Abstract

Данное изобретение относится к устройству для электрического соединения дифференциального блока с автоматическим выключателем или подобным ему и дифференциальному блоку, снабженному таким устройством. Это соединительное устройство содержит некоторое количество проводников (6-9, 19), каждый из которых электрически соединен через один из своих концов с выходными зажимами дифференциального блока после прохождения через тороид (5) дифференциального блока, причем эти проводники предназначены для электрического соединения каждого из них своим противоположным концом с одним из выходных зажимов автоматического выключателя. Это устройство отличается тем, что, по меньшей мере, один из вышеупомянутых проводников (6-9, 19) является жестким проводником с твердой внутренней частью, причем этот проводник имеет первый конец (19a), предназначенный для электрического соединения с соответствующим зажимом автоматического выключателя, и второй конец (19b), приваренный в конце к контактной пластинке (26-29), механически или электрически соединенной с соответствующим выходным зажимом дифференциального блока (B).This invention relates to a device for electrically connecting a differential unit with a circuit breaker or the like and a differential unit equipped with such a device. This connecting device contains a number of conductors (6-9, 19), each of which is electrically connected through one of its ends with the output terminals of the differential unit after passing through the toroid (5) of the differential unit, and these conductors are designed to electrically connect each of them its opposite end with one of the output terminals of the circuit breaker. This device is characterized in that at least one of the above-mentioned conductors (6-9, 19) is a rigid conductor with a solid internal part, and this conductor has a first end (19a) for electrical connection with a corresponding terminal of a circuit breaker and the second end (19b), welded at the end to the contact plate (26-29), mechanically or electrically connected to the corresponding output terminal of the differential unit (B).
