Shielding layer manufactured by copper-clad plate

Abstract

The invention discloses a shielding layer manufactured by a copper-clad plate. The shielding layer comprises an insulating layer and copper coatings, wherein the copper coatings include a first coppercoating and a second copper coating; the first copper coating is arranged on one side of the insulating layer, and the second copper coating is arranged on the other side of the insulating layer; thesecond copper coating is positioned at one end on the other side of the insulating layer; a plurality of soldering round holes used for soldering fixation are formed in the other end of the second copper coating on the insulating layer; an insulating position is arranged between the first copper coating and the edge of the insulating layer. The shielding layer disclosed by the invention has the beneficial effects that the copper coatings are arranged on the insulating layer, so that the insulating layer is flexible in design and can be simply processed and formed, and plated with copper on the surfaces to serve as the shielding layer; meanwhile, the two sides can be freely plated with copper, so that the two sides are not connected with each other, and after the shielding layer is rounded, the insulating layer is capable of effectively partitioning circuits at two ends; the shielding layer does not form a loop at the joint, the joint structure is simple, and the soldering round holescan be fixedly soldered by virtue of soldering, so that the joint process is simple.

Description

technical field [0001] The invention relates to the field of electrical coupling and isolation between high and low voltage packets of transformers, in particular to a shielding layer made of copper clad laminates. Background technique [0002] The electrical coupling isolation between the high and low voltage packages of the transformer is realized by the shielding layer. The existing shielding method is to use a whole piece of copper sheet or wrap the low voltage package with a winding wire, and the shielding layer cannot form a closed loop to isolate the electrical coupling. . The shielding effect of the copper plate shielding layer is good, but it is easy to form a closed loop and cause a short circuit fault; there must be enough insulating layer between the coils in the winding method to ensure that no closed loop is formed, so the shielding effect is poor, and the number of turns of the coil is large. High pressure will be generated at the head and tail ends, posing s...
