Description
The utility model relates to the manufacturing frock of the Secondary Power Module in the electric equipment products, is specifically related in a kind of manufacturing frock of big or middle power model power supply, is used for fixing the heat-radiating aluminum plate in the power supply so that carry out the anchor clamps of subsequent production operation.
Secondary Power Module is as a branch of Switching Power Supply, all obtained application more and more widely in a lot of fields at present, and wherein, the high power density modular power source is one of at present main development trend, but its volume and heat radiation are the problems that must consider.
Greatly, middle power model power supply and some adopt in the electrical equipment of power components, as Switching Power Supply, the power amplification output block, row in television set and the computer, field-scanning circuit generally all is operated in high voltage, current state, can produce a large amount of heats when therefore working, as not taking measures, will influence the useful life of these parts, for solving the heat dissipation problem of above-mentioned parts, usually adopt the aluminium base process program to improve radiating effect, this scheme generally adopts double-layer structure, the upper strata is a control board, lower floor is an aluminium base, components and parts on control board are less demanding to dispelling the heat, what install on lower floor's aluminium base then is the power tube and the magnetic elements of heating, realize electrical equipment and physical connection by contact pin between two-layer, so just, the good performance of heat dissipation that can utilize aluminium base distributes the heat that power tube and magnetic element produce, and reduces the temperature of power tube and magnetic elements.Though adopt this process program of aluminium base to solve heat dissipation problem, also have some problems in the paster production process of aluminium base.For example, in the manufacture process of electronic circuit board, adopt the mode of production of wave-soldering or paster, then to the production of common PCB (printed circuit board (PCB)) plate, the transmission limit that needs to reserve two 〉=3.5mm width on the dual-side of pcb board was used for wave-soldering or paster production.Usually the limit is transmitted as it in two long limits of the layout after PCB or the layout in the production, so that on streamline, transmit.As transmitting the limit, its positive and negative can not have any components and parts or pin in the scope of limit 3.5mm (138mil).When the wiring of pcb board can't reach requirement, can reach requirement by the mode of jigsaw, the connected mode of common jigsaw mainly contain two-sided to carve " V " shape groove, long slot bore adds circular hole and three kinds of modes of long slot bore.
In the paster production process of heat-radiating aluminum plate (as, cross wave-soldering), when the above-mentioned transmission limit that can not satisfy wave-soldering requires, also can adopt the jigsaw mode to solve, the jigsaw mode of the pcb board of the jigsaw mode of the aluminium base that is now adopted and employing common material identical (mode of " V " shape groove and long slot bore combination or whole " V " type groove mode that adopts), there is following shortcoming at present in this mode:
The pcb board of common material can adopt board separator to carry out the branch plate, but board separator can't divide aluminum alloy materials when minute plate, so aluminium base makes the device at edge be subjected to the damage that may can't find easily when production test, reduces device useful life; The 2nd, can leave the vestige (burr) of branch plate at the periphery of aluminium base, influence attractive in appearance; The 3rd, plate mode efficient was low in this minute.Transmit the limit requirement even can satisfy behind the branch plate, the production of aluminium base still adopts the mode of monolithic to carry out, and production efficiency is very low.
The purpose of this utility model is, the anchor clamps that provide a kind of heat-radiating aluminum plate to use, can overcome above-mentioned shortcoming of the prior art, using this anchor clamps can make aluminium base need not carry out the branch plate in process of production handles, can realize the production of aluminium base, can realize that also the polylith aluminium base produces the production efficiency height simultaneously, and clamp structure is simple, is easy to realize.
The purpose of this utility model is to realize like this, construct the anchor clamps that a kind of heat-radiating aluminum plate is used, comprise substrate, be provided with at least one groove that is used to place aluminium base in the described substrate, the width of described groove is slightly larger than the width of aluminium base, the bottom of described groove is provided with at least one and is convenient to the flat crosswise through hole that the monolithic aluminium base is laid, and is provided with the alignment pin that at least one is used for monolithic aluminium base location at bottom land near the edge of described through hole.
Above-mentioned according to anchor clamps provided by the utility model in, the edge of described groove also is provided with the lock-screw that is used to lock the monolithic aluminium base.
Above-mentioned according to anchor clamps provided by the utility model in, be provided with two or more flat crosswise through holes of being convenient to lay two or polylith aluminium base in the described groove, the edge of described groove is provided with a plurality of lock-screws corresponding to every aluminium base.
Above-mentioned according to anchor clamps provided by the utility model in, be provided with the alignment pin that the diagonal angle distributes that is in the edge of described through hole corresponding to the monolithic aluminium base.
Above-mentioned according to anchor clamps provided by the utility model in, the top ovalize structure of described lock-screw.
The anchor clamps that the heat-radiating aluminum plate that implementing the utility model provides is used, by in a substrate, being provided for laying groove, aluminium base alignment pin and the lock screw of aluminium base, can make the aluminium base that does not possess wave-soldering transmission requirement need not divide plate in process of production, can satisfy the transmission limit requirement of wave-soldering, realize the production of aluminium base, the utility model both can be used for the production that the monolithic aluminium base also can be used for the polylith aluminium base, can not damage components and parts, simple and practical, the production efficiency height has overcome the defective in the primary aluminum substrate production process.
Below in conjunction with accompanying drawing, further specify the utility model with preferred embodiment, in the accompanying drawing:
The structural representation of the embodiment of anchor clamps that Fig. 1 uses for the heat-radiating aluminum plate that provides according to the utility model;
