Claims (9)

1. Устройство для обеспечения соединения между двумя металлическими частями для получения диполя, образующего антенну в бурильной колонне, обсадных трубах или системе труб, отличающееся тем, что оно включает первый металлический элемент (1), имеющий охватывающую коническую поверхность (2), второй металлический элемент (5), имеющий входящую коническую поверхность (6), в котором, по меньшей мере, одна из двух поверхностей покрыта тонким слоем (12) электрического изолирующего материала и в котором два элемента (1, 5) введены один в другой для обеспечения механического соединения при наличии электрической изоляции.1. Device for providing a connection between two metal parts to obtain a dipole forming an antenna in a drill string, casing or pipe system, characterized in that it includes a first metal element (1) having a female conical surface (2), a second metal element (5) having an incoming conical surface (6), in which at least one of the two surfaces is covered with a thin layer (12) of electrical insulating material and in which two elements (1, 5) are inserted into each other to ensure mechanical connection in the presence of electrical insulation. 2. Устройство по п.1, в котором только второй элемент (5) покрыт вышеуказанным тонким слоем, причем вышеуказанный слой имеет контролируемое состояние поверхности и дополнительно может быть видоизменен. 2. The device according to claim 1, in which only the second element (5) is covered with the aforementioned thin layer, the aforementioned layer having a controlled surface condition and can additionally be modified. 3. Устройство по одному из предшествующих пунктов, в котором вышеуказанный слой имеет толщину 0,1 - 0,5 мм, предпочтительно, 0,2 - 0,4 мм и выполнен из материала типа керамики. 3.

Устройство по одному из предшествующих пунктов, в котором герметизирующие средства (а, b, с; 18; 15) расположены, в основном, на двух краях вышеуказанного тонкого слоя, чтобы предотвратить попадание текучей среды между двумя вышеуказанными коническими поверхностями. 4. The device according to one of the preceding paragraphs, in which the sealing means (a, b, c; 18; 15) are located mainly on the two edges of the aforementioned thin layer to prevent fluid from entering between the two above-mentioned conical surfaces. 5. Устройство по одному из предшествующих пунктов, в котором угол наклона вышеуказанной конической поверхности находится в диапазоне от 1 до 2°. 5. The device according to one of the preceding paragraphs, in which the angle of inclination of the above conical surface is in the range from 1 to 2 °. 6. Устройство по одному из предшествующих пунктов, в котором третий элемент (9) соединен с вышеуказанным вторым элементом (5) и контактирует с вышеуказанным первым элементом (1) через, по меньшей мере, одно электрически изолирующее кольцо (11). 6. The device according to one of the preceding paragraphs, in which the third element (9) is connected to the above second element (5) and is in contact with the above first element (1) through at least one electrically insulating ring (11). 7. Устройство по п.6, в котором вышеуказанное кольцо (11) имеет уплотнения (а, b, с), так что контакт между вышеуказанным первым элементом (1) и вышеуказанным третьим элементом (9) является плотным. 7. The device according to claim 6, in which the above ring (11) has seals (a, b, c), so that the contact between the above first element (1) and the above third element (9) is tight. 8. Устройство по п.6 или 7, в котором вышеуказанное кольцо 11 имеет слой электрически изолирующего материала, расположенного, по меньшей мере, на части поверхностей, которые контактируют с краями 10а и 10b первого (1) и третьего (9) элементов. 8. The device according to claim 6 or 7, in which the aforementioned ring 11 has a layer of electrically insulating material located at least on part of the surfaces that are in contact with the edges 10a and 10b of the first (1) and third (9) elements. 9. Применение данного устройства по одному из предшествующих пунктов в качестве антенны для передачи или приема электромагнитных волн. 9. The use of this device according to one of the preceding paragraphs as an antenna for transmitting or receiving electromagnetic waves.
