ELECTRIC SIGNAL SPLITTER-RELAY Russian patent published in 2016 - IPC E21B47/12 H04B1/38 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysical research and production wells during drilling. Disclosed is an electric relay divider comprising a composite metal housing with connection threads on both ends, consisting of upper and lower adapters, as well as an intermediate insulation insert located between them, connected by threaded joints, in which separate metal parts are insulated from each other by a dielectric layer. Device also comprises a section of outer coating from dielectric material, a dielectric bushing with a channel for passage of drilling solution and installed inside dielectric bushing electronic unit connected with one contact through metal part to bottom adapter, and other contact to upper adapter. Electronic unit is equipped with transceiver of signals and power supply unit and is placed in additional metal casing, equipped with centralisers, which is installed in channel for passage of drilling solution with possibility of its unobstructed passage, and is fixed to lower adapter by nut with pin, which perform function of electric contact of lower part of metal enclosure of electronic unit with said adapter. Input of electronic circuit is connected to contact pin electric wires, and input of electronic unit in upper part of metal enclosure is connected via wire communication with an electrical connector for connection of response to electronic unit main telemetry system.

EFFECT: broader functional capabilities for transmitting information from any communication channel.
