Abstract

The invention relates to electrical engineering. The aim of the invention is to increase the reliability of the electrical connection. The Z-shaped levers 19 are fastened with the ears 21 to the housing of the socket 1. In the slots of the end 20, the nuts of the spherical shape 18 are installed with the possibility of rotation and linear movement. Screws 10 are screwed into nuts 18, gears 15 are fixed at the upper ends. Gears 15, the engagement with gear 27, through ends 25 of levers 19 interact with annular protrusion 26 of fork 2. When gear 15 rotates, screws 10 are screwed into nuts 18 and lowering the ends of the 20 arms 19. In this case, the ends 25 are engaged with the annular protrusion of the fork. 8 il.

The invention relates to electrical engineering and can be used in the electrical and radio engineering industry, especially in products, where, due to the frequent repetition of the operations of coupling and dismemberment of connectors, cap nuts made of aluminum alloys are quickly degraded.

The aim of the invention is to increase the reliability of the electrical connection.

FIG. 1 shows an electrical connector; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section B-B in FIG. in fig.i - section bb in fig. one; in fig. 5-8 - electrical connector elements.

A cylindrical casing 3 is fastened to the socket 1 and the plug 2 from above by a threaded connection, and four studs k are screwed around the perimeter, for example through 90 °, on which the support ring 6 is fixed with nuts 5,

Socket 1 and plug 2 have contact elements 7.

Between each two adjacent studs 4 (symmetrically) through the holes 8 and 9, drilled, respectively, on the support ring 6 and on the housing of the socket 1, four screws 10 pass, at the upper ends of which there are annular flanges 11, terminating in shanks 12g which in cross section have a square with threaded holes 13 to which gears 15 with cylindrical protrusions 16 are fixed with screws 14, and the lower threaded surfaces 17 interact with floating nuts 18 located in the horizontal ends of the Z-shaped arms 19. Float An enclosing nut 18 is installed in a groove on the upper horizontal end 20, in the middle of which there is an eye 21 with a hole 22 for fastening in the right-moule opening 23 of the socket 1 with the corresponding axes. Lower horse

25 levers 19 performs the role of a hook for the annular protrusion 26 of the fork 2.

The annular beads 11 on the screws 10 are designed to prevent their axial movement upwards.

The cylindrical protrusions 16 on the gears 15 are designed to prevent axial movement of the screws 10 downwards, as well as to create a free space between the support ring 6 of the gear-gear 27.

The shanks 12 of the screws 10 are designed to transmit rotational motion from the gears 15 to the screws 10. The screws} k prevent the gears 15 from falling out from the shanks 12. Key-gear 27 interacts with the gears 15, which is closed by a cover 28 and fixed by screws 29 .

Before the construction is brought into a working state, its initial position should be the following: on the case of the socket 1, the studs k are screwed around the perimeter, on which the support ring 6 is put on and fixed with nuts 5.

Further assembly occurs in the following sequence. The key-gear 27 is mounted on the restrictive ring 6 so that the side covered by the cover 28, is on top. The screws 10 are successively threaded with the ends 17: the holes 9 of the socket 1 and 2-3 turns are screwed into the nuts 18 of the levers 19, then with the warp ends, having passed their cut holes 8 on the support ring 6, gears 15 are mounted on the shanks 12, the gears 15 are mounted on the shanks 12 with key gear 27 and fastening them with screws 1.

Levers 19 with 2k axles behind the holes 22 of the ears 2 | mounted in the sockets 2k located in the rectangular openings 23 of the socket 1. The key-gear 27 is closed by the cover 28 and secured by the screws 29.

The locking device of the electrical connector works as follows.

Before installing socket 1 into the plug 2 using the gear wheel 27, the levers 19 must be set to the Open position. For this purpose, gear wrench 27 is rotated clockwise. In this case, the gears 15, interacting with it, transmit the rotational movement to the screws 10, which are screwed into the floating nuts 18 and the upper end 20 of the lever 19 upwards, and therefore, the lower arm 25 from the housing of the socket 1.

This initial state ensures that the socket 1 and the plug 2 dock. The socket 1 is installed in the plug 2 and, rotating the gear wrench 27 counterclockwise, transmit the rotational movement to the screws 10, which, unscrewing from the floating nuts 18, feed the upper ends (shoulders) 20 levers 19 down, and the lower ends (shoulders) 25 - for engagement with the annular protrusion 26 of the fork 2.

The disengagement of the levers 19 from the annular protrusion 26 is performed in the reverse case of the outlet, and the other sequence, i.e. the pro-horizontal ends of the Z-shaped rings appear when the key-gears of the chagas rotate and interact with the ring 27 in a clockwise direction. fork protrusion.
