that of the stroke of the piston element.
- the piston element 29, the zone of contact, the contact chamber 21 at its rear part to the piston and the inside of the front connector part 17 are filled with an insulating electrical fluid, and in particular with electrical insulating oil. which is naturally water-repellent and facilitates sliding of the piston member in the contact chamber.
- the piston element 29 is in communication with its front end portion with the insulating oil circulating in an annular chamber 39 formed in front of the contact chamber 21 in the front face 25 of the connector element, and by its rear part with the insulating oil in the contact chamber 21.
- This contact chamber 21 has an active inner conductive portion 41 in its front portion, which is complementary to that 9 of the pin of the male element, the rest of its surface being coated with an electrical insulating sheath 43.
- the piston element 29 is wiped off from any trace of surrounding fluid as it passes through the bore of the contact chamber 21 by means of two front annular seals 45, 45 'and a rear annular seal 47 mounted on its periphery midway thereof and at the rear of the conductive zone 41.
- the first seal 45 of the front game is fixed on the front face 25 of the connector, the second 45 'being fixed inside the front part of the contact chamber 21.
- the seals 45 'and 47 have the special effect of separating the contact zone from the remainder of the connector thus constituting an additional sealing barrier with respect to any external polluting fluid able to penetrate inside the connector.
- the variation in internal volume of the interior of the female connector element, contained by the insulating oil 49 is compensated by a flexible elastomeric element 51 disposed at the rear of the front body portion 17 and just under its periphery on a small width.
- This flexible element 51 is in the form of a deformable sleeve, secured by its edges respectively to a corresponding recess of the front body portion 17, and a complementary recess of the rear body portion 19.
- This flexible element is in communication with the fluid external 49 (seawater) by means of peripheral holes 53 formed in the wall of the overlying recess 55 of the front body portion 17 and its wall is adapted to deform in this recessed space 55. It can be exchanged in case of wear by disengaging the body parts 17 and 19. The operation of the connector is now described.
- the uncoupling of the connector elements is achieved by a reverse extraction operation at the coupling, the piston element 29 then returning to the level of the opening 27.
