PAIRED FIELD CABLE Russian patent published in 2023 - IPC H01B11/06 H02G15/18 

FIELD: communication.

SUBSTANCE: field communication cables. The cable 1 contains insulated shielded pairs, including two twisted conductive cores 3, an outer sheath 4 and a connecting half-coupling. The connecting half-coupling has a contact block 6 with a screen pin contact 18 fixed in the center, around which pin contacts of current-carrying conductors are installed in this block. Moreover, the pin contacts are located evenly on a circle, in the center of which there is a screen pin contact. In this case, the current-carrying cores of one pair are connected to diametrically located pin contacts, thereby creating a symmetrical balanced bridge of connections, and the screens of each pair are connected to the mentioned screen pin contact.

EFFECT: increasing the noise immunity of the field cable from the mutual electromagnetic influence of the working circuits of the cable.
