This invention has well physical properties, longer service time, high reliability, light weight, low cost, and wide application future.
Description
(1) technical field under
The present invention relates to a kind of device for switching, particularly a kind of have contact permanent-magnet near device for switching.
(2) background technology
Existing contact switch electrical equipment and disconnecting link switch are exposed in the air, the easy oxidation ablation in contact, the stolen goods dirt, not acid and alkali-resistance, easily electric leakage, easily cause electric shock accidents.The frequent open and close of rocker switch, mechanical part is easy to wear, and the life-span is shorter, and failure rate is higher, and disconnecting link switch mechanical connecting part is more easy to wear, and the life-span is shorter, easily causes electric shock accidents.
(3) summary of the invention
The present invention is in order to remedy the deficiencies in the prior art, provide a kind of significant prolongation switch useful life contact permanent-magnet is arranged near device for switching.
The present invention is achieved through the following technical solutions:
A kind of have contact permanent-magnet near device for switching, comprises contact point arm, is fixed on its surperficial armature and is fixed on its terminal moving contact, and its special character is: described contact point arm, armature and moving contact are positioned at a shell; But the outer position relative with armature of shell is provided with the permanent magnet of a level or vertical moving; The moving contact both sides are respectively equipped with normally opened contact, normally-closed contact in the shell, or are respectively equipped with some fixed contacts.
Of the present invention have contact permanent-magnet near device for switching, and the side that described contact point arm is relative with armature is provided with support and spring, and spring is between support and contact point arm.
The characteristic that the present invention utilizes permanent magnet and armature to attract each other just can be handled with very little operating physical force, and is flexible to operation.
Device for switching of the present invention can be made into and air insulated, also isolated simultaneously oxygen, because do not have the participation of oxygen, just there is not the problem of oxidation ablation in the contact, has prolonged the life-span of contact greatly, can install the contact arc quenching system additional, also can not adorn, this switch can be made into gas-filled type, vacuum type, hermetic type, various forms such as screen enclosed.The purpose of anti-oxidation, waterproof, protection against the tide, dustproof, explosion-proof, anticreep, protection against electric shock, anticorrosive property gas (liquid) body be can reach, in the useful life of significant prolongation switch, fail safe, reliability improved.
The present invention is simple in structure, and volume is little, and is in light weight, production and processing is convenient, and production cost is low, and it is few to consume copper material, the very strong market competitiveness is arranged, can be widely used in numerous areas such as family, rural area, city, factory, mine, navigation, Aeronautics and Astronautics, application prospect is very wide.
