Description
The utility model relates to a kind of supply unit that has power component and radiator, particularly relates to the installation annexation between each element in this device.
In the modular power source product, components and parts all are connected in the printed board by soldering, the electric connection between the realization components and parts and fixing.But when high-power, owing to the relative printed board with the transformer equal-volume of power device weighs greatly, printed board can't be born its weight and be produced deformation, and the time has been grown problems such as can causing the Copper Foil wire fracture, causes product failure.Simultaneously, in the large power supply, bigger thermal losses need add the radiator of respective volume to reduce the product temperature rise.
Current is head it off, and often in the following ways: one, do a cuboid can, an opening is put into box body with the printed board that welds element, all with colloid they is fixed as one then.The shortcoming of this mode is a maintenance difficult, almost can not keep in repair; The efficiently radiates heat area only is the area of box body, and is big inadequately.Two, adopt aluminium base technology, printed board thickness is accomplished below the 0.3mm, paste on the aluminium sheet, make aluminium base; All components and parts all are welded on the aluminium base, finish being electrically connected and mechanical fixation.Its shortcoming is that cost is higher, and process equipment and technology difficulty are bigger, and domestic now can't the realization produced in enormous quantities.Three, aluminium base and printed board hybrid technique.High-power, big current element device is welded on the aluminium base, realizes being electrically connected and fixing; Small components, control assembly are welded in the printed board, with contact pin two plates are electrically connected again and are fixed together.But this scheme technology is still immature, is in the stage of fumbling.
The purpose of this utility model is exactly to provide a kind of modular power source device design in order to overcome the above problems, to realize simple, easy to use, with low cost and its purpose that thermal effect is good, moulding is also more attractive in appearance of technology.
The utility model realizes that the scheme of above-mentioned purpose is: a kind of circuit arrangement, and comprise PCB circuit board 1, be installed on power component 2, radiator 3 and shell 7 etc. on the pcb board 1, it is characterized in that: described shell 7 and radiator 3 are in the both sides of pcb board 1 respectively; On radiator 3, be provided with shoulder 4, on the described shoulder 4 screw 5 arranged corresponding to power component 2 places; There is through hole 6 in place at pcb board 1 corresponding screw 5, and there is through hole 6 ' in the place of corresponding screw 5 on the shell 7, and the through hole 6 on the pcb board 1 is located at place, power component 2 places; Between the fin of radiator 3 and power component 2, also be lined with a dielectric film 8, through hole 6 is arranged on the dielectric film 8 "; screw 9 is by the through hole 6 ' on the through hole on the pcb board 6, the shell, through hole 6 on the dielectric film " back matches with screw 5, and whole device is fastening.
Owing to adopted above scheme, by shell 7 and radiator 3 with pcb board 1 and on all elements be enclosed in inside, make it handsome in appearance and compact conformation is solid; Power component 2 corresponding positions have screw 9 fastening, have both strengthened radiating effect, make fixed effect good again; Owing to be removable structure, whole device for ease of maintenaince, and is easy to use, and technology is simple, is easy to produce in batches.
Fig. 1 is the whole assembling of a utility model embodiment view.
Fig. 2 a, 2b, 2c are respectively the analysing and observe of shell among the utility model embodiment, medial surface, lateral surface schematic diagram.
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
See Fig. 1, be depicted as a kind of circuit arrangement, comprise PCB circuit board 1, be installed on power component 2 on the pcb board 1, radiator 3, shell 7 etc., described shell 7 and radiator 3 are in the both sides of pcb board 1 respectively; On radiator 3, be provided with shoulder 4, on the described shoulder 4 screw 5 arranged corresponding to power component 2 places; There is through hole 6 in place at pcb board 1 corresponding screw 5, and there is through hole 6 ' in the place of corresponding screw 5 on the shell 7, and the through hole 6 on the pcb board 1 is located at place, power component 2 places; Between the fin of power component 2 and radiator 3, also be lined with a dielectric film 8, through hole 6 is arranged on the dielectric film 8 "; screw 9 is by the through hole 6 ' on the through hole on the pcb board 6, the shell, through hole 6 on the dielectric film " back matches with screw 5, and whole device is fastening.
The shape of each through hole and the size as described below: the through hole 6 on the dielectric film " match with shoulder 4, so its size greater than the size of shoulder 4, its shape is then similar to the shape of shoulder 4; Through hole 6 and the through hole 6 ' on the shell on the pcb board match with screw 9, its internal diameter is a bit larger tham the footpath of locating of screw 9, its shape can be done circular, wherein the through hole on the pcb board 6 is suitably big, it is described to see below, so that the raised brim 12 that is presented a theatrical performance as the last item on a programme on 10 in the inboard of plastic casing 7 can be inserted in wherein.
Described shell 7 is a plastic material, also can adopt other insulating material, presents a theatrical performance as the last item on a programme 10 what the interior side through hole 6 ' of shell 7 had a projection all around, so that can be pressed in place, power component 2 places on the pcb board 1 after installing.
Described shoulder 4 is a square column type, or the projection of other shapes, and it mainly acts on is that its center is provided with screw 5, is used for cooperating with screw 9, fixing whole device.Directly do not beat screw if do not adopt this shoulder 4 on radiator, then screw 9 passes the base plate of radiator 3, influences product shape; At product height one regularly, if increase the thickness of radiator 3, then area of dissipation obviously reduces.
See Fig. 2, describedly present a theatrical performance as the last item on a programme 10 for having the garden annular of two wings 11.10 the employing of presenting a theatrical performance as the last item on a programme is for fastening force is concentrated on the power device 2; The employing of two wings 11 then is in order to enlarge contact-making surface, to reduce pressure.In fact the more wing can be set on 10 presenting a theatrical performance as the last item on a programme, with further dispersive pressure, this only is subject to the arrangements of elements of pcb board 1, only otherwise be pressed onto element, can enlarge arbitrarily in principle and present a theatrical performance as the last item on a programme and the contact-making surface of pcb board (will consider simultaneously corresponding, so also be not to be the bigger the better) with the position at power component 2 places.In addition, presenting a theatrical performance as the last item on a programme has the edge 12 of projection on 10 all around around through hole 6 ', and this edge 12 can be inserted in the through hole 6 on the pcb board, plays the role of positioning.
In a word, the utility model is a kind of shell-type structure that has, by on the shell present a theatrical performance as the last item on a programme and radiator on realization such as shoulder compressing and fixing to radiator, power component etc.This structure is easy to install, dismantles, keeps in repair, and attractive in appearance, practical, radiating effect and fastening effective all fine.
Supply unit disclosed in the utility model removes and can be widely used in the modular power source China and foreign countries, also can be used for other supply units and even all comprise in the circuit of power component and radiator.Have great practical value.
