Array-type adjustable cage-type PCB inductor

Abstract

The invention discloses an array-type adjustable cage-type PCB inductor. A PCB is provided with a plurality of cage-type annular coils which are arranged in a matrix manner, the cross section of the annular body of each cage-type annular coil is rectangular or trapezoidal, and turns of coils of each cage-type annular coil are welded on the PCB through triangular strip pads which have the same number as the turns of coils and correspond to the turns of coils in position; the position, on the PCB, of the central part of a polygon formed by the plurality of cage-type annular coils is provided with a center pad, and the center pad is connected with any triangular strip pad connected with each cage-type annular coil. According to the invention, gaps are left among turns of each cage-type annular coil, and are benefit for heat dissipation; by arranging the triangular strip pads, when the inductor is welded on the PCB, 1 / 3 length of each turn of inductor coil is welded on the PCB, and the coils are fixed well; multiple areas are welded on the PCB, the thermal transmission effect is better; when the inductance value is adjusted, the user only needs to take out different triangular strip pads and connect the triangular strip pads to the center pad, the inductance value adjustable scope is large, the relative inductance value is obtained accurately, and the array-type adjustable cage-type PCB inductor is simple to operate.

Description

technical field [0001] The invention relates to the field of inductance elements, in particular to an array-type adjustable cage-type PCB inductance. Background technique [0002] In the past circular inductor winding method, the required inductance is relatively large; or used in radio frequency circuit matching, the required error of the inductance is relatively accurate; when a large current requires a better heat dissipation environment. The traditional form of inductance cannot meet the needs of modern industrial production. [0003] There are problems with traditional inductors: [0004] 1. When the inductance is required to be large, the larger the inductance, the more turns of the coil, and the larger the volume of the inductance, which is not conducive to installation and placement. [0005] Since the parameters of the MOS tubes connected in front of the inductor cannot be exactly the same, and the traditional inductors can be adjusted with high precision, there ...

Problems solved by technology

It will become hot for a long time, which is not conducive to heat dissipation and affects circuit indicators

[0007] The layout of traditional synthetic inductors is four or more channels arranged side by side, and the position of the combined point cannot be evenly close to each channel, resulting in different lengths of output cables
