Problems solved by technology

[0003] There are two main ways to fix the magnetic steel in the single-coil magnetic latching relay in the prior art. One is to use the magnetic steel to be clamped and fixed. Stability, and the dimensional accuracy of parts is difficult to control, difficult to process and other issues
The other is to adopt the fixing method of magnetic steel dispensing. This kind of magnetic steel dispensing fixing method directly puts glue on the magnetic steel, which will make the dispensing operation not easy, and it is easy to make the glue contaminate the relay itself and Disadvantages such as operating platform

Abstract

The invention discloses a single-coil magnetic latching relay which comprises a magnetic circuit part. The magnetic circuit part comprises a coil rack, a steel magnet, an iron core and a yoke iron. The iron core is inserted into a center hole of the coil rack. One coil rack end corresponding to the center hole is provided with a groove. One side of the yoke iron abuts and is fixed on the coil rack end provided with the groove. The steel magnet is accommodated in the groove and placed between the iron core and the yoke iron. One side of the yoke iron is provided with a first through hole for glue dispensing. The end face on one end of the coil rack is provided with a glue guide tank. One end of the glue guide tank is communicated with the first through hole while the other end leads to the groove. By arranging the glue dispensing hole and the glue guide tank, the relay makes the steel magnet firmly fixed and thus prevents problems caused by loosening of the steel magnet. Easy glue dispensing operations and accurate glue dispensing positions are achieved. Meanwhile, the relay itself and an operating platform will not be easily polluted during a glue dispensing process.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to a single-coil magnetic latching relay. Background technique [0002] The magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. The magnetic latching relay, like other electromagnetic relays, can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the effect of the permanent magnet, and the switching state of the relay is triggered by a pulse electric signal of a certain width. [0003] There are two main ways to fix the magnetic steel in the single-coil magnetic latching relay in the prior art. One is to use the magnetic steel to be clamped and fixed. Stability, and the dimensional accuracy of parts is difficult to control and difficult to process. The other is to adopt the fixing method of magnetic steel dispens...
