Abstract

The invention relates to electrical engineering. The aim of the invention is to increase reliability. Sub spring-loaded plastic springs The elec- trical plates of the plug and socket are made with longitudinal gases, bent to a part of the length, into which the plug pins and the contact elements of the socket are mounted, and the stitches are connected by a connecting element. The plugs and contact elements of the socket are made with a bend that repeats the shape of the slots of dielectric plastics 31 / lk and the socket. To ensure contact between the pins and the contactors, the nut is wrapped. In this case, the plates converge, pressing the pins and contact pins against each other. 4 or

WITH

The invention relates to electrical engineering.

The aim of the invention is to increase reliability.

FIG. 1 shows the plug of the electrical connector; in fig. 2 - socket; in fig. 3 - connecting element in the socket; in fig. 4 - a section along the plane of contact details.

On the bases 1 and 2 of the plug, the rail 3 is fixed, on which the dielectric plates 4 and the cheek 5 of the plug are mounted. Pins 6 are installed between the plates 4 in the grooves. Holes 7 and 8 are made in the cheek 5 and 3 base 2. The sockets 9 and 10 of the socket fix the rail 11, on which the dielectric plates 12 and the guide 13 of the socket are mounted. The orienting pins 14 and 15 are fixed in the base 10 and in the guide 13. Between the plates 12 in the grooves are installed contact elements 16. The connecting element is designed as

the studs 17, the sleeves 18, the cup springs 19, the nuts 20 and the restrictive ring 21. Between the plates 12 are installed lamellar H-shaped springs 22.

The connector plug consists of bases 1 and 2, rigidly interconnected by a rail 3 on which a set of plates 4 and a cheek 5 are placed. Between the plates 4 are placed pins 6 representing plates having a stepped bend. In the plates 4, on the junction surfaces, longitudinal grooves and fixing ledges are made in the form of samples and protrusions of the mother / ala, corresponding in shape to pins 6 6 and г to a friend.

each other and the contact elements 16 of the sample and the protrusions, placed the contact elements 16, similar in shape to the pin m 6 plug. Between the plates 4 plugs and 12 sockets in special recesses are placed lamellar H-shaped springs 22. They allow you to withstand a constant gap between the plates to the uncompressed state will connect the PLN. The connecting element is placed in the socket and consists of a stud 17, mounted in the base 10, the hook 18, the cup springs 19, the nut 20 and the restrictive ring 21,

Each stud and contact element with its stepped bend with 90 ° bend angles contacts with the corresponding planes: protrusions on one plate and hollows on the adjacent plate. To ensure relative displacement of adjacent plates, a gap d must be provided (FIG. A) by keeping the distance b in each given plate between the pins of the pin with the adjacent contact elements taking into account the thickness of the contact elements and pins, i.e.

Hence, the need to precisely maintain the angles of inflection of the step of contact elements and pins, namely 90 °. The tolerance at these angles must ensure that the required clearance is maintained (the fit of the stroke type) in order to avoid jamming of the plates with the steps of the contact elements.

The gap D g / vzhdu adjacent plates is selected from the time that when we remove any one contact element of the plate between which it is placed, should be moved apart by an amount that ensures the passage of the stage into the gap between them, i.e.

In addition, the remaining possibility of creating a gap between any other adjacent plates 12 at the same time should exclude the possibility of unauthorized weaning of contact elements between them, i.e.

If this condition is not followed, the connecting element is unattached.

unplanned accidental weaning of any contact may occur; loss of address, requiring additional efforts of the operator to restore it, which causes an additional control not required,

For this, the nut 20 is rotated, which, through the springs 19 and the sleeve 18, transmits the force to the guide 13 and the plate set 12. At the same time, the plate springs 22 are somewhat deformed, and the plates 12 moving closer together and corresponding to them. pressing pins 6 forks of contact elements 16 sockets.

The cup springs 19 prevent nut 20 from being unscrewed. The limiting ring, butt, prevents possible loss of the nut. 20 Movement

the displacement of the guide 13 by means of oriented pins 15 is transmitted to the cheek 5 of the plug, which compresses a set of plates 4 sockets moving along the rail 3. Thus, a coordinated displacement of the contact elements 14 of the socket 14 of the sockets is achieved in pairs when they are crimped

For this, the corresponding pin 6 or contact element 16 is removed from the gap between adjacent plates 4 (12), preliminarily spreading the MX to oastoykie, somewhat higher than the value of the step performed on these parts.
