Problems solved by technology

[0004] Although the shunt is such an inconspicuous small part, it is absolutely impossible to lack it, because it is a small part, and it is often installed more casually, but many accidents are caused by the desoldering of the shunt. Therefore, it is very necessary to design a shunt that is not easy to desolder

Abstract

The invention discloses a manganese-copper shunt difficult to desolder and application thereof. The manganese-copper shunt comprises a shunt main body (1), a mounting pin (2), a shunt base (11), a manganese-copper resistor (12), a shunt bottom plate (13), an assembling hole (21), a load binding post (111) and a measuring binding post (112). The manganese-copper shunt is concise and novel in structure, difficult to desolder, good in electromagnetic compatibility and easy to produce, and can be used for current limiting, current equalizing sampling detection and the like of loops such as a communication system, an electronic complete machine and an automatic control power supply.

Description

technical field [0001] The invention belongs to the field of shunts, and in particular relates to a manganese-copper shunt which is not easily desoldered and an application thereof. [0002] technical background [0003] The shunt is a short conductor, which can be made of various metals or alloys, and has connection terminals; its DC resistance is strictly adjusted; it is connected in series in the DC circuit, the DC current passes through the shunt, and the two ends of the shunt generate The millivolt DC voltage signal makes the pointer of the meter connected to both ends of the shunt swing, and the reading is the current value in the DC circuit. The so-called shunting means dividing a small current to push the meter indication. The smaller the ratio of the small current (mA) to the current in the large circuit (1A-tens of A), the better the linearity and accuracy of the ammeter reading. [0004] Although the shunt is such an inconspicuous small part, it is absolutely impo...
