Abstract

The invention relates to electrical engineering. The aim of the invention is to expand the operational capabilities of the connector by increasing the range of diameters of the connecting wires. The connector has a housing 1, a contact sleeve 7 with notches 8 forming tabs with spring parts 10 and pressure parts 11, and clamping elements in the form of sleeves 14 with crimping elements formed by petals, on the inner surface of which gear projections 17 are made, and on the outer - annular protrusions 18. The housing 1 is made elastic. The sleeve 7, placed in the cavity 4 of the housing 1, is made by stamping from a sheet of elastic metal with the subsequent formation of a cylindrical surface with a gap between the edges. Between the outer surface of the sleeve 7 and the inner surface of the housing 1 is installed sleeve 14. The clamping part 11

prior to the penetration of the crimping elements 15 into the cavity 4, the insertion of the first clamping sleeve 14 is facilitated by the presence of bevels and the auxiliary pin 3 with the locking pin 2, which create the necessary conditions for centering the sleeve 7 along the axis of the connecting device at any spatial location of the latter, and the accessibility the second clamping sleeve 14 is provided by inserting first. The wiring to the connecting device can be done both alternately and simultaneously. Each of the wires 19 through the open end of the squeezing element 15 is inserted into the sleeve 7 until it stops in the locking pin 2.

The clamping sleeve 14 is pushed into the housing 1. The interaction of the spring parts 10 first with bevels and then with the inner surface of the clamping sleeve 14 forces the pressing parts 11 of the legs 9 to mechanically act on the core 21, ensuring reliable electrical contact cavity 4 with the outer surface of the crimping elements 15 causes compression of the petals 16 around the wire 19 with the transfer of mechanical action due to the elasticity of the housing 1 through the protrusions 17 to the insulation and provide thereby ensuring reliable mechanical fastening of the wire 19. The movement of the clamping cylinder continues until the protrusions 18, interacting with the bevels 5, expand the front part of the housing 1 and then engage with the annular groove 6, which prevents the clamping bush 14 of cavity 4. It should be noted that the magnitude of the mechanical action of the clamping parts 11 of the tabs 9 on the wire 19 is sufficient to use a connector for mounting the wires 19, the insulation 20 of which is not previously removed, provided that the edges of the clamping portions 11 are pointed.

The device allows to expand the operational capabilities by giving it the ability to connect the wires (pins, contacts, etc.) of varying sections, the range of diameters of which is defined as d + Ј, d, where Ј - the value is equal to the foot movement from touching the foot from contact with zero impact on the core to a position that provides a reliable electrical connection
