The invention relates to electrical engineering and can be used in the drilling and operation of directional and horizontal oil and gas wells.

Famous underwater connector A.S. 721874 (publ. 15.03.80), consisting of plug and socket, which includes made of elastic insulating material of the pad response form, facing each other, side surfaces of which are flush with the latter are flat contacts established with a gap along the longitudinal axis of the connector, and strip the fork is made in the form of a Cup having a cylindrical internal surface and an outer conical, tapering in the direction of the joint, the internal cavity of the Cup filled with liquid or compressed gas.

The disadvantage of this connector is the complexity of the control connection and disconnection, as well as the need for the supply of additional control lines.

Known hermetic electrical connector as 792383 (publ. 30.12.80)containing the plug with pin contacts, housed in the insulator, and the centering sleeve telescopically covering the socket with the slots, the inner cavity of which is filled with insulating liquid and closed by coupling the elastic diaphragm, the node mutual fixation of the plug and socket elements of the angular orientation is AI in the form of a longitudinal groove located therein finger, made in the centering sleeve and one of the parts of the connector, and a current supply, which is provided with a cylindrical part having a weight, which provides the puncture aperture pin on one end of which is fixed a socket, the latter is connected with the conductors, at length placed in the cylindrical part, the node mutual fixation made in the form of still installed on the empty area of the electrical power supply from the side opposite to the outlet of the sleeve, on which hinged pair one shoulder levers pivotally connected with two shoulders arms, one ends of which are interconnected by a spring, while others interact with the annular protrusion made on the inner surface of the centering sleeve while the groove has a lead-in portion and formed on a cylindrical part and a finger in the centering sleeve, and an insulating fluid has a density less than the density of the drilling fluid and the plug insulator is made of a hydrophobic material.

The disadvantage of this solution is the possibility of ingress of drilling fluid into the internal cavity of the connector that leads to the violation of the contact of the connected parts of the connector, as well as the complexity of the execution of this fixation device for small diameter.

The invention solves the problem of reliable fixation of the cable connector, secure the CSO separation of male and female parts for a given effort.

To achieve the technical result in the cable connector to work in a conductive medium, comprising male and female parts with the fixing unit, the fixing unit is located in the male part of the connector and includes a sleeve, the internal diameter greater than the outer diameter of the nesting portion, the locking elements brought together by the elastic ring and fixed in the ferrule, which is tightened by a spring to the inner ledge of the pin housing part further comprises a rotary valve and its associated lever mounted on the axis.

Distinctive features of the proposed cable connector from the above known closest to him, is that the fixing unit is located in the male part of the connector and includes a sleeve, the internal diameter greater than the outer diameter of the nesting portion, the locking elements brought together by the elastic ring and fixed in the ferrule, which is tightened by a spring to the inner ledge of the pin housing part further comprises a rotary valve and its associated lever mounted on the axis.

Due to the presence of these characteristics of the proposed design ensures reliable fixing of the cable connector, a reliable separation of the male and female parts for a given force applied to the cable when working in mud races of the thief and at a considerable distance from the point of application of effort.

The proposed design is illustrated by drawings, where

figure 1 shows the pin portion of the cable connector

figure 2 shows a cable connector Assembly.

Cable connector consists of a connector pin 1 (figure 1) and female 2 parts (figure 2). The fixing unit is located in the male part of the connector. The fixing unit includes a sleeve 3, the internal diameter greater than the outer diameter of the breeding part 2. A set of locking elements 4, which represent segments having beveled portion inner surface, tight elastic ring 5 and is fixed in the holder 6, which is tightened to the inner ledge of the housing whip part of the spring 7. Male portion of the connector from the input socket part has a special device that prevents the release of contaminants from the walls of the pipe columns inside the connector when driving on cable, with a female part. Pin the part on the input side socket side is a rotary valve 8 and the associated lever 9 mounted on the axle 10. Male portion of the connector is connected with the pipe column. When entering the breeding part in whip it through the lever 9 pushes the valve 8, when it got on her fat dropped out through a lateral groove in the housing pin part. Upon further movement of the breeding part of it passes through the sleeve 3, and then through the fix is the dominant elements, letting socket part in the direction of the pin without much effort due to selection of the stiffness of the elastic ring. Socket part when connecting to whip part is fixed due to the fact that the segments of the locking parts fall into the groove of the female body part.

If necessary, disconnect the cable connector is necessary to pull the cable with a force that exceeds the force of the spring tension that holds the clip with locking elements. When the application of force on the cable greater than the spring force, it will shrink and sleeve, interacting with its end surface with beveled portions of the inner surfaces of the clamping elements will stretch elastic ring, with the locking elements will be released from the annular groove female and release her.

Cable connector for operation in the conductive medium is a key element and technological complex delivery of geophysical instruments downhole during drilling and operation of directional wells, i.e. those where the device cannot simply be lowered downhole on a wireline. The device is delivered downhole on the end of the columns of a flexible tubing, such as tubing, the total number of which is chosen so that they reach the bottom under its own weight. Geophysical instrument soedenjaetsja column pipes through the whip part of the cable connector. After Assembly in a vertical wellbore into the column lower wireline, provided on the end of the nesting part of the cable connector, to connect with the whip part, with the set of electrical contact with the device and the fixation of the contact. The connection can occur in drilling or other solution that fills the hole, and at a considerable distance from the point of application of effort.

Work with the proposed cable connector is as follows.

The logging cable, fitted on the end of the nesting part of the cable connector is lowered into the column to join with the whip part. Socket part when moving inside the column is contaminated to clean up the pollution trapped in the valve, provides a mechanism for otodviganija valve and garbage deposits through a lateral groove in the housing pin part. Upon further movement of the breeding part inside the whip part of it passes through the sleeve and pushes the locking elements brought together by the elastic ring. Simultaneously with achievement of the contact fixing elements fall into the groove of the female body parts, and thus is a reliable fixation of the contact. To disconnect the cable connector to the cable to exert a force greater than the tension force of the spring.

The proposed design is about who has a reliable fixing of the cable connector, and reliable separation of the male and female parts with a small force applied to the cable attached to the end connector, and separation occurs at a distance of 200-500 meters from the effort.

Cable connector for operation in a conductive medium, comprising male and female parts with the fixing unit, wherein the fixing unit, located in the male part of the connector includes a spring-loaded sleeve, the internal diameter greater than the outer diameter of the breeding part, and the locking elements, tight elastic ring and fixed in the ferrule, which is tightened to the inner ledge of the pin housing parts, and the male part from the entrance to her female part further comprises a rotary valve and its associated lever mounted on the axis.
