Изобретение относитс к технике нагрева изделий в сверхвысоковакуумных печах, требующих прогрева кожуха.This invention relates to a technique for heating products in ultra-high vacuum furnaces that require heating of a casing.
Дл обеспечени электрической вакуумноплотной изол ции токоввода от кожуха печи в св зи с необходимостью нагрева последнего нужны керамические изол торы. Известны токовводы , состо щие из металлического ввода, соединенного с сильфоном или жестко соединенного путем пайки с керамическим изол тором .Ceramic insulators are required to provide electrical vacuum insulation of the current lead from the furnace shell due to the need to heat the latter. Current leads are known to consist of a metal lead connected to a bellows or rigidly connected by soldering to a ceramic insulator.
Недостатком этих конструкций вл етс ненадежность соединени и поломка изол тора при монтаже и в случае даже незначительных перекосов.The disadvantage of these structures is the unreliability of the connection and the breakdown of the insulator during installation and in the case of even minor distortions.
С целью устранени этих недостатков, св зь между металлическим вводом и одним концом сильфона выполнена жесткой, а другой конец сильфона жестко св зан с изол тором .In order to eliminate these disadvantages, the connection between the metal lead-in and one end of the bellows is rigid, and the other end of the bellows is rigidly connected to the insulator.
На чертеже изображен токоввод.The drawing shows the current lead.
Токоввод состоит из металлического ввода 1, металлокерамического изол тора 2, сильфона 3, фланца 4 и кольца 5. При монтаже токоввода крепитс на место фланец 4, а затем закрепл етс металлический ввод 1, который благодар наличию сильфона 3 не передает усилий на изол тор 2.The current lead consists of a metal inlet 1, a cermet insulator 2, a bellows 3, a flange 4 and a ring 5. When the current lead is mounted, the flange 4 is fixed in place, and then the metal inlet 1 is fixed, which, due to the bellows 3, does not transmit forces to the insulator 2 .
Предмет изобретени Subject invention
Токоввод дл сверхвысоковакуумных резистивных электропечей, содержащий металлический ввод, св занный с одним концом сильфона , и керамический изол тор, отличающийс тем, что, с целью повышени механической прочности токоввода, св зь ввода с сильфоном выполнена жесткой, а сильфон противоположного конца жестко св зан с изол тором .A current lead for ultrahigh vacuum resistive electric furnaces containing a metal lead connected to one end of the bellows and a ceramic insulator, characterized in that, to increase the mechanical strength of the lead wire, the lead in connection with the bellows is rigid, and the bellow of the opposite end is rigidly connected isolator
