FIELD: chemistry.
SUBSTANCE: group of inventions relates to the field of exploration and production of hydrocarbons, and namely to assembly of the head of the perforator blower. Detonator head assembly comprises a housing having a first end and a second end, as well as a channel extending therebetween, wherein said housing is configured to seal parts located below assembly of the detonator head inside the downhole tool, and is capable of withstanding pressure of at least about 20,000 pounds per square inch (137.9 MPa), and an electrical contact component passing through the housing channel such that at least part of said electrical contact component is configured to rotate about its axis. Electric contact component is made with possibility of electric conductivity and electric signal supply and contains multiple contactors, at least one of which is located with possibility of sliding inside the housing channel.
EFFECT: ensuring integrity of electrical connection.
