The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The present disclosure provides a connecting structure of a yoke and an iron core, a coil assembly, and a relay. The yoke and the iron core are provided, respectively, with a yoke assembly surface and an iron core assembly end corresponding to one another. One of the yoke assembly surface and the iron core assembly end is provided with a protrusion, and the other one is provided with a recessed hole, so that the yoke and the iron core are connected by means of a male/female-insertion interference fit between the protrusion and the recessed hole. End portions of the yoke and the iron core of the present disclosure are connected by means of a male/female-connection tight interference fit between a protrusion and a recessed hole matching one another, and the connecting position is located at an inner side position of the yoke assembly surface, so that the problem of magnetic leakage occurring at a riveting position due to existing yokes and iron cores being connected by means of riveting can be effectively alleviated, which can ensure that a magnetic field circulates inside of a magnetic circuit as much as possible.
