The retaining ring is installed with the possibility of rotating and reciprocating movement along the axis of the connector. By means of screws ring attached to the cylindrical body. The end tabs of the retaining ring cooperating with the inclined surface of the base sleeve. The free ends of the screws cooperate with grooves mating with the inclined surfaces of the supporting sleeve. End surface of the cylindrical spring cooperating with retaining ring and the end surface of the base ring.

It is also known "high-Voltage connection of centralized power passenger trains". (Technical description and operating instructions WHO. 364.002 THAT 1994, the technical specifications TU 3456-002-11118762-93).

This contact connection includes a plug (plug), the socket and the locking mechanism of the plug, mounted on top of the housing outlet. The locking mechanism consists of two rotary caps lock and key with the tooth. The first cover has a stop that interacts with a fork. On the axis of rotation of this cover are two slots to lock using the key with the teeth of the two provisions: articulated and dissected (working and the refrigerator is stago). The second cover fixes the position of the lock key.

Known also contact connector: RF patent №2158050, IPC 7 H 01 R 13/625.

Analysis of the known technical solutions showed that the reliability and reliability of connection is achieved due to the complexity of the design, which often leads to increased size, weight connectors and metal consumption.

The maximum number of similar essential features for the prototype accepted contact connector on the RF patent №2158050 priority from 16.06.99, This contact connector includes a socket with the socket, insulator, and a locking mechanism and plug with an insulator. The locking mechanism comprises a cylindrical housing, the collet with teeth, a sleeve with a cylindrical groove and clamp, coil spring, two bayonet connections and reinforced ring with input and output surfaces. Between the insulator of the plug and socket are equipped with shock absorbers.

For joint connector, you must raise the sleeve up and rotate around the axis to lock it in position so that the screws bayonet connections came into horizontal sections of the grooves. Then insert the plug into the plug casing and push it until that reinforced the ring went into the collet. Then turn the sleeve in the opposite direction. Under the action of the spring sleeve SDA is again down and lock the teeth of the collet, hold the plug in the articulated position, and the damper in pojetom.

For dissection of the connector need to lock the sleeve in its upper position and pull out the plug from the housing outlet.

However, the presence of the locking mechanism of the prototype gripper reduces its reliability, as the collet is complicated to manufacture. Constructive and technological features of manufacturing collets can cause damage to her teeth during operation. In addition, the entire locking mechanism has a considerable size and weight, which increases the flow of metal in the manufacture.

The technical task to be solved by the invention is the creation of a design with a simplified locking mechanism. When implementing this invention may be obtained from the technical result consists in increasing the reliability, reduced size, weight and cost. The totality of the claimed essential features ensures the achievement of a technical result.

As a prototype, contact the connector includes a receptacle housing, insulator, shock absorber and locking mechanism and plug reinforced in the insulator ring.

Unlike the prototype, the locking mechanism includes a housing, ending with a threaded sleeve with a cylindrical surface, with collar, with the inner and outer cut is the means the ring collar and scalloped grooves, a nut and a reinforced ring tabs. When this sleeve internal thread connected to the housing, and at its cylindrical surface supported on the collar is a ring that interacts with its collar with the collar sleeve. On the outer threaded bushing screw nut, limiting ring from vertical movement. Ring their slots (at least two) interacts with the tabs reinforced rings and the grooves include a vertical portion with a conical extension and horizontal ledge.

Listed essential characteristics that distinguish the proposed solution from the known, have been identified in other technical solutions in the analysis of the art and, therefore, are new. The claimed technical solution involves an inventive step.

The essence of the invention illustrated by the drawing, which shows a General view of the proposed electrical contact of the connector.

The technical result is ensured by design.

Contact connector as the prototype contains the socket 1 with a housing 2, an insulator 3, the shock absorber 4 and the locking mechanism and the plug 5 with reinforced ring 6 and the insulator 7.

Unlike the prototype, the locking mechanism of the socket 1 is provided with a sleeve 8, screw on the housing 2 with an external thread on the end is. The sleeve 8 has a cylindrical surface with the collar, as well as external and internal screw threads. On the cylindrical surface of the bushing 8 is a ring 9 with a collar that interacts with the clamp sleeve 8 and at least two shaped grooves 10 having a vertical portion with a conical extension 11 and the horizontal with the ledge 12. On the outer thread of the sleeve 8 with a focus in the end of the cylindrical surface of the screw nut 13, which provides a minimum clearance between it and the outer end surface of the ring 9 and the free rotation of the ring 9. Reinforced in the insulator 7 plug ring 6 has projections which cooperate with the slots 10. The number of tabs equal to the number of grooves.

In the present invention the coupling plug 5 plug 1 is as follows. The insulator 7 of the plug 5 to be inserted into the housing 2, by rotation of the ring 9 to be aligned vertical slots with the tabs of the ring 6 and the promotion of the fork up to enter the notches of the ring 6 in the upper part of the vertical grooves, clutching at the absorber 4. Then by rotation of the ring 9 to enter the notches of the ring 6 in the horizontal grooves for ledges 12. The articulated connector, and the shock absorber 4 is compressed between the insulators 3 and 7 and their opposition seeks to push the plug down, preventing thereby to turn the protrusions of the ring 6 relative to the ring 9. Thus there is mutual fixez the I from the reversal of the rings 6 and 9 relative to each other. Still fixing the articulated position of the connector.

The dismemberment of the connector is carried out by application to the fork 5 of the vertical force and the simultaneous rotation of the ring 9 to the tabs of the ring 6 with the vertical grooves of the ring 9. Then plug freely pulled out from the housing outlet.

The processes of articulation and dismemberment for its convenience and speed are not inferior to the prototype. Reliability above as excluded collet. Reduced dimensions while reducing the quantity and sizes included in the design details. Also reduced the weight of the connector and the consumption of metal.

The factory produced designs offer contact connector. Health check of the locking mechanism in the laboratory showed the correctness of the chosen design and the reliability of its operation at 1000-fold articulation and dismemberment of plugs, sockets and the impact of mechanical stress on the articulated connector.

Contact the connector containing receptacle housing, insulator, shock absorber and locking mechanism and plug with reinforced insulator ring, wherein the locking mechanism is provided with a sleeve with a cylindrical surface, with collar, with inner and outer threads, a ring with a collar and a figured grooves, a nut and a reinforced ring tabs, etc is this sleeve internal thread connected to the housing, end of which is threaded, and on its cylindrical surface is a ring, interacting with his collar with collar sleeve, and figured the ring grooves have a vertical portion with a conical extension and horizontal ledge, and a nut mounted on the outside of the threaded sleeve with a focus in the face of its cylindrical surface and limits the ring from vertical movement, while the tabs reinforced ring plug interact with scalloped ring grooves of the socket.
