Abstract
The utility model discloses an integrated circuit lead frame fin, including the fin main part, four angles in the front of fin main part all are equipped with supporting seat, every all be equipped with the projection on the supporting seat, the fin main part with the supporting seat the supporting seat with the projection is integrated into one piece structure, every the other platform that still is equipped with of supporting seat, four angles of reverse side of fin main part still are equipped with the recess, the position of recess with the position of projection is corresponding, the utility model discloses a setting up the mode of platform at four angles in the front of fin main part, making and form certain gap between the fin each other, projection on previous fin is behind the reinsertion among fin recess, has avoided the lock phenomenon of fin from the face, and the barrel -plating of being convenient for makes the product in the back of moulding plastics simultaneously, between fin and the plastic envelope material combination inseparabler, readily releasable not.
Description
Technical field
The utility model belongs to the technical field of fin, particularly relates to a kind of circuit lead frame fin.
Background technology
The surface treatment mode of current circuit lead frame fin is plated by volume before and is being transitioned into barrel plating processing, but due to the projection on existing circuit lead frame fin and groove structure, easily cause product can mutually snap together in barrel plating process, cause poor plating; On the other hand because fin front is more flat, easily cause fin front also more weak with the adhesion between plastic packaging material.
In view of this, the present inventor studies and devises a kind of circuit lead frame fin, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of circuit lead frame fin,
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of circuit lead frame fin, comprise heat sink body, the angle, four, front of described heat sink body is equipped with supporting seat, each described supporting seat is equipped with projection, described heat sink body and described supporting seat, described supporting seat and described projection are integrated formed structure, each described supporting seat is other is also provided with a platform, and reverse side four angles of described heat sink body are also provided with groove, and the position of described groove is corresponding with the position of described projection.
As the optimal way of embodiment, described platform is back taper structure.
As the optimal way of embodiment, described groove size just can place described projection.
Because a kind of circuit lead frame of the utility model fin takes above-mentioned technical scheme, namely heat sink body is comprised, the angle, four, front of described heat sink body is equipped with supporting seat, each described supporting seat is equipped with projection, described heat sink body and described supporting seat, described supporting seat and described projection are integrated formed structure, each described supporting seat is other is also provided with a platform, reverse side four angles of described heat sink body are also provided with groove, and the position of described groove is corresponding with the position of described projection; Projection between the utility model is no longer inserted among groove, avoids the fastening phenomenon between fin from face, be convenient to barrel plating, make product simultaneously after injection moulding, combine more tight, not easily separated between fin and plastic packaging material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model side schematic view.
Embodiment
As depicted in figs. 1 and 2, the utility model discloses a kind of circuit lead frame fin, comprise heat sink body 1, the angle, four, front of described heat sink body is equipped with supporting seat 2, each described supporting seat 2 is equipped with projection 3, described heat sink body 1 and described supporting seat 2, described supporting seat 2 are integrated formed structure with described projection 3, each described supporting seat 2 is other is also provided with a platform 4, reverse side four angles of described heat sink body 1 are also provided with groove 5, and the position of described groove 5 is corresponding with the position of described projection 3.
As the optimal way of embodiment, described platform 4 is back taper structure.
As the optimal way of embodiment, described groove 5 size just can place described projection 3.
The utility model is in barrel plating process, by arranging the mode of platform at angle, four, the front of heat sink body, make mutually to form certain gap between fin, projection on previous fin no longer inserts among a rear fin groove, avoid the fastening phenomenon of fin from face, be convenient to barrel plating; In addition in injection moulding process, platform is set at angle, four, the front of heat sink body and can makes to combine between fin and plastic packaging material more tight, not easily separated.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
Claims (3)
1. a circuit lead frame fin, it is characterized in that: comprise heat sink body, the angle, four, front of described heat sink body is equipped with supporting seat, each described supporting seat is equipped with projection, described heat sink body and described supporting seat, described supporting seat and described projection are integrated formed structure, each described supporting seat is other is also provided with a platform, and reverse side four angles of described heat sink body are also provided with groove, and the position of described groove is corresponding with the position of described projection.
2. a kind of circuit lead frame fin as claimed in claim 1, is characterized in that: described platform is back taper structure.
3. a kind of circuit lead frame fin as claimed in claim 1, is characterized in that: described groove size just can place described projection.
