Abstract

The invention relates to electrical engineering. The aim of the invention is to increase the effectiveness of protection and reduce the size of the object. The purpose is achieved by the fact that the electrical connector is provided with a safety isolator 17, which, together with the protective disk 11, allows efficient use of jumpers between the poles of 18 isolator 17 and disk 11 to protect the contacts, 3 or o / (L 00 el 05 O 00 Fig. D

Description

The invention relates to electrical engineering, namely to electrical connectors with devices that prevent access to the contacts.

The purpose of the invention is to increase the effectiveness of protection and reduce the size

The figo depicts an electrical connector in the dissected position, a longitudinal section; FIG. 2 is a view along arrow A on a FIG. 3 section of the disk and the safety insulator along the circle O. (FIG. 2) in the scan

The multi-pin electrical connector (figs, 1 and 2) consists of two mating parts: plug 1 and socket 2. Socket 2 is mounted on the wall 3 of the container, and plug 1 is fixed on the docking device 4. Counter parts of the electric connector include housings 5 and 6, each of which contains insulation pads 7 and 8 with contacts: sockets 9 - in block 8 and pins 10 - in block 7о In the case

6 sockets with its contact side are installed with the possibility of limited rotation of the protective disk 11 with through holes 12 intended for passage of the pins 10 to the sockets 9 o The limited rotation of the disk 11 during the articulation of the parts is carried out by a key 13 fixed in a fork 1, which interacts with a figure 14 groove a radial protrusion 15 located .in the cavity 16 of the disk 11. Between the disk 11 and the block

7. In the case 5, a safety insulator 17 is fixed with through holes 18, the diameters of which are identical to the diameters of the contact part of the pins 10. The apertures are aligned with the sockets 9c.

Contacts 9 and 10 are placed in blocks along concentric circles. At each subsequent circle, considered to be the smallest, they are offset from the previous one by an angle. rotation of the disk about (., which is determined by the ratio

In the dismembered position, the disk 11 is spring-loaded along the axis to the isolator 17, by the spring 19 and rotated so that its holes 12 are closed by gaps between the holes 18 in the insulator 17 (Figs. 2 and 3). This position of the disk 11 is limited by the stop radial 5 of the protrusion 20 into the ledge 2 of the housing 5 and is fixed by the spring 19, which also works for torsion. The spring 19 is designed in such a way that the moment of turning of the disk 11 created by it exceeds the moment of friction force arising between the dis-. com and isolator 17.

Multi-pin electrical connector works as follows

Using the docking device 4, the plug 1 makes a forward movement in the direction of the socket 2, the key 13 enters the cavity 16, it

The radial protrusion 15 rotates the disc 1 1 by an angle a. The holes .12 in the disk 11 are aligned with the holes 18 in the isolator -17 and pin. Ri 10 freely passes to nested contacts 9

When dismembering the key 13 comes out of the cavity 16 of the disk 11, which is due to the moment given by the spring

Qn, 19, is rotated up to the stop of the protrusion 20 to the step 21, Tov, the disk 11 returns to its original position.

The proposed electric connector, in comparison with the prototype, is additionally equipped with a safety insulator, which, together with a protective disk, makes it possible to effectively use jumpers.
