Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to an inductor structure capable of reducing pin oxidation. Background Art

[0002] At present, the main method of fixing the inductor is to install an epoxy base plate at the bottom of the inductor body, and the epoxy base plate has perforations for the pins of the inductor body to pass through at intervals on the edges of both sides. The existing perforations are through holes, so the pins need to be stripped before passing through the perforations, and then the epoxy base plate is installed and then glue is applied and baked. After the glue is baked, the pins are cut and soldered. Otherwise, the epoxy base plate is peeled after the board is installed. The epoxy base plate does not have space to accommodate a peeler. When the peeler peels the paint of the pins, the peeler is easy to collide with the epoxy base plate and scratch the epoxy base plate. However, since the pins are peeled in advance, the pins that have been peeled are exposed to the air for a long time, resulting in oxidation of the pins. Therefore, a longer soldering time is required during soldering, which increases the time cost. Utility Model Content
