Description

Technical Field

[0001] The utility model relates to the technical field of abnormal sound prevention relays, in particular to an abnormal sound prevention type relay. Background Art

[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, it causes the controlled quantity to undergo a predetermined step change in the electrical output circuit. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] At present, traditional relays are generally composed of components such as electromagnets, contact groups, housings and other components. Among them, the contact group is generally composed of a moving contact and a static contact. When working, the moving contact moves toward the static contact under the action of the electromagnet, so that the moving contact and the static contact contact each other, achieving attraction. When the power is cut off, the electromagnet disappears, and the moving contact is reset under its own elasticity, so that the moving contact and the static contact are separated, achieving opening and closing.

[0004] Because, in order to ensure stable contact between the moving contact and the static contact, the traditional contact group is designed with an arc-shaped spring sheet on one side of the parallel sheet, such as Fig. 9 As shown, although the arc-shaped spring piece can make the moving contact and the static contact in stable contact, when the moving contact is separated from the static contact, the arc-shaped spring piece will easily come into contact with the external shell and produce a collision sound. When the staff judge whether the relay is damaged by the opening and closing sound, they are easily disturbed by the sound of the collision between the arc-shaped spring piece and the shell, resulting in the staff being unable to correctly judge whether the relay is working normally.
