Modular coil plate and coiling assembly thereof, and plane transformer comprising coil plate or coil assembly

Abstract

The invention provides a modular coil plate. The modular coil plate comprises a plane coil body, and connecting pins which extend from two ends of the coil body, wherein the connecting pins are respectively positioned at the first position in the periphery of an imagination geometric figure of the coil body, and the second position which is in the periphery of the geometric figure and far away from the first position. The invention further discloses a structure combining a plurality of modular coil plates, and a plane transformer using the modular coil plate. The coil plate and the plane transformer using the coil plate are simple and convenient to manufacture and suitably applied to surface adhering and mounting.

Description

technical field [0001] The invention relates to a modularized coil plate, in particular to a coil plate applied to a planar transformer and a planar coil containing the coil plate. The invention provides a technique for assembling a multi-layer planar coil with a modular coil plate. The coil plate has a modular design, which is convenient for serial connection with other coil plates. The invention also discloses a planar transformer using the coil board or its coil board assembly. Background technique [0002] Transformers are critical components in powering electronics. Existing transformers are bulky and cannot meet the requirements of product miniaturization. Planar transformer (Planar transformer, or planar transformer) is a transformer formed by laying copper foil and other conductive foils as windings on a multilayer printed circuit board (PCB), which can greatly reduce the thickness of the transformer. Planar transformers are widely used in communication, computer...

AI Technical Summary

Problems solved by technology

[0011] From the technical status of planar transformers, it can be seen that the industry has spared no effort in the development of the miniaturization of planar transformers, but it is difficult to get rid of the conventional design of planar transformers made of printed circuit boards in the existing technology

The proposed designs all use a single-layer winding board as a combined unit, and it is impossible to propose a design that truly achieves the purpose of multi-turn winding

In addition, although there is a specific known technology that proposes the design of connecting multiple winding boards in series, the connection method is fixed, and only a specific winding board structure can be provided for the application of winding board modules with a specific number of layers or turns. It does not have a modular design, and cannot be combined or extended according to the needs of use
