Description
Technical field
The present invention relates to a kind of switches, more particularly, to a kind of electricity disconnected double and big for the list of electric tool and similar appliances
Stream switch.
Background technique
The switch being traditionally used on electric tool and similar appliances is all one group of contact disjunction, one circuit (double break list
And single disconnected list and switch), breaking current ability is relatively small.Currently, with the fast development of motor and battery technology,
The power of electric tool and similar appliances is increasing, it is required that the breaking current ability of switch is also increasing, single and structure
Breaking current be inadequate.
In addition, electric tool is when in use, power is larger, therefore can generate biggish electric current, this is separating contact
Moment can generate electric arc, but traditional switch to this part also without corresponding safeguard measure.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of high-current switch, has two groups of contacts, while disjunction one
Route, therefore breaking current increases one times.
The technical solution adopted by the present invention to solve the technical problems is: a kind of high-current switch, including pedestal, upper cover and
Handle, the upper cover cover on the pedestal, are provided with fixed touching plate and gangway support in the pedestal, further include a magnet, institute
One end setting of gangway support is stated there are two card slot, is provided with a springboard, the bottom of each springboard in each card slot
It is provided with movable contact, there are two fixed contacts for setting on each fixed touching plate, and the handle is after the upper cover described in insertion
In pedestal, the setting of the bottom of the handle is provided with the first spring and sliding block in the blind hole, the sliding block exists there are two blind hole
The springboard is held out against under the action of first spring, the magnet, which is arranged on the pedestal, is located at fixed touching plate one end position
Set place.Our switch tool there are two movable contact and two stationary contacts, therefore the electric current being able to bear compared to it is original only
There is the switch of one group of movable contact and stationary contact to be doubled.In addition magnet is provided at stationary contact of the present invention, what magnet generated
Magnetic field can dispel the raw electric arc of movable contact and stationary contact separation production, substantially prolong the service life of contact.This switch utilizes
By two groups of contacts, one circuit of disjunction is referred to as double and structure simultaneously, and the lead-out wire of switch becomes a route, another electricity again
It is short out to connect, it is referred to as single disconnected, so being known as single disconnected double and structure.
In above-mentioned technical proposal, it is preferred that further include second spring, the handle is arranged in described second spring one end
The other end of bottom, the second spring is arranged on the pedestal.The effect of second spring be allow handle under normal circumstances
In the most position of upper cover, that is, normal state lower switch is stretched out in the position disconnected, only pushing handle can just be connect
It is logical.
In above-mentioned technical proposal, it is preferred that the upper cover has two opposite side walls, and it is logical that first is provided on the side wall
Hole is provided with protrusion on the lateral wall of the pedestal, and the protrusion is caught in the first through hole.First through hole is matched with protrusion
Conjunction makes the connection of upper cover and pedestal relatively reliable.
In above-mentioned technical proposal, it is preferred that the region that the handle passes through the upper cover is provided with second through-hole, institute
The border for stating the second through-hole is provided with a circle ring block, is cased with sealing cover on the ring block.The effect of sealing cover is to prevent ash
Dirt enters in pedestal.
In above-mentioned technical proposal, it is preferred that the magnet is located at the middle position of two fixed contacts.This position energy
Enough take into account the arc extinguishing of two groups of contacts.
In above-mentioned technical proposal, it is preferred that there is the wraping plate bent towards sliding block at the top of the springboard.Handle is past
In upper motion process, sliding block is contacted under the action of the first spring with wraping plate, and the other end of springboard is fixed with the one of movable contact spring
End end is tilted, and this structure can substantially increase contact disjunction power, and bonding, which occurs, even if contact to disengage.
In above-mentioned technical proposal, it is preferred that the bottom of second sliding block is arranged in the third solenoid valve.
The beneficial effects of the present invention are: there are two movable contact and two stationary contacts for our switch tool, therefore even if having
It wherein breaks down for one group, another set can also substitute work, therefore substantially increase stability of the invention.In addition this hair
Magnet is provided at bright stationary contact, the magnetic field that magnet generates can dispel the raw electric arc of movable contact and stationary contact separation production,
Substantially prolong the service life of contact.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is stereoscopic schematic diagram of the invention.
Fig. 2 is schematic cross-sectional view of the invention.
Fig. 3 is the schematic diagram that the present invention removes after upper cover and pedestal pair.
