Abstract

The invention provides an electromagnetic relay and a movable contact spring of the electromagnetic relay. The electromagnetic relay comprises a contact assembly, an electromagnetic assembly, an armature assembly and a push card. The contact assembly is kept in a normally-open state or a normally-closed state through the magnetic attraction action of a permanent magnet in an armature. Conversion between the normally-open state and the normally-closed state of the contact assembly is triggered through a pulse electric signal, so that the electromagnetic assembly drives the armature assembly to drive the push card to move, and state conversion of the contact assembly is achieved through movement of the push card. The first end, located in the contact assembly, of the movable contact spring is fixedly connected to a leading-out piece, and a movable contact is fixed to the second end of the movable contact spring. The second end of the movable contact spring is connected with the push card. The movable contact spring comprises a plurality of overlapped reeds, and at least one reinforcing rib is formed at the second end of one of the reeds. Concave and convex ribs are additionally arranged at the head portions of all the reeds, the head portions of the reeds can be selectively hardened, and the mechanical strength of the reeds is improved.

Description

technical field [0001] The invention relates to a relay, in particular to an electromagnetic relay with higher operating reliability and its moving reed. Background technique [0002] The magnetic latching relay is a new type of relay developed in recent years, and it is an automatic switch. The traditional electromagnetic relay only plays the role of automatically turning on and off the circuit, while the normally open or normally closed state of the magnetic latching relay is completely dependent on the permanent magnet, and the switching state of the relay is triggered by a pulse electric signal with a certain width. Finish. When the contacts of the relay need to be in the open or closed state (that is, when the load is turned on or off), only the positive and negative DC pulse voltage is used to excite the coil, and the relay completes the switching between the open and closed states in an instant. Usually, when the contact is in the holding state, the coil does not ne...
