Selenaaa part 1 contains the mechanism for moving the connectors, made in the form of a bracket 9, in the center of the through part of the cylinder 10, in the wall which made the two slots 11. The cylinder 10 has a card 12 with covering the cylinder 10 by a sleeve 13 with two holes. Part of the bracket 9 is made in the form of a bracket 14. The bracket 14 of the transfer mechanism of the connectors installed the latch open and closed position, made in the shape of the plug 15, the axis of rotation 16 which passes through two holes in the prongs of the fork 15 perpendicular to the longitudinal axis of the fork 15 and through the slot in the bracket 14 perpendicular to its longitudinal plane, and acting contrary to the prongs of the fork 15 part made in the form of glass 17. In the bottom of the nozzle hole, the axis of which coincides with the longitudinal axis of the plug 15, and in the cavity of the Cup 17 is placed a spring-loaded rod 18 mounted for movement along the axis of the Cup 17, at one end of the spring rod 18 is rigidly fixed to the arm 19 and at the other end through the axis of rotation 20 is installed fixing element in the form of roller 21. The spring 22 one end through the roller 21 abuts against the end surface of the bracket 14. In the wall of the Cup 17 is diametrically opposite the groove 23 along its generatrix of the surface in the plane passing through the axis of rotation 20 of the roller 21. In the prongs of the fork 15 is a two groove 24 in a plane coincident with the longitudinal axis of the plug 15, and the inside of the cylinder 10 with the possibility of p is motion along its axis has a cap 25 with the spring 26, which made the hole along the axis perpendicular to the axis of the cap and lying in the plane passing through the longitudinal axis of the slots 11 of the cylinder 10, and is made in the bracket 9 n holes, the axes of the holes of the sleeve 13 and is made in the circuit Board 12 n holes of the housing of the connectors 2 and intersecting the grooves 24 of the fork 15.

The spring 22 one end through the roller 21 located in one of the return grooves 28 or 29 of the bracket 14, rests in its end surface, and the other in the bottom of the Cup 17.

The proposed variant of fixation guaranteed clearance between sochlenenii parts and elements of the alignment axes sochlenennykh parts and their angular position shown in figure 5 and 6, includes the receiving node 30, is fixed in advance on the site, for example on the outer surface of the hull of a spaceship, and set the node 31 to be installed on the receiving node 30.

The receiving node 30 is made in the form of a hollow cylinder, the bottom of which is on a circle of smaller diameter evenly positioned guide pins 32, and around the circumference of the larger diameter ball stops 33, herein the node 31 is made in the form of a hollow cylinder, the bottom of which is made under the guides 32 input cone 34 to grubigstein and socket 35 under the ball stops 33 for precise adjustment, and inside the installed node 31, coaxial connectors 35, secured locks 36.

On one of the locks 36 is fixed to the arm 37, and between the castles connected by rods 38 through the plug 39. Arm 37 mounted for rotation about the axis of one of the locks 36, which is fixed to the handle from the position “open” to the position “closed”.

The device operates as follows.

On the outer surface or remote farm, for example, orbital spacecraft, ground conditions are attached to the receiving nodes 30. Set the node 31 is delivered into orbit, for example, on a cargo spacecraft or apparatus of the type space Shuttle. Set the node 31 is delivered manually by the operator to the receiving node 30. During rendezvous and docking nodes 30 and 31 of the arm 37 of the installed node 31 is locked in position “open”.

When the cart is installed node 31 to the receiving node 30 tolerances for pitch, roll, and yaw sphere, at least one of the guide pins 32 of the receiving node 30, for the internal conical surface of one of the ends of the cones 34, made with the desired geometric sizes for choice errors, set the node 31 and under pressure along the longitudinal axis of the receiving node 30 other areas of the guide pins 32 kasitsiseadistamine internal tapered surfaces of the ends of the cones 34 are installed node 31, resulting in selection bias supply roll and pitch. At a later stage of the dock there is a choice of supply errors in yaw due to the sliding areas of the guide pins 32 on the inner conical surface of the ends of the cones 34 and when the spheres pins 32 from the zone of contact with the surfaces of the cones 34 is contact areas of ball lugs 33 with the inner conical surface of the slots 35. After precise alignment on the inner conical surface 35 nests sphere ball stops 33 are in the area of call inside locks 36.

The final fastening of the set of node 31 is made by turning the knob fixing 37 in the position “closed”, which results in fixation of the guaranteed gap h is set when designing the mechanism for moving the connectors, the combination of axes and angular position between sochlenenii parts of electrical connectors.

The electrical connector is articulated as follows.

The operator pulling the handle 19 of each of the connectors themselves along the axis of the spring rod 18, and the roller 21 mounted on the rod 18 through the axis of rotation 20, comes from the response of the groove 28 of the bracket 14, moves the arm 19 to the fixing roller 21 in the lower position in response groove 29 of the bracket 14. In the process of the transfer arm 19 along the way the overall surface of the bracket 14, the grooves 24 of the fork 15, interacting with the pin 27, move associated them with the sleeve 13 of the Board 12 is fixed on the Board connectors 2 and the cap 25 along the grooves 11 of the cylinder 10, compressing the spring 26, acting as a vibration damper of vibrations toward the mating connector 4. Then there is guaranteed electrical connection of the contact fields 6 and 8, respectively, the housings 5 and 7 sochlenennykh parts 1 and 3. If the roller 21 is in the return groove 29 of the bracket 14, spontaneous separation sochlenennykh parts 1 and 2 is impossible.

For dissection of the connectors 1 and 3, it is necessary to pull the handle 19 on itself along the axis of the spring rod 18, the roller 21 will be released from the response of the groove 29 of the bracket 14, and translate it into the locked position in response to the groove 28 of the bracket 14, and the roller 21 drops in the return groove 28 of the bracket 14.

As a result of use of the claimed invention greatly facilitates the operator's work, under difficult conditions, decreases the time of joining electrical connectors.

This design can be used for docking payloads, for example, to the housing or remote farm orbital spacecraft with the implementation of the maximum number of electrical connections payload with the Board the spacecraft.
