BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a cable connector for electrical conductors in humid and underwater environments as set forth in the preamble of claim.

The current electrical connection means allow the connection and disconnection of two cables in an environment which cannot exceed a relative humidity of 60-70%. All of these bodies are based on the assembly of two units with insulating housings. There is a locking system for fixing the two units when the electrical connection is obtained. For special applications, e.g. In environments with a relative humidity of 100%, the water is evacuated from the outlet, but it has been found that the use of fats or the like requires an additional working phase.

The present invention eliminates these drawbacks and provides a coupling means for cables with external conductor ring type electrical conductors which allow a coupling in very humid environments, even under water.

This object is achieved according to the invention by the characterizing part of the claim, it being noted that a coupling means comprising an insulating block which is displaceable during screwing of the ring is known from US Patent No. 3,778,092 and that a coupling means with conductive bushings between the connectors is known from British Pat.

The invention will be explained in more detail in connection with the drawing, in which fig. 1 is a longitudinal sectional view of the coupling member prior to coupling; FIG. 2 is a sectional view of the locking system of the two parts of the member; and FIG. 3 is a longitudinal section of the member in the coupled position.

The body comprises two parts A and B, which are to be connected. The part A comprises a cylindrical insulating part 1 with two insulating casings 2, which are passed by the contact pin 3, which protrudes from the casings 2, the whole being arranged in a casing with tubular form, and a coupling ring 4, threaded internally and can rotate, and the portion 5, which is on the side with the pins 3 and which is not threaded, comprises an inner groove 6 with a circular cross-section and extending over the entire periphery.

The portion B also comprises a cylindrical insulating portion 7 with two insulating sleeves 8 passed by the contact pin 9 protruding from the casings 8 by a length greater than the length by which the pin legs 3 protrude from the casings 2. insulating block 7 is disposed in the interior of a casing 10 of tubular shape and such that when the parts A and B are positioned against each other, the end 11 of the portion 10 abutting against the ring 4, the respective pins 3 and 9 will face each other with as little distance as possible. In the interior of the part 10 is a slider 12 of tubular shape and longitudinal movement, the end of which opposite the part A is threaded externally for connection with the ring 4 on the part A.

Inside the slider 12 is an insulating block 14 of cylindrical shape which is passed longitudinally by perforations 15, the portion 16 of which is located at the site of the insulating block 7 having sufficient diameter and length to accommodate the insulating sleeves. 8, when the member is not coupled and whose portion 17 has a diameter equal to the diameter of the pins 9 and 3. The perforations 15 are also provided with contact bushings 18 having an internal diameter equal to the diameter of the portion 17 and a length of one. slightly smaller than the length of the portion 17. The end of the portion 17 at the socket legs 3 is provided with an elastic lip to closely fit the diameter of the perforation 15 to the diameter of the socket leg 3 and to the diameter of the insulating sleeve 2. The end of the perforations 15 opposite the portion 16 is also provided with an elastic lip for adapting the inner diameter to the diameter of the insulating sleeve 8.

Slider 12 is slightly ahead of its portion 13 provided with an annular recess 19, wherein there is a ring 20 having an inclined surface at each end adjacent to portion 13 and with an axial clearance. The portion 10 is provided with holes 22 distributed along the periphery of the side facing the portion A and containing balls 21.

The slider 12 and the part 10 are provided with holes for securing the circulation of the water during the coupling and disengagement phases.

The member functions as follows: Parties A and B are brought into contact with each other, and the part 10 abuts the coupling ring 4. The pins 3 and 9 are in contact with each other. When turning the ring 4, the slider 12 is pulled toward the part A at its end 13, the thread of which engages the thread of the ring 4.

The slider 12 carries the insulating block 14 in its translational movement, and it slides on the connector legs 9 and then moves into the connector legs 3 and on the insulating sleeve 2 on the connector legs 3. At the beginning of the translation movement of the slider 12, the balls located in the recesses 21 in the portion 10 and abutting against the inclined surface of the ring 20, push this ring 20 in for impact and then slide on the largest diameter part. As they do this, they come to abutment in the circular groove 6 of part 4 and unite the two parties.

To disengage the member, rotate the ring 4 in the opposite direction. The balls will come into contact with the smallest diameter portion of the ring 20, thereby screwing up the member. The slider then slides against the insulating block 7 and is released from the pins 3. When the parts 4 and 13 are unscrewed from the threads, the parts A and B can be separated.
