Description
Technical field
The utility model relates to the power rectifier assembly, is specifically related to a kind of electric welding machine rectifier stack.
Background technology
At present, electric welding machine generally adopts AC power.Need in the electric welding machine course of work AC power to be carried out rectification by the power rectifier assembly, existing electric welding machine rectifier stack, all adopt the heat radiation of single piece aluminum fin: crimping band tooth copper sheet on aluminium radiator fin, soldering connects a utmost point of diode on copper sheet, another utmost point soldering connects thin copper wire, means of spot welds copper sheet or iron plate on the copper wire extraction pole.Its shortcoming has: 1) rectifier diode is the heat radiation of monolithic aluminium flake, and heat-sinking capability is poor, allows power output little.2) during crimping band tooth copper sheet, often occur the slit between copper sheet and the aluminium flake, soldering connects, the rosin joint phenomenon appears in means of spot welds often, causes the rectifier stack contact resistance big, and power consumption is big, and product quality and reliability are difficult to guarantee.3) use of thin copper wire electrode, ferrous material and complex manufacturing increase whole assembly production cost, appearance poor, and useful life is short.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing electric welding machine rectifier stack, provide a kind of heat-sinking capability strong, allow that power output is big, the electric welding machine rectifier stack of dependable performance, long service life, economize on electricity.
The purpose of this utility model is achieved through the following technical solutions.
A kind of electric welding machine rectifier stack, it comprises plastic packaging rectifier diode group, diode anode, diode cathode, aluminium radiator fin group etc., diode anode, diode cathode soldering are connected on the silver-plated stack of rivets of copper, run through the aluminium radiator fin group and diode anode, diode cathode and the stack of rivets that connect the diode group and are riveted together; Insulating ceramics ring, fastening screw and screw rod insulating sleeve, nut, pad and aluminium radiator fin group are fastenedly connected assembling.Design is useful on the hole that reduces rectifier diode stress on the aluminium radiator fin group.
It is strong that electric welding machine rectifier stack of the present utility model has heat-sinking capability, allows power output big, dependable performance, long service life and economize on electricity, advantage such as production cost is low, and is simple for assembly process, aesthetic in appearance.
Description of drawings
Fig. 1 is a plan structure schematic diagram of the present utility model;
Fig. 2 is a main TV structure schematic diagram of the present utility model.
Among the figure: 1, diode group, 2, stack of rivets, 3, the aluminium radiator fin group, 4, the insulating ceramics ring, 5, the hole, 6, fastening screw, 7, nut, 8, pad, 9, diode anode, 10, diode cathode.
Embodiment
Referring to Fig. 1, Fig. 2, the electric welding machine rectifier stack, by plastic packaging rectifier diode group 1, with the anode of plastic packaging rectifier diode group, the silver-plated stack of rivets 2 of copper that the negative electrode soldering is connected together, and the formations such as aluminium radiator fin group 3 that are riveted together with diode anode, negative electrode stack of rivets, design has a hole 5 that reduces rectifier diode stress on the aluminium radiator fin group, with aluminium radiator fin group 3 tightens together insulating ceramics ring 4, fastening screw 6 and screw rod insulating sleeve, nut 7 and pad 8 is arranged.
Therefore anode, the negative electrode of described plastic packaging rectifier diode group is that soldering is connected on the silver-plated rivet, because of the rivet area is bigger than thin copper wire cross-sectional area, increased the bonding area of rectifier diode anode, negative electrode.Because rivet is silver-plated, in the soldering termination process, avoided the rosin joint phenomenon again.Above-mentioned measure has guaranteed the welding quality of rectifier diode group and stack of rivets, has reached the purpose that reduces contact resistance and product power consumption, has improved product quality, has prolonged the useful life of product.
The described aluminium radiator fin group 3 that is riveted together with rectifier diode anode, negative electrode stack of rivets, because of rivet and fin are riveted together, under the effect of rivet force, rivet and aluminium radiator fin form and combine closely, and have avoided the between cog slit of band tooth copper sheet and aluminium radiator fin.Reached the purpose that reduces contact resistance and product power consumption equally, made product quality and reliability obtain further raising.
The anode surface of rectifier diode group, cathode plane are riveted together by stack of rivets and groups of fins, formed the two-sided heat radiation of rectifier diode, its area of dissipation is doubled, heat-sinking capability strengthens, the permission power output increases, under equal conditions the rectifier diode junction temperature reduces, the reliability and the useful life of further having improved rectifier stack.Simultaneously, because of having removed materials such as thin copper wire electrode, iron plate, make rectifier stack technology obtain simplifying, production cost reduces, and is aesthetic in appearance.
The design of aluminium radiator fin group has the hole 5 that reduces rectifier diode stress, by the design in this hole, makes rectifier stack drop to minimum to the fastening stress that rectifier diode forms in fastening process, has effectively guaranteed the useful life and the product quality of rectifier stack.
The insulating ceramics ring 4, screw rod 6, nut 7, pad 8 and the screw rod insulating sleeve that tighten together with the aluminium radiator fin group, play between aluminium radiator fin and the aluminium radiator fin, insulation between aluminium radiator fin and the fastening screw and fastening effect, thereby guaranteed between rectifier diode group negative electrode, anode and the insulation property between aluminium radiator fin and fastening screw, the fail safe that has improved electric welding machine.
More than basic principle of the present utility model, principal character and advantage have been described in explanation.Utility model is not subjected to the limitation of above-mentioned execution mode, and various changes and modifications can also be arranged, and these changes and improvements all fall into protection range of the present utility model.
