Description

The invention relates to electrical engineering, in particular to terminating flat ribbon cables from double-shielded wires into electrical connectors, and can be used to connect shielded electrical circuits.

The essence of the invention lies in the fact that the wires with double shields of the ribbon cable are cut and fixed on the cover of the connector housing, the outer screens are split into screen plates mounted on the cover. The internal screens are arranged on a screen ring isolated from the housing and the cover, while the wiring harness passes inside the screen ring. The body of the electrical connector is made

combined - from metal and non-metal parts. The external screens are electrically connected to the metal part of the housing through racks that are mounted rigidly on the lid, on the other hand the racks abut against the metal part of the housing, and the housing is stepped. A sleeve with a screen ring is installed on the racks.

The invention is illustrated in the drawing.

The electrical connector consists of a block plug 1 installed in the housing 2, which is made combined - the upper part, where the plug 1 is installed, is made of metal, the lower part is made of

plastics. The bottom of the housing 2 is closed by a cover 3, on which a flat cable 4 is fixed using the clamping plate 5. The wires then pass through the screen plate 6, onto which the outer screens of the wires are soldered. The inner screens of the wires are soldered to a screen ring 7, pressed into a sleeve 8 made of a dielectric. The sleeve is mounted on spring struts 9, which are rigidly fixed to the cover 3, on the other side of the strut abut against a ledge made in the metal part of the housing, thus, the outer shields of the wires are electrically connected to the metal part of the housing, since the shield plate 6 is also rigidly connected with the cover 3. It should be noted that the electrical connection of the outer shields of the wires is required with that part of the housing on which the plug 1 is mounted directly, and communication with the metal cover is not provided complies with requirements for protection against interference. The inner screens of the wires, which are wired to the screen ring, are then brought out by wire 10 to the connector pin. Since the shield ring 1 is isolated from the housing, this provides electrical isolation of the inner and outer shields of the wires from each other. The plug 1 in the housing 2 is secured with a crimp sleeve 11 and a support sleeve 12 made of an alloy with thermomechanical memory.

The assembly of the electrical connector is as follows.

A flat cable 4 is fixed on the lid 3, the wires are passed through the screen plate 6, onto which the outer screens of the wires are soldered. Next, the wires are formed into a round bundle and passed into the inner hole of the sleeve 8, at the outlet of the sleeve 8, the internal screens are soldered to the ring 7. Then, the cover on the screws is installed in the housing 2, soldered

on the plug 1, then the plug 1 is mounted and secured to the housing using the crimp sleeve 11 and the support sleeve 12, made of an alloy with thermomechanical

in memory. To seal the connector, the entire internal cavity of the housing is filled with a compound (not shown).

The use of the proposed electrical connector will ensure wiring

internal and external screens with a metal part of the housing and to simplify the installation of wires electrically disconnected from each other, to provide electrical connection between the external screens and the metal part

enclosures and simplify installation.
