Description

A kind of improved composite bus bar

Technical field

The utility model relates to a kind of improved composite bus bar.

Background technology

At present general composite bus bar all adopts rigidity or semi-rigid insulation board and conductor plate composite construction, and splicing ear generally adopts riveted joint or soldering copper post on conductor plate; Then adopt a plurality of composite bus bars to adopt splicing ear to connect for the polymorphic structure product, or adopt complicated moulding particular manufacturing craft that semi-rigid insulating material and preforming conductor plate compound die are pressed into a rigid structure body, the insulation chock is preset in the port insulation employing of compound back structure or the opening sealing adhesive process is done the insulation sealing, and, environment for use cleaner situation tight for dimensional requirement also can adopt reservation insulation distance mode to guarantee electric insulation.Heavier, the required moulding mould special expense of this infrastructure product weight height, structure is not compact during three-dimensional the connection, electric property does not reach optimum efficiency, and adopts the particular manufacturing craft mould pressing process and adopt the production efficiency of insulating cement sealing adhesive process processing composite bus bar low.

The utility model content

The purpose of this utility model is to provide that a kind of manufacture craft is simple, production efficiency is high, the improved composite bus bar of good insulation preformance.

The purpose of this utility model is achieved through the following technical solutions:

Improved composite bus bar comprises the conductor plate that is fixed with the copper post, by the connection boss of conductor plate bulk material machine-shaping and stick on the insulating barrier on conductor plate surface, described insulating barrier is the gluing dielectric film, the insulation edge sealing that middle opening on conductor plate and position, edge have the gluing dielectric film body on conductor plate surface to form.

Improved composite bus bar can be made by the following method:

1) processing conductor plate connects boss and adopts the bulk material punch forming on the conductor plate, the welding conductors post is also electroplated required coating as required on conductor plate;

2) according to the flexible gluing dielectric film of the shape cutting of the conductor plate of step 1), on the dielectric film with conductor plate on the corresponding position of middle opening and edge reserve 3～15mm insulation edge sealing;

3) with step 2) dielectric film stick on the top and bottom of conductor plate by the shape correspondence of conductor plate;

4) conductor plate (individual layer or two-layer) of step 3) is placed the interior pressurized, heated of flat type cavity mould (according to the different different parameters of selecting for use of the thickness of selecting coating glue film material and composite bus bar for use, 100～200 ℃ of general pressure 15～30Kg/cm2, temperature) carry out hot pressing, dielectric film and conductor plate are become one, make the dielectric film that middle opening and position, edge are reserved on the conductor plate be pressed into one up and down simultaneously, make composite bus bar;

5) cooling mould unloading;

6) composite bus bar with step 5) is bent into required form with instrument or Mould Machining.

Adopt the composite bus bar of this insulation system to have the following advantages: the one, institute's materials used is an insulation film, very thin thickness, the compound back of multilayer pole plate layer insulation dielectric thickness is little, and is very little as the self-induction of the row of being electrically connected, good electric property; The 2nd and since the cost class of the insulation film that uses and composite article thereof all have from low to high, can carry out categorizing selection according to the product application need, the compound material cost is relatively low, and do not need additionally to adopt other material to carry out edge opening secondary seal, the clipped operation reduces product cost; The 3rd, before the final bending and molding of product, product is processed in dull and stereotyped mode basically, is bent into special shape after dull and stereotyped pressing again, can realize the multilayer pressing that superposes simultaneously, and the production efficiency height is fit to produce in enormous quantities; The 4th, required pressing mold thinner thickness, difficulty of processing reduces, and the Mould Machining time is shorter relatively; The 5th, the product final molding does not need special-purpose bending and molding mould, and the mould overhead cost is relatively low; The 6th, product is plane multilayer pressing in the pressing process, and All Ranges is evenly stressed, and the properties of product consistent performance is good, the reliability height; The 7th, insulation film weight proportion in the composite bus bar product structure is little, and entire product weight other infrastructure product that compares is light; The 8th, more multi-layered integrated comparatively easy when being assembled into the labyrinth busbar.

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment

Improved composite bus bar has the individual layer conductor structure, sees Fig. 1, Fig. 2, and it is the surperficial sticking flexible gluing dielectric film at one deck conductor plate; The double-layer conductor structure is also arranged, see Fig. 3 to Figure 10, it is pasted superimposed composition of two-layer conductor plate of flexible gluing dielectric film by the surface.Composite bus bar comprises conductor plate (copper coin and aluminium sheet etc.) 4, be welded with the copper post 1 of charged coating on the conductor plate 4, there is conductor plate to connect whole boss 5 on the composite bus bar, be pasted with gluing dielectric film 3 with good bending property on conductor plate 4 surfaces, gluing dielectric film 3 can adopt PET (gluing polyester film), PI (polyester-imide film), PEN, TEDLAR etc., the insulation edge sealing 2 that middle opening on the conductor plate and position, edge have the gluing dielectric film body on conductor plate surface to form.

The 3 general employings of gluing insulation film scribble the single spreading dielectric film (as Figure 11) and the double spread dielectric film (as Figure 12) of flexible viscose glue in advance.Pre-gluing 32 promptly is coated on glue on the dielectric film matrix 31 in advance, and coated face has single or double, and treated one-tenth semi-cured state does not have adhesive power when operating under the normality, has adhesive property when pressurized, heated.The kind of insulation film is selected according to thermal endurance class that product requires and requirement of withstand voltage, and thickness generally uses at 0.05mm～0.5mm or multiple layer combination; The thickness of conductor plate requires to select according to size of current.Because film and conductor plate all have good bending property, product can continue to be bent into needed shape at bending part a as required after the pressing.

Composite bus bar is seen Figure 13 with flat type cavity mould hot pressing situation, and the centre is the dull and stereotyped composite bus bar of the not bending and molding after the pressing, and upper and lower is flat type cavity mould.
