Description

ктрода 3, размещенного внутри токового . Потенциальный электрод 3 выполнен в виде стержн  с цилиндрическим направл ющим буртиком 4 и хвостовиком 5 дл  токосъема, рабоча  часть ег 6 плоска  со скосами и соединена с потенциальным электродом 3 при помощи шарнира 7« Дл  изол ции токовсм го электрода 1 от потенциального 3 в подом ТОКОВОМ; электроде 1 размешена диэлектрическа  втулка 8 (фиг. 1),  в  юшайс  одновременно направл ющей да  буртика 4 потенциального электрода 31 Пружины 9 и Ю служат дл  создани  необходимого усили  прижати  электродов к металлизированному отверстию печатной платы (фиг, 2), причем усилие в момент контактировани , соэдаваемое пружиной 9, в 8-10 раз больше усили  пружины 10. Изол ционна  шайба 11  вл етс  упфом дл  пружины Юн направл ющей дл  хвостовика 5 потенциального электрода 3, Детали Щупа соедин5потс  между собой фиг.вой гайкой 12.Ktroda 3, placed inside the current. The potential electrode 3 is made in the form of a rod with a cylindrical guide flange 4 and a shank 5 for current collection, the working part Eg 6 is flat with bevels and connected to the potential electrode 3 by means of a hinge 7 "To isolate the current electrode 1 from the potential 3 in the CURRENT ; electrode 1 is placed dielectric sleeve 8 (Fig. 1), simultaneously with guide and shoulder 4 of potential electrode 31 Springs 9 and Yu serve to create the necessary force of pressing electrodes to the metallized hole of the printed circuit board (Fig, 2), and the force at the time of contact The spring 9 is 8-10 times the force of the spring 10. Insulating washer 11 is an upf for the Yun spring of the guide for the shank 5 of the potential electrode 3, the Probe Parts are connected 5 points between each of the figs of your nut 12.

Контактное устройство работает следующим образом, При измерении сопротивлений- металлизированных отверстий щупы контактируютс  с двух сторон контролируемой платы. В момент касани  платы щупами рабочие концы 6 потенциальных электродов 3 контактируют с металлизированным отверстиемThe contact device operates as follows. When measuring the resistance of the metallized holes, the probes are in contact on both sides of the monitored board. At the moment of touching the board with the probes, the working ends of 6 potential electrodes 3 are in contact with the metallized hole.

обоими скосами, а шарнирное соединение 7 позвол ет зан ть его рабочей части оптимальное положение по отношению к металг изироаа1шому отверстию, при этом пружины 10 деформируютс . При дальнейшем сближении щупов конусные части 2 токовых электродов 1 самоустанавливаютс  в металлизировангных OTsepcTMspt, а пружины 9 деформируютс . Такое конструктивное решение обеспечивает равномерное контактирование обоих скосов рабочей части потенциального электрода с поверхностью контролируемого металлизированного от версти , что повышает точность измерени .both bevels, and the hinged connection 7 allows its working part to occupy an optimal position with respect to the metal hole, while the springs 10 are deformed. With a further approach of the probes, the conical parts 2 of the current electrodes 1 self-align in the metallized OTsepcTMspt, and the springs 9 deform. Such a constructive solution ensures uniform contacting of both bevels of the working part of the potential electrode with the surface of the controlled metallized branch, which improves the measurement accuracy.
