Abstract

1. Переход высокочастотный в загрязненную зону через металлическую стенку защитной конструкции, в частности взрывозащитной камеры (ВЗК), содержащий герметично установленный в стенке металлический корпус, в сквозном отверстии которого герметично закреплен стеклоизолятор, размещенный между двумя изоляторами, через которые проходит центральный электрический проводник, средняя часть длины которого выполнена в виде электропроводного штыря, впаянного в стеклоизолятор, отличающийся тем, что стеклоизолятор закреплен в корпусе при помощи стекла припоечного, в отверстие корпуса через дополнительные изоляторы, размещенные с обеих сторон стеклоизолятора, введен экранирующий проводник, образующий с центральным электрическим проводником коаксиальную пару, средняя часть длины экранирующего проводника выполнена в виде нескольких дополнительных электропроводных штырей, герметично впаянных в стеклоизолятор, причем дополнительные штыри равномерно распределены по окружности относительно центрального штыря, при этом со стороны входа и выхода экранирующий проводник поджат к корпусу при помощи подвижных гаек, выполненных из электроизоляционного материала, на посадочной поверхности корпуса выполнены канавки для установки в них уплотнительных колец.2. Переход высокочастотный по п.1, отличающийся тем, что корпус выполнен из титана.3. Переход высокочастотный по п.1, отличающийся тем, что дополнительные изоляторы и подвижные гайки выполнены из поликарбоната.4. Переход высокочастотный по п.п. 1-3, отличающийся тем, что он выполнен составным из двух равноценных частей, скрепленных по внешним торцам корпусов, снаружи место1. The high-frequency transition to the contaminated area through the metal wall of the protective structure, in particular the explosion-proof chamber (ВЗК), containing a metal enclosure sealed in the wall, in the through hole of which a glass insulator is sealed, located between two insulators through which the central electrical conductor passes, middle part of the length of which is made in the form of an electrically conductive pin soldered into a glass insulator, characterized in that the glass insulator is fixed in the housing using solder glass, a shielding conductor is inserted through additional insulators located on both sides of the glass insulator, forming a coaxial pair with the central electric conductor, the middle part of the shielding conductor is made in the form of several additional electrically conductive pins hermetically soldered into the glass insulator, and the additional pins are uniformly distributed around the circumference relative to the central pin, while the shielding conductor is drawn to To the housing with the help of movable nuts made of electrical insulating material, grooves are made on the landing surface of the housing for installing sealing rings in them. 2. The high-frequency transition according to claim 1, characterized in that the housing is made of titanium. The high-frequency transition according to claim 1, characterized in that the additional insulators and movable nuts are made of polycarbonate. High-frequency transition 1-3, characterized in that it is made up of two parts of equal value, fastened at the outer ends of the buildings, outside the place
