Abstract
The utility model relates to a relay. The utility model aims to reduce that the old relay contact point has easy oxidization and the electrical abrasion phenomenon is generated. The utility model is composed of an airtight outer shell, a relay body, a lead-out pin and protective gas. The utility model is characterized in that the relay body is arranged in the airtight outer shell and is led out by the lead-out pin; a containing cavity in the airtight outer shell is filled with the protective gas. As the contact point is in the protective gas, when the relay acts, the protective gas with difficult ionization inhibits the further generation of electric arcs, and thus the electrical abrasion of the contact is reduced. Simultaneously, as the oxygen does not exist, the contact is not oxidized, and the service life of the relay is improved.
Description
The utility model is a kind of relay.
Existing relay, its contact is among the air, when the actuating of relay, owing to get an electric shock the indirectly existence of resistance of contact produces high temperature, makes the air ionization between the contact and produces electric arc, and contact thereby produce oxidation and electrical wear has reduced useful life.
The purpose of this utility model is to provide a kind of relay that can prevent contact oxidation and reduce its electrical wear.
Relay of the present utility model is made up of airtight shell, leading foot, relay main body, protective gas, and relay is arranged in the airtight shell, draws by leading foot, is filled with protective gas in the cavity volume in the airtight shell.
Advantage of the present utility model is: the gas between the contact is the protective gas of difficult ionization, thereby has reduced the generation of electric arc, and the contact electrical wear is reduced, and owing to do not have oxygen, so the contact oxidation phenomenon can not take place.
The utility model is described in further detail in conjunction with the accompanying drawings according to embodiment below.
1 is airtight shell among the figure, the 2nd, and relay main body, the 3rd, leading foot, the 4th, protective gas.
In an embodiment, protective gas has been selected gases such as carbon dioxide or argon gas, is the mixture of a kind of gas or several gases, and the relay main body is arranged in the airtight shell, is drawn by leading foot, the airtight envelope filled protective gas that has.When the actuating of relay; owing to existing contact resistance to produce high temperature between the contact; but protective gas such as carbon dioxide or argon gas is difficult ionized gas; thereby the gas in the contact gap can not form plasma and conducts electricity; thereby the further generation of controlling electric arc; reduced electric arc, the electrical wear of contact is reduced.In addition, owing to there is not oxygen, oxidation can not take place in the contact.The action of relay is drawn by leading foot, with the break-make of control circuit.
