Relay

Abstract

The invention discloses a relay, and relates to the technical field of electronic components. The relay comprises a relay body, a protective cover is installed on the relay body, quick-wear parts on the relay body are arranged in the protective cover, a driving cavity is formed between the inner side and the outer side of the protective cover, and the top and the bottom of the driving cavity are fixed to the two ends of a positioning shaft respectively. According to the relay, the water inlet grooves are formed in the inner side and the outer side of the protection cover, so water drops on the surfaces of the inner side and the outer side of the protection cover can be guided, the water drops are discharged out of the protection cover through the drainage cavity, the water drops are prevented from dripping on quick-wear parts in the protection cover when a steamship shakes, and therefore, the service life of the relay can be greatly prolonged; in the shaking process of the steamship, the driving magnetic block in the protection cover is matched with the auxiliary drainage mechanism, so the drainage effect on water drops on the two sides of the protection cover can be further improved, and the service life of the relay can be further prolonged.

Problems solved by technology

[0004] In the relay used in the kitchen of a large ship, due to the high air humidity at sea, and the kitchen will also produce a large amount of water vapor during the cooking process, which further increases the air humidity. When the temperature drops, the water vapor in the air will It enters the inside of the protective cover through the heat dissipation gap between the protective cover and the relay, and then liquefies on the protective cover and drips onto the vulnerable parts inside the protective cover as the ship shakes, causing great damage to the vulnerable parts inside the protective cover. influence, which in turn leads to a reduction in the service life of the relay
