Description

Closed magnetic force mains switch

Technical field: the utility model relates to a kind of power control, relates in particular to a kind of mains switch that utilizes magnetic force control switching electricity.

Background technology: at present, no matter be that traditional lighting switch or power supply plug-in strip adopts Open architecture mostly, because most of electric elements are directly exposed in the air, the surface of element is easily because of oxidation causes loose contact, and also causes electric shock accidents in a humid environment easily; In addition, traditional lighting switch or power supply plug-in strip in use are easy to generate arc light, and the various casualty accidents that cause therefrom happen occasionally, and are very dangerous.

Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of long service life, has the closed magnetic force mains switch of protection against the tide, explosion prevention function.

The technical solution of the utility model comprises box body, magnet, iron core, electrode slice and lid, and the box body internal fixation has static magnet, rest pad and two cube electrode sheets, and each fixes an outwardly directed binding post on two cube electrode sheets; The conduction lever that one end is fixed with iron core is movably arranged on the rest pad, and lid is airtight to be fixed on the box body, and moving magnet is placed on the surface with the corresponding lid in iron core position.

Compared with the prior art, the utility model is owing to adopted the box body of sealing, and most of electric elements and air are isolated, has therefore overcome effectively because the defectives such as loose contact that element causes because of oxidation, prolonged useful life, also can not cause electric shock accidents simultaneously because of making moist; In addition, because contact point of power source is sealed in box body inside, can not produce arc light or spark in the use; Because contact point and air are isolated, even if generation arc light or spark can not cause injury accidents such as blast or fire yet.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that A among Fig. 1 is to view;

Fig. 3 is the B-B cutaway view among Fig. 1.

Among the figure: pin 1 moving magnet 2 lids 3 iron cores 4 box bodys 5 static magnets 6 rest pads 7 conduction levers 8 electrode slices 9 binding posts 10

Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

In Fig. 1～3, static magnet 6, rest pad 7 and two cube electrode sheets 9 are fixed in the box body 5, and rest pad 7 is fixed with the binding post 10 that stretches out outside the box body 5 on each electrode slice 9 between static magnet 6 and electrode slice 9; The conduction lever 8 of Z font is installed on the rest pad 7 by pin 1, and conduction lever 8 can swing up and down around pin 1; Be fixed with iron core 4 at conduction lever 8 corresponding to an end of static magnet 6; Lid 3 is fixed on the box body 5 and with its sealing, places the moving magnet 2 of a magnetic force greater than static magnet 6 on the surface of lid 3 corresponding to the position of iron core 4.In order to reduce machining accuracy and to improve stability in contact, also the power contact that high conductivity metal is made can be set at the contact position of electrode slice 9 and conduction lever 8.

Claims

1. closed magnetic force mains switch, comprise box body, magnet, iron core, electrode slice and lid, it is characterized in that: box body (5) internal fixation has static magnet (6), rest pad (7) and two cube electrode sheets (9), goes up each at two cube electrode sheets (9) and fixes an outwardly directed binding post (10); The conduction lever (8) that one end is fixed with iron core (4) is movably arranged on the rest pad (7), and lid (3) is airtight to be fixed on the box body (5), and moving magnet (2) is placed on the surface with the corresponding lid in iron core (4) position (3).
