Description

Предлагаемый герметичный кабельный наконечник относитс  к известному типу наконечников дл  одножильных кабелей с нагревостойкой изол цией.The proposed sealed cable lug is of the known type of lugs for single core cables with heat-resistant insulation.

Подобно известным наконечникам он состоит из керамического проходного изол тора и припаиваемых к жиле и оболочке трубчатых вЫВода и хвостовика.Like the well-known tips, it consists of a ceramic bushing and a tubular outlets and a shank soldered to the core and sheath.

В отличие от известных наконечников, в которых плотное соединение металлических деталей с изол тором достигаетс  запрессовкой этих деталей в керамическую массу в процессе изготовлени  наконечника, в предлагаемом «акопечнике указанные трубчатые вывод и хвостовик припаиваютс  к металлизированным участкам наружной поверхности изол тора.In contrast to the known tips, in which a tight connection of metal parts with an insulator is achieved by pressing these parts into a ceramic mass during the manufacture of the tip, in the proposed baking chamber, said tubular leads and shank are soldered to the metallized areas of the outer surface of the insulator.

Така  конструкци  в услови х работы кабел , характеризующа с  повышенной влажностью и резкими изменени ми температуры (в пределах от О до 430-480°), обеспечивает большую герметичность и механическую прочность кабельного наконечника.Such a structure in the conditions of cable operation, characterized by high humidity and abrupt temperature changes (ranging from 0 to 430-480 °), provides greater tightness and mechanical strength of the cable lug.

Изол тор изготовл етс  методом гор чего лить  из высокочастотной стеатитовой массы с температурой обжига 1200-1230°. В местах соединени  с металлической арматурой изол тор металлизируетс  железосодержашей пастой состава: железа карбонильного--59%, окиси меди-32%, керамического спека-9%.The insulator is made by hot casting from a high-frequency steatite mass with a firing temperature of 1200-1230 °. At the joints with metal reinforcement, the insulator is metallized with iron-containing paste of the composition: carbonyl iron — 59%, copper oxide — 32%, ceramic speca — 9%.

Металлический колпачок и хвостовик после обезжиривани  и травлени  серебр тс  в местах, подлежаших соединению с металлизированным изол тором, с жилой и с оболочкой кабел . Серебрение ведетс  в водородной среде при температуре 1020° со скоростью нагрева и охлаждени  3,5°/мин. и выдержкой в течение 10 мин., .The metal cap and shank after degreasing and pickling are silver in places to be connected with the metallized insulator, with the core and with the cable sheath. Silvering is conducted in a hydrogen environment at a temperature of 1020 ° C with a heating and cooling rate of 3.5 ° / min. and holding for 10 minutes.

Изготовленные таким путем изол тор, металлический колпачок и хвостовик собираютс  в узел и спаиваютс . Дл  пайки примен етс  серебр номедный припой с температурой плавлени  779°. Пайка ведетс  в среде водорода при температуре 780° и выдержке 1,5-2,0 мин со скоростью  агрева и охлаждени  20°/мин.The insulator, metal cap and shank thus fabricated are assembled into a knot and soldered. Silver solder with a melting point of 779 ° is used for soldering. Brazing is carried out in a hydrogen environment at a temperature of 780 ° and a shutter speed of 1.5-2.0 minutes at a rate of aggro and cooling of 20 ° / min.
