Description
При малом диаметре жилы микропроволоки зачистка ее концов от стекл нной изол ции затрудн етс и даже становитс невозможной, так как нри этом конец жилы обламываетс вместе с изол цией. Известные же способы присоединени токоотвода к обмотке из микропроволоки в стекл нной изол ции без сн ти последней, не обеспечивают надежного электрического контакта.With a small diameter of the microwire core, stripping its ends from the glass insulation is difficult and even impossible because the end of the core breaks off along with the insulation. The well-known methods of connecting the current lead to the winding of the microwire in glass insulation without removing the latter, do not provide reliable electrical contact.
Дл устранени этого недостатка предлагаетс , не снима изол ции с микропроволоки, гальваническим путем осаждать на ее торце металл, к которому затем посредством гальванизации или пайки присоедин ть токоотвод.To eliminate this drawback, it is proposed not to remove the insulation from the microwire by electroplating to deposit metal at its end, to which then a current lead can be attached by galvanizing or soldering.
Дл осаждени микроскопического медного шарика на торце микропроволоки один конец обмотки из микропроволоки, плотно соприкасающийс с токоотводом, погружаетс в электролитическую ванну с медным электродом, присоединенным к положительному полюсу источника тока. Другой конец обмотки погружаетс в вспомогательную ванну с электролитом, присоединенным к отрицательному полюсу того же источника . Таким путем на торце проволоки осаждаетс микроскопический медный шарик, соединение которого с токоотводом производитс гальваническим путем или посредством пайки.To deposit a microscopic copper ball at the end of the microwire, one end of the microwire winding, which is in close contact with the current lead, is immersed in an electrolytic bath with a copper electrode connected to the positive pole of the current source. The other end of the winding is immersed in an auxiliary bath with electrolyte attached to the negative pole of the same source. In this way, a microscopic copper ball is deposited at the end of the wire, the connection of which with the current lead is made by electroplating or by soldering.
На чертеже, схематически изображающем устройство дл осуществлени предлагаемого способа, прин ты следующие обозначени : / - гальваническа ванна с медным электродом 2; 3 - вспомогательна ванна; 4 - обмотка из микропроволоки в стекл нной изол ции; 5 - конец обмотки; 6 - токоотвод.In the drawing, schematically depicting a device for carrying out the proposed method, the following symbols are adopted: / - galvanic bath with copper electrode 2; 3 - auxiliary bath; 4 - microwire winding in glass insulation; 5 - the end of the winding; 6 - current lead.
При присоединении медного электрода 2 к положительному полюсу источника тока на конце обмотки микропроволоки, наход щемс в ванне 1, осаждаетс электролитическа медь.When the copper electrode 2 is connected to the positive pole of the current source, electrolytic copper is deposited at the end of the microwire winding in bath 1.
После осаждени на торце микропроволоки металла в виде микроскопического щарика размыкают электрическую цепь и присоедин ют токоотвод, на котором лежит конец проволоки с осажденным щариком, к отрицательному полюсу источника тока. При этом медь из электролиAfter deposition at the end of the metal microwire in the form of a microscopic ball, an electrical circuit is opened and a current lead, on which the end of the wire with the deposited ball lies, is attached to the negative pole of the current source. In this case, the copper from the electrolytes
