Plug-in common mode inductor
This utility model discloses a through-hole common-mode inductor, comprising a main body, which includes a protective shell, a base plate, and a top plate. A base is provided inside the protective shell, and the common-mode inductor main body is mounted on the base. The common-mode inductor main body has four sets of through-hole pins penetrating the base plate. A protective component includes a fixed insulating sleeve located outside each set of through-hole pins, and a telescopic insulating sleeve slidably connected inside each fixed insulating sleeve for protecting the through-hole pins. An installation assembly includes fixed seats located on both side walls of the protective shell, each fixed seat containing a locking block. The base has a locking groove for connecting with the locking block, used for assembling and disassembling the common-mode inductor main body. The protective component of this utility model protects the through-hole pins, preventing damage when the through-hole common-mode inductor is not in use. The installation assembly enables quick assembly and disassembly of the protective shell and the through-hole common-mode inductor, facilitating rapid installation and use of the through-hole common-mode inductor.
