Abstract
The utility model relates to an aluminum-based board, concretely a diode aluminum-based board, comprising the board body of the aluminum-based board contacting with the diode directly. The surface of the board body of the aluminum-based board contacting with the diode is covered by a PCB board, and the surface of the board body of the aluminum-based board backward to the diode is the concave convex face favorable for dissipating heat. The PCB board is provided with a round hole for the diode crossing. The bottom of the diode clings to the surface of the board body of the aluminum-based board through the round hole, fixed via a detachable card fixing assembly. Compared with the prior technology, the utility model is simple in structure, safe and not polluted, overcoming the welding form defect of the prior form, and making the board body of the aluminum-based board design as a heterotype with an irregular heat-delivery surface. The production and assemblage are quicker, and the dissipating heat effect is more ideal.
Description
Technical field
The utility model relates to a kind of aluminium base, and specifically a kind of diode that is beneficial to carries out the heat-radiating aluminum plate.
Background technology
Existing diode aluminium base, being metal solder between diode and the aluminium base fixes, because the difference of material, be subjected to very big influence in the welding position pyroconductivity, heat is slow to aluminium base speed from diodes conduct, and the heat that diode produces can not scatter and disappear rapidly, and radiating effect is undesirable, cause diode to quicken owing to overheated that it is aging easily, shorten diode useful life.Simultaneously, owing to contain poisonous metal in the scolding tin,, do not meet the requirement of green product so the fixed form of this metal solder is bigger to environment and operating worker negative effect when producing.
The utility model content
The technical problems to be solved in the utility model provides the diode aluminium base that can dismantle flexibly between a kind of good heat dissipation effect, diode and the aluminium base plate body.
According to above-mentioned specification requirement, the utility model is realized by the following technical solutions:
A kind of diode aluminium base, comprise the aluminium base plate body that directly contacts with diode, the surface that the aluminium base plate body contacts with diode is glued with pcb board, and the aluminium base plate body is the male and fomale(M﹠F) that for the benefit of dispels the heat of diode face dorsad, has to be used for the circular hole that diode passes through on pcb board.
Above-mentioned diode bottom is passed circular hole and is close to aluminium base plate body surface, and fixes by a dismountable fixing assembly.
Above-mentioned fixing assembly comprises a spring leaf and the carbine that is installed on the spring leaf two ends, and spring leaf is across on the aluminium base plate body, and the carbine other end is fixed on the aluminium base plate body.
Above-mentioned carbine and spring leaf link have a plurality of square holes arranged side by side, and an end of spring leaf interts in square hole, and the other end of carbine bends to barb, and barb is fastened on the aluminium base plate body.The spring leaf two ends are upturned, and the end has bayonet socket, and bayonet socket directly is fastened in the square hole, also have the circular hole of hoop cover diode at the spring leaf middle part.Fix after assembly installs fully, the elastic force by spring leaf is hooked on the aluminium base plate body carbine all the time, when bayonet socket is fastened in the different square holes, can reach the purpose of regulating spring sheet elastic force.
In order to increase the area of dissipation of aluminium base plate body, the aluminium base plate body dorsad the diode face be male and fomale(M﹠F), be formed with the fixedly recess of barb in side near carbine.
Compared with prior art, the utility model is simple in structure, it is faster to produce assembling, and overcome the defective of Type of Welding in the existing mode, safety non-pollution, the aluminium base plate body is designed to the rough shaped body of radiating surface, and radiating effect is better, is more suitable in heavy-duty diode heat radiation occasion.
