FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to a drilling tool and can be used in electrical connections of a drill string. In particular, the proposed device for data transmission through the connection of the drill lock, made with the possibility of placing in the wellbore. Device comprises: first data transfer element connected to a first downhole component having a first tool connecting element comprising a first outer surface, recess in the first outer surface extending over the first connecting element of the tool, and pin of the bayonet connection, mounted on the outer surface of the first connecting element of the tool and extending therefrom; and second data element connected to a second downhole component having a second tool connecting element comprising a second outer surface, recess in the second outer surface extending above the second tool connecting element, and groove adapted to receive a bayonet pin of the first tool connecting element. Device also contains many protective covers, each of which contains: outer surface, which is part of a cylinder. First recess of the first connecting element of the tool and the second recess of the second connecting element of the tool are configured to receive a protective casing. First data element contains one of the male element of the coaxial connector and the female element of the coaxial connector, and the second data element comprises another of the male element of the coaxial connector and the female element of the coaxial connector. Each of the female element of the coaxial connector and the male element of the coaxial connector contains a plurality of concentric contacts, many covering concentric contacts are configured to mate with many covered concentric contacts. In this case, the electrical connection between the female element of the coaxial connector and the male element of the coaxial connector is formed during the formation of the drill lock joint by mating the first tool connecting element and the second tool connecting element.
EFFECT: technical result is to reduce the possibility of damage to the electrical connections during assembly, disassembly of the downhole tool and during drilling.
