Description
Technical field
It the utility model is related to the attachment structure for the fin being connected with wiring board.
Background technology
Due to there is some PCBA (Printed Circuit Board Assembly's writes a Chinese character in simplified form, and printed circuit integrates) plates to exist
Substantial amounts of heat can be produced during work, it is therefore desirable to some fin are connected in the circuit board to be radiated, to extend
The service life of PCBA board.Fin is provided with the screw being correspondingly arranged with wiring board in the prior art, passes through spiral shell between the two
Line is connected, and due to gap between wiring board and fin be present, in order to be completely embedded, passes through between fin and wiring board
It is screwed again after hollow plastic column docking.Such connected mode, needed when installing fin manually by wiring board
On screw, the screw on stud and fin align two-by-two, positioning is cumbersome.
Utility model content
In order to solve the above problems, the purpose of this utility model is to provide a kind of positioning simply, and attachment structure is reliable, dissipates
The attachment structure of the fin of good in thermal property.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
A kind of attachment structure of fin, including fin and wiring board, fin include integrally formed heat-dissipating fin
And connection sheet, connection sheet are provided with some self-clinching standoffs, wiring board is provided with screw corresponding with the self-clinching standoff, and press spiral shell
Post uses screw connection again after being aligned with screw；Screw positioning hole is reserved on fin, connects and completes between fin and wiring board
Afterwards, set metal bead that the high component of wiring board caloric value is pressed into upper fin.
Preferably, on fin on corresponding line plate the intensive position of electrical equipment link position, radiating
Self-clinching standoff on piece replaces with plastics stud, and the plastic spiral column bottom sets inserting column, and fin is provided with jack, plastics
Stud coordinates with fin grafting
Preferably, PUR is covered at the nut or nut of threaded connection place in the circuit board.
Preferably, being arranged with some short slots on conplane two short side on a heat sink, the short slot can be set
Put in heat-dissipating fin or connection sheet.
Preferably, the fin is single aluminium flake form.
The attachment structure of above-mentioned fin, self-clinching standoff is set to substitute plastic hollow pipe independent in the prior art, positioning
It is convenient, and after the completion of fin is connected with wiring board, by metal bead by the big component pressure of caloric value on wiring board
Fin, to strengthen radiating effect.
Brief description of the drawings
Fig. 1 is the top view of fin in the utility model.
Fig. 2 is the front view of fin in the utility model.
Fig. 3 is the side view of fin in the utility model.
Wherein：1st, connection sheet, 11, self-clinching standoff, 12, connect the screw of hollow plastic pipe, 2, heat-dissipating fin, 21, screw
Positioning hole, 3, short slot.
Embodiment
The preferred embodiment of this patent is described in further detail below in conjunction with the accompanying drawings.
A kind of attachment structure of fin, including wiring board and fin, the wherein structure of fin as shown in Figures 1 to 3,
Including integrally formed heat-dissipating fin 2 and connection sheet 1, it is mutually perpendicular between the heat-dissipating fin 2 and connection sheet 1.In connection sheet 1
Provided with some self-clinching standoffs 11, wiring board is provided with screw corresponding with the self-clinching standoff, and self-clinching standoff 11 is aligned with screw
Use screw connection again afterwards, after screw installation, PUR is filled out on the nut of connection line plate and the screw of fin, set
PUR one side energy fixed screw, prevent from causing loosened screw during carrying in the later stage, while extraneous air can be completely cut off,
Avoid oxidation and cause the thread damage of screw so as to situation about can not be dismantled when resulting in the need for and repairing.
Preferably, on fin on corresponding line plate the intensive position of electrical equipment link position, radiating
Self-clinching standoff on piece replaces with plastics stud, and the plastic spiral column bottom sets inserting column, and fin is provided with jack, plastics
Stud coordinates with fin grafting.The self-clinching standoff of the position is replaced with into plastics stud, due to the peace of component in PCBA board
Full distance is too small, prevents that the pressing-riveting bolt due to metal from causing short circuit.
Screw positioning hole 21 is reserved on fin, after the completion of being connected between fin and wiring board, sets metal bead will
Metal-oxide-semiconductor on wiring board, rectifier bridge and diode constant power is big, caloric value is high component press to fin, and metal bead passes through
It is bolted to fin.Contact area between component and fin is increased by metal bead, preferably dissipated with reaching
Thermal effect.Preferably, the component of fin is pressed to by metal bead, between these components and the contact surface of fin
Provided with heat-conducting glue, further to strengthen radiating effect.
Preferably, the fin in the present embodiment, using single aluminium flake form simple in construction, has simple in construction, weight
Amount is light, the advantages of perfect heat-dissipating.
When connecting fin with wiring board, the position of fin is fixed by machine first, prevents it in the turn of the screw
During rotate, the long side of the long side of heat-dissipating fin and connection sheet connects, in order to facilitate fixing cooling fins, in fin
Some short slots 3 are arranged with upper conplane two short side, the short slot 3 can be set in heat-dissipating fin 2 or connection sheet 1.
The short slot coordinates with the positioner in stationary machines, is positioned by short slot, is adapted to different machines screw positioning spacing
Difference, reduce fin cross multiple types, with facilitate management, installation.
