Abstract
The invention relates to a conductive contact, in particular to a zigzag secondary camber conductive contact used for switches, relays and contactors, comprising a group of two contacts: a movable contact and a fixed contact; the movable contact and the fixed contact are respectively a concave camber and a convex camber which are coincident to each other; the invention uses the curve contact to replace a planar contact or point contact, solves the problems that the contact area of the conductive contact is extremely finite and the contact state is unstable, and overcomes the shortages that the existing conductive contact technique and product have weak current passing capability and the contacts are easy to be burned.
Description
Technical field
The present invention relates to a kind of conductive contact, particularly relate to the quadratic surface conductive contact that a kind of concave, convex that is used on switch, relay and the contactor coincide.
Background technology
Traditional conductive contact, regardless of material, its shape all is that two spheres are relative, or two planes are relative, a sphere is also arranged to a plane.No matter be that sphere is relative, the plane is relative, or sphere is relative with the plane, and its contact area is all very limited.Limited contact area has caused the contact resistance increase, has hindered passing through of big electric current, and the heat of generation increases and accumulates.By the ability of electric current, be the most important index of conductive contact, and the contact of small size is the fatal place that influences this index.The form of this traditional contact point, from system analysis engineering, the angle of control theory sees that protruding in protruding, promptly two spheres are relative, play pendulum forever.The contact causes little displacement when slight vibrations or thermal expansion distortion, might produce spark, and the time has been grown the contact of can ablating gradually.
Summary of the invention
The purpose of this invention is to provide a kind of conductive contact, the quadratic surface conductive contact that just provides a kind of concave, convex that is used on switch, relay and the contactor to coincide.The invention solves that the conductive contact contact area is very limited, the contact condition problem of unstable, remedied existing conductive contact technology and the ability of product by electric current a little less than, the ablate deficiency of contact easily.
A kind of conductive contact of the present invention comprises one group of dynamic and static two contact, and dynamic and static contact is respectively the concave, convex curved surface that matches, and the present invention adopts curved surface to contact to replace plane contact or some contact.
As optimized technical scheme:
Aforesaid a kind of conductive contact, wherein, described curved surface is a quadratic surface, quadratic surface is meant all figures of ternary quadratic algebra equation correspondence under three-dimensional coordinate (x, y, z).
Aforesaid a kind of conductive contact, wherein, described quadratic surface is sphere, ellipsoid, hyperboloid, parabola, straight cylindrical surfaces or straight taper seat.
A kind of conductive contact of the present invention, comprise two quadratic surface contacts that match, quadratic surface is the general designation of all figures of ternary quadratic algebra equation correspondence under three-dimensional coordinate (x, y, z), modal quadratic surface is sphere and straight cylindrical surfaces and straight taper seat, in addition, quadratic surface also comprises ellipsoid, hyperboloid (be divided into not only the hyperboloid of one sheet and hyperboloid of two sheets) and parabolic (but also be divided into paraboloid and hyperbolic-parabolic, the latter claims the saddle face again).One of them contact, dynamic and static contact of one group of conductive contact is the curved surface that protrudes, and can be sphere, ellipsoid, the hyperboloid of one sheet, the paraboloid of revolution or hyperbolic-parabolic; Another contact is sunk curved surface, and corresponding is sphere, ellipsoid, the hyperboloid of one sheet, the paraboloid of revolution or hyperbolic-parabolic.When the contact of two contacts, the curved surface of protrusion and sunk curved surface should be curved surfaces and the overlapping of curved surface.From system analysis engineering, the angle of control theory is seen, this combination, when system is disturbed, no matter be slight vibrations or thermal expansion distortion, system always more and more tends towards stability, promptly two contacts can be leaned on more and more closelyr, only can change to the increasing trend of contact area.Compare it with traditional contact and can become line (curve) contact or face (curved surface) contact by contacting.In identical space, it is big that the contact area of the contact gear ratio plane contact of curved surface is wanted.The sphere area and the area of a circle that equate with radius r compare sphere area computing formula: 4 π r
2, area of a circle computing formula: π r
2Identical diameter, the hemisphere area is bigger one times than the area of a circle.Like this, compare with traditional contact point, use identical materials, the identical materials consumption has just changed version, has promptly increased contact area, has increased exponentially the electric current handling capacity.Save non-ferrous metal undoubtedly, saved the energy and the resource of producing these non-ferrous metals.
The invention has the beneficial effects as follows:
A kind of conductive contact of the present invention has adopted reliable curved surface contact, makes the maximization of conductive contact contact area, and contact condition is stable; Compare with traditional conductive contact, with same metal material, strong by the ability of electric current, the contact is not easy ablated.
