Abstract
The invention provides a bus transformer and electronic equipment. The bus transformer comprises a shell with a containing groove, and an upper cover arranged on the opening of the containing groove in a covering mode, wherein the upper cover is hermetically connected with the shell so as to make the containing groove form a sealed space, the bus transformer further comprises a first magnetic ringarranged in the containing groove, a first winding wound on the first magnetic ring, a second magnetic ring arranged in the containing groove and spaced from the first magnetic ring, a second windingwound on the second magnetic ring, a plurality of pins fixedly arranged on the shell and a pouring sealant filled in the containing groove, the first winding and the second winding are electrically connected with the corresponding pins respectively, and the pouring sealant is used for packaging the first magnetic ring, the first winding, the second magnetic ring and the second winding in the containing groove. Compared with the prior art, the bus transformer disclosed by the invention has high sealing strength and strong salt spray resistance, and elements in the containing groove are not easy to erode.
Description
technical field [0001] The invention belongs to the technical field of small transformers, and more specifically relates to a bus transformer and electronic equipment. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). At present, as electronic equipment tends to be more and more miniaturized, high-density surface-mounted small transformers have become a direction for the miniaturization of electronic equipment, and chip transformers are increasingly used in various electronic equipment. However, the sealing ability of the existing SMD transformer is poor, which reduces the anti-salt spray ability of the SMD transformer. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a bus transformer and electronic equipment, so as to solve the technical problems of low s...
