Abstract
A downhole electromagnetic device includes an antenna wire placed on or at a tool body, a cavity in the tool body having a cavity pressure smaller than a downhole fluid pressure, and an electronic circuit disposed in the cavity. The antenna wire includes an electrical conductor, and an insulator configured to be exposed to a downhole fluid. The device includes an electrical connector connected to an end of the antenna wire, a sealing element configured to seal the connector from the downhole fluid, the sealing element contacting an inner surface of the connector and an outer surface of the insulator, and a first support member configured to support a load applied on the connector by the antenna wire. The connector provides electrical contact between the antenna wire and the electronic circuit, and the load is caused by a differential pressure defined by the downhole fluid pressure and the cavity pressure.
