The invention relates to the field of electrical engineering and can be used in devices that exclude, under conditions of vibration, shock and other loads, the spontaneous segmentation of electrical connectors, the counter parts of which are connected by a tension nut.

The purpose of the invention is to increase reliability.

Fig. 1 shows an electrical connector with a coupling nut connecting unit with a housing of one of its counter parts, a general view. in the cut; in fig. 2 shows section A-A in FIG. 1 (the position of the locking elements at the moment of articulation of the counter parts of the electrical connector); in fig. 3 - the same f-position of the locking elements at the moment of dismemberment of the counter parts of the electrical connector) j in FIG. 4 - node I in figure 1

The joint of the self-locking collapsible nut with the housing of the electrical connector contains the fastening nut 2 mounted on the housing 1 of the connector part of the connector, which interacts with the threading part with the threaded surface of the Body

sa 3 plug connectors, locking elements in the form of balls 4, locking elements in the form of tape corrugated springs 5 and 6, located respectively in the annular grooves 7 and 8 of the housing 1 and the lock nut 2 so that the locking element 5 is covered with balls 4, and the fixing element 6 covers the balls 4. The corrugations of the 9 ribbon przgzhin 5 and 6

located in the gap between two adjacent balls 4. The end sections 10 and. 11, respectively, of the springs 5 and 6 are fixedly mounted on the parts matched with the corresponding springs: housing 1 and the lock nut 2. The other end sections 12 and 13 are bent and arranged in the figured grooves 14 and 15 of the housing 1 of the nut 2. Direction from the fixed end 10 (11) to the bent 12 (13) of each fixing element coincides with the direction of rotation of the tightening nut 2 when the coupling parts of the electrical connector are connected.

To assemble the joint assembly, the belt corrugated springs 5 and 6 are allowed with end sections 10 and 11 through the shaped grooves 14 and 15. in the case

1, nuts 2, respectively, in their annular grooves 7 and 8, and fixing the end sections 10 and 11, respectively, in the body of the housing 1 and the clamping nut 2. Then install the clamping nut 2 on the housing 1 so that the annular grooves 7 and 8 form an annular cavity. Further through the hole in the nut

2 Fill the annular cavity with balls 4 and close the opening with screw 16. The assembly is assembled.

The junction works as follows.

The articulation of the counter parts of the electrical connector is carried out by turning the tension nut clockwise (Fig. 2), which interacts with the threaded surface of the housing 3. Together with the tension nut 2, the locking element 6 located in its ring groove, the corrugations of which, interacting with balls 4, tend to unbend, the ribbon spring is pulled out at the same time, and its end portion 13 moves in the shaped groove 15 in the direction of rotation. The locking element 5, located in the annular groove of the housing 1, interacting with the balls 4, works in the same way, and the balls themselves click - to fall into the interglome spacing of the locking elements (belt corrugated springs) 5 and 6.

In the articulated position, the balls 4, together with tape corrugated springs 5 and 6, fulfill the role of rigid locks that prevent the electrical connector from being used in conditions of increased vibrations, impacts, etc. spontaneous dismemberment of its response parts.

When disassembling the electrical connector, the clamping nut is rotated counterclockwise (Fig. 3). The corrugations of the fixing element 6, interacting with the balls 4, tend to unbend, but the balls 4 push the fixing element 6 to the opposite side, i.e. from the loose end 13 to the fixed end 11. When part 17 of the loose end portion 1 ka 13 is folded, the abutment 18 of the shaped groove 15 abuts, the movement of the fixing element 6 is stopped. lUnpuKH 4 abutted in tons of fixing ed. cop. A similar process took place. Dit and with locking element 5.

This prevents self-unscrewing.

tightening nut 2 and separating from

parts of the electrical connector.

With the application of a load of the gum 4 sufficient for rotation of the clamping nut 2, the locking elements 5 and 6 are clicked in the corrugations of the locking elements, the process of splitting is performed.

Thus, in comparison with the known invention, the invention makes it possible to increase the reliability of fixing the articulated position of the response parts of the electrical connector in conditions of increased vibrations, shocks, etc., to simplify the design.
