Abstract

The invention discloses an anti-magnetic field protective manganese-copper shunt, comprising: a shunt body, a lead interface and an anti-magnetic shell, the outside of the shunt body is wrapped with an anti-magnetic shell, and one side of the shunt body is connected A lead interface is provided, and the lead interface passes through the anti-magnetic shell; the lead interface includes an insulating shell, a connecting block, a connecting channel, a sealing ring and a tightening nut; a protective manganin shunt that is anti-magnetic field is also disclosed Working method: On the one hand, it resists the influence of the magnetic field on the shunt and improves the accuracy of the shunt; on the other hand, it enhances the firmness of the connection between the shunt and the lead wires, reduces the occurrence of loosening and other phenomena, and improves the degree of sealing at the same time.

Description

technical field [0001] The invention belongs to the field of new material manufacture, and in particular relates to an anti-magnetic field protective manganin shunt and a working method thereof. Background technique [0002] Manganin shunt is a kind of current measuring element, which has the characteristics of high precision and low temperature coefficient, and can well adapt to the high-precision production of modern industry. It is an electronic component widely used at home and abroad. It has a wide range of applications and development Great potential. [0003] However, as a new type of material and specialized product, it is often used in various extreme environments, which also increases the quality test of manganin shunts. Most of the current manganin shunts are only suitable for The scope of application of the original shunt is still not strong against extreme environments, and the product quality is poor. At the same time, the current shunts all use the old-fashio...
