Embodiment Construction

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0034] In the relay of the related art, since there is no overload protection device, when the relay is turned on, once the load current is too large or the circuit is short-circuited, it is easy to cause sintering, which will cause the product to lose its function and cause danger. In addition, there is no arc extinguishing device in the above technology, so the arcing time is long and the service life of the product is short. In order to solve one of the technical problems in the related art at least to a certain extent, the pr...

Abstract

The invention discloses a relay. The relay comprises an enclosure, a bottom plate and a driving device, wherein at least one static contact group is arranged on an enclosure, the static contact group comprises two static contacts, the two static contacts are isolated with each other, a baffle wall is arranged in the enclosure and is spaced between the two static contacts of the static contact group, at least one movable contact group corresponding to the static contact group is arranged on the bottom plate, the movable contact group comprises two movable contacts, a fuse is arranged on the bottom plate, the two movable contacts of the movable contact group are electrically conducted by the fuse, the bottom plate is movably arranged in the enclosure between a connection position where the movable contact group and the static contact group are in contact and a disconnection position where the movable contact group and the static contact group are separated, and the driving device is connected with the bottom plate so as to drive the bottom plate to move between the connection position and the disconnection position. According to the relay disclosed by the embodiment of the invention, the baffle wall is arranged, thus, an arc can be rapidly extinguished by the baffle wall during the connection and disconnection process of a plurality of static contacts, and the safety and the stability of the relay are improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a relay. Background technique [0002] During the use of electrical appliances, there may be short-circuit problems, and during the use of relays, short-circuit may cause problems such as excessive load current or circuit sintering, which will cause the product to lose its function and cause malfunctions in use. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a relay that reduces or avoids potential safety hazards that may be caused by excessive load current or short circuit. [0004] The relay according to the embodiment of the present invention includes: a casing, on which a static contact group is provided, and the static contact group includes two mutually insulated static contacts, and a retaining wa...
