Description

A kind of magnetic switch

Technical field

The utility model relates to a kind of line switching, is specifically related to a kind of magnetic switch.

Background technology

At present, the switch used on various circuits mostly is knife switch, and the knife switch structure is machinery folding, and after use a period of time, its sensitivity descends, and, because the mechanical component of plug-in strip folding is ceaselessly moved in moving process, its life-span is limited.In addition, the part-structure of knife switch is exposed in air, and especially, at the knife switch of outdoor application, when running into rainy weather, easily electric leakage, produce potential safety hazard; And irony part long term exposure perishable getting rusty in air of knife switch, thereby reduce knife switch useful life.

The utility model content

For knife switch limited problem in useful life in prior art, the utility model provides a kind of magnetic switch, and this magnetic switch is to use magnetic component as the folding member, and its sensitivity is not subject to the impact of opening/closing frequency, long service life.

The technical solution of the utility model realizes in the following manner: comprise switch enclosure, switch enclosure consists of lower chamber and the upper cover plate be arranged on upper cavity, be provided with fixed contact and movable contact in lower chamber, fixed contact is fixed on lower chamber inside, movable contact is hinged on lower chamber inside, movable contact is corresponding with fixed contact, be provided with the first magnet at movable contact away from an end of fixed contact, be provided with wire hole at fixed contact on corresponding lower chamber end face, upper cover plate is provided with chute, be provided with slide block with matching in chute, the slide block lower surface is fixed with the second magnet, centre line L 1 through movable contact is vertical with lower chamber bottom surface a2 with the plane a1 of the centre line L 2 of chute.

The end face that described wire hole is corresponding is provided with bolt hole, and described bolt hole place is provided with sealing ring.

The top edge of described lower chamber is provided with sealing gasket.

Described chute is U-shaped chute, at U-shaped chute openend, is provided with gag lever post.

Described the first magnet is permanent magnet.

Described the second magnet is permanent magnet.

Described lower chamber is the plastics lower chamber, and upper cover plate is the upper plastic cover plate.

Lower chamber is connected with upper cover plate by bolt.

With respect to prior art, on the utility model upper cover plate, the second magnet acts on mutually with the first magnet on the interior movable contact of lower chamber, control the first magnet in lower chamber by the second magnet on the slip upper cover plate, thereby make the movable contact on the first magnet realize opening and closing movement.The utility model is not to realize opening and closing movement with mechanical component, by the first magnet and two magnetic components of the second magnet, realizes folding, even long-time, uses, and its sensitivity can not be affected yet, and has extended useful life.The setting of lower chamber sealing gasket and sealing ring simultaneously, make the integral body that whole switch enclosure is a sealing, can prevent that each electric elements of switch are exposed, effectively waterproof, anticorrosion, thereby improved fail safe, the durability of switch, greatly extended the useful life of switch; The utility model is also by the setting of bolt hole, and by wire hole, wire out is tightly fixing, can effectively prevent the loosening of wire, and can prevent that the wire in switch enclosure is tightened up or pulls open.

The accompanying drawing explanation

The structural representation that Fig. 1 is the utility model opening;

The structural representation that Fig. 2 is the utility model closed condition;

The vertical view of lower chamber when Fig. 3 is the utility model connection wire;

The structural representation that Fig. 4 is the utility model slide block;

Fig. 5 is the structural representation that the utility model a1 face is vertical with the a2 face.

Wherein, the a1 face is the plane of the second magnet through centre line L 1 with the centre line L 2 of chute of moving contact; The a2 face is the lower chamber bottom surface.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, a kind of magnetic switch, comprise switch enclosure, switch enclosure consists of lower chamber 1 and the upper cover plate 2 be arranged on upper cavity, be provided with fixed contact 3 and movable contact 4 in lower chamber 1, fixed contact is fixed on lower chamber inside, movable contact 4 is hinged on lower chamber 1 inside, movable contact is corresponding with fixed contact, be provided with the first magnet 5 at movable contact 4 away from an end of fixed contact 3, be provided with wire hole 7 at fixed contact on corresponding lower chamber end face, upper cover plate 2 is provided with chute 8, be provided with slide block 9 with matching in chute 8, slide block 9 lower surfaces are fixed with the second magnet 10, centre line L 1 through movable contact is vertical with lower chamber bottom surface a2 with the plane a1 of the centre line L 2 of chute.

Further restriction, the end face of wire hole 7 correspondences is provided with bolt hole 12, and described bolt hole 12 places are provided with sealing ring, and the top edge of lower chamber 1 is provided with sealing gasket 6, makes the integral body that whole switch enclosure is a sealing, and effectively waterproof, strengthen the fail safe of switch.

The utility model chute 8 is U-shaped chute, at U-shaped chute openend, is provided with gag lever post 11, and anti-limited slip block 9 breaks away from chute 8 in the process of sliding, and when not using switch for a long time, gag lever post 11 can be taken off, then slide block 9 be taken off and deposits, in order to using next time; In addition, when the service worker servicing machine needs open circuit, slide block 9 can be taken off, oneself is carried, and to prevent that others is switch opens, has guaranteed maintenance personal's inherently safe.
