Shunting element for printed circuit board

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 electric parameter measurement, in particular to a shunt element of a printed circuit board. Background technique [0002] The current shunt element is a device widely used in communication systems, electronic complete machines, automatic control power supplies and other circuits to realize current limiting, current equalization sampling and detection. principle 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 of the n-shaped structure is taken as an example. The shunt element includes a resistance piece and a terminal piece for connecting to a printed circuit board. The resistance piece is shown as part A without shading, and the terminal piece is shown as part B with shading. Among them, the resistance piece is made of manganese copper, and in order to reduce contact resistance and temperature ...
