Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to a coil embedded inductor. Background Art

[0002] As a precision electronic instrument, the inductor has very high requirements for its production and installation. In the existing inductors, when the end of the enameled wire is pressed against the frame, the end of the enameled wire protrudes outside the isolation cover. Since the enameled wire itself has a certain thickness, the accuracy cannot be guaranteed when it is bent and pressed against. It is very easy to cause the pressed part to be uneven during the reverse pressure, resulting in non-standard height dimensions of the finished inductor, making the subsequent installation of the whole machine inconvenient and easily causing installation size errors.

[0003] After searching, Chinese Patent Publication (Announcement) No. 202220387686.4 discloses an embedded inductor. This patent removes the paint film of the coil by laser stripping or grinding, which has the effect of unifying the size of the finished product, but the pin distance of the inductor cannot be adjusted. Due to the wide range of use scenarios of inductors, when some emergency equipment is temporarily damaged and an inductor is urgently needed, if the pins of the inductor are fixed, it will lead to the inability to match circuit boards of different sizes, so that the pins of the inductor need to be adjustable, and the current inductor core has insufficient corrosion resistance and shielding properties. Therefore, it is necessary to design an inductor with an embedded coil. Utility Model Content
