Problems solved by technology
However, with the miniaturization of electrical equipment, the structure of the existing electromagnetic relay is complicated. For example, the swing of the movable iron piece needs to use a yoke and a hinge spring, which leads to the structure of the electromagnetic relay is not compact enough, and the assembly is inconvenient. It has been increasingly unable to meet the requirements of production design

The invention discloses an electromagnetic relay comprising a base, an electromagnet coil, an iron core, a movable iron piece, a linkage member, a static terminal and a moving terminal. The iron core is mounted on the base. The electromagnet coil is wound outside the iron core. The movable iron piece is movably mounted on the base. The upper end of the movable iron piece is connected with the linkage member. The other end of the linkage member is connected with the upper end of the moving terminal. The lower ends of the moving terminal and the static terminal are fixedly mounted on the base. The two edges of the lower end of the movable iron piece are each provided with an opening. A pressing part is formed between each opening and the end face of the lower end of the movable iron piece. A holding part extends from each of the two sides of the lower end of the iron core. The holding parts are accommodated in the openings and are pressed against the pressing parts respectively. The holding parts and the pressing parts are in contact to form an axis, and the movable iron piece swings around the axis. The electromagnetic relay of the invention has the advantages of compact structure and convenient assembly.
Description
technical field [0001] The invention relates to an electromagnetic relay, in particular to an electromagnetic relay with compact structure and convenient assembly. Background technique [0002] Electromagnetic relay is an automatic switch that uses smaller current and lower voltage to control larger current and higher voltage. It realizes this switching function by means of the electromagnet arranged inside, and by passing a small current to the coil of the electromagnet, the electromagnet generates a magnetic field, and the movable iron piece is attracted or released by using the generation or disappearance of the magnetic field. Furthermore, the movable iron piece drives the conductive shrapnel to attract or disconnect, so as to realize the conduction of the large current loop. However, with the miniaturization of electrical equipment, the structure of the existing electromagnetic relay is complicated. For example, the swing of the movable iron piece needs to use a yoke a...
