The structure is characterized in that the rectifier diodes are extruded with the pole plate via vertical stripes; the output screws are pressed on the pole plate through pressure bars and clamps of pressure equipment; a head pattern structure of each output screw comprises convex portions and concave portions; the convex portions of the head pattern structure of each output screw are recessed in the pole plate and the concave portions of the head pattern structure of each output screw are fitted with the pole plate; the pole plate and the head pattern structures of the output screws are distributed in a high-low staggered manner; and a root groove of each screw is filled by deformation of the pole plate. The advantages are that the structure has a self-locking function; the structure prevents rotation and disengagement; the contact area is increased; the contact resistance is reduced; and the loss is reduced.
Description
Technical field
The present invention relates to a kind of automobile generator rectifier electric current output screw structure, belong to automobile generator rectifier field, specifically a kind of automobile current generator self-locking screw-rod structure.
Background technology
The effect of automobile current generator charges a battery and powers to power consumption equipment on car.The effect of auto rectifier after rectifier diodes rectification, changes the three-phase alternating current that AC generator for vehicle stator coil produces into direct current, charge to automobile storage battery and power to other electrical appliance of automobile, help car eliminates the ability that sparks, the output of increase torsion, the reaction of quickening throttle, prolongation battery, shortening auto activation engine time, raising ignition effectiveness etc. of noise jamming, raising power-supply system.Wherein electric current is outwards exported by the output screw of rectifier, and the reliability of output screw directly affects the output of electric current, and then affects the reliability of generator.
Current automotive rectifier output screw, mostly be straight burr extrusion structure or Special-shaped head anti-rotation structure, its anti-rotation is effective, Anti-extrusion ability, and conductive contact surfaces is little, and resistance is comparatively large, and loss is larger.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of automobile current generator self-locking screw-rod structure, after press-fiting, it has anti-rotation and anti-fall function concurrently, and enlarge active surface, reduce contact resistance, reduce loss.
To achieve these goals, the technical solution used in the present invention is: a kind of automobile current generator self-locking screw-rod structure, comprises pole plate, output screw and rectifier diode; It is characterized in that: rectifier diode is pressed together by straight burr and pole plate, output screw is squeezed on pole plate by the press rods of press device and fixture, the head flower shape structure of described output screw is male-type and umbilicate type, the male-type of output screw head flower shape structure is recessed in pole plate, umbilicate type and the pole plate of output screw head flower shape coincide, pole plate and output screw head flower shape structure are for being just interspersed, and the deformation that described pole plate produces is filled in the groove of screw root.Described output screw is steel screw rod, and its profile and head flower shape structure are by cold-heading molding, and described screw root groove is formed by Vehicle Processing.
Described pole plate is by aluminium plate punch forming, forms pole plate through hole during punching press; Pole plate through hole by with screw extruding after, formed assembling after pole plate hole shape.
Through hole reserved by the pole plate of described generation deformation, forms small―gap suture and coordinate after pole plate through hole and output screw extrude.
Described output screw head has colored shape structure, makes pole plate can produce deformation under less pressure.
Described pole plate plays support and electric action, and rectifier diode is direct current AC conversion, and electric current exports by output screw.
The invention has the beneficial effects as follows: owing to adopting pole plate and output screw head flower shape structure height to be interspersed, make output screw have anti-rotation function; Because the deformation adopting pole plate to produce is filled in the root groove of output screw, output screw is made to have anti-fall function; Adopting the anti-rotation of output screw and putting deviates to make screw rod to form self-locking.Solve the Anti-extrusion problem of output screw straight burr extruding screw and Special-shaped head screw rod; Enlarge active surface, reduces contact resistance, reduces loss simultaneously.
