Abstract

The invention belongs to the technical field of electric parameter measurement, and provides a shunting element for a printed circuit board. The shunting element is formed by bending a strip-type metal sheet, wherein at least one notch is formed in each of the opposite first and second ends of the strip-type metal sheet, so that the first end is divided into at least one first-type pin and at least one second-type pin, and the second end is divided into at least one third-type pin and at least one fourth-type pin; the width of the first-type pin is greater than that of the second-type pin, and the width of the third-type pin is greater than that of the fourth-type pin. The shunting element is integrally machined by using the strip-type metal sheets, and is simple in structure; the resistance of a finished product is not required to be regulated, so that manufacturing procedures are simplified; at the same time, a conventional terminal sheet part is rreduced, so that a resistance value can be increased or decreased according to actual needs, and the shunting element is high in flexibility; moreover, a welding procedure is not required, so that the shunting element has the advantage of small temperature drift.

Description

Technical field [0001] The invention belongs to the technical field of electrical parameter measurement, and particularly relates to a shunt element of a printed circuit board. Background technique [0002] The shunt component is a device that is widely used in communication systems, electronic complete machines, automatic control power supplies and other circuits to achieve current limiting and current sharing sampling detection. It generates voltage across the resistor when the DC current passes through the resistor. The principle is made. [0003] Figure 1a Shows a side view of a shunt element applied on a printed circuit board in the prior art, Figure 1b Yes Figure 1a The front view, taking the n-shaped structure as an example. The shunt element includes a resistor piece and an end piece for connecting to the printed circuit board. The resistor piece is shown in the unshaded part A, and the end piece is shown in the shaded part B. Among them, the resistance piece is made of ...
