Description
Technical field]
The utility model relates to a kind of power switch, particularly relates to a kind of high-power two-direction switch.
Background technology
The existing switch of falling the para-electric is various in style, but all have complex structure, can not the big electric current of break-make, support powerful defective.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, provides a kind of simple in structure, the big electric current of energy break-make, the powerful high-power two-direction switch of support.
For achieving the above object, the special feature of the high-power two-direction switch of the utility model is to comprise a U type support of being made up of base plate and side plate, and the transverse axis of a hinged upper end band lever is fixed with flap on the side plate of U type support on the transverse axis; The two ends of flap and base plate all are equipped with insulating base, all are fitted with the contact of two or three pairs of corresponding band binding posts about every end on the insulating base of correspondence; In two groups of contacts up and down, one group of contact is fixed on the insulating base, is shaped on the vertical insulation board of insulating contact on the insulating base, and another group contact cunning fits on the insulating base, and is fitted with support spring.So design, the sliding contact pressure that can increase behind the equipped support spring of contact between the contact of joining fully contacts contact, can guarantee the timely conducting of big electric current, can reduce the contact resistance between the contact again, can not make contact overheated.Vertical insulation board then can be used for stopping electric arc.During use, the binding post at flap insulating base two ends interconnects or the binding post at base plate insulating base two ends interconnects, and flap is connected power line and high-power electric appliance respectively with the binding post of any side of base plate.When the lever of transverse axis is upright, open circuit then, when lever is swung to a side then motor just change, when lever is swung to opposite side, then motor counter-rotating, thus realize the purpose of just changeing, reversing and disconnecting.It has simple in structure, can break-make big electric current, support powerful advantage.
As optimization, transverse axis middle part is below by the support column of the hinged lower end socket power assistant spring of pedestal, and the power assistant spring lower end is sleeved on the adjusting screw(rod) on the U type support base plate.Adjusting screw(rod) and U type support base plate are spirally connected, and just can regulate the tension force of power assistant spring by turning adjusting screw(rod) up or down.So design, the introducing of power assistant spring then can be played booster action to the spring side, and it is tightr that the contact of above and below is fastened, and contact is better, and it is also more laborsaving to remove when falling the lever.
As optimization, install a L type gag lever post that stretches out to a side side plate below the transverse axis; The gag lever post outer end is fitted with bumps pearl, is shaped on this side side plate and bumps the spacing hole that pearl is matched.So design, the introducing of L type gag lever post and spacing hole can prevent that then lever is not in place or offside, guarantees that contact normally contacts.
As optimization, this side side plate is shaped on the spacing hole of three curved distributions, middle interposition that the spacing hole correspondence is bumped pearl, and both sides spacing hole correspondence is bumped the side position of pearl.So design can guarantee accurate contraposition.
As optimization, the gag lever post front portion is shaped on centre bore, suit support spring and ball in the centre bore, and centre bore outer end diameter is less than ball diameter, and the ball front end protrudes from outside the centre bore front end hole wall.So design, have simple in structure, the convenient advantage of implementing.
As optimization, be fixed with above the flap and cover flap or and the insulating lid of binding post.So design, insulation effect is good.
As optimization, the sliding contact that fits on the insulating base is a cylindricality, and two ends stretch out insulating base, and an end is a contact, and the other end is the binding post of two wiring nut of wire connection.So design, the stroke of contact is big, more convenient equipped support spring.
As optimization, be shaped on the reducing hole of band boss on the insulating base of joining with the cylindrical contact cunning, the reducing post that sliding with it contact of joining also is the band boss is fitted with support spring between the boss of the boss in reducing hole and reducing post.So design, good with the form overall appearance of putting support spring, can protect spring better, more convenient equipped other parts.
As optimization, between the boss of support spring and reducing post, be fitted with heat insulating mattress.So design, the introducing of heat insulating mattress can prevent that then contact from directly conducting heat to spring, help preventing the spring deliquescing of being heated.
As optimization, be shaped on cylindrical hole on the insulating base of joining with the cylindrical contact cunning, sliding with it contact of joining also is cylindrical, is fitted with support spring between binding post one end and the insulating lid.So design then makes things convenient for the spring heat radiation.
After adopting technique scheme, the high-power two-direction switch of the utility model has simple in structure, can the big electric current of break-make, support high-power, the advantage of long service life.
