Abstract
Alternator rectifying bridge for vehicle fin, its special character is: described rectifier bridge heat sink body is V-arrangement and left, right symmetry, left arm and the right arm of rectifier bridge heat sink body are respectively equipped with a left side, three diode press-in hole of right symmetry, at the left arm of rectifier bridge heat sink body, right arm top is respectively equipped with the level connection joint section and bolt press-in hole that outwards stretch, described level connection joint section is provided with rivet and presses hole, on a left side for rectifier bridge heat sink body, right arm upper, lower surface position and rectifier bridge heat sink body 1 two bottom sides between adjacent two diode press-in hole are respectively equipped with radiating fin I.Because rectifier bridge heat sink body is V-arrangement, by drawing and forming, production efficiency is high, and stretch without the need to special mfg. moulding die, processing cost is low, saves material and processes conveniently; Structure is simple, and draught area is large, and thermal diffusivity is good.
Description
Technical field
The utility model relates to a kind of alternator rectifying bridge for vehicle fin.
Background technology
Alternator rectifying bridge for vehicle mainly contains following parts and forms: positive and negative electrode fin, positive and negative electrode diode, circuit board and bolt; Wherein positive and negative electrode diode is pressed in both positive and negative polarity fin respectively, and together with installing to circuit board group, bolt is tightened through after both positive and negative polarity fin.Fin is produced by die casting, and its shape is semicircle, as shown in Figure 1.Problems existing is: 1, fin is produced by die casting, and production efficiency is low; 2, the manufacturing cost of die casting itself is high; 3, after die casting completes, the exterior mold that rushes of being correlated with also is needed to process, waste material; 4, the semicircle fin in a plane need ensure that draughty simultaneously also need of fin reasonably arranges diode location, but for six diode product, because number of diodes is many, is difficult to rational deployment, cannot meet the requirement of product.
Utility model content
The purpose of this utility model to solve the problems referred to above that prior art exists, provide that a kind of production efficiency is high, material-saving, can the alternator rectifying bridge for vehicle fin of reasonable Arrangement six diodes.
The utility model is achieved in that alternator rectifying bridge for vehicle fin, comprise rectifier bridge heat sink body 1, its special character is: described rectifier bridge heat sink body 1 is left for V-arrangement, right symmetry, left arm and the right arm of rectifier bridge heat sink body 1 are respectively equipped with a left side along its length, three diode press-in hole 2 of right symmetry, at the left arm of rectifier bridge heat sink body 1, right arm top is respectively equipped with the level connection joint section 3 outwards stretched, on a described left side, the top of right arm is provided with bolt press-in hole 4, described level connection joint section 3 is provided with rivet and presses hole 5, on a left side for rectifier bridge heat sink body 1, right arm upper, lower surface position and rectifier bridge heat sink body 1 two bottom sides between adjacent two diode press-in hole 2 are respectively equipped with radiating fin I 6.
On the left and right arm of described rectifier bridge heat sink body 1, the corresponding diode press-in hole outer fix being positioned at left and right arm top is provided with radiating fin II 8 respectively.
The beneficial effects of the utility model are: 1, because rectifier bridge heat sink body is V-arrangement, by drawing and forming, production efficiency is high; 2, stretching mode is realized by special stretcher, and do not need special mfg. moulding die, processing cost is low; 3, after having stretched, without the need to other technology modes except simple deflashing process, therefore save material and process conveniently; 4, structure is simple, and respectively can reasonable Arrangement 1-3 diode on the left and right arm of fin, because the upper and lower surface of left and right arm is respectively equipped with radiating fin bottom position and rectifier bridge heat sink body between adjacent two diodes, draught area is large, and thermal diffusivity is good.
