Abstract

The invention discloses an electromagnetic relay capable of effectively reducing contact bounce. The electromagnetic relay comprises a static spring and a base, wherein the static spring comprises a static reed arranged on the base and a static contact. The static reed is provided with a static contact mounting part, and the static contact is fixed on one surface of the static contact mounting part of the static reed. In the static contact point mounting part of the static reed, a first inclined part is arranged on the back face corresponding to the static contact. In the based, a second inclined part is arranged at a position corresponding to the first inclined part. When the static reed is arranged on the base, the first inclined part of the static reed is in contact with the second inclined part of the base. According to the electromagnetic relay, the reliability of the contact between the static spring and the bottom seat / base can be ensured, so that the contact bounce is effectively reduced. The generation of the scraps in the assembling process can also be reduced.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to an electromagnetic relay capable of effectively reducing contact bouncing. Background technique [0002] The relay is an electronic control device, which has a control system (also known as the input circuit) and a controlled system (also known as the output circuit), usually used in automatic control circuits, it actually uses a smaller current to control a larger An "automatic switch" of electric current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] The electromagnetic relay usually includes components such as a moving spring, a static spring and a base (or base). The moving spring and the static spring cooperate to realize the contact and separation of the contacts, and the static spring is usually fixed on the base. The existing electromagnetic relay will bounce back at the moment when the dynamic an...
